==Explanation==&lt;br /&gt;
{{incomplete|This page was created by THE EXTENSION CORD FROM COMIC #509. I can't explain the anchoring it to the wall part yet, and I didn't do the title text. Don't remove this notice too soon.}} &lt;br /&gt;
&lt;br /&gt;
This comic begins with Cueball approaching Ponytail, who’s sitting at her desk, asking if she has an extension cord with prongs at both ends that he can borrow. To which she replies with a horrified NO!!!  Whether the no means that she doesn’t have the cord, or she does but Cueball can’t borrow it is unclear (though the second panel would suggest it’s the former). This design of extension cord (created to solve some power-connectivity issues, but likely to cause other problems) is lethally dangerous, as Ponytail points out. They are also known as [https://www.consumerreports.org/home-garden/generators/why-suicide-extension-cords-are-so-dangerous-a1189731437/ suicide cords] for this reason.&lt;br /&gt;
&lt;br /&gt;
Ponytail seems to relax when she persuades Cueball to use a regular extension cord instead, which normally wouldn't even be an option where such a double-ended cord was required. But then he elaborates that rather than wanting the cord to carry electricity, he actually intends to use it as some kind of support prop. He thinks that the plug prongs at each end are suitable for fixing the cable into a wall (though he doesn't specify, presumably two regular wall-sockets - depending upon the exact type of plug/prongs he uses, this itself would be a problem, connecting the opposite polarities of the same building supply together), ''this'' leaving the free cable between in the right place to act as a makeshift support for something even more dangerous: plutonium. Based on his description his setup appears to be a recreation of Louis Slotin's infamous &amp;quot;Demon Core&amp;quot; or &amp;quot;Tickling the dragon's tail&amp;quot; experiment, {{w|Slotin#Criticality accident|which proved fatal}}, with the extension cord replacing the flat-head screwdriver. Understandably, this horrifies Ponytail even more. This is the third comic to reference the Demon Core experiment, after [[1242: Scary Names]] and [[2593: Deviled Eggs]].&lt;br /&gt;
&lt;br /&gt;
The title text escalates the innocently mentioned hazards… though arguably not as much as the radioactivity. Loose flour is a well known fire hazard and the key to a {{w|Dust explosion|flour-air explosion}}; 50 bags of it plus some way to get it into the air could blow up a sizable building. Lithium batteries are well known fire hazards when overcharged, which is why the TSA restricts them in checked luggage, and there have been numerous fires caused by the lithium batteries in &amp;quot;hoverboards&amp;quot; leading them to be oft-banned in cities, airports, and by retailers who might otherwise sell them. A bank of 50 might be overkill, but if charged in parallel (serial probably wouldn't work as well), could cause a noticable explosion or fire once one of them hit its limit. And while vinegar and bleach aren't a particular fire hazard, they do release chlorine gas when combined, which is lethal. (''Any'' acid will tend to liberate chlorine from bleach, though vinegar is a relatively dilute solution of a weak acid (acetic acid). Other acidic household cleaning products, such as drain openers, would be much more dangerous to combine with bleach.) As such, the theme of the title text appears to be &amp;quot;innocuous-appearing substances which are actually quite dangerous&amp;quot;.&lt;br /&gt;
