The 5 Card Reveal Magic Trick: A Mathematical Mystery
Prepare to be amazed! This magic trick, known as the 5 Card Reveal, will leave your audience wondering how you managed to predict their chosen card. It's not magic, but rather a clever application of mathematical principles. Let's delve into the trick and uncover the secrets behind its success.
The Trick
The 5 Card Reveal trick relies on a simple but effective mathematical concept. Here's how it works:
- Choose Five Cards: Select five cards from a standard deck of playing cards. These cards will be your 'secret' cards.
- Arrange the Cards: Place the five cards face down in a row, in any order. Let's call them Card 1, Card 2, Card 3, Card 4, and Card 5.
- The Spectator's Choice: Ask a spectator to choose one of the five cards without revealing it to you. Let's say they choose Card 3.
- The Reveal: You now have the power to reveal the chosen card! Here's how:
**Step 1:** Turn over Card 1 and Card 2. Note the values of these two cards.
**Step 2:** Add the values of Card 1 and Card 2. For example, if Card 1 is a 7 and Card 2 is a Queen (worth 12), the sum is 19.
**Step 3:** Subtract the sum from the value of Card 5. For example, if Card 5 is an Ace (worth 1), the difference would be 19 - 1 = 18.
**Step 4:** Now, count the cards in the row from left to right. The card that is the same number as the difference you calculated is the chosen card! In our example, the 18th card from the left would be the chosen card.
The Math Behind the Magic
The trick works because of a simple mathematical pattern. The sum of the values of the first four cards is always equal to the value of the fifth card plus the number of the chosen card. This is because when you subtract the sum of the first four cards from the value of the fifth card, you are effectively left with the number of the chosen card.
For example, let's say the values of the five cards are as follows:
| Card | Value |
|---|---|
| Card 1 | 7 |
| Card 2 | 12 |
| Card 3 | 9 |
| Card 4 | 10 |
| Card 5 | 1 |
The sum of the first four cards is 7 + 12 + 9 + 10 = 38. The value of the fifth card plus the number of the chosen card (Card 3) is 1 + 3 = 4. Notice how the sum of the first four cards (38) is equal to the value of the fifth card plus the number of the chosen card (4). This pattern holds true for any arrangement of cards.
