Effect: The magician shows the card for the audience to check, and then asks the audience to draw a card at will and sign it. Then the magician himself tore the card into four pieces, and then put the torn card in the palm of the audience's left hand and covered it with his right hand. Then the magician took out a rubber band and tied it to the remaining cards. Then take out the torn card from the stage and insert it on the tied card. The magician picked up the card and slapped it on his palm. Untie the rubber band and let the audience pick up the torn cards, only to find that the cards have been restored. The effect is amazing.

Performance: The magician prepares an ordinary deck of playing cards, rubber bands and pens. Show cards, let the audience randomly pick a card and sign it (there is no problem here), then pick up the card signed by the audience and put it face up on other cards (other cards are also face up). The magician picks up the whole stack of cards vertically, faces himself, and pretends to blow dry the signatures on the cards. At this time, the thumb secretly pulls down the first card (that is, the signed card) and picks up the second card with the right hand (this technique is only useful) so that the audience can lay one hand flat, and then put the back of the four broken cards in the audience's hand, and then let him cover it with the other hand, in order not to let the audience find it. At this point, the magician randomly washes the cards in his hand. In fact, he used three fingers to secretly pull the signed card to the last card on the back, and at the same time turned the upper part of the card into the back side up, and secretly folded the last signed card twice and pressed it under the card (just the key to magic, so try to be natural and small. In order to prevent the audience from discovering the little tricks in their hands, they can use some misleading methods, such as asking the audience to raise or lower the cards in their hands. Then take out the rubber band to tie up the cards (naturally, tie up the signature cards folded in half below), let the audience pick up the hand that covers the cards (be careful not to let the broken cards stick to the audience's hands, which will expose the filler), pick up four broken cards and insert them into the cards tied up with rubber bands (in this case, the rubber band binds a stack of cards, with half of the cards facing up and four broken cards on them; Below is a card with half face down, and at the bottom is a signature card folded in half twice. The magician picked up the card and slapped it on his palm. In the process of slapping, he secretly turned the card around (because the situation is similar from top to bottom, the audience will not find it) and let the signed card be on it. Look at the rubber band, and at the same time hide the rubber band with four broken cards (you can say: I put the rubber band in my trouser pocket), and then let the audience open the cards on it.
