holding human organs and mercury in our bare child hands

We did the mercury thing when I was in 4th grade so that was in 1972. But, it was NOT from the teacher giving it to us. I (white kid) was bussed to an all black school because it was the first year of integrated school in the community I lived in. This school was SO poor so, thank God for civil rights and integrated schools because slowly but surely, they got better schoolbooks, furniture, etc. But that first year, wow. We kids were exploring the "old gym" which was barely standing. And it was really just a half court gym- and it was full of old crap-old text books, clothes, sports gear, etc. and we found an old bookcase with jars and I later realized it was from a science classroom. We took the half gallon jar with liquid mercury and it looked really pretty. The biggest kid opened the jar and gave us all some in our hand. Took it back inside with us when the bell rang because it was so cool to play with. It would separate into little balls and you titled you hand and they would group back together into one large one. And not round like a beach ball....Anyway, kid beside me has his in the pencil groove on his desk. So that is where I put mine. The teacher was walking around handing out graded tests and almost died on the spot when she realized what we were playing with. Nobody called our parents, I have no idea if we went and washed our hands..I don't remember anything except the teacher freaking out and making us put it in the trashcan. I've made it to 62 with no serious ailments so...law of averages-it could go completely sideways-but I am hoping I stay well.
