  • For Mismag822, a maths trick by me.
    I have a horrible feeling I heard the phrase "the power of three" on an advert for 'Charmed'. How embarrassing.

    I was quite pleased with my 42 of Hearts reference :)

    Thank you, I felt obliged to be the most mathsy and to use a unique effect.

  • @singingbanana
    @singingbanana  15 лет назад +1

    Sorry. The trick is a bit clunky, but it is a trick I made up, nothing pro. A deck just seems to be a couple of 2s short.
    I think you can still do this trick with one deck, in this case I would just cannibalise some of the 2s from the row you are about to discard. Problem with that is that you have to talk your volunteer through it.
    Maybe we should just change the trick to two decks to make it absolutely smooth.

  • @singingbanana
    @singingbanana  15 лет назад +1

    I wasn't reading your mind from here.
    If you had picked two, then I would have known two was the missing number because you will always be able to put the cards in groups that add up to nine.

    Just to throw a message out there, I thought Plazity's trick was the best, I loved it. I felt obliged to come up with something mathsy, but I can't really see mine being performed.
    Out of interest, has anyone tried my trick and got it to work?

  • @singingbanana
    @singingbanana  15 лет назад

    The cards will always make piles that add up to nine, so you can predict the missing card.

  • @singingbanana
    @singingbanana  15 лет назад

    Not a mistake, 4*3 is twelve and I used an ace and a two to make 12 - I am not adding the values of the cards, I just use the ace as a one to spell out the digits of 12.

  • @Strijdparel
    @Strijdparel 15 лет назад +1

    O, that is a nice trick. I just have to work out a routine for it :)

  • @singingbanana
    @singingbanana  15 лет назад

    You're quite right. That is a weakness.
    It doesn't necessarily kill the trick if we reuse some of the aces from 5,5,A,A,6. We were only going to put them back in the deck anyway. But it's hard to talk your volunteer through that when your eyes are shut.
    If you really want to perform the trick, you could use two decks. Or two decks with the 10s and pictures removed. Depends how much effort you think it's worth!

  • @singingbanana
    @singingbanana  15 лет назад

    That's nice.

  • @singingbanana
    @singingbanana  15 лет назад

    You shouldn't need more than three of any kind, but you do need to put the old cards back in the deck. Starting with something like 555 is more tricky but doesn't necessarily kill the trick.

    Bi. I dare say that as impressive aa this presentation is, this trick is even better when the Magician does the first 2 steps behind the scenes sladh under cover and turns this into a 1 step Prediction where they do not reveal their methods.

  • @hiindika
    @hiindika 11 лет назад +1

    It'll be very easy to find out the value of the card if you do this way. (27- value of the remaining cards). In this case 27- 24 = 3.

    • @heatherswanson1664
      @heatherswanson1664 10 лет назад +3

      When you triple a number twice you're just multiplying it by 9. In the decimal system any number divisible by 9 has the sum of the digits = 9.

    • @bernardsboom

    • @htmlguy88
      @htmlguy88 7 лет назад

      actually the sum of the digits is divisible by 9. 111*9 = 999 sum of digits of 999 is 27 =3*9.

  • @TyYann
    @TyYann 15 лет назад

    Nice trick. Very niceuse of basic math properties. However, I got a question: are you sure you always have enough cards to spell the products? Is it possible (or not) to run out of aces (for instance) during the process?

  • @Saranet37
    @Saranet37 15 лет назад

    I don't really get it, but it looks interesting. Anyway, I like how you mentioned charmed in the description, that is one of my favorite shows! You are really smart, I could never think of that.

  • @singingbanana

    I completely agree.

  • @DXXDDXXDDX
    @DXXDDXXDDX 14 лет назад

    I haven't do it with cards but on a paper
    4 6 7 were the numbers I picked
    so as the trick has been done that would give me
    1 2 1 8 2 1
    and again
    3 6 3 2 4 6 3
    i picked 2 and my number
    so there should be only 2 groups but I got three groups????

    twice or more, and it will work. So try starting with one and keep tripling.

    at the end so what would i do then would i do the calucatibg of 9 when they have pickerd their card or b4

  • @DLmusifix
    @DLmusifix 15 лет назад

    what if you get a 5,5,A,A,6 in the second part? where will you get the other A? coz 3x5 is 15 that makes it two Ace's then 6x3 is 18 that needs another ace where will you get the other ace?

    I don't get what he did at the end. You can turn over any card, so why did he say the 3? I get that you can group them to add up to 9, but I don't get the "turn one over, and the one you turned over is a 3"

  • @luverlygir
    @luverlygir 15 лет назад

    My card wasn't 3 D:
    Though I did get 3 groups that added up to twice as much as 9

    I found a flaw in your trick. If you choose 1, 2 and 3 as the first 3 numbers, it won't work because at the end you will only get 5 cards not 6 or more

    @Qermaq 13 лет назад

    @elizze6 All the cards at the end total 9 or 18 or 27 or so no. If you total up all the cards and it is 3 less than one of those numbers, then the overturned card must be a 3. If they totaled 5 less, it'd be a 5.

  • @ax999
    @ax999 11 лет назад +1

    While I like it, there's something a bit disappointing about multiplying by 3 twice instead of three times.

    Hmm. Well, my card was a six, but even starting with 888, the end result was 126126126, so the maths would work....
    Then again, like people said, 3×3=9, so you're basically multiplying it by 9

  • @Boom2219
    @Boom2219 10 лет назад

    Ah, i see, so how many cards you start out with is how many sums to 9 that will be at the end i guess.

    • @ZombieKillerThe
      @ZombieKillerThe 5 лет назад

      just incase but here when you multiple a number by 3 twice you are actually multiplying by 9
      and when the number is 10 or more you use two cards (2:17) 3x4=12 and he used an Ace for the digit 1 and Two for digit 2.
      the best thing about a multiple of 9 is that all digits add up to a multiple of 9, so at the end he sorted all the face vaule of the card in piles that adds up to nine
      2, 7 (2+7=9) and 2, 3, 4 (2+3+4=9) but he couldn't sorted the second 6 card in a pile so he did 9-6=3
      for 7, the pile would have been 2, 3, 4 (2+3+4=9) and (3, 6) (3+6=9) and the second 2 will not be in a pile so 9-2=7.

  • @killeramaru
    @killeramaru 12 лет назад

    you can also do this by taking away all 10's, J's, Q's, K's, and two 7's, one 5, and one 8. have them pick a card and keep it face down. with the cards remaining, add them to 9, you will end up with cards that do not add up to 9, and if there is no cards left over that add up to 9 then it means they have a nine in their hand.... this method is a bit more tedious because you have to count more pairs of 9... but either way its fun.

    Does not always work. Many times you will run out of the same number cards when making double digits. Its a "by chance" trick.

    • @jnorris0712
      @jnorris0712 7 лет назад

      After your first multiplication by 3 your possibilities are 3, 6, 9, 12, 15, 18, 21, 24, 27. since you started with 3 numbers, you cannot make more than 3 of any one number (for example, 3 7s would give you 21, 21, 21. So you need 3 2s and 3 1s). After this you will have a maximum of 6 cards (since any one starting card can only give you a maximum of 2 cards). Multiplying these by 3 gives you a maximum of 9 cards (3 starting cards make 6, 6 make 9 since the first digit after multiplying by 3 will be either a 1 or 2). Of those 9 cards, you will only ever see the same number 3 times. Look above to the result (3,6,9,ect...). Lets look at the results for tripling those. They are broken up into the individual numbers (21= 2, 1) and then tripled again. So your resulting numbers will be the same ones above. The question is can you run out of enough cards to pull off the trick? No, because whenver you triple them you only ever get 3 of any value. For example: they choose 3 4s. They triple to 12, 12 , 12 (becomes 1,1,1,2,2,2). They then triple again to 36, 36, 36 (3,3,3,6,6,6). Take 3 6s. 18, 18, 18 (1,1,1,8,8,8) becomes 3,3,3, 24, 24, 24 (2,2,2,3,3,3,4,4,4). So no number should show up more than 3 times, no matter what the combination is so long as they break down the numbers to single digits and multiply by 3 again.

    what kind of stupid trick is this. its lame. I'm not impressed
