A TRUE MENTALISM EXPERIENCE WITHOUT ANY FORCING!
Place a deck of cards on the table. An envelope is attached to the case using an elastic band and a post-it is stuck to the back of the case. Ask the spectator to choose any card in their head. He can change if he wants until you ask him to say his card out loud so you can write it on the post-it as a final choice. Take your prediction envelope, open it. Inside you will find a paper with writing "your card is in ... position" ask the spectator to count the number of cards written on the paper. Once arriving at the card, the spectator is asked to turn the card over. As if by magic it is the one he thought of.
