A wallet fashioned and finished to meet one goal: Be the best wallet with which to perform the effect Card to Wallet. The basic workings are described in Regal's best-selling book Interpreting Magic, but David decided to manufacture a perfect version. The Regal Cop Wallet was built from the ground-up with exacting precision and attention to detail. What is the smoothest loading wallet possible? (provided, of course, he did all the addition correctly in steps 3-5 above.)Ī very special thanks to Bob Kurosaka, retired math professor, for generously sharing these tricks with Curious and Useful Math.THE REGAL COP WALLET by David Regal DVD. If your subject selects any number between the last five (#21 through #25) and divides it by the number above it, he'll always get 1.618033989., which just happens to be the Golden Ratio. With great concentration you divine the number presently on his calculator: "I'm getting a one. Remind him that you do not know his original two numbers or any of the 25 numbers, that you do not know which of the 25 numbers he selected right now, and therefore you cannot possibly know the number on the display. Click here to see an example of all this.

Select any number among the last five on his list, and divide by the previous number (the number above it).

Continue this process (add the last two, write the sum) until he has 25 numbers on his list.

Add the last two numbers and write the sum on the next line.

Add the two numbers and write the sum on the third line.

Write any two whole numbers on the first two lines.

Give someone a sheet of paper and a pencil and tell him to do the following This trick takes considerable time, but the effect is spectacular. No reason has been found for this phenomenon. 7731 - 1377 = 6354Īmazingly, all four-digit numbers (not multiples of 1111) end up in the 6174-loop. Subtract the smaller number from the larger number. 1377Īrrange the digits in decreasing order. Let's try 7173 Arrange the digits in increasing order.

Repeat steps 2, 3, and 4 with the result, and so on.

Subtract the smaller number from the larger number.

Arrange the digits in decreasing order.

Arrange the digits in increasing order.

Since \(10001 = 73 \times 137\), the eight-digit number will be divisible by 73, 137, and the original four-digit number. Why does this work? Entering a three-digit number twice (12341234) is equivalent to multiplying it by 10001. After he has done so, dramatically command him to look at your prediction on the paper.

Next, announce that he can now divide by his original four-digit number.

Announce that the number is divisible by 137 and have him verify it on his calculator.Now have your friend select a four-digit number and enter it twice into a calculator.For this trick, secretly write 73 on a piece of paper, fold it up, and give to an unsuspecting friend.Since \(1001 = 7 \times 11 \times 13\), the six-digit number will be divisible by 7, 11, 13, and the original three-digit number. Why does this work? Entering a three-digit number twice (123123) is equivalent to multiplying it by 1001. If you wish to predict Bad Luck, have him divide by 7 in step 3 the final answer will be 13. You can use this to predict Good Luck for him. Have him divide by his original three-digit number.Announce that the result is also divisible by 13.From across the room (or over the phone), announce that the number is divisible by 11.(For example: 123123) Have her concentrate on the display. Have someone secretly select a three-digit number and enter it twice into her calculator.We get 16.Ĩ is also even so we divide by 2 again and get 4.ġ is odd, so we multiply by 3 and add 1. (\(40 \div 2 = 20\))Ģ0 is even, so we divide by 2 and get 10.ġ0 is also even so we divide by 2 again and get 5.ĥ is odd so we multiply by 3 and add 1. 13 is odd, so we multiply by 3 and add 1. The sequence always ends in the "loop": 4.2.1.4.2.1.Įxample: Start with 13.Repeat the process with the new number over and over.Pick a whole number and enter it into your calculator.(By the way, that 8-digit number (12,345,679) is easily memorized: only the 8 is missing from the sequence.) If he selected 3, the final answer is 333,333,333. How? If he selected 5, the final answer is 555,555,555.

Have the person show you the result so you can tell him the original number he selected.

Now have him use a calculator to first multiply it by 9, and then multiply it by 12,345,679 (notice there is no 8 in that number.).

Have someone pick a number between 1 and 9.
