The Magic Box by Alfredo Gile

Amaze your friends with "The magic box"! Control people's mind with the power of ESP symbols ! You show five ESP cards on the table and a little white box with a prediction inside. Then the spectator shuffles the ESP cards and put them on the table face down. The performer leads spectator's hand slowly on ESP cards asking to say "Stop" when he wants. The spectator's choice is the symbol with the cross. Finally the spectator opens the box and shows the prediction: it's perfectly correct! 100% impromptu. There are no FORCES, GIMMICKS, ELECTRONICS or ASSISTANT used.
