Amazing Mathematical Card Tricks Revealed

Hello again everybody. This is one of the coolest tricks that I've seen in a while. It's a self-working trick. You take nine cards at random. Three, four, five, six, seven, eight, nine. And you one, two, three, four, five, six, seven, eight, nine. And what you do is you have a spectator make three piles of three. So there's three, three, three. And then have them choose a pile and look at the bottom card of the pile. Let's say it's the five of spades. Now you have Then put that pile on top so their card is in the third position and you have them spell the card. F-I-V-E place the deck on top. O-F place the deck on top. Spades S-P-A-D-E-S put the place on the deck on top. Now the five of spades is going to be in the fifth position. One, two, three, four. There's a five of spades. Try it again with a different card. You have three piles. Flip them over. Let's just say they chose this pile with the Jack of Clubs. The top of the deck, they spell Jack, J-A-C-K, put the deck on top. Of, O-F, put the deck on top. Club, C-L-U-B-S, put the deck on top. The Jack of Clubs is 1, 2, 3, 4, in the 5th position. Again, just keep doing this to show you that it works with every card. Every time. It's a mathematical... I don't know how it's done, but... Um, let's say the Four of Hearts is the card, so you put that on the top, the Four of Hearts is the third card down, and they spell F-O-U-R, put it on top, O-F, put it on top, H-E-A-R-T-S, put it on top, and the Four of Hearts is one, two, three, four, five. Now, you can have fun with this. After they spell their card out, Don't just say, well, your card is the fifth card down. What you can do now is you can spell their name. If their name is John, you can say John, J-O-H-N. Turn over the next card, and it's your card. If their name is Mary, M-A-R-Y. Turn over the next card, it's your card. All right. Magic, M-A-G-I-N. There it is, magic. Whatever you want to do, you know it's the fifth card down, whatever their card was, so you can have a lot of fun with it. And it always is the fifth card, no matter how they spell it. Try it. It's pretty amazing. It's one of the coolest math tricks that I've ever seen. Thank you.
