#5 of only 8 pieces that were made!
Manufactured to a high-quality standard this baffling little wonder consists of a silver tube with holes in the sides, a little silver block with holes in the side that line up with the holes in the tube, and a little gold pin that fits through both, locking the block firmly in the tube. At your command the block penetrates the metal pin and falls in the spectator’s hand.
Everything can be handed out immediately (no switches, no additional pieces!).
This has a lot more in it than meets the eye. Very clever mechanical principle.
