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.
Post-It Surprise is a gimmick that can be used for several effects. You can make a sticky note change the writings or drawings on it, vanish, appear, change color or shape. Draw a car and make it vanish; draw a top hat and make a rabbit appear, etc.
