Bill Tube – Pro
The magician borrows a banknote, ask to sign it, and places it under a handkerchief.
He then gives the handkerchief with the bill inside to a spectator.
He then shows a padlocked brass tube.
The tube is given to another spectator with the key for the padlock.
The magician then shakes the handkerchief and the banknote doesn’t fall down to floor, it’s disappeared.
Immediately the spectator, that has the tube, is asked to open the tube and they find the signed banknote.
