I've got to ask you sth. Is it acceptable and safe to show mercury to students in a primary/secondary school? I mean give Hg in glass (petrie dish or test tube) to their hands.

Is elemental mercury really as dangerous as people make it out to be?
I mean as long as I'm not eating it or snorting it, the vapor pressure is less than water, am I really going to come out with parkinsons if I roll it in my hand for a few minutes?
