A new approach to the Which Hand effect.

Effect:

The Mentalist borrows some coins, a participant selects one and is asked to look at the year of the coin. He is instructed to add the digits in the year together to come up with a secret number.

The participant hides the coin in one of his hands and is asked to bring both hands out in front of him in tight fists as if they both were holding coins so no one could tell which hand the coin is in.

After some concentration, the Mentalist is able to determine the participant’s secret number, which hand the coin is in, the denomination of the coin and the exact year!
