That reminds me of *my* freshman physics class. One lecture, the prof
had the bowling ball pendulum set up in Weniger 151. The ceiling is
about 30 feet tall. He gave the ball a good push and went on to calmly
lecture for a while about pendulums. He turned his back to write on the
bulletin board, and the entire class was treated to the sight of the
bowling ball returning and smashing the overhead projector off of the table
it was on. It seems that the push wasn't quite straight, and the ball
had been slowly oscillating in a wide ellipse, with the projector in the
path of the eighth or ninth cycle.
Needless to say, he was quite surprised... :^)
