From the Publisher:

Perform it on any glass door of any kind
On any car window, even the back window
Can be performed on a glass table top
Can be performed on a house window if you can get to the other side to complete the trick

A card is selected, signed, then mixed back into the deck.

Standing on one side of the window with the spectator, you ask them to push the cards up against the glass and mix them around in a jumble, holding them against the glass.

With the spectator holding the cards on the glass, you walk around to the other side.

You pause. You know that the effort you put into showmanship here is going to pay off in a few moments. Confidence is like blood running through your veins.

You tap on the cold, hard glass to emphasize the impossible nature of what is going to take place. You lower your hands and seemingly begin to extract one card-- slowly-- from the scatter that the spectator is pressing against on the other side.

To the spectators, it actually looks as if the card is sticking half way out of the glass... it takes genuine effort to pull it through. You can even take a few steps back.

There is a reason we call it Surgical Card Through Window. It looks like slow surgery on a plain slab of glass.

The doctor is in.

The card is SLOWLY turned over-- it is in fact their signed, selected card on the other side of the window.

Sit back, relax, and enjoy the show. Because when you turn that card over you are going to be watching one.
