==Explanation==
{{incomplete|Created by THOR, GOD OF THUNDER. Add the equation for throwing, done... Now explain them (what is the unit of the dragC and how does it work)? Could we add the animation of the throwers? Transcript of the possible sentences in a table on an extra page/possible pictures also. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This is an interactive comic made to celebrate the release of [[Randall|Randall's]] new book, ''[[How To]]''. The comic is based on a chapter in the book. 

As the comic celebrates the book, which was released on Tuesday, September 3rd, 2019, the comic was thus also released on a [[:Category:Tuesday comics|Tuesday]] to coincide with the release day, replacing that week's normal Wednesday release. This was the same timing used for another of Randall's book releases, when [[1608: Hoverboard]] came out on the Tuesday when [[Thing Explainer]] came out. Although the Hoverboard comic is much more complex than this one, they are both [[:Category:Dynamic comics|dynamic]] and [[:Category:Interactive comics|interactive]], with [[:Category:Comics with animation|animations]] a part of them. Also the  [[xkcd Header text]] changed to [[xkcd_Header_text#2019-09-04_-_Happy_Release_Day_-_bookstore|promote the release]] creating a large [https://www.explainxkcd.com/wiki/images/0/08/2198_Throw_-_Front_page_promotion.PNG combined promotion] of the book during the three full days the comic was on the front page (see more [[2198:_Throw/Screen-shots#Entire_xkcd_page_with_promotion|here]]).

In this comic the viewer can select a thrower and an object to be thrown, see this [[#Throwers and throw items|table]], and get an [[2198:_Throw/Screen-shots#Animation|animation]] of how the selected throw would work out, along with an estimated distance of the throw (both in the SI unit meter (m) and in other very arbitrary units; see this [[#Table of distance units|table]] below) if the throw was possible. Impossible throws include those where the thrower is not strong enough to thrown object, or when the thrower tries to throw themselves, which is possible as four "objects" are also listed as throwers, most prominently {{w|George Washington}}. As the comic picture above cannot show all the possible selections in the two windows, pictures of all can be found [[2198:_Throw/Screen-shots#Throwers_and_Objects|here]]

The formula/guideline is apparently based on chapter 10 from the new ''How to'' book, see more under [[#Formulas|Formulas]]. 

It seemed though, that there was a special case to the calculations with {{w|Thor|Thor's}} hammer ({{w|Mjolnir}}). Because this comic obviously refers to the {{w|Thor (Marvel Comics)|Thor}} from the {{w|Marvel universe}}, played by  another  possible thrower, {{w|Chris Hemsworth}} in the {{w|Marvel_Cinematic_Universe}}, and {{w|Mjolnir (comics)|his hammer}}, which is enchanted such that only those deemed "worthy" are able to lift it. As such, despite its mass in principle being liftable by many of the characters, only Thor, God of Thunder (who is canonically worthy), is able to throw it. Also Thor is the only one who uses {{w|furlongs}} to measure his distances among the standard throwers. However, it is not a canonical part of this comic that only he can throw it, and its mass is not realistic, see more below.

[https://www.explainxkcd.com/wiki/images/f/f3/2198_Throw_-_Original_without_you.PNG Originally], when the comic was just released, there where only 7 throwers and 15 things to throw, giving a total of 105 different combinations; see the [[#Table of throw distances|table]] below. But only Thor can throw all 15, with three of the objects (George Washington, Thor's hammer, and the car) unthrowable by any of the other throwers. The smaller critters can throw only a few things, so the total number of throws is much less than 105. Still, there is an animation for all 105 combinations, but with no throw distance for many of these. 

But already on day one the comic was out, a new thrower was added with the standard name "You", and this person, with black hair and a [[1350:_Lorenz#Knit_Cap_Girl|knit cap]], was also added to the objects that can be thrown increasing the number of throwers to 8 and objects to be thrown to 16. However, it would not be true to say that the number of options now would be 8 x 16 = 128, since the "You" can be customized when selecting it in the throwers menu (but not when selecting You in the object menu). When doing so a new window called [https://www.explainxkcd.com/wiki/images/thumb/4/48/2198_Throw_-_Custom_thrower.PNG/835px-2198_Throw_-_Custom_thrower.PNG Costume thrower] will open up over the comic. The "You" option can then be customized by changing the name (from the default "You"), and defining the height (default 5.8 ft = 1.77 m) and weight (default 160 lb = 72.57 kg), where ft (feet) can be changed to m (meter) and lb (pound) can be changed to kg (kilograms). But when doing so the window will not correct the number from feet to meter etc. but stay the same. 

Below the above options there is line with four persons above it, defining a scale of ''athleticism'', the default second option being the drawing of "you" which represents ''Decent'' form (i.e. a normal person).  The first on the scale is [[Black Hat]], who thinks moving things is for suckers, thus representing minimal athleticism. "You" in second position is in decent shape and pretty good form, representing decent athleticism. George Washington in third position represents extremely high athleticism, and as he states he threw so well they made him President. Finally the fourth position, representing a champion athlete, shows a person with a helmet with chin strap and goggles who states that he trains 36 hours a day by using a time machine. It is thus indicated that such athletes can only be so good by training more than is possible; for instance, if he travels 24 hours back every day, he could use 12 more of these to practice, making it 36 hours on that "normal day" and he would then still have 12 hours to eat and sleep/restitution before his next 36 hours training pass.

Changing away from the decent "You" to one of the other three characters on the athleticism scale does not, however, change the character used for the animation, which stays the same. But still this gives a very large number of different "yous" to both throw and be thrown. 

A self-created character, unrealistically tall and heavy well over the human records for height ({{w|List of tallest people|272 cm}}) and/or weight ({{w|List of heaviest people|635 kg}}), can actually be able to [https://www.explainxkcd.com/wiki/images/e/e3/2198_Throw_-_You_throw_hammer_settings.PNG throw Thor's hammer] (For instance 4m and 1000 kg, see more [[2198:_Throw/Screen-shots#Hammer_throw|here]]. So it is not because it is magically inclined to only be thrown by Thor, it is just that the weight is set to 2000 kg, and only Thor of the standard characters have the strength (1000 times normal human strength) to throw such a heavy object. But if the "You" is big enough, the athletic difference with Thor will be compensated by sheer weight and height. See this table of [[2198:_Throw#Data_from_xkcd_code|data from the comic]] for the above numbers.

Interestingly, Thor can throw a squirrel 257 meters.  If a Custom Thrower is created, and they are 200 meters tall and 150 KG, they can throw the squirrel 256 meters (1 meter less than Thor).  Thor can throw an acorn 136 meters, and the Custom Thrower will throw it 133 meters.  Now, Thor can throw Thor's Hammer 19 meters.  The Custom Thrower can throw it 44 meters!  Apparently there is more to the enchantment of Thor's Hammer than meets the eye, as it would have been expected that if Thor can throw a squirrel and an acorn farther than an extraordinary human, then certainly he could throw his own enchanted Hammer a longer distance. This is, of course, because the Custom Thrower now throws from much higher than Thor.  As to why the height doesn't affect the acorn or squirrel throwing distance in the same way it does Thor's Hammer, we'll leave that to you, the reader.

The title text refers to throwing a party (a colloquial synonym of hosting a party) and first makes the assumption of actually giving hints for giving a party, and then switches to suggest a mechanism to literally throw a huge object, such as a house with a party going on inside. An {{w|Aircraft_catapult#Steam_catapult|aircraft steam catapult}} is a mechanism to launch aircraft from ships, typically used on aircraft carriers.

==Safety Considerations==
Many of the items, even if technically possible to throw, may not be able to be thrown safely.  

For example:
* Depending on how the microwave oven is damaged when it hits the ground, it may still be able to appear to function, but no longer seal properly, and therefore leak dangerously high amounts of microwave radiation.
* Blenders have blades and glass.  Even if no one is struck by the flying blender, the broken pieces would be hazardous later if they are not properly disposed of.
* Cars have gasoline and battery acid which may spill if one is thrown.
* A squirrel might bite the person attempting to throw it, which is dangerous as some squirrels have rabies.
* Pikachu could shock (possibly fatally) someone trying to throw it.
* If a {{w|Dwarf-tossing|person is thrown}}, that person may be badly injured. If you throw people without consent they might punch you.

==Throwers and throw items==
*Here is a table with first the throwers and then the objects to be thrown.
**George Washington, Pikachu, and the squirrel are both throwers and throwable objects, as are the costumed option "You".
**For these four this is noted in the explanation. The "You" is also the first object, Washington and Pikachu is no. 11-12 and the Squirrel is also the last object (no. 16) in the object list.

|'''{{w|human|You}}''' 
|'''Can also be thrown'''. The viewer may also choose to create a custom thrower, for instance, themself, inputting a name, height, weight, and general level of athleticism, as measured on a scale from "[[Black Hat]]" to "championship athlete" (a swimmer is pictured). The custom thrower is also selectable as a throwing item, presumably to provide more variety compared to the fixed values of George Washington.
|-
|[[File:2198 Throw - george.png]]
|'''{{w|George Washington}}''' 
|'''Can also be thrown'''. The first president of the United States of America. There is a myth that a young George Washington threw a silver dollar across the Potomac River, which is more than a mile wide for much of its length; or alternatively that he would throw rocks across the Rappahannock River, which was about 300 feet wide near George's boyhood home. http://kenmore.org/education/kidstuff/legends.html. He is also used as a throwing item to represent the likelihood of a thrower distance with an average human as the projectile. George Washington is shown as a very powerful thrower; the comic makes fun of the flagrant embellishment of Washington's life.

|[[File:2198 Throw - quarterback.png]]
|'''An NFL {{w|quarterback}}'''
|A quarterback in the National Football League is a highly athletic individual.  Gridiron football is a full-contact sport that requires durability, speed, and precision. One of the primary skills required of quarterbacks is to be able to throw the football far with precise accuracy.
|-
|[[File:2198 Throw - pikachu.png]]
|'''{{w|Pikachu}}''' 
|'''Can also be thrown'''. Pikachu is a species of Pokémon and the mascot of the Pokémon franchise as a whole. Although Pikachu are not normally shown to throw things, the ''Super Smash Bros'' series shows they are perfectly capable of picking things up that do not significantly out-size them. That said, Pikachu is capable of throwing a wide variety of objects through the move Fling, which allows the user to deal damage by throwing its held item (and, incidentally, a Fling TM). Its presence as a throwing item appears to reference the most recently released Pokémon games as of the comic's release, ''Pokémon Let's Go Pikachu'' and ''Pokémon Let's Go Eevee'', where the partner Pokémon of the respective title is not kept in a Poké Ball but thrown into battle when deployed. <br>According to Pokédex entries throughout the series, the average Pikachu is 1'04" (0.4m) tall and weighs 13.2 lbs (6kg). Randall appears to have done his research, as a custom thrower with these stats and default athleticism will have near-identical results to Pikachu for both thrower and thrown item.

|'''A {{w|squirrel}}'''
|'''Can also be thrown'''. A small mammal of the family ''Sciuradae'', known for hoarding acorns. Squirrels have been a [[:Category:Squirrels|recurring topic]] on xkcd and have been used in ''What if?'' in lieu of a subject that Randall really doesn't want to draw. Due to their small size, a squirrel is also selectable as a throwing item.

|-
|[[File:2198 Throw - pingpong.png]]
|'''A {{w|ping pong ball}}'''
|A small plastic sphere designed to bounce, used as a projectile in the sport of table tennis or "ping pong". Notably the ball is much more difficult to throw than the acorn, as its larger size yet much lighter weight causes it to lose more momentum due to air resistance.
|-
|[[File:2198 Throw - acorn.png]]
|'''An {{w|acorn}}''' 
|A small nut which grows on oak trees and often serves as a squirrel's primary form of nourishment.
|-
|[[File:2198 Throw - hammer.png]]
|'''{{w|Mjolnir (comics)|Thor's hammer}}'''
|Mjolnir, an enchanted hammer in the {{w|Marvel universe}} which belongs to {{w|Thor (Marvel Comics)|Thor from Marvels comics}} and can only be lifted by those deemed worthy.  It is based on {{w|Mjölnir}} the hammer of Norse God {{w|Thor}}, God of Thunder.  In this comic, though, it appears that Mjolnir is just incredibly heavy, and Thor is able to throw it because he is very strong.  The custom thrower is also able to throw it if their size and strength are set high enough.  Setting aside this customization, Thor is the only standard thrower to be able to throw Thor's hammer.  In the movies based on the Marvel universe, Thor is played by Chris Hemsworth, who is also one of the throwers, but in real life, he would of course not be able to throw such a weighty hammer.

|'''A {{w|Dollar coin (United States)|silver dollar}} tumbling'''
|The coin's other possible trajectory, '''tumbling''', as might result from flipping a coin to make a decision. The spinning coin always goes farther than the tumbling one, since facing the air edge-on leads to a smaller area facing the wind and therefore less air resistance.

|-
|{{w|List_of_humorous_units_of_measurement#Wiffle|Wiffles}}
|0.0089
|A Wiffle, also referred to as a WAM for Wiffle (ball) Assisted Measurement, is equal to a sphere 0.089 m (3.5 inches) in diameter – the size of a {{w|Wiffle ball}}, a perforated, light-weight plastic ball frequently used by marine biologists as a size reference in photos to measure corals and other objects. Randall is thus a factor 10 off. While wiffles should be the next unit after rack-units and before feet, the unit conversion typo seems to prevent it from being accessible by any thrower-object combination, as it is now even smaller than the wrong measure for light-nanoseconds. Wiffles have thus only been discovered in the data of the comic, as it seems to be impossible to get it displayed in the comic itself.
|-
|{{w|List of unusual units of measurement#Light-nanosecond|Light-nanoseconds}}
|0.0299
|The light-nanosecond was popularized by Grace Hopper, referring to the length light could travel in a nanosecond. The actual length of a light-nanosecond is 0.299 m, about a foot long, but it seems that [[Randall]] was off by an order of magnitude. This measurement is used for lengths from 1 to 1.06 m, but none of the standard throwers or objects can be thrown for this short a distance, so it is not included in the table above. But with the custom user it is [https://www.explainxkcd.com/wiki/images/a/a5/2198_Throw_-_Light_nanoseconds_1m.PNG possible to get down to 1 m] where it will then be used, but of course, since it says 33 light-nanoseconds instead of 3 it is wrong. See some examples [[2198:_Throw/Screen-shots#Light_nanoseconds_error|here]].
|-
|{{w|List_of_humorous_units_of_measurement#Attoparsec|Attoparsecs}}
|0.03086
|The parsec is a unit of length used to measure large distances to astronomical objects outside the Solar System. A parsec is defined as the distance at which one {{w|astronomical unit}} subtends an angle of one {{w|arcsecond}}. One parsec is equal to about 3.26 light-years or 31 trillion kilometers (31×10<sup>12</sup> km) or 19 trillion miles (19×10<sup>12</sup> mi). Atto- is a unit prefix in the metric system denoting a factor of 10<sup>−18</sup> or 0.000000000000000001. Together the two-unit exponents will almost cancel out, as 31 trillion kilometers can be written as 3.1×10<sup>18</sup>cm, meaning that an attoparsec is 3.1 cm. The unit is only used three times in non-customized settings: once for Pikachu and twice for the squirrel. This measurement is used for lengths from 1.06 to 2.69 meters. See [https://www.explainxkcd.com/wiki/images/7/79/2198_Throw_-_Attoparsecs_107cm_setings.PNG example here].

|{{w|List_of_unusual_units_of_measurement#Rack_unit|Rack units}}
|0.0445
|A {{w|Rack unit}} (abbreviated U or RU) is a unit of measure defined as 1 3⁄4 inches (44.45 mm). Mainly used to measure the overall height of the likes of {{w|19-inch rack}} frames or the equipment put in there. It is used for lengths from 2.69 to 6.67 meters.
|-
|{{w|Foot (unit)|Feet}}
|0.3048
|One foot is defined as 0.3048 meters.  In customary and imperial units, the foot comprises 12 inches and three feet compose a yard. This measurement is used for lengths from 6.67 to 16 meters.
|-
|{{w|List_of_humorous_units_of_measurement#Smoot|Smoots}}
|1.7000
|The {{w|Smoot}} is a nonstandard, humorous unit of length created as part of an MIT fraternity prank. One smoot is equal to {{w|Oliver Smoot}}'s height at the time of the prank, 5 feet 7 inches (1.70 m). Mr. Smoot was used to measure the length of the Harvard Bridge (connecting Boston and Cambridge) by being repeatedly laid down along the length of the bridge; the markings indicating distances in smoots along the bridge have been maintained by the fraternity. This measurement is used for lengths from 16 to 36 meters. While the smoot is a nonstandard unit of length, Oliver Smoot has been chairman of the American National Standards Institute (ANSI) and President of the International Organization for Standardization (ISO).  ANSI and ISO are among the world's main standardizing bodies, so Randall may indirectly be making the pun that while Smoot's body isn't a standard measure, Smoot has been in charge of bodies that standardize measurements.

|2.4
|The length of a {{w|horse}} varies a lot with the horse type, breed, age, and genes. In the Wikipedia article on horses, the length of a horse is not even mentioned, only the height and weight. But Randall has used horses for measurements before. A {{w|horse length}} is approximately 8 feet (2.4 m). This measurement is used for lengths from 36 to 75 meters.
|-
|{{w|List_of_unusual_units_of_measurement#Block|Manhattan blocks}}
|80.0
|The numbered streets in {{w|Manhattan}} run east-west and are generally 60 feet (18 m) wide, with about 200 feet (61 m) between each pair of streets. With each combined street and {{w|City block|block}} adding up to about 260 feet (79 m), there are almost exactly 20 blocks per mile. The typical block in Manhattan is 250 by 600 feet (76 by 183 m). When driving in a grid-like city, the {{w|Manhattan distance}} between two points is a concept, although it is also called {{w|Taxicab geometry}}. It seems like it is indeed the combined street and block distance. This measurement is used for lengths from 75 to 131 meters.

|{{w|List_of_unusual_units_of_measurement#Football_field_(length)|Football fields}}
|91.44/109.728
|A football field in the comic is 100 yards or 91.44 m long. An {{w|American football field}} is 100 yards between the end zone although by including those it is actually 120 yards or 109.728 m. Although it is an American comic, it doesn't state that it is an American Football field. A {{w|Football pitch}} in {{w|Association football}} (Soccer) is also often used, and although the length of those varies the usual size for champions league matches is 105 m. This measurement is used for lengths from 131 to 201 meters.
|-
|{{w|Furlongs}}
|201.168
|A furlong is a measure of distance in imperial units and U.S. customary units equal to one-eighth of a mile. It is part of the {{w|List_of_humorous_units_of_measurement#FFF_units|FFF_units}} of the {{w|FFF system}} for furlong/firkin/fortnight, length, mass and time. One furlong should therefore be 201.168 meters, though the United States does not uniformly use this conversion ratio. Older ratios are in use for surveying purposes in some states. Only Thor's distances are given in furlongs. This measurement is used for lengths of 201 meters (1 furlong) and up. For the standard throwers and items only Thor can throw over 200 m, thus only he uses Furlongs to measure his throws. Given that this is an old unit, and Thor is based on ancient Nordic Mythology, this may seem appropriate.

===Data from xkcd code===
*A user got this data from the code (and added it to the comments).
**But it makes sense to include here:
*From this it can be seen that:
**Thor's Hammer is not special, just very heavy, 2000 kg despite being rather small.
**Thor has the same stats as Chris, except he has 1000 times more Throw power (10,000 vs 10).
*The custumizeable You can have Throw power of 5, 10, 15 and 20, and wight and height can be set along with the name. 
**The diameter is calculated from the formula given, so in the standard setting it is about 0.5 m.

===Formulas===
<math>\begin{array}{lcl}
g&=&9.805 \frac{\mathrm m}{{\mathrm s}^2} = 9.805 \frac{\mathrm N}{\mathrm{kg}}\\
A&=&\sqrt[3]{\frac {3 * \mathrm{thrower\_length} * \mathrm{thrower\_throwPower} * \mathrm{thrower\_mass}} {\mathrm{object\_mass} + \mathrm{thrower\_mass} / 1000}}\\
B&=&\sqrt{\frac{2 * \mathrm{object\_mass} * g}{\pi * {(\mathrm{object\_diameter} / 2)}^2 * 1.2041 \frac{\mathrm{kg}}{{\mathrm m}^3} * \mathrm{object\_dragC}}}\\
\mathrm{distance}&=&\frac{A^2 * \sqrt2} {g * \sqrt{\frac{A^4} { B^4} * 0.8 + \frac{A^2} {B^2} * 3 + 2}}
\end{array} </math>

Constants and Units:
* g is the gravitational acceleration (on earth)
* 1.2041 kg/m³ is the density of air at sea level
* A (in m/s) is the calculated throw speed regardless of direction, if you assume constant throw power over time in Watts and the body length as acceleration distance (arm has half the body length and goes from back to front) from 0 m/s to the final speed 
* B is the possible throw speed, which still does not air brake the object too much. If the object is thrown at that speed, i.e. A = B, the distance is reduced to 58,7%. B is only dependent on the object. If B was set to infinite, the air resistance would be removed from the formulas.
* throwPower is in m²/s³, or equivalently W/kg (Watts per body mass)
* dragC is without unit and signifies the air resistance of the object and is dependent on the shape

==Extra pages==
As this comic is very complicated several screen shots and tables are needed for the full explanation. In order to keep this main page easy to use, these pictures and possibly some of the tables will be placed on some extra pages, as has also been done with [[:Category:Comic subpages|other complex comics]] in the past:
*[[2198: Throw/Screen-shots]]

==Transcript==
:[As this is an interactive comic, not all possible text should be given in this transcript. Also, it is not possible to see all the different throwers or objects in one image. This transcript here includes the text that can be found when loading the page, without changing the thrower or object (the default), but also includes the text that can be found by scrolling in the two select "windows" as that would be similar to a long comic where you need to scroll as well as customization options. For further differences that occur by changing the objects refer to a table of all combinations.]

:[A heading with a subheading is above a line, beneath which are a sentence, that is generated by the selections in the two windows beneath this sentence:]
:<big>'''Throw Calculator'''</big>
:This calculator implements the approximate throwing distance estimation model from ''How To'' Chapter 10: ''How to throw things''.

:How far could George Washington throw a Microwave oven?

:[Beneath this sentence are two "windows" with a frame around them, one to the left and one to the right, each with a heading breaking the top frame. Each also has a scroll bar to the right, which allows one to scroll down through 8 different possible selections in the left window and 16 in the right window. There are, depending on the browser zoom level, one or two selections on each line. Each window's content is given here under their respective headings. Each possible selection is a drawing with a caption beneath it.]
:Select a thrower

:*You
:*An NFL Quarterback
:*George Washington
:*Pikachu
:*Carly Rae Jepsen
:*Thor, God of Thunder
:*Chris Hemsworth
:*A squirrel

:Select an object to be thrown

:[Below the two windows is the result of the animation that will happen when a selection has been made. An animation of the selected thrower throwing (or failing to throw) the selected object is shown, and the object's traveling distance is measured out both in meters (SI units) and in some other unit in brackets below. If the distance is not too long compared to the size of the object and thrower, then both can be seen, and in case the object is soft it may break from the throw.]

:[In the pre-selected version, George Washington throws a microwave oven, which ends up several meters from him lying on a corner broken with its wire lying beneath it. The distance is given under the ruler along which the throw has occurred, with markings for approximately every meter. In this case, there are seven steps even though the distance is above 7 meters:]
:7.76 meters
:(25.46 feet)

:[Clicking on "You" in the thrower box opens a new window over the above described comic parts. some of the comic can still be seen including the thrower and his item, and a new throw occurs every time something is changed in this new window. It is a customization box with several options shown below.]

:Your Name
:____You_____ [can be changed]

:Height
:5.8 ft [number can be changed; ft can be changed to m]

:Mass
:160 lb [number can be changed; lb can be changed to kg]

:Athleticism
:[Below is a scale showing Black Hat, the character depicting You with a knit cap, George Washington, and a person with goggles and a helmet. A marker is set at You, but can be changed. Below the characters are descriptions.]
:Black Hat: Moving objects around is for suckers.
:Minimal
:You: I'm in decent shape and have pretty good form.
:Decent
:George Washington: I'm so good at throwing they made me president.
:Extremely High
:Goggles: I use a time machine to train for 36 hours a day.
:Champion Athlete

:[Once done the box can be clicking on a cross at the top right or just clicking outside the window on the comic behind it. Now the thrower you (and the object you) will have the weight, length and strength chosen and will be able to throw (or be thrown) with these stats. ]

==Trivia==
*The comic refers to Thor as the character from the Marvel comics and movies (and other media), who is himself a reference to the ancient Norse god.  In Marvel Cinematic Universe movies, Thor is played by Chris Hemsworth.
*Thor's hammer, Mjölnir, bears an enchantment that prevents any living being from lifting it unless they are "worthy." This is reflected in the simulation by giving Mjölnir a mass of 2,000 kg.
**In-universe, Thor's hammer weighs [https://urbandud.files.wordpress.com/2011/08/detail-128-thors-hammer.jpg?w=550 42.3 pounds].
*The option to customize your own character was added to the comic later.
*Due to a bug, the calculations for the customized person ('you') are incorrect when the mass is specified in pounds
*When the comic came out there was a mistake so the item to be thrown was named the same as the thrower, except for the coins and for when Pikachu and George Washington tried to throw themselves in which case it for instance said:
**[https://www.explainxkcd.com/wiki/images/9/93/2198_Throw_-_Original_error_George_Himself.PNG How far could George Washington throw himself?]
**But if he picked another object it would write:
***[https://www.explainxkcd.com/wiki/images/c/c9/2198_Throw_-_Original_error_George_George.PNG How far could George Washington throw George Washington?]
**See more examples [[2198:_Throw/Screen-shots#Errors|here]]
===Examples of distances===
*The [https://www.explainxkcd.com/wiki/images/5/5a/2198_Throw_-_You_1_kg_throw_hammer_max_distance.PNG maximum distance] of any throw is 743079 m, which Thor's Hammer can be thrown by a customized you that is high enough. If the height is large enough the mass can be the [https://www.explainxkcd.com/wiki/images/8/8e/2198_Throw_-_You_1_kg_throw_hammer_max_distance_setting.PNG minimum 1 kg]. 
**See details [[2198:_Throw/Screen-shots#Maximum_distance|here]]. 
***However the comic asks the user to not use height over 100 m and mass over 1000 kg. 
***See details [[2198:_Throw/Screen-shots#Maximum_height_and_mass|here]].
*A one foot tall Champion Athlete You with a mass of over 524,644.3 pounds can throw the car 44 feet. In fact, the mass can be defined to 70 or more decimal places, with each incremental change allowing You to throw the car 44 feet, as long as the addition is sufficient
**Tester used trial and error and became bored after inputting the mass below:
***524,664.3134471218218095600605010996328125[35 zeroes]1
*A one pound Champion Athlete You with a height of 480,651 feet, 1 and 9/64th inches can also throw the car 44 feet
**Subtracting 1/64th of an inch prevents the CAY from throwing the car
