My brother learned a new card trick today. I was the one who taught him the magic trick. When I showed to him the performance of the trick, he quickly asked me how to do it. When I already taught him the magic trick, my dad got a video of him. The trick goes this way. I will show you 4 cards. The 4 cards are the 4 kings. After I show you the 4 cards, I will put it on top of the whole deck. Then I will tell you a story. Let's say they will rob a bank. They entered the bank through the roof. Then I will put the first king into the bottom of the deck. Then let's say the first king will go to the first floor. Then I will put the second king in the middle of the deck then I will say that the second king will go to the second floor. Then I will put the third king in the middle of the deck then I will say that the third king will go to the third floor. Then I will make the fourth king stand up in the top of the deck then I will say that it will tell the other kings if the police is already there. Then the king announces that the police is here the three kings goes back to the top. Then I will show you that the deck is normal and that there is no duplicates.
