EFFECT: The performer shows a transparent tube and pushes a small handkerchief through it. He then takes a sheet of paper, covers the cylinder, and wraps it up. He then hands the cylinder to a spectator to hold. At some point later in the performance, the spectator may unwrap the cylinder to find the silk has vanished!
