SHE WHISTLES

Hello there! I'm cleaning the workshop.

Keeping things clean is very important.

SHE WHISTLES, BEEPING

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

BEEPING

-Hi, Nina!

-Hi, guys!

-We've got a question for you.

Where does poo go?

That's a great question! Where does poo go?

And it's such an important question too.

-Come over and we'll investigate.

-See you soon, Nina, bye!

-Bye!

I'll need help to answer this 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, where does poo go?

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 Ollie!

CHEERING

ALL: Go, Ollie! Go, Ollie! Go, Ollie!

Standing by to smell and tell, Nina.

Today's question is, where does poo go?

Poo can be whiffy, so Ollie, our smell Neuron, will be helping us.

But, Neurons, I have a feeling I may need help from all of you.

I must get the workshop ready before the engineers arrive.

Felix likes superheroes. Alec loves birthdays.

-Elia loves bouncy castles.

-Poo disappears from the toilet.

-It goes away when we flush the toilet.

-We don't see it again.

Today, for one day only, they are the engineers!

-Hi, guys!

-Hi, Nina.

-Welcome and thanks for your great question.

Where does poo go? To find out, let's start by using our senses!

ALL: Whoop! Woo! A senses experiment! We're ready, Nina!

It's important that we all go to the toilet.

We need to flush the poo away, because if we didn't,

germs could build up and we might get ill.

You should always wash your hands after going to the toilet, Nina.

That's right, Ollie.

-What happens when we flush the toilet?

-Water takes it all away.

That's right. The poo and all the dirty water gets washed down

through this pipe at the back of the toilet.

This leads to another pipe called a sewer.

Whenever we flush the toilet or pull the plug out after having a bath,

all the dirty water leaves our homes and goes into one big pipe.

What? All our dirty water goes down the same sewer?

-A sewer must be a very big pipe.

-And smelly!

It is a bit smelly, but don't worry, sewers are underground.

Let's see what happens to the dirty water after it leaves our homes.

We're pretending that this blue water

is the dirty water from our homes.

And I'd like it to be poured into this pretend sewer.

Alec, can you pour it for me?

Good pouring! Oh! Can you see what's happening?

-It's going down underground.

-That's right! It doesn't stay there.

It then goes to this special place where they take the germs away

and make the water clean again. Oh! But I can see a problem.

-Do you know what it is?

-How does the water get up there?

Yes, the sewers are pipes under the ground,

and the place that cleans the dirty water is above the ground.

Engineers had to work out how to get the dirty water uphill.

Elia, step up here. This is called a pump.

It moves water from one place to the other. Let's see if it can help us.

Can I ask you to push the pump down and up and down and up?

That's it! What can you see happening?

It's all going down there.

The water has moved upwards! He-he-he!

But when someone flushes their toilet,

more water is going to flow into the sewer.

Keep pumping! He-he!

Elia, are you feeling tired?

You can stop, but the pump has to work all the time

to take all the dirty water from our homes away.

As it does this for all the houses in our streets and towns,

that's a lot of water to pump.

I wonder if there's a way to keep a pump moving

without having to push the handle?

I know just the place where we can find out.

Hmm, where you do you think we're going today?

Nina says we'll be able to keep the pump moving

without pushing the handle. We can sit back and relax.

-But that's impossible!

-We'll soon find out! We've arrived!

We're here to answer your question, where does poo go?

This is a pumping station and it's so big

that it can move the dirty water for a whole city.

Let's take a look around.

Look at this!

That's so big!

Look at everything moving!

WHISTLE BLOWS

Moving and cleaning dirty water is very important.

Before we had places like this, people went to the toilet in a pot

and then had to empty it into the street!

-Stinky! Stinky!

-People must've got sick, Nina.

Yes, they did. By working out how to move and clean water,

engineers helped to save lots of lives.

Wow, that's amazing. Engineers are so clever.

They are, Luke, and this is how they move all that water.

This is a giant pump, and it works just like the pump we used earlier.

It moves dirty water up to be cleaned.

But this pump is really big

because it can move dirty water from a whole city!

So, how do they keep this pump moving? It's too big for us to push.

Is it a giant, Nina?

No, Bud, it's not a giant. This is the largest steam pump in the world.

Steam comes from hot water. It's the little clouds that rise in the air.

We see it coming out of a kettle.

Let's see where the steam comes from here.

It's very hot in here, Nina.

It is, isn't it? That's because this is like a giant kettle.

It's heating up the water to make steam.

But we must remember not to stand too close to it.

Very wise, Nina. Hot water can burn you.

This is how a giant steam pump works.

This is where the water's heated to make the steam

and then the steam can push the giant pump handle up and down

all the time without stopping.

But how does the steam keep moving the pump, Nina?

Great question! Let's go back to my workshop to find out.

So, you asked where does poo go?

We've found out that when we flush the toilet,

all the dirty water goes down into a big pipe called a sewer.

Engineers invented pumps to move the water

and these pumps can be powered by steam.

But how does steam make the pump handle move?

Let's get investigating!

We're going to pretend this is a giant kettle.

It'll heat the water just like we saw at the giant pump.

The blue balloons are the water.

Don't go near hot water or steam, but this is OK

-because we're just pretending.

-Very wise, Nina.

So, let's turn on our pretend kettle.

WHIRRING

Oh! Ha-ha! What can you see happening?

-The balloons are moving.

-The balloons are moving!

The blue balloons are doing what water does when it's heated.

It moves around more. When it gets really hot, it becomes steam.

-What's happening to the blue balloons?

-They're jumping up.

Yes, the water has become so hot it's turned into steam.

And because steam moves around so much, it's able to push things up.

This is what happens inside the giant pump.

The steam moves around so much that it's able to push the pump handle

up and down, and the steam can keep it moving all day long.

I'll just stop that.

It was a long time ago that engineers worked out

that we can use steam to keep things working.

It was used to power lots of things like trains, boats and factories.

# Nina and the Neurons! #

So, your question was, where does poo go?

I think we've answered it.

We discovered that poo has germs so it's important to flush it away.

When we flush the toilet,

all the dirty water goes down into a big pipe called a sewer.

The dirty water then has to be moved from the underground sewer

up to be cleaned. Engineers did this by inventing really big pumps

and these can be kept moving by steam or by electricity.

-I hope that's answered your question.

-Thanks, Nina, bye.

You're welcome, bye.

It's been a marvellous day,

pushing the handle up and down to make the water move uphill!

I really enjoyed myself today.

There were lots of different smells.

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

seeing the old steam pump move all that water.

Engineers help to build the world around us.

They make things work and use science to solve problems.

-See you soon, bye!

-ALL: Bye!
