Two.
Yes.
Four.
Yes.
And seven.
Ok, so I think
you removed a 9... Is that correct?
Correct.
YES!!!
Hi! Today I'm going to teach you
something to impress people.
So it's going to be in two parts.
First, I'm going to show you.
Secondly, I'm going to explain how it works.
To show you, I obvioulsy need someone!
This year, it's a bit different,
because I ask you, my subscribers,
who wants to come to shoot a video with me.
So I very recently asked on Twitter,
and Jules got back to me and came around.
So, I'm going to do the trick on Jules,
and we'll talk just after,
about how it works,
and how you can also do it.
So Jules, the idea is
that you're going to give me
a long sequence of digits,
the longest possible.
And I'm going to try and memorise the digits,
by using none of the techniques I usually use,
Ok.
And anyway it'll go too quickly for me to do so,
maybe I'll have to slow you down from time to time...
For this no to be overly complicated,
as I haven't really practised,
I'm not really good at it yet.
So we're only going to do it
with the Starbucks card on which
there are 16 digits, is that right?
That's it.
So it's like a bank card, we could do it with a bank card.
So you're going to slowly read to me
the 16 digits,
and every time you say a digit,
when I repeat it, or say "ok",
you can go to the next one.
Ok, here we go.
6
1
Oui.
3
Oui.
6
Oui.
5
Oui.
8
Oui.
9
Oui.
9
Oui.
3.
Oui.
4
Oui.
6
Oui.
5
Oui.
9
Oui.
2
Oui.
4
Oui.
7
Ok, all good for me.
Now, among those 16 digits,
you're going to choose 1,
don't say it to me,
then you're going to read the sequence again,
and skip that digit,
so you're only going to say 15 digits.
Keep the same pace,
and I'm going to have to determine
which one you skipped.
Ok, I'm listening.
