An absolutely STUNNING card effect!
Though it looks impossible, it's actually easy to do. Follow this: your spectator selects any card from a regular sized deck. After the card is placed back in the deck, it is found to now be HALF THE SIZE of the other cards in the deck! But that's not the end of it! When the entire deck is again spread out, THE WHOLE DECK has shrunk to miniature card size! Of course, you end the trick by bringing everything back to normal again.
To make it really easy to learn, the instructions for this one are on DVD!
