0:00:510:00:54

Oh, hello!

0:00:570:00:58

I've filled the watering can because it's time to water the plants.

0:00:580:01:03

It's very important that plants get enough water and sunlight.

0:01:030:01:07

It helps them grow.

0:01:070:01:09

BEEPING

0:01:110:01:12

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

0:01:120:01:17

ALL: Hi, Nina.

0:01:230:01:24

Hi, guys.

0:01:240:01:25

Nina, we've got a question for you. How do taps work?

0:01:250:01:29

That's a great question. How do taps work?

0:01:290:01:32

A tap is a really useful invention.

0:01:320:01:35

You turn it on, you get lovely water, turn it off, the water stops.

0:01:350:01:39

Come to my workshop and check it out.

0:01:390:01:42

-All: See you soon, Nina, bye!

-Bye!

0:01:420:01:46

I'm going to need help to answer this one and I know who to ask.

0:01:460:01:51

OK, neurons, time to get to work!

0:01:510:01:54

ALL: Neurons at the ready, Nina!

0:02:100:02:12

Today's question is how do taps work?

0:02:130:02:16

Which neuron would be most useful in helping us find the answer?

0:02:160:02:20

-Me!

-Me!

-Me!

-Me!

-Me!

-Me!

0:02:200:02:23

Will it be...fabulous Felix?

0:02:230:02:25

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

0:02:250:02:29

Will it be...beautiful Belle?

0:02:290:02:31

I send messages to brain from ear.

0:02:310:02:34

If there's a sound I'll help you hear.

0:02:340:02:36

-Will it be...lovely Luke?

-Looking and seeing, day or night,

0:02:360:02:40

-I'll help you with your sense of sight.

-Will it be...awesome Ollie?

0:02:400:02:45

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

0:02:450:02:48

-my messages help your sense of smell.

-Or will it be Baby Bud?

0:02:480:02:52

Sour, salty, bitter or sweet. I'm your taste buddy when you eat.

0:02:520:02:57

ELECTRONIC BEEPING

0:02:570:03:00

It's all neurons.

0:03:000:03:02

ALL: Go neurons, go neurons, go neurons!

0:03:020:03:05

ALL: Go neurons, go neurons, go neurons, go neurons!

0:03:050:03:09

All: All neurons hip-hop-happy to help, Nina.

0:03:090:03:13

Today's question is how do taps work?

0:03:130:03:15

When we turn a tap on we can see water flowing out of it,

0:03:150:03:19

and also touch, hear and taste it, so all of the neurons will help us.

0:03:190:03:24

Right, I need to get the workshop ready before the inventors arrive.

0:03:240:03:29

Kieran, Liam and Nicole want to find out all about taps -

0:03:310:03:35

cold taps, hot taps, drip-drip-drop taps. So today, for one day only,

0:03:350:03:40

Kieran, Liam and Nicole become the inventors!

0:03:400:03:44

Hi, guys!

0:03:470:03:48

All: Hi, Nina!

0:03:480:03:50

Come in, come in, welcome to my workshop.

0:03:500:03:53

Your question is how do taps work? Why do you want to know that?

0:03:530:03:57

Cos I like the way you can stop and start the water by turning the tap.

0:03:570:04:02

Let's start by turning some taps.

0:04:020:04:05

Kieran, turn one of those taps on, please?

0:04:050:04:08

And turn it off?

0:04:090:04:11

And turn it on?

0:04:110:04:12

And off.

0:04:120:04:14

On, off! On, off! Ho-ho, that's so clever.

0:04:140:04:19

I love the sound of the water splashing about.

0:04:190:04:23

So we know that to start the flow of water you turn the tap one way,

0:04:230:04:27

and to stop the flow we turn it another way. But how does it do it?

0:04:270:04:32

We need to get inside and have a closer look.

0:04:320:04:36

Taking things apart is my job. It can be dangerous,

0:04:360:04:39

-so don't do this yourself.

-Right, Nina's been specially trained.

0:04:390:04:44

You could get hurt if you take things apart,

0:04:440:04:47

so leave it to the experts.

0:04:470:04:49

Here is the inside of a tap. Let's have a look at it with my Nina-cam.

0:04:490:04:54

Water comes in this pipe all the way into the tap,

0:04:540:05:00

along here and out the spout!

0:05:000:05:03

I'm just going to turn the handle...

0:05:030:05:06

Can you see what happens?

0:05:060:05:08

-The pipe's been blocked?

-Like a plug in a sink?

0:05:080:05:12

That's right, Luke.

0:05:120:05:14

This piece of metal

0:05:140:05:16

moves up and down to open and close the hole.

0:05:160:05:19

There's a piece of rubber at the end that's called a washer.

0:05:190:05:25

The piece of metal was turning.

0:05:250:05:27

That's right, it's called the screw.

0:05:270:05:30

It moves the washer up and down.

0:05:300:05:32

There's something to show you here.

0:05:320:05:35

If I turn the tap on and the hole is opened just a little bit then...

0:05:350:05:42

just a little bit of water comes through.

0:05:420:05:45

But if I turn the tap so the hole is wide open...

0:05:450:05:49

then lots of water comes through really quickly.

0:05:490:05:52

Isn't it clever!

0:05:520:05:54

Simple, but clever!

0:05:540:05:56

Exactly, Felix, and if I turn the tap the other way the washer

0:05:560:06:01

moves down and the tap is off, and the water can't get through.

0:06:010:06:05

And this is because the tap has a screw.

0:06:060:06:10

The screw allows the rubber washer

0:06:100:06:12

to be moved in and out of the hole gradually.

0:06:120:06:16

It isn't just taps that use screws.

0:06:160:06:19

I know something much bigger and exciting that uses them.

0:06:190:06:23

-Shall we go and see an invention in action?

-All: Yes!

-Let's go!

0:06:230:06:27

Oh! I wonder where we're going today.

0:06:320:06:35

I love seeing the big inventions!

0:06:350:06:37

Hmm! What's big and exciting and uses screws? Hmm!

0:06:370:06:45

We'll find out soon! We're here now!

0:06:450:06:48

This is called an Archimedes' Screw.

0:06:490:06:52

Wow! Look at that! Isn't it amazing?

0:06:540:06:59

It's big and it's loud!

0:06:590:07:02

What does it do?

0:07:020:07:04

It doesn't open and close a tap as we saw in the workshop,

0:07:040:07:08

but this screw has a special job.

0:07:080:07:10

As the water runs down the slope it turns the screw round and round,

0:07:100:07:14

and as the screw turns, it makes electricity!

0:07:140:07:18

The screw in the tap is much smaller but its job is just as important.

0:07:180:07:23

-Screws have lots of different jobs, don't they?

-You're right.

0:07:230:07:28

It's not just taps that need screws.

0:07:280:07:30

I think we should go back to the workshop and get inventing.

0:07:300:07:34

Let's go!

0:07:340:07:35

Taps really are handy, aren't they? All it takes is a twist of the wrist

0:07:380:07:43

and out flows the water. But who invented the tap?

0:07:430:07:47

Oh, oh! I know that.

0:07:470:07:50

Thousands of years ago in Greece people were building a palace.

0:07:520:07:56

They were so fed up because there was a constant flow of water

0:07:560:08:00

and they were forever getting their feet wet.

0:08:000:08:04

So they created the first tap.

0:08:040:08:07

Your question was how do taps work?

0:08:160:08:18

so far we've found out that a tap is connected to a water pipe

0:08:180:08:23

and has a screw inside it,

0:08:230:08:25

and when you turn the tap, the screw moves a rubber washer

0:08:250:08:29

in and out of a hole which starts and stops the flow of water.

0:08:290:08:33

We found out lots today about taps

0:08:330:08:35

so we should use it to make our very own tap.

0:08:350:08:39

First, take one of your paper cups,

0:08:390:08:41

then we're going to make a hole in the bottom of the cup.

0:08:410:08:45

About the size of a 10-pence piece, something like that.

0:08:450:08:50

Next we're going to cut this out. Take your scissors.

0:08:500:08:54

Be very careful using scissors, they can be very sharp.

0:08:540:08:58

If it's too fiddly for your fingers, you can ask a grown-up to help.

0:09:000:09:06

Now take your other cup and pop it inside.

0:09:060:09:09

Now we're going to draw round the hole we've just cut out.

0:09:090:09:13

Like that, yeah, very good, perfect.

0:09:130:09:18

And cut this hole out.

0:09:180:09:19

We can fit these cups together now. Look what we've made!

0:09:210:09:25

This is like the hole in the tap. The tap hole is open a little bit,

0:09:250:09:30

then it's opened a lot, then a little bit again...

0:09:300:09:33

and the tap's off!

0:09:330:09:35

To make the tap handle take one of the pieces of paper

0:09:350:09:39

and make a really small fold,

0:09:390:09:41

keep folding it, keeping it nice and tight, nice and small,

0:09:410:09:46

and then just pop a piece of tape on there to keep that in place.

0:09:460:09:52

Next, we'll fix the two parts of our tap handles together,

0:09:520:09:55

like that, and put plenty of sticky tape on.

0:09:550:09:59

Now we need to attach the tap handles to the inside of the tap.

0:10:010:10:06

So sit it over the top and put plenty of sticky tape on.

0:10:060:10:10

A great way to make a handle for a tap.

0:10:110:10:13

Yes, it looks good. The next thing to do

0:10:130:10:16

is make the nozzle for our tap.

0:10:160:10:18

I like the word nozzle, it's very funny.

0:10:180:10:22

I'm glad you approve, Felix.

0:10:220:10:25

Gently roll it, not as tight as for the handles,

0:10:250:10:28

make a much wider hole, let's pop some tape on.

0:10:280:10:32

And now we're to make quite a few snips round here so we can attach it

0:10:340:10:39

far easier to our tap.

0:10:390:10:41

Open the tabs right up

0:10:410:10:42

so it's easier to stick on then you can start taping.

0:10:420:10:46

Next we're ready to fit the two pieces together.

0:10:500:10:53

This is the outside, handle goes inside.

0:10:530:10:56

Let's fill our cups with some lentils. You first, Kieran.

0:10:560:11:02

I like the pattering sound of the lentils going into the cup.

0:11:040:11:09

OK, guys, let's turn our taps on and off!

0:11:100:11:15

Would you look at that! They've made their very own tap.

0:11:190:11:24

Amazing!

0:11:240:11:25

When you turn the handle the hole is opening,

0:11:250:11:28

letting all the lentils flow out.

0:11:280:11:31

If you close the hole a little bit only a few lentils come out,

0:11:310:11:35

then completely turn it off as you close the hole. None comes out!

0:11:350:11:40

Just like a real tap controls the flow of water,

0:11:400:11:44

our tap controls the flow of lentils.

0:11:440:11:47

Your question was how do taps work? I think we've answered it!

0:11:520:11:56

We found when you turn the top of the tap it turns a screw inside.

0:11:560:12:01

When you turn it, the rubber washer moves in and out of the hole,

0:12:010:12:05

stopping and starting the water.

0:12:050:12:07

The screw helps us control how much comes out of the tap

0:12:070:12:11

from a huge gush to tiny trickle.

0:12:110:12:15

So next time you wash your hands you'll know all about top taps!

0:12:150:12:19

-Thank you for coming to see me.

-ALL: Thanks, Nina, bye.

-Bye.

Ah, it's been such a great day, man. The tap is such a great invention.

0:13:220:13:28

Turn it on, the water comes out. Turn it off, the water stops.

0:13:280:13:33

It's been a marvellous day.

0:13:330:13:35

Seeing the inside of the tap was very interesting.

0:13:350:13:39

I've had a fabby day! Especially when they all went out and had fun.

0:13:390:13:45

I've had a brilliant day.

0:13:450:13:47

I liked it when Nina and the inventors made their very own tap,

0:13:470:13:52

the lentils made such a great sound.

0:13:520:13:54

Our day's been bursting with inventions.

0:13:540:13:58

I hope you've enjoyed it and see you soon. Bye!

0:13:580:14:01

ALL: Bye!

0:14:010:14:03

Nina looks at different household inventions and finds out how they work. With the help of her trusty neurons, she examines the items to answer children's questions.

Every time you wash your hands, you're using an amazing invention: the tap! That's why three budding scientists want to know: How do taps work? In this episode, Nicole, Kieran and Liam visit Nina in her workshop and see inside a tap.

Afterwards, they head off to a river to visit something big and twirly that uses the same science. With help from her neurons, Nina tells us about screws and shows us how to make our very own tap using some paper cups and lentils.
