Oh, hi! Today's show is all about mixing things together.

Some things mix easily, like water and paint when you're painting

and some things don't - watch this.

-I'm going to pour some oil into this water. Do you think it'll mix?

-Yeah.

-Let's see.

No, it doesn't.

The oil isn't mixing with the water, it's sitting like a layer on top.

Now I'm going to put some drops of colour into this water here.

Look at that! It's mixing into the water.

The colour is mostly made of water so it mixes easily.

Now, what do you think will happen

if I put drops of colour into the oil?

-Will it mix together like it did with the water, or not?

-No.

Look at that!

It doesn't mix in at all, it just stays together.

That's because the colour is mostly made of water

and we already know oil and water don't mix.

There's one more thing I want to show you.

If I use my pencil...

Isn't that brilliant! Fantastic.

I'm poking through the colour there, pushing through the oil into the water,

the colour doesn't mix with the oil, but it does with the water,

so as soon as it touches, it bursts into loads of colour.

Oh, thank you, thank you very much.

-Thank you for coming and I shall see you all again soon. Bye!

-Bye!

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

Hi, Nina, I've got a question for you.

Why is your tongue wet?

Great question!

Why IS your tongue wet?

Hmm, mine's definitely wet, but I wonder why?

Fantastic! I'd love to help you find out.

-Thanks, Nina.

-See you soon.

I think we'll need help to answer this one

and I know just who to ask.

OK, Neurons, time to get to work.

Neurons at the ready, Nina.

OK, today's question is why is your tongue wet?

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

-Me!

-Me!

-Oh, me!

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, brain to ear If there's a sound, I'll help you hear

Will it be lovely Luke?

For lookin' and seein', day or night I'll help you with your sense of sight

Will it be awesome Ollie?

If it's pongy or wiffy, 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 Bud.

-Yippee!

Go, Bud! Go, Bud! Go, Bud!

Go, Bud! Go, Bud! Go, Bud!

Go, Bud.

Give me a taste of the action, Nina.

Today's question is about your tongue so Bud will be helping us out.

OK then, let's go.

'In the town of Aviemore lives Corinne and her mum and dad.'

'They're a regular family, but today, for one day only,

'they are...

'the Experimenters!'

-Hi, everyone.

-Hi, Nina.

-Hi, Corrine, how are you?

-Fine.

Good. Now you want to know why you've got a wet tongue.

So, let me see the tongue, please.

Are you sticking your tongue out at me?! I'm only joking.

I think we'll have to do some experiments to answer your question

but let's start with having a good think about all the things we do with our wet tongues.

Hmm...

'Corinne is thinking about how she uses her wet tongue to stick her stickers in her sticker book.

'Oh, I love stickers!'

'Corinne's dad uses his wet tongue to lick his lips

'ready for eating his yummy sandwich.'

'Mmm.'

'Corinne's mum uses her wet tongue to stick stamps on envelopes.'

We've managed to think of loads of things we do with our tongues. That's fantastic.

Can you think of any more?

But we still haven't answered your question, Corinne, as to WHY our tongues are wet.

I think it's time for an experiment.

Ready, Bud?

It's my big moment! Standing by, ready to send lots of messages!

So, we know we use our wet tongues for lots of things,

but do you know what happens when you don't have a wet tongue?

Have you ever had a dry tongue before?

No? Well, you're about to. This is what we're going to do,

we're going to dry our tongues with a paper towel,

and then once you've done that...

Ha, ha! Listen to Nina - she can't talk properly!

You see, you need your tongue for more than just tasting,

it also helps you to talk.

It's really hard to talk when your tongue's dry.

What I was trying to tell you is you've got to keep your tongue out so it doesn't get wet again.

So if you all take a paper towel,

here's one for you, take a paper towel,

I'd like you to dry your tongues.

Lovely.

And keep them sticking out.

And I'd like you to take a little piece of cracker each

and pop it on your tongue,

put it in your mouth and tell me, can you taste that?

No?

Hmm, interesting.

OK, chew that up and have a drink of water.

Lovely. Have another piece of cracker, pop it on your tongue,

-close your mouth, don't chew - can you taste anything this time?

-Mmm.

Brilliant, you can chew that up now.

So we know you need a wet tongue so you can taste things better

and what makes your tongue wet is saliva.

Our mouth makes loads of it all the time, in fact it makes about this much every day.

-Er, gross!

-I know - it is a lot, isn't it?

But we need saliva to taste things, because when we chew our food or have a drink,

the saliva mixes with that and that's how we taste things.

So, Corinne, that's why our tongues are wet.

Thanks, Nina.

Another brilliant experiment, Nina.

So your tongue has to be wet otherwise it doesn't work properly -

that's so clever.

Do you want to go for a walk and look for some more wet tongues?

Wey-hey, come on, let's go, let's go, let's go!

Ah! Look at those lovely dogs!

They're called Moss and Molly.

I wonder if they've got wet tongues too.

Look, some Highland cows. And a little baby one.

Just like me!

NINA LAUGHS

Oh, look - we're not the only one with wet tongues!

Look at the cow!

Look! Even the dogs have got wet tongues -

I bet they'll be good at tasting too.

I've had a lovely walk - the fresh air's done me the world of good.

I'd better be going, I'm late to meet my friends.

-Bye, Nina.

-Bye, Nina.

Bye, Nina.

Here we are. My friends, Alice, Ruben and Alicia

have been talking about mouth-watering surprises for ages

and as we've been finding out about wet tongues,

I thought today would be the perfect day to let them show me. I can't wait!

-Hi, you guys.

-Hi, Nina.

I can't wait to see what you've got for me. Where are we going?

There.

I was so busy looking for you guys, I hadn't noticed all the fantastic food.

It's making my mouth water just thinking about it.

-Shall we go and taste it?

-Yeah.

Wow. That food look delicious.

Come on, Nina, let's go!

Be patient, Bud, we're just going.

Come on, let's go.

Gracias.

Gracias.

-We've got loads of mouth-watering treats. Are you three ready?

-Yes!

OK - one, two, three, go!

Mmm. I am so glad we have wet tongues

-because if we didn't, we wouldn't be able to enjoy and taste all this yummy food, would we?

-No.

No. I've eaten so much and it's all been lovely,

but I really better be getting back to the science centre, so bye, everyone. Bye-bye!

# It's been a busy, busy day

# Questions answered, experiments done

# We've all used our senses in so many ways

# Tell me, Neurons, what have you done today? #

Wow-wee, I've been a busy baby Bud.

When those tongues were dry, I had to work super hard

because you can't taste properly with a dry tongue.

It needs to be nice and wet.

I was really busy.

I was trying to help you out, little bro,

especially when the tongues were dry - I was trying really hard to smell the crackers.

There were loads of sounds to keep me busy.

Crackers being crunched and lips being licked.

I was working hard too, you know.

There was such a lot to feel - a dry tongue, a wet tongue,

the hard, rough crackers which felt soft and soggy when they were wet.

Yeah, I was pretty busy.

Looking at all those big, wet tongues on the walk was fun.

# Nina and the Neurons

# Nina and the Neurons... #

That was great fun. I hope you've had a sensational time too. Bye!

Bye!
