An amazing routine that will have your spectators examining their sanity!
A spectator's selected and signed card is placed in the deck, and is pushed inside by that spectator. The magician explains that they are sitting at a magical table. The magician proves this by placing the deck on top of the table, and a sound is heard. The magician shows that the spectator's signed card has traveled under the table!
In a second phase, the signed card is placed in the deck, and the deck is placed in its box. The magician places his hand on top of the box, presses down, and squishes the box - the cards have vanished! They are found underneath the table! However, ONE card is still in the box - the spectator's signed selection.
