SuperMagnetMan (love the name) demonstrates in this video. The power of magnetism causes chunks of metal to take flight. The victims in the video: a ketchup packet, a lime and some grapes. The real danger, though, can be found on the Sciencepunk blog, which has all the evidence you might need, including an x-ray and a bloody photo, to convince you to be careful with these things.
