Chemmunity: a collaborative chem project where no suggestion is too dumb

[Wraithcraft]

Urinium: Glowing green goo that smells like piss.

Makes you pee when it's in your system. You'll pee out chems too. It's like a sillier calomel that's just piss.
I stole this chem from a thread somewhere, all credit to whoever came up with this first.
