A spectator's bill, which he signs or marks, is placed inside a 9 inches silk with a rubber band. The silk, rubber, and bill are then placed inside a glass. The glass is covered with an aluminum tube. Before you can blink, the bill has jumped from one tube to the other. But even more amazing, the opening of the second glass is now covered with the 9 inches silk which is held on by the rubber band and th is inside the glass under the silk. And, yes, the spectator removes the band and the silk to discover that it is, indeed, his SIGNED Bill.
