A spectators bill is signed and wrapped inside a silk and placed in a glass. The glass is covered with a metal tube. A second glass is placed upside down inside a second metal tube. In the blink of an eye the signed bill jumps from one tube to the other. The first tube is lifted to show a now empty glass. The second tube is lifted and inside is the signed bill. Even more amazing is that the bill is inside the second glass, which is covered with the silk, which is secured with a rubberband. The spectator can remove the bill them selves.
