HOW TO – Make a screw levitate

Here’s a neat way to levitate a screw with stuff you likely have around the house (besides the magnets) – I’m a little unsure about this one, but will look in to it— “The Levitating Screw is a great trick to do at parties. All you need are two (fairly strong) magnets, a screw, a lime, a coil of copper wire, and a cup of salt water. By arranging these components correctly, you can make the screw levitate several inches in the air, spinning wildly, for several seconds.” [via] – Link.
