Howtoons motor keeps on spinning

This morning I spent ten minutes making the motor from the Howtoons cartoon in the first issue of Make. It consists of one AA battery, two safety pins, a magnet, some Scotch tape, a piece of telephone extension cable wire, a pad of Post-It notes, and a little nail polish. It’s been spinning for four hours so far. I like the clickety clickety sound is makes. I shot a little movie of it in action. (It’s an MP4, so you might have to download it to watch it.) Link
