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.
