Ghost Corner by Ralf Rudolph

A corner of a playing card is torn off. The magician pretends to grab the card at the missing corner. Despite the fact that he is not touching the card he can still lift and turn the card while holding on to this missing corner.

The effect goes back to Lubor Fiedler. However, Lubor’s method is completely different and had the disadvantage that you couldn’t show the back of the card. With Ralf’s solution you can show both front and back while you are holding the card at the missing corner.
