The magician displays a pack of playing cards to the audience by riffling it. All cards are shown to be different and blue backed. He takes the top and the bottom cards from the pack, waving those three times to show that all the other cards have turned identical! He then shows that the backs of all the cards have changed from blue to red. All the card fronts and backs have changed! To finish, the magician quickly reverts the entire deck back to a regular blue backed deck of playing cards. The trick resets instantly and can be repeated immediately. • Very easy to do.
