Imported from Israel, a tornado of magic! In fact, thats what its called. Tornado! Bring out a deck of Bicycle poker-size playing cards. The cards are absolutely normal, except for the hole drilled right through the middle of the deck--a hole big enough for a large nut and bolt. Ask a spectator to shuffle the cards, then to select one card and sign it. The choice is absolutely free. No force of any kind. They replace the card in the deck and the deck is shuffled. Next, you insert the bolt through the hole in the deck and tighten the nut onto the bolt. There is no way any card could be removed from the deck without tearing the card. Now for the magic! With no cover of any kind, you reach into the deck and magically remove one card! It is not damaged in any way! Somehow it has penetrated through the bolt! Turn the card over and, sure enough; it is the spectators signed card! They can keep the card as a souvenir, and all may be examined at the end. Tornado is a totally visual effect. Easy to do. The precision-made nut and bolt do all the work for you.
