A spectator is asked to think of a number between 1 and 12, to rotate the clock's hand on the chosen number, and finally to close the panel so as to cover the clock. Now the magician takes back the closed box and shows clearly that there is no way he could see the chosen hour, as the panel covers completely the clock. But, as he concentrates, the magician will reveal the exact hour thought of by the spectator!
