A spectator’s bill is signed and placed inside a silk with a rubber band. The silk rubber band and bill are now placed in a glass. the glass then covered with an aluminum tube.
A second glass is placed upside down in a second aluminum tube. The bill then jumps from one tube to the other. Amazingly the opening of the second glass is now covered with the silk which is held on by the rubber band and the bill is inside the glass under the silk. The spectator removes the glass and the rubber band and silk to verify it is his signed bill..
