Show three Quarters and a small brass box with lid to the audience. Place the three coins in the box and put the lid on it. Ask a spectator to put out their hand and hold the brass box over it. Tap the lid of the brass box firmly, and amazingly one of the quarter coins PENETRATES RIGHT THROUGH THE BASE OF THE BOX, and drops into the hand of the spectator. The lid is then removed and the two remaining coins are removed.
Everything can now be examined. Sounds impossible, yet its accomplished very easily with the special box and gimmick coin provided. All you have to add to the set is 2 regular coins. A self working trick and no sleight of hand!
