An impossible change, right under their eyes
With Picture you can clearly show a card to your spectators, fold it and place it at your fingertips to instantly unfold it and show that the card has changed. WTF?
A card can change to another, a blank card can become printed… the possibilities are endless and not only applicable to cards!
Imagine showing a card to a spectator, just before putting it folded in his pocket. When you desire, just ask him to take it out and open it… the card has changed.
