Box Escape by Sachin.K.M

A random card is chosen. It is signed and put back into the deck. Shuffled and cut. Then put into the card box. Card box is displayed cleanly to show all cards are inside the box.
However the Magician tosses the box on the table & miraculously, the signed card jumps out of the box. Everything can be given out for examination at the end.

It uses a gimmick which you can easily make at home. A few inexpensive additional supplies will be needed.
