SHE WHISTLES

0:00:560:01:00

Hello there! I'm cleaning the workshop.

0:01:000:01:03

Keeping things clean is very important.

0:01:030:01:06

SHE WHISTLES, BEEPING

0:01:060:01:08

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

0:01:080:01:12

BEEPING

0:01:120:01:15

-Hi, Nina!

-Hi, guys!

-We've got a question for you.

0:01:170:01:22

Where does poo go?

0:01:220:01:25

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

0:01:250:01:28

And it's such an important question too.

0:01:280:01:31

-Come over and we'll investigate.

-See you soon, Nina, bye!

-Bye!

0:01:310:01:38

I'll need help to answer this and I know just who to ask.

0:01:380:01:42

OK, Neurons, time to get to work.

0:01:420:01:45

ALL: Neurons at the ready, Nina.

0:02:000:02:02

OK. Today's question is, where does poo go?

0:02:020:02:06

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

0:02:060:02:10

ALL: Me! Me! Me! Oh, me!

0:02:100:02:13

Will it be fabulous Felix?

0:02:130:02:16

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

0:02:160:02:19

Will it be beautiful Belle?

0:02:190:02:21

I send messages to brain from ear. If there's a sound, I'll help you hear.

0:02:210:02:26

Will it be lovely Luke?

0:02:260:02:28

For looking and seeing, day or night,

0:02:280:02:30

I'll help you with your sense of sight.

0:02:300:02:33

Will it be awesome Ollie?

0:02:330:02:35

If it's pongy or whiffy but you can't tell,

0:02:350:02:37

-my messages help your sense of smell.

-Or will it be baby Bud?

0:02:370:02:41

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!

0:02:410:02:46

It's Ollie!

0:02:500:02:51

CHEERING

0:02:510:02:53

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

0:02:530:02:58

Standing by to smell and tell, Nina.

0:03:000:03:04

Today's question is, where does poo go?

0:03:040:03:07

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

0:03:070:03:12

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

0:03:120:03:16

I must get the workshop ready before the engineers arrive.

0:03:160:03:19

Felix likes superheroes. Alec loves birthdays.

0:03:210:03:25

-Elia loves bouncy castles.

-Poo disappears from the toilet.

0:03:250:03:29

-It goes away when we flush the toilet.

-We don't see it again.

0:03:290:03:35

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

0:03:350:03:39

-Hi, guys!

-Hi, Nina.

-Welcome and thanks for your great question.

0:03:420:03:49

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

0:03:490:03:54

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

0:03:540:03:58

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

0:03:580:04:01

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

0:04:010:04:05

germs could build up and we might get ill.

0:04:050:04:07

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

0:04:070:04:11

That's right, Ollie.

0:04:110:04:13

-What happens when we flush the toilet?

-Water takes it all away.

0:04:130:04:19

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

0:04:190:04:23

through this pipe at the back of the toilet.

0:04:230:04:27

This leads to another pipe called a sewer.

0:04:270:04:31

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

0:04:310:04:36

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

0:04:360:04:40

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

0:04:400:04:44

-A sewer must be a very big pipe.

-And smelly!

0:04:440:04:50

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

0:04:500:04:54

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

0:04:540:04:59

We're pretending that this blue water

0:05:010:05:03

is the dirty water from our homes.

0:05:030:05:06

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

0:05:060:05:09

Alec, can you pour it for me?

0:05:090:05:12

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

0:05:120:05:15

-It's going down underground.

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

0:05:150:05:20

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

0:05:200:05:25

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

0:05:250:05:28

-Do you know what it is?

-How does the water get up there?

0:05:280:05:33

Yes, the sewers are pipes under the ground,

0:05:330:05:35

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

0:05:350:05:39

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

0:05:390:05:44

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

0:05:440:05:49

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

0:05:490:05:54

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

0:05:540:05:58

That's it! What can you see happening?

0:06:000:06:03

It's all going down there.

0:06:030:06:05

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

0:06:050:06:09

But when someone flushes their toilet,

0:06:090:06:12

more water is going to flow into the sewer.

0:06:120:06:15

Keep pumping! He-he!

0:06:200:06:23

Elia, are you feeling tired?

0:06:280:06:32

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

0:06:320:06:36

to take all the dirty water from our homes away.

0:06:360:06:40

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

0:06:400:06:43

that's a lot of water to pump.

0:06:430:06:45

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

0:06:450:06:48

without having to push the handle?

0:06:480:06:51

I know just the place where we can find out.

0:06:510:06:54

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

0:06:560:07:00

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

0:07:000:07:03

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

0:07:030:07:08

-But that's impossible!

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

0:07:080:07:12

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

0:07:120:07:17

This is a pumping station and it's so big

0:07:170:07:19

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

0:07:190:07:23

Let's take a look around.

0:07:230:07:25

Look at this!

0:07:370:07:39

That's so big!

0:07:460:07:48

Look at everything moving!

0:07:480:07:50

WHISTLE BLOWS

0:07:500:07:52

Moving and cleaning dirty water is very important.

0:07:520:07:56

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

0:07:560:08:01

and then had to empty it into the street!

0:08:010:08:03

-Stinky! Stinky!

-People must've got sick, Nina.

0:08:030:08:08

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

0:08:080:08:12

engineers helped to save lots of lives.

0:08:120:08:15

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

0:08:150:08:20

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

0:08:200:08:24

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

0:08:240:08:29

It moves dirty water up to be cleaned.

0:08:290:08:33

But this pump is really big

0:08:330:08:35

because it can move dirty water from a whole city!

0:08:350:08:39

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

0:08:390:08:44

Is it a giant, Nina?

0:08:440:08:46

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

0:08:460:08:52

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

0:08:520:08:58

We see it coming out of a kettle.

0:08:580:09:00

Let's see where the steam comes from here.

0:09:000:09:02

It's very hot in here, Nina.

0:09:040:09:06

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

0:09:060:09:11

It's heating up the water to make steam.

0:09:110:09:14

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

0:09:140:09:17

Very wise, Nina. Hot water can burn you.

0:09:170:09:20

This is how a giant steam pump works.

0:09:200:09:24

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

0:09:240:09:28

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

0:09:280:09:31

all the time without stopping.

0:09:310:09:35

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

0:09:350:09:39

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

0:09:390:09:43

So, you asked where does poo go?

0:09:440:09:47

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

0:09:470:09:50

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

0:09:500:09:54

Engineers invented pumps to move the water

0:09:540:09:57

and these pumps can be powered by steam.

0:09:570:10:00

But how does steam make the pump handle move?

0:10:000:10:03

Let's get investigating!

0:10:030:10:05

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

0:10:050:10:10

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

0:10:100:10:15

The blue balloons are the water.

0:10:150:10:17

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

0:10:170:10:20

-because we're just pretending.

-Very wise, Nina.

0:10:200:10:23

So, let's turn on our pretend kettle.

0:10:230:10:27

WHIRRING

0:10:270:10:29

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

0:10:290:10:33

-The balloons are moving.

-The balloons are moving!

0:10:330:10:37

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

0:10:370:10:41

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

0:10:410:10:47

-What's happening to the blue balloons?

-They're jumping up.

0:10:470:10:50

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

0:10:500:10:54

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

0:10:540:10:58

This is what happens inside the giant pump.

0:10:580:11:03

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

0:11:030:11:07

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

0:11:070:11:11

I'll just stop that.

0:11:110:11:14

It was a long time ago that engineers worked out

0:11:140:11:17

that we can use steam to keep things working.

0:11:170:11:20

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

0:11:200:11:24

# Nina and the Neurons! #

0:11:240:11:29

So, your question was, where does poo go?

0:11:290:11:32

I think we've answered it.

0:11:320:11:34

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

0:11:340:11:38

When we flush the toilet,

0:11:380:11:40

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

0:11:400:11:44

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

0:11:440:11:48

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

0:11:480:11:52

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

0:11:520:11:57

-I hope that's answered your question.

-Thanks, Nina, bye.

0:11:570:12:02

You're welcome, bye.

It's been a marvellous day,

0:13:170:13:18

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

0:13:180:13:23

I really enjoyed myself today.

0:13:230:13:26

There were lots of different smells.

0:13:260:13:29

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

0:13:290:13:32

seeing the old steam pump move all that water.

0:13:320:13:36

Engineers help to build the world around us.

0:13:360:13:38

They make things work and use science to solve problems.

0:13:380:13:42

-See you soon, bye!

-ALL: Bye!
