I Can Read Your MindOne person choose 4 digit numbersEx: I write a prediction from this number: Then, choose 4 digit number againEx:

I choose my number, that is

4 6 7 1

5 3 2 6

4 6 7 3

24669

Choose 4 digit number againEx:

I choose 4 digit number again

Then adding all numbers: The answer is

The answer is match with my prediction

3 5 8 9

6 4 1 0

24669

“The Secret”

3 5 8 9

6 4 1 04 6 7 1

5 3 2 6

4 6 7 32 4 6 6 9

9999

9999

For the result we just need to see first number that the volunteer choose:

So the result :4 6 7 1

9999 = 10.000 - 19999 = 10.000 - 1

2 -2

2 4 6 7 1 2 4 6 6 9

Magic 2This is called a market magic.I want to buy 5 fruits, that is apple, orange, banana, tomato, and pineapple, from 5 different seller.But we have to buy each fruits from different seller. For example we buy apple from seller 1, then in seller 2 we can buy other fruits except apple and so on.Here the price list from each seller:

Seller 1

Apple : 1200Orange : 2500Banana : 3800Tomato : 5100

Pineapple: 6400

Seller 2

Apple : 500Orange : 1800Banana : 3100Tomato : 4400

Pineapple: 5700

Seller 3

Apple : 1700Orange : 3000Banana : 4300Tomato : 5600

Pineapple: 6900

Seller 4

Apple : 3500Orange : 4800Banana : 6100Tomato : 7400

Pineapple: 8700

Seller 5

Apple : 2800Orange : 4100Banana : 5400Tomato : 6700

Pineapple: 8000

After you buy all fruits from different seller, sum all the price.But earlier you must have written a prediction that contains how much money that you spend.Now open that prediction.It must be 22,700 rupiahs.

The Secret

The secret is I have a formula that help you to make a price from each seller.Pick different 9 price let that be a, b, c, d, e, w, x, y, and z.Seller 1 : a, b, c, d, and e.Seller 2 : a+w, b+w, c+w, d+w, and e+wSeller 3 : a+x, b+x, c+x, d+x, and e+xSeller 4 : a+y, b+y, c+y, d+y, and e+ySeller 5 : a+z, b+z, c+z, d+z, and e+z

The contains of the prediction is always the same and depend on how much we make the price.Why is the price always the same even though we have different sequence when we buy from each seller?It’s because we have to but each fruits from different seller. Then when we buy apple at seller 1, we can’t buy apple again at other seller. So we get the pattern.

Magic 3

The third magic is about book magic.First you have to make a prediction. Write down at a piece of paper.Then pick a book and 3 dices.Pick a volunteer and order him/she to throwthe dices so we gonna get 3 random digits.Write down the digits, for example 663. Then what we gonna do is reversing that numbers, so we get 366.Now we’re going to subtract that numbers.

6 3 33 3 62 9 7

We get 297. Now we’re going to repeat the step. Reverse 297, so we get 792. but now, we must add those numbers.

2 9 77 9 2

1 0 8 9

We have final result, that is 1089. The first 3 digits represent the page at the book. And the last digit represent the words of that page.Which mean we have to open page 108 and find the ninth words of that page.After that, open your prediction that you’ve written earlier.

“The Secret”The secret is if we get a number then reversing and subtracting. Then reversing again and adding those numbers. We always get the same result, that is 1089.So we just need to write prediction based on the ninth words on the page 108 from any book you picked.
