Wa-ay off topic, but this reminds me of an "A"-level chemistry practical
(I guess that's high school equivalent - 16 - 18 y.o.). Take glycerol,
reflux with Mg carbonate (I think). After about 15 minutes, I was the
first to get a yield. Cautious sniff, WHOOF! Staggered back against the
bench. Next lad got a yield, he was on the floor. "lachrymator"? Yeah,
and the rest. Can't remember the LD50 but something fairly scary.
Chemistry is bad for your health.
