Terrific Effect The magician borrows a coin, which is marked for identification by the spectator. The marked coin is dropped into a small hardwood box by the spectator and the lid closed. The magician then gives the closed box a few shakes; rattling the coin inside. The box is given to a spectator to hold. When the spectator opens the box, the coin has vanished! The coin may be found in spectator's pocket, or nested away in some device; you can choose the outcome. The Rattle Box works great with the Spellbinding Boxes! The apparatus's size is: 3.5x2.25x1.5 inches.
