Physico-chemical properties
It is a non-flammable, colourless liquid in atmospheric conditions. The compound is very volatile and its smell has been described as "usually ethereal".
gollark: It's apparently big enough that you would need something like 20 high-end compute GPUs, so... quite a lot of raspberry pis.
gollark: The trouble with this is that scaling it up like this requires ridiculous amounts of computing resources, and now it's so big that individuals probably can't even tractably run it.
gollark: It can add somewhat larger numbers!

gollark: Apparently there's a GPT-3 now, and it's basically just a bigger GPT-2 which is somewhat more effective.
