Mad Mags

Description

Effect: Performer shows two ordinary bar magnets. They are red on one end and black on the other. The bars behave just like a pair of bar magnets should, that is, until the magician makes a magic pass. Then the bars go crazy. First the opposite colors attract. Then the like colors attract. Then the opposite colors repel. The bars defy all the laws of physics until the magician makes another magic pass and everything is back to normal.
