The Floating Paper Cup

Show your audience an opaque paper cup in your left hand. Under your left thumb, in back of the cup, is a small magnet.

With your right hand, lower a steel table knife into the cup. The magnet will cling to it, through the paper, allowing the cup to remain magically suspended in the air as you remove your left hand.

Finish by holding the cup with your left hand cupped over the bottom. As you remove the knife, the magnet drops into your left hand. Pocket the magnet as you hand the knife and cup out for examination.
