0:00:530:00:54

Oh! Hello!

0:00:570:00:58

Mission accomplished. I've opened a tub of baking powder

0:00:580:01:02

ready for my experiment.

0:01:020:01:04

BEEPING

0:01:050:01:08

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

0:01:090:01:13

-ALL:

-Hi, Nina.

-Hi, guys!

0:01:200:01:23

We've got a question for you.

0:01:230:01:25

How do handles open doors?

0:01:250:01:27

That's a great question. How do handles open doors?

0:01:270:01:31

Door handles are brilliant.

0:01:310:01:33

Come down to my workshop and we'll check it out.

0:01:330:01:37

-ALL:

-Bye!

0:01:370:01:38

Bye.

0:01:380:01:40

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

0:01:400:01:44

OK, Neurons, time to get to work.

0:01:440:01:46

-ALL:

-Neurons at the ready, Nina.

0:02:030:02:06

OK, today's question is, how do handles open doors?

0:02:070:02:11

Which Neuron do you think'll be most useful?

0:02:110:02:15

-ALL:

-Me!

0:02:150:02:17

Will it be...fabulous Felix?

0:02:180:02:20

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

0:02:200:02:24

Will it be...beautiful Belle?

0:02:240:02:27

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

0:02:270:02:31

Will it be...lovely Luke?

0:02:310:02:33

For looking and seeing, day or night, I'll help you with your sight.

0:02:330:02:37

Will it be...awesome Ollie?

0:02:370:02:40

If it's pongy or whiffy but you can't tell, my messages help you smell.

0:02:400:02:44

Will it be...baby Bud?

0:02:440:02:46

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

0:02:460:02:51

BEEPING

0:02:510:02:53

-Oh!

-It's Felix.

-CHEERING

0:02:550:02:58

-ALL:

-Go, Felix. Go, Felix. Go, Felix. Go, Felix. Go, Felix.

0:02:580:03:02

Go, Felix. Go, Felix.

0:03:020:03:05

Marvellous. A little touch can mean so much, Nina.

0:03:050:03:09

Today's question is, how do handles open doors?

0:03:090:03:12

As they're something we need to touch to move,

0:03:120:03:16

Felix will be helping us,

0:03:160:03:17

but stand by, Luke, they're could be interesting things to look at too.

0:03:170:03:22

At your service, Nina. Here's looking at you.

0:03:220:03:26

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

0:03:260:03:31

Joe, Callum and Harris want to find out about door handles -

0:03:320:03:36

new handles, old, bright and shiny gold handles.

0:03:360:03:40

So today, for one day only,

0:03:400:03:42

Joe, Callum and Harris become the inventors!

0:03:420:03:46

Hi, guys!

0:03:490:03:50

-ALL:

-Hi, Nina.

-Come on in.

0:03:500:03:52

Your question was, how do handles open doors?

0:03:520:03:55

Why do you want to know that?

0:03:550:03:58

One of our door handles is broken and we can't open it.

0:03:580:04:01

I have a door handle over here and a very special door.

0:04:010:04:06

Whoo!

0:04:070:04:10

Come through my special door.

0:04:100:04:12

Let's have a closer look.

0:04:130:04:15

When you push the handle down the latch disappears

0:04:150:04:19

and it's so we can open the door.

0:04:190:04:23

When we let the handle back up -

0:04:230:04:25

the latch comes out again, which keeps the door shut.

0:04:250:04:29

We know what a door handle does, but how does it do it?

0:04:300:04:33

We should get inside and have a look.

0:04:330:04:36

So this is the inside of a door handle.

0:04:380:04:42

Let's watch what happens when we turn this handle.

0:04:420:04:45

Do you see that?

0:04:470:04:48

There's a square bit of metal

0:04:480:04:51

and when you push the handle down, it turns

0:04:510:04:54

and the latch comes in,

0:04:540:04:56

so we can open the door just like the door over there.

0:04:560:05:00

What would happen if it didn't have a handle?

0:05:000:05:03

-Will we take the handle off?

-Yes.

0:05:030:05:06

Taking things apart is my job - so don't do this yourself.

0:05:060:05:10

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

0:05:100:05:14

If YOU take things apart you may not be able to put them together again

0:05:140:05:19

and they'll be broken.

0:05:190:05:21

Now...how are we going to turn the axle to open the latch?

0:05:220:05:26

-We could use our fingers.

-Oh, good thinking.

0:05:260:05:29

Be careful. On you go.

0:05:290:05:31

Oh, Nina, fingers are for playing the piano or painting pictures

0:05:350:05:40

not for - oh - sticking in door handles.

0:05:400:05:44

You're right, Felix.

0:05:440:05:45

We might as well put the handle back on.

0:05:450:05:49

Harris, try now.

0:05:490:05:50

It's much easier with the door handle.

0:05:520:05:55

That's because a door handle is something called a "lever".

0:05:550:05:59

A lever makes moving things much easier.

0:05:590:06:02

I know lots of inventions that use levers.

0:06:020:06:05

-Shall we see another invention?

-ALL:

-Yes!

0:06:050:06:09

Brilliant. Let's go!

0:06:090:06:11

Off they go.

0:06:160:06:17

I really enjoy seeing the big inventions.

0:06:170:06:20

What big things use levers?

0:06:200:06:24

Think, think, think.

0:06:240:06:26

Oh, look, this may give us a clue.

0:06:260:06:30

No, still can't guess.

0:06:300:06:33

Somewhere around here is something very exciting that uses levers.

0:06:330:06:38

Can you see it yet?

0:06:380:06:39

HORN TOOTS

0:06:390:06:42

-ALL:

-Wow!

0:06:440:06:45

Ah! Yeah!

0:06:490:06:51

It's a really big...thingamajiggy!

0:06:510:06:56

That thingamajiggy, Bud, is called a digger.

0:06:560:06:59

Diggers dig and lift and move things from place to place.

0:06:590:07:04

Do you see the long bits? They work like levers.

0:07:040:07:07

They make it easier for the digger to move heavy things.

0:07:070:07:11

-Those levers are bigger than the door handle.

-They are.

0:07:110:07:15

Look at this tipper truck - it uses levers too.

0:07:150:07:19

The lever helps lift the box and empty everything out.

0:07:190:07:24

Who fancies driving it then?

0:07:240:07:26

-ALL:

-Me! Me!

0:07:260:07:27

We've come to a special place to drive the trucks

0:07:290:07:32

where experts are watching us.

0:07:320:07:35

This isn't something you're normally allowed to do.

0:07:350:07:39

So, now we know more about levers,

0:07:550:07:58

we need to go to the workshop and get inventing. Let's go!

0:07:580:08:02

Well, there's an awful lot of levering going on.

0:08:040:08:07

But who invented the door handle?

0:08:070:08:10

Oh! Oh! I know that.

0:08:100:08:13

For a long, long time

0:08:140:08:16

people had been trying lots of different ways to keep a door shut...

0:08:160:08:19

DOOR CREAKS

0:08:200:08:22

..until a man called Osbourn Dorsey had an idea.

0:08:350:08:39

He drew how a door handle would work.

0:08:390:08:41

Then he made it.

0:08:440:08:46

His invention was easy to use and did the job perfectly.

0:08:460:08:50

Well done, Mr Dorsey.

0:08:500:08:52

Your question was, how do handles open doors?

0:09:000:09:03

We've found out that a handle is a lever

0:09:030:09:06

and it moves a latch which opens the door.

0:09:060:09:09

Levers are useful for moving heavy things easily.

0:09:090:09:13

That's why diggers and tippers use levers.

0:09:130:09:16

We should invent our own door handles.

0:09:160:09:19

The first thing we'll do is pick up your shapes and let's cut them out.

0:09:190:09:25

And next we're going to stick all our shapes down onto the cardboard

0:09:330:09:39

using your glue.

0:09:390:09:41

Watch out for that sticky glue, Nina!

0:09:410:09:43

Don't want to get it all over your fingers. Yuck!

0:09:430:09:46

Next, guys, we're going to cut out these shapes.

0:09:520:09:56

That's a lot of pieces.

0:10:000:10:02

I wonder how they'll make them into a door handle.

0:10:020:10:05

Next, we'll take our brown shapes,

0:10:050:10:08

take the paper fastener, slip it through.

0:10:080:10:11

Keep your fingers well out of the way.

0:10:110:10:14

Next, we're going to line it up once you're happy with the position.

0:10:140:10:19

Then gently push the paper fastener through.

0:10:190:10:23

Once it's through,

0:10:230:10:24

turn it around and open up the arms of the paper fastener

0:10:240:10:29

to keep it in position.

0:10:290:10:32

Next, take your yellow shape and it'll fit perfectly

0:10:320:10:36

with the markings there on your door handle plan.

0:10:360:10:39

You can slip it underneath D.

0:10:390:10:42

We can do the same

0:10:420:10:44

for this strip as we did for D.

0:10:440:10:46

Now, guys, we can fix these pieces on.

0:10:460:10:50

Push the paper fastener through.

0:10:500:10:52

Well done.

0:10:520:10:55

Lastly, we can take our door handles

0:10:550:10:58

and give it a nice push so they're firmly together.

0:10:580:11:02

Pop it through the hole. There we go.

0:11:020:11:05

Guys, look, our door handle is made.

0:11:050:11:08

Let me try my door handle with this door.

0:11:080:11:11

Let me try and open the door.

0:11:110:11:14

Oh, no! The door's not opening.

0:11:140:11:18

You need to open the latch first.

0:11:180:11:20

Oh, of course! Let's see if it works.

0:11:200:11:22

Turn the handle

0:11:220:11:24

and open the door.

0:11:240:11:26

Hello, Nina!

0:11:270:11:29

-ALL:

-Hi, Nina!

0:11:290:11:30

It works. When we turn the handle

0:11:300:11:33

it moves the latch in

0:11:330:11:35

and we can open the door. Hey!

0:11:350:11:37

Well done, inventors, we've made our very own door handle.

0:11:370:11:42

Your question was, how do handles open doors?

0:11:450:11:48

I think we've answered it.

0:11:480:11:50

First, we found that inside a door handle is a latch

0:11:500:11:54

that has to come in and out to allow us to open and close a door.

0:11:540:11:58

Without a handle, it's hard to do, but with one, it's easy.

0:11:580:12:02

This is because a door handle is a lever

0:12:020:12:05

and a lever makes moving heavy things really easy.

0:12:050:12:09

That's how handles open doors.

0:12:090:12:12

-Thanks for your great question today.

-Thanks, Nina. Bye!

0:12:120:12:16

Bye, guys.

0:12:160:12:17

If you want to make today's invention go to

0:12:230:12:26

the Nina section on the CBeebies website

0:12:260:12:29

and you can make your very own or you may have other ideas.

0:12:290:12:34

-Bikes!

-Planes!

-Binoculars!

0:12:350:12:38

-Televisions!

-Speakers!

-And cars!

0:12:380:12:41

# We all love inventing

0:12:410:12:44

# Whoa, love inventing!

0:12:440:12:47

# We all love inventing

0:12:470:12:50

# Why don't you try it too?

0:12:500:12:53

# Inventions make life easier

0:12:530:12:56

-# And help us get things done

-Go inventing!

0:12:560:12:59

# I always like to take a look at how they work and run

0:12:590:13:04

# Go inventing!

0:13:040:13:05

-# We all love inventing

-Whoa, go inventing!

0:13:050:13:11

# We all love inventing Why don't you try it too? #

0:13:110:13:17

It's been such a great day, man!

0:13:170:13:21

I loved seeing those handles opening and closing doors.

0:13:210:13:25

Door handles are a really cool invention.

0:13:250:13:28

It's been a marvellous day.

0:13:280:13:30

Seeing inside the door handle was such a treat.

0:13:300:13:34

I've had a fabby day.

0:13:340:13:36

Especially when they all went out and had fun.

0:13:360:13:41

I really enjoyed myself today.

0:13:410:13:43

The cardboard door handle was fun

0:13:430:13:46

especially when the door popped open and we saw Nina behind it. He-he!

0:13:460:13:51

Our day's been bursting with inventions.

0:13:510:13:55

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

-Bye!
