==Explanation==&lt;br /&gt;
{{incomplete|Created by a SIPHONIC WINDS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
Cueball and Megan have a demonstration of a {{w|siphon}}, by which the gravitational force on an upper reservoir of liquid and molecular cohesion move a liquid upward through a tube, traversing a higher peak to reach a lower exit.  Randall has also mentioned siphons in his book, &amp;quot;how to,&amp;quot; section &amp;quot;how to make a pool.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Siphons are commonly used in modern society (e.g., most American residential toilets are flushed by siphon action).&lt;br /&gt;
&lt;br /&gt;
Siphons are separate from a similarly counterintuitive phenomenon of {{w|capillary action}}, where a liquid flows through narrow spaces, usually upwards (against gravity) in that a siphon can be of much larger diameter and capillary action can move liquid up an initially empty channel.&lt;br /&gt;
&lt;br /&gt;
Apparently, even though Cueball and Megan have probably set up the experiment correctly, the water no longer demonstrates a siphon by flowing from the upper bucket to the lower. Cueball observes in surprise that &amp;quot;it's true,&amp;quot; meaning that this is a very recent development, and Megan remarks that it was honestly weird in retrospect that scientists had ever tried to rationalise this admittedly counterintuitive phenomenon in the first place.&lt;br /&gt;
&lt;br /&gt;
The punchline of the comic is in the caption, which delivers a piece of physics news that the &amp;quot;2023 update to the universe&amp;quot; finally fixed this phenomenon, dubbed &amp;quot;the siphon bug&amp;quot;. The joke here is that the entire complex and multifaceted system of {{w|physics}} in and of itself is treated as though it's simply the logic (or perhaps the sometimes unintentional result of various default [[1620: Christmas Settings|configuration options]] combined) to a video game, and that siphoning (rather than being an interesting physical phenomenon worth studying) was nothing more than a bug unintentionally created by the &amp;quot;devs&amp;quot; (whoever that may be). In reality, siphons still very much exist in our universe,{{citation needed}} though {{w|simulation hypothesis|the idea that we live in a computer simulation}} is also prevalent in {{w|the matrix|our modern pop culture}}.&lt;br /&gt;
&lt;br /&gt;
The title text is a reference to [[2115: Plutonium]]. It expands on the joke surrounding the idea of an &amp;quot;Earth dev log&amp;quot; by referencing {{w|nuclear power}}, and how it's apparently another bug that some nuclear elements (notably {{w|uranium}} and {{w|plutonium}}, among others) can be and have been harnessed by humanity in order to generate practically everlasting amounts of energy, all while the elements themselves are simply sitting there in the core of some {{w|nuclear reactor}}.&lt;br /&gt;

==Transcript==&lt;br /&gt;
{{incomplete transcript|Do NOT delete this tag too soon.}}&lt;br /&gt;
:[There are two jugs, the one on the left is on a stool and is filled with water, the other on the right is on the ground and has a small amount of water. Cueball standing on the left is holding a tube between the jugs, no water is flowing through it. Megan standing on the right is watching.]&lt;br /&gt;
:Cueball: Wow, it's true—the water doesn't flow up the tube anymore.&lt;br /&gt;
:Megan: Honestly, it's weird that it ever did.&lt;br /&gt;
:Megan: Why did we think that was normal?&lt;br /&gt;
&lt;br /&gt;

When I added the transcript it broke the &amp;quot;Created by a BOT&amp;quot; tag on explanation, even though I didn't touch explanation [[Special:Contributions/172.71.151.98|172.71.151.98]] 05:30, 18 April 2023 (UTC)&lt;br /&gt;
:No, it was broken before your edit.  Someone else changed &amp;quot;BOT&amp;quot; to &amp;quot;Z=90s KID&amp;quot;.  The equal sign causes problems for mediawiki, but it's been fixed now.  --[[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 06:03, 18 April 2023 (UTC)&lt;br /&gt;
::For anyone who would benefit from a deeper explanation:&amp;lt;br&amp;gt;&lt;br /&gt;
::In the syntax for templates, equals signs come after parameter names (see [[mw:Help:Templates#Parameters|Help:Templates &amp;amp;sect; Parameters]]). So, &amp;lt;code&amp;gt;Created by a Z&amp;lt;/code&amp;gt; was parsed as the name of a nonexistent template parameter, and &amp;lt;code&amp;gt;90s KID - Please change this comment when editing this page. Do NOT delete this tag too soon.&amp;lt;/code&amp;gt; was passed in as that parameter's value.&amp;lt;br&amp;gt;&lt;br /&gt;
::That still wouldn't necessarily be a problem. It just also left the first parameter empty. This specific template is programmed to show an error message when that happens. &amp;lt;span style=&amp;quot;background:#0064de;font-size:12px;padding:4px 12px;border-radius:8px;&amp;quot;&amp;gt;[[User talk:AgentMuffin|&amp;lt;span style=&amp;quot;color:#f0faff;&amp;quot;&amp;gt;~AgentMuffin&amp;lt;/span&amp;gt;]]&amp;lt;/span&amp;gt; 06:13, 18 April 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
Two times the red tint around Megan has been mentioned, in explanation and transcript... I cannot see that, no matter how much I zoon in. Is it actually there (can it be measured on the image file?) or is it just someone who wished it was like that? If it can be measrued it should be explained and if not then the mention should be deleted --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:13, 18 April 2023 (UTC)&lt;br /&gt;
:What I meant was that Megan's line art in this comic appeared more brownish/reddish to me than the line art of the other characters. Specifically, the colour hex #472425 using an online colour hex checker. --[[User:Multiuniverse|Multiuniverse]] ([[User talk:Multiuniverse|talk]]) 07:22, 18 April 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
:It's definitely there, but I didn't notice it until I saw it mentioned. It's subtle enough that I imagine certain displays or differences in individual color perception could make it harder to see, but trust me, it's certainly there. [[Special:Contributions/162.158.222.5|162.158.222.5]] 07:24, 18 April 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
::Why is everyone so unsure? it's definitely there. [[User:Mushrooms|Mushrooms]] ([[User talk:Mushrooms|talk]]) 09:00, 18 April 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
:::Not all monitors have the same quality, I can imagine that on some cheapish laptop screens it can be a lot harder to see -- [[Special:Contributions/172.71.131.134|172.71.131.134]] 12:20, 18 April 2023 (UTC)&lt;br /&gt;

Before anyone embarrasses themself by asking, &amp;quot;multimanteau&amp;quot; is obviously a portmanteau of &amp;quot;multiple&amp;quot; and &amp;quot;portmanteau&amp;quot;. Sheesh, get with the neurolinguistic program. &amp;quot;Phrasemanteau&amp;quot; would also be an acceptable neologism. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 11:48, 18 April 2023 (UTC)&lt;/div&gt;</summary>
