I don't know the name of this one, a friend of mine showed me years ago. So, if anyone out there knows the name of it and who the originator was, I'd appreciate it. :)
I start off by asking the spectator to select any card, their choice, no force.
I lose their card in the deck and start to show one card after the other, none of which is their card.
The cards are all face down on the table, usually 6.
The spectator is asked to touch any two cards until one is left. I ask the spectator to think of their card. I make a gesture over their head, as if to grab the thought from thier mind....and 'sprinkle' the thought over the hand that covers the card. I ask the spectator to reveal the thought of card, and when they turn the card over...it's their card!
like I said...I don't know the name of this one...but I do this with a borrowed deck and it kills...everytime.
