asked me to make.

First of all, here's the background.

A few weeks ago, I made this video with my neighbors, Danny

and Emily, all about numbers in a tin of spaghetti.

At the end of the video, I offered them 4 pounds each.

This is what 4 pounds looks like.

Or I offered to put this piece of paper on eBay and give the

proceeds to them.

DANNY: I reckon eBay.

EMILY: We should go for eBay?

DANNY: Yeah.

EMILY: OK, yeah.

BRADY HARAN: And the winning bid, which came from this chap

in Australia, was--

well, somewhat more than 4 pounds each.

Now, those of you who followed the auction desperately wanted

to see the reaction when the kids got the money.

So this is what 550 pounds looks like in one-pound coins.

EBay obviously have taken their share of things.

And here is that reaction you wanted to see.

BRADY HARAN: They're all one-pound coins.

BRADY HARAN: I don't know.

How much do you think is there?

BRADY HARAN: That's all yours.

So what would you do if you were 10 and 13 years old and

got given all that money?

Have a think about it.

DANNY: Thanks for that.

EMILY: Thank you.

BRADY HARAN: I've actually got a note here from Danny and

Emily, who have thought about it.

And this is what they spent it on--

a couple of treats for themselves; a present for

their sister, who wasn't able to be involved in the filming;

taking the whole family, including their mom and dad,

out for a family meal; and sponsoring a toilet in a third

world country through this scheme.

So they're giving a fair portion of what

they made to charity.

And that's not where the story ends, actually.

The people from Heinz, who make the Numberetti, they were

fascinated by the video.

They actually sent a couple of gift packs to the kids.

But they also sent all these tins of baked beans.

Danny and Emily's father actually works for a local

charity here in Nottingham helping people in times of

need with furniture and food and things like that, and

these baked beans are going to go to those people.

I think making YouTube videos is really fun and we do all

sorts of crazy things that you get to watch like going into

gold bullion vaults and rolling Yahtzees and

blowing things up.

-Whoa!

BRADY HARAN: And I don't think it's that often we think about

the serious things in life and people who are maybe less

fortunate than us.

This is probably a good time of year to think about it, and

this is probably also a good video in which

to think about it.

So under this video, I'm going to put some links to charities

and things like that that maybe you want to make a

contribution to.

This year, in particular, my life, through the people I

work with and also family and friends, has been affected

quite a lot by cancer.

And I guess cancer research is something that I think is

really important.

So I've actually set up a Numberphile page, a JustGiving

page, where you can give money towards cancer research.

And if that's something that affects you, or you can't

think of anything but want to contribute,

that link is below.

I'll include the toilet charity that Danny

and Emily gave to.

If you send in some suggestions, maybe I'll try

and include some others as well.

But it's just something to think about.

And thanks for all your support for Numberphile, and

thanks for everyone who bid on that piece of

paper for the kids.

It was a lot of fun, and we'll have more

Numberphile videos soon.
