Fortune-telling paper play _ fortune-telling paper

Your account is not detailed enough. There may be some details that you haven't noticed, but they have actually worked. I will give you a similar math game for your reference. There are six cards with many numbers within 63 written on them. You think of a number, and then tell me that those cards have the number you want, and I can tell you which number you want right away. In fact, the secret lies in the numbers on the card, which seem irregular, but in fact they are arranged in binary, such as:

The first one contains: 1, 3, 5, 7, 9, ...

The second contains: 2, 3, 6, 7, 10. ...

The third contains: 4, 5, 6, 7, 12. ...

The fourth picture includes: 8, 9, 10, 1 1, 12, ...

……

In the future, just add up the first numbers of the cards that you said have the number you want, and it will be the number you want.

It is estimated that the gentleman used a similar method. This is the first step. The second part is training parrots. Usually a millet sticks to a card, and the parrot will naturally take it out (in fact, it is to eat millet). After the conditioned reflex is formed, when you take out a stack of cards, just turn the card you need over (or turn it around) so that it can see a point on the card in front of the parrot (maybe you can't see it because of the angle), and it will peck it out. Then feed him another grain of rice.
