This reminds me of a text file I found back in the 1990s on a BBS about “how to build your own atomic bomb”. The first step was something along the lines of “obtain 50 lbs of weapons grade plutonium” as if you could just walk into your local military surplus store and pick up a crate. It was pretty obvious at that point that the whole thing was meant to be humorous.

Monty Python's "Today on how to do it" sketch is the classic of the genre maybe? Definitely a worthwhile minute out of your day.

Another one from that era was something like: "how to destroy the Earth". There were several methods proposed, one of which was to use a black hole: "step1: take a reasonably sized black hole, step2..." etc.

https://qntm.org/destroy might be what you're thinking of? Lots of other good fiction there too. I love the There Is No Antimemetics Division stuff.

Thanks so much!
