You show a pack of cards to the audience, and ask one of them to select and sign any card. You pick the card with your fingertips. Now the signed card starts to bend very slowly. You control it - it stops or continues to bend slowly or quickly, it all depends on you... you don't move your fingers or your hands! When the signed card has straightened up, turn it, and let it be examined. At that point you can go on performing card tricks with the same pack of cards.
