Magnetic Torpedoes

These are two very strong magnets. One dramatic trick you can do is as follows. Separate the two magnets in your hand by about 25mm (holding them firmly otherwise they will just lock together) and then throw them in the air together. Initially they will rattle in the air before they join together. The rattling sound is amazing – something like a demented cicada. At one time these were advertised on www.grand-illusions.com.
