The Mathematical Card Trick That FOOLS Everyone! (Self-Working)

[00:00:03]Any deck, anytime, you're about to perform something impossible. A truly mystifying effect that's not only super easy to learn, it's completely self-working. This is Coach Trick, [music] where small tricks create big belief in yourself. So, hit subscribe and keep leveling up. Now, grab a deck and let's uncover the magic.

[00:00:26]Okay, [music] as ever, let's start just by taking a look at the effect itself, and we're going to start with a shuffled deck. So, just hand the cards to a spectator. They [music] can shuffle these as much as they like. It's important they know the cards really are mixed. Now, we're going to ask the spectator to generate some totally random piles of cards, and you're just going [music] to demonstrate what you want them to do.

[00:00:49]So, you're just going to take the deck and you're going to deal a single card face up to the table.

[00:00:55]And here we can [music] see a seven.

[00:00:56]Now, on top of this card, you're going to deal some more cards to make this add up to 12. So, in this case, you're going to [music] deal five more cards. So, 8 9 10 11 12.

[00:01:09]And you're just going to hand the cards to the spectator, [music] and you're going to turn away so that you can't see anything.

[00:01:16]The spectator will now just take the deck, and they're going to repeat exactly the same.

[00:01:20]>> [music] >> And so, by the end of this, we're going to have totally random piles of cards.

[00:01:25]So, the spectator will just deal the next card to the table. Here we can see a king. Now, all picture cards count for 10. So, on top of here, they'll deal just two [music] more cards.

[00:01:36]11 12. And they'll continue [music] just by dealing the next card face up.

[00:01:42]So, here we can see an eight. So, to make this add up to 12, they'll deal just four more cards. 9 10 [music] 11 12.

[00:01:51]The next card here we can see is a two.

[00:01:55]So, on top of this card, they'll deal 10 more cards. 3 4 5 6 7 8 9 [music] 10 11 12. Now, in reality, obviously, they'll do the counting [music] silently so that you can't hear. And they're just going to repeat this process for all of the cards. Now, as a spectator gets towards [music] the end of the deck, if they don't have enough cards left over to make a pile [music] of 12, you can just ask them to take all of these cards and just place these to the side.

[00:02:25]At this point, [music] you can now turn back around towards the cards.

[00:02:29]With totally random piles now on the table, >> [music] >> you can take the remaining cards here and just explain that these are sensor cards. [music] Because these cards are actually inherently connected to all of the cards on the table. And you can actually use these cards [music] to pick up information about the others. So, you're just going to sense these cards for a second.

[00:02:50]Just trying to pick up information about the other cards. Okay, just there. And once that's done, you can then place [music] these cards to the side.

[00:02:59]You're now just going to take a piece of card or paper. And on here, you're going to note down a single number as your prediction.

[00:03:07]So, just noting down that number secretly.

[00:03:10]>> [music] >> And once you've noted that down, you can then just fold it up so that it's totally [music] hidden.

[00:03:16]And then just place it on the table.

[00:03:20]At this point, you can just recap that from a shuffled deck, the spectator [music] has dealt random piles of cards to the table. And on the bottom of each pile [music] is a totally unknown card.

[00:03:31]You're now going to ask the spectator to use [music] the total of those unknown cards in order to generate a completely random number. So, just taking each face-up card one by one. [music] So, here, that's nine.

[00:03:46]Plus three is 12. Plus a king, which which a 10, so that's 22 plus seven, 29, plus another seven, is 36 plus 10, is 46 plus eight is 54 and finally plus two is 56. So the total of the face up cards here is 56.

[00:04:13]And once again, you can just emphasize that's totally random. [music] There's absolutely no way that anyone could have known what cards would be dealt or what number they would generate.

[00:04:23]You can now just bring in your pre-written prediction here, reminding everyone that this was written before any [music] cards were even revealed.

[00:04:31]And you can now just open this up.

[00:04:36]Reminding everybody [music] that the total of the cards is 56. You can now reveal your prediction [music] just happens to be an exact match in this instance.

[00:04:50]56 Okay, so let's take a look at the secret to this effect.

[00:04:58]>> [music] >> Now, all you need here is just a complete deck of 52 cards and a spectator really can shuffle the deck as much as they like. It all adds [music] to the impact. You're then just going to demonstrate to the spectator what you want them to do [music] by dealing the top card face up to the table.

[00:05:14]So here we [music] can see a nine.

[00:05:15]You're now going to deal some more cards on top of this to make this add up to 12. So on top of the nine, you're going to deal three more cards.

[00:05:23]10, 11 12. You then just hand the cards [music] to the spectator as you turn away so that you can't see anything.

[00:05:32]>> [music] >> And the spectator will now just do exactly the same, dealing the next card face up and then dealing [music] some more cards on top so this adds up to 12.

[00:05:41]So on top of the three, they'll deal nine more [music] cards.

[00:05:47]Now just a note here, aces will count for one and all picture cards will count >> [music] >> for 10.

[00:05:52]And the spectator will now simply just continue this exact process for all of the cards.

[00:06:00]Now, as the spectator gets towards the end of the deck, if they don't have enough cards left over to make a pile of 12, just ask them to take all of the leftover cards and place these to the side. And with that done, you can now turn back around towards the cards.

[00:06:18]At this point, using just the cards on the table, you're now going to calculate your prediction number, [music] and here's how. Firstly, if there are any leftover cards here, you're going to take these cards [music] and pretend to sense them. But actually here, you're just secretly going to [music] count the number of cards. So, in this instance, there are four cards.

[00:06:37]You'll just note this number and then place these [music] cards to the side.

[00:06:41]You're then going to count the number of piles on the table. So, here we can see there are six piles.

[00:06:47]From this total, you're going to subtract four. So, 6 - 4 is 2. [music] And then you're going to multiply that by 13. So, 2 * 13 is [music] 26.

[00:06:58]To that total, you're then going to add the number of spare cards over here. So, 26 [music] add four is 30. And that number is going to be your prediction number.

[00:07:10]>> [music] >> You're then just going to note that number down on a piece of card or paper.

[00:07:13]So, in this instance, the number 30.

[00:07:16]You can then just fold that up and place it on the table.

[00:07:19]>> [music] >> Remind the spectator at the bottom of each of the random piles is an unknown face up card. You're now just going to ask the spectator to total those cards together in order to get a random number. [music] So, in this instance, 9 + 3 is 12, add the four is 16, add the seven is 23.

[00:07:38][music] Add the two is 25, and finally add the five, is 30. Emphasizing that that is a totally [music] random number, you can now reveal your prediction.

[00:07:50]And it will always be an exact match. In this instance, [music] the number 30.

[00:07:57]Go and amaze.

[00:08:00]And that's how it's done.

[00:08:02]Remember, the cards are just the tool.

[00:08:04]The real result is discovering what you're capable of [music] when you give yourself the chance. So, keep creating those moments, and I'll see you in the next tutorial. [music]
