Hello there. I am just ironing my spare lab coat ready for tomorrow.

Look at all these wrinkles. And crinkles.

BEEPING

I hear a beep, I see a flash, I wonder what they're going to ask.

-Hi, Nina.

-Hi, guys.

We've got a question for you.

Why is Grandpa's face wrinkly?

That is a great question! Why is Grandpa's face wrinkly?

Bring your grandpa down to my lab and we will investigate!

See you soon, Nina! Bye.

Bye!

I need some help to answer this one and I know just who to ask.

OK, Neurons, time to get to work.

Neurons to the ready, Nina.

OK, today's question is why is Grandpa's face wrinkly?

Which neuron do you think would be best to help us find the answer?

-Me!

-Me!

-Me!

Will it be fabulous Felix?

I can help so very much if you need a sense of touch.

-Will it be beautiful Belle?

-I send messages to brain from ear.

If there is a sound, I will help you hear.

Will it be lovely, Luke?

For looking and seeing, day or night,

I'll help you with your sense of sight.

-Will it be awesome Ollie?

-If it's pongy or whiffy

but you can't tell, my messages help your sense of smell.

-Or will it be Baby Bud?

-Sour, salty, bitter or sweet.

I am your taste buddy whenever you eat!

-It is Luke.

-Yes!

CHANTING Go, Luke!

Cool, Nina. I'll be looking out to help you.

Today's question is why Grandpa's face wrinkly?

Because wrinkles are something we see,

our super sight neuron Luke will be helping us today.

I need to get the lab ready before the experimenters arrive.

Jodie likes guinea pigs. Chloe likes riding ponies.

Grandpa Jim loves hillwalking. They all want to know

why Grandpa's face is wrinkly. So today, for one day only,

Jodie, Chloe and Grandpa Jim become the experimenters!

-Hi, guys!

-Hi, Nina.

-Hello, Grandpa Jim. Welcome to my lab, come in.

Now, your question is why is Grandpa's face wrinkly?

Which is a great question, but why do you want to know?

-We love our grandpa's face.

-And we want to know why it's wrinkly.

Well, your grandpa does have a lovely face.

-Thank you for being part of our experiment.

-You're welcome, Nina.

We are going to have so much fun!

Let's start by using our senses.

Woo-hoo. A senses experiment! We are ready, Nina.

You say that your grandpa's face has wrinkles, but where are they?

Try using your magnifying glasses and have a closer look.

-Where can you see wrinkles?

-On his eyes and forehead.

-Have you always had wrinkles in those places?

-No, Nina.

-Here is a photograph of me as a boy.

-What a cute photograph!

-What do you notice about him?

-He has no wrinkles in the picture.

That's right. When he was a young boy,

your grandpa's skin was smooth, just like yours.

But now he's older, he has a few wrinkles.

Why has Grandpa's Jim's skin changed? Let's go over here.

We are going to pretend this material is our skin.

We will take a corner and pull.

What happens to the size of the material when we stretch it?

-It gets bigger.

-Yes, it gets bigger.

What happens when we stop pulling?

-It goes small.

-When we stretch it, the material gets bigger.

And when we stop stretching, it gets smaller.

That's what happens with our skin.

Let's try something else. Everyone pop your hands on the worktop.

-What do you notice about each other's hands?

-Grandpa's are big.

-And they're wrinkly.

-Yes, your skin looks smooth

because it is stretched tightly.

On your grandpa's hand, the skin is not stretched so tightly.

Very, very gently, pinch the skin on the back of your hand.

Be gentle. Pinching can feel a little sore.

Now let go. What happened to the skin?

-It pinged back.

-That's right.

In science, we say that skin is elastic.

Elastic means that, when something stretches,

it goes back to how it was before. But why is it so important

that our brilliant bodies have stretchy, elastic skin?

It is time for another experiment.

I am hoping you can face getting a special treat. Let's go!

I can't wait to see where we will end up today.

Nina said she hoped they could face a special treat.

-Maybe it's an ice cream shop.

-Yes!

I get the feeling they won't be eating ice cream.

Our senses experiment showed us that our skin is stretchy and elastic.

But to understand why, we need to find out what would happen

if our skin was not stretchy.

This is Louise. She's a beauty therapist.

She'll put some special stuff on our faces.

Some people do this to help look after their skin.

We're doing it as an experiment.

Try touching some of the special stuff

and tell me what it feels like.

It's so soft, it's squidgy.

Yes, it's soft and squidgy now, but when it's on our faces,

it will soon go hard and set - a bit like a mask.

-Louise, why don't you start with Jodie?

-OK, Nina.

I've given Grandpa Jim some cards with faces on them.

Once our masks have set hard, he's going to show us a card

and you're going to try to pull that face.

Then Grandpa Jim will guess what it is.

SHE TRIES TO SPEAK

Hee-hee-hee! Nina can't open her mouth properly!

NINA TRIES TO SPEAK AGAIN

Nina's asking them to pull that face!

What a strange feeling. Nina can hardly move her face.

I think that might be her angry face.

I hope Grandpa can guess it right this time!

Those look like they may be happy faces.

No, that was an angry face!

So, how did your faces feel under the masks?

It felt strange because we could hardly move our faces.

-How was it for you, Grandpa Jim?

-It was hard to make out the expressions

-or what you were saying, cos you couldn't move your faces.

-Yes!

Why do you think it's important for the skin in our faces to stretch?

So we can move our mouths to talk.

And to smile and make faces.

That's right, we need the skin in our faces to be elastic

so we can smile... and frown...and talk!

And the rest of our body needs stretchy skin too

so we can stretch and move our bodies.

So, we know a lot more about skin now, but we still don't know why

Grandpa Jim's face is wrinkly!

-I think we need to go back to the lab for one final experiment.

-Yay!

OK, in front here, we all have a beach ball,

and we're going to pretend that each beach ball

is a person's head.

First, we need to draw a face on these balls.

Go for it!

I've given mine a big frown!

Nice work everyone!

Now I'd like you to give your beach ball's face a little squeeze,

and tell me how that feels.

Smooth and firm.

Yeah. Now let's feel the skin on our face very gently,

-and tell me how that feels.

-Nice and smooth.

So, the beach balls and our face feel and look quite similar.

They're plump and firm and smooth.

The ball's like that because it's got lots of air inside,

but your skin's like that because of a special substance called collagen.

Collagen is one of the building blocks of the body,

and it's collagen and other things in the skin

that keep the skin feeling smooth, stretch and elastic.

When we're young,

we have lots of collagen in our skin, but as we get older,

our body makes less collagen,

and our skin changes. So now,

I'd like you to release a bit of air from your beach ball.

AIR HISSES

How do the beach balls look and feel now?

Soft and baggy.

Feels baggy and wrinkly. Just like Grandpa's face!

-NINA LAUGHS

-Can you two please face each other,

and give each other a big smile?

What can you see happening to the skin around your eyes?

-It's getting a bit wrinkly.

-Yeah? Now see if you can make

a big frown like I drew on my beach ball.

Now straight faces again...

What happened to the skin in between your eyes?

It went wrinkly, and after,

when we did the straight face, it went all smooth.

That's right!

But as our brilliant bodies get older,

our skin stops being so good at smoothing back out again,

after being crinkled up by frowning or smiling and laughing.

So we get wrinkles in the places that were crinkled up.

Your question was, why is Grandpa's face wrinkly?

I think we've answered it.

We found out that when we're young,

our skin is plump and stretchy and elastic,

which is great for allowing our bodies to move,

and our faces to talk and smile.

As our brilliant bodies get older,

they make less of a special substance called collagen.

This means that when we smile or frown, the crinkles on our face

don't smooth back out again,

and lines are left called wrinkles.

This is a natural part of growing older,

so next time you see someone with wrinkles around their mouth and eyes

you'll know they've done lots of laughing and smiling.

-Is that right, Grandpa Jim?

-Absolutely right, Nina.

-I hope that's answered your question.

-BOTH: Thanks, Nina! Bye!

Bye!

It's been a marvellous day.

What a strange sensation when Nina wore that hard mask.

Ah, it's been such a great day, man!

Watching the beach ball faces go from smooth to wrinkly.

I really enjoyed myself today.

They had so much fun making their skin crinkly

and smooth again.

And remember, everyone's body is different but they're all brilliant.

See you again soon! Bye!

ALL: Bye!
