A question about rule 1

It depends on the chemical. Stuff like cryostylane and liquid black matter IS in fact harmful, cryo will cause a lot of slips over a large area and liquid black matter can insta crit people depending on the amount of stuff nearby.

Go for something gimmicky and truly harmless like fartonium, sakuride etc!

They all say fartonium is harmless until you Throw the bibles under people . Beware the Fartonium!

Oh yeah on topic, yeah Pretty much non lethal things dont really matter. Go ham. You can test explosions on Space diner tho, As long as you make sure nobody is on there before you do it. Its quite common practice for people to test bombs there actually.
