I'm going to show you a very old trick, which
I used to keep in my top pocket and it's called
The Four Card Trick.
It only uses four cards.
It's a card trick with four trick cards.
I call them trick cards because although the
backs are ordinary they haven't got any faces.
All four of these cards are blank.
If I take one from the back and put it to
the front it turns into a Joker.
Now I want you to try to follow where the
Joker goes.
To start with it's one, two, three from the
top.
This is a sort of three-card trick with four
trick cards.
Now if I count the cards.
One, two, three, four.
Where do you think Joker should be now?
It was three from the top to start with, so
now it will be three from the bottom, but
no!
Whoever bets on that loses their money.
It's on the bottom.
I'll make it easier for you.
I'll turn the Joker around, so now you, not
only know where it is, you can see where it
is.
It's face up and is one, two, three from the
top.
So where do you think that the face-up card
is?
It's three from the top.
Yep, one, two, three from the top.
You're quite right.
If I turn it face down and of course all the
cards are once more face down except, of course,
for the Joker which if
you remember was face up one, two, three from
the top.
But I told you these were trick cards.
In fact, they're marked cards.
You see you can tell the Joker from the back
and anybody who knows that could always find
the Joker.
Would you like to have a look at them?
