A prediction is made and untouched from start to finish. The spectator is asked to think of a card. All done in their own mind without the use of any decks or extra props. They then change their mind so it is even more impossible for you to know their thoughts. After making a few decisions and having one card in mind they name the chosen card. You reach into your wallet to show a single card and that your prediction is correct.
