Devious way to vanish a coin!
Borrow a quarter, and place it inside this small bank. Shake the bank so that your spectators can hear the coin rattling inside. On your command, however, the rattling stops abruptly. The coin has vanished from the bank! The bank can even be handed to the spectators for examination.
The coin can either disappear forever. Or another trick, like the Miracle Coin Box or the Coin Nest, can be used to make the coin reappear again, and you can make a complete routine out of the two tricks.
For a professional version of this effect, see the Rattle Box.
