Every year during my lab safety lecture, I have the kids turn on the eye wash and pull the safety shower chain with a bucket under the shower head. This year, on about the fourth or fifth kid, the valve got stuck in the “on” position, and dumped about 10 gallons of water on the floor before we finally got it to shut off. (I was the one holding the bucket at the time, which resulted in my getting rather soaked.) I managed to maintain my composure, though I was a little flustered and extremely nonplussed…
The custodians gave me a good-natured and extremely well-deserved hard time about it. :-}
