Looking for an amazing magic trick that's easy to perform and easy on the wallet? Look no further than the Red vs. Blue Card Trick! Amaze audiences as you change the back of a chosen card from red to blue! Shock them when you do it a second time but with an ending they'll never see coming!
What You Need
1) Two decks of cards. Ideally, both decks should have similar designs on the faces and backs. The only difference between the two decks should be the color of the backside (or some other small difference like a mark or sticker on the backside). For the purposes of this tutorial, we have selected one red deck and one blue deck. One deck will serve as our primary deck (red), while the other will serve as our secondary deck (blue). Before beginning the trick, you will need to select your Trick Card and your Dummy Card. Again, for the purposes of this tutorial, we have selected the 7 of Clubs and the 3 of Diamonds. The 7 of Clubs will serve as our Trick Card, and the 3 of Diamonds will serve as our Dummy Card.
Follow the steps listed below before performing for an audience:
1) Open both decks. Remove the promotional cards and jokers from the red deck. From the blue deck, remove the blue trick card (blue 7 of Clubs) and set it aside. From the red deck, remove the red trick card (red 7 of Clubs) and red dummy card (red 3 of Diamonds).
2) Take the red deck. Place the red 7 of Clubs on the bottom of the red deck. Now place the blue 7 of Clubs on the bottom of the red deck. Now place the red 3 of Diamonds on the bottom of the red deck. Your three bottom cards should be the 3 of Diamonds, the blue 7 of Clubs, and the red 7 of Clubs from the bottom-up.
Performing the Trick
From this point forward, you will be using the Red Deck you constructed during Set-Up when performing. You will no longer need any other cards from your Blue Deck, and it is recommended that you store it somewhere away from your audience to keep them from catching on to your trick.
Step 1: "May I Have an Assistant From the Audience?"
Step 2: The Hindu Shuffle: "Tell Me When to Stop..."
While gripping with your right hand, grab the red deck with your LEFT hand so that the palm is below the deck and your middle finger and thumb of your left hand are on the two long ends of the deck.
With the middle finger and thumb on your left hand, slide a few cards off the top of the red deck into the palm of your left hand. Be sure to keep your left hand below your right hand. Continue to slide cards off the top of the red deck until your assistant says “Stop.” (If you can slide cards off the top fast enough, it will appear as though you are shuffling through the deck. This shuffling technique is known as the Hindu Shuffle.)
Remember not to shuffle too fast, or you will run out of cards! Also, if your assistant doesn’t say “Stop” before you reach the bottom of the deck, don’t panic! Place the cards in your left hand on top of the cards in your right hand. Ask the assistant to stop you sooner, and repeat Step (2). Be sure to keep your blue card hidden during the process.
Step 3: "You Stopped on the Three of Diamonds!"
Step 4: "I Will Now Place the Three of Diamonds Back Into the Deck!"
Straighten-out the deck.
Spread the cards out on a flat surface with all the backs facing up.
Step 5: "One of the Cards Is Now Blue!"
Remove all the cards that are on top of the blue card and set them off to your right. Be sure to keep them in a neat pile, because you will use them again in Step (7).
Straighten-up the remaining cards with the blue card on top. Now hold the deck in your right hand.
Step 6: "I Turned the Three of Diamonds Blue!"
Pretending you picked up only one card, show your assistant the face of the 3 of Diamonds. It should appear as though the back of the 3 of Diamonds has turned blue.
Step 7: "I'll Perform the Trick for You Again..."
Slide the blue-backed card (the 7 of Clubs) off the top of the deck. Be sure to keep the back-side up and the card face hidden from view from your assistant and audience.
Place the 7 of Clubs face-down on a flat surface, but still in plain sight. Tell your assistant that you are going to perform the trick again, but are removing the “3 of Diamonds” from the deck.
The 3 of Diamonds should still be on top of the deck in your right hand.
Place the deck in your right hand on top of the deck you set off to your right in Step (5).
Straighten-up the deck.
Step 8: "You Stopped on the Seven of Clubs!"
Place the cards in your right hand on top of the cards in your left hand. Straighten-up the deck.
Step 9: "The Seven of Clubs Is Now Blue!"
Remember that it is not essential that you use specifically the decks and cards from this tutorial. The only requirements are that the two decks be nearly identical with the exception of one or two small differences in the back design that are easily recognizable (color is generally the simplest way to generate this effect), and that the values for the Trick Card and Dummy Card are selected in advance and prepared correctly.
