| − | In this comic, we see [[Beret Guy]] walking in from the left, as [[Cueball]] is sitting on a couch, typing on a {{w|laptop}} on his {{w|lap}}, with its {{w|power cord}} unplugged. Instead of connecting it to the {{w|wall socket}}, Beret Guy picks it up and blows air into the loose end of the cord, as if inflating a balloon — and the laptop inflates, along with the "power brick" that is on the cord. It then floats away, making Cueball grab for it as Beret Guy casually walks away. (See an instance where Cueball inflates something in a similar unexpected way in [[1798: Box Plot]]).

| − | It is not possible to inflate a laptop like this{{Citation needed}}, and (with [https://www.youtube.com/watch?v=ugVRY-Cv7Ng&t=401s rare exceptions]) it is not possible to inflate ''anything'' by blowing down a power cord. Beret Guy has previously demonstrated several [[:Category:Strange powers of Beret Guy|supernatural abilities]], for instance with power cords, such as in [[1293: Job Interview]].

| − | In general, human breath should not be buoyant enough to lift much in an atmosphere of ordinary air. The only chemical difference between dry air and dry exhaled breath is the conversion of oxygen (molecular weight = 32) to carbon dioxide (MW=44), not counting substances in such low concentrations that their effect on the average molecular weight of the air (MW=29) is negligible. A change of concentration of the CO<sub>2</sub> from [https://www.engineeringtoolbox.com/air-composition-d_212.html 0.04%] to about [https://en.wikipedia.org/wiki/Breathing#Composition 4%] is typical. This increases the average molecular weight. However, exhaled breath is also usually much more humid than air, increasing the concentration of water (MW=18) from a typical value of 1% to approximately 5%, which decreases the average molecular weight. The two changes approximately cancel each other. | + | In this comic, we see [[Beret Guy]] walking in from the left, as [[Cueball]] is sitting on a couch, typing on a laptop on his lap, with its power cord unplugged.

| + | While it is not possible to inflate a laptop like this, nor to inflate ''anything'' by blowing down a power cord, Beret Guy has previously demonstrated supernatural abilities with power cords, such as in [[1293: Job Interview]]. Although the laptop should not actually float given that Beret Guy's breath should be ordinary air, not a lighter-than-air gas such as helium, it is a standard cartoon convention that [http://tvtropes.org/pmwiki/pmwiki.php/Main/AllBalloonsHaveHelium inflating something with breath] nonetheless makes it lighter than air. |

| − | Because humans are warm-blooded, human breath is slightly warmer than the surrounding air, and therefore has slightly fewer molecules per unit volume. This is also true of hot air balloons, but they operate at much higher temperatures than human breath and are therefore able to obtain a greater amount of net buoyancy. There is a standard cartoon convention that {{tvtropes|AllBalloonsHaveHelium| inflating something with breath}} nonetheless makes it lighter than air. Also, given Beret Guy's many manifestations of inexplicable phenomena, it is not too far fetched to believe his body is, in fact, expelling some form of lighter-than-air gas, similar to the character Rigel on Farscape who could "fart helium".
| + | The title text involves some jokes on {{w|Unix}} systems. On Unix, {{w|everything is a file}}, even most of the hardware can be referenced by a (virtual) file. These virtual files usually are in /dev or another virtual filesystem like /sys or /proc. While /dev/input really exists and points to the input system (mice, keyboards, gamepads, etc), /dev/inside doesn't. {{w|gzip}} is a common tool to compress files. The first joke is to compress the air inside the laptop (with the command <code>gzip /dev/inside</code>) in order to deflate the laptop back to normal size. It is a pun with the literal meaning of "deflate", which is also the {{w|DEFLATE}} algorithm used by gzip (uncompressing gzipped files is also called "deflating (the archive)"). Another joke is “{{w|Pipeline (Unix)|piping}}”, the act of using the output of one operation as the input to another. As the output of the gzip command would be compressed air, a ''physical'' pipe could be used to direct the air somewhere useful. The suggestion is to direct the air to /dev/input (in this case, the keyboard) to clean it, similar to "compressed air" dusting cans. As this might cause a spray of unpleasant detritus (compare [[237: Keyboards are Disgusting]]), the reader is advised to avert their eyes. |
