Two beautifully made brass boxes (1.2″ (3cm) in diameter) are displayed. Both have screw on lids, one having a red inset in the lid and base, the other a green.
A spectator drops a small coin belonging to the performer into the red box and the lid is screwed on. Then the spectator drops her own ring into the green box which is sealed.
With the red and green boxes well apart, the performer attempts to commit the perfect crime by swapping the two contents without touching the boxes!
The spectator herself unscrews both boxes and is amazed to discover the ring now in the red box and the coin in the green!
Excellent workmanship has gone into the making of these boxes. The handling is not difficult and does not require sleight of hand. This is a quality outfit!
