Oh, hello! I'm just filling the dishwasher.

0:00:580:01:01

There we go, tablet in.

0:01:010:01:03

Close the door and press the button.

0:01:060:01:08

ALARM BEEPS

0:01:090:01:11

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

0:01:110:01:16

Hi, Nina!

0:01:210:01:23

Hi, guys!

0:01:230:01:24

We've got a question for you. How does a dishwasher work?

0:01:240:01:28

That's a great question. How does a dishwasher work?

0:01:280:01:32

Oh, I've just put my dishwasher on!

0:01:320:01:34

A dishwasher's a really useful invention,

0:01:340:01:37

as it washes all our dirty dishes.

0:01:370:01:39

Come to my workshop and check it out!

0:01:390:01:42

See you soon, Nina! Bye!

0:01:420:01:44

Bye!

0:01:440:01:46

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

0:01:460:01:49

and I know just who to ask. OK, Neurons, time to get to work.

0:01:490:01:54

Neurons at the ready, Nina.

0:02:100:02:12

Today's question is - How Does A Dishwasher Work?

0:02:120:02:15

Which Neuron do you think will be best

0:02:150:02:18

at helping us find the answer?

0:02:180:02:20

-Me!

-Me!

-Me!

0:02:200:02:23

Will it be Fabulous Felix?

0:02:230:02:26

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

0:02:260:02:30

Will it be Beautiful Belle?

0:02:300:02:32

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

0:02:320:02:37

Will it be Lovely Luke?

0:02:370:02:38

For looking and seeing, day or night,

0:02:380:02:41

I'll help you with your sense of sight.

0:02:410:02:43

Will it be Awesome Ollie?

0:02:430:02:45

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

0:02:450:02:48

my messages help your sense of smell.

0:02:480:02:51

Or Baby Bud?

0:02:510:02:52

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

0:02:520:02:57

It's Luke!

0:03:010:03:02

Yes!

0:03:020:03:03

Go Luke! Go Luke! Go Luke! Go Luke!

0:03:030:03:07

Go Luke! Go Luke! Go Luke!

0:03:070:03:11

Cool, Nina. I'll be lookin' out to help ya!

0:03:110:03:15

Today's question is How Does A Dishwasher Work?

0:03:150:03:18

Because we see clean dishes come out of a dishwasher,

0:03:180:03:22

Luke will help today, but stand by, Neurons,

0:03:220:03:25

I may need you all.

0:03:250:03:26

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

0:03:260:03:30

Nicole, Casey and Rea want to find out all about dishwashers.

0:03:310:03:36

A yucky plate, a dirty cup, how does the dishwasher clean them up?

0:03:360:03:40

So today, for one day only, Nicole, Casey and Rea become The Inventors!

0:03:400:03:45

Hi, guys!

0:03:480:03:50

Hi, Nina!

0:03:500:03:51

Welcome to my workshop. Thanks for coming down.

0:03:510:03:54

Your question was How Does A Dishwasher Work? Why?

0:03:540:03:58

Dishes go into a dishwasher very dirty.

0:03:580:04:01

But come out really clean.

0:04:010:04:03

They're clever, aren't they? Can you hear that sound?

0:04:030:04:07

-SLOSHING

-Sounds like a dishwasher.

0:04:070:04:09

Yes! And it's making some really strange noises,

0:04:090:04:13

so let's go and have a listen.

0:04:130:04:15

Oh, that is a funny sound,

0:04:150:04:17

it's like a sloshing, splashing, scooshing noise.

0:04:170:04:21

Ah, can you hear that?

0:04:210:04:23

Something sloshing about, Nina.

0:04:230:04:25

There's a sloshing noise inside.

0:04:250:04:28

We know the dishwasher's doing something but can't see what.

0:04:280:04:32

-BEEP

-Oh, I think that's the dishwasher finished!

0:04:320:04:35

Let's just open it up.

0:04:350:04:37

Oh!

0:04:380:04:39

Hey, my teapot's nice and clean!

0:04:400:04:43

Those beakers are sparkling.

0:04:430:04:45

And they smell really nice, too.

0:04:450:04:49

Mmm, a bit soapy and very fresh.

0:04:490:04:52

So, we know WHAT the dishwasher does, but how does it do it?

0:04:520:04:56

Hmm, I think we need to get inside and have a closer look.

0:04:560:05:00

So follow me!

0:05:000:05:02

Taking things apart is my job.

0:05:030:05:05

It can be dangerous so don't do it yourself.

0:05:050:05:08

That's right. Nina's been specially trained to do this.

0:05:080:05:12

If you open up things that use electricity you could hurt yourself.

0:05:120:05:17

OK, let's have a look.

0:05:170:05:19

There's lots of pipes there.

0:05:190:05:21

Yeah, and this one here goes to the top

0:05:210:05:24

and goes to the bottom.

0:05:240:05:26

I wonder where they lead? Let's have a look round the front.

0:05:260:05:30

If you could just step back for me, I'll spin this round.

0:05:300:05:33

And let me just open it up.

0:05:330:05:36

Where do you think the pipes lead?

0:05:400:05:43

Those arms, Nina.

0:05:430:05:44

You're right. The pipes from the back lead to these arms.

0:05:440:05:48

There's one at the top and one at the bottom,

0:05:480:05:51

they have holes in them and they spin round.

0:05:510:05:54

When you turn a dishwasher on, the tablet drops into this basin,

0:05:540:05:58

the basin fills with water and mixes with the tablet.

0:05:580:06:02

The warm, soapy water comes up through the pipes

0:06:020:06:05

and out the holes in the arms.

0:06:050:06:07

Rather than just fall onto the dishes,

0:06:070:06:09

the water squirts round all over them.

0:06:090:06:12

When the water squirts out, it makes the arms turn and spin round.

0:06:120:06:16

That sloshing about we heard was lots of jets of water

0:06:160:06:20

squirting over the dishes, washing and rinsing them.

0:06:200:06:23

Oh, and I know something else that uses jets of water.

0:06:230:06:27

-Shall we go and see another invention in action?

-Yeah!

0:06:270:06:31

Let's go!

0:06:310:06:32

Off they go. I really enjoy seeing the big inventions.

0:06:380:06:42

Hmm, something very big and exciting that uses jets?

0:06:420:06:47

I wonder what that could be.

0:06:470:06:49

Oh goody! I think we're here now!

0:06:490:06:53

OK, guys. We've come to this harbour to see another invention

0:06:530:06:58

that uses jets of water and I think I can hear it coming.

0:06:580:07:02

It's a jet boat and look how quick it's going.

0:07:040:07:07

One of the reasons it goes so fast is because,

0:07:070:07:10

like the dishwasher, it uses jets of water.

0:07:100:07:13

The jet boat takes water from the sea,

0:07:130:07:16

and squirts it out the back really fast.

0:07:160:07:19

In a dishwasher the jets make the arms spin round,

0:07:190:07:23

but in a jet boat the jets of water push it forward. Wow, look at it go!

0:07:230:07:28

Watch you don't get splashed, Nina!

0:07:280:07:31

That jet boat is spraying water everywhere!

0:07:310:07:34

Yeah! It's brilliant, isn't it?!

0:07:340:07:37

Whoosh, whoosh, whoosh, woohoo!

0:07:370:07:40

We know jets of water can make things move, jet boats go forward

0:07:410:07:45

and the arms in a dishwasher spin round.

0:07:450:07:48

But how do they do that?

0:07:480:07:50

To answer that I think we need to go back to the workshop,

0:07:500:07:54

Come on, inventors, let's get inventing!

0:07:540:07:57

So, dishwashers use lots of spraying water to get dishes clean.

0:07:590:08:03

But who actually invented the dishwasher?

0:08:030:08:06

Well, listen up, I can tell you that.

0:08:060:08:10

Over 100 years ago, a lady called Josephine Cochrane

0:08:110:08:15

loved having all her friends round to dinner.

0:08:150:08:18

But once they had gone,

0:08:180:08:20

there was always such a lot of washing up to do.

0:08:200:08:24

So she measured all her dishes, made drawers to put them in,

0:08:250:08:30

added water jets and put it all inside a big box.

0:08:300:08:34

She had invented the very first dishwasher.

0:08:370:08:41

Hooray!

0:08:410:08:43

So your question was How Does A Dishwasher Work?

0:08:520:08:55

We found out that inside a dishwasher are pipes

0:08:550:08:58

that carry water to arms inside.

0:08:580:09:00

They squirt water out their holes.

0:09:000:09:03

And we also know that when the water squirts

0:09:030:09:06

it makes the arms turn round.

0:09:060:09:08

But how does water make the arms spin?

0:09:080:09:11

I think we should get inventing to find out.

0:09:110:09:14

Today we're going to make our very own water jet.

0:09:140:09:17

The first thing we're going to do is pick two straws.

0:09:170:09:21

Have whatever colour you like.

0:09:210:09:23

Now we're going to cut a bit of the end off the straw,

0:09:230:09:27

about that much should do it.

0:09:270:09:30

Yeah! Straws are cool!

0:09:320:09:36

You put them in the top of a bottle and suck like this.

0:09:360:09:39

Oh, lots of yummy juice!

0:09:400:09:43

We're not sucking through straws today, Bud.

0:09:450:09:48

The next thing to do is pop the straws

0:09:480:09:50

through the holes in our bottle.

0:09:500:09:53

So, let's get to it.

0:09:530:09:55

Might do this in front of my Nina-Cam.

0:09:560:09:59

With the bendy end facing out the way.

0:09:590:10:02

Like that?

0:10:020:10:03

That's right.

0:10:030:10:04

Now we're going to secure them in place using a bit of tape.

0:10:090:10:13

Just around the outside of the straws.

0:10:130:10:16

Good.

0:10:220:10:23

Next we're going to take our piece of thread

0:10:240:10:28

and we're going to tie it around the top of the bottle.

0:10:280:10:32

Yeah, and now tie it in a knot.

0:10:320:10:36

There we go, nearly finished, there's just one more thing

0:10:420:10:46

to put in the bottle. What do you think it is?

0:10:460:10:49

Water.

0:10:490:10:50

That's right. A water jet's no good without water,

0:10:500:10:54

so I'm just going to fill it up at the sink.

0:10:540:10:56

Fill it right up to the top.

0:11:030:11:06

And then...

0:11:070:11:08

..woohoo!

0:11:110:11:13

The bottle is spinning round.

0:11:130:11:16

The water's coming out of the straws

0:11:160:11:18

and that's forcing the bottle to spin round. OK, girls, your turn.

0:11:180:11:23

Well done, Inventors, you've made your very own spinning water jet!

0:11:350:11:40

Your question was How Does A Dishwasher Work?

0:11:440:11:48

I think we've answered it. We found out that inside a dishwasher

0:11:480:11:52

are pipes that carry water to arms with holes in them.

0:11:520:11:56

The force of the water as it comes out of these holes

0:11:560:11:59

makes the arms spin round.

0:11:590:12:01

Which means the water squirts all over the dishes

0:12:010:12:04

rather than just up or down. When the warm, soapy water squirts

0:12:040:12:09

over the dishes it washes the dirt away leaving them clean.

0:12:090:12:13

That's how a dishwasher works.

0:12:130:12:15

Thanks for coming down to my workshop today.

0:12:150:12:18

Thanks, Nina. Bye!

0:12:180:12:20

Bye!

0:12:200:12:22

If you want to make today's invention

0:12:230:12:26

just go to the Nina section on the CBeebies website,

0:12:260:12:29

that'll give you all the instructions you need

0:12:290:12:33

to make your very own.

0:12:330:12:34

Or, you may have other ideas of what you want to invent.

0:12:340:12:39

-Bikes!

-Trains!

-Binoculars!

0:12:390:12:42

-Televisions!

-Speakers!

-And cars!

I've had a brilliant day. Hearing the dishwasher,

0:13:210:13:24

sloshing water here, there and everywhere!

0:13:240:13:28

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

0:13:280:13:31

Seeing inside the dishwasher was a real eye opener.

0:13:310:13:35

All those pipes and arms working together to get the dishes clean.

0:13:350:13:39

I've had a fabby day.

0:13:390:13:42

Especially watching the jet boats on the water, they were soooo fast!

0:13:420:13:48

It's been a marvellous day.

0:13:480:13:50

The plastic bottle water jet was very clever.

0:13:500:13:53

It's amazing how water can make something spin

0:13:530:13:57

round and round and round.

0:13:570:13:59

Our day's been bursting with inventions,

0:13:590:14:02

-I hope you've enjoyed it. See you again soon! Bye!

-Bye!

0:14:020:14:06

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.

In this episode, Nicole, Casey and Riha ask: How does a dishwasher work? With the help of lovely Luke the sight neuron, Nina and the girls look inside a dishwasher and find out all about water jets.

They then head off to the harbour to see another exciting invention that uses the same science. In today's watery episode we make our own spinning water jet using straws and a plastic bottle.
