Okay they answered the phone. Apparently there is a difference between types of mercury, elemental mercury vs some other kind so she said I'm good.
Phew.
Anyone know how to get mercury out of little tiny concrete cracks? This stuff is super slippery.
Chemists use some sort of vaccum eye-dropper thing to suck up shit like that. Get one of those, or just use the household vacuum. I'm sure that will be fine.
Do you have a dog? Could just pour something he likes on the mercury.
