Touch Of Genius by Simon Beckett

Let's set the scene here! You take a pack of cards, any cards they can be borrowed if you wish, or even sealed what better way to start a performance than have someone open the Deck and shuffle the cards! There is no need to prepare anything at all EVER! Now have the Deck cut by your spectator into 3 piles it could be more if you wish! Now for the magic You tell your spectators that you have been studying the art of premonition and would like to try a small experiment, you state that you did not cut the cards, that in no way did you influence them in anyway at all and finally that free will has been exercised. As your hand hovers over each pile you correctly name the three cards that are face down on the tops of each pile, the cards are then turned over to reveal that you really do possess that touch of genius! This can be done anytime, anywhere and with any Deck of cards, it is completely impromptu, and that's a rare thing these days!
