1-2-3 Card By Bas Jongenelen
You show a deck of cards to a volunteer from the audience. Every card has a number written on the back. You explain that the cards are numbered from 1 to 52, in an order reflecting the structure of the human mind itself. The deck is fanned open to show that the cards are all normal – there is nothing out of the ordinary about them beyond the large numbers on their backs. The volunteer selects three cards, and these are laid on the table, face-up. The cards are turned over, and it is revealed that the volunteer has selected cards numbered 1, 2 and 3. Since this is far more than a coincidence, you explain that it is the product of mind control and behavioral psychology.
No sleight of hand
No rough/smooth
Just one single deck of cards and a permanent marker.
