The spectator selects a card, and the performer tries to guess the card. He takes a small sticky note and sticks it on the back of the top card of the deck. After some concentration, he writes down a card to reveal that…it’s not the chosen one. But, the magician takes the card with the sticky note, gives it a shake, and visually, the writing on the sticky note changes! To reveal the correct card! The note is pealed off and given as a souvenir.
