Imagine, you pierce a selected playing card with a straw.
You show the face and the back on the playing card.
Nothing to hide, it's just a playing card with a hole in the center.
You remove the straw and you blow through the straw.
The hole on the playing card is restored under the eyes of your spectators!
You give the card to the spectator and it is normal!
DVD, gimmick and material for remake included.
