Best : Have a look at this spinning top toy called, 'Top secret'. I recently ordered one, and received it in the mail today : : http://fog.ccsf.cc.ca.us/~tbardin/html/top_secret.html : While it's not a true perpetual motion machine, it's very interesting, just the same, and it gives the illusion of perpetual motion. My top spun for over an hour today, before I stopped it, but some have apparently spun for days.
