The magician shows five brightly colored aluminum rods and a small brass tube with a cap. Only one rod will fit inside the tube. While the magician's back is turned, a spectator pockets four of the rods and places the other, his selection, inside the tube, and screws on the cap.
When the magician turns around, he can instantly divine the color of the rod inside the tube. No sleight of hand or complicated memory work required. The trick is precision made and the apparatus does most of the work.
A wonderful, baffling pocket trick. Rods are approximately 2" high. Supplied complete with instructions. Individually boxed.
