SIMPLE yet AMAZING MATHEMATICAL Card Trick REVEALED

Hello again everybody. Today I'm going to show you another easy card trick and tutorial. At the end of the video I'll be announcing the winners of the signed deck giveaway from my last video. Plus there's going to be another signed deck giveaway. So for this trick I'm going to need an odd number of cards. So first we'll give them a shuffle and let's say I take 17 cards. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. We'll flip them over and I'll shuffle the 17 face-up cards into the face-down deck. Give them another shuffle. So now you can see that they're all mixed in. And one more shuffle so they really get lost in there. And now what I'm going to do is divide the deck into two piles where each pile has the exact same number of face-up cards. Now there are a few rules. The first rule is that the piles do not have to be the same size. So there could be fewer cards in one pile than the other as long as they have the exact same number of face-up cards. The second rule is I can flip cards over if I want. And the third rule is I have to do this blindfolded or with my eyes closed. So I have over here a little table and you won't be able to see and I won't be able to see. So I'll set it down right over here and now I'm going to try and accomplish this without looking in about 10 seconds or less. So ready, go. 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. So I have two piles and now let's see how many face-up cards are in each pile. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 in that pile and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 in that pile. I did it. I can do it every time. So can you. It's very easy. Now let me show you how it's done. Okay this is a really simple yet very deceptive mathematical trick that works every time with any number of cards. If you're going to use the entire deck what I like to do is take about a third of the cards and you want to use an odd number. So let's say we take 17 cards. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Flip the cards face-up and shuffle them into the face-down deck. You tell the spectator you're getting the 17 cards lost. You can shuffle them again and now you can show the spectator the 17 cards are mixed in and lost in the deck. What you're now going to do is tell the spectator you're going to divide the deck into two piles and each pile will have the exact same number of face-up cards. Now there are a few rules. Rule number one, the piles do not have to be the same size. As long as they have the exact same number of face-up cards, they could be different amount of cards in each pile. Rule number two, when you're dividing the piles you can flip cards over if you want. And rule number three, and this is the most important rule, is you have to do this with your eyes closed or blindfolded. So put the blindfold on and all you have to do is take 17 cards off the top. So however many cards you start with is how many cards you take right off the top and then just flip them over. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Flip them over and now you'll have the exact same number of face-up cards in each pile. So this pile has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. And this pile has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. So that's it. Pretty quick, simple and impressive. Let me know what you guys think. Now on to the results and prize giveaway.
