– The magician will let you choose a card and sign your name on that card. And he will tear off a corner of your signed card and put it on the paper and burn it.
– And he will take out an aluminum box from his pocket. And the magician he would invite any audience to open the aluminum box. Every time he opened the box, another box appeared. The box finally opened and the tear corner that you just burned has appeared.
Or a borrowed and signed coin disappears, and then reappears inside an aluminum box nest. Every time you open a box, there’s another box inside. Finally, in the smallest box, you will find the signed, borrowed coin. Amazing!
