Epic Science and ChrisMD Blue Peter

Coming up on today's show, we launch our brand-new

Sport Relief challenge, which we want you to get involved in.

And it's all about getting your feet moving.

Which is why we're joined by the super sporty Ben Cajee

who's going to help us. Get your feet up, Ben.

Whoo!

CHEERING

Whoa!

CHEERING AND APPLAUSE

Hello, you're watching live Blue Peter.

And look who my glamorous co-presenter is.

It's the one, the only Ben Cajee from Match Of The Day Kickabout.

-Thank you so much, Linds.

-I'm excited.

-Look how excited they are.

-That's loud.

-The crowd love it.

-Are you excited to be here?

-So excited to be here.

Especially because we are launching the Blue Peter

and Match Of The Day Kickabout Sport Relief challenge.

It's going to be good but whoa, whoa, whoa,

not yet, guys. Later in the show.

-First, it's time to focus on this little sporty ledge.

-There she is.

Shelley will be hiding somewhere in the show. I love her hat.

I'm really into it, it's adorable.

If you see her anywhere, get onto Fan Club Live,

-let us know where she is.

-I love Spot Shelley. What a great game.

Radzi went to visit a science experiment, which is 16 miles long.

I don't believe you! As well as that on the show, we're going to have

the amazing Jess Robinson doing some fantastic impressions.

-She's very good.

-She is. First, though, we are going to be meeting

a man who has over 620 million views online.

-Pardon?

-I said that right.

620 million. He's played football with superstars,

Premier League superstars like Alexis Sanchez and Kevin de Bruyne

and he has even filmed with Real Madrid icon

Cristiano Ronaldo, it's ChrisMD.

-APPLAUSE AND CHEERING

-Yes, Chris.

-How are you?

-I'm well. How are you?

-not bad at all, thank you.

Great to have you here. Now, I know you have some incredible online

videos but you also play football for a club, as well, don't you?

Yes, I play for St John's, back in Jersey.

Jersey is a lovely place to play football.

I've seen your knuckleball

free kicks where you hit the valve of the ball

and they bend and go all crazy, hopefully into the top corner,

just like... Ooh, nearly.

Have you scored any of those in big games?

I've tried a few. Let's leave it there.

But you've played in some very big stadiums, haven't you?

Yes, I've played at Wembley three times.

-Three times!

-The Nou Camp.

Also St Mary's, Charlton, I've managed to flick the ball over

Robert Pires and Jamie Carragher at one point. Name-drop that one.

Good name-drop. Very impressive. And so is this.

-Yes.

-It is your book. Tell us about that.

-It is.

It's my debut book and it's all about Sunday league football,

my videos, and my life, and hopefully with all the humour

and stuff that's in my videos.

There are loads of anecdotes in here and different stories,

-but one is pretty unusual.

-It is.

At the start of a Sunday league game,

we had a brief little pause while our left back pointed out there was

a big hefty pile of dog poo on the side of the pitch.

That's nice(!) Hopefully, that won't

-happen today on the Sport Relief challenge.

-Hopefully, yeah.

-But you'll stick around for that.

-I will.

-And you'll be

around for Fan Club Live as well. So, get your questions in.

We want them because you're going to answer anything that comes in.

-Anything.

-Fantastic, yeah.

-ChrisMD is here, I'm quite star struck.

I've got a question for you, Ben. Would you rather play

football at Wembley or win a Blue Peter Book Award?

Both. You can't pick between those, can you?

You were meant to pick. Maybe this will help. Have a look at the VT.

Who better to give us the lowdown on the three books with facts

shortlisted for this year's prize than these guys?

Some of the biggest fact fans we could find. And this lot are keen.

Could we do Beyond The Sky, please?

Yeah. All right, then.

Beyond The Sky, You And The Universe

is written by Dara O Briain and illustrated by Dan Bramall.

Hop on board the funniest space flight ever for an astonishing

and incredible journey through the solar system.

This book reveals some of the fascinating secrets of space,

its exploration, and the science behind it all.

My favourite part from the book is when they showed us

how big the black holes were cos they were really big.

He put fun facts into it.

I really like space, personally, and I know quite a lot about it,

and a few of the facts really amazed me.

If you cry in space, your tears won't fall down.

It was like the book was talking to you

so when you were reading it,

it felt like somebody was actually there.

I love the humour that was put into the pictures.

It made you want to keep reading and find out what would happen next.

And speaking of next, it's Corpse Talk: Ground-breaking Scientists

by Adam and Lisa Murphy.

Packed with incredible interviews

with history's most awesome scientists,

Corpse Talk is a hilarious comic book that brings the dead to life.

Get ready to dig the dirt and uncover more on history's

ground-breaking scientists.

I liked it because it was like an interview between the two people.

People who were dead would come to life and be interviewed.

It was like a chat show, and it was really funny.

I definitely like the way it was set out, like a cartoon

because you could feel like it was being animated.

And there was a much funner way of learning about the world's

smartest scientists.

Corpse Talk tells about their life and their career

so it might pick up you, and then say, oh, I want to be a scientist.

I was really into it because of the pictures.

And I loved it.

Finally, it is Real-Life Mysteries by Susan Martineau,

illustrate by Vicky Barker.

Delve into some of the most intriguing mysteries to ever exist.

Heard of Shackleton's ghostly companion?

Or the Loch Ness Monster and friends?

Examine the mysterious cases

and perhaps you'll be the one to cover the truth.

Oh, I really enjoyed this.

It was just the front cover that was like, oh, wow.

It's quite fascinating to try and work it out for yourself.

And it's giving you things to think about,

like UFOs, aliens, ghosts.

The one about UFOs, I found that actually quite scary.

I love the evidence, and the theories, and all the information

that was packed into such a small book.

Who knows who will win this year's Blue Peter Book Award.

But what I do know is that this lot are happy readers,

and that's a fact.

Love that. It's a strong category.

Now, time for something a little bit different.

You might recognise the next guest from Britain's Got Talent.

She's here to impress with her incredible voice.

Please give it up for Jess Robinson.

CHEERING AND APPLAUSE

Wow, Jess, you're amazing!

-Oh, thank you.

-They were uncanny.

I feel like they were all in the studio with us.

-Yes, they are.

-You've earnt that BP badge.

When did you realise you could do that?

Oh, probably when I was about nine years old,

and I used to take the mickey out of my mum,

-who sounds like this.

-I'll take your word for it.

-She sounds like this,

She goes, "Jessie, I don't sound like that," but she does.

-And I used to...

-That's quite a voice.

-It is.

-Quite terrifying.

-I hope she's watching.

-Me too.

So, you're a voice-over artist,

you got to the semifinals of Britain's Got Talent,

there's no stopping you. You're going on a tour soon as well?

I am. I'm going on a tour, it starts on 1st March.

And it's around the whole of the UK.

It's called Here Come The Girls, and it's full of impressions,

and comedy, and musical mash-ups and stuff that makes everybody happy.

Well, listen, we love you, we think you are amazing.

We've got something quite special planned. We're going to put your

-impressions to the test.

-OK.

-Are you up for this?

-Yes.

OK, this is going to be amazing. Cue the cheesy game show music.

There it is. Let's walk this way, in a cheesy way, I guess.

OK, so here we've got the Wheel of Destiny, and on the Wheel

of Destiny, you can see there's loads of different nursery rhymes.

Six, to be precise. And, then, look,

-we've got some amazing BP super fans.

-Hi!

Once we've chosen a nursery rhyme,

-they're going to choose what style you sing that nursery rhyme in.

-OK.

So, we're going to get some quite funny mash-ups here.

The crew are very excited. Because you are so good at this.

-Shall we spin the wheel?

-Yes.

-You've brought Kirsty along as well.

I've got my wonderful friend Kirsty to help me on the piano.

-Hello, Kirsty, welcome to BP. Right, let's spin the wheel.

-OK.

-Ooh, it's a slow one.

-That's very slow.

-It's Wheels on the Bus.

And which super fan are we going for?

-I'd love to go for Adenay.

-Adenay, what do you want?

# Uh-uh-uh uh-uh Uh-uh-uh uh-uh hey! #

-Right, I love her.

-Hey, single ladies!

I bet you can't do a nursery rhyme like Beyonce would.

-I'm sorry.

-I love that.

-I love her.

-I love her.

So we have got Wheels On The Bus by Beyonce.

Go on.

-SHE SINGS LIKE BEYONCE:

-# Oh, the wheels on the bus

# Go round and round

# Round and round Round and round

# Oh, the wheels on the bus Go round and round

# All day long. #

Fair play!

As a Beyonce superfan, that was great.

Next nursery rhyme, we're going for...

It's Baa Baa Black Sheep.

-Classic.

-And which superfan are we going for?

-Rosie, please.

-It's got to be Rosie.

Go on, Rosie.

# One last time

# I bet you can't

# Do Ariana Grande. #

Right. Rosie, those moves are legendary.

Can you do Ariana Grande doing Baa Baa Black Sheep?

Yes! The thing with Ariana Grande

-is you never understand what she's saying.

-No.

-BREATHILY:

-# Baa Baa Black Sheep Have you any wool?

# Yes, sir, yes, sir Three bags full

# Oh, one for my ma-a-aster!

# And one for the dame

-INDISTINCTLY:

-# And the lil' boy who lives down the lane. #

I want to play this all day. Let's do another spin.

-OK.

-We've gone to...

-It's Old MacDonald Had A Farm.

-Whoa!

Classic! Who are we going to go for?

-Who's next?

-Let's go for Matt and Chloe.

OK, Matt and Chloe, what do you want?

# Hello

-# It's us... #

-LAUGHTER

# We were wondering if you could do it

# In the style of Adele. #

-Right.

-I bet you can't do it!

I'm obsessed with them. They have so many Blue Peter badges.

-They're after my job.

-In the style of Adele. Off you go.

OK. Gosh.

-DEEP AND SOULFUL VOICE:

-# Old MacDonald had a farm

# E-I-E-I-O

# And on the farm he had a co-o-o-ow

-# E-I-E-I-O... #

-SHE LAUGHS

# With a moo-moo here and a moo-moo the-e-e-e-e-e-ere

# A moo-moo everywhe-e-e-oo-ee-oo-ere. #

SHE LAUGHS

That was some amazing mooing.

APPLAUSE That was so good!

I want to play this game all day. We have run out of time,

so let's go over to the big badge. Bring your impressions with you.

That was so good, I wish I could sing like that.

We've been having a look at the Big Badge wall.

Chris, what have you spotted?

I have spotted this boot by Bobby. He's got his Blue Peter badge.

-Smashing boots.

-Yeah, nice colours.

Bobby, if you like colouring in boots,

you're going to love our next Sport Relief challenge!

Jess, what have you spotted?

I love Shelley here.

-She is made by Calila and look, you can dress her up!

-This is amazing!

And Calila has obviously been inspired by the Winter Olympics,

because you've got this lovely medal here. I love it.

Oh, like Lizzy Yarnold. That's so good, thank you.

I tell you something else which is great, which is this.

Dylan, you've earned your blue badge.

You were inspired by the experiment last week.

-And there is Steve.

-Yeah, there's Steve Backshall!

If you're wondering how he's getting on,

he hasn't started his climb yet, but he will be soon, and all the updates

will be on the CBBC website. So make sure you check those out.

That's right, and keep your post coming into the usual address,

because we absolutely love to see it.

And you can earn a badge just like this one here.

Once you've done that... I like this part.

..you can apply for one of these. Look at that!

ALL: Whoo!

It's the diamond badge!

Just head to the website for all of the details, but remember,

they are only available during BP's big birthday year!

-That's right. Hashtag Limited Edish.

-Oh, yeah.

Now, remember, a BP badge can get you into over 200 attractions

across the UK. ..Maybe do it as Jessie J?

# F-f-f-f-f-free-ee-ee! #

As Mary Poppins?

-PRIMLY:

-# For free-ee-ee! #

-As me?

-# For FREE! #

Yeah, that was good.

-Fair play.

-Linz, can I do an impression?

-Yeah, go on.

-Check this out.

THEY CHEER

It is, of course, Radzi!

-Not quite as good as the real thing.

-True.

Speaking of the little devil Radz,

before he went to the Winter Olympics, he went to see science

on an epic scale. This is so cool. Check it out.

Our universe.

It's incredible.

Full of natural wonders that have fascinated us for centuries.

Like my hair.

But how much do we actually know about how it all started?

The world?

The galaxy! The universe.

Many scientists believe the universe began with the Big Bang,

a massive explosion nearly 14 billion years ago.

And that by recreating the Big Bang,

they will find out more about how the universe began.

So how do you recreate the Big Bang?

OK.

Bang!

Nah.

BANG!

Still not enough.

I know. Ahem!

BA-A-A-A-ANG!

No.

I'm going to need something a lot bigger.

Thankfully then, the European Organisation for Nuclear Research

built the world's biggest machine to do just that.

It's called the Large Hadron Collider, and is run by a team

of thousands of technicians, engineers and scientists.

Scientists like Sudan.

So, the Large Hadron Collider is a 27km particle accelerator

built 100 metres under the ground of the French and Swiss countryside.

This is the largest science experiment ever.

And I've come to Switzerland to pay it a visit.

And here it is, the Large Hadron Collider, and this thing does...

..OK, I don't really know. Can I have some help, please?

The Large Hadron Collider

accelerates particles at very high speeds,

close to the speed of light, in fact, and then bashes them together

really, really fast and then we see what happens from those collisions.

So, the idea is that, by crashing particles into each other,

this machine will recreate lots of tiny big bangs,

which can be studied.

And I've been allowed access to find out more about how it works.

When I was in school, I loved it in science when they made it simple,

so with that in mind, what actually is a particle?

Everything around us - your hat, even us - if we break it down

into the smallest possible bit, that is what we call a particle.

Just to give you an idea of how small that really is,

-if you take a grain of sand...

-Yes.

-..which you know is very small...

-Yeah.

-..there are 100 million million million particles in it.

So that's 100 with 18 zeros of particles.

In a grain of sand.

That is so small.

To study something so small,

you need some pretty big scientific equipment.

And when I say big, I mean the size of the three double-decker buses,

and that's the first stop on my tour.

Sudan, this is the biggest science experiment

I have ever seen in my entire life.

OK. So I know particles are really small.

So why is this so big?

This piece of equipment is like a camera, a digital camera.

You can imagine cameras, you know,

you sometimes hear 10 megapixels, 20 megapixels.

This is a 100 million pixel camera,

taking photos 40 million times a second.

Right now, this massive experiment is closed for maintenance,

so I'm going to areas that few people are ever allowed to visit.

We are 100 metres underground,

and the scale of this place is off the charts.

So the guys here don't always walk to get around,

they have come up with a rather genius method,

not just any old push-bike - oh, no, no, no. What is this, Sam?

Hey, Radzi! This is an electric bike that I use to get around,

because there's such long distances between points in the LHC.

It looks like an awful lot of fun.

And what about yourself, what's your job?

I'm an engineer here. It's not just physicists who work at CERN,

there are many, many different professions here.

Engineers look after, fix,

maintain and design new parts of the LHC.

Actually, that variety is brilliant for you at home,

because if you would one day like to work here, you could.

Well, Sam, I won't hold you up, off you go on your awesome bike.

See you later!

The Large Hadron Collider is so big, it spreads beneath two countries.

But why is it so big?

And why is it a circle?

Well, scientist Alex is going to demonstrate.

That means we need our safety specs.

Absolutely.

We are using liquid nitrogen to cool special magnets.

This changes how they work and keeps our Blue Peter badge

on the circular track.

-And this is a small circle.

-Yep.

-I know the Large Hadron Collider is a really big circle.

-Mm-hm.

Is it similar?

It's the same general idea

of trying to get the particles to go round on themselves,

so that we don't have to build a straight line

that just wouldn't fit on planet Earth.

So the magnets help bend it and keep it inside that circle.

That's exactly right.

The particles need to travel at nearly the speed of light,

and the circle means they can spin round and round,

getting faster and faster.

-It's been an absolute pleasure.

-Me too.

Do you know what? Science is awesome.

The people working here are trying to make discoveries

that could change the way we see the universe,

and it's been a privilege to meet them.

You are clearly very passionate. How much do you enjoy your job?

I absolutely love my job, Radz.

I am here in the world's largest scientific laboratory,

really pushing boundaries of knowledge,

trying to find out questions that humanity has been seeking

since the dawn of time, I would say.

Who knows what they and this mighty machine

might discover in the future?

This place has genuinely blown my mind, and the reason for that

is because one of life's biggest questions

is how life itself started, and we are finding out that answer

because of what happens inside there,

which is why we have left them with a Blue Peter plaque.

This plaque will be kept here

to celebrate Blue Peter's 60th birthday.

What a place and what an unforgettable day.

I love when Radzi wears a hard hat. That's making me miss him.

It would take the average person

five hours to walk around that collider. It's big.

It certainly is.

That's 16½ miles or, get this, 33,500 steps.

Whoa!

Yeah, I know. It brings us nicely on to our 2018 Sport Relief challenge,

because Blue Peter and Match Of The Day: Kickabout

-are coming together...

-We are merging.

-We are - merging...

..to collect your steps for Sport Relief.

It's got a name, we're calling this the Mega Mileathon,

and we're going to try and collect...are you ready for it?

-Go on.

-A million steps!

-Yes, that's right.

-That's a lot.

That's a lot of steps, so obviously,

we need your help. We need you to get involved.

The way you can do that is get online. Head to the website...

-And then download a trainer. You have a few to choose from.

-You do.

You can even pick this one. It's like a football boot.

I coloured this in this morning.

I went for West Ham colours. It's not really claret and blue though,

it's more like pink and aqua.

Yes, it's jazzy, and I like it.

-But you can decorate...

-How many miles are you doing?

50. I've gone for 50. Yeah, I know, it was big.

You can decorate your boot or trainer

in any way that you like, make it unique.

Now, speaking of how you're going to get these miles, the steps,

-you don't have to run. You can walk, you can cycle, you can swim.

-Scoot.

You can wheel, you can scoot, you can, I don't know,

salsa and shake your way around. It doesn't matter.

-I like that.

-As long as you're not in the car or on the bus,

because that obviously doesn't count as miles.

We're going to convert those steps into an average number of miles

and add it to this, the Sport Relief Totaliser!

-Oh, yeah!

-It's glorious!

-Now, Linz...

-Yes.

-There are some big numbers on here.

-Yeah...

-It's fair to say we're going to need your help.

You need to send everything into us by 21st March.

-Get involved.

-Do get involved.

And that's not it, Radzi and I are getting involved as well.

We're doing a Mega Mileathon challenge between us

with some BP fans, which is going to be tough.

And if you want to see how we get on, check that out on 27th March.

It's our Sport Relief show, it's going to be great.

-And you're converting miles into steps.

-It's all going to go on here.

It's very, very cool.

-I wish that I could add some steps right now.

-Yeah.

It's a good job we can play a game, because welcome back, ChrisMD!

-Here he is.

-APPLAUSE

Right, Chris, we need your help now.

We reckon you're pretty good with the football, pretty good knowledge,

so it's time to play Blue Peter Target Tekkers!

-Here we go.

-Let's do it.

Dear me, had to relocate quickly there.

Chris, are you ready?

This is going to be a fun game.

-You look ready.

-I might need a football.

Yeah, you grab a football.

While you do that, let me explain how it works,

because on this net over here, we've given you six targets.

Each target has a different word on it.

I'm going to ask you some questions, not too hard,

and you have got to smash the ball into the net at the right answer.

-Think that sounds all right?

-Yeah, that sounds very easy.

Well, let's look at this guy,

because my glamorous assistant Ben is on the treadmill.

-I've started.

-And you're trying to get those steps up,

so how many are you on at the moment?

-Not very many.

-So basically, Chris, we need your help,

because for every one that you get right,

we're going to be cranking up the speed on the treadmill

and Ben will have to run really fast to add his steps to the totaliser.

Have I been clear? I don't even know what I'm saying.

Run like the wind, basically.

-When you hear this whistle...

-On you go.

WHISTLE BLOWS

..then it's all over and time is up. So shall we get started?

Yeah. I can't wait to see him running in those jeans.

We're live, you're going to be good.

OK, ready? True or false, Qatar is hosting the 2018 Fifa World Cup.

-Oh, it's no, it's... It's false.

-Go on, Chris.

He has gone with his heart. He nearly got it.

Who won the 2017 FA Cup Final?

-2017, that's going to be...

-Come on, Chris.

-Oh, no!

-He's missed Arsenal!

Who will win the 2018 FA Cup Final?

-Not Arsenal!

-Say it again, sorry?

-Who will win it?

-Not Arsenal, you're out.

-Definitely Arsenal.

OK, he thinks Arsenal, but they are out.

I will go faster anyway.

What programme are you appearing on right now? ... Peter.

It's definitely Blue.

Yay! Get that speed up!

True or false, Stoke and former England striker Peter Crouch

is six foot nine inches tall.

I think that's going to be true. Arsenal.

It's false, but you nearly got it, so turn the speed up anyway.

WHISTLE BLOWS

Time is up.

I'm getting there.

That was stressful, to say the least.

Ben, how many steps are we on?

I'm on about a tenth of a mile, which is about 200 steps, maybe 250.

-It's not enough.

-OK, good maths.

-Thank you.

-Not quite enough to get

us to our first light there, which is 100,000, which is why

it's so important that you lot at home get involved.

Please, all the details that you need...

-I'm so sorry that you having to do this.

-I'm quite enjoying it.

..on the Blue Peter website.

While you're on the website, check this out.

-Go, keep going.

-Thank you, thanks.

If you were a vegetable...

Not a good start.

You'd be a cute-cumber.

-Wow!

-Aw...

What's inside the hat?

HE BEATBOXES

You can create your own story using random words.

There you go. As you would have seen there,

the seven days of stories gives you basically seven tips

so that you can hopefully write your very own little story,

which is great, so head online.

That's almost it for today's show.

I'm still a bit out of breath. I need to get fit!

We need to do Spot Shelley. Where was she hiding?

She was hiding in the nursery rhyme wheel.

-Yes.

-Classic.

And Rufus Pup was the first person to spot her.

Great name as well, Rufus Pup.

Well done! That's nearly it for this week's show.

Make sure that you are watching next week. There's loads going on.

It's going to be good, isn't it?

-It's going to be very good.

-Chris is on Fan Club Live, by the way,

after the show, so also head there.

Because it's going to be exciting. Can they ask you anything?

-Anything.

-Big questions.

Like who do you support? We didn't ask that.

We haven't got time! Ask it online!

It's the BP Book Awards next week, isn't it?

The BP book awards. It's going to be great.

You get to choose who Lindsey and Radzi dress up as.

Now, you might choose The Twits. You can have Alice and the Mad Hatter.

Harry Potter and Hermione Granger.

And you've got until 12pm

on Wednesday, 28th February...

I've remembered that. ..to cast your vote.

So do it, get involved. I am going to vote.

-You are out of breath. You have done such a good job today.

-Thank you.

The reason I was speeding you up earlier

is because we needed to leave time for this.

We're going to give you,

because this is your second appearance on Blue Peter,

you've hosted the show, it's your very own silver Blue Peter badge.

So there you go, Ben.

I'm going to give you a hug. Thank you so much.

-You've been awesome!

-I'm made up.

Yeah? Happy? What's going to be on Kickabout?

Alex Scott is hosting the show, there's going to be FA Cup goals,

and Jordan Pickford answers your questions.

He plays for England and Everton,

so you can get involved with that on Saturday.

As well as that, I'm so excited because Radzi is back!

Thank you so much to Chris and Jess. We'll see you next week.

-Get onto Fan Club Live now!

-Do it.

-Well done on the badge.

-Thank you.

-See you!

-Bye!
