Magician shows a transparent frame with a small card inside(Club 3). He shuffles the deck and asks a spectator say 'stop' for selecting one card. A Heart J is selected from a deck and put on the desk. He asks the spectator if he can still remember the card inside the transparent card. It must be Club 3. But after the magician covers the card with his hand, the club 3 suddenly turns to Heart J. And the selected card on the desk turns to Club 3, not Heart J.
