Oh, hello!

I'm cleaning up after an experiment.

Do you like my fancy gloves?

My fingers like to be well-dressed when washing up.

And my little rubber friends keep my hands dry.

-BEEPING

-Oh!

I hear a beep, I see a flash.

I wonder what they're going to ask?

-CHILDREN: Hi, Nina!

-Hi, guys!

-We've got a question for you.

-Why do our fingers go wrinkly in the bath?

That's a great question! Why do our fingers go wrinkly in the bath?

That happens to me too, but my fingers and toes go wrinkly.

Why don't you come down to my lab and we'll investigate?

CHILDREN: See you soon, Nina! Bye!

Bye!

Well, I'm going to need help to answer this one

and I know just who to ask.

OK, Neurons, time to get to work!

-ALL:

-Neurons at the ready, Nina.

OK. Today's question is, why do our fingers go wrinkly in the bath?

Which Neuron will be most useful to help find the answer?

-ALL:

-Me! Me! Me! Oh, me!

Will it be fabulous Felix?

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

Will it be beautiful Belle?

I send messages to brain from ear. If there's a sound, I'll 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'm your taste buddy whenever you eat!

It's Felix!

CHEERING

-ALL:

-Go, Felix! Go, Felix! Go, Felix! Go, Felix!

Go, Felix! Go, Felix!

Go, Felix!

Marvellous. A little touch can mean so much, Nina.

Today's question is, why do our fingers go wrinkly in the bath?

We use our fingers to touch and feel,

so I'll be relying on Felix the touch Neuron to help.

But stand by, Neurons, I may need help from all of you.

I need to get organised, the experimenters will be here soon!

Florence loves writing stories, her friend Levi loves pasta,

but both want to find out about wrinkly fingers.

So today, for one day only, Florence and Levi become...

the experimenters!

-Hi, guys!

-TOGETHER: Hi, Nina!

Welcome to my science lab, come in, come in!

Now, your question is, why do our fingers go wrinkly in the bath?

So, why do you want to know that?

Because whenever I have a bath, my fingers go all wrinkly

and I want to know why.

Huh! Well, my fingers and toes go wrinkly in the bath too,

so this is a great question. On our first experiment

we're going to be using our senses!

-ALL:

-Woo-hoo! A senses experiment! We're ready, Nina!

The first thing we should do is have a look at our fingertips,

so let's see your fingers.

OK, how do they look?

Not wrinkly.

They don't look wrinkly. What do they look like, Levi?

Normal fingers.

Just normal fingers, yeah.

-Let's rub our fingers together, how do they feel?

-Warm.

-Warm and sweaty.

-Are they a bit sweaty?

Yeah, they feel warm. Mine feel a bit dry, actually.

Great! So, do any of your fingers feel or look wrinkly at the moment?

CHILDREN: No.

OK, so you want to know why your fingers go wrinkly in the bath.

Now, your bath is full of warm water, and so is my sink!

Let's soak our hands in the water and see what happens.

We can play with these toys too!

Let's put all of them in.

# Boop-boop! #

-SQUIRT!

-Oh! Hello!

Nina, looks like you're having a great time,

but how are the fingers looking?

Oh! Thanks for reminding me, Luke!

I'm having so much fun, I almost forgot it was an experiment!

OK, so hands up, guys!

Oh, mine are definitely wrinkly, look at that!

-What about yours, Florence?

-They're really bumpy.

-Really wrinkly.

So our fingers were soft and smooth,

and after we've taken them out the water, they've gone wrinkly!

We know the water must have made our fingers go wrinkly!

But we don't know why. Time for another experiment!

OK, guys.

Now, in this experiment, we're also using water,

but our hands will stay nice and dry.

These are soil pellets.

-What's that Nina's using?

-They're soil pellets, Bud.

They're a bit like the mud you get in plant pots.

Watch carefully to see what happens when I add some water.

Ew!

That's amazing! It looks like the pellet is growing.

-What can you see?

-TOGETHER: They've grown!

Yeah! The soil pellet is a bit like a bath sponge,

it's soaked up the water.

In science, when materials do that, we say they absorb water.

And when things absorb water, they get bigger.

Some animals, like frogs, they absorb water all over their bodies!

That's how they drink!

Did Nina say frogs? I LOVE frogs!

Boing! Boing! Boing! Boing! Boing!

Hmm, as I was saying, when our fingertips and toes get wet,

they absorb water, just like a frog, and get a tiny bit bigger!

But what does this have to do with wrinkles?

We need to find out more and I know just the place to go!

Let's go, experimenters! This way!

Off we go for another adventure.

Nina said it's somewhere we can find out more about wrinkles.

Maybe it's the zoo!

Elephants have got lots of wrinkles!

Looks like we're here!

This is a school for people who want to perform in a circus,

like jugglers, acrobats and clowns.

-Can you guess why we're here?

-TOGETHER: No, Nina!

This place is perfect to find clown outfits

and that's what we need for this experiment!

Oh! Circus? Clowns? Dressing up? Yippee!

OK! I think that's enough clowning around.

Ha-ha! How do the costumes make you feel?

I like all the colours, but the costume's far too big!

And the clothes are very baggy.

-The trousers are bunched up around my ankles.

-Yes, you're right.

Because the costumes are too big, the material's gone all wrinkly.

How do your normal clothes feel now?

They fit properly.

Yes, our own clothes are a perfect fit, look...

no wrinkles.

So far we've found out

that when some things get wet they absorb water,

and when they absorb water they get bigger.

And we've found that when we wear clothes that are too big for us,

they go wrinkly.

So...could it be that our fingers go wrinkly in the bath

because they've got bigger?

I know an experiment that should help us find out.

Let's go back to the lab!

OK, first, we're going to cut out the oval shape

on these pieces of paper. OK?

Off you go!

Now, do be careful and watch those fingers!

Scissors can be very sharp.

Thanks, Felix.

Ooh, I love the sound of scissors. Snip, snip, snip!

Brilliant! We're going to place our oval pieces of paper

on top of our fingertips. So, Florence, you come round.

Pick your best oval. Put yours there.

Levi, you can put yours there.

And give it a little push in,

so it sits nice and flat.

Brilliant. I'm giving you a beaker with a little bit of water each.

Levi, that's for you. Florence, one for you.

Carefully, guys, we're going to pour a little water

onto your fingertip. Now, watch closely for any changes, OK?

That's good...

Something's happening! The paper's changing shape!

What's happened to the paper?

It's gone a little bit bumpy and soggy as well.

-Would you say they've gone a bit wrinkly?

-Mm-hm.

The paper has soaked up some water and turned wrinkly,

because absorbing the water has made the paper get bigger.

So this bit of paper is now too big to fit in the hollow,

so it's had to wrinkle up, like the skin on our fingertips does!

So your question was, why do our fingers go wrinkly in the bath?

And we've answered it!

We discovered some things absorb water

and that makes them get bigger.

When things are too big, like clown costumes, they go all wrinkly.

And in the bath, the skin on the tips of our fingers absorbs water

and gets bigger.

Because our fingers stay the same size,

when the skin gets too big,

it goes all wrinkly.

But not to worry, because when it dries out,

the wrinkles all disappear.

I hope that answers your question.

-CHILDREN: Thanks, Nina! Bye!

-Bye!

Lab coat on, Nina?

Lab coat on, Ollie.

Safety gloves on, Nina?

Safety gloves on, Felix.

Don't forget your goggles, Nina.

Goggles are on, Luke. I think we're ready!

# Go, Nina! #

It's been a marvellous day -

all that touching and feeling to explore our fingertips.

Oh, I've had a brilliant day - hearing all those great water noises!

Splish-splash!

I really enjoyed myself today -

those soil pellets had a great earthy smell.

I've had a fabby day!

Especially the dressing up! Oh, that was so funny! Ha-ha-ha!

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

Seeing the paper wrinkle up, just like Nina's fingertips.

Amazing!

Our day's been bursting with experiments.

I hope you've enjoyed it. See you soon, bye!

ALL: Bye!
