Imagine taking your mental demonstration to a whole new level.
The Numberic Cube is thoroughly mixed and your spectator freely thinks of ANY number on any side of the cube. 100% FREE CHOICE! (No forcing and nothing written down). In the process of solving an advance 5x5 cube, you are able to connect your mind with the spectator's and read her mind while BLIND FOLDED. This is as close to a real mind demonstration as one can get. The moment you finish solving the Rubik's cube you are able to reveal your spectator's thought.
Water proof and scratch proof high quality 5X5 cube
