Take a look at your two special cards. One is a double-faced card, and the other is a doublebacked card. The audience is not supposed to know that these cards are trick cards! Put the double-faced card on top of the double-backed card. Have the top card (double-faced), angled toward the right so you can see the bottom card, too, just like a fan of cards. Hold the cards gently between your thumb on the top card and your first finger on the bottom card, towards the center of the cards. Show the cards to your friend by holding them as instructed and then turn your wrist over at the same time as you slide the top card to the left. When your wrist is turned, they will now see the other side of the double-faced card, believing it to be the second card. Then turn your wrist back and again slide the top card, this time to the right. Practice this turning motion, to get it right, so it doesn’t look like you are doing anything sneaky. Then take the top card (double-faced), show it to your friend and put it behind your back as you ask your friend what card that leaves in your hand. They will of course say the name of the card they just saw. With your hand still behind your back, simply turn the card over, and then bring it out with the other side showing, proving them wrong. For fun, this can be repeated a couple of times, but not too many, so they won’t get suspicious!
