Crystal Thought Condenser
A spectator selects a card from a standard deck. The performer displays a small solid crystal cube, which he explains will condense and focus thought rays, just like a lens focuses light rays.
The performer holds the cube and asks the spectator to concentrate on his chosen card. Suddenly an image of the selected card appears on the cube. Just as suddenly, it then vanishes. The cube can then be handed out for inspection.
Comes with Ace, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of all four suits. Use any of these cards for predictions. No face cards included.
