1. First, the performance, the magician shows the card, so that the audience can check that there is no problem with the card, and then let the audience draw a card at will and sign it. Then the magician tore the card face to face into four pieces, then put the torn card in the palm of the audience's left hand and cover 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.

2. Specific operation. The magician prepared an ordinary deck of playing cards, rubber bands and pens. Show cards, let the audience randomly pick a card and sign it, then pick up the card signed by the audience and put it face up on other cards, and the other cards are also face up. The magician picked up the whole stack of cards vertically, facing himself and pretending to dry the signature on the cards. At this time, the thumb secretly pulls down the first card, that is, the signed card, and the right hand pulls up the second card. This method can only be done naturally, and the audience will not find it.

3. After that, let the audience put one hand flat, then put the four broken cards back in the audience's hand, and then let him cover them with the other hand to prevent the audience from finding them. At this time, the magician washes the cards in his hand at will, which is actually to secretly pull the signed cards to the last card on the back with three fingers, and at the same time turn up the upper part of the cards, secretly fold the last signed cards in half twice and press them under the cards. This is the key to magic. It should be as natural as possible and as small as possible. In order to prevent the audience from discovering the little tricks in their hands, we can use some misleading, 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, and let the audience pick up the hands that cover the cards. At this time, be careful not to let the broken cards stick to the audience's hands, which will expose the stuffing.

Finally, pick up four broken cards and insert them into the cards tied with rubber bands. At this time, a pile of cards are tied with rubber bands, half of them are placed on top, and four broken cards are placed on top; Below is a card with half face down, and at the bottom is a signature card folded twice. The magician picked up the card and slapped it on his palm. In the process of slapping, he secretly turned the card over, because the situation is similar from top to bottom, so the signed card will be on it. Look at the rubber band, hidden with four broken cards. You can say: I put the rubber band in my trouser pocket, and then let the audience open the card on it, and the audience will find that the card has been restored.
