==Explanation==
The "comic" is actually a {{w|browser game}} made to celebrate the release of [[Randall|Randall's]] new book, ''[[Thing Explainer]]'', which was released on the same day as this comic: ''Tuesday'' November 24, 2015. The comic thus appeared on a Tuesday, replacing that week's normal Wednesday release to coincide with the release day.

The title refers to a {{w|hoverboard}} (which resembles a hovering skateboard without wheels) which has been most [https://www.youtube.com/watch?v=z1ZdMOMUgXE prominently featured] in the movie {{w|Back to the Future Part II}}, which took place in the future, until a little more than a month before this comic was released. {{w|Marty McFly}} traveled to the future in this second installment, more precisely to [https://www.facebook.com/October212015BTTF 2015-10-21], and this comic were released just over one month later 2015-11-24. Hoverboards are just one of many things predicted in Back to the Future Part II, that [http://www.bbc.com/news/technology-33785285 h][https://www.youtube.com/watch?v=4HI137m7XA4 a][https://www.youtube.com/watch?v=SLwNGBB_Yb0 v] [http://www.wired.com/2016/03/hendo-2-hoverboard/ e] come to pass before reaching the date from the movie, but are more uncommon in our world, along with other inventions like [http://www.terrafugia.com/ flying] [https://www.youtube.com/watch?v=7-1pXbW5wVg cars] and [http://www.soundandvision.com/content/wear-your-music-thinkgeeks-soundtrack-shirt#jo8J1DassbWxlptj.97 musical clothing]. Randall is known to have had [[:Category:Electric skateboard|electric skateboards]], which is also thematically related, although another type of hoverboard would be mentioned just five weeks later in [[1623: 2016 Conversation Guide]].

With Randall's enjoyment with movies and time travels it is very likely that this game is also a tribute to the {{w|Back to the Future}} movies. But the release day of the game has been used to promote his new book (as is clear with the text in the start screen of the game), and this explains why it was not released on the Back to the Future date. Apart from the date of release and the text about the book, the game does not seem to have any direct relation to the book, there are, however, several scenes in the game that could be seen as [[#Reference to Thing Explainer|reference to ''Thing Explainer'']]. Instead the main part of the game is all the references to several movies and other stuff and that has often been featured in xkcd as well as many of the other comics.

===The game feature===
The game features an {{w|animated}} [[Cueball]] riding on a hoverboard which can take up [[#Animation|several different positions]]. The controls are the left, up, and right arrows as written on the start screen until you begin the game, then the text disappears. But there are alternatives as explained in the [[#Controls|Controls]] section. The player can jump repeatedly mid-jump to reach increasing heights, and can move left and right both while jumping and descending (see more under controls).

The player begins in a line-drawing maze (called the [http://www.explainxkcd.com/wiki/images/a/a9/All_play_area_hanging_all_coins.PNG Play Area]) with 17 gold coins located throughout and a "deposit" terminal. The ostensible goal of the game is to collect as many coins as possible and return them to the deposit in the fastest possible time, which returns [[#Messages in Play Area|text messages]] describing the result. Players consumed with obtaining the best possible time result for collecting the coins may not realize there is anything more to the game.

The best way to enjoy this comic is to {{xkcd|1608|play the game!}} If you didn't do that already, '''reading any below''' will spoil you from truly enjoying the comic, and maybe make some interesting discoveries yourself! So here is a '''spoiler alert''' if you read on.

Beyond the maze on either side (just far enough that players who remain within the maze will not see) are [http://www.explainxkcd.com/wiki/images/8/8b/1680_Play_Area_Full_Size_Coins_Hoverboard_and_View.png tall walls seemingly designed to contain the player]. However, the walls have a finite height and, combined with the ability to multi-jump, the player can leave the purported "play area" either to the sides or above the initial maze. This returns a flashing red [[#Messages in Play Area|error message]]: "'''[http://www.explainxkcd.com/wiki/images/a/ae/Return_to_the_play_area.PNG Return to the Play Area]'''".

But if the player overcomes the desire to comply and return to the play area, and disregard this message he can take hoverboard Cueball outside beyond the tall walls surrounding the initial play area. And here he will discover an entire world that can be explored left and right (and above), including numerous points of interest and {{w|Easter egg (media)|Easter eggs}} similar in style to comic [[1110: Click and Drag]]. There are also many more [[#Coins|coins]] to collect, 169 coins all in all, so 152 more than those from the play area.

Although this game is reminiscent of Click and Drag, this was the first time an actual game, where the user moves an object in front of the drawing, has been released on xkcd. In previous "games" this has not been the case. In Click and Drag the user "only" moves the drawing into the view section. And in for instance the two previous [[:Category:April fools' comics|April fools' comics]], [[1350: Lorenz]] and [[1506: xkcloud]], the user does not move anything, but only supplies choices, text and drawings. However, already on the next {{w|April Fools' Day}} a new game, [[1663: Garden]], were released where the users also actively moved items around on the screen and could make items disappear (like taking coins in this game.)

===The main themes===
There are many themes and references throughout the game, but the two main themes are '''{{w|Star Wars}}''' and '''{{w|The Lord of the Rings}}'''. Below there is a [[#List of details and references|table]] listing all references to both of these movies and much more. For instance there are 19 references to SW and 6 to LOTR.

The largest part of the game is located on the '''right side''' of the play area and is mainly a world dominated by references to ''Star Wars''. Most noticeable is a recreation of [https://youtu.be/yHfLyMAHrQE?t=112 the opening scene] in the {{w|Star Wars (film)|first film}}, where {{w|Princess Leia|Princess Leia's}} space ship ''{{w|Tantive IV}}'' also known as ''[http://www.explainxkcd.com/wiki/images/8/82/1608_1015x1078y_Entire_Rebel_Blockade_Runner_zoom_out.png The Rebel Blockade Runner]'' is flying over [http://www.explainxkcd.com/wiki/images/3/33/1608_1015x1073y_Ponytail_in_the_dunes_zoom_out.png the desert] planet {{w|Tatooine}}. Here it is followed by the {{w|Star Destroyer}}, ''[http://starwars.wikia.com/wiki/Devastator Devastator]''. The [http://www.explainxkcd.com/wiki/images/0/04/1608_1015x1078y_Entire_Rebbel_Blockade_Runner_zoom_out_to_torpedoes_and_ground.png desert ground with these two space ships] above is the first you find to the right. Although in the game they are located inside the atmosphere, not as in the movie out in space, a fact that is [http://www.explainxkcd.com/wiki/images/1/1d/1608_1049x1090y_Atmosphere_worry_and_car_room_at_bottom_of_hull.png commented on] by [[Megan]] who looks out from an opening in the bottom of the Destroyers hull.
:Megan: Is this ship designed to fly in the atmosphere like this?

Both ships are high above the ground level, but there are three [http://www.explainxkcd.com/wiki/images/7/76/1608_1014x1076y_Entire_wires_from_ground_to_Runner.png wires from the ground] that connect (and thus guide you) up to ''The Runner'' and from there [http://www.explainxkcd.com/wiki/images/8/87/1608_1023x1085y_Entire_torpedoes_rain_from_Runner_to_Destroyer.png 100+ torpedoes], which are fired [http://www.explainxkcd.com/wiki/images/f/f1/1608_1018x1079y_Top_rear_end_of_the_Rebel_Blockade_Runner.png down on the Runner] coming [http://www.explainxkcd.com/wiki/images/5/5f/1608_1034x1091y_Torpedo_canon_below_Destroyer.png from the Destroyer] above, gives away the location of the Destroyer itself. The Destroyer is so high up in the air, that you would not be likely to find it by chance without these leads (or at least some of the several other hints from people on the ground [http://www.explainxkcd.com/wiki/images/f/f2/1608_1010x1073y_Cliff_with_rock_and_cactus.png looking up and reacting] or like [[White Hat]] looking from the tip of the [http://www.explainxkcd.com/wiki/images/2/21/1608_0995x1079y_Entire_Washington_monument_extra_zoom_out.png Washington Monument] and reacting [http://www.explainxkcd.com/wiki/images/6/6f/1608_0995x1083y_Tip_of_Washington_monument.png by saying]: "Uh, what the heck is ''that?!''.").

One of the main points (The Joke) of the entire game is the extreme size of [http://www.explainxkcd.com/wiki/images/c/cd/1608_Entire_Star_Destroyer.png such a Destroyer]. It takes up more space than the rest of the game (and most of the coins is located there). Inside the Destroyer there are many many rooms, long corridors and deep shafts, even a [http://www.explainxkcd.com/wiki/images/5/58/1608_Entire_Cave.png huge cave] with trees and animals. At [http://www.explainxkcd.com/wiki/images/c/c7/1608_Vader_twice_and_emperor_on_and_near_bridge.png the bridge] we meet both {{w|Darth Vader}} and the Emperor himself, {{w|Palpatine}}. There are many other jokes related both to Star Wars and other movies and xkcd comics inside the Destroyer. For instance Darth Vader discusses Steven's mom from {{w|Steven Universe}} and [http://www.explainxkcd.com/wiki/images/3/39/1608_1031x1095y_Steven_Universe_family_and_ice_cream_prediction.png Steven himself], with family can be found in a different part of the Destroyer.
:Darth Vader: But Steven's ''mother'' is a crystal gem...
There are also interesting things and references along the ground beneath the Destroyer, some of these are also Star Wars related like [http://www.explainxkcd.com/wiki/images/c/c9/1608_1038x1073y_Wedding_and_picnic.png the wedding scene] where {{w|Jabba the Hutt}} is mentioned.

To the '''left side''' is an entirely different world, although much smaller (shorter) than the one to the right. Here the main theme is ''The Lord of the Rings'' mainly with the presence of a [http://www.explainxkcd.com/wiki/images/6/6a/Entire_Volcano_zoom_out.png volcano] where for instance [http://www.explainxkcd.com/wiki/images/7/77/1608_0952x1087y_Ring_of_power_and_lave_floor_at_the_right_crater_top.png Megan tries to throw] in {{w|One Ring|''rings'' of power}}, as in [https://www.youtube.com/watch?v=FXpF3SUFaDw the scene] from the {{w|The Lord of the Rings: The Return of the King|last LOTR film}} where {{w|Frodo Baggins|Frodo}} fails and {{w|Gollum}} attacks inside the volcano {{w|Mount Doom}}, thus making it clear that the volcano in the game represents this volcano. Both Frodo, {{w|Sauron}} and {{w|Gandalf}} are mentioned in the game. The first two by name in the text. Two {{w|Eagle (Middle-earth)|great eagles}} are [http://www.explainxkcd.com/wiki/images/c/cb/1608_0956x1088y_Eagles_over_right_crater_top.png talking about Frodo] and {{w|J. R. R. Tolkien|Tolkien}}, Sauron's name is [http://www.explainxkcd.com/wiki/images/6/66/1608_0964x1078y_Megan_reading_for_children_about_Saurons_ring.png read up by Megan from a book], and [http://www.explainxkcd.com/wiki/images/a/a5/1608_0944x1083y_Rock_with_Gandalf_in_Lava_lake.png Gandalf is drawn as a wizard figure] in the crater and also his name is used in the [[#Messages in Play Area|message]] you receive if you collect [http://www.explainxkcd.com/wiki/images/f/f7/169_coins_fastest_way.PNG all possible coins].

The two worlds do conflict though, as an {{w|X-wing fighter}} is [http://www.explainxkcd.com/wiki/images/4/44/1608_0982x1077y_Gas_station_with_x-wing.png parked at a gas station] to the left in LOTR world, and Gandalf's famous quote ''You shall not pass!'' from his fight against the {{w|Balrog}} is modified by [[Cueball]] who is [http://www.explainxkcd.com/wiki/images/a/ad/1608_1026x1093y_Shall_not_not_pass_room_and_parachutes_at_one_of_two_ledges_at_bottom_of_hull.png ''not'' trying to block your path] to a coin inside a room in the Destroyer. This conflict could very well be a reference to the fact that {{w|Andy Serkis}} who played {{w|Gollum}} in LOTR, now plays the {{w|Supreme Leader Snoke}} in the new Star Wars movie, and [http://vignette3.wikia.nocookie.net/villains/images/6/64/Supremeleader.png/revision/latest/scale-to-width-down/270?cb=20151223201852 his appearance] as Snoke is not that much different from Gollum's. Snoke also delivers a line in the movie (about "bringing someone to me") that reminds allot of Gollum when he talks about "the ring coming to me". Of course Randall would not have know this last part at the time this comic were released. But he would likely be aware of Andy Serkis involvement.

Other themes are related to other movies, like a [http://www.telegraph.co.uk/film/star-wars-the-force-awakens/star-trek-fans-rivalry-george-lucas-roddenberry/ naughty reference] to {{w|Star Trek}} from inside [http://www.explainxkcd.com/wiki/images/b/bc/1608_1012x1078y_Bridge_on_the_Rebel_Blockade_Runner.png the bridge] of the Rebel Blockade Runner where a long-haired woman (maybe [[Danish]] since she obviously does this to annoy Star Wars fans and [[Hairbun]] behind her, which could represent Princess Leia with her [https://upload.wikimedia.org/wikipedia/en/1/1b/Princess_Leia%27s_characteristic_hairstyle.jpg special hair style]) delivers the following line taken from the Star Trek universe:
:Long haired woman: Captain's log, stardate November 24th, 2015...
:Hairbun: ''Augh!'' No!

Also references to video games are seen, best shown with the maze towards the back end of the Destroyer which are an almost [http://www.explainxkcd.com/wiki/images/e/e2/1608_Comparing_Prince_of_Persia_maze_with_real_level_1.png complete depiction] of ''[http://cdn.wikimg.net/strategywiki/images/a/a2/Princeofpersia_dos_level1.png Level 1]'' of the computer game ''{{w|Prince of Persia}}'' down to the three coins being in the place of three items to take in that game, and at least two of the opposing sword fighters in the correct places as well.

The comic/game and book were released only 3 weeks before the 7th Star Wars movie ''{{w|Star Wars: The Force Awakens}}'' was released on December 14, 2015. And this movie had already been referenced by Randall 7½ weeks earlier in [[1585: Similarities]], when another movie ({{w|The Martian (film)|The Martian}}) were released. It was a reference in the title text to the new robot ''BB-8'' that are featured in the Force Awakens. That the Star Wars section is thus so much larger than the LOTR section could be a hint to the fact that it is now 12 years ago that the last of those films were released, and although {{w|the Hobbit}} has been released as {{w|The Hobbit (film series)|three films}} over the previous three Christmases it was Star Wars that dominated the Christmas a month after this comics release.

===Reference to Thing Explainer===
Some of the scenes in this game are references to pictures in the new book that it celebrates. Here are some examples:
*The original comic, that was the cause of ''[[Thing Explainer]]'' in the first place, [[1133: Up Goer Five]] is also included in the book. And these are thus both referenced in this game by the [http://www.explainxkcd.com/wiki/images/e/e2/1608_0976x1079y_Space_capsule_with_parachutes.png space capsule] used for reentry by the astronauts that flew to the moon using the {{w|Saturn V|Saturn Five}} rocket. This capsule is floating down over the plateau before the volcano to the left.
*In ''Sky Toucher'', the last entry explaining a sky scraper, there are several references to the game, one of these being the space capsule just mentioned above. Other references:
**Ponytail throwing a paper plane out, which she also does [http://www.explainxkcd.com/wiki/images/2/20/1608_1077x1107y_Tarkin_on_the_bridge_and_Ponytail_with_paper_plane.png below the bridge] of the Destroyer. (This is also a reference to ''Click and Drag'' where [http://imgs.xkcd.com/clickdrag/6n2w.png Cueball does the same], here even from a skyscraper).
**Cueball is setting up a kite and Ponytail is crawling up in the line. In the comic a small girl looking like Megan [http://www.explainxkcd.com/wiki/images/a/ae/1608_0970x1077y_Kite_and_weird_bug.png also has a kite]. Being up in a kite is also referenced in both [[235: Kite]] and in the title text of [[1614: Kites]] (from just a few weeks after the release of this comic.)
**There is a floor in the middle of the building with trees, just like there is a cave inside the Destroyer [http://www.explainxkcd.com/wiki/images/7/75/1608_1053x1093y_Lake_with_tree_birds_and_puma_on_rock_at_exit_in_the_bottom_left_side_of_the_cave.png with a tree "inside"].
**Cueball is holding a fishing rod out over the side of the building letting the hook hand in the air. The same [http://www.explainxkcd.com/wiki/images/5/58/1608_1014x1078y_Three_wires_and_reaching_up_to_anchors_in_Runner.png can be seen] under the Rebel Blockage Runner.
**Megan is using a skateboard in a strange ellipsoid-shaped room. This can be a reference both to where Megan is seen on a [http://www.explainxkcd.com/wiki/images/8/89/1608_1038x1095y_Hamsterball_and_stilts_room.png skate board inside a hamster ball] and to the [http://www.explainxkcd.com/wiki/images/7/7b/1608_1078x1111y_Globe_of_Death_at_the_top_of_the_Destroyer.png globe of death] at the top of the bridge on the Destroyer.
**There is a car in the top section of the tower (long away from the parking cellar in the basement). There are two [http://www.explainxkcd.com/wiki/images/1/1d/1608_1049x1090y_Atmosphere_worry_and_car_room_at_bottom_of_hull.png cars inside] the Destroyer, [http://www.explainxkcd.com/wiki/images/d/d4/1608_1048x1099y_Cueball_on_hood_of_car_room_and_a_giant_step_with_coins_at_top_of_hull.png one of them] deep inside with no easy access to the outside.
**Two people are standing on a cloud, one of them (Megan) jumps out from it. This is similar to the [http://www.explainxkcd.com/wiki/images/9/92/1608_0993x1112y_Top_of_floating_rock_island_with_base_jumpers.png two base jumpers] on the [http://www.explainxkcd.com/wiki/images/5/5c/1608_0994x1110y_Entire_floating_rock_island_zoom_out.png rock island].
*In the ''Red world space car'' explaining (about the {{w|Curiosity Rover}} on {{w|Mars}}) there are two references to the scenes around the Rebel Blockade Runner:
**Curiosity toasts a marshmallow over a fire as does Megan and Cueball over the exhaust pipe at [http://www.explainxkcd.com/wiki/images/f/f1/1608_1018x1079y_Top_rear_end_of_the_Rebel_Blockade_Runner.png the rear of the Runner].
**When Curiosity is set down on Mars by the {{w|Mars Science Laboratory}} (MSL), lowered down in wires below the MSL, the wires were released once the rover was down and then it flies away. In the book Megan is hanging from one of these wires when it flies away. This is similar to [http://www.explainxkcd.com/wiki/images/7/76/1608_1014x1076y_Entire_wires_from_ground_to_Runner.png Megan hanging in one of the anchor lines] going from the ground up to the Runner.
*In ''The USS Laws of the Land'' about the ship called {{w|USS Constitution}} (named after {{w|United States Constitution}} which is explained in the entry just before this one), there are two references to this comic:
**There is both a giant octopus arm (marked as ''not real'') and a very large octopus under the ship. The shape of the octopus is the same as the [http://www.explainxkcd.com/wiki/images/b/b5/1608_1038x1094y_Giant_octopus_in_Destroyer.png silhouette of a giant octopus] inside the Destroyer.
***Octopuses like this is often used in xkcd, and they are also included in the explanation about ''Writing sticks'' (as the source of ink for the pens), as a motive in ''Picture taker'' and in ''Tree of life''. As an example from another xkcd comic with octopuses see for instance [[435: Purity]].
**There is also a bowling alley in the hull of the ship - a reference to the [http://www.explainxkcd.com/wiki/images/5/53/1608_0987x1075y_Hamsterball_bowling.png hamster ball bowling] in the left part of the world.
***Bowling is also used two other places in the book, namely on the suspension of the longest bridge in ''Tall roads'' and an bowling alley is used for measuring length in ''How to count things''.
*Ants are used three times in the book. A zoom in on an ant is used to indicate size in ''Earth's past'' about geological ages of the Earth, and under the ''Tree'' in that explanation there is an ant colony where one ant is much bigger than the others; an ant queen, a clear reference to the [http://www.explainxkcd.com/wiki/images/d/d2/1608_1078x1095y_Ant_Queen_in_Destroyer.png ant queen] in the Destroyer. They are of course also in the ''Tree of life''.
*Basketball is shown twice in this comic ([http://www.explainxkcd.com/wiki/images/a/a4/1608_0936x1084y_Basketball_on_the_volcano.png left of volcano] and [http://www.explainxkcd.com/wiki/images/1/1d/1608_1067x1104y_Basket_ball_on_top_of_Destroyer.png on top of Destroyer]). In the book the size of different ''Playing Fields'' is one of the stories, and it included the field for basketball (i.e. ''circle ball'').
*The [http://www.explainxkcd.com/wiki/images/d/d0/1608_1046x1074y_Huge_foot.png huge foot] before the pyramid look like the foot used in the explanation for ''How to count things'' to describe the wight "one kilo" using a picture labeled ''one foot'' (i.e. not the length one foot, as the length is given in meters). A similar experience to the one in [[526: Converting to Metric]].
*The [http://www.explainxkcd.com/wiki/images/d/d2/1608_1084x1090y_Giant_light_bulb_room.png giant light bulb] towards the bottom rear end of the Destroyer is a reference to the entry on {{w|tungsten}} in the explanation for ''The pieces everything is made of'' (i.e. the {{w|periodic table}}). In the book a {{w|Incandescent_light_bulb|light bulb}} is shown and then an arrow points to the {{w|Incandescent_light_bulb#Filament|filament}} which is made of tungsten in the typical {{w|Thomas Edison|Edison}} light bulbs.
*In the explanation for ''Box that cleans food holders'' (Dishwasher) Ponytail yells ''Wheee!'' as she slides through a pipe inside the machine on her stomach (bottom left). This is similar to her position and movement in the [http://www.explainxkcd.com/wiki/images/c/c6/1608_Entire_Corridor_peristalsis_and_colon.png colon like structure] inside the Destroyer and Cueball also sliding in this colon yells ''Wheee!''
*In the explanation for ''Bending computer'' Ponytail comes racing on her bike with a laptop on top of the handlebars. She is also seen [http://www.explainxkcd.com/wiki/images/c/cd/1608_0958x1083y_Ponytail_racing_down_the_steep_slope_on_a_bike.png racing a bike down the slope of the volcano].

===Reference to other comics===
There are also many references to other xkcd comics, like the room at the front end of the Destroyer [http://www.explainxkcd.com/wiki/images/a/a7/1608_1004x1095y_Very_front_with_playpen_balls_pit_at_top_of_hull.png ball pit] filled with '''[[:Category:Playpen balls|playpen balls]]''', and two adults playing in it, like in [[150: Grownups]]. Also [http://www.explainxkcd.com/wiki/images/2/2e/1608_0980x1075y_Entire_well_zoom_out.png the well] in the left part of the world with [http://www.explainxkcd.com/wiki/images/8/82/1608_0980x1073y_Well_bottom.png a girl and a coin] at the bottom is likely a reference to the movie ''The Ring'', which has been referenced before in xkcd. Wells have also come up in xkcd in the early '''[[:Category:Well|Well series]]'''.

There have been many comics with electric skateboards as mentioned, which do not appear in this comic, but there is one example of a normal '''skateboard'''. This is [http://www.explainxkcd.com/wiki/images/8/89/1608_1038x1095y_Hamsterball_and_stilts_room.png used by Megan] in a room in the Destroyer, while she is inside a {{w|hamster ball}}. There is also [http://www.explainxkcd.com/wiki/images/5/53/1608_0987x1075y_Hamsterball_bowling.png another hamster ball], with a kid (looking like Megan) inside. It is used in a more than human sized {{w|ten pin bowling}} game to the left. '''Hamster balls''' is another item that has been [[:Category:Hamster Ball|prominently featured]] in xkcd.

In the weeks before, and especially the weeks after there were also other comics that had a subject which could refer back to Hoverboard in some ways. Maybe these comics were either influenced by the game, or the other way around so that relevant items were added to the game because of these other comics:
*[[1600: MarketWatch]] - the {{w|Washington Monument}} (an obelisk) is part of the skyline depicted, and this monument is the [http://www.explainxkcd.com/wiki/images/2/21/1608_0995x1079y_Entire_Washington_monument_extra_zoom_out.png first that is encountered] in the picture when going left from the play area, plus a [http://www.explainxkcd.com/wiki/images/d/dc/1608_0994x1074y_Base_of_Washington_monument.png comment at the base] of the monument to make sure we know it is the Washington monument, and another [http://www.explainxkcd.com/wiki/images/6/6f/1608_0995x1083y_Tip_of_Washington_monument.png comment at the top] of the monument referring to the {{w|Washington_Monument#Aluminum_apex|aluminum apex}} that constitutes the very tip of the monument, which was very expensive at the time it was installed in 1884, when aluminum was a rare metal as valuable as silver. Today it would not make anyone rich from the metal alone, although the tip would be worth a lot for other historical reasons, but this is not what Cueball's comment is about.

**See also [[1641: Hot Dogs]] where Cueball has a similar style conversation, with the same ''Eww'' ending as with the ant queen:

*[[1611: Baking Soda and Vinegar]] - this is about super volcanoes, vs. [http://www.explainxkcd.com/wiki/images/6/6a/Entire_Volcano_zoom_out.png the Volcano], Mount Doom in the game as indicated by Megan [http://www.explainxkcd.com/wiki/images/7/77/1608_0952x1087y_Ring_of_power_and_lave_floor_at_the_right_crater_top.png throwing rings into the lava]:

===Characters===
Almost all main [[:Category:Characters|characters]] in the xkcd gallery are used more than once, especially there are three characters that are used several times. Number one is of course [[Cueball]] (with close to 90 appearances) who is already shown at the [http://www.explainxkcd.com/wiki/images/6/6c/1608_1000x1074y_The_Play_Area.png starting point]. He is also the first character seen when walking both [http://www.explainxkcd.com/wiki/images/c/c0/1608_1004x1074y_Cueball_outside_play_area.png right] and [http://www.explainxkcd.com/wiki/images/d/dc/1608_0994x1074y_Base_of_Washington_monument.png left] (where he speaks the first line to the left).

Then follows [[Megan]] with at least 40 appearances, she is even shown twice in the same location three times, one of these three even occurs within one of the [http://xkcd.com/1608/1090:-1088+s.png small images]. She is also shown with Cueball in his first appearance to the left, and she is the first to speak a line to the right [http://www.explainxkcd.com/wiki/images/f/f2/1608_1010x1073y_Cliff_with_rock_and_cactus.png here].

Also [[Ponytail]] is well represented with 26 appearances (for instance [http://www.explainxkcd.com/wiki/images/2/2d/1608_0947x1073y_Antenna_cave_in_lair.png here)].

[[Hairy]] (with different hair styles) is used 7 times (for instance [http://www.explainxkcd.com/wiki/images/5/54/1608_Actual_Bridge_with_Vader_and_Tarkin.png here]) and [[Hairbun]] is used 5 times (for instance [http://www.explainxkcd.com/wiki/images/e/e4/1608_1054x1099y_Corridor_peristalsis_and_two_coin_rooms_at_top_of_hull.png here)].

Two of the main characters are used twice: [[Beret Guy]] ([http://www.explainxkcd.com/wiki/images/4/4f/1608_0990x1074y_If_loving_you_is_wrong_I_dont_want_to.png here] and [http://www.explainxkcd.com/wiki/images/2/21/1608_1020x1083y_Torpedoes_two_steps_above_Runner_with_Beret_Guy.png here]) and [[White Hat]] ([http://www.explainxkcd.com/wiki/images/6/6f/1608_0995x1083y_Tip_of_Washington_monument.png here] and [http://www.explainxkcd.com/wiki/images/d/d9/1608_1093x1074y_White_Hat_hiding_in_the_grass.png here]).

The only exception is that the main villain of xkcd [[Black Hat]] who is very hard to find. He is only [http://www.explainxkcd.com/wiki/images/6/68/1608_1069x1093y_Deer_and_exit_below_lamp_coin_and_Black_Hat_in_the_bottom_right_side_of_the_cave.png shown once] in the comic where he very uncharacteristically just sits and snores at the right wall in the cave inside the Destroyer (is it really him...?). The only other hint that he is not forgotten is that his hat can be seen [http://www.explainxkcd.com/wiki/images/b/bc/1608_1073x1074y_Ponytail_and_bird_black_hat_on_a_stick_and_Cueball_whistling.png on a stick] under the Destroyer after the three large T-like structures. And this is not that kind of stick characters Randall usually draws. But at least we now know where Danish has hidden it from him this time (see [[405: Journal 3]]). Given that his hat is stuck there, he could also be any of the Cueballs close by…

There are also several characters that are not recognizable as either any of the standard xkcd characters or in any other way (see for instance a few of the [http://www.explainxkcd.com/wiki/images/a/a6/1037x1073y_Wedding.png wedding guests]). But there are possibly some of the minor characters are used like [[Danish]] at the bridge in the Blockade Runner ([http://www.explainxkcd.com/wiki/images/b/bc/1608_1012x1078y_Bridge_on_the_Rebel_Blockade_Runner.png here]) and [[Miss Lenhart]] discovering a bug before the volcano ([http://www.explainxkcd.com/wiki/images/a/ae/1608_0970x1077y_Kite_and_weird_bug.png here]). But neither of these can be confirmed, they just looks like them and has some similarities, like “Danish” teasing the Star Wars fan and Lenhart in some kind of teacher mode.

Several places in the comic it is clear from the size and the behavior that some of the characters are kids, see for instance the Miss Lenhart image mentioned above, where two kids looking like Megan and Hairy stand behind her, but they would in principle not be the Megan or the Hairy despite appearance, as the named characters are adults.

There are also many fictive people from different movies, books and TV-shows; for instance Darth Vader ([http://www.explainxkcd.com/wiki/images/f/fa/1608_1077x1109y_Darth_Vaders_talks_about_Steven_Universe_on_the_bridge_Megan_adjust_antenna.png here]), Gandalf ([http://www.explainxkcd.com/wiki/images/a/a5/1608_0944x1083y_Rock_with_Gandalf_in_Lava_lake.png here]) and Steven Universe ([http://www.explainxkcd.com/wiki/images/3/39/1608_1031x1095y_Steven_Universe_family_and_ice_cream_prediction.png here]) all three mentioned above, and at least one real person: {{w|Elon Musk|Elon Musk}} who has a [[#Secret passages and hidden places|hidden lair]] under the Volcano (see [http://www.explainxkcd.com/wiki/images/7/73/1608_0945x1074y_Elon_Musks_cave_in_lair.png here]).

Furthermore, there are many animals (like [http://www.explainxkcd.com/wiki/images/b/b0/1608_1067x1094y_Gazebo_puma_deer_Cueball_with_bow_and_talk_of_Palpatine_in_the_middle_of_the_cave.png the puma and the deer]) in the cave, some even rather big like this [http://www.explainxkcd.com/wiki/images/b/b5/1608_1038x1094y_Giant_octopus_in_Destroyer.png octopus] or even gigantic like this [http://www.explainxkcd.com/wiki/images/d/d2/1608_1078x1095y_Ant_Queen_in_Destroyer.png ant queen] (all three from inside the Destroyer). There are also a couple of small Star Wars robots, one in a corridor in each space ship ([http://www.explainxkcd.com/wiki/images/d/df/1608_1034x1091y_Photon_canon_Tetris_piece_and_mini_robot_at_bottom_of_hull.png here from the Destroyer]).

===Extra Hoverboard pages===
*Since this comic is so big and complicated extra pages have been created to include much more information than is wished for on this main page (which is already of considerable size).
*These pages are listed here for convenience, but they are also listed in the relevant sections below:

==Transcript==
:[This transcript only covers the starting page as shown on xkcd: {{xkcd|1608}}. A full transcript of the entire comic can be found on this [[1608: Hoverboard/Transcript|page]].]


:[Cueball is shown on a hoverboard in the center of the comic. Around him is a simple maze with 12 yellow coins. Another Cueball without hoverboard is shown standing on one of the platforms to the right. The bottom half of the window is black. Right of where Cueball stands is a ramp. Behind the ramp is a terminal. There is lots of space left of the maze, outside the maze. Text is only written in white below in the black area. The first part of the text is written below Cueball on hoverboard. Then there is an arrow pointing to the terminal and a label. Finally there is a line of text at the bottom of the black area.]

:[Under Cueball:]
:My new book,
:''Thing Explainer,''
:comes out today!
:To celebrate, here's
:a small game.

:[Under the arrow below the terminal.]
:Deposit coins here

==Trivia==
*There is as usual [[:Category:No title text|no title text]] for these interactive comics. But there is actually one listed in the [http://xkcd.com/1608/info.0.json info page] on xkcd. But this text: "Return to the play area", is never shown as a normal title text. But it will erroneously be shown in the unofficial mobile versions of the site.
**This is actually the [[#Messages in Play Area|text that is shown blinking red]] at the bottom of the screen when leaving the Play Area.

'''''Warning:''' apart from using one of the a full maps below there are also other [[#Cheats and Exploits|cheating possibilities]] where people (or the game) have implemented ways to explore the game world more easily!. The best way to enjoy this comic, however, is to play the game, explore the comic's world the way you're supposed to, get lost in the caves or in the sky, be startled by unexpected things or happy when finding some people or a coin after lengthy exploration through a repetitive landscape. If you didn't do that already, '''reading any below will spoil you from truly enjoying the comic.''''' So go back to the link above and try that out first.

==Messages in Play Area==
*Different amounts of coins collected in the play area, will give different messages in yellow on the black part at the bottom of the screen when delivered to the coin collector.
*Below is a table with examples of what may be written depending on the number of coins. The time (and the amount when there is a range with similar rating) is just chosen at random (although in a realistic range). To get above 17 you of course have to leave the play area and come back again...
**In Chrome and Firefox there is not message for those above 9 coins, except 17, 42 and 169. But in Internet Explorer there is still a message for those cases: "Undefined".
**See [[1608: Hoverboard/Screen-shots#Coin collecting messages|screen-shots]] or click on the links from the number of coins in the table below:

*Once you leave the area you get a [http://www.explainxkcd.com/wiki/images/a/ae/Return_to_the_play_area.PNG flashing warning message] in red letters at the bottom of the screen:
:{| class="wikitable"
|style="background-color:black;"| '''Return to the play area'''
|}
*This message flashes three times over 1.2 seconds (the message only disappears for about 150 ms each time)
*Then there is a pause for about 1.3 seconds and then this repeats for a total of 5 repetitions, a total of 15 flashes in just about 11.3 second seconds.
*The message will stop immediately if you re-enter the play area during this period.
*If you re-enter later it will flash once you leave again.
*For the program the play area is anything within and below the walls just outside the maze you start in.
**More precisely you first leave the play area if you pass over the middle part at the top of the walls
**Or if you make one jump from standing on top of the walls.

==Animation==
*There have before been several interactive comics and also a few with animations. But these animations have typical been something along the lines of flashing text or changing lights.
**This comic is the first with a character that is specifically changing position in animation style.
**Apart from this there are also flashing text when leaving the play-area and text that appears and disappears when handing in coins at the terminal as described above under [[#Messages in Play Area|Messages in Play Area]].
**This also happens with the text written to begin with explaining how to play the game: ''Use the arrow keys to move'' which disappears when touching the keys.
*Here are two images showing two kinds of animation of the hoverboard Cueball.
**The first image shows the eight standard animation that can easily be seen. They are
***Standing still facing right (starting position)
***Standing still facing left
***Moving left along flat ground (lifting arms)
***Moving right along flat ground (lifting arms)
***Jumping while facing left looking up with hoverboard pointing down
***Jumping while facing right looking up with hoverboard pointing down
***Falling while facing left looking down with hoverboard pointing up
***Falling while facing right looking down with hoverboard pointing up
[[File:1608 Hoverboard Cueball standard animation.png]]
*But there are several in between drawings of the hoverboard Cueball turning from left to right and even more from right to left.
**The second image shows eight in between animations (together with four from above)-
**Not all possible positions are necessarily caught in this collage here, but there is only a limited amount of them and none of them last for more than a split second.
**They have been sorted so it could look like Cueball has just turned to the right standing still, then jumping while turning right, then turning right while in jump, to finish the turn while falling.
**Image 2, 3, 5 and the last are the same used in the image of standard animations

==Secret passages and hidden places==
There are many places where you can disappear behind black areas, as not all of these are solid. Some of these places even hide secret passages or hidden rooms.

One notable hidden area is {{w|Elon Musk|Elon Musk's}} volcano lair, which is located beneath the lava in the crater of Mount Doom. It can be difficult to find your way in here even if you know it is there. (For more details, see [[1608: Hoverboard/Images of secret passages|secret passages]].)

Another hidden place is the floating rock island that floats high above the {{w|Washington Monument}}, which is located just outside the left edge of the play area. This island is almost impossible to find by chance, as it takes around 30 seconds of repeatedly pressing the Up Arrow key to reach it from the top of the Monument. (The [[#Viewers|maps]] can help you if you're having trouble finding it.)

As there are two coins on the floating rock island and four coins in the lair below the lava, it is very hard to find all the coins. There are even several coins that are hard to find because they just float in the air nowhere near any drawn things, or at least no things you can see before seeing the coin. They may hang in the air a few jumps above the ground, or in one case more than a seconds drop below the Destroyer. So getting all coins without help from a map would truly make you a [http://www.explainxkcd.com/wiki/images/f/f7/169_coins_fastest_way.PNG Gandalf-like wizard]. (See more regarding [[#Coins|coins]] below.)

==Boundaries==
The larger game world is physically bounded in the left, right, and down directions, with invisible walls to each side and the ground binding you from going any further down than the deepest depression or hidden caves... In the upward direction, there is in principle also an invisible wall, but while jumping up Cueball on his hoverboard will appear to continue upwards as long as you press to jump, in addition, the longer the up arrow is pressed repeatedly, the longer it will take for [[Cueball]] to fall down again once the button is released. So although there are no new things above, you can keep jumping as high as you like and will then fall proportionally longer to get back to where you started out. Until maps were created it could be possible that there could be some hidden unexplored parts, but the [[#Viewers|maps]] created already within the first few days covers the entire game.

To the far right is a platform at the top of a high pole. This platform turns out to be a nest (like a stork nest). Above the three eggs are ten coins (the most collected in one place outside the play area, and these are closer together).

To the far left is a blond haired woman with a hair bun looking right. In front of her are four coins on a row. She tells about the Destroyer (should you have gone this way without finding it yet).
:Woman: In the sky, beyond the mountain, I saw a starship.

Regarding the highest part you find the highest straight rise up in the air to something other than white, under the Rock Island just left of and very high above the Washington monument. Standing on the large rock on top of this floating rock island you are standing almost as high up as possible. There is a coin here one step down from the top of this large rock. This is the highest located coin in the game. Going over the edge also represents the largest possible drop in the game. However this is not the highest point where you can stand, as the very top of the bridge on the Destroyer is just a tat higher. But there is no coin there. Also this is not close enough to the end of the Destroyer that you can jump down to the ground, so the drop from the rock is by far the longest possible.

The deepest part of the lair should have been the lowest point, but as this lair's entrance is up in the volcano crater, it does not reach down to become the lowest part of the image. There is also a deep well (half way left to the Volcano) with a girl at the bottom, that goes just as deep. But the deepest part where you can stand is in the ocean below the Destroyer where a rouge wave is talking to Cueball:
:Wave: I know rogue waves seem implausible, but we're a straightforward consequence of the equations of fluid dynamics.
:Cueball: ...But you can talk?
:Wave: The equations are really complicated.
When standing under this wave you cannot get any lower. There are coins in all three locations, but as the coin is above the top of the high wave, it may be that it is the coin in the well that is the deepest. The coin under the lava is not at the bottom of the room so that is not so low.

Taking a route that takes the hoverboard through all the extremes mentioned above, that is the lowest, highest, left and rightmost coins and solid positions within the game can be done in about 9 minutes and 30 seconds. See a picture here of the coin delivery after such a trip that [[1608: Hoverboard/Screen-shots#Reaching all the boundaries|reached all the boundaries]].

*Coordinates for the images are given in (X, Y) coordinates with the starting point at [http://xkcd.com/1608/1000:-1074+s.png (1000, 1074)].
*In total there are 3440 images on xkcd that can be accessed via links of this format: http://xkcd.com/1608/1000:-1074+s.png [This link is for the (1000, 1074) starting point image.]
**'''Here is a page with a table of all the links to images: [[1608: Hoverboard/All image links|All image links]].'''
**'''Note:''' This is a large page which may take some time to load.
*The individual images are so small, and cut of at "random" so they do often go straight down through a person, and you can rarely see both a person and the (full) text belonging to them in the same image.
**See for instance this [http://www.explainxkcd.com/wiki/images/a/a6/1037x1073y_Wedding.png wedding scene] to the right under the Destroyer, which only makes sense when these four images are put together (as they are in the link):
***[http://xkcd.com/1608/1037:-1073+s.png (1037, 1073)]
***[http://xkcd.com/1608/1037:-1074+s.png (1037, 1074)]
***[http://xkcd.com/1608/1038:-1073+s.png (1038, 1073)]
***[http://xkcd.com/1608/1038:-1074+s.png (1038, 1074)]
**It will thus not make sense to make a transcript of all individual images, but instead, only of a complete setting (or maybe a part of a setting.)
*Maximum possible number of images in the x-direction is 180.
**Going left will decrease X down to 928 (so 82 pictures left of the starting point in X-direction)
**Going right will increase X up to 1107 (so 107 pictures left of the starting point in X-direction)
*Total number of (possible) images in the y-direction is 44.
**Going down will decrease Y down to 1069 (so 5 pictures down from the starting point in Y-direction)
**Going up will increase Y up to 1112 (so 38 pictures up from the starting point in Y-direction)
***The "(possible)" is included because the number of possible active Y-images depends on the X-coordinate, as there are several non-existing images that are not just totally white (i.e. blank images), but which does not even have a number/or active link on xkcd.
***But the top active image over the floating island and over the top of the bridge section of the Destroyer all have Y coordinate 1112. There are only 20 active images at this Y-coordinate.
***The same by the way also goes for the x coordinate. Above X=1076 there are also many non existing images with not active link.
* All possible images are thus spread over a 180 x 44 grid, with a possible 7920 images. But 4480 of these images are non existing on xkcd, but you can travel through them in the game, as they are just shown as completely blank/white empty air in the game.
**If you try to load one of the completely blank images like [http://xkcd.com/1608/1000:-1077+s.png (1000, 1077)], three images above the starting point, you will get an error message. There are only 76 (vs 180) images at this Y-coordinate.
***Note there are several completely empty/white images that are active, but those can be loaded on xkcd like the one below the missing picture mentioned above: [http://xkcd.com/1608/1000:-1076+s.png (1000, 1076)].
**There are no blank images in completely black areas, like inside structures or under ground. And below Y = 1077 all 180 possible Y-images exist for all X-coordinates, from Y = 1069 to 1076.
***For instance the image below the starting point is completely black [http://xkcd.com/1608/1000:-1073+s.png (1000, 1073)], and so are the next three below.
***The bottom images at Y = 1069 has a white border at the bottom: [http://xkcd.com/1608/1000:-1069+s.png (1000, 1069)].
***All the images at Y = 1069 are the same except the one at the very right edge because at this edge there is also a white border to the right [http://xkcd.com/1608/1107:-1069+s.png (1107, 1069)] (this is not the case to the far left at [http://xkcd.com/1608/928:-1069+s.png (928, 1069)]).
***You will never see the images at Y = 1069 in the game. Actually you will neither see anything of the images with Y = 1070 or 1071. And there is nothing that is not completely black for Y = 1069 to 1072. First from Y = 1073 are there active images which includes white.
***This picture with the wave at [http://xkcd.com/1608/1022:-1073+s.png (1022, 1073)] gives the lowest point where the hoverboard Cueball can actually stand.
***Since you will sink into the water here, you are almost standing on the top of the Y = 1072 image: [http://xkcd.com/1608/1022:-1072+s.png (1022, 1072)], which is of course completely black.
***In places where you can stand in a low position on Y = 1073 images you will actually see some part of the images with Y = 1072, not that it makes any difference since they are all black.
*Here is a list of the places where there are most images at a given X coordinate:
**At X = 1078, right under the highest point of the Destroyers bridge [http://xkcd.com/1608/1078:-1112+s.png (1078, 1112)] there are 36 active images. Thus even here 8 images are missing between the bottom active image below the Destroyer and the first active near the ground level at Y=1076. (Y = 1077 to 1084 are missing).
**These missing Y coordinates are active in other places, for instance under the torpedo rain at X = 1020 where all Y images are active up until 1100 - 32 images. But since the last 12 images above this are missing it is still 4 less than under the bridge.
**Under the floating island, where there are active images at the top Y = 1112, like [http://xkcd.com/1608/990:-1112+s.png (990, 1112)], there is also the Washington monument below which goes high up, but still there are only 20 active Y images, as there are no active images between 1084 and 1109 (24 missing in between).
**Over the volcano's edges the highest images directly connecting to solid ground is found at Y = 1087. One image above this is also active making the height here going up to 1088, thus also making it 20 active Y images. The only '''not''' completely white image over the volcano at Y = 1088 is the one with the eagles [http://xkcd.com/1608/956:-1088+s.png (956, 1088)].

==Dimensions==
{{incomplete|Here should be an overview of how large the picture is (physical distances and time to traverse it. Speed of hoverboard etc.) Could be based on know monuments sizes.}}
*It takes 1 minute 52 s to reach from the starting point to the left edge

==List of details and references==

*On this page [[1608: Hoverboard/Images of individual scenes]], images covering all individual scenes (in full size and with coins) has been saved and uploaded to be used for reference in the [[#Table with references|table]] below from where they are linked directly.
**There are also several overviews in smaller resolution
**Almost all these images have been made using this [http://1101b.com/xkcd1608/ Fully zoomable map w/ toggleable coins and passages] which includes all of the game, zoom-able and with toggle-able passages and coins.

===Explanation of the table===
*The contents of the comic are documented in the [[#Table with references|table]] below.
**It first goes through the entire image from left to right along the ground
***I.e. going up the volcano and down in the lair, down the well and up to the top of the Washington Monument. Only exception so far is that it here goes to the rocky island in the sky. Then it continues right along the ground, only following the wires up to the bottom of the Rebel Runner and then after going over the pyramid it ends up at the far right
**Then it goes back to the Rebel Runner, and after that follows the torpedoes up to the Star Destroyer-
**Finally it goes through the Star Destroyer from tip to rear in four sections, taking everything within each section top to bottom, before moving on to the next section.
**The table can be sorted on all columns, so the above is only valid until any sorting takes place.
*In the table are the following columns:
**Descriptions of the scene depicted in the overview links.
***If the scene is a zoomed out overview that covers the images below this scene's description has been written in '''bold text'''.
***This can be used as a guide to where in the image the scenes are located.
***That is, until any sorting begins.
**Transcript.
***Any text has only been transcribed once. If some scenes overlap, the text has only been written in the first or the one where the text is most central.
***Also any overview that has been zoomed out never has any transcript - these have been listed as (N/A)
***Scenes with no text has written (None) in the transcript.
***The use of parenthesis for those with no transcript makes it possible to sort on the transcript to get all the scenes with text to the top.
**Overview links.
***There can be more than one, even many, but the first will always be the overview.
***If there are secret passages or other situations where it will be interesting to see why the hoverboard can disappear beneath the surface (like in the ocean) then two versions of the images have been included.
***The second version is called ''Hidden passages in red'' as it has these passages changed to appear in red instead of black.
**Tile images on xkcd.
***For those images that are zoomed to 100% (i.e. not the zoomed out overviews) there is also a link to the defining image tile on xkcd.
***In cases where there are more than one interesting image tile in one scene (maybe because there is actually two or more distinct scenes), there can be one more link in the ''Other'' tile column.
**References.
***Three things are referenced many times, and each has their own column so the table can be sorted on these
****SW: Star Wars
****LOTR: The Lord of the Rings
****TE: Thing Explainer
***Other. There is also a column for "other" types of references so they can also be sorted, without drowning in the three recurring types of references.
****These have some further sorting by starting with Comics: or Movies: etc.
**Explanations is in the last column.
***So far lots of scenes still miss explanations, and some are not complete.
***Red text has been used to make this clear.
***If updating this and making a good enough explanation delete the red text.

===Table with references===
*See [[#Explanation of the table|explanation of the table]] above.
**Hint: Open the overview links in a new window and return to this one for the next image and for reading the text.

|This is a reference to {{w|Pompeii}} a Roman town-city near modern Naples, which has become famous when it was discovered that it had been preserved in the ash when it was mostly destroyed and buried under 4 to 6 m (13 to 20 ft.) of volcanic ash in the eruption of {{w|Mount Vesuvius}} in AD 79. When it was {{w|Pompeii#Rediscovery|found again}} it turned out that people had been surprised by the ash, and thus buried alive. During the excavation, plaster was used to fill in the voids in the ash layers that once held human bodies. This allowed one to see the exact position the person was in when he or she died. This is what Ponytail wishes for her and Megan, when the volcano they are standing on erupts, a rather morbid wish. She wants their sweet basketball moves to be preserved for eternity. In ''Playing Fields'' in TE basketball is mentioned. It is also played on top of the Destroyer close to the bridge. In this case the coin is on top of the basket, but too large to go into the hoop.

|These images only cover the part beneath the surface where there is actually still lava, as can be seen in the images where ''Hidden passages in red''. Only the top of the lair below is shown here. From the hidden passage it is here possible to see how to enter this lair. In the images that shows the hidden part the two loose boulders that float (or are outcrops) in the right part of the lake can be seen as well as the two other holes in the lava lakes floor, which all explain why it is easy to get stuck in the lake once you go below the surface and move around. Since everything is black, you do not even know if the game still works and many people may have given up, maybe reloading after not being able to get on with the game. There is no place in the lake where you can get really stuck, as long as you just push upwards while changing direction from left to right, you are bound to get out sooner or later.

|The wizard on the rock represents Gandalf from LOTR. What Megan tells Cueball works fine with water, not so much with lava. The horse Artax (pronounced Artex in the film) [https://www.youtube.com/watch?v=y688upqmRXo drowns in the swamp of sadness] while Atreyu tries to save it and yells its name. Drowning in a swamp sucks, but doing so in lava will make death swifter. Both situations, however, indicate that you can actually go into the lava. If playing for the first time and becoming uncertain what would happen if the hoverboard touched the lava, the player might actually not even try to go into the lava, thus for certain would miss finding the lair beneath the lava.

It also turns out that Elon sits in the cave and shouts at his workers to get back to work, even calling them names. There is also a coin here.

From her last comment, ''or whatever'', it seems she doesn't care too much, which make it clear, from the LOTR universe, that neither of these rings in the one ring. It would not have be this easy throwing them into the lava if it had been. There seems to be 16 rings, which is less than the other rings that are ruled by the one ring, the 9 for the humans, the 7 for the dwarfs and the 3 for the elves (19 plus the one ring 20 rings in total). The two girls are playing a dangerous game, the exact opposite of the normal version of the children’s game {{w|Hot lava (game)|Hot lava}}, where they pretend the floor in the house is made out of lava, and that you die if you touch it. However, in this version of the game they pretend to play that the lava is the floor in a house, and they may then just walk out into the lava pool, where they would die.

|Ponytail is trying to break the world record for downhill race on a bike on a volcano. The {{w|Cycling_records#History_of_downhill_records|record}} at the time of this comic was from 2002 and was 107 mph (172 km/h) easily beaten by the 114 mph (183 km/h) that Ponytail reaches as she mocks the previous record holder. There were two different records, one for prototype bike by {{w|Éric Barone}} (the 107 mph) and one for serial production bicycle (102.5 mph (164.95 km/h) set in 2011 by Markus Stöckl). She beat them both and it looks like a very ordinary bike she rides. The all-time record for downhill racing is not using the ashy slopes on volcanos but from racing on snow, and here the record is not in danger from Ponytail as it is a staggering 138 mph (222 km/h) again with a lesser record for serial produced bikes of 130 mph (210 km/h). She will soon hit a rock outcrop so hopefully she has very good brakes...

|''If I don't make it back'' is a common [http://tvtropes.org/pmwiki/pmwiki.php/Main/IfIDoNotReturn trope] in films and books used when the speaker is about to make a noble sacrifice.

There is even a [https://vimeo.com/58319575 song] with the same title by {{w|Tracy Lawrence}}.

Also here are Megan with some kind of device and Cueball on top of a large boulder. Maybe they are investigating the environment on the volcanic slope. Cueball has just discovered the coin hanging above them.

|Explanation needs to be checked by someone who actually knows about the v-scale and bouldering. Does the sentence even make sense in anyway if there is an eruption? Megan and Cueball climbs a very steep part of the mountain slope. Megan refers to the way the difficulty of {{w|bouldering}}, is graded using the {{w|Grade (bouldering)|V scale}}. She exclaims that at the moment the climb is only a V2, but if the volcano erupts this would increase to V7. Since the grade has something to do with how steep and difficult the climb is, the eruption would only make a difference if it immediately shifts the slope they are on to a higher angle. But of course if lava comes down the side, it would also become more difficult, but that is not a usual factor in the V-scale. There are also two other people climbing this part of the slope, and at the top there is a burning three stump showing how active this volcano is. The eruption could seem likely.

|The line "”The time has come” the Walrus said, to talk of many things" is from the poem {{w|The Walrus and the Carpenter}} by {{w|Lewis Carroll}}'s book {{w|Through the Looking-Glass}}, the sequel to {{w|Alice's Adventures in Wonderland}}. {{w|Sauron}} is the main enemy in LOTR, the one who has made the ring, and now needs it to gain his powers back. In this mixed poem the second line is changed but follows the same rhyme scheme. But although ''rings'' would have rhymed with ''things'', it of course have to ''ring'' as the {{w|walrus}} can only put the {{w|One Ring|one ring of power}} on, while uttering the now much more ominous sounding phrase ''The time has come''. Megan is reading this poem/story at the base of the volcano Mount Doom where the ring was created and later destroyed. Like Frodo, Sauron is one of the characters from LOTR who is only mentioned, not shown, in the comic.

Maybe the mother has been reading too many clickbait news on-line? As noted in the other references ''clickbait'' is a recurring theme in xkcd. The mother is near a small lake, so it is likely that there is plenty of insects and other bugs. It is possible to sink into the lake as can be seen in the second image with the hidden parts shown in red.

|Comic : [[1133: Up Goer Five]]
|The book TE was based on the comic ''Up Goer Five'' which was about the rocket that took this space capsule to the moon. When it lands it uses three large parachutes to slow down after the main brake-down during reentry. On top of these sits a bird looking like a hen. It is a hen that can think, but it is still not very clever. It believes that this is three eggs, and is amazed that they are already flying before they hatch, which is of course ridiculous, but they do float in the air... The astronauts inside (two at least, but there should be three if it was one of the moon landing missions) has just been waiting to get close enough to Earth again that they can get a signal on their smart phones. Cueball is even opening the hatch during descend to increase this chance, which would be highly dangerous. Also normally they would land in water (which will though not be the case this time). The reason he does this is that they wish to know how many more likes they (and their mission) has received during the reentry. This would have been relevant if the moon landings had taken place today. There where no social media or internet back in 1969. This is similar to the Cueball who is trapped in the lava lair without connection to Twitter.

|At the bottom of the well in the water (see also the hidden passages image) is a girl. Above to the left of her is a coin. Maybe thrown in by Cueball at the top. Ghost living in wells is a common theme, for instance there is a Japanese movie {{w|Banchō Sarayashiki}} whose [http://www.imdb.com/title/tt0202946/releaseinfo English title] is ''Ghost in the Well''. So this is why this real girl explains that she is actually not a ghost, she just like wells and thus likes to sit in the cold water at the bottom of wells. This could be very dangerous, and she will probably have a hard time getting up. It is also a very deep well, so falling into this well might very well be lethal. There are also many stories (in this case also real stories like the one about {{w|Jessica McClure}}) about kids that fall into wells, some of them surviving being stuck for several days in the wells. Also in movies this story is often used, for instance in {{w|Batman Begins}} the young Bruce Wayne falls down a dry well and is attacked by a swarm of bats, subsequently developing a fear of bats.

That it could run on petrol for cars seems highly unlikely. The question is if she has already filled it up and is heading back with the handle to the gas stander, or if she has just discovered that the hose is not long enough to reach all the way under the wing to the fighter. It will have taken considerable skills to land this close to the station without hitting the cover over the stander. Ponytail is sitting in the shop with a coin. This is the first coin to be discovered when going left from the play-area. There is a long stretch without coins to begin with. The coins on the rock island in the sky it on this stretch, but so far above that most people would miss them altogether. There is also a coin with two birds straight above the right wing on the X-wing. But about three jumps up, so it is easy to miss. the To get into the shop you need to go over the stander and back. Why Cueball have crawled up in the roof is not clear. But maybe he is enjoying the view over the cliff that is to the right of the station. There is a stop sign to the left, but there seems to be no road that way. Maybe that is why you should stop...

First when the coin has been taken, can the string between the birds be seen (see the other image). The birds are three jumps above the X-wing below, and this coin is thus easily missed by the players. In the film the horses are simulated with the sound of two coconuts shells being hit together. Someone asks how they happened to be in England and there is discussion about migratory birds like {{w|swallows}} and the possibility that they have brought the coconuts along with them.

|Cueballs lines is from The Lion King and has been used directly before in the comic Opportunity. Randall has made several references to the film in xkcd, and it is obvious that he was very affected by this film that came out when he was just the right age. Cueball is talking to a child version of Ponytail, whose mother may be the one climbing up the cliff side below. The first three lines of the quote goes as in the film, but then it turns out that the girl is properly referring to the Star Destroyer that would be clearly visible from this cliff as it covers almost the entire right part of this world from just beyond the play-area. (They do not look high enough to see the rock island in the sky, and it would also not cast shadow over an entire region.) As it is not certain players coming here have already been to the right to see the Destroyer it is not necessarily clear that the reply from Cueball should apply to the Destroyer. But if it does then it would be the Emperor Palpatine that he reefers to as God. The emperor is on board the Destroyer near the bridge at the very top rear end of the space ship and has God like powers. It could however also just be a general reference to the {{w|God}} and thus be inferred as if God cast a shadow over an entire region (country). Maybe just in general as if he has a place in the sky that cast a shadow (like sitting on a cloud). Alternatively it could be the people who believe too much in any God, that can be viewed as living under a shadow, as they will not try to see any reality if it does not fit with their religious beliefs.

Recently (2014), there has also been a TV series produced called {{w|If Loving You Is Wrong (TV series)|If Loving You Is Wrong}}. The quote is very romantic, because the speaker is stating that if it is wrong to love a specific person, the speaker chooses to be in love and does not wish to be right. However, Cueball twist the quote quite a lot, saying instead that if it is wrong to love Ponytail then he does not want to love her at all - taking all romance out of the statement. Also in this scene is one of only two instances where Beret Guy appears. Typical of his past appearances, he seems to be occupied by following a small flying insect through the tall grass.

|The tallest man made structure on the ground in this game is the {{w|Washington Monument}} which recently before the release of this comic was refereed to in the mentioned comic. As can be seen in the hidden passages images there are two secret passages, one at the bottom (see this scene for more) and one in the middle of the monument. The one in the central part of the monument is actually quite large, and as can be seen in the images zooming in on the central part there is also a fault line in the monument at the base of this hidden passage. But it doesn't really lead to anywhere interesting. The fault line could be a reference to the {{w|Washington_Monument#2011_earthquake_damage|earthquake damage}} from 2011 where several stones cracked.

|At the base of the Washington Monument Megan and Cueball is looking up at it, and Cueball complains that it doesn't even look like {{w|Washington, D.C.|Washington}}. If he is referring to the city or to the monument is a bit unclear. Of course since this is the only Washington based building in the game it is true that the place doesn't look like the city. If he refers to the monument then it can be questioned if this is because the monument is not an exact replica (in proportions and/or scale). It could also just be Cueball who is not happy about it. In any case it is clearly meant as an indicator that this is supposed to look like the monument, and with the tips apex being made of aluminum (see that scene) as on the real monument, there can be no doubt what is referenced. But it is possible to get to the left side of the monument without going up to see the tip, if the player immediately understands the sign with the white arrow that actually points to a hidden passage through the base of the monument, as can be seen in the second image with the hidden passages shown in red. To the left of the monument there is a flag pole with a blown out flag. It is all black, but it should be the {{w|Flag of the United States|the Stars and Stripes}} as there are fifty flag poles with the US flag (one for each [[1653: United States Map|state]]) surrounding the monument in a circle. On top of the pole there sits a duck looking left. Towards the end of the world to the left on top of the left volcanic rim there also sits a similar duck looking right.

|The tip of the monument is actually {{w|Washington_Monument#Aluminum_apex|made of solid aluminum}} and at the time this {{w|aluminum}} apex was installed it was a rare metal as valuable as {{w|silver}}, but today it is maybe about 1/300 as valuable as silver. So Cueball and White Hat will not become rich based on the metal value. Of course if they did steal the tip of such a famous monument, they might actually be able to sell it to a scrupulous collector at a value comparable to if was just a lump of silver of that weight. White Hat looking over his shoulder spots the Star Destroyer and thus help guide a player that has started going left towards the Destroyer to the right. How they have managed the climb, getting the ropes over the tip, or how Cueball intends to get down with the tip is left to the readers imagination...

|Film: {{w|Avatar (2009 film)|Avatar}}
|This floating rock island may be a reference to the film Avatar where floating rocks is part of the scenery of the fictive moon {{w|Fictional_universe_of_Avatar#Astronomy_and_geology|Pandora}}. The rock in the game is very hard to find by chance, it is kind of unobtainable, which may be a further reference to the film since the reason the rocks do float is a combination of a weak gravity, a strong magnetic field and a mineral whose {{w|Superconductivity|superconductive properties}} allow it to float in magnetic fields. Of course the levitating Hallelujah Mountains in the film contain significant quantities of the mineral which is called {{w|Unobtanium}}. Only thing pointing towards it is the Washington Monument and even if you go up from there, pushing the up arrow continuously for more than half a minute you may almost miss it, as only the far right girl would move through the view. And with two coins around this island it is important to find it in order to get all coins. Apart from the coins and the surprise there is little of interest here, and not even any spoken text. To the right just beneath the rear end of the Destroyer there is a small lump of earth that has floated up from the ground, hovering over the corresponding hole in the ground. Maybe this is caused by the same force that have created this floating island.

It is easy to see how a player of the game, with no knowledge of Randall's way of thinking, may not even think about exploring outside this area, even if they do try to go outside the maze. Because it is possible to jump around in the maze without discovering that you can actually fly rather than just jump. If you only jump once you cannot see the too op the walls.

|This is the starting area where the game begins. There is even some extra text telling you to ''Use arrow keys to move'' but as soon as you do, this text disappears, just like the [[#Messages in Play Area|message you can receive]] below in the view depending on your action in this area. The text below the starting point of the hoverboard Cueball that you control, explains that the game is released on this day to celebrate the release of Randall's new book [[Thing Explainer]] and thus directly references the book. And also explains why this comic has been made, and furthermore why it was released on a Tuesday rather than the usual Wednesday release, which was then skipped this week. It also explains that if you collect coins you can deposit them at the terminal, and when you do it list the score (number of coins and the time used) and rates your achievement. By noting that [http://www.explainxkcd.com/wiki/images/7/7e/17_coins.PNG you got all the coins] if you collect all 17 coins in the play area maze, then it is one more trick to try to make you stay inside the walls of the maze. There is only one small feature that can be spotted from within the maze that breaks the symmetry and may give away the clue of the game. And that is the small stone that lies on the ground to the left. Because why should it be there, if this was just a platform/maze game. The walls cannot be seen if you stay in or just around the outer wall of the maze. But if you go to them you may think this is the end. Another detail about the game to be learned already here is that there can be "solid" black parts of the surroundings which are not solid at all. This can be seen in the image showing the hidden passages in red. Here it can be seen that the ledge beneath the two inverted parenthesis " )( " is not solid, and that you can fall or jump up through this section. This could forewarn you of the hidden passages, especially to the lair beneath the volcano which are the only real hidden place based on hidden passages, but also for those in the Washington Monument and in the cotton trap in the Destroyer and the glitch floor also on the Destroyer.

|The small forest with two large trees and several small ones is the first really interesting to show up if exiting the play area to the right for the first time and finally a person actually speaking shows up (although Cueball at the base of the Washington Monument to the right would be closer). Megan is not saying much, but she is clearly reacting to something. It could be to one or both the space ships above her. Since the Destroyer is already on top of her, as the front end of that ship is just short of being above the right wall of the play area, then it could also be the Rebel Runner she is pointing out. No matter what, following her arm going up and right it is likely that the runner will enter the view, but it is possible to miss it, in which case there would be a long way up to the Destroyer. Megan and Cueball is standing on the edge of a cliff, offering them an excellent view. Stepping down on the plateau below the cliff takes the player close to the lowest possible level to be at in the game. There are no tiles with any white below that level (1073).

This should not be physically possible as the ropes do not seem to be attached to the ground, at least not the one to the left. But there can be no doubt that the drawing shows her standing with both feet on the rope. She is thus not helping Cueball. From here it is not yet know to the player that it is the Rebel Runner they have caught (with anchors) above, but when this becomes clear it will also be clear that they have no chance of holding on to the space ship. But here it seems they are doing a great job. The ground is barren between these wires and a {{w|tumbleweed}} is blowing along to make this even more clear.

|Comic: [[1315: Questions for God]]
|{{w|Fluid dynamics}} is a complex subdiscipline of {{w|fluid mechanics}} that deals with fluid flow. Although it is not their main target they can also be used for {{w|surface waves}} which would be like the {{w|rogue wave}} in this scene. This kind of waves is also known as freak waves, monster waves etc. They are large and spontaneous surface waves that occur far out in open water, and can be extremely dangerous. But as the wave describes to Cueball these big waves can be predicted from the equations in fluid dynamics. Of course Cueball is less afraid of the wave (even though it is {{w|Rogue (vagrant)|rouge}}), than he is fascinated by the fact that it speaks. The wave just replies that the equations are really complicated. That this is the case was for instance part of [[1315: Questions for God]] where a famous quote regarding turbulent motion of fluids is mentioned. {{w|Turbulence}} is also described by fluid dynamics, so they are part of the equations and the {{w|Horace_Lamb#Career| quote}} by {{w|Horace Lamb}} was: "I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is {{w|quantum electrodynamics}}, and the other is the turbulent motion of fluids. And about the former I am rather optimistic." He turned out to be correct as nowadays we have a much clearer understanding of QED, while our understanding of turbulence has improved little. {{w|Richard Feynman}}, who was himself largely responsible for explaining QED, famously {{w|Turbulence|described turbulence}} as "the most important unsolved problem of classical physics". So who knows if these formulas could describe a talking wave? A coin crowns the wave.

|Comic: [[1632: Palindrome]] and the [[:Category:Spiders|Spiders category]]
|Any explanation for the ruin? The palindrome comic was released shortly after this and used a palindrome about the {{w|Panama canal}} which is the first four lines with ''Spider-'' changed with "A" the first three times and then with nothing before Panama as in ''"A Man, A Plan, A Canal: Panama''. The song is inspired by the {{w|Spider-Man (theme song)|Spider-Man theme song}} (see this [https://www.youtube.com/watch?v=SUtziaZlDeE video]), but takes it in a rather different direction. Spiders have been a recurring theme and as the rest of the song tells that the spiders have now breached through the Panama canal using spider-boats and by flooding the gates (in the canal) so now there are spiders in both oceans. If they came from the {{w|Atlantic ocean}} to the {{w|Pacific ocean}} or the other way around is not clear, but there are now spiders on both sides of the {{w|Central America|Central American}} strip of land. If the line ''Spiders float'' refer to actually floating spiders or just because they float on their boat is unclear. But we are forewarned about these spreading spiders with a '''''Look out!''''' (another lyric from the Spider-Man theme song). This threat continues the theme of the [[:Category:Red Spiders|Red Spiders]] especially those from [[126: Red Spiders Cometh]]. There is a coin inside the ruin beneath Cueball who sits on top of the ruin and both sings the song and plays the guitar. Megan just stands inside the ruin at ground level and listens. It is not difficult to get to the coin, but there is only entrance into the little coin room between the ledge under Cueball and the ceiling of the lower room. But it is possible to walk directly in their from the left. Maybe the ruin is in this state of affair because the spiders have crossed the ocean just to the left, the shore of this can be seen at the edge of the scene. But there is no indication of any spiders anywhere else in the comic, in spite of the many animals throughout the comic.

|Megan, in a black wedding dress, and Cueball, with a tie, is married by a female priest in front of a crowd of five sitting in chairs in front of them. In the crowd there is yet another Cueball, Hairy and Ponytail, but the last two it not familiar in xkcd one has a cap on backwards and then a person (M/W?) with black. Just before a {{w|wedding}} it is sometimes customary to ask if any in the crowd has could give a cause why these two people should not be wed. What is not customary is to threaten those who do have any objections that they would then have to plea these in front of the great gangster boss from Star Wars, {{w|Jabba the Hutt}}. In case he has condoned this wedding then you may end up pleading for him to kill you mercifully if you did object anyway. The normal way of saying what the priest does goes more [http://justus.anglican.org/resources/bcp/marriage.pdf like this]: "If any of you can show just cause why they may not lawfully be married, speak now; or else for ever hold your peace." (See the top of page 4 of the pdf file in the link (page 424) and a discussion about this sentences use [http://boards.straightdope.com/sdmb/showthread.php?t=635317 in real life]). Beyond the wedding another Megan is sitting on a large boulder facing the wedding, and behind her a third Cueball is having a picnic with a second Ponytail. The question here is if Megan looks at the wedding or turns her back to the picnic. Depending if the player went right along the ground to begins with and saw the wedding first or went through the Destroyer and came back the other way and saw the picnic first the players preconceptions on this questions may be completely different. In either case it still looks like Megan would have liked to be with Cueball (either the one in the tie or the one at the picnic. Of course with characters drawn "randomly" in many places she may bot even belong to either scene. Standing on the rock with Megan hoverboard Cueball cannot see either of the scenes, but standing between Megan and either scene, she can be seen together with either of the relevant Cueball and another girl. In the first case with the wedding, she might have wished she had the courage to speak up in spite of the Jabba threat. In the other case she may feel rejected by the happy picnic couple and has turned her back to them. Poor Megan. Ponytail and Cueball seems to enjoy their picnic lunch in the open air though.

|Someone with better Latin knowledge than using Google translate would be most welcome to chip in here It is so common to have your motto translated in to the dead language {{w|Latin}} that there even is an entire category for {{w|Category:Latin mottos|Latin mottos}} on Wikipedia. Since no one really speaks the language anymore, and only few learn it well enough to just read any sentence, by doing so you actually hide this motto that you probably would like to tell people about. Of course if it is famous then many will now the meaning just from the Latin words like for instance {{w|Carpe diem}} (seize the day). However, most of the time, like the one Megan is explaining to her friend, it would make much more sense to just write it in your native language (English in this case), but then of course there would be no need for a motto, where you ask yourself why you suddenly again changed into Latin. So it is a very Meta joke. There is also a cemetery in Click and Drag. The Latin in the motto is not correct, but close, and it could both be Randall that just tried his best, or on purpose as there are probably many "private" mottoes out there that has not been checked by a professor in Latin. The original sentence ''Cur ego committitur dictar latinae'' cannot be translated by for instance {{w|Google Translate}} as the word ''dictar'' does not mean anything in Latin. But if it had meant speaking it would be close as the Google translation comes up with ''Why did I start '''dictar''' Latin''. Also the word ''just'' is completely missing, but could have been included by using ''iustus''. However, this part could have been added when Megan translated her already ''silly'' motto. ''Dictar'' is, however, not that far from some words that do make sense in the context. For instance ''dicta'' without the "R" means ''statements'' and ''dicti'' means ''said''. ''To speak'' is ''dicere'' (still relatively close to dictar), but ''speaking'' generally translates to ''loquitur'' but also dicere can be used here. Going the other way by just putting the English sentence into the translator ''Why did I just start speaking Latin'' gives this: ''Cur ego solum Latine loquantur'' (but only if the question mark is not used???) This, however, then translates back to ''Why did I only speak Latin'' so it makes no sense. The best Latin sentence seems to be ''Cur ego iustus committitur loquitur Latinae?'' which Google translates directly to the correct ''Why did I just start speaking Latin?'' sentence. However, by using dicere (which should be interchangeable with loquitur) as in ''Cur ego iustus committitur dicere Latinae'' this translates (again only without the questions mark???) to ''Why did I just start to speak Latin''. As the meaning is the same as the previous sentence and since dicere is at least close to dictar, and since ''just'' is not really needed then the sentence: ''Cur ego committitur dicere Latinae?'' comes close enough to real Latin and the quote and the meaning as Google translates this into ''Why did I start to speak Latin?'' '''Cur''' - Why '''Ego''' - I am (or am I) '''Committitur''' - start '''Dictar''' - uncertain (possibly '''Dictare''' - to dictate) '''Latinae''' - Latin A possible translation is "Why did I just start speaking Latin?".

|In ''How to count things'' in TE there is also a drawing of a huge foot, used to count mass, not length... The two Cueballs check out an inscription at the foot ([[559: No Pun Intended|pun intended]]) of a monument. Typically old relics from the past has been demolished, and if only part of a human body is displayed (at least when it is not just a {{w|Bust (sculpture)|bust}} supposed to only have head and shoulders), then it is often assumed that the rest of the statue has been lost. Just like the missing arms of the ancient Greek statue {{w|Venus de Milo}}. These arms was there originally. But as it turns out as Cueball reads the transcription someone in the past just wished to show the future his huge foot. Suggesting that this is either actual size, or just that he was very proud of at least one of his feet. He also mock anyone reading the inscription by calling them the derogating word [http://www.urbandictionary.com/define.php?term=dirtbag dirtbags]. This is a recent word so if this was an ancient monument it would be highly unlikely that it said that. Of course it could be Cueballs translation of what is actually written, or as this is not necessarily old, it is not just part of the original monument but the entire unbroken statue of a foot, then it could be a contemporary artist who made it. However it is just in front of the pyramid to the right, and in front of the real pyramid {{w|Pyramid of Khafre}} the {{w|Great Sphinx of Giza}}, also much larger than life size lies. (It has lost it's nose by the way). So this could be the games version of such a large statue in front of a pyramid. As from the scene to the left of this giant foot, the inscription that Cueball reads is probably in Latin, in which case it could have read something along the lines of: ''Io, de futuro sacculo terra! Reprehendo sicco meus ingens radices!'' (which could be translated back to ''Io, for the future of the bag, earth Check out my huge foot!'', since there was no words for ''Yo dirtbags'' in Latin.

|Ponytail greets the player as (if) he approaches the pyramid from the left. She points up the side of the pyramid and gives a protip (a feature often used in xkcd). The tip is yet another indication that the Destroyer is above (the tip) of the pyramid. She tells the player to keep "climbing" after the top (that is not usually possible, but the hoverboard can keep on flying). By doing so the player may reach up to the entrance leading into the spiral corridor (although it will be difficult to keep the same incline as the pyramid on the way up). Ponytails last remark about showing tips on startup makes her sound like she is some kind of program, that can give you interesting hints and tips every time you start the program. If you do not wish this, you can just leave the [http://help.formulatrix.com/rock-maker/3.4/Content/Resources/Images/RM%203.0.3/StartUp%20Tips.png check box unchecked].

|Another completely flat grassy landscape but with a strangely elongated Cueball drifting in the wind. Characters flying is depicted in two scenes where Ponytail flies, but she does this of her own will. Here is seems like Cueball is just drifting with the wind towards the end of the world, which is only two scenes away, and he is the last character along the ground towards the end. This is in some way reminiscent of Click and Drag, where the Cueball floating with the balloon to begin with, can also be seen at the very right end of the world. But then again here it more seems like Cueball doesn't have a choice, and he also seems to be out of shape.

|An overview of the entire Rebel Blockade Runner ''{{w|Tantive IV}}'' from the opening scene of the original Star Wars movie. It has four rooms (one blown open), a small canon room that cannot be entered by the hoverboard and two corridors. The rear is the large engines. There are three coins. There is a clear symmetry along the center, as the two canons and the two parabolic antennas are placed symmetrical on the top and bottom hull, and also the curves of the hull is symmetric. In the second image link the way to find the runner from the ground via the wires can be seen (six coins). And in the third the way to find the Destroyer above via the torpedoes can be seen (14 coins). The Destroyer is thus not hidden, like for instance the Floating Rock Island or the Hidden Lair beneath the lava lake, and there are many less direct indications that there is a runner from all the people who comment on them or even directly or indirectly point the way to the Destroyer. The Runner is supposed to be 150 m long.

|Film: The {{w|Star Trek}} universe
|The bridge of the Rebel Blockade Runner is crammed with interesting scenes. First on the bridge itself a long haired woman (the captain) is mocking both Star Wars and Star Trek fans alike by using the [https://www.youtube.com/watch?v=vcRX0Gw1aaw opening line] from the Star Trek series about stating the {{w|stardate}} for the captains log on board the first space ship ever shown in the Star Wars franchise. Hairbun behind her (it could be {{w|Princess Leia}} who also has buns but above each ear) is clearly distressed by this ”mistake”. This could either be because she is a Star Wars fan that dislike Star Trek or because the stardate used is the real date, November 24, 2015, on which the comic was released (as well as the book ''Thing Explainer'') instead of using the normal convention for stardates with a four or five digit number plus a decimal like 1513.1. Given that the long haired woman has the appearance of [[Danish]], this may be intentionally rather than a mistake. There is another reference to Star Trek universe in the scene where the torpedoes are fired from in the Destroyer above, so no less than two Trek infiltrations in the opening scene of Star Wars Beneath the bridge there is a smaller room where Ponytail and Megan spoofs [https://www.youtube.com/watch?v=X69NCLxwLEY Luke's Lightsaber Training] from the original Star Wars movie where {{w|Luke Skywalker}} practices under {{w|Ben Kenobi}}'s guidance while {{w|Han Solo}} comes with snide remarks. Ponytail (in Luke's place) holds a {{w|lightsaber}} above which floats a sphere which represents the small remote controlled {{w|Jedi}} training device from that scene. Megan both guides like Ben and comments like Han. She holds some kind of cannon that she obviously loads with T-shirts from the box behind her. As she tells Ponytail, a true Jedi trains with a [https://www.youtube.com/watch?v=FgCz7C6jEIk t-shirt cannon]. Han Solo's quote begins like it but ends quite differently: [https://www.youtube.com/watch?v=tOuCbDkKIs4 Good against remotes is one thing good against the living it's something else]. He would also prefer a {{w|Blaster (Star Wars)|blaster}} as he explains: [https://www.youtube.com/watch?v=V268Qk6-xsw Hokey religions and ancient weapons are no match for a good blaster at your side kid]. There is a coin behind Ponytail Above the bridge there is a hatch open where hoverboard Cueball may enter and a Cueball is standing behind the hatch looking down along the hull. There are canons both above and below the hull, the one on top has a coin in front of the barrel. There is a similar canon with a coin in front on top of the Destroyer. Beneath this canon is a tiny room where another Cueball is pouring several small bullets from a bucket into a black box labeled bullets (for the canon). From this room there is a small shaft down to the main corridor in the Runner. But this shaft is too slim for hoverboard Cueball to pass up through it, or rather for the board to get in. Cueball can pass into the hole but the board holds him back from reaching up in the small room. The canon below has two of the anchors from the wires going to the ground attached around its barrel. The third anchor is stuck in the bottom hull further down the hull. It is unclear how this last has become attached to the hull! In the corridor that runs away from the bridge a small robot on wheels drive towards left. Similar types of robots are often seen in the Star Wars universe and there is also [http://www.explainxkcd.com/wiki/images/5/5f/1608_1034x1091y_Torpedo_canon_below_Destroyer.png another robot] looking like two of these on top of each other in the Destroyer above where the torpedoes connecting them ends up. Further down the corridor Ponytail is walking to the right while singing indicated with two notes. Above the canon at the bottom of the hull on a ledge with an entry to the ship is a third Cueball holding a fishing rod out over the ledge so the hook hangs in the air. Maybe he is fishing for either of the two birds that are flying around the line. What appears to be a loaf of bread or [http://www.explainxkcd.com/wiki/images/5/58/1608_1014x1078y_Three_wires_and_reaching_up_to_anchors_in_Runner.png a cracker is attached to the hook] at the end of the line.

|Further explanation needed by someone with more computer skill than Second Cueball and me who wrote the current version... Also is there some reference to someone saying something like that to an attack, rather than the one with C3PO The reference to the Death Star plans are from [https://youtu.be/yHfLyMAHrQE?t=340 the opening scene] in the first Star Wars movie. The sentence uttered by First Cueball is said by a Storm Trooper to Darth Vader. The [http://m.imdb.com/title/tt0076759/quotes?qt=qt0440708 rest of the quote] is not quite like in the comic. Rather is goes like this:
:Darth Vader: [addressing the Tantive IV's captain, whom he is interrogating] Where are those transmissions you intercepted? WHAT have you DONE with those plans?
:Captain Antilles: We intercepted no transmissions... This is a consular ship... We're on a diplomatic mission...
:Darth Vader: [shouting] If this is a consular ship, WHERE is the ambassador?
:Darth Vader: Commander, tear this ship apart until you find those plans! And bring me all passengers, I want them ALIVE!
The comic jokes with the way Darth Vader seems to assume that if the plans had been found on the computer, then no one else would have had access to them. The second Cueball, although not Vader, represents a superior that have absolutely no idea about how computers work, in spite of his insistence that he actually do. If the data has once been intercepted they could have been shared or copied to several other computers or devices or even been printed. By finding them in the main computer they would only make sure that they were indeed intercepted, but not be certain that they have not been delivered to the rebel base.

The other two Cueballs on top of the ship stand over a hole in the hull going into a small room above and left of the large room. It seems that the fourth Cueball has made this hole directly from the outside (i.e. it is not caused by an exploding torpedo from the Destroyer above). Because he confirms when the third Cueball asks if he just came down to make the hole without permission. The third Cueball thinks this is rude. This is, of course, hilarious as if a space pirate or any other attacker of a space ship would ask permission before attacking. And also the idea that he might get permission for asking is likewise crazy. To call this rude is also a weird way to look at such an attack. {{w|C3PO}} uses [https://www.youtube.com/watch?v=FWoG9tKf1lA this as reply] to a comment made to him by a similar droid in the second movie.

|In this overview of the top rear of the hull of the Runner, there are four scenes with two persons in each, with no less than six Cueballs. Beginning with the scene to the far left the two first Cueballs discuss what type of Star Destroyer is shooting at their ship from above them. They are clearly tilting their head far back to look up. The first Cueball comments on how huge it is and asks if it is an {{w|Star_Destroyer#Imperial_class|''Imperial'' class}} Destroyer. "''Imperial'' class" is the designation of the Destroyer ''[http://starwars.wikia.com/wiki/Devastator Devastator]'' that followed the Rebel Runner ''Tantive IV'' in the opening scene. There is also an more than 10 times as large version called a {{w|Star_Destroyer#Super_Star_Destroyer|Super Star Destroyer}}, which were featured in the two sequels in the original trilogy. But even the original Star Destroyers were improved during the movies, so when the improved Destroyers came out they became known as ([http://starwars.wikia.com/wiki/Imperial_II-class_Star_Destroyer Mark II], Mk-II or plainly II, and the original (as Devastator) became known as [http://starwars.wikia.com/wiki/Imperial_I-class_Star_Destroyer Mk-1]. The second Cueball agrees with the first and suggest that it is an Mk-1 and thus makes it even more clear that this scene is actually the opening scene of the original Star Wars movie. But then again, he continues, it depends weather this is the {{w|Star Wars expanded universe|expanded universe}} (now know as ''Star Wars Legends'') where all authorized media (books etc.) released based on the Star Wars franchise should be counted in, or if it is only the movies sanctioned directly by George Lucas (and now Disney). What he says is that in all those work there could be so many other types os ships mentioned, that he could mistake for an Mk-1, that in that universe he would not be certain at all. But in the "official" universe he would claim that it was an Mk-1 ''Imperial'' class Star Destroyer. In the next scene Ponytail and a third Cueball fights a ridicules fight with bows and arrows against the Destroyers 100+ torpedoes raining down from above. Ten of these can be seen falling, one hits the ship and one has just exploded in a big ''boom'', to be compared with the feeble ''twang'' made by Cueballs bow when he fires the arrow. When later discovering how far there is up to the bottom of the Destroyer it only becomes even more silly. In the third scene two more Cueballs (four and five) look up at the torpedoes falling down in an arch over their heads. The fourth Cueball asks why they still keep firing. And the fifth Cueball tries to explain. A {{w|Gun turret|turret}} is generally a weapon mount that houses the crew and a projectile-firing weapon and lets the weapon be aimed and fired in a given cone of fire. So it is this crew, that are the turret operators. There is also such [http://www.explainxkcd.com/wiki/images/b/bc/1608_1012x1078y_Bridge_on_the_Rebel_Blockade_Runner.png an operator] on the Rebel Runner below the top canon (or turret), in the scene with the bridge. The reason they keep fighting is given that they just do their own thing and that is annoying. This indicates that these two Cueballs do no longer think that the Destroyer needs to fire anymore on the Runner, and thus also indicates that they are part of the crew from the Destroyer send down to take over the Runner. Thus it is annoying that the shooting has not stopped as it puts them in danger. If they belong to the Runner then they would not think it weird that the shooting continued. It turns out to be Megan who is the [http://www.explainxkcd.com/wiki/images/5/5f/1608_1034x1091y_Torpedo_canon_below_Destroyer.png turret operator in the Destroyer]! At least they can be happy that it is regular torpedoes. (See the explanation of the scene regarding the Torpedo canon below Destroyer). In the final scene at the very end of the hull is the sixth Cueball together with Megan. She holds on to him as he tries to toasts a giant marshmallow on a stick by holding it in front of the exhaust pipe of the Runner. This would must likely melt the marshmallow instantaneously... In ''Red world space car'' in TE the Mars rower also toasts a marshmallow on a stick over a small fire.

There is a coin behind the lowest of the engines. There appear to be {{w|truck nuts}} attached to the rear of the ship beneath the hull. These are plastic or metal accessories, typically for cars, which resemble a pair of dangling testicles/balls. They are attached under the rear bumper of the vehicle so they are visible from behind as a practical joke. Some find it is in so bad a taste that it should be banned or fined.

|The 12 last torpedoes leads up to the canon below the Destroyer that has fired them all towards the runner far below. In the control room (or turret room see explanation of scene where the torpedoes hits the Runner) is Megan and Cueball. She explains that she used regular torpedoes rather than the much more powerful {{w|Weapons_in_Star_Trek#Projectile_weapons|'''photon''' torpedoes}}. This may cheat some to think this is a reference to the weapon Luke Skywalker used when destroying the Death Star in the original Star Wars movie. But they were called {{w|List_of_Star_Wars_weapons#Ship-mounted|'''proton''' torpedoes}}. Photon torpedoes are a standard ship-based weapon armed with an {{w|antimatter}} warhead and one of those alone would probably take a ship like the Runner out if it was not shielded... However, they are used by the {{w|Starship Enterprise}} in the Star Trek universe. So this is the second (but more subtle) mixing of the two competing franchises connected with the torpedoes in the opening scene of Star Wars. The first being on the bridge of the Runner below. Above the control room there is a shaft up to a corridor in which a small robot of the types typically seen on spaceships in Star Wars is seen.

|The top part of the front of the Star Destroyer also has an entrance as does the bottom section (see above). There is a coin above the hull. This first corridor leads to a playpen pit filled with playpen balls, which is a recurring subject in xkcd. Cueball and Megan is adult sized (i.e. as big as hoverboard Cueball) and it is thus a clear reference to Grownups. There could be water down below the balls as a fish is seen jumping out over the surface. But given that there are no splashes from the balls Cueball throws in the air, it could also just be a gimmick by Randall. To have something like this in a Star Destroyer kind of ruins the mood surrounding these war machines. Something seen several times throughout the space ship.

|Comic: [[1620: Christmas Settings]]
|Although the original {{w|piñata}} was star shaped it is now common to use different shapes like the horse or donkey displayed in the comic. Children usually hits the piñata with a club until it breaks and falls down revealing candy or toys inside. The two Cueballs, Megan and Hairy are adults though as big as hoverboard Cueball, just like in the playpen pit. It is though not uncommon for adults to participate in hitting down a piñata. But to do it with a {{w|lightsaber}} would defeat the purpose of this game as it will go right through the piñata on contact thus spilling the contest out on the floor in the first go. The Cueball with the lightsaber can thus confidently say that he got this. But it seems like the other Cueball is trying to stop him and that Hairy, holding the club they were intended to use, puts a hand protectively on Megan. A lightsaber would be a very dangerous weapon, and should not be used lightly in a playful setting. As a side note any candy/toy in the path of the ligtsaber as it passes through the piñata will melt/burn immediately. Lightsaber noises are mentioned in the title text of the Christmas Settings comic coming out shortly after this one.

This is the first example of such a corridor, near the bottom hull of the Destroyer, showing that it is not a featureless outer hull. Apart from the ever increasing width of the Destroyer there are some steps up and down, to indicate some of the features seen in the Star Wars movie.

|Another enjoyable activity to attend to by adults is located here in the front sections of the Destroyer: A swimming pool. Don't worry about Ponytail jumping head first into the water, as can be seen in the hidden passage image it is rather deep. Cueball and Megan is already in. Supposedly there is a rung ladder up again on the side, but it cannot be seen in this slice through the Destroyer. A coin hangs in the top corner of the room. When standing with the hoverboard on the bottom of the pool it will be possible to see that there is a coin on the outside of the hull in the indentation in the hull below the pool. From the outside, however, it will not be possible to see that there is a pool above as the water is the same black (to the eye) as the solid hull.

So "You shall ''not'' '''not''' pass" = You '''shall''' pass, and when you do you get a coin. It is easy to miss that there are two times not in the sentence which is for certain intentionally by Randall, as the spoken sentence thus do not match the appearance of Cueball with a hand out. If hoverboard Cueball jump ship at the ledge to the left he can fly over to the next ledge where Cueball and a guy with black hair is preparing to jump of the ship using parachutes. Behind them there is a shaft going up into the ship with a coin.

The shaft going down goes to the two guys with parachutes. There is a coin next to the shaft.

|To the left in this overview is the roundabout like structure that Cueball above it calls a rotary, which has given name to this section of the ship that follows after it up to the section with the cave. The Destroyer becomes much broader here especially due to the two large steps that the top part of the hull takes in the middle and to the right in this image. In the hidden passage image the cotton trap is revealed with the two entrances to the room below and to the corridor to the right that leads past different traps into the cave. At the top and bottom middle of the image there are two cars, and as it can be seen in the hidden passage image the hoverboard cannot rest on top of those. In the composite ''Swallow Runner'' image the Rebel Runner has been placed in the opening in the bottom hull to reveal that this is indeed the opening in the bottom of the Destroyer that swallows the entire Rebel Runner in the opening scene of the first Star Wars movie. This feature is thus a direct reference to the "real" Devastator Destroyer and thus a direct reference to the opening scene and to Star Wars. Below the individual scenes in the Rotary section will be described.

|This is the {{w|Traffic circle|Rotary}} that has given it's name to the section of the Star Destroyer from the structure itself and right of this until the section where the cave is located. A rotary is also known as a ''traffic circle'' and is a large version of a roundabout with several roads exiting from it. At the top of the upper left passage (see the scene above) Cueball is looking down into this structure and calls it a rotary (hence the name). Typically for a real life rotary it is possible for pedestrians to enter the central part of the structure as is the case here with the small room with the hairy kid and his potted plant and coin. Large rotaries may have more than four roads leading away, but in this case there are four, and neither of them are leading straight away up/down or left/right. Three of them are almost at a 45 degree angel, but the one going down is only a little of to the right, and soon turns straight down. Only other feature is the Cueball rushing right on his bike in the corridor leading away from the rightmost exit. There are several bikes throughout the comic, with two more in the Globe of Death above the bridge of the Destroyer and one going down the right slope of the Volcano. Entering the rotary for the first time there are of course three new directions to move along in, making it a special point in the users exploration of the Destroyer.

|Self-reference to title of this comic, and the conversation guide comic released shortly after this is also referencing this entire comic as it complains that hoverboards are not real yet. There is both another hoverboard Cueball and a hoverboard Megan in this room, but compared to the players hoverboard Cueball these two are some what more advanced, and managed to swoop around the coin in the middle. The room can only be entered from the right. To the left there is only a dead end with three completely empty rooms, so don't bother going there if you are in a hurry to pick up all the coins...

|In this dead end room Cueball is lying on the hood of a car. Hoverboard Cueball cannot copy this as the car is not a solid segment of the image. The hull is not far away, and the car room is right where one of the large steps in the upper hull appears. Right outside there are two coins at the bottom and top of the step. These cannot be seen from inside the room. There is no fast way to get outside from here, and actually no easy way to get a car into this room either. In ''Sky Toucher'' in TE there is also a car stuck in the middle of the sky scraper a long way from the parking cellar. In this comic there is actually even one more car in the Destroyer, but that is at least close to an exit ledge (see scene below).

|Megan is referring to the fact that space ships in Star Wars often fly fast also inside the atmosphere of a planet. Not something you would normally design for. Though in the case with the Destroyer and Runner they did not go inside the atmosphere as depicted here in the comic, in the scene from the original Star Wars movie. The blonde woman comes with a comment typical for b-moves, who cares if this would work in real life, it is just a film. There is a large gap in the bottom hull ending here and starting in the ''Shaft corridor with coin and room with coin over ledge at bottom of hull''. This large section is the section in which [http://www.explainxkcd.com/wiki/images/e/e1/1608_Entire_Rebel_Blockade_Runner_swallowed_by_Destroyer.png the Destroyer swallows the Rebel Runner] in the opening scene of the first Star Wars movie, as mentioned in the overview above. Behind the two women, who are standing on a thin ledge where the large gap ends, there is another car (see scene above). At least it is clear how this car could get into this room (and out again). Above the car there is a coin. Behind the car there is a corridor going into the Destroyer, but quite high up on the wall for a normal exit. The car cannot be used as a step to jump in there, as it is not part of the solid picture.

|The corridor from the room with Megan and the car is long. In the middle of it there is a shaft going up (a long way). Just inside this shaft Ponytail is seen flying up, hands in front of her like another Superman. Above her in the shaft there is a coin. This is not the only place in the comic where Ponytail is flying. Although here it seems like an automatic thing (like Superman), whereas down below on the ground below the Destroyer she has to flap her arms violently, but then actually manages to take of from the ground. In a space ship like this Destroyer there could both be a system to let people float upwards, some gravitational effects or just plain effects of the flying itself, wheres down on the ground flying like that would be magic for sure. But at least there seems to be some correlation since it is Ponytail that flies in both cases.

|After the shaft where Ponytail flies up (see more in the scene above) the corridor continues to a pit which Cueball and a kid have been covering with leaves and sticks. It seems like they are making a trap, which is even more likely seeing that the bottom of the pit has six sharp spikes that would likely impale any unlucky victims that fell in. Alternatively (given the words Cueball uses), they have made this hole by mistake, and now tries to cover it so no one sees it. If he meant it to be a trap he might instead have phrased it, "so they won't see it until it is too late". The kid looks like the kid in the room at the rotary, as they have the same hairdo.

|Overview
|
|
|
|
|
|With the comment from Hairbun about peristalsis - the bowel movement getting food etc. through the digestive system, and with the three chambers with coins above a colon like structure, leading into the corridor with these motions, with a coin both going down the colon and through the peristalsis, there can be no doubt that this is the digestive system for this ”living” space ship, and coins is what it lives off. This interpretation can further be extended to the very front end, where there is the appearance of a head that eats coins (see the front end overview) and at the rear end a coin is bouncing out at the very last shaft before the very end of the ship. Suggesting where this animal gets rid of the waste products afterwards. (The rest of the ship is not part of this interpretation).

|Following the corridor from the room with Cueball on the hoof of a car leads to a part of that corridor experiencing {{w|peristalsis}}. This is the kind of muscle movements that causes food to move through the {{w|human gastrointestinal tract}}. Hairbun is telling Cueball that this is indeed corridor peristalsis, so a way for the corridor to move stuff along. As there are coins at both end of this section it is quite clear that these coins are moved along by the corridor itself. The indentations of the corridor is so strong that the corridor is not wide enough to allow hoverboard Cueball to pass through. So to get both coins another route needs to be found. The shortest way is to go up the shaft behind Hairbun, passing the two empty rooms with coins on the way to the top of the Destroyers hull. To get to the other side hoverboard Cueball will then have to pass through the Destroyers colon like structure to the right. See below. As mentioned in the overview above this is a clear reference to the human digestive system, or in this case the Destroyers ditto.

The reason for showing this scene is to show the closeness of these two digestive system structures. In ''Box that cleans food holders'' in TE Ponytail yells Wheee! as she slides through a pipe inside the machine on her stomach, a mix of the action performed by Cueball and Ponytail in the colon like structure. Ponytail is sliding towards a coin at the bottom in one of the colon loops. The top part of the colon can be seen in the next scene.

|This is the upper entrance to the colon like structure into which Cueball is looking. (See scenes above). To the left is the top hull of the Destroyer which takes two huge steps up at this place. Cueball is standing in a corridor with three small rooms, each with a coin in the top of the room. This seems to be a place to hold the coins until they are ready to move down the colon like structure, where another coin is already moving through, going down to the corridor peristalsis in the corridor below, where more coins are moving through the ships digestive system. Going over the hull and down this colon like structure is the fastest/shortest way between the two separated sides of the corridor peristalsis.

|Two Cueballs work as a mining company in this corridor which they are expanding. It could be that they are digging for gold, but if that gold should be represented by coins, it is weird that the coin hangs above the Cueball with the {{w|pickaxe}} in the higher section of this corridor, instead of being in front of him. The other Cueball drives away with a wheelbarrow full of the rubble they have dug free from the ship. This is another indication of how big the ship is. It is easier to just dig a new corridor than to build the corridor into the ship to begin with. Further to the left in the Destroyer there was another dead end corridor that looked like it had been dug out - see the scene ''Dead end shaft with rubbles at bottom of hull.'' But here the mining company had left (even though there also was a coin there). The shaft to the left goes up to the hull right of the canon from the scene above.

|Here are two different zoom out of the cotton trap room with the spark gap room below. In the first overview a zoom out is shown with only these two rooms. There are four coins inside and two on the outside of the hull. The three coins around the cotton trap is almost connected by the cotton, as can be seen in the next overview where the hidden passage through the cotton is clearly marked in red. As can be seen there is a very deep black hole beneath the surface of the cotton (which Ponytail states is cotton). From the bottom of the cotton trap going left will lead to a hidden entrance to the top of the spark gap room. Going right will lead to the hidden entrance to the corridor with traps going to the left entrance to the cave. There are coins on each exit as well as just above the cotton to the right. The third image is a further zoom out to show the entire surroundings of the cotton trap room. (And the last is with the cotton etc. turned red). Here the traps in the corridor leading to the cave can be seen as well as the opening into the cave. Below that the strange spiral corridor can be seen. Both these scenes will be described below in the cave section. To the left the shaft and corridors that connect the two rooms even if not noticing the hidden passage can be seen. It is the corridor with the trap covered by Cueball and the shaft where Ponytail flies up. Three more coins are visible in this wider zoom out for a total of nine coins in this area. The two rooms will be described in further detail below. All of the rooms that can be entered through the cotton trap can also be entered through different entrances from other routes. This means that failing to find out how the cotton trap works, will not prevent the player in reaching either the spark gap from below or the cave to the right.

|Entering this room along the top corridor reveals Ponytail standing at the beginning of a steep descend. She clearly warns the player about a trap made of cotton. As can be seen in the hidden passage image most of the black at the bottom of the descend is not solid floor but a hidden passage. Given Ponytails comment it must be assumed to be made of cotton. Given that hoverboard Cueball is not affected by the cotton and can move either up again, or out left or right it is not a trap for him. But other unlucky persons falling into the cotton might not be as lucky. If this is not a trap in it self, there are several traps if moving out to the right (where the coin is below the cotton level). This corridor goes to the cave, but first after passing five traps. See more about the entire surroundings in the overview scenes above.

|The bottom of the cotton trap is a dark place. But as can be seen in the red hidden passage image it is possible to move both left and right to get out. In either case a coin can be obtained at the exit. The left exit leads to a shaft going into the spark gap room below, and the right exit leads through a corridor with traps into the cave. Going up in the spark gap room below will clearly reveal the shaft up. But if the cotton trap has not been discovered at this time, it is likely that the player will not attempt to breech the wall, and would thus fail to enter the cotton trap from below. The coin could easily seem enough reason for this dead end shaft above the room.

|Why is ''JS'' written on both electrodes This room is called the {{w|spark gap}} room, because there seems to be a spark between the two large electrode like structures marked JS. Cueball is watching this, maybe he is the evil inventor that has created this device. At least another Cueball is climbing high above him up on the wall to the left, and when the player passes him on his hoverboard he asks the player no to tell about him (''shh''). It is unclear if he is sneaking away, spying or sneaking down to attack the other Cueball. A coin is hidden behind the spark gap, but as the spark gap is of the "red" type of black hoverboard Cueball can pass without problems into the coin. As can be seen in the other image displaying the lower part of this scene, the coin outside of the hull is close by, and actually the two coins above each other down there are in the same small image (see the first of the small images).

|This is the corridor exiting the cotton trap room (with a coin as mentioned previously), see the cotton in the hidden passage in red image. The corridor leads to the cave, but to get there five traps has to be passed. First there are four hammers with jagged edges that opens and closes with much force as perceived by the noises. And then a pit with a fire has to be surpassed. Of course as can be seen in the "red" image, neither of these traps are any problem for hoverboard Cueball as they are all of the red type of black. But it is a clear indication that the player is about to enter some interesting place, which is true as the cave is one of the most interesting places in the Destroyer. Although there are two other ways to get into the cave, it is by far the most interesting way to enter the cave for the first time!

|Below the corridor to the cave is a strange corridor which spirals into nothing in the middle. There are no coins in this section so this is a zoom out without any further zoom in on this section. The room at the top seems like a starting point to go into the spiral. The corridor to the right goes into the huge glitch floor room below the cave. The shaft down goes out the bottom of the hull.

They only need a little parallel shift to make them into one big circular room.

|Comic: [[1610: Fire Ants]] and [[1641: Hot Dogs]]
|The ant comic was released only a week after this comic and refers how cool ants are. Ants are also used twice in TE A zoom in on an ant is used to indicate size in ''Earth's past'' and under the ''Tree'' in that explanation there is an ant colony where one ant is much bigger than the others; an ant queen, a clear reference to the ant queen in the Destroyer. The other comic is a discussion running along exactly the same template ending in ''Eww''. This is probably a reference to a part of Orson Scott Card's "Xenocide" in his Ender series. In it, the main character, Ender, visits a hive queen "bugger" he saved on his travels and became friends with, at a time after the queen has settled in on a new planet. At one point, Ender brings other humans to meet the queen at a time when she was giving birth to some of her drones. This is most likely meant to represent a parody of that conversation or else represent a comedic idea of his first conversation with her when she had been birthing, where Ender is alone and is speaking to the Hive Queen. In this version, when he finds out that she is in the process of birthing more ants, rather than being compassionate and understanding with the Queen (as he is in the book), Ender is weirded out like the other humans he brings along with him later.

|Comic: [[1213: Combination Vision Test]]
|{{w|synesthesia}} is a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. One typical version is where numbers are perceived as having colors. This was used in the comic referenced. In this comic a wish for something makes Megan almost taste it. If she did indeed have this dysfunction, she might already have what she wished for... This is one of the rare incidences where there are two almost identically Megans in one scene.

==Coins==
*There are 169 coins.
**Here should be more details about the coins and where they are located and how many.
*For more details see here for [[1608: Hoverboard/Images coins|coins location]].
*The Coins are not part of the drawing.
**They are added later for the game, and they are superimposed on top of the image.
**This means they are always on top of the black parts of the image.
**There are no coins located over any part of the type of black that you cannot pass through.
**But in more than one occasion the coins cover some of the black parts that you can walk through.
***See example here [http://www.explainxkcd.com/wiki/images/0/0b/1608_with_coin_1070_1095.png with coin] vs. [http://xkcd.com/1608/1070:-1095+s.png without coin].
***The coin is here a lamp, and then when it is removed it reveals an exploded lamp beneath the coin, and also one more insect.
****This means that the coins can never be hidden by anything black, and although coins can be hidden away in a secret lair, they can never be hidden under water or lava or holes in the Washington Monument.
****Because if there were any coins in these dark areas, the coins would still be shown on top of the image.

==Technical aspects==
The game was made by [http://chromakode.com Max Goodman] who has previously worked on [[1416: Pixels]]. The source code for the game can be found [https://xkcd.com/1608/tigl.js here].

===Image tiles and coordinates===
As previously noted, the comic bears considerable resemblance to [[1110: Click and Drag]]. The comic is made in much the same way, with 'drawn' images "glued" together to form a large "map", with the illusion of infinite bounds made possible through space saving techniques where blank tiles are not stored and are instead painted white. The boundary between blank squares and 'drawn' squares is made clear as any white space in the normal images has a very slight grey tint. Thus, seams between images and blank spaces can be discerned.

The tiles for the map are stored as simple PNG files in the naming scheme: X:-Y+s.png. An example from the starting tile can be seen here: http://xkcd.com/1608/1000:-1074+s.png, with the coordinate (X, Y) coordinate (1000, 1074).

Each file is 513x513 pixels in size, one pixel is reserved as overlap to ensure seamless joining of images. The image tiles names are listed as coordinates in an X - Y grid with X in the range from 928 to 1108 and Y in the range from 928 to 1112.

Internally in the game, the position of the player is given for instance as (X: 512187, -Y: -549668) for the starting position. Then these numbers are divided by 512 and rounded down. This gives the coordinate of the tile that the hoverboard is currently in.
:(X: 512187, -Y: -549668)/512 => (X, Y) = (1000.37, -[-1073,6]) => (1000, 1074) when the numbers are rounded down.
The bottom left corner of the first tile, would thus be (1000, 1073), and the top left corner (1000, 1074) => (512000, -549888).

The collision map is encoded in the darkness of the black. Using an image manipulation program, one can easily find the secret pathways even in the zoomed out maps provided below by enhancing the contrast of the dark areas.

====Play Area used as example====
*Using the Play Area as an example some of the features mentioned in this section will be explained.
**The images used below can be seen together [[1608: Hoverboard/Screen-shots#All of Play Area|here]].
*The hoverboard begins in in (X, Y) = [http://xkcd.com/1608/1000:-1074+s.png (1000, 1074)].
**But even while staying within the Play Area, defined as the area where you will not be told to [http://www.explainxkcd.com/wiki/images/a/ae/Return_to_the_play_area.PNG Return to the Play Area], you can see all or part of 20 images.
***You can move one image left and right of the starting point before reaching the walls, and one image up without getting too high. But from there you can see part of the images one step further left, right and up, and from the starting level you can see part of the black images below as well.
***This makes it a 5 times 4 images rectangle.
*This first example shows a full size image combined from these 20 images that make up the play area starting in the top left corner with image [http://xkcd.com/1608/998:-1076+s.png (998, 1076)] and finishing down the right corner with image [http://xkcd.com/1608/1002:-1073+s.png (1002, 1073)].
**Here is only the images themselves, nothing with the game parts, i.e. coins and hoverboard Cueball:
***[http://www.explainxkcd.com/wiki/images/e/eb/1680_Play_Area_Full_Size_Images_Only.png Play Area Full Size Images Only].
*This next example shows both where the tiles are and what you see to begin with, i.e. the starting view when loading the comic to begin with. Still without any in game details.
**Here the tiles are lines out with green and the view frame is in red. From this it can be seen that the view is somewhat larger than a single image.
**More precisely the view is 1.43 times longer and 1.34 higher than a tile giving an area almost twice as big (1.93 times), but only going about 1/3 of a tile length in each direction:
***[http://www.explainxkcd.com/wiki/images/7/7b/1680_Play_Area_Full_Size_Tiles_and_View.png Play Area Full Size Tiles and View].
*This third example shows the game version, with coins and hoverboard, but still the hole Play Area and hence also the read viewing square.
**This is included to indicate which coins can be seen to begin with and also how the view is centered around Cueball and the hoverboard.
**Cueballs center is also the center of the view. His center is defines as the line of his body in the X direction and just above his hands in the Y direction.
**The view is 12 times as high and 30 times as wide as the Cueball on hoverboard (and compared to a tile these numbers are 9.4 and 20.8 times).
***[http://www.explainxkcd.com/wiki/images/8/8b/1680_Play_Area_Full_Size_Coins_Hoverboard_and_View.png Play Area Full Size Coins Hoverboard and View].
*The last and fourth example is the same as above, but again with the green tiles.
**This to indicate the size of a tile compared to Cueball
**It also shows that although there are 12 coins in the starting view, the one at the top left is clearly in the image above, and the three other at the top are grazing the top edge of the image:

===Functionality===
By observing page code while playing, the game grabs and displays images based on location, and subsequently clears all non-visible images. The game uses what seems to be a position syntax to retrieve the intended images live, and returns an error if such an image does not exist, such as a blank area. This technically means things could be added to the world and updated live. If the player is moving sufficiently fast or if the internet connection is slow, this means that the player can get stuck in a black area that does not load in time.

This also means that the game does not have coded top or bottom limits, so any attempt to find the ''ceiling'' of the game will be futile unless the game is tweaked. The game does however have side limits, and it is not possible to go down further than image with Y coordinate 1073 (and it goes down to 1069 in the full image), so there is a bottom limit in the game. If using a [[#Cheats and Exploits|cheat mode]] this may be different.

Opening the console will display the text: what? hoverboard not enough for you!? in the log. Activating goggles mode will cause the text 'B-)' to appear in the log.

===Bugs and errors===
*On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile.
*Sometimes the timing of the game is completely off. This can make the Cueball move extremely slowly. Or on the other extreme make him go faster so the images jumps and makes the graphic look horrible.
**This error was actually used to discover something about how you move when pressing the arrows - see under [[#Controls|Controls]].
*If the focus switches from the game to the page, the Cueball can freeze in midair. The same thing can happen if the window border overlaps the play area.

===Controls===
The keyboard controls are as follows:

*'''Go Left''' - Left arrow key, a or h
*'''Go Right''' - Right arrow key, d or l
*'''Go Up (jump or hover)''' - Up arrow key, w, or k
*'''Go Down (if gravity disabled)''' - Down arrow key, s, or j

This control scheme covers the three commonly used directional key sets: WASD a set of keys commonly used by modern games; HJKL a set of movement keys used by vi and applications which attempt to mimic vi key controls (vim); and the arrow keys, the most generic set of keys which is usually accepted by most applications which take movement as input, these were commonly used in older games.

On devices which have a touch screen and tilt sensor (portable devices like mobile phones and tablets) the controls are as follows:
*'''Go Left''' - Roll the device anticlockwise
*'''Go Right''' - Roll the device clockwise
*'''Go Up (jump or hover)''' - Tap the screen

After inspecting the source code, there appears to be no way to move down on a portable device, this is only relevant if gravity is disabled (see [[#Cheats and Exploits|Cheats and Exploits]]).

*If you keep down the left/right control you will keep moving along in that direction as long as no object blocks you.
*A jump will only take you a certain height.
**Then you drop down.
**The jump is fast to begin with, then gravity stops you and revert the direction.
**When descending again you accelerate to begin with but quickly reach a terminal velocity.
*If you jump repeatedly while keeping a left/right control down you will jump in that direction.
**But if you only jump one time, while keeping down the direction control, then you will stop moving forward after about 2.8s, from then on you will just keep falling straight down, or stop where you reached if on the ground.
**This makes quite a difference when you jump into an opening from a high structure. If the background is completely white, you cannot see that you do not continue to move forward, and will thus not be aware that you are now falling straight down, instead of going left/right.
**It can actually be quite difficult to notice as you will leave any structures that can indicate this issue very quickly.
***Of course if you notice that you land much too close to some high structure from where you base jumped, you will begin to understand. For instance falling off the floating rock, and not moving away from under neath it during that long fall.
***The timing was discovered because of one of the [[#Bugs and errors|bugs]] in the program that sometimes makes Cueball move extremely slow, so one jump takes more than 3s.
**The solution if you wish to keep moving to either side while descending, is that after the jump, you release and repress the left/right control. Then you will continue moving in that direction as long as you do not jump again.
**As long as you continue to jump you will also keep moving laterally if you keep one of those buttons down. The is quite counter intuitive.
***This also means that when you jump up over a long distance (or continue to jump hover over the landscape), you will not have this issue, since every jump reactivates the lateral movement.
***But if you jump over a small obstacle and then just keep another arrow down, you will soon stop, which could fool you into believing that it was an obstacle on the ground that held you back.

===Cheats and Exploits===
Aside from the obvious ability to move out of bounds in the game, there are some more obscure hidden features which can't be enabled through normal gameplay, the ones found so far are as follows:

'''Modes''' are activated by opening the Javascript Console (F12 [Or Command-Alt-I in most browsers under Mac OS X] to open Developer Tools, then Console tab) and writing corresponding commands. 
'''Click to expand:'''

<div class="mw-collapsible mw-collapsed leftAlign" style="width:100%">

*'''Gandalf Mode:''' ''i.am.gandalf = true'' - jumps and runs further. displays a white gandalf hat that works well in places where the avatar can't be seen.
*'''Speedhack:''' ''explorer.opts.speed= *Value*'' - Speed hacking, with 1 = normal speed
*'''Jump Hack:''' '' explorer.opts.jumpForce= -*Value*'' - Jump hacking, with -1 = normal jump (positive values cause the hoverboard guy to move down when jumping)
*'''Mewtwo mode:''' ''mewtwo = true'' - disables gravity
*'''Noclip mode:''' ''noclip = true'' - player is able to move around the map without collision. Combine with Gandalf and Mewtwo modes for free easy map traversal.
*'''Goggles mode:''' ''ze.goggles()'' - displays a small window showing area around the player in a pixelated manner. The goggles indicate collision boundaries (where the player touches the world) in cyan lines. Black pixels that are passable (such as other characters or text) will be highlighted red (allowing secret passages to be discovered).
*'''Position Tracking:''' ''explorer.pos'' - Returns the player location to the console. Can be used to track position and test to ensure you are still moving. Must be re-entered to compare positioning.
*'''Position Setting:''' ''explorer.pos.x = *Value* or explorer.pos.y = *Value*'' - Can be used to manually set a position within the world. The start is at x: 512106, y: -549612. The left terrain bound is at x: 475210, y: -553711. The right terrain bound is at x: 567281, y: -549712. Mewtwo and Noclip modes are a must for exploring in this way.
* '''All the above:''' ''explorer.opts'' - Contains all the game's parameters. You can directly mess with ''gravity'', collision (''disableCollision''), jump force (''jumpForce'') and speed (''maxSpeed''), among others. Run ''Object.keys(explorer.opts)'' to list all available parameters you can tweak.
* '''List all coins:''' ''explorer.objects'' - Array containing the position of the 169 coins of the game.
* '''Disable tilt input:''' ''getEventListeners(window)['deviceorientation'][0].remove()'' - on Macs with motion sensor, disables tilt input which causes problems controlling the avatar

'''Getting All Coins: ''' To instantly get all coins, input the below into the console window. Does not use standard formatting of [i] to avoid conflicts with i.am.gandalf

for (var T = 0; T < explorer.objects.length; T++) {
explorer.objects[T].got = true;
}

To teleport to the next coin every time you press the left or right arrow:

var T = 0;
document.onkeydown = function(event){
if (event.keyCode == 37) { T = T-1 }
else if (event.keyCode == 39) { T = T+1 }
else { return }
T = T % explorer.objects.length;
var coin = explorer.objects[T];
explorer.pos.x = coin.x1; explorer.pos.y = coin.y1;

For a quick tour of all the coins:

var delayInMilliseconds = 1000; // 1 second delay between each teleport. feel free to change this.
var index = 0;
explorer.objects.forEach(function(x){
setTimeout(function(){
explorer.pos.x = x.x1;
explorer.pos.y = x.y1;
x.got = true;
explorer.frame(); // forces a redraw
},
(index + 1) * delayInMilliseconds);
index++;
});

To see a list of coin coordinates you have not yet collected:

var L = 0;
for (var S = 0; S < explorer.objects.length; S++) {
var I = explorer.objects[S];

1379: 4.5 Degrees

2016-08-28T23:19:20Z

SISenor:

{{comic
| number = 1379
| date = June 9, 2014
| title = 4.5 Degrees
| image = 4_5_degrees.png
| titletext = The good news is that according to the latest IPCC report, if we enact aggressive emissions limits now, we could hold the warming to 2°C. That's only HALF an ice age unit, which is probably no big deal.
}}

==Explanation==
This comic represents the impacts due to climate change by demonstrating the changes in climate that should be expected with a given change in global temperature. This is done by detailing the world's climate in geologic periods where the global average temperature has changed by one or more "Ice Age Units," or IAU. The comic defines an IAU as the difference in global temperature between today and the last ice age, about 4.5 °C. An IAU of 0 represents modern global temperature.

One IAU unit happens to be the expected increase in global temperature the world will see by the end of year 2100. The prediction of 4-5 degrees Celsius of warming may not appear significant, but is easy to see as a substantial difference when comparing today to the last ice age.

: An IAU of -4 is associated with {{w|Snowball Earth}}. Snowball earth is a near-total freezing of the entire surface around 650 million years ago, in the {{w|Cryogenian}}. This may have been the greatest ice age known to have occurred on Earth.

: An IAU of -1 is associated with the last ice age. During this time Randall's neighborhood was buried under an ice sheet.

: An IAU of +1 is the predicted global temperature by the end of year 2100. While it makes sense to assume it's just as drastic a difference as -1 IAU, we still don't know the actual nature of what it would be, which is why it is represented by a question mark in the comic.

: An IAU of +2 is associated with the {{w|Cretaceous Thermal Maximum|"Hothouse Earth"}} of the early {{w|Cretaceous period}}. At this time there were "{{w|Arecaceae|palm trees}} at the poles" as there were {{w|Polar forests of the Cretaceous|polar forests}} during Cretaceous summers. (Average temperature of North Pole during the summer is 0 °C or 32 °F. 0+2*4.5 = 9 °C = 48.2 °F, hot enough for trees to grow at the North Pole under hypothetical 2 IAU scenarios)

An increase of 4.5 °C (+1 IAU) seems like a small change in temperature, but the changes it would cause are likely very large as it can also be described as halfway to palm trees at the poles.

The topic of ice coverage over various cities has previously been covered in [[1225: Ice Sheets]].

This comic and [[1321: Cold]] present a different perspective on Global Warming than Randall presented earlier in [[164: Playing Devil's Advocate to Win]]; it is not clear whether Randall has changed his perspective or if the Devil's Advocate comic was meant to be satirical to the point of not representing Randall's true views on the issue.

The title text expands, demonstrating that the potential impacts of an increase by the IPCC report's best case scenario of 2 °C, about half an ice age unit, makes controlling climate change seem more urgent. The figure of 2 °C is the most commonly agreed {{w|Climate change mitigation#Temperature targets|temperature target}} that assumes the creation of aggressive emissions limits at the time of the publishing of the comic.

===A1F1 Scenario===
The 4.5 degree increase is predicted by the bern2.5cc simulation (a moderate simulation) of the A1FI scenario. In the A1FI scenario the world has a high dependence on fossil fuels, experiences "very rapid economic growth", a declining world population by 2050, as well as a high rate of increase in energy efficiency after 2050.

===Trivia===
The oldest known animal fossils ({{w|Sponges#Fossil record|sponges}}) are from the Snowball Earth, while {{w|Flowering plant#Evolution|flowering plants}} became the dominant plant species during the Cretaceous period. It is believed that the entire Earth was frozen for the first time about 2,400 to 2,100 million years ago, which could have been a result of the {{w|Great Oxygenation Event}}.

The 200m {{w|Current sea level rise|sea level rise}} given in the last panel for a "Cretaceous Hothouse" (i.e. if all ice on earth melted, including the Antarctic ice cap) could not be explained by this melt-off alone. If all the ice melted the water level would only increase by about 60-80m, according to {{w|Antarctica}}, [http://www.grida.no/publications/other/ipcc_tar/?src=/climate/ipcc_tar/ IPCC Third Assessment Report] (section 11.2.3 on Greenland and Antarctic Ice Sheets) and [http://water.usgs.gov/edu/sealevel.html Sea Level and Climate: USGS Water-Science School]. Additional sea level rise can be expected from thermal expansion of seawater, and indeed the main reason for rising sea level at the moment is actually caused by this expansion of the sea due to increasing temperature. But the high-end 500-year projection for a 4x increase in CO2, at {{w|Current sea level rise#IPCC Third Assessment|expansion of the sea}}, is for an additional 2m due to thermal expansion, with a decreasing rate of growth over time. (Some of the sea level change in the Cretaceous are due to changes in bathymetry.)

The 5th and most recent {{w|Intergovernmental Panel on Climate Change}} (IPCC AR5) presents four alternative trajectories for future concentrations of greenhouse gasses, termed {{w|Representative Concentration Pathways}} (RCPs): RCP2.6, RCP4.5, RCP6, and RCP8.5. They are named after possible ranges of radiative forcing values in the year 2100 relative to pre-industrial values (+2.6, +4.5, +6.0, and +8.5 W/m2, respectively). The hottest of these, RCP8.5, is predicted to result in a warming of 2.6 °C to 4.8 °C for the 2081−2100 period, and between 3 and 5.5 by the year 2100 ([http://www.climate2013.org/images/report/WG1AR5_SPM_FINAL.pdf Working Group I Summary for Policymakers]).

The lack of internationally binding agreements makes breaching an increase of 2 °C more and more likely.

969: Delta-P

2016-05-08T22:20:41Z

SISenor:

{{comic
| number = 969
| date = October 26, 2011
| title = Delta-P
| image = delta p.png
| titletext = If you fire a Portal gun through the door of the wardrobe, space and time knot together, which leads to a frustrated Aslan trying to impart Christian morality to the Space sphere.
}}

==Explanation==
{{w|The Lion, the Witch and the Wardrobe}} is a book in which four children accidentally wander into a world known as {{w|Narnia}} through a wardrobe that only allows passage through to Narnia when you aren't looking for it. In the comic, someone connects an anchor to the wardrobe and throws it into the ocean. The formula describes the flow of water through the open doors, which means that a steady stream of water at an approximate velocity of 200 meters per second will flow into Narnia.

The evil {{w|White Witch}}, who has made it [http://www.goodreads.com/quotes/93155-always-winter-but-never-christmas "always winter, and never Christmas,"] could not have anticipated that the wardrobe portal would suddenly begin spewing approximately 400,000 liters of water per second into Narnia.

Sea water freezes at low temperatures and flowing water freezes at even lower temperatures, depending how fast it is going. Water jetting out from this portal would be flowing very quickly indeed, approximately 200 meters per second as the comic says, this is about 450 miles per hour, or 720 kilometers per hour. And the water flow is approximately 400,000 liters per second, again, provided in the image above. The force of this water jet would be incredible. Much more, in fact, than the force of a tractor trailer careening down a highway.

This water would not freeze. First it would decimate any forest trees or iron lamp post in front of it until it eventually slowed down and fell to the ground. There it would create a rapidly expanding river of sea water. Narnia would not stay frozen for long. Snow would melt, ice would break apart and the valley would quickly flood.

Delta-P is a mathematical expression for the difference in pressure. Here the difference is between the depths of the ocean and the open air of a forest that creates the flow of water.

The title text references the video game "{{w|Portal (video game)|Portal}}" in which you fire a portal gun into walls etc. to make "portals" that can open holes in other places so that you may portal through. In the game you cannot shoot a portal through a portal, but [[Randall]] is saying that if you try to create a portal with the portal gun through the wardrobe, space and time knot together. {{w|Aslan}}, the lion in the title, was [http://www.rapidnet.com/~jbeard/bdm/exposes/lewis/cs-lewis.htm written by Lewis to be an actual representation] (scroll to the section "Is Narnia an allegory?") of {{w|Jesus Christ}}. The {{w|Characters in the Portal series#Personality Cores|Space Core}} is a Personality Core from {{w|Portal 2}} that doesn't care about anything but [http://www.youtube.com/watch?v=BVn1oQL9sWg wanting to go to space].

This is a classic [[xkcd]] based on the intersection of literature, math and video games.

571: Can't Sleep

2016-05-08T22:16:10Z

SISenor:

{{comic
| number = 571
| date = April 20, 2009
| title = Can't Sleep
| image = cant sleep.png
| titletext = If androids someday DO dream of electric sheep, don't forget to declare sheepCount as a long int.
}}

==Explanation==
[[Cueball]] is in bed and is having trouble sleeping. He tries the old standby of {{w|counting sheep}} as they jump over a fence, but upon reaching 32,767 sheep, 65535 sheep jump back over the fence and start counting up again from -32,768. This is because when a whole number or integer is represented in a digital form, such as on a computer, the number's range is limited by the amount of space used to store it. When the greatest possible number given the storage space is exceeded, an arithmetic overflow occurs, which results in starting over at the least possible number given the storage space. This is not at all unlike a car's odometer. Imagine an odometer with six digits reaching 999999. Upon driving one more mile or km, the digits will roll back over to 000000.

In this case, the least and greatest possible numbers are -32,768 and 32,767, which implies that the storage space used would be two bytes. In addition, it's clear that the number is designated as a signed number, meaning that it can be either positive or negative.

However, even if Cueball had this limitation, it would never actually pose a problem. By 32,767 sheep, at a rate of one sheep per second, Cueball has been counting for over nine hours. This would signify that he has extreme insomnia and probably needs treatment, and also that he has spent the entire night counting, and therefore would just get up and start the day rather than count sheep all over again from -32,768. Moreover, according to an experiment conducted by researchers at Oxford University, ''counting sheep is actually an inferior means of inducing sleep'' (see the {{w|Counting sheep|Wikipedia article}}).

The title text refers to the 1968 Philip K. Dick science fiction novel ''Do Androids Dream of Electric Sheep?'', which was adapted into the perhaps more widely known Ridley Scott directed 1982 film ''Blade Runner''. The implication is that if we ever do create androids that dream of electric sheep, we should make sure to give them sufficient storage space to store numbers large enough such that an arithmetic overflow will be far less likely to occur, even if they count for a long time. A "long int" consists of four bytes rather than two, so instead of being limited to a range from -32,768 to 32,767 the number will be capable of storing numbers from -2,147,483,648 to 2,147,483,647. "sheepCount" is a possible name for a variable to be used in a computer program. Declaring a variable tells the computer that it should allocate a portion of memory to be associated with the variable name given. For those who might be unfamiliar with common programming practices, "sheepCount" is named using what is commonly referred to as {{w|CamelCase}}, meaning that all words in the name ("sheep" and "count") are pushed together and the first letter of every word after the first is capitalized. This is one of several common approaches to naming variables in computer programming.

715: Numbers

2016-05-08T21:54:29Z

SISenor:

{{comic
| number = 715
| date = March 17, 2010
| title = Numbers
| image = numbers.png
| titletext = The typical internet user (who wants to share) has an IQ of 147 and a 9-inch penis. Better than the reverse, I guess}}

==Explanation==
The graphics use the popular search engine Google to show how many hits (or web pages) are returned as relevant based on a given search replacing <X> by different numbers.

;Bottles of beer
:The top one is of the popular children's song {{w|99 Bottles of Beer on the Wall}}. In this song, the singers begin with 99 bottles and with each repeat of the verse, decrease the bottles of beer by one. The graph shows a slowdown at 66 bottles of beer, something highlighted. A spike occurs at 49 bottles of beer, which seems to be a popular variant (possibly due to 49 bottles taking about half the time that 99 would).

;Boy/girlfriends
:On the second row, the left graph represents how many girl or boy friends someone has had. They seem pretty similar, though the logarithmic chart may be working on that. There is a clear peak at four girlfriends.

;School grade
:In the middle of second row is a curve for how old (in grade) Internet users seem to be. Going purely by grade, the average is at 7th grade. However, using the notation of Freshman (9)/Sophomore (10)/Junior (11)/Senior (12), there's a notable resurgence.

;Penis length
:The graph on the far right of the second row describes Internet users talking about the lengths of penises that they "have". (This would include both males discussing their own penises and persons of both genders saying that they "have" their boyfriend's penis, or, less plausibly, a severed penis.) Several websites report 5-6 inches (~13-15 cm) is considered average, but it doesn't appear that way on the Internet. There is a general trend (also shown by the line), but the maximum, 9 inches (23 cm), peaks way above the trend line - indicating that guys think they can pull this one of, although 12 inches (30 cm) peaks way above the trend line as well. Probably because 12 inches equals a foot.

;Cup size
:The third row contains four graphs. The far left is the breast size of the Internet user. (This presumably refers to female users, since male breasts are not typically measured in cup size.) The actual breast size is generally considered a bell curve around a B or C cup, yet the hits on Google describe almost an exact opposite trend. Taken with the above male penis length and this describes a trend where either the "average" person posting information seems to embellish or the majority stay quiet. Typically those with small breast will complain, and those with large breast will complain or brag. Those that are content with a C cup do not need to do either.

;I have never had a boyfriend
:The second graph on row three is number of hits per (mostly) female Internet users talking about how old they are without having a boyfriend. There's a spike at 18. The comic was written in 2010; as of 2014 the spike does not exist. Google behaves very strangely in this case, as it shows two very different numbers for each search.

;Glasses of water a day
:Third from the left in row three is the number of glasses drunk per day. Many "health authorities" claim that 8 glasses of water a day should be the most healthy. This {{w|Drinking_water#Requirements|common misconception}} is not supported by scientific research.

;Number of lights
:On the far right is a description of the number of lights. The spike at four is due to a famous scene from {{w|Star Trek: The Next Generation}}, episode {{w|Chain_of_Command_(Star_Trek:_The_Next_Generation)#Part_II|Chain of Command Part II}} where {{w|Captain Picard}} answers that there are four lights, despite pressure to answer that there are five. This is itself a reference to {{w|George Orwell|George Orwell's}} novel {{w|Nineteen Eighty-Four}}, where {{w|Winston Smith}} is tortured until he "learns" to be unsure of the number of fingers being held up by his torturer, despite him only holding up four.

;Number of problems
:Bottom left is a reference to the popular {{w|Jay-Z}} rap song {{w|99 Problems}}. It is the only reason that ''100 problems'' only ends up second by more than a factor of 100.

;IQ
:Bottom right describes the {{w|IQ}} of the Internet goer compared to the average. By the definition of the test the average is 100 with a standard deviation of 15. However, the comic implies that the average claimed IQ closes in on 133 more than 2 standard deviations above the real average! This high average are thanks mainly to the million who has given their IQ as 147. There are four other peaks that are also labeled, and these peaks are the only other above 100,000 hits, but neither of these have much more than 200,000 hits. Apart from these five there are only 5 more with more than 50,000 hits. Note the log scale of the y.axis!
:Many studies have shown that people today would score a higher average than 100 if they took the earlier test - an effect know as the {{w|Flynn effect}}. However, new test from today should still average out to 100, as an IQ of 100 is defined as the average of any give IQ test.
:The five labels: Why 147 is so popular is hard to guess? The {{w|maximum break}} in {{w|snooker}} is 147, but it is unlikely that this is known by enough to make a difference here. There is also a frequently repeated factoid that Albert Einstein scored an IQ of 147 but there's no real record or consensus of this. That 100 (the average) peaks out is obvious. 110 - ten more also makes sense. In general there are almost always more hits at every 5 and 10, than the two values before or after. 133 is a third of the way to 200, and also it will take you clear of the {{w|Mensa International|Mensa}} requirement for membership of 132 on the {{w|Stanford–Binet Intelligence Scales}}. Why 142 is popular is also difficult to say. Of course {{w|Answer_to_Life,_the_Universe,_and_Everything#The_number_42|42 is a special number}} for fans of {{w|The Hitchhiker's Guide to the Galaxy}}, so 142 for an IQ score could be helped to peak for this reason. Although then it is no longer 42... (But an IQ of 42 would be really bad!)
:The scale of the graphs x-axis is completely off. This can easily be seen from the labeled points. Whereas 100 and 110 is close to the mark, the point labeled 133 is much closer to 140 than 130 (at about 138) and the 147 point lies clearly past 150 (at around 152). It is, however, for sure the scale that is off as there are the correct number of points between all five labeled points.
:There is a clear point on the y-axis at 80, but then there seems to be a gap up to the next point, and there are also only 16 points between this first point and the point labeled 100. It thus seems that while there are in fact about 20,000 who claim as low an IQ as 80, then there are not enough who claims a score of 81-83 for them to be shown in this graph. The graph begins at around 80-90 hits because of the log scale so there could be some hits, but way less than the lowest point on the graph which lies close to 1000 hits. From an IQ of 84 and up to 168 there are a point for each IQ for a total of 86 points (with the point at 80).

;Title text
:The title text refers to the searches. It concludes that the average (male) internet user has a 9-inch penis and an IQ of 147. Humorously it continues to state that this is better than the reverse - having a 147-inch penis (over 12 feet or 3.7 m) and an IQ of 9 (only 2 % of the population have below 69).

482: Height

2016-05-08T21:26:11Z

SISenor:

{{comic
| number = 482
| date = September 29, 2008
| title = Height
| before = [[#Explanation|↓ Skip to explanation ↓]]
| image = height.png
| titletext = Interestingly, on a true vertical log plot, I think the Eiffel Tower's sides would really be straight lines.
}}
{{TOC}}

==Explanation==
''Height'' uses a {{w|logarithmic scale}} to depict the contents of the {{w|universe}} at progressively smaller distances from Earth (less high above the Earth), starting at the highest possible "point", the edge of the {{w|observable universe}}, going all the way down to the grass beneath our feet. The comic is a direct companion piece to [[485: Depth]], also released on a Monday the week after this one. ''Depth'' similarly uses the logarithmic scale to depict the Earth at progressively greater magnification (going "deeper" down), from Earth's surface (the grass) to the interior of a single proton.

At the very top the top (edge) of the observable universe is described as being 46 billion {{w|light years}} above the Earth. The universe is "only" about {{w|Age of the universe|13.8 billion years old}}, so the {{w|cosmic background radiation}} that reaches the Earth today, has also only traveled 13.8 billion light years. However, during that time {{w|Metric expansion of space|the universe has expanded}}, so the galaxies that formed from that spot where this background radiation was emitted 13.8 billion years ago, would now be 46 billion light years away. This has lead to many {{w|Observable_universe#Misconceptions_on_its_size|misconceptions regarding the size}} the most typical being that the radius of the observable universe is "only" 13.8 billion light years. See this video, ''[https://www.youtube.com/watch?v=QXfhGxZFcVE How Do You Measure the Size of the Universe?]'' for a great explanation of the 46 billion light years.

To the right of the text, [[Black Hat]] stands atop the comic, having just dropped a cat off the edge head first; he is clearly going to test if the cat will land on it's feet, being a jerk per his usual character. It will take some time though, before the cat reaches Earth...

As one scrolls down, the depicted distances become less compressed, until arriving at the surface of Earth, all the while approaching a 1:1 scale with real-life distances. As shown in [[1162: Log Scale]], if [[Randall]] didn't do this, the comic would be much, MUCH longer.

In this comic, most objects that are grounded on Earth are scaled logarithmically on the vertical axes and linearly on the horizontal axes (some are scaled linearly on both axes). Displaying objects in this manner noticeably distorts their shape; the Great Pyramid, for instance, looks not like a pyramid but like a bullet.

Outside of the Earth's atmosphere, the objects are placed at their actual distances from Earth on the log scale, but their shapes are not subjected to the logarithmic scaling of Earth objects, instead appearing as they would be seen (otherwise, round objects like the sun would appear more egg shaped, with the flatter side facing upward). However, objects are still much larger or much smaller than they would be in real life, in order to allow them to be properly seen.

In the title text, Randall muses on how the inwardly-curved sides of the {{w|Eiffel Tower}} might actually become perfectly straightened when subjected to this logarithmic distortion, although it is shown to bulge in the comic proper, meaning Randall probably doesn't fully believe his own musings. The actual shape of the Tower approximates an {{w|Exponential function|exponential curve}}, which would indeed give a straight line on a log scale, although it was actually designed by {{w|Gustave Eiffel}} to minimize wind resistance rather than to be mathematically exact (the design is so perfect that the amount the Tower sways in the wind is less than the amount it is distorted due to thermal expansion of the sunlit side).

===Objects===
All objects are sorted from bottom to top by their maximum distance from earth for objects in a solar orbit, and their current distance for others.

Enceladus was known in 2008 to have a possible subsurface ocean and active geysers, and a paper co-authored by well-known planetary scientist Caroline Porco in Astrobiology during that year (when the comic was published) spelt out the case for searching for life there (McKay et al. 2008 "The Possible Origin and Persistence of Life on Enceladus and Detection of Biomarkers in the Plume", Astrobiology 8(5):909-919). In 2015, the {{w|Cassini probe}} sampled material thought to be from Enceladus' geysers, and scientists have found evidence that it's subsurface ocean closely resembles a particular kind of deep sea hydrothermal environment on Earth known to harbor life.

A more distant possibility is that Randall is referencing Saturn's largest (and much more well known moons) {{w|Titan (moon)|Titan}}, the only known moon to have an atmosphere and lakes. It was long predicted that there may be bodies of liquid on the surface filled with liquid methane and ethane (Titan is too cold for liquid water and life as we know it, but ethane and methane remain a liquid at those temperatures). There is some speculation that exotic forms of life based on extremely cold exotic chemistries may form in such conditions, with liquid hydrocarbons playing the role of the solvent (the role water plays in terrestrial life).

1179: ISO 8601

2016-05-08T20:45:08Z

SISenor:

{{comic
| number = 1179
| date = February 27, 2013
| title = ISO 8601
| image = iso_8601.png
| titletext = ISO 8601 was published on 06/05/88 and most recently amended on 12/01/04.
}}

==Explanation==
When abbreviating the date into numerical form, {{w|Date format by country|various areas of the world}} tend to list the year, month, and day in different orders (as well as with different delimiting symbols), which can cause confusion particularly when the day value is 12 or lower allowing it to be easily interpreted as the month and vice versa. As a {{w|public service announcement}}, this comic states that there is in fact one international standard for writing numeric dates, set by the {{w|International Organization for Standardization}} in its {{w|ISO 8601}} standard.

The comic then proceeds to list several discouraged ways of writing out the date of the comic's publication, as they do not match the standard. It begins with several commonly used ones in countries around the world, but then begins to list increasingly uncommon ways, ranging from strange (Roman numerals) to quirky (binary, Unix time) to essentially impossible (painting the numbers onto a black cat).

The title text provides a perfect example of the kind of ambiguity that can arise when non-standard formats are used. The ISO standard was in fact published on 1988-06-05 and amended on 2004-12-01. This is mentioned in the title text in mm/dd/yy format; however, there is no way to naturally figure this out, particularly with the second date. With the year truncated to two digits and all three numbers at 12 or lower, the date referring to December 1, 2004 may well be interpreted as 12 January 2004, or as 2012-01-04.

Date formats was again the subject in [[1340: Unique Date]].

The other mentioned formats are:

{| class=wikitable
! Date !! Explanation
|-
| 02/27/2013
| MM/DD/YYYY, used mostly in the United States.
|-
| 02/27/13
| MM/DD/YY, same as above but with the year shortened to two digits.
|-
| 27/02/2013
| DD/MM/YYYY, used variously in South America, Canada ({{w|Date_and_time_notation_in_Canada|officially uses ISO 8601}}), Australia, New Zealand and Europe.
|-
| 27/02/13
| DD/MM/YY, same as above but with the year shortened to two digits.
|-
| 20130227
| YYYYMMDD, same as ISO 8601 without delimiting punctuation. Allowed by the standard. Technically not ambiguous but is hard to read as a date at first glance.
|-
| 2013.02.27
| YYYY.MM.DD, used in Japan. Same as ISO 8601 except with different punctuation.
|-
| 27.02.13
| DD.MM.YY, used in Germany, Russia, etc.
|-
| 27-02-13
| DD-MM-YY, used in Denmark, Netherlands, Indonesia, India, Bangladesh, etc.
|-
| 27.2.13
| D.M.YY. It is common in several areas to abbreviate the month or day to a single digit and drop the leading zero when possible.
|-
| 2013. II. 27.
| YYYY. MM. DD., with month as {{w|Roman numerals}}, used in Hungary.
|-
| 27⁄2-13
| D⁄M-YY, traditional format in Sweden
|-
| 2013.158904109
| Year and decimal fraction of year. 0.158904109 is a decimal approximation of 58/365, with February 27 being the 58th day of the year. Allowed in ISO 8601 as it is not ambiguous; presumably easier to read for computers/programs but difficult for humans.
|-
| MMXIII-II-XXVII
| The ISO 8601 standard but written in Roman numerals. Never used as a traditional standard anywhere as it is hard to read, parse, and interpret for no benefit.
|-
| MMXIII LVII⁄CCCLXV
| Year followed by its partial fraction 57/365, all in Roman numerals. Equally useless as the above. As a note, apparently this 'standard' is different from the decimal fraction two rows above, as the decimal fraction notation uses the ''end'' of the day (first day of the year is 1/365 while the last is 365/365), while this uses the ''beginning'' (first day is 0/365 and last is 364/365).
|-
| 1330300800
| {{w|Unix time|UNIX Timestamp}}, a standard method of storing absolute time in many computer systems and defined as the number of seconds since 00:00:00 on 1970-01-01 (UTC). The Unix time listed here appears to mistakenly be for '''2012'''-02-27, which is also mentioned by [[Randall]] in the original transcript.
|-
| ((3+3)×(111+1)-1)×3/3-1/33
| A useless format where the numbers 2013, 2, and 27 written as needlessly long arithmetic expressions using just the digits 1 and 3. For additional confusion, the values are delimited by slashes, enabling confusion with the fraction bar. (If evaluated literally, the entire expression evaluates to 670.963, or 671 minus 1 divided by 27.)
|-
|    2  272013
| A nearly impossible to read date "format" that can be considered a parody "compromise" between different formats: rather than argue about the order in which the year, month, and day should be, they are simply all written on top of each other. As a "bonus", there is also no arguing over which separator character to use.
|-
| 10/11011/1101
| The US mm/dd/yy format in {{w|Binary number|binary}}, corresponding to 2/27/13. Never used for obvious reasons.
|-
| 02/27/20/13
| MM/DD/CC/YY, where CC stands for century. This format is never used. Note that while months and days count starting from 1, centuries and years in this format count from 0 for extra confusion. But the CC value is widely used on many operating systems to distinguish between the 20th and 21st century, represented by the values "19" and "20" because 1950 belongs to the 20th century.
|-
| 2053112674378
| An obfuscated format where the small numbers indicate the positions where the large digits should be placed. In this reading, 0 is used at positions 2 and 5, 1 is used on position 3, etc.; the result being 20130227

1643: Degrees

2016-02-15T21:49:14Z

SISenor:

{{comic
| number = 1643
| date = February 15, 2016
| title = Degrees
| image = degrees.png
| titletext = "Radians Fahrenheit or radians Celsius?" "Uh, sorry, gotta go!"
}}

==Explanation==
{{incomplete|First explanation}}
[[Cueball]] is being asked by a friend for the {{w|temperature}}. While he is checking his smartphone for the weather, he begins pondering what unit he should use when answering the question. (See below for [[#Cueball's reasoning|Cueball's reasoning]]).

In the US (where Cueball and [[Randall]] are from), the {{w|Conversion of units of temperature|temperature scale}} used in daily life is {{w|Fahrenheit}}. However, {{w|Celsius}} is commonly used for science, even in the US. Most of the rest of the world also uses Celsius in daily life.

:The Celsius scale is from the {{w|metric system}} which has been officially sanctioned for use in the US since 1866 , but it is most often not used in daily life, although it is the preferred system for trade and commerce according to the {{w|Metric Conversion Act}} of 1975. The US, however, remains the only industrialized country that has not adopted the metric system as its official system of measurement. The unit ''degree Celsius'' or °C is an accepted {{w|International_System_of_Units#Derived_units|derived unit}} from the {{w|International System of Units}} (SI units) used in science (which again is the modern form of the metric system). The SI unit of temperature is the {{w|Kelvin}}, but this temperature scale is linearly related to the Celsius scale, which is why Celsius can be derived from it.
:The Fahrenheit scale is from the {{w|United States customary units|US Customary system}}, often referred to as the {{w|Imperial_units|Imperial system}}. The unit is ''degree Fahrenheit'' or °F, and the relation to the Celsius scale is not easy to find in a mental calculation. The relations are: [°F] = [°C]*9⁄5 + 32 or [°C] = ([°F] − 32)×5⁄9.

Cueball weighs up the benefits of both, but is rushed by his friend to give an answer, so he gives the answer in {{w|radians}} (which can be denoted with the superscript c, but more commonly ㎭ or rad, lest it be confused with the ° for angular degrees), which is a system used to measure angular measure in geometry, not temperature gradations of whichever scale. Thus, this answer is unhelpful. Strictly speaking, a value given in radians doesn't have a unit, it's just a plain number (for an angle in geometry).

The joke here is that traditionally {{w|Angle|Geometrical angles}} are {{w|Triangle|measured in degrees}}, and temperature is measured in degrees (e.g. {{w|Celsius|degrees Celsius}}), but there is not the {{w|Degree|slightest degree}} of {{w|correlation}} between the two.

The title text indicates that Cueball's friend still wants to know whether the answer is in radians Fahrenheit or radians Celsius, which, despite being a silly way to express temperature, makes Cueball nervous, and he runs off. The answer Cueball gives is 0.173 radians, which is around 9.91 degrees. (9.91 °C = 49.8 °F and 9.91 °F = -12.3 °C.) Given the temperatures in Massachusetts (where Randall lives) when this comic came out, this was likely radians Fahrenheit.

===Cueball's reasoning===

{| class="wikitable"
| | Reason
| | Explanation
|-
| Degrees Celsius
|-
| |
International standard
| |
Degrees Celsius is derived unit in the SI system of units used to measure temperature in most countries today. Using the SI system would allow Cueball to be easily understood in most countries and is by far the most recognized system, but it is not the most commonly used in the United States, his actual location in the comic.

|-
| |
Helps reduce America's weird isolationism
| |
The United States uses its own set of units, including degrees Fahrenheit, called the {{w|United States customary units|United States Customary system}} and similar but not equal to the {{w|Imperial units|Imperial system}}, in contrast to most of the rest of the world which uses the SI system. The US's system of units is therefore considered "weird" as it makes the US different from most of the world for no good reason, but previous efforts to convert the US to the SI system have failed. Cueball evidently believes that by using SI units he will help to eventually convert the US to the SI system, bringing considerable trade and tourism benefits and reducing confusion when dealing with foreigners.
|-
| |
Nice how "negative" means below freezing
| |
On the Celsius scale, the freezing point of water at standard atmospheric pressure (101.325 kilopascals) is 0 °C, and any temperature below that is "below" the freezing point. On the Fahrenheit scale, the freezing point is a less memorable 32 °F.
|-
| |
Physics major loyalty
| |
Cueball is apparently a physics major, like Randall, and SI units are more commonly used for scientific work (as the Kelvin scale is sometimes used in advanced Physics), even in the US. By using the Celsius scale in casual conversation he would show his loyalty to the system used by actual physicists.
|-
| |
Easier to spell
| |
"Celsius" is generally considered to be an easier word to spell than "Fahrenheit." In this case the word is being spoken and the point is not immediately relevant, but part of the joke is that Cueball is overthinking things and worrying about the general use of the word when an answer is needed in this specific case.
|-
| |
We lost a Mars probe over this crap
| |
The {{w|Mars_Climate_Orbiter|Mars Climate Orbiter}} disintegrated in Mars' atmosphere because Lockheed used US Customary units instead of the contractually specified metric units.
|-
| | Degrees Fahrenheit
|-
| |
0°F to 100°F good match for temperature range in which most humans live
| |
While it makes sense to use Celsius temperatures for scientific or engineering measurements - or even cooking - where the freezing and boiling points of water (0 °C and 100 °C, respectively) are both significant, 0 °F and 100 °F correspond to "just about as cold as it gets" and "just about as hot as it gets" in temperate zones, thereby making Fahrenheit a useful temperature scale for weather reporting where most people live. By contrast, in Celsius a range of common temperatures in temperate zones is -20 °C to 40 °C, which is a less intuitive range for those used to the Fahrenheit scale.
|-
| |
Rounds more usefully (70's, 90's)
| |
An argument sometimes heard for the continued use of Fahrenheit temperatures is that each 10 degrees change is meaningful in how we feel the temperature. Thus, it is convenient to talk about the temperature being in the 70's today, or in the 90's, etc. Since the Celsius degrees are almost twice as large, a similar statement about the temperature being in the 20's or 30's is not as useful, unless more precision is added by using phrases like low 20's or high 30's. However, this seems likely to be more a matter of which scale you are used to using than anything inherent in one scale or the other.
|-
| |
Unit-aware computing makes Imperial less annoying
| |
If you need to constantly convert between Imperial and SI measurements in your head, or even between different Imperial units (e.g., ounces and pounds), it gets annoying and is a strong argument for everyone using metric measurements all the time. But, when it is easy to get the temperature - or any other measurement - reported in whatever units you want just by selecting the units you want your computer to report, then the annoyance is minimized, and the arguments for why we should stop using a familiar scale are weakened. Note that Cueball is looking at his smart-phone to get the current temperature.
|-
| |
SI prefixes are less relevant for temperatures
| |
One of the nice things about SI measurements is how the same basic unit scales by factors of 10 with common prefixes - e.g., kilometer, millimeter, kilogram, milligram, etc. Imperial measurements don't have this feature - you don't talk about long distances as kiloinches or small weights as millipounds. But, we generally don't use multiple units for atmospheric temperature (millidegrees or kilodegrees), so this argument for using SI measurements for length, mass, volume, etc., doesn't apply for temperature scales.
|-
| |
Fahrenheit is likely more clear in this context
| |
Cueball apparently knows that the inquirer is most likely to assume the answer will be in degrees Fahrenheit, so giving the answer that way would be the least likely to be misinterpreted. If he surprisingly gives an answer in Celsius, without explicitly stating he is reporting the temperature in Celsius, then that could be confusing.
|-
| |
Valuing unit standardization over being helpful possibly makes me a bad friend
| |
The final thing Cueball considers is to question why he would give an answer that attaches more value to promoting standardization of units when all his friend wants to know is whether it is cold or warm outside. Wouldn't it be more friendly to just answer the question the way his friend will find most convenient?

Helps reduce America's weird isolationism
| |
The United States uses its own set of units, including degrees Fahrenheit, called the {{w|United States customary units|United States Customary system}} and similar but not equal to the {{w|Imperial units|Imperial system}}, in contrast to most of the rest of the world which uses the SI system. The US's system of units is therefore considered "weird" as it makes the US different from most of the world for no good reason, but previous efforts to convert the US to the SI system have failed. Cueball evidently believes that by using SI units he will help to eventually convert the US to the SI system, bringing considerable trade and tourism benefits and reducing confusion when dealing with foreigners.
|-
| |
Nice how "negative" means below freezing
| |
On the Celsius scale, the freezing point of water at standard atmospheric pressure (101.325 kilopascals) is 0 °C, and any temperature below that is "below" the freezing point. On the Fahrenheit scale, the freezing point is a less memorable 32 °F.
|-
| |
Physics major loyalty
| |
Cueball is apparently a physics major, like Randall, and SI units are more commonly used for scientific work (as the Kelvin scale is sometimes used in advanced Physics), even in the US. By using the Celsius scale in casual conversation he would show his loyalty to the system used by actual physicists.
|-
| |
Easier to spell
| |
"Celsius" is generally considered to be an easier word to spell than "Fahrenheit." In this case the word is being spoken and the point is not immediately relevant, but part of the joke is that Cueball is overthinking things and worrying about the general use of the word when an answer is needed in this specific case.

| |
0°F to 100°F good match for temperature range in which most humans live
| |
While it makes sense to use Celsius temperatures for scientific or engineering measurements - or even cooking - where the freezing and boiling points of water (0 °C and 100 °C, respectively) are both significant, 0 °F and 100 °F correspond to "just about as cold as it gets" and "just about as hot as it gets" in temperate zones, thereby making Fahrenheit a useful temperature scale for weather reporting where most people live. By contrast, in Celsius a range of common temperatures in temperate zones is -20 °C to 40 °C, which is a less intuitive range for those used to the Fahrenheit scale.
|-
| |
Rounds more usefully (70's, 90's)
| |
An argument sometimes heard for the continued use of Fahrenheit temperatures is that each 10 degrees change is meaningful in how we feel the temperature. Thus, it is convenient to talk about the temperature being in the 70's today, or in the 90's, etc. Since the Celsius degrees are almost twice as large, a similar statement about the temperature being in the 20's or 30's is not as useful, unless more precision is added by using phrases like low 20's or high 30's. However, this seems likely to be more a matter of which scale you are used to using than anything inherent in one scale or the other.
|-
| |
Unit-aware computing makes Imperial less annoying
| |
If you need to constantly convert between Imperial and SI measurements in your head, or even between different Imperial units (e.g., ounces and pounds), it gets annoying and is a strong argument for everyone using metric measurements all the time. But, when it is easy to get the temperature - or any other measurement - reported in whatever units you want just by selecting the units you want your computer to report, then the annoyance is minimized, and the arguments for why we should stop using a familiar scale are weakened. Note that Cueball is looking at his smart-phone to get the current temperature.
|-
| |
SI prefixes are less relevant for temperatures
| |
One of the nice things about SI measurements is how the same basic unit scales by factors of 10 with common prefixes - e.g., kilometer, millimeter, kilogram, milligram, etc. Imperial measurements don't have this feature - you don't talk about long distances as kiloinches or small weights as millipounds. But, we generally don't use multiple units for atmospheric temperature (millidegrees or kilodegrees), so this argument for using SI measurements for length, mass, volume, etc., doesn't apply for temperature scales.
|-
| |
Fahrenheit is likely more clear in this context
| |
Cueball apparently knows that the inquirer is most likely to assume the answer will be in degrees Fahrenheit, so giving the answer that way would be the least likely to be misinterpreted. If he surprisingly gives an answer in Celsius, without explicitly stating he is reporting the temperature in Celsius, then that could be confusing.
|-
| |
Valuing unit standardization over being helpful possibly makes me a bad friend
| |
The final thing Cueball considers is to question why he would give an answer that attaches more value to promoting standardization of units when all his friend wants to know is whether it is cold or warm outside. Wouldn't it be more friendly to just answer the question the way his friend will find most convenient?

1643: Degrees

2016-02-15T20:52:15Z

SISenor:

{{comic
| number = 1643
| date = February 15, 2016
| title = Degrees
| image = degrees.png
| titletext = "Radians Fahrenheit or radians Celsius?" "Uh, sorry, gotta go!"
}}

==Explanation==
{{incomplete|First explanation}}
[[Cueball]] is being asked by a friend for the temperature. There are two common ways to give this: in degrees Celsius and degrees Fahrenheit. The former is the {{w |Metric_system|metric system}}, most often not used in the US although it is {{w|Metric_Conversion_Act|the preferred system for trade and commerce}}. The latter is the {{w|United States customary units|US Customary system}}, often referred to as the {{w|Imperial_units|Imperial system}}. Cueball weighs up the benefits of both, but is rushed by his friend to give an answer, so he gives the answer in {{w|radians}} (which can be denoted with the superscript c, but more commonly ㎭ or rad, lest it be confused with the ° for angular degrees), which is a system used to measure angular measure in geometry, not temperature gradations of whichever scale. Thus, this answer is unhelpful. Strictly speaking, a value given in radians doesn't have a unit, it's just a plain number (for an angle in geometry).

The joke here is that traditionally {{w|Angle|Geometrical angles}} are {{w|Triangle|measured in degrees}}, and temperature is measured in degrees (e.g. {{w|Celsius|degrees celsius}} ), but there is not the {{w|Degree|slightest degree}} of {{w|correlation}} between the two.

The title text indicates that Cueball's friend still wants to know whether the answer is in radians Fahrenheit or radians Celsius, which, despite being a silly way to express temperature, makes Cueball nervous, and he runs off. The answer Cueball gives is 0.173 radians, which is around 9.91 degrees. (9.91°C = 49.8°F and 9.91°F = -12.3°C). Given the temperatures in Massachusetts (where Randall lives) when this comic came out, this was likely radians Fahrenheit.

===Summary of Reasons===

{| class="wikitable"
| | Reason
| | Explanation
|-
| |
International standard
| |
Degrees Celsius is derived unit in the SI system of units used to measure temperature in most countries today. Using the SI system would allow Cueball to be easily understood in most countries and is by far the most recognized system, but it is not the most commonly used in the United States, his actual location in the comic.

|-
| |
Helps reduce America's weird isolationism
| |
The United States uses its own set of units, including Degrees Fahrenheit, called the {{w|United_States_customary_units}} and based on {{w|Imperial units}}, in contrast to most of the rest of the world which uses the SI system. The US's system of units is therefore considered "weird" as it makes the US different from most of the world for no good reason, but previous efforts to convert the US to the SI system have failed. Cueball evidently believes that by using SI units he will help to eventually convert the US to the SI system, bringing considerable trade and tourism benefits and reducing confusion when dealing with foreigners.

526: Converting to Metric

2016-02-15T20:07:59Z

SISenor: *sigh* Missed one space.

{{comic
| number = 526
| date = January 5, 2009
| title = Converting to Metric
| image = converting to metric.png
| titletext = According to River, "adequate" vacuuming systems drain the human body at about half a liter per second.
}}
==Explanation==
Most people will eventually develop an intuitive feel for how big certain measurements are (e.g., how long an inch or a foot is, how much a pound weighs). This comic points out that people who were brought up using the {{w|United States customary units|United States system of customary units}} probably don't have the same intuitive understanding for metric units and attempts to provide some benchmarks for these people. Most of the benchmarks are common sense, highly-useful ones (e.g., if it's 30 degrees Celsius [86 °F], you'd be quite comfortable outside dressed for the beach) but some of the benchmarks are humorous and/or completely useless. Benchmarks include:

===Temperature===
* {{w|Extremes on Earth|Earth's hottest}}: 60⁠ °C [140 °F]: The hottest temperature recorded on earth is actually {{W|List_of_weather_records#Heat|"only" 56.7 °C}}. There have been reports of ten-twenty degrees higher (70-80 ⁠°C) but these measurements are not verified or accepted as world records.
* Various heat waves: {{w|Dubai}} is a city in the United Arab Emirates, and is smack-dab in the middle of an equatorial desert, so their heat waves can get ''hot!''. The southern Unites States will typically be a few degrees hotter than the northern United States simply because it's closer to the equator, but as mentioned they're both above "Beach Weather".
*30 °C [86 °F]: A little too hot so perfect for a trip to the beach.
*20 °C [68 °F]: Is defined as room temperature in many experimental settings. For some this would feel a little cool. But 25 °C [77 °F] would as mentioned be too warm for room temperature...
*10 °C [50 °F]: Definitely wear a jacket. Especially if there is just a little breeze.
*0⁠ °C [32 °F]: The freezing point of water (32 °⁠F).
*-5 to -10 °C: In Moscow -10 °C is not really that cold - it can go "spit goes clink" cold in {{W|Moscow#Climate|Moscow}}, whereas -5 °C [23 °F] in {{W|Boston#Climate|Boston}} may be very cold...
*-20 °C: FuckFuckFuckCold and -30 °C - Fuuuuuuuuuuuuck!: This is implied to be basically what some people would say when they step outside at this temperature. In reality, it would be best to keep ones's mouth firmly closed. At -30 °C, without taking wind chill into account, exposed skin will feel painful in under a minute and frostbite could begin in as little as ten minutes [http://www.ec.gc.ca/meteo-weather/default.asp?lang=En&n=5FBF816A-1]. The differing statements seem to imply that at -20 °C, the user would be saying "fuck" repeatedly, whereas at -30 °C, the user is incapable of closing their mouth after starting the first "fuck", and so extends it into one long one.
*-40⁠ °C: Spit goes "clink": As shown in the drawing your spit would freeze ''before'' it hits the ground. This is the crossing point of the two temperature scales i.e. -40 °C = -40 °F.

===Length===
*1 cm [.4 inch] : Width of microSD card and 3 cm - Length of SD card: Refers to the {{w|MicroSD card|memory cards}} used in cell phones, digital cameras, etc.
*12 cm [almost 5 inches]: CD-ROM is a common object so nice to know it is a dozen centimeters.
*14 cm [5 1/2 inches]: Most males would probably exaggerate the size of their penis, but 14–15 cm is very average.
*15 cm [almost 6 inches]: A Bic pen
*80 cm [31 1/2 inches]: A typical doorway is also of standard size. This is barely over the minimum size typically required by codes for buildings [30 inches or 76.2 cm], but more than 50% over the size required for aircraft emergency exits. (It may seem illogical that larger doors are required in buildings than in airplanes, given airplanes are arguably more dangerous. However, there is no real disadvantage to using larger doors in buildings, which are not significantly pressurized, but using larger doors in aircraft would increase the force on the door caused by cabin pressure proportionally.)
*1 m [39.37 inches]: {{w|Lightsaber|Lightsaber blade}}: Refers the weapon used in the {{w|Star Wars}} movie franchise. Canonically, the length of a lightsaber's blade varies greatly depending on the setting of the weapon, but "one meter" is by no means a bad approximation.
*170 cm [5 feet, 7 inches]: {{w|Summer Glau}}: Refers to the height of the actress who portrays the character River Tam on the TV show {{w|Firefly (TV series)|Firefly}}.
*200 cm [6 feet, 6 and 3/4 inches]: Darth Vader: Refers to the height of the main antagonist from Star Wars.
*2.5 m [a little over 8 feet]: Ceiling - of course very much depending on which type of building you are in!
*5 m [a little over 16 feet]: Car length - also very much depending on the car...
*16 m 4 cm: Human tower of Serenity crew: Again, this refers to the Firefly TV show, which takes place mostly on a space ship called Serenity.
**Presumably, if all the crew of Serenity were stacked on top of each other, this would be their combined height.
**The comic depicts four characters from the show standing on top of each other; the bottom figure is the crew's captain, {{w|Malcolm Reynolds}} in his signature coat. Judging from the other drawing of Summer Glau from the volume section, she is standing on top of the captain.
**The other five members of the crew should also be stacked on top of these four to reach the 16 m height - giving them an average height of 1.82 m (12 cm more than Summer Glaus height!)

===Speed===
:Here both the SI unit m/s as well as the more used unit kph (kilometers per hour, km/h) is given.
*5 kph [3 mph] - 1.5 m/s: Walking at a normal pace
*13-25 kph [8-15 mph]: Jogging to sprinting.
*35 kph [21.75 mph] - 10 m/s: Fastest human: As of 2009, the fastest a human has been recorded to run in a single sprint is actually 45 kph, a record set by {{w|Usain Bolt}}.
*45-55 kph: Both cats and rabbits go much faster than normal people.
*75 kph [46.6 mph] - 20 m/s: Raptor: It's a comic written by [[Randall]], of course a reference to the {{w|velociraptors}} from ''{{w|Jurassic Park (film)|Jurassic Park}}'' was going to be here.
*100 kph - 25 m/s: A slow highway (62 mph).
*110 kph [68.35 mph] - 30 m/s: Interstate (65 mph): Refers to the {{w|Interstate|American highway system}}. (65 mph would actually be only 104.6 kph.)
*120 kph - 35 m/s: Speed you actually go when it says "65": People routinely break the aforementioned speed limit, and the police typically don't mind as long as it's not posing any danger. For the record, 120 kph is 74 mph.
*140 kph - 40 m/s (87-89 mph): Raptor on hoverboard: The {{w|hoverboard}} is probably a reference to the ''{{w|Back to the Future Part II}}'', though it's a fairly common trope in older science fiction stories. Randall obviously did a lot of google searching on this subject the week before - see [[522: Google Trends]].

===Volume===
*3 mL: The amount of blood in a fieldmouse. A similar amount is used in comic [[434: xkcd Goes to the Airport]], but instead of a fieldmouse, the measurement of blood is of a churchmouse, an imaginary animal created by Lewis Carroll. Click [[434: xkcd Goes to the Airport|here]] for a more on [[434: xkcd Goes to the Airport|comic 434]].
*5 mL: A teaspoon - a very common measure.
*30 mL: Nasal passages and 40 mL - Shot glass: The comic points out that you could just about fill a shot glass using the mucus from your nose. Since shot glasses are usually used for mixed drinks, the comic jokes that this mucus could constitute a new, disgusting drink - and this is depicted in the drawing.
*350 mL: Soda can (this is roughly correct for the cans used in the U.S., which hold 12 fluid ounces; in Europe, soda cans commonly hold 330 mL or 500 mL).
*500 mL: Water bottle (this is the also the volume of a European water bottle).
*3 L: Two-liter bottle: Refers to a bottle which contains two liters (in the US usually soda). There is debate as to the reason for the discrepancy in volume. It may be a reference to stereotypical Americans consuming a lot of high-calorie foods and drinks. The simpler explanation would be that it is a joke. The two-liter bottle is named using its volume. Labeling it with a volume of three liters is the joke.
*5 L: An adult male has about 5 L of blood in his body (An ''adequate'' vacuuming system could drain this blood out in 10 s - as per the title text!)
*30 L: Milk crate: Refers to a {{w|Milk crate|type of small box}} originally used to transport milk but now often in demand to be used as bicycle basket, storage spaces, etc.
*55 L: Summer Glau: Again, this refers to the actress from Firefly.
*65 L: {{w|Dennis Kucinich}}: An American politician belonging to the {{w|Democratic Party (United States)|Democratic party}}, noted for his relatively strong (for the US) leftist views.
*75 L: {{w|Ron Paul}}: An American politician belonging to the rival {{w|Republican Party (United States)|Republican party}}, noted for his strong rightist views.
*200 L: Volume of refrigerator.
*As shown in the drawing of this part of the comic, the three persons mentioned above - Glau, Kucinich and Paul (summing up to 195 L) - could in principle all fit inside a standard refrigerator. Cueball thus attempts to push them all inside of one - though it would obviously be very uncomfortable for all parties involved to be trapped in such a small space with not much room between them (not to mention practically impossible).

===Mass===
*3 g: {{w|M&M's|Peanut M&M}}: A small chocolate candy with a peanut inside
*100 g: Cell phone - this very much depends on the age of the cell phone, and the type etc.
*500 g [1 lb.]: A bottle of water contains 500 mL according to the volume section and thus have mass of 500 g.
*1–3 kg: Different types of laptops. The newest and the best is the lightest...
*5 kg [11 lb.]: {{w|LCD monitor}}: A modern flat-screen-style monitor.
*15 kg: {{w|CRT monitor}}: An older-style, cathode ray tube-based monitor.
**This ends the section on computer screens, which overrode the normal sequence by weight as the next two feline inspired entries are lighter than the two before. This was presumably done so that the reader's eye will be confused or amused at seeing (in the comic's caseless captioning font) CRT immediately followed by CAT in the vertical text column.
*4 kg: Cat and 4.1 kg - Cat (with caption): Refers to the internet's love of putting {{w|Lolcat|captions on cats}}. Usually, this is done in a graphics program, but here the cat is actually physically carrying around his caption. The "with caption" part is most likely a reference to [[262: IN UR REALITY]], where [[Black Hat]] glues captions to cats, after running out of staples.
*60 kg [130 lb.]: Lady - for instance if she is Summer Glau - could be her again depicted in the comic - average weight of an adult woman.
*70 kg [150 lb.]: Dude - here depicted as Cueball who is the average guy, and 70 kg is average weight for an adult man.
*150 kg: Shaq: {{w|Shaq|Shaquille O'Neal}}, a famously tall basketball player.
*200 kg [440 lb.]: Your mom
*220 kg: Your mom (incl. 20 kg of cheap jewelry) and
*223 kg: Your mom (also incl. 3 kg of makeup)
*The last three refer to a common type of {{w|Your mom}} joking insult whereby someone insults someone else's mother in a creative way. Here, the comic slyly calls your mom fat, then implies she wears way too much jewelry and finally also almost 7 pounds of makeup. This is a common theme in [http://www.explainxkcd.com/wiki/index.php/Category:Your_Mom xkcd]. (20 kg of "cheap" jewelry has several times the volume than 20 kg of gold jewelry, because of the difference in density.)

===Title text===
The title text refers once again to Summer Glau's Firefly character, {{w|River Tam}}, who (after being subjected to a long series of medical experiments) is severely mentally ill and often comes out with macabre — though scientifically accurate — pronouncements. In Firefly episode "Safe" (season 1, episode 7), she says: "The human body can be drained of blood in 8.6 seconds given adequate vacuuming systems."

526: Converting to Metric

2016-02-15T20:02:30Z

SISenor: Missed one "L"

{{comic
| number = 526
| date = January 5, 2009
| title = Converting to Metric
| image = converting to metric.png
| titletext = According to River, "adequate" vacuuming systems drain the human body at about half a liter per second.
}}
==Explanation==
Most people will eventually develop an intuitive feel for how big certain measurements are (e.g., how long an inch or a foot is, how much a pound weighs). This comic points out that people who were brought up using the {{w|United States customary units|United States system of customary units}} probably don't have the same intuitive understanding for metric units and attempts to provide some benchmarks for these people. Most of the benchmarks are common sense, highly-useful ones (e.g., if it's 30 degrees Celsius [86 °F], you'd be quite comfortable outside dressed for the beach) but some of the benchmarks are humorous and/or completely useless. Benchmarks include:

===Temperature===
* {{w|Extremes on Earth|Earth's hottest}}: 60⁠ °C [140 °F]: The hottest temperature recorded on earth is actually {{W|List_of_weather_records#Heat|"only" 56.7 °C}}. There have been reports of ten-twenty degrees higher (70-80 ⁠°C) but these measurements are not verified or accepted as world records.
* Various heat waves: {{w|Dubai}} is a city in the United Arab Emirates, and is smack-dab in the middle of an equatorial desert, so their heat waves can get ''hot!''. The southern Unites States will typically be a few degrees hotter than the northern United States simply because it's closer to the equator, but as mentioned they're both above "Beach Weather".
*30 °C [86 °F]: A little too hot so perfect for a trip to the beach.
*20 °C [68 °F]: Is defined as room temperature in many experimental settings. For some this would feel a little cool. But 25 °C [77 °F] would as mentioned be too warm for room temperature...
*10 °C [50 °F]: Definitely wear a jacket. Especially if there is just a little breeze.
*0⁠ °C [32 °F]: The freezing point of water (32 °⁠F).
*-5 to -10 °C: In Moscow -10 °C is not really that cold - it can go "spit goes clink" cold in {{W|Moscow#Climate|Moscow}}, whereas -5 °C [23 °F] in {{W|Boston#Climate|Boston}} may be very cold...
*-20 °C: FuckFuckFuckCold and -30 °C - Fuuuuuuuuuuuuck!: This is implied to be basically what some people would say when they step outside at this temperature. In reality, it would be best to keep ones's mouth firmly closed. At -30 °C, without taking wind chill into account, exposed skin will feel painful in under a minute and frostbite could begin in as little as ten minutes [http://www.ec.gc.ca/meteo-weather/default.asp?lang=En&n=5FBF816A-1]. The differing statements seem to imply that at -20 °C, the user would be saying "fuck" repeatedly, whereas at -30 °C, the user is incapable of closing their mouth after starting the first "fuck", and so extends it into one long one.
*-40⁠ °C: Spit goes "clink": As shown in the drawing your spit would freeze ''before'' it hits the ground. This is the crossing point of the two temperature scales i.e. -40 °C = -40 °F.

===Length===
*1 cm [.4 inch] : Width of microSD card and 3 cm - Length of SD card: Refers to the {{w|MicroSD card|memory cards}} used in cell phones, digital cameras, etc.
*12 cm [almost 5 inches]: CD-ROM is a common object so nice to know it is a dozen centimeters.
*14 cm [5 1/2 inches]: Most males would probably exaggerate the size of their penis, but 14–15 cm is very average.
*15 cm [almost 6 inches]: A Bic pen
*80 cm [31 1/2 inches]: A typical doorway is also of standard size. This is barely over the minimum size typically required by codes for buildings [30 inches or 76.2 cm], but more than 50% over the size required for aircraft emergency exits. (It may seem illogical that larger doors are required in buildings than in airplanes, given airplanes are arguably more dangerous. However, there is no real disadvantage to using larger doors in buildings, which are not significantly pressurized, but using larger doors in aircraft would increase the force on the door caused by cabin pressure proportionally.)
*1 m [39.37 inches]: {{w|Lightsaber|Lightsaber blade}}: Refers the weapon used in the {{w|Star Wars}} movie franchise. Canonically, the length of a lightsaber's blade varies greatly depending on the setting of the weapon, but "one meter" is by no means a bad approximation.
*170 cm [5 feet, 7 inches]: {{w|Summer Glau}}: Refers to the height of the actress who portrays the character River Tam on the TV show {{w|Firefly (TV series)|Firefly}}.
*200 cm [6 feet, 6 and 3/4 inches]: Darth Vader: Refers to the height of the main antagonist from Star Wars.
*2.5 m [a little over 8 feet]: Ceiling - of course very much depending on which type of building you are in!
*5 m [a little over 16 feet]: Car length - also very much depending on the car...
*16 m 4 cm: Human tower of Serenity crew: Again, this refers to the Firefly TV show, which takes place mostly on a space ship called Serenity.
**Presumably, if all the crew of Serenity were stacked on top of each other, this would be their combined height.
**The comic depicts four characters from the show standing on top of each other; the bottom figure is the crew's captain, {{w|Malcolm Reynolds}} in his signature coat. Judging from the other drawing of Summer Glau from the volume section, she is standing on top of the captain.
**The other five members of the crew should also be stacked on top of these four to reach the 16 m height - giving them an average height of 1.82 m (12 cm more than Summer Glaus height!)

===Speed===
:Here both the SI unit m/s as well as the more used unit kph (kilometers per hour, km/h) is given.
*5 kph [3 mph] - 1.5 m/s: Walking at a normal pace
*13-25 kph [8-15 mph]: Jogging to sprinting.
*35 kph [21.75 mph] - 10 m/s: Fastest human: As of 2009, the fastest a human has been recorded to run in a single sprint is actually 45 kph, a record set by {{w|Usain Bolt}}.
*45-55 kph: Both cats and rabbits go much faster than normal people.
*75 kph [46.6 mph] - 20 m/s: Raptor: It's a comic written by [[Randall]], of course a reference to the {{w|velociraptors}} from ''{{w|Jurassic Park (film)|Jurassic Park}}'' was going to be here.
*100 kph - 25 m/s: A slow highway (62 mph).
*110 kph [68.35 mph] - 30 m/s: Interstate (65 mph): Refers to the {{w|Interstate|American highway system}}. (65 mph would actually be only 104.6 kph.)
*120 kph - 35 m/s: Speed you actually go when it says "65": People routinely break the aforementioned speed limit, and the police typically don't mind as long as it's not posing any danger. For the record, 120 kph is 74 mph.
*140 kph - 40 m/s (87-89 mph): Raptor on hoverboard: The {{w|hoverboard}} is probably a reference to the ''{{w|Back to the Future Part II}}'', though it's a fairly common trope in older science fiction stories. Randall obviously did a lot of google searching on this subject the week before - see [[522: Google Trends]].

===Volume===
*3 mL: The amount of blood in a fieldmouse. A similar amount is used in comic [[434: xkcd Goes to the Airport]], but instead of a fieldmouse, the measurement of blood is of a churchmouse, an imaginary animal created by Lewis Carroll. Click [[434: xkcd Goes to the Airport|here]] for a more on [[434: xkcd Goes to the Airport|comic 434]].
*5 mL: A teaspoon - a very common measure.
*30 mL: Nasal passages and 40mL - Shot glass: The comic points out that you could just about fill a shot glass using the mucus from your nose. Since shot glasses are usually used for mixed drinks, the comic jokes that this mucus could constitute a new, disgusting drink - and this is depicted in the drawing.
*350 mL: Soda can (this is roughly correct for the cans used in the U.S., which hold 12 fluid ounces; in Europe, soda cans commonly hold 330 mL or 500 mL).
*500 mL: Water bottle (this is the also the volume of a European water bottle).
*3 L: Two-liter bottle: Refers to a bottle which contains two liters (in the US usually soda). There is debate as to the reason for the discrepancy in volume. It may be a reference to stereotypical Americans consuming a lot of high-calorie foods and drinks. The simpler explanation would be that it is a joke. The two-liter bottle is named using its volume. Labeling it with a volume of three liters is the joke.
*5 L: An adult male has about 5 L of blood in his body (An ''adequate'' vacuuming system could drain this blood out in 10 s - as per the title text!)
*30 L: Milk crate: Refers to a {{w|Milk crate|type of small box}} originally used to transport milk but now often in demand to be used as bicycle basket, storage spaces, etc.
*55 L: Summer Glau: Again, this refers to the actress from Firefly.
*65 L: {{w|Dennis Kucinich}}: An American politician belonging to the {{w|Democratic Party (United States)|Democratic party}}, noted for his relatively strong (for the US) leftist views.
*75 L: {{w|Ron Paul}}: An American politician belonging to the rival {{w|Republican Party (United States)|Republican party}}, noted for his strong rightist views.
*200 L: Volume of refrigerator.
*As shown in the drawing of this part of the comic, the three persons mentioned above - Glau, Kucinich and Paul (summing up to 195 L) - could in principle all fit inside a standard refrigerator. Cueball thus attempts to push them all inside of one - though it would obviously be very uncomfortable for all parties involved to be trapped in such a small space with not much room between them (not to mention practically impossible).

===Mass===
*3 g: {{w|M&M's|Peanut M&M}}: A small chocolate candy with a peanut inside
*100 g: Cell phone - this very much depends on the age of the cell phone, and the type etc.
*500 g [1 lb.]: A bottle of water contains 500 mL according to the volume section and thus have mass of 500 g.
*1–3 kg: Different types of laptops. The newest and the best is the lightest...
*5 kg [11 lb.]: {{w|LCD monitor}}: A modern flat-screen-style monitor.
*15 kg: {{w|CRT monitor}}: An older-style, cathode ray tube-based monitor.
**This ends the section on computer screens, which overrode the normal sequence by weight as the next two feline inspired entries are lighter than the two before. This was presumably done so that the reader's eye will be confused or amused at seeing (in the comic's caseless captioning font) CRT immediately followed by CAT in the vertical text column.
*4 kg: Cat and 4.1 kg - Cat (with caption): Refers to the internet's love of putting {{w|Lolcat|captions on cats}}. Usually, this is done in a graphics program, but here the cat is actually physically carrying around his caption. The "with caption" part is most likely a reference to [[262: IN UR REALITY]], where [[Black Hat]] glues captions to cats, after running out of staples.
*60 kg [130 lb.]: Lady - for instance if she is Summer Glau - could be her again depicted in the comic - average weight of an adult woman.
*70 kg [150 lb.]: Dude - here depicted as Cueball who is the average guy, and 70 kg is average weight for an adult man.
*150 kg: Shaq: {{w|Shaq|Shaquille O'Neal}}, a famously tall basketball player.
*200 kg [440 lb.]: Your mom
*220 kg: Your mom (incl. 20 kg of cheap jewelry) and
*223 kg: Your mom (also incl. 3 kg of makeup)
*The last three refer to a common type of {{w|Your mom}} joking insult whereby someone insults someone else's mother in a creative way. Here, the comic slyly calls your mom fat, then implies she wears way too much jewelry and finally also almost 7 pounds of makeup. This is a common theme in [http://www.explainxkcd.com/wiki/index.php/Category:Your_Mom xkcd]. (20 kg of "cheap" jewelry has several times the volume than 20 kg of gold jewelry, because of the difference in density.)

===Title text===
The title text refers once again to Summer Glau's Firefly character, {{w|River Tam}}, who (after being subjected to a long series of medical experiments) is severely mentally ill and often comes out with macabre — though scientifically accurate — pronouncements. In Firefly episode "Safe" (season 1, episode 7), she says: "The human body can be drained of blood in 8.6 seconds given adequate vacuuming systems."

526: Converting to Metric

2016-02-15T20:00:31Z

*120 kph - 35 m/s: Speed you actually go when it says "65": People routinely break the aforementioned speed limit, and the police typically don't mind as long as it's not posing any danger. For the record, 120 kph is 74 mph.
*140 kph - 40 m/s (87-89 mph): Raptor on hoverboard: The {{w|hoverboard}} is probably a reference to the ''{{w|Back to the Future Part II}}'', though it's a fairly common trope in older science fiction stories. Randall obviously did a lot of google searching on this subject the week before - see [[522: Google Trends]].

===Volume===
*3 mL: The amount of blood in a fieldmouse. A similar amount is used in comic [[434: xkcd Goes to the Airport]], but instead of a fieldmouse, the measurement of blood is of a churchmouse, an imaginary animal created by Lewis Carroll. Click [[434: xkcd Goes to the Airport|here]] for a more on [[434: xkcd Goes to the Airport|comic 434]].

*30 mL: Nasal passages and 40mL - Shot glass: The comic points out that you could just about fill a shot glass using the mucus from your nose. Since shot glasses are usually used for mixed drinks, the comic jokes that this mucus could constitute a new, disgusting drink - and this is depicted in the drawing.
*350 mL: Soda can (this is roughly correct for the cans used in the U.S., which hold 12 fluid ounces; in Europe, soda cans commonly hold 330 mL or 500 mL).
*500 ml: Water bottle (this is the also the volume of a European water bottle).
*3 L: Two-liter bottle: Refers to a bottle which contains two liters (in the US usually soda). There is debate as to the reason for the discrepancy in volume. It may be a reference to stereotypical Americans consuming a lot of high-calorie foods and drinks. The simpler explanation would be that it is a joke. The two-liter bottle is named using its volume. Labeling it with a volume of three liters is the joke.
*5 L: An adult male has about 5 L of blood in his body (An ''adequate'' vacuuming system could drain this blood out in 10 s - as per the title text!)
*30 L: Milk crate: Refers to a {{w|Milk crate|type of small box}} originally used to transport milk but now often in demand to be used as bicycle basket, storage spaces, etc.
*55 L: Summer Glau: Again, this refers to the actress from Firefly.
*65 L: {{w|Dennis Kucinich}}: An American politician belonging to the {{w|Democratic Party (United States)|Democratic party}}, noted for his relatively strong (for the US) leftist views.
*75 L: {{w|Ron Paul}}: An American politician belonging to the rival {{w|Republican Party (United States)|Republican party}}, noted for his strong rightist views.
*200 L: Volume of refrigerator.
*As shown in the drawing of this part of the comic, the three persons mentioned above - Glau, Kucinich and Paul (summing up to 195 L) - could in principle all fit inside a standard refrigerator. Cueball thus attempts to push them all inside of one - though it would obviously be very uncomfortable for all parties involved to be trapped in such a small space with not much room between them (not to mention practically impossible).

===Mass===
*3 g: {{w|M&M's|Peanut M&M}}: A small chocolate candy with a peanut inside
*100 g: Cell phone - this very much depends on the age of the cell phone, and the type etc.
*500 g [1 lb.]: A bottle of water contains 500 mL according to the volume section and thus have mass of 500 g.
*1–3 kg: Different types of laptops. The newest and the best is the lightest...
*5 kg [11 lb.]: {{w|LCD monitor}}: A modern flat-screen-style monitor.
*15 kg: {{w|CRT monitor}}: An older-style, cathode ray tube-based monitor.
**This ends the section on computer screens, which overrode the normal sequence by weight as the next two feline inspired entries are lighter than the two before. This was presumably done so that the reader's eye will be confused or amused at seeing (in the comic's caseless captioning font) CRT immediately followed by CAT in the vertical text column.
*4 kg: Cat and 4.1 kg - Cat (with caption): Refers to the internet's love of putting {{w|Lolcat|captions on cats}}. Usually, this is done in a graphics program, but here the cat is actually physically carrying around his caption. The "with caption" part is most likely a reference to [[262: IN UR REALITY]], where [[Black Hat]] glues captions to cats, after running out of staples.
*60 kg [130 lb.]: Lady - for instance if she is Summer Glau - could be her again depicted in the comic - average weight of an adult woman.
*70 kg [150 lb.]: Dude - here depicted as Cueball who is the average guy, and 70 kg is average weight for an adult man.
*150 kg: Shaq: {{w|Shaq|Shaquille O'Neal}}, a famously tall basketball player.
*200 kg [440 lb.]: Your mom
*220 kg: Your mom (incl. 20 kg of cheap jewelry) and
*223 kg: Your mom (also incl. 3 kg of makeup)
*The last three refer to a common type of {{w|Your mom}} joking insult whereby someone insults someone else's mother in a creative way. Here, the comic slyly calls your mom fat, then implies she wears way too much jewelry and finally also almost 7 pounds of makeup. This is a common theme in [http://www.explainxkcd.com/wiki/index.php/Category:Your_Mom xkcd]. (20 kg of "cheap" jewelry has several times the volume than 20 kg of gold jewelry, because of the difference in density.)

===Title text===
The title text refers once again to Summer Glau's Firefly character, {{w|River Tam}}, who (after being subjected to a long series of medical experiments) is severely mentally ill and often comes out with macabre — though scientifically accurate — pronouncements. In Firefly episode "Safe" (season 1, episode 7), she says: "The human body can be drained of blood in 8.6 seconds given adequate vacuuming systems."

:'''Guide to Converting to Metric'''

:"that's warmer than a house but cool for swimming."
