The amazing "Color Changing Deck"
The Magician sets a deck of cards on the table and removes a pen and small piece of paper from his pocket. He writes down a prediction on the piece of paper, folds it and places it onto the table. Removing the deck of cards from the box, he explains that sometimes magicians may try to influence you to pick the card they want you to pick. They might say “King you choose a card for me?”, meaning they may try to trick you into choosing a king. In order to make for the fairest and most random choice possible, the magician removes a pair of dice from his pocket and hands them to the spectator. The spectator rolls the dice and the numbers are added up.
The magician begins placing cards face-up onto the table as he counts down to the number determined by the dice roll. He stops at the Ace of Spades and sets it aside. The spectator is then asked to open the prediction and read it out loud. The prediction reads “You will choose a red card.” The spectator laughs, for the prediction is not accurate. The magician then turns the Ace of Spades face-down showing that it has a red back. Realizing the spectator is still not impressed, he picks up the remainder of the deck, snaps his fingers and turns the cards over revealing that all of the cards in the deck now have “blue” backs, making his prediction match.
Items required include; A deck of blue-backed playing cards, a red playing card box, 1 red-backed card (for this example we will use the Ace of Spades), a small piece of paper, a pen and 2 ordinary dice. Begin by removing the Ace of spades from the blue-backed deck of cards. Place the red-backed Ace of Spades face-up onto the table. Then place any 12 random cards face-up on top of that. Then place the King of Hearts face-up on top of that. The rest of the deck is placed face-up on top of that and all of the cards are placed face-down into the red card box. The paper, pen and dice are all placed into the pocket.
The pack of cards is placed onto the table so that the spectator can see that it is red. (NOTE* It is important not to mention to the spectator that the cards are red, but rather let them come to that conclusion on their own). Remove the paper and pen from your pocket and write “You will chose a red card” on the piece of paper. Fold the small piece of paper in half, then in half again so that the spectator cannot see what you wrote and place it in full view onto the table. Remove the pack of cards from the box and hold them in your hand face-down (again reinforcing in their mind the cards all have red backs). Make sure not to allow any of the blue-backed cards to be seen. Place the empty card box into your pocket, then turn the cards face-up and begin to look through them.
Explain to the spectator that sometimes magicians will try to trick you into choosing a specific card, for example if I wanted you to choose a king I may say something like “King you choose a card for me?”. As you say this phrase, search for the King of Hearts and show it to the spectator. Place all of the cards that are above the King of Hearts face-up onto the table. You should be left with a packet of 14 cards in your hands (King of Hearts on the top, 12 random cards below that and the red-backed Ace of Spades on the bottom). Place the remaining cards in your hands face-up onto the deck (the red-backed Ace of Spades should now be in the 14th position from the face of the deck).
Remove the dice from your pocket and hand them to the spectator to examine. Explain that they will roll the dice and the number that is rolled will decide which card is chosen. Once the spectator rolls the dice, add the two numbers on the top-side of the dice together. Then explain that to make it even more random, you will also look at the numbers on the bottom-side of the dice and add them up too. Then add both numbers together. The total will always add up to 14 (for example: if the spectator rolled 2 “sixes”, add them up to equal 12. The number on the bottom side of the "six" is the “one”. add both “ones” together to equal 2. 12+2=14). Once the number 14 has been chosen, place the dice back into your pocket (NOTE* do not allow the spectator to examine the dice after the number 14 has been chosen or they may try to add up the sides and discover the secret). Count down to the 14th card which is your Ace of Spades and place it aside, face-up onto the table. Allow the spectator to open the prediction and read it out loud. Turn the face-up Ace of Spades face-down and make a joke about how your prediction is accurate because the card is technically “a red card”. Then gather up the rest of the deck face-up into your hands and snap your fingers. Turn the deck face-down revealing that all of the cards now have blue backs, making the Ace of Spades the only red card in the entire deck!
