Crazy Cube lets the magician read the spectator's thoughts – with little practice. It takes only a matter of minutes to begin reading minds with this clever piece of apparatus. A die is handed to a spectator by the magician, along with two canisters. With the magician's back turned, the spectator selects one number on the die and seals it inside the smaller of the two canisters. This canister is sealed inside the larger one. Despite the seeming fairness of the procedure, the magician can at any time, announce the number the spectator selected. Mind reading made easy! A great companion trick to our Color Vision Box. each one disproves the other method of divination.
