Extreme Science and Christmas Make Blue Peter

On today's show, we've got wind, rain and a giant cloud in the studio,

so, you know what? I'm not taking my chances.

Linds, we don't need to be quite that prepared.

Oh, really?

THUNDER AND LIGHTNING RUMBLES

APPLAUSE AND CHEERING

Hello, and welcome to live Blue Peter!

Coming up on today's show, I'll be showing you how to make

your very own Blue Peter Christmas card 2015.

It is a cracker!

POPPING

Literally. SHE LAUGHS

This hero of a scientist, Greg Foot,

is back in the house with a belter of a weather experiment.

What can we expect, my friend?

Oh, I'm only going to fill the whole studio with a cloud.

I cannot wait for that. And that's not all.

Check this out.

Woohoo!

Oh, yeah!

'I get put through my paces in the air and in the water,

'all as a part of my wind turbine adventure.'

That looks so cool.

And, because we're talking about extreme weather today,

we want to hear from you, it's a live show, isn't it?

So get in touch with us and tell us if anything

could pour out of the sky today for you, what would it be?

-BOTH:

-And why?

Head to the website.

We will read your comments at the end of the show.

Now, you can probably tell the man, the myth,

Barney Harwood is not here. He is on holiday.

However, before he left, he did a spot of gardening,

extreme gardening, at extreme heights. Check this out.

JUNGLE SOUNDS

MONKEYS SHRIEK

I think I'm lost.

I'm never going to see Radzi again.

You know you can use the paths, Barney?

Yeah, I'll just use that. Ooh!

'OK, so I'm not actually lost in the jungle.

'I'm in the world's largest indoor rainforest at the Eden Project

'in Cornwall, home to over two million plants.'

'Some of the tropical plants in these giant domes, known as biomes,

'can grow to be seriously tall.

'And I've heard they need my help to trim them.

'Let's get some gardening gear on.'

Well, I wasn't expecting this.

But I am kitted out to do some extreme gardening.

And the girl to show me the ropes is Hetty.

Now, she says she hangs around here, but, erm...

I haven't seen her. Have you seen her anywhere?

Hey, Barney? You ready?

'Ah! There she is.

'Hetty is one of the horticulturalists here,

'who looks after all the plants, and she's taking me right up

'into the tree canopy to start pruning.'

'I'm using a technique called jugging,

'where I make myself go higher by pulling on my rope.

'It sounds really hard, but it's actually surprisingly easy.

'And before no time, I'm up in the trees.'

Why do you have to prune these?

Tropical trees grow really, really fast.

And they get so big that they start to grow into the side

of the biome structure.

How do you maintain the conditions of a real rainforest?

-So we've got this fantastic structure above us.

-Yeah.

Which is really efficient.

As soon as that sun comes out, it captures all the heat

and helps to keep it really nice and warm.

It can get up to about 43 degrees in here.

Maybe higher, right at the top.

That's hotter than going to Spain on holiday

-at the height of summer, isn't it? That's...

-Yeah.

-That's real heat.

-So if I trim this one.

-Yes, please.

-Just about there?

-Yeah, that'll do nicely.

-Nice clean cut.

Big branch falling.

Coming down.

'And, while we're up here, Hetty wants to show me some of the sights.

We're about eight metres up today,

which is quite a little climb for us.

-That big tree you can see over there, our kapok.

-Yeah.

-That's 30 metres high now.

-Wow.

And from the top of that platform down to the ground is 50 metres.

-That's insanely high, isn't it?

-It is.

-Shall we go down?

-Yes.

'So there you have it.

'Pruning a rainforest, tick.

'But it's not just tropical trees growing here.

'There are all kinds of plants from around the world,

'including South American cocoa beans.'

Wait, did I just say cocoa?

-HE GASPS

-I did!

Well, you know what that means.

That means we're surrounded by chocolate.

Everyone stop filming, we're having lunch.

Come on, Barney! We've got work to do.

'What? More work? Oh, OK.

'Next on the list is picking papayas.'

-I'm going to cut and you're going to catch.

-Ah, this is cool.

So first one.

-Got it, got it, got it!

-Whoa!

Yes! First one in and then it's just splattered everywhere.

-Whoa!

-Yes!

-Whoa!

Yeah, look at that!

Got it, got it, got it!

Yes, we're in! Beautiful.

I think I broke the camera.

'After the fruit is picked, it goes on display,

'so that visitors can learn about the different types of food

'grown around the world.'

OK, Hetty, so far we've climbed to the top of some trees,

done a bit of pruning.

We've picked some fruit, that was cool.

You've told me that we can't have any chocolate. What's next?

So the final job today involves chillies.

-VOICE ECHOES:

-Chillies.

-DRAMATIC MUSIC

'Not chillies!'

MUSIC: Burn by Ellie Goulding

'I still have nightmares about that live chilli-eating challenge.'

# And we gonna let it burn. #

LAUGHTER Barney's gone.

-ECHOING: Barney's gone.

-Barney? Barney?

-Barney?

-Yeah?

Hi, Hetty. Chillies.

Erm...love chillies.

Wh...what, er, what does it involve?

We're going to harvest some chillies.

-We're going to harvest them?

-Yeah.

-We're going to pick them?

-That's all we're doing?

-That's all we're doing.

I love picking chillies! Show me where they are!

FLAMENCO MUSIC

-IN SPANISH ACCENT:

-'Say hello to the habanero chilli.

'These little fellas are hot. In fact, they are so hot,

'we have to wear gloves before we can start picking them.'

Why do think it's important to grow lots of different things?

And why here at the Eden Project?

Well, we want to show people how dependent they are upon plants.

Without plants, we wouldn't be eating, we wouldn't have shelter.

A lot of the clothes that we are wearing are made from plants,

so we are here to reconnect people.

Well, I happen to know from experience that a jalapeno,

which is the kind of pepper you would get on your pizza,

it's got a little bit of a tingle to it, hasn't it?

-A little bit spicy.

-Mm-hm.

Well, these are 200 times hotter than one of those.

That's how bad boy these are.

They look nice and juicy, though, don't they?

Mm, do you want to try one?

No, thank you.

MUSIC: Burn by Ellie Goulding

'Yeah, steady on, Hetty.'

I've got to say, I had a brilliant time here at the Eden Project.

I can't wait to get back in the Blue Peter garden.

I'm going to plant a massive papaya tree.

Oh, and don't worry, Radzi, I've er...

I've got you some chillies.

FLAMENCO MUSIC

I loved that chilli challenge. Very funny.

But now it's time for one of our annual highlights because

for years and years, Blue Peter presenters have been showing you

how to make your very own creative Christmas cards.

They're always great and you can make them cheaply and easily.

We've made so many over the years.

They're very easy to make.

Each card has a pipe cleaner.

All you need is some brightly-coloured card,

scraps of fabric and glitter.

It is a card with a difference, as it has a built-in snow globe.

This card is really personal and one that money can't buy.

And there is that glitter.

And there we have a finished star.

And there we have our finished Christmas card.

I'll give it a little shake there.

-Woo!

-APPLAUSE

It really is the best make of the year, isn't it?

You're going to love what we've come up with for 2015.

Have a look at this!

It's your very own Christmas card, with a surprise cracker.

SHE LAUGHS

We love it and I'm going to show you exactly how to make it.

So, for that, you are going to need the following things.

A template from the Blue Peter website.

You'll need some corrugated card, so basically a cardboard box.

Some sparkly or coloured card,

thin, shiny plastic and, of course,

loads of photos of your family and friends.

You can make it really personal and really fun.

It really is such a good make, so listen carefully.

The first thing you need to do is head to that

trusty old Blue Peter website. Get yourself one of these templates.

You can see it's kind of split in half there.

You've got an H shape

and then you got the end of your crackers there.

So you need to cut around those and, when you've done that,

grab your corrugated card

and your shiny paper, like so,

and then you need to, once again,

draw around them, all the way around the outside of the stencil

and cut out those shapes.

So, once you've done that...

Try and be neat, because you will need those shapes to be pretty exact

if you want your mechanism to work.

So...we're going to use the H first.

You can see I've cut around nice and neatly there.

Take your time with that. Ask an adult to help.

And, with the H, the first thing I'm going to do

is grab my bit of plastic.

You can see there, I've just got a little strip of plastic

and all I've done there is used it

off a previous greeting card.

Nice and easy, but any plastic really will do.

So...wrap it round your H, like so.

It can be a bit fiddly, this bit, so take your time.

And make sure it's not too tight,

otherwise your mechanism isn't going to work.

So I'll just stick it nice and neatly there. And you should see,

when I hold it up, that that kind of just moves around.

It's very delicate at this stage,

but it is moving and that's going to make

our cracker pop a little bit later on.

Now, grab your two shiny bits.

These are your cracker ends

and turn one of them over, like so.

Now, you've got your two ends and I've just put a little bit

of double-sided sticky tape on the end there.

So, grab your shiny side and just simply stick that down,

make it really neat and line-up...

Can you see that?

..with the edge of your kind of H shape there.

Then turn it over, like so,

grab your other bit.

And then stick it,

like so, along that H.

There we go. And, once you've patted it down, hopefully this will work...

Eh! It certainly does!

And, once you've done it nice and neatly,

it should look something like this one.

And it should really kind of pop like that.

Now, if I grab this one, I'll just show you the back of it,

because it is still looking a little bit messy at the back there.

So, the next thing you need to do...

grab your paper, like so.

I've gone for silver, cos it's nice and festive.

Should be A4 size. Cut that in half.

Then, all I have done is just simply folded it in half again, like that.

Now, we are going to plonk our cracker into the middle of the card.

I am just going to use a little bit of double-sided sticky tape, like so.

And then, neatly, hopefully, I am just going - oh, this side! -

I am just going to plonk it in, like that. There we go.

Hopefully, that will stick down.

And then, fold your card over,

like so. Make sure your sides are out, so they don't get stuck down.

Once I have gone along, like that,

it should work, fingers crossed! There we go!

Now it's time for the fun bit, cos we get to decorate our cracker

and make it look really realistic.

So, for that, I have just, kind of, done a cracker shape, really.

You can do anything you want. That is the whole fun part of this make -

you can make it your own.

I am going to make it look like a cracker, with my cracker middle.

Boom. And then, time for a bit of decoration.

So, it is Christmas, of course. I have gone for a beautiful little

Christmas pud. That is made out of foam. We have just used a pen,

to make the raisins on there. And some little baubles. Very pretty.

Then, of course, all crackers have a little bit of glittery ribbon

on the side. Again, we have used some foam there.

I am going to put it on the side,

so it looks like one bit of the ribbon.

And on the other side here. It is really starting to take shape now.

But we need our little surprise in there. So, I thought,

"What does everyone want at Christmas?" Of course -

Barney and Radzi's faces. That's definitely what I want.

So, I have got Radzi on this side, in his little winter scarf.

Look at him! And then, Barney, cos I'm missing him today,

I have got him in his little winter scarf, there, as well!

So, we are getting there! Look at that! Of course, you want it

to stand up, looking very proud on your mantelpiece, so to do that,

grab a little bit of extra card from earlier.

I am just using some silver card, with a bit of double-sided tape.

Plonk that on the back, like so. Doesn't have to be too neat,

but leave a little space at the top for your Christmas message.

Think how cool you can make it.

You can put anything on there you want.

It's your surprise cracker card! We made loads earlier.

They really do look so cool. We have got one here of little Iggy's face!

She is wearing a little hat. We have got a Christmas wreath there.

Blue Peter ship. You can honestly do anything you want.

All the details and the templates you are going to need are on

the Blue Peter website...

I love this, you know, and I am not the only one. Check this out.

It's THE Christmas card that is taking the television world

by storm.

From everyone at Casualty, a merry Christmas and a happy New Year.

-BOTH: One, two, three!

-Whay! Look at that!

Thank you for this fantastic Christmas card you have made me.

-Does it do something?

-Yeah, we pull it.

-Ooh!

BOTH: Have a great Christmas.

Thank you, Blue Peter! You're fantastic!

Susanna Reid, of course it does something!

It's your surprise card. We want you to make one.

Send us anything you like of your Christmas card.

The address you need is...

I am going to go have a sit-down. Make your cards! Radzi...

I love it when something is really simple, yet awesome,

at the same time. Now, though, another Christmas tradition,

which began on Blue Peter over 50 years ago, is this -

the advent calendar. You came running, Linds.

-We love the advent calendar.

-We do!

-The special part of it is,

for the next four shows, we'll be lighting one of those candles,

to count down until our Christmas show on December 17th. We can't wait.

We really cannot wait. The candles here are battery-powered.

Can we ask for the lights just to be dimmed a tiny bit?

As I rotate this, you can see we've already got there one candle lit,

which means we are only three weeks away from the Christmas show

-and I cannot wait!

-I have got your present. Have you got mine?

-No.

You need to go shopping, Radz. Let's walk this way,

to the Big Badge Wall, covered in all of your brilliant post.

And it is looking very colourful this week. Sophie, who is 12, from Essex,

has done this. She has got a little Blue Peter Shelley there,

the badge and, of course, she has written us a little

Shelley the Tortoise poem. If I open it up, one line is,

"Shelley loves being with the BP Crew

"As there's always so much she can do."

Sophie, we love it. You're a genius. Thank you.

I also love what Ava from West Sussex has made. Look at this!

This me at the World Gymnastics Championships, doing a handstand,

with a big smile on my face. Why? Because I now love gymnastics.

-Ava, thank you so much.

-That was my favourite of your challenges.

-Really?

-Clemmy, who is 12, has sent this brilliant one in.

Have a look. It is little Barney, with his glasses on and his beard.

I love that. Holding his drone. It says, "Blink and you might miss it!"

-They were SO fast, these drones.

-Unbelievably quick.

-Amazing.

Thank you to every single one of you who made a piece of art that is on

this board here and to anyone who sent in post. Keep them coming in,

-with regards to the Christmas cards.

-If you do send something in,

remember, we need your full name, your address and we need your

date of birth. Otherwise, we can't give you a BP badge -

and you definitely want one. If you are between 6 and 15,

you can get your hands on one, because it is all about the badge.

It is also all about the Blue Peter website.

There is loads going on there. We have got the Blue Peter fan club,

which happens twice a week, on a Tuesday and on a Sunday.

There is also an exclusive clip, including a drawing made by

a Hollywood director, the man behind The Good Dinosaur,

who has drawn this picture of a dinosaur, with bits on it sent in

by you guys. So, well done for that. Jump online if you want to see that.

However, now it is time for me to refine my climbing skills,

to experience sea survival, because I am about to enter

one of THE most extreme working environments anywhere. Help.

There are over 6,000 wind turbines

in the UK, which help generate power for our homes.

But how much do we actually know about wind energy?

Well, to answer that, I will be going to the top of a turbine

in the sea, to find out how man can harness the power of the wind.

But before I can go near 130 metres of turbine, I need to undergo

some serious training.

I have come to this training centre, where you can learn

some of the skills you need for some of the most extreme

working environments in the world.

Because an emergency could occur while I am at sea or working

at heights, I need to prepare for the worst.

So, I will be taking on four stages of tough turbine training.

Stage one...

'OK, so I am in a pool. It is actually quite relaxing.

'All under the watchful gaze of Ken, my gentle sea survival instructor.'

Come on! Come on! Push it out! Come on!

Keep on going! Come on!

Come on, lads!

I have done a lot of courses in the army and, mainly, I find that

motivation is my biggest asset.

It's imminent!

'Sea survival just got serious. and the next part is even tougher.'

Because work on a wind turbine can be truly dangerous,

you don't know how or when you will have to get off that wind turbine.

So, if the worst comes to the worst, you might have to do what I am about

to do now, which is step off.

Look straight ahead. Step off.

'And Ken's punishing training just kept on coming!'

Come on! Push it out!

Come on! That fire is coming at you here!

Come on! Move it!

Come on, lads, push it out!

Stage two...

'If we need to jump into the sea, a life raft would be deployed.

'I need to be able to climb on top of it and flip it over,

'using just my own body weight.'

'Here goes.'

'Whoa! I did it!'

At sea, speed is vital to our survival, as we would be facing

freezing water temperatures.

'With the raft the right way up, the team and I need to get inside

'as quickly as possible.'

That was 50 seconds!

'Nice work, guys.'

Stage three...

'The most dangerous part of my adventure is transferring

'from the boat to the turbine.'

All that's between me and the sea is a steep - and I mean steep - ladder.

And so to help me get to grips with the climb

is Michael, my instructor.

Well, Michael, I am kitted out, ready and raring to go.

What exactly have I got on here?

First of all, you have your harness, to keep you safe.

And then you have your lanyards, two of them.

-What they'll do is catch you if you do fall.

-Very important.

With my harness in place, I attempt my first climb. But there are rules.

I have to keep three points of my body in constant contact with

-the ladder...

-Good.

-..as well as one of my hooks.

On top of this, my hook should be placed three rungs above me

on the ladder, and this takes practice.

That's done, that's done, now take off the...

-No, the rope!

-Great.

Tell you what, there's a lot to remember.

It is one thing doing it in here, a warm, comfortable environment,

-but actually, if it matters, would you panic?

-That's what this is for.

No panicking.

Stage four, the controlled descent.

In order to complete my training, I need to test my

head for heights as I'm lowered down this massive tower.

I am now 30 metres above the ground on a training tower.

Basically, this is going to simulate what would happen

if something were to go wrong on the actual wind turbine

and I would need to evacuate.

So for now, it's time for me to let go of this rope,

keep my fingers crossed and say, "Mum, I'm flying!"

Yes! Whoohoo!

Oh, yeah! Mum, I can fly!

Yeah.

There's a leap of faith at the very top

when you think, "I'm trusting the rope. All I've got is this rope."

And then you just enjoy it and you float down.

You feel like a superhero. I like training for the wind turbine.

Bring on the real thing.

Don't miss next week,

when I take you to one of the most extreme working environments

I have ever seen, and put my training to the test.

There are some really cool jobs,

and working on a wind turbine is one of them.

Now, though, from wind to rain.

It's time to welcome back to Blue Peter Mr Greg Foot!

APPLAUSE AND CHEERING

It's Greg. What have you got for us today? I'm so excited.

Right, I want to bring the weather from outdoors indoors. OK.

I want to make cloud and rain right here in the Blue Peter studio.

I definitely want to see that as well. What's this?

Let's start with the cloud. So I'm going to make you a little cloud

and then we're going to super-size it. First of all, question for you.

-What is a cloud made of?

-Easy, water.

-Good man. Yeah, water.

But the real question is how does that water clump together

into a cloud and how does it stay up there?

So all around us is air,

and that's made of a whole bunch of different gases.

You've got oxygen that you breathe in.

You've got carbon dioxide that you breathe out.

A whole host of others, including water, but as a gas.

-We call it water vapour.

-OK.

Now, as all that gas rises, that water vapour rises,

it cools down as it gets to the top of the atmosphere.

And when it cools down enough, it can turn from a gas to a liquid.

If you think about when you breathe on a really cold window, like that.

-Oh, condensation?

-Yeah. So the water vapour,

the gas in your breath, cools down into little droplets that you see.

It is called condensation. That's all a cloud is.

-Just condensed water vapour. Now, can you start pumping?

-Absolutely.

Some eye protection for you first.

-Remember, safety never takes a day off on Blue Peter.

-True that.

Right, 15 pumps, please. So what you're doing right now is

you're pumping air into the bottle.

And the air has got water vapour.

I will put a little bit of water in there as well.

So you're building up the pressure.

When the pressure is enough, I'm going to pop the top off.

The pressure is going to decrease, which actually cools

the whole thing down. So it's going to be like

what happens up in the atmosphere. It cools it down and hopefully,

we'll get a cloud. So it needs to actually have something to

grip hold of. Those water droplets need to grip onto something.

Up there in the sky, it could be salt from the sea,

it could be dust, it could be soot from a wildfire.

-I put a little bit of soot in here. Are you ready?

-Yes, I am.

Three, two, one!

-Yes!

-Yeah!

-See that cloud in there?

There's a cloud in the bottle.

There is probably millions of tiny little water droplets

-in there to make our cloud.

-That's crazy.

So I'm going to make a much bigger version of that to fill

the whole studio afterwards.

-The question, I guess, is how it actually stays up there.

-Yeah...

And it's because the droplets are so, so tiny.

They're surrounded by air,

they're light enough to float up there.

But once they start banging together and the cloud grows,

the droplets get so big that they can start to fall.

-And that of course is...

-Rain.

-Rain.

Question for you, Radzi from Blue Peter. What shape is a raindrop?

-That's easy. It's like a teardrop, so it looks a bit like that.

-Uh-uh!

I'm going to show you. Right, this is a raindrop levitation device.

-Yes!

-You're going to love this.

We obviously can't skydive next to a raindrop to see its shape.

So what this is going to do is air is going to rush up

and I'm going to try to keep a raindrop in place,

so the air is going to be rushing around it.

-It's the same as what happens as it falls.

-Wow.

-So, let's give this a go. My air is on.

-Yeah.

Now what I'm going to try to do is put a raindrop in there.

More air! There we go, there we go!

-Oh!

-Now, that's not bad.

-Very hard to do live.

-Absolutely.

-So I filmed it in slow motion earlier in the rehearsal.

-Amazing!

Have a look and tell me what the shape is. Watch this.

This is amazing. Watch.

-Out it comes.

-It's flat!

-Yes.

-It's really flat.

-Look underneath. How gorgeous is that?

This, Radz, is my favourite fact.

You'd think a raindrop is round. Spherical, like a ball.

When they are really, really small, they are that shape.

But when they get bigger, they fall,

and they fall fast, like 15-20 miles per hour.

They're falling and all that air is hitting them underneath.

And it squashes the bottom of the raindrop

and you get that beautiful burger bun shape.

Why you said teardrop is you always see it running down a window.

Or dripping out of the tap.

What that does is it pulls some of it behind it

and it kind of creates this tail. There you go.

-There you go. Is it all a big myth?

-Yeah.

Now, Greg, I hate to hurry you but I want to see the big one!

Let's do it. Come over here, my friend.

Right, what you're going to need is to put on this poncho.

Because this could get a little bit damp.

Remember, a cloud is just trillions of drops of water vapour

-that have condensed, that have cooled down into water droplets.

-OK.

So, Tom, can you bring all my ingredients for a cloud, please?

-Tom, come out, my friend.

-Thanks, Tom.

-What's in this?

In this is everything you need to make a cloud. Thanks, buddy.

So what we're going to do is we have made ourselves nice and safe.

Now, we need something very, very cold, because when it's up there

in the cloud, that's what causes the cloud to condense, to cool down.

So what I've got here is liquid nitrogen.

Whilst you're doing that, I do have to say, please,

for goodness' sake, do not try this at home. That's why we've got masks.

-Greg knows exactly what he's doing.

-We've got some liquid nitrogen.

Now I've also got some hot water.

The hot water is going to go into my liquid nitrogen.

It's going to turn it from a liquid into a gas.

Cold gas up in the air, that's going to cool down the water vapour

-in the sky and hopefully make a cloud.

-I want to see this!

-Are we ready for this? Everyone on the floor happy?

-Yeah!

OK, so in three, two, one!

ALL: Whoa! Wahey!

-That is amazing. We've just made a cloud on Blue Peter, Mum.

-Yeah!

Can we see that again? That's it in slow motion. Look at that!

-Oh, that looks good.

-That's nice!

-There it is. Our cloud.

All those water droplets in the air. Yes!

Greg, I love when you come on, because we learn so much.

-But come over this way.

-This is the science I love!

Radzi absolutely loves this. At the start of the show,

we asked you lot at home to get in touch with us and let us know

if anything could rain out of the sky, what would it be and why?

-There you go, Radz. Oh, you're quite wet.

-I'm very wet. I'm in the cloud!

Navy Blue Pickle Star Fish - great name -

says it should rain massive, buttery crumpets. I like that.

Now, I like Gold Robo-Bluebell Star, because they say sweets,

dogs, cats, horses, unicorns, hamsters and crowns. You're not...

-You're hedging your bets. I love it.

-This is great.

Someone's gone for a food theme.

Indigo Singing Orca has gone for spaghetti bolognese

-and garlic bread.

-Such a good meal, though. Amethyst Vanilla...

I want to read you a really, really good one. This is for you.

Crimson Flute Canary says magical homework pens that just do

-all your homework for you.

-Genius.

-Love it. Love it.

Now, Clarice Cheeky Swan says, "I would make it rain computers

-"because I can use them when I'm not allowed." I like it.

-Cheeky.

Here's another animal one. Amethyst Vanilla Chicken

wants it to rain chimpanzees,

-orang-utans and gibbons.

-Big monkey fan. I like that.

I kind of agree with this one.

Lime Smiling Conker says, "I would make it..."

There's so much cloud over there still!

"I would make it rain dogs, as I really like dogs,

"and then I could have loads." I like that.

-Imagine loads of Iggies just coming out the sky.

-Pretty sweet.

Now, time for one more.

"I would rain genies."

So they have found a flaw in the question and exploited it.

-Good work.

-As you know, if you have been on the Blue Peter fanclub page,

we have been playing presenter bingo and the phrase today was,

"It's all about the badge."

And the person who got that was, I can reveal...

Quartz Brainy Kid.

So, Quartz Brainy Kid, well done to you. Good job.

That's all that we've got time for today,

but make sure that you are watching next week.

There is loads happening, including Nathan Sykes, who is going to be here

to perform his brand-new single, and trust me, it is a beautiful one.

Now, my training is done, but it's now time for me

to climb up a wind turbine and see just how it works.

Make sure you watch that.

And this is a bit of a tongue twister,

but we're looking at the amazing tech behind the puppet penguins

in Mr Popper's Penguin Musical.

Alliteration! Nailed it, boom!

-See you next week. Bye!

-Bye-bye!
