Magic pocket

Before executing the focus, take 4 random cards and put them in your pocket. Take the deck of cards and ask the viewer to lay out the cards on the table in the closed form, then let the spectator choose without looking at the 5 cards, then the spectator should place these cards in a horizontal row. The spectator collects the remaining maps and puts them aside. The cards that are laid out in a horizontal row are numbered from left to right: 1, 2, 3, 4, 5. After that you turn away and the viewer should open any of these five cards, remember it and put it back, noting for itself its serial number, For example, he remembers: "This is the second card." Then you turn, collect these 5 cards from left to right, keeping their order, and put the received pile in your pocket, while saying that in your pocket you will separate 4 cards and in your pocket there will be the same card that the viewer chose. But in fact you will exchange, pre-cooked 4 cards, on this pile of five cards. You get a pile of four cards and put them on the table while saying: "Here are the 4 cards, in your pocket left alone, say the serial number of your card." The spectator says that this was the second card, and you in your pocket imperceptibly count the second card from the stack of five cards and get it out with the words: "This card, the king of diamonds".
