Multiplying Coin Tray
A small tray is displayed and several coins are borrowed and placed onto the tray. Three of the coins are picked up by the magician and the rest of the coins are dumped into a spectator’s hand and closed tightly. After magically causing all three coins in his hand to disappear, the magician has the spectator open their hand. The three coins have now reappeared back inside with the rest of the coins in the spectator’s hand!
