I love magic tricks where the onlookers are left completely puzzled, saying "That's impossible".

In this video, the magician removes a regular deck of cards from its box.
The cards are placed on the table and the box is set next to them.

To the amazement of the audience, the box has shrunk to an alarming size.
There is now no way that the cards will fit back in the box.

The reaction it causes is priceless.

See the video now.
