Hello, everyone!
This is a response video
to a card trick posted by MisMag822.
This is my second response video this week,
and we'll do something different next week.
So for this you'll need a pack of cards.
And you'll need five key cards, which I'm going to use
the 2, 4, 6, 8 and 10 of hearts.
You put these on top,
and then you'll deal out five piles
of five.
So you can just do this.
1, 2, 3, 4, 5, and you can do it again.
1, 2, 3, 4, 5.
Let's do this one more time. 1, 2, 3, 4, 5.
So you deal out five piles of five.
You ask your first volunteer to pick up the first pile.
This one over here.
And he picks it up, and he's allowed to pick
one of these cards
as his chosen card.
Now let's say he picks the four of clubs there.
And he's allowed to shuffle this pile up, as well.
So, he puts it back.
Your second volunteer can do this again
with the second pile.
And he'll pick a card, and he can shuffle it up.
And you can have up to five volunteers doing this.
You then collect these piles together.
But you can do that in any order.
So maybe I'll do this one first,
and then this one,
and then finally, the top left pile up there.
So we collect the cards together.
We then do this again. We'll deal out five piles of five
one layer at a time.
So we do five cards
at a time.
So 1, 2, 3, 4, 5.
But we can do this in any order we want.
We can go like this--1, 2, 3, 4, 5.
And then we could do it this way. 1, 2, 3, 4, 5.
And then we could do 1, 2, 3, 4, 5.
And finally--1, 2, 3, 4, 5.
So we can do it any way we want.
It doesn't matter, as long as we're doing one layer at a time.
We collect these piles up again,
in any order--you can collect them in any order.
So let's do this--top left,
and then top right,
and finally here, bottom left.
At this point, you can even give
the pile a cut,
like that.
And then finally, you will deal off
five cards off the top.
So 1, 2, 3, 4, 5,
let's put that down there.
And then do it again--
1, 2, 3, 4, 5.
Let's put that down there.
1, 2, 3, 4, 5.
Put that in the middle.
1, 2, 3, 4, 5.
Put it up there.
And finally, the last cards here,
1, 2, 3, 4, 5.
Let's put that up there.
And then you ask your volunteer
which pile contains
his chosen card.
So your volunteer would say
if we're looking for the four of clubs,
he would say this pile here,
in the middle.
Now, you know that your volunteer's
key card
was the two of hearts
in that original pile,
which is over here.
And notice--the two of hearts
is third from the top.
Which means that his chosen card
in this pile, which he indicated,
is also going to be
third from the top.
It is going to be
the four of clubs.
And you can do that for each volunteer.
If your volunteer happened to pick
the key card itself,
let's say he picked the four of hearts,
the second key card,
he would indicate this pile,
and you'd know that his key card
is the four of hearts
that would mean
that the pile he indicated, it's the key card itself--
it's the four of hearts,
so you can do that as well.
Now, how does this work?
I'm going to give you a chance to think of it.
And then I'll have a flash--
a flash fade--let's do that.
So, there you go--I hope you enjoyed that flash fade.
So I think this is a rather good trick,
but how does it work?
This is how we started off.
We started off with five piles of five,
which I've got here a pink pile,
a white pile,
a green pile,
a yellow pile,
and a sort of bluish pile there.
And the first pile here was this pink pile.
Now, it doesn't matter which of these cards
is the key card, and which is the chosen card.
It only matters that they start
in the same pile,
the pink pile.
And then what did we do?
We collected the piles up.
So let's do that.
And you could do this in any order,
but let's just collect them like this.
And then you deal out the cards again,
in five piles of five, but you do it one layer at a time.
So let's go.
1, 2, 3, 4, 5.
Finally, 1, 2, 3, 4, 5.
Now, the important thing to notice is
the chosen card and the first key card
are all in the same layer--there's a pink layer there,
third from the top.
They're all in the same layer.
So let's collect the cards up again.
So this is what we did.
We collected the cards up again,
you could do it in any order that you wanted.
So let's do this.
And let's finally do this center pile.
And you'll notice, if you look,
that the pink cards are
five cards apart from each other.
It's the same for the green cards,
they're five cards apart from each other.
The yellow cards are five cards apart from each other.
At this point, we were allowed to give them a cut.
And if we do that,
that doesn't change the fact
that the pink cards are still
five cards away from each other.
And then we counted off the five cards at a time
off the top of the pile.
So 1, 2, 3, 4, 5.
1, 2, 3, 4, 5.
Oh--let's try and get that right.
Finally, 1, 2, 3, 4, 5.
And let's do a couple more.
FIve up here,
and let's do five in the center.
Notice, again,
your pink cards--
so your first volunteer's chosen card,
and key card,
are still in the same layer.
It's changed. It doesn't matter, though.
The pink layer is now the second from the top.
So when your volunteer indicates which pile contains
his chosen card,
you know that his key card
and his chosen card
are in the same layer.
And that's how the trick works!
I think it's rather good.
And, as usual,
if you have been,
thanks for watching.
