With a simple session of cutting and glueing, you can make a device that provides a couple of
unusual effects. The visual change under the deck cellophane is great. But, it is stronger than
the second effect- card jumps back into card box- and so you have to design the 2º effect to make it
more important, or it ends up being an anticlimax.
The cellophane won´t last forever, so its
more practical for someone who opens decks fairly often.
