Psychic Spinning Rings

Take two ordinary metal rings, and make them stick together MAGICALLY - no magnetism is involved! One ring hangs, magically, no magnetism involved, from the other - flick it with your finger and it spins crazily, just as if it is magnetized (but of course it isn't). Go ahead, lay down the rings on the table; let your audience examine them with a keen eye; there's nothing special about them; the specialness, of course, belongs to you, the psychic magician.
