Die-A-Bolic trick - Viennamagic
The World's Smartest Die! While the magician has his back turned (or is completely out of the room) a spectator secretly places a die on the table in any position and remembers the number on top. The spectator then moves the dice around before the magician turns back and even though there's no possibility that the magician could have seen anything he can state the spectator's selected number instantly!
