Video Showing A Homopolar Motor Made Of Household Items

Simple Motor Video TrickThis video shows how to make a homopolar motor out of a few household items. You take a battery, a screw, a magnet, and a piece of wire. The magnet goes on the top of the screw and the point of the screw it touching the positive side of the battery. The wire goes from the negative side of the battery to the magnet. This creates a current and causes the screw plus magnet to spin around. Pretty cool little trick the only someone hard to find item would probably be that magnet. It looks like a watch battery but most magnets I've seen are that dull black color.
