Duplex is a card rising effect from the mind of Kevin Schaller. It builds and improves on an old theme which allows you to show the box from all sides as well as allows you to show the box completely empty before you insert the deck.
A freely chosen and signed card is lost into the deck and the deck is put back into the box. Without any funny moves the signed card starts to rise all the way out of the box.
The best part of the trick is that there are no threads, wires, weights, rubber bands or magnets - just the box and the deck. No forcing. No cellophane needed. Box can be shown empty and from all sides - front and back. Automatic reset.
Note: You will require the new version of Bicycle box. Preparing the box is very simple and done in a matter of a few minutes. Kevin explains and demonstrates how you can build the gimmick. The method is a bit angly and best performed one-on-one or for a small group of spectators.
