Effect: You remove five keys from your key case. One is handed to each of five spectators. A colored ribbon is tied to one key as a marker. You display a box. It may be nothing more elaborate than one that formerly contained candy. It is of the type where the sides of the lid are as deep as the sides of the box. There are holes through the sides of the box and lid. One leg of the bow of a padlock goes through these holes. It is locked. The spectators try their keys. Only the ribbon marked key will open the lock. After each failure, the first four spectators drop their keys in the box through a slot in the top. When the fifth spectator succeeds, the lock is removed and snapped shut through a button-hole of his coat. The lid is discarded.
The box itself is used like a tray. The fifth key is added to the other four, after the identifying ribbon has been removed. The keys are mixed and each spectator removes one and holds it concealed in his hand. Selections are made while your back is turned. A fter holding the lock for a moment to the back of each spectator’s hand, you announce who is concealing the key that will open the lock.
