When I was a kid we used to play with mercury. We had about a half cup we would roll around and make it come together like the the bad guy in Terminator 2. We did science experiments in school with mercury too.
It is not as dangerous as it is now made out to be, just don't eat any. Mercury is a heavy metal, and like steel or aluminum metals, does not soak into your skin. Shake it out of your drawer into a trashcan and get on with your life.
