Some years ago, the head of the chemistry department at Carleton U began his "Magic with Chemistry" show by sprinkling damp NI₃ on the auditorium steps farthest from the front of the hall. Anyone who tried to come in quietly after he'd started got the snap-crackle-pop underfoot and the embarrassing attention of everyone in the room. In retrospect, it was a rather dangerous stunt... but he did tend to live dangerously.

I played with model rocketry when I was young, but just using commercial solid-fuel engines. I've still got most of my equipment and I'd like to try using it again. I probably should be very very careful with those old engines.
