I can't work out what Modem mode is meant to do... on my machine it just freezes the whole page. [[Special:Contributions/78.213.151.110|78.213.151.110]] 20:22, 1 April 2026 (UTC)
:It plays the sound of an old-style phone modem, and scrolls the comic into view slowly. It's supposed to represent the early days when downloading an image would take a long time. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 20:31, 1 April 2026 (UTC)
:can confirm on android firefox it seems to render the page unresponsive to input - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 21:18, 1 April 2026 (UTC)
:Same here on Desktop Firefox - under "Modem mode", the whole page freezes up and the browser prompts me to close it ("this page is slowing down Firefox", or words to that effect). I wonder if it's a Firefox thing - odd if so, because I imagine Randall of all people would test on browsers other than Chrom* - or some weird side-effect of my ad/popup/script/cookie-blockers. A shame because all the other modes seem to work - "Greyscale mode" is far too subtle, and I'm ashamed to admit I missed the change from "math" to "maths"! - but this is a great April Fools' comic.

I clicked darker mode and my screen is black and I cant undo it help
:I assume you mean Darkest Mode, since there's no darker mode. The screen turns black but if you look carefully you can still see the grey of the menu and you can click on it. Also, the menu border continues to appear after you select the choice (at least it does on my Mac). P.S. Don't forget to sign your comment with 4 ~ characters.

I read “Modern mode” instead of Modem mode and I spent a while making wild theories about what it could be referencing. But I’m also quite sleepy. [[Special:Contributions/146.70.116.107|146.70.116.107]] 20:51, 1 April 2026 (UTC)

I deminified the code if anyone wants it. There are no hidden options or anything like right-click has, but it would be extremely easy to add modes to it. [[Special:Contributions/2601:441:4B7E:7660:0:0:0:AC72|2601:441:4B7E:7660:0:0:0:AC72]] 20:59, 1 April 2026 (UTC)

applies across the whole website? i forsee a preservation effort in the near future to capture What This Was Like, when randall inevitably removes the menu and all its modes--there's no chance this is staying, is there? - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 21:24, 1 April 2026 (UTC)

:: I know it's april the 1st, but could we keep the modes? Stainglass is fun when the background doesn't turn maroon (and makes the text hard to read). I also checked other pages of xkcd, the modes are on on the other comics.
::Of course it's the April Fools'/Fools' comic. Nice to see it being on time, this year, and I too wonder how long it'll stay. Might it permanently stay on this comic page, perhaps even stay if you jump off of it, but comic 3228 (or the 'default' latest-comic page) will probably be back to normal on Friday.

Dorian Greyscale Mode seems like it ought to use only the white keys on a standard piano, and go DEGFCDBA, with adjacent notes differing in a single bit position. [[Special:Contributions/2A02:8084:2862:4F80:65B7:327D:E614:342F|2A02:8084:2862:4F80:65B7:327D:E614:342F]] 22:56, 1 April 2026 (UTC)

If you're otherwise creating fire hazards, a lithium ion battery is a terrible thing to have, and none of the horror stories you've heard involved a sack of them. Flour is a serious explosion hazard. Vinegar and bleach will release chlorine gas when combined. It sounds like an attempt to have the highest ratio of destruction to materials cost with the least effort.

Would someone mind explaining how the suicide cord can kill grid workers? I don't know if this is easier to understand in the US - we work on a ring main system in the UK, and (once it is plugged in and the prongs thus protected) I'm having problems seeing why it would be a problem even to the end-user (I suppose you could theoretically use it to connect a ring main rated for less current and set the walls on fire?)

:The problem is if you don't plug one end in --[[User:Darth Vader|Darth Vader]] ([[User talk:Darth Vader|talk]]) 10:52, 24 January 2026 (UTC)

EDIT: Gemini reminded me that these are generally used to connect a generator, to power up internal wiring that is depowered - if the grid worker has done this deliberately to work upstream and you power things back up things get ugly.

Electrician here, Suicide cords are used to 'backfeed' a circuit. Homeowners make them when they are too cheap to add a generator outlet. When plugged in, one side has exposed live parts which can shock or kill you. The other danger is backfeeding the grid itself when plugging in a generator (hence lineworker danger) for the exact reason that line interactive inverters for solar arrays need to shut down when the grid is off. Line workers are expecting dead lines when they come down and backfeeding them may make them live on the ground or while the worker is holding them. The proper way to power a house is to have a generator outlet installed and an interlocked panel that disconnects the mains power from your panel (isolating the power lines) and connects the generator power to specific circuits you want.

I added a "Trivia" note that two days before this comic was posted, Randall had put up a YouTube video version of the ''What If?'' item about what would happen if someone's DNA all disappeared. It was compared to the effects of receiving a massive dose of ionizing radiation. The connection between this comic and Slotin's accident seemed relevant to me, at least enough for a "Trivia" item, but another editor disagreed and removed it. Opinions?

I've noticed that recently, these explanations start off very short and without the same humor that most explainxkcd explanations have, and almost appear to be written by AI, before being replaced by a longer explanation that seems more in the vein of this website. Could someone explain what's happening here, and if AI is being used? [[User:CreatorOfWorlds|CreatorOfWorlds]] ([[User talk:CreatorOfWorlds|talk]]) 15:32, 24 January 2026 (UTC)

Regarding "50 lithium batteries": the comic doesn't specify 50, but a pun has slyly been inserted here: {{w|Voltaic pile}} (there are other, somewhat relevant, types of piles as well!) So a "pile" may weigh in less than 50. But there are myriad dangers with lithium-ion batteries. They have many failure modes. So it may not be helpful to focus in on just one of them. I mean, clearly some kind of mischief is going to be wrought, but we really don't know what shape it will take without a list of accessories that are directly related to the "pile of batteries". [[User:Elizium23|Elizium23]] ([[User talk:Elizium23|talk]]) 14:32, 25 January 2026 (UTC)

The correct way to use multiple power sources in case of emergency would be through an appropriate design such as the use of a multi-input UPS with an acid-lead battery for a buffer. This approach could possibly entail the use of "double-pronged" cords in an ill-designed home-made setup. {{unsigned ip|2001:861:3f07:a020:c61f:2d42:ade8:f326|23:24, 25 January 2026}}
:Dear IPv6, welcome to explainXkcd, and please sign your posts with four tildes. Anyway, I am not sure how your comment is relevant to this comic. There is absolutely no "emergency" portrayed here. It seems Cueball isn't in a big rush to get that equipment he wants. Nor is he really preparing to react to an emergency situation. Rather, he seems intent on doing an experiment that will create one, instead. As for batteries and a "multi-input UPS" I suppose that is a fine idea for power outages. Certainly, a "double-pronged AC cord" could be used to "backfeed" the electricity into a home's circuits. But again, I do not see the relevance of your proposed setup to this comic. The title text describes a pile of lithium-ion batteries because it's clearly aimed at creating a disaster by causing them to explode or catch fire in some way. Nobody's getting ready to survive an extended power outage. [[User:Elizium23|Elizium23]] ([[User talk:Elizium23|talk]]) 23:41, 25 January 2026 (UTC)i
::dear Eelizstuffandother, I understand your snide and I do apologize for not signing my post. "suicide cords" are the way to feed 'leccy down an electrical circuitry. If fed through a properly-configured UPS, the problem disappears. Such setups usually make use of lead-acid batteries to buffer the load, as the tech is well-proven, reliable, and less prone to unexpected emergencies. For the record my private personal networw relies on 2 lead-acid UPS and while my oven and other appliances have sufferered from power interruptions several times in the past year, my private network never fell.

Cueball isn't planning to support plutonium with the extension cord; the extension cord would hold up a beryllium half-sphere that goes over the plutonium core and reflects just enough neutrons back into it that, along with the similar reflector underneath, the core starts a chain reaction. (At least, it he's recreating the 1946 experiment.) [[Special:Contributions/2A02:8084:2862:4F80:65B7:327D:E614:342F|2A02:8084:2862:4F80:65B7:327D:E614:342F]] 01:59, 26 January 2026 (UTC)
