A chemistry lecturer I know used to wander around the hall whilst mixing up black powder in a mortar and pestle. Cue nervous students trying not to be near him.

One of my teachers many years ago recalled how he "cured" a student of being over inquisitive and always fiddling with stuff. He deliberately left a pestle and mortar on a side bench with something unstable in it. Needless to say, when the over inquisitive student came in for the next lesson, he couldn't resist giving it a bit of a grind ...

Mind you, we found that most of the cupboards in our form room (a physics lab) weren't locked - oh what fun we had with the Wimshurst machine. Could get some real sparks off that one ! Then one day someone said "what happens if you put a polo mint between the balls ?", so we tried it - put a polo mint in the gap, held by the balls which were adjusted to grip it and wound it up. There was the usual crack as it sparked - and we could find no trace of polo mint, no bits, no dust, we had no idea what happened to it.
