Foresight is a powerful fusion between magic and mentalism by our friend, Oliver Smith. For those of you who love visual effects that fit right in your wallet, this is for you. It's extremely visual, easy to do, and gets jaw-dropping reactions.
The mentalist shows a black envelope. He asks a spectator to think of one of the kings and name it. Then he takes the cards out from the envelope, fans them and mysteriously, the thought of king will be the only one turned face up among the others. But that's not all... the thought of king is the only one with a different colored back.
