When I was in the service near Chicago in 1969 I visited the Chicago
Museum of Science and Industry and saw a "perpetual motion" machine.
It worked vaguely thus:

A ball bearing dropped out of the end of a tube, fell about 18 inches
onto the slanted top of a solid cylinder which deflected the bearing
left about 3 feet to the top of another cylinder. It then bounced
vertically into the mouth of the tube, rolled slightly downhill and
to the right about 3 feet only to fall back out the end and start it's 
cycle over again. There were maybe 15-20 bearings in the system and
they continually went thru this pattern, each clicking with the following
one at about 1 per second.

It was fascinating to watch and I've always wondered if it was still 
working. Maybe Mr. Burch or someone else in the Chicago area knows or
could find out. It's a good excuse to visit a wonderful place.
