Vanishing Card Box
The magician takes out a box from his pocket, which holds a deck of
cards. The box has a window on top and an opening at one end. The card
case is clearly visible through the window and opening of the box. The
performer removes the card case from the box and sets the box on the
table. He opens the case and removes a card, say the Nine of Diamonds.
He declares that he will insert this card inside the card case over the
rest of the cards. He states that he will replace the case inside the
box, and cause the Nine of Diamonds to magically penetrate the deck, the
case, and the box. His actions follow his words, but nothing seems to
happen. Confused, the performer turns the box over.
To everyone's surprise, the entire deck of cards has disappeared, leaving the box completely empty! Instead of making the deck of cards disappear, you can change it into a matchbox, a silk or a miniature deck.
This is very easy to do, and extremely baffling. Supplied ready to work, complete with instructions.
