Incognito Corner by Mario Tarasini

A normal deck of cards and a box is needed for this miracle. In the beginning a single card with a square drawn on it is placed under the cellophane.
After that the spectator chooses one card.
The magician tears off the corner of that card and throws it into the box.
One gesture and the corner of the card passes through the box and the card - appearing just under cellophane.
Another gesture and the corner goes back to the box.
After an effect the box and the selected card can be given to the spectator for inspection.
