Hello there! Oh, silly me!

I just dropped my bottle of fizzy water.

I'm feeling very thirsty today. This will be lovely.

-FIZZING

-Oh! Ho-ho!

Oh, no! Oh, fizzy fountain!

BEEPING

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

ALL: Hi, Nina!

-Hi, guys.

-We've got a question for you.

Why do fizzy drinks make us burp?

That's a great question. Why do fizzy drinks make us burp?

I love fizzy water, but you're right,

it makes me burp sometimes.

Why don't you come down to my lab

and we'll do some experiments to investigate.

-ALL: See you soon, Nina. Bye.

-Bye!

I'm going to need some help to answer this one

and I know who to ask.

OK, Neurons. Time to get to work.

ALL: Neurons at the ready, Nina.

OK, today's question is why do fizzy drinks make us burp?

Which neuron do you think would be useful

in helping find the answer?

ALL: Me! Me! 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 to brain from ear. If there's a sound, I help you hear.

Will it be lovely Luke?

For looking and seeing, day or night,

I 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.

BEEPING

Yippee!

CHEERING

ALL: Go, Bud! 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 why do fizzy drinks make us burp?

Because we use taste when we drink things,

Bud will help me today.

I'd better get the lab ready before the experimenters arrive.

Michael likes skateboarding, Brody likes dinosaurs

and Callum loves rugby.

They all want to know why fizzy drinks make us burp.

Today, for one day only, Michael, Brody and Callum become...

the experimenters!

-Hi, guys.

-ALL: Hi, Nina!

Welcome to my science lab.

You asked, "Why do fizzy drinks make us burp?" Great question.

Why do you want to know?

Because my mummy says burping is rude.

Burping can be rude and embarrassing sometimes.

We should experiment to find out more.

Let's start by using our senses.

ALL: Whoop-whoo! A senses experiment! We're ready, Nina.

To find out why fizzy drinks make us burp,

it's important to know what makes a fizzy drink fizzy.

For our first experiment, I'm going to try

and make this plain water fizz.

Let's check that it's not fizzy at the moment.

Listen carefully as I unscrew the lid.

-Did you hear fizzy sounds?

-No.

No, so we know it's not fizzy.

Now I'm going to add something called frozen carbon dioxide,

which is often called dry ice.

Watch and listen carefully.

BUBBLING

FIZZING

Look at all those fizzy bubbles! Amazing!

What can you see happening in the water?

Fizzy!

Yes, the frozen carbon dioxide, or dry ice,

has turned into gas that we can see in the water.

Most gasses are invisible

and carbon dioxide is an invisible gas too.

When we add it to water,

we can see it there because it makes gassy bubbles.

Now open your ears and listen carefully.

FIZZ AND POP

-Oh!

-So what did you hear?

A fizzing noise.

-What made the fizzing noise?

-Invisible gas.

The fizzing we hear is the carbon dioxide

escaping from the top of the water.

All fizzy drinks are fizzy because of gas.

When gas is released, it makes a sound.

What does this sound have to do with fizzy drinks making us burp?

We need to do another experiment and we're going to go somewhere

that has some very interesting sounds.

ALL: Yey!

Here we go! I can't wait to see where we'll end up today!

Nina said it's somewhere with interesting sounds.

Maybe it's a noisy factory.

Or a farm with lots of animal noises.

BUD MAKES OINKING NOISES

Moo! Ha-ha-ha-ha-ha!

I don't smell any farm animals, Bud.

This lighthouse shines a bright light when it's dark

to warn ships not to come too close to the rocky shore.

We'll find out why we've come here to talk about burping in a minute.

First, have you ever burped when you haven't had a fizzy drink?

-Sometimes when I'm eating I burp.

-Just after dinner.

You sometimes burp too, don't you, Nina?

Yes, actually, Bud.

That's because if we eat too quickly,

we can swallow air with our food.

Air is a type of gas and when we swallow it,

it goes down our food tube and into our tummy.

What happens if we get too much gas in our tummies?

I've got a noisy experiment that will help us find out.

To start off, we're going to very gently blow into these party horns.

Just use a little bit of breath.

RUSTLING AND QUIET TOOTS

-How do those horns sound?

-Not very loud, Nina. Squeaky.

OK, this time take a big, deep breath and blow as hard as you can.

LOUD TOOTS

-What did you notice there?

-That was louder.

Yes. By using a bigger breath, you made the horn sound much louder.

Now let's try using these hand horns. Pass it along.

HONKING

SHE LAUGHS

Wa-hay! Brilliant honky sounds, Nina. Honk-honk! Honk-honk!

THEY LAUGH

Are these louder or quieter than party horns?

ALL: Louder.

That's because squeezing pushes lots of air through the horn

and the more air there is, the louder the noise.

I've brought you to this lighthouse because it has a loud horn.

-Are you ready?

-ALL: Yeah!

FOGHORN BLARES

FOGHORN BLARES

-That horn was so loud, Nina!

-It was, Belle.

It has to be really loud because it's a foghorn.

When it's foggy, ships can't see light from the lighthouse

so the lighthouse keeper sounds the really loud foghorn.

Why was the foghorn louder than the other horns?

More air?

Exactly. There was more air pumped through the horn

and this made a much louder sound.

This is a bit like our tummies.

When gas builds up in our tummies

from drinking fizzy drinks or swallowing too much air as we eat,

our clever body gets rid of it by making us burp.

The more air involved in the burp, the longer and louder it will be.

How is this burpy sound made by our body?

Let's go back to the lab to experiment.

THEY ALL CHEER

In front of you, you have a bottle lid with a balloon attached.

The lids have a hole in them.

I'm going to pour some salt through the hole and into the balloon.

Whoop! I poured salt into your balloons earlier.

Next we're going to take the lid off the fizzy water bottle

and replace it quickly with our special balloon lids.

Let's take the lid off our fizzy water bottle.

Then quickly pop the special balloon lid on.

Once you're happy that's on nice and tight,

you can gently take the clip off.

That's good. Pop that down. OK, guys.

When I count to three, lift up the balloon

and let the salt pour into the fizzy water.

OK. One, two, three...

..lift up the balloon!

GASPS

THEY LAUGH

The salt has made all of the gas in the fizzy water escape in one go

into the balloon, and that's why it got bigger or expanded.

But the best part of the experiment is yet to come.

What I need you to do now is remove the balloon from the lid.

Now hold onto the neck of the balloon tightly.

We don't want air to escape, it might spoil the surprise.

Yes! I love surprises!

Now we're going to let the air out of our balloons.

I'll go first.

SQUEAKING

THEY LAUGH

-OK, guys. It's your turn. Go!

-SQUEAKING

What brilliant noises!

The air escaping from the necks of our balloons

is like what happens in our bodies when we burp.

There's a bit of muscle at the top of the food tube

and when a gassy burp escapes from our tummies,

it pushes up past the muscle and makes it wobble back and forth.

It's this wobble that makes the burp sound.

So your question was, "Why do fizzy drinks make us burp?"

I think we have answered it.

Sometimes when we drink a gassy drink or eat too quickly

and swallow lots of air with our food, gas builds up in our tummies.

If there's too much gas, our brilliant bodies

make us burp to get rid of it.

So because fizzy drinks have lots of a special gas inside them,

called carbon dioxide, they can often make us burp.

Remember we should always try to cover our mouths when we burp.

It can be rather rude. I hope that's answered your question.

-ALL: Thanks, Nina. Bye.

-Bye!

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

Seeing all those beautiful bubbles fizzing in the water.

I've had a brilliant day. The foghorn was so loud!

Wah-wah!

It's been a marvellous day.

Feeling the balloon fill up with gas was exciting.

I've had a fabby day! The burpy balloon experiment was so funny!

Ha-ha-haa ha-ha!

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

-See you again soon. Bye!

-ALL: Bye!
