Some fun stuff there.

Maybe someone can help me. I've been looking for a perpetual motion device that doesn't use magnets or batteries, that once you set it in motion, it keeps moving on it's own kinetic energy. The web site tommy sent us to has one, but it uses a battery, so it's not really a perpetual motion device. I've googled them and can't seem to find anything of suitable quality or interest.

Not trying to derail the thread tommy, some of the stuff on that site is just plain fun. Thanks for posting it.

The Levitron, when put into a vacuum, seems like perpetual motion. It will spin for many hours.

Thanks Iven, but my requirements are no batteries or magnets. Still, it looks like fun. :)
