Chemistrybros needed. /k/ here, but that's irrelevant
HYPOTHETICALLY, how would one go about *SAFELY* creating a solid, toxic chemical compound that disperses from a metal canister in a gaseous form when activated, akin to the filler inside an M18 smoke grenade? Kinda like making Chloramine gas with bleach and ammonia, but in solid form.
I'm not actually gonna do it, but I wondered what the most efficient "recipe" would be if I were to hypothetically make one.
