==Explanation==
{{incomplete|Created by a HIGH BOT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This comic starts out with three effects of high altitude related to the air getting "thinner" and the lower air pressure. {{w|Denver}} is one mile (5280 feet or 1609 meters) above sea-level (as marked on the steps of the State Capitol). At this elevation, the [http://www.altitude.org/air_pressure.php average atmospheric pressure] is about 83% of sea level pressure, or about 840 mbar instead of 1013 mbar, and [https://www.sensorsone.com/local-gravity-calculator/ gravity] is 99.94% of gravity at sea level at the same latitude, or 9.796 m/s<sup>2</sup> instead of 9.801 m/s<sup>2</sup>. This has a number of effects:

* Water {{w|boiling|boils}} at 202 degrees F (94 degrees C), slightly lower than the baseline 212 degrees F (100 degrees C) it takes at sea level.
* Baseballs and golf balls fly slightly farther (with the same initial velocity, the distance is inversely proportional to gravitational acceleration so it would be 0.06% farther; in addition, the lower air pressure will reduce the resistance from the air the ball will experience, therefore it will slow down at a lower rate and thus fly even farther than the 0.06% due to gravity).
* {{w|Sunburn}} develops faster because there is less atmosphere above to filter out harmful ultraviolet rays.

As usual for xkcd, the effects of high altitude are extended in a comically absurd manner, applying this "slightly less" rule to things that have nothing to do with altitude:

* {{w|Scrabble}} is a board game where each letter is assigned a point value based on its frequency of use in the edition's language. The comic claims all letters are worth 16% more. When applied to the {{w|Scrabble_letter_distributions#English|normal values for the Scrabble tiles in English}}
** Q is worth 12 instead of 10
** X is worth 9 instead of 8
** Y is worth 5 instead of 4
: This point increase would have little impact in the board game when two players sit across each other. However, it would imply that scrabble played via internet should require players to state their altitude at the beginning of the online game which then assigns advantages to higher-altitude players. This advantage seems arbitrary, unless the altitude difference is really significant enough to impede the thinking ability of the higher-altitude party.
* A common {{w|superstition}} states that breaking a mirror causes 7 years of bad luck. The comic claims that at higher altitudes, only 5&frac12; years are caused. This implies that people living at higher altitudes have less bad luck.
* Marketing campaigns will often state "X is the new Y" to draw the audience of Y in toward the newer X. When used with age, usually at 10 year intervals ("40 is the new 30" is the slogan referenced), it is an attempt to convince an older audience that they can share in an experience commonly associated with a younger audience. At higher elevations, the comic claims, people can use or do things designated for an even younger audience. This is contrary to facts however: Most activities, especially in sports, are more difficult at higher altitudes, not easier.
** In the base 16 ({{w|Hexadecimal|hexadecimal}}) number system, the value 28 represents 2 * 16^1 + 8 * 16^0 = 40. Thus, 40 is the new 28. Likewise, in the base 8 ({{w|Octal|octal}}) number system, 50 represents 5 * 8^1 = 40. Remember that, although {{w| Answer to the Ultimate Question of Life, the Universe, and Everything|Douglas Adams doesn't write jokes about other bases}}, Randall [[1000: 1000 Comics|does]].
* German band {{w|Nena (band)|Nena}}'s hit ''99 Red Balloons'' (an English adaptation of the original song called ''{{w|99 Luftballons}}'') is a song about a war started by a large clump of balloons mistaken for enemy aircraft (see [[#Trivia|Trivia]]). The comic claims that if launched from a higher altitude, 94 balloons would have sufficed.
* {{w|420 (cannabis culture)|4:20}} is a code word for {{w|cannabis}} and has evolved in some circles to be the socially acceptable hour to consume cannabis. This has in turn evolved into a joke that when checking the time and finding it is exactly 4:20, people will add "blaze it" as a reference. The comic claims that, at higher altitudes, the socially acceptable time is earlier, so if there is an elevation of one mile, the socially acceptable time would be 4:17 and therefore, marijuana jokes are made earlier. This joke is probably related to the {{w|Cannabis in Colorado|legalization of recreational marijuana use in Colorado}}.

In the title text, ''{{w|One Hundred and One Dalmatians (franchise)|One Hundred and One Dalmatians}}'' is a Disney franchise (based on a children's book), where the villain, {{w|Cruella de Vil}}, aims to capture and kill 99 Dalmatian puppies (97 in the book) to have the perfect spotted fur coat. (The title includes the parents [book: and other Dalmatian caregivers] of the Dalmatian puppies.) The comic claims that, at a higher altitude in {{w|Flagstaff, Arizona|Flagstaff}} (6903 ft / 2104 m), she would only have needed 89 Dalmatians, possibly implying that puppies at higher altitudes are bigger (perhaps because there is {{w|Decompression (altitude)|less air pressure to compress them}}) and/or that Cruella de Vil at high altitudes is smaller (possibly because of the {{w|Wrinkle#Water-immersion wrinkling|higher humidity and lower temperature}}).

:Megan: 50 is the new 40, and when you account for elevation it's more like 37.

:[Five black balloons floating]
:Nuclear war can be started with only 94 red balloons.

:[Cueball and Ponytail are talking. Ponytail is looking at her phone]
:People make marijuana jokes slightly earlier
:Cueball: Hey, what time is it?
:Ponytail: 4:17 Blaze it!

==Trivia==
*A similar effect on sports caused by different latitudes was the topic of [[852: Local g]]. 
* ''99 Red Balloons'' in the original German lyrics is about one of the nations mistaking the balloons for UFOs from space, and sending a fighter squadron to check. The fighter pilots fire at the balloons, which a rival nation thinks is signs of an attack. This then escalates to a 99 year war. It is generally assumed this war ends in a nuclear exchange, though neither the German nor the English lyrics include reference to the use of nuclear weapons.
