Card magic course is easy to learn.

The card magic tutorial is as follows:

Material: playing cards

Step 1: Prepare a deck of playing cards, any playing card will do.

Step 2: Let your friend randomly draw a card from here, show him the number of points in this card, and then tell him that I can guess the color and number of points in this card.

Step 3: Pack up the remaining playing cards.

Step 4: Then you pick up the remaining cards and tell him that I will put them down slowly. When you say stop, just insert the card in your hand, but don't let me see it.

Step 5: At this time, you can say it must be here, and then write down the color and points of the cards above you.

Step 6: This is one of your cards.

Step 7: Shuffle up and down before shuffling. Remember the approximate position of that card. Remember not to shuffle adjacent cards. You can also ask your friends to shuffle cards in the previous step 3, which will be safer.

Step 8: Then you find the card you just remembered among the opened cards, and find that the card on the right side of this card was drawn by your friend.

At this time, you can pretend to be mysterious and say that I can listen to the sound of this card and report it. Your friend must be surprised.
