That was really common in schools. Not sure what year but folks 50+ probably all had
similar fun with hands on mercury time at school. (I know my folks did).

One needn't actually DRINK the mercury (or even hold it in one's hand) in
order to demonstrate, or even look at, a mercury delay line. I'm willing to
bet that most of those schools have mercury-switch thermostats everywhere.
Every school I attended did.
In high school science class the teacher brought out a jar full of it and poured it out on
the tabletop (it had an edge).
We got to play with it, tried picking it up with our fingers, etc.
No big deal.
Mercury
delay?
That would be cool, but I think schools might have a problem with that these
days. -Dave
