I broke a mercury thermometer in my bedroom. It was inside it's closed protective case, but when I picked it up, it opened and thermometer slipped on the floor. Made in Germany btw (German quality my ass). I manage to collect about 99% of spilled mercury, but even 1% is enough to poison 10 homes like mine. Moral of the story - if you have a mercury thermometer, get rid of it now. It's like keeping a loaded gun, one day it WILL fuck you up.
