Why does the psychic magic posted on the Internet keep that card in mind, and which card will disappear?

The cards in his mind disappeared because the five cards he took out later were the same as the previous six cards, but the colors corresponding to each number were completely different. In other words, the next five cards don't contain any of the first six cards at all. So it gives us the illusion of disappearing. This magic mainly uses the visual illusion caused by our brain's short memory. For example:

1. For example, the six cards he just took out were clubs 8, diamonds 8, hearts 6, spades 6, clubs 7 and diamonds 7. The magician will ask us to remember a card, but we often only remember the color of that card and the size of all the cards, thus ignoring the corresponding colors of other cards.

2. At this time, after the magician takes away the cards, he will take out the other five cards prepared, which are hearts 8, diamonds 6, clubs 6, hearts 7 and spades 7. At this time, you will find that no matter which card you choose, you will naturally think that this card has magically disappeared because of the wrong color or face number.

Psychic magic: magical arts related to the mind, such as prophecy, mind reading, control, induction, etc.

Mind magic is just mind reading, prophecy and perspective. It can predict the audience's psychology through suggestion, hypnosis, contact reading and NLP technology. Of course, performers also need a lot of experience and knowledge. Their success rate is closely related to the psychological differences of the audience, just as the same medicine may not cure the abdominal pain of two people. These technologies are only really trying to "read" people's thoughts. The most common process effect is to predict the behavior results that the audience wants, which are reflected by some graphics, numbers or other media.
