Oh! Hello!

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

ready for my experiment.

BEEPING

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

-ALL:

-Hi, Nina.

-Hi, guys!

We've got a question for you.

How do handles open doors?

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

Door handles are brilliant.

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

-ALL:

-Bye!

Bye.

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

OK, Neurons, time to get to work.

-ALL:

-Neurons at the ready, Nina.

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

Which Neuron do you think'll be most useful?

-ALL:

-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 sight.

Will it be...awesome Ollie?

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

Will it be...baby Bud?

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

BEEPING

-Oh!

-It's Felix.

-CHEERING

-ALL:

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

Go, Felix. Go, Felix.

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

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

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

Felix will be helping us,

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

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

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

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

new handles, old, bright and shiny gold handles.

So today, for one day only,

Joe, Callum and Harris become the inventors!

Hi, guys!

-ALL:

-Hi, Nina.

-Come on in.

Your question was, how do handles open doors?

Why do you want to know that?

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

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

Whoo!

Come through my special door.

Let's have a closer look.

When you push the handle down the latch disappears

and it's so we can open the door.

When we let the handle back up -

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

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

We should get inside and have a look.

So this is the inside of a door handle.

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

Do you see that?

There's a square bit of metal

and when you push the handle down, it turns

and the latch comes in,

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

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

-Will we take the handle off?

-Yes.

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

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

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

and they'll be broken.

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

-We could use our fingers.

-Oh, good thinking.

Be careful. On you go.

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

not for - oh - sticking in door handles.

You're right, Felix.

We might as well put the handle back on.

Harris, try now.

It's much easier with the door handle.

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

A lever makes moving things much easier.

I know lots of inventions that use levers.

-Shall we see another invention?

-ALL:

-Yes!

Brilliant. Let's go!

Off they go.

I really enjoy seeing the big inventions.

What big things use levers?

Think, think, think.

Oh, look, this may give us a clue.

No, still can't guess.

Somewhere around here is something very exciting that uses levers.

Can you see it yet?

HORN TOOTS

-ALL:

-Wow!

Ah! Yeah!

It's a really big...thingamajiggy!

That thingamajiggy, Bud, is called a digger.

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

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

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

-Those levers are bigger than the door handle.

-They are.

Look at this tipper truck - it uses levers too.

The lever helps lift the box and empty everything out.

Who fancies driving it then?

-ALL:

-Me! Me!

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

where experts are watching us.

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

So, now we know more about levers,

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

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

But who invented the door handle?

Oh! Oh! I know that.

For a long, long time

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

DOOR CREAKS

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

He drew how a door handle would work.

Then he made it.

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

Well done, Mr Dorsey.

Your question was, how do handles open doors?

We've found out that a handle is a lever

and it moves a latch which opens the door.

Levers are useful for moving heavy things easily.

That's why diggers and tippers use levers.

We should invent our own door handles.

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

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

using your glue.

Watch out for that sticky glue, Nina!

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

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

That's a lot of pieces.

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

Next, we'll take our brown shapes,

take the paper fastener, slip it through.

Keep your fingers well out of the way.

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

Then gently push the paper fastener through.

Once it's through,

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

to keep it in position.

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

with the markings there on your door handle plan.

You can slip it underneath D.

We can do the same

for this strip as we did for D.

Now, guys, we can fix these pieces on.

Push the paper fastener through.

Well done.

Lastly, we can take our door handles

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

Pop it through the hole. There we go.

Guys, look, our door handle is made.

Let me try my door handle with this door.

Let me try and open the door.

Oh, no! The door's not opening.

You need to open the latch first.

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

Turn the handle

and open the door.

Hello, Nina!

-ALL:

-Hi, Nina!

It works. When we turn the handle

it moves the latch in

and we can open the door. Hey!

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

Your question was, how do handles open doors?

I think we've answered it.

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

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

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

This is because a door handle is a lever

and a lever makes moving heavy things really easy.

That's how handles open doors.

-Thanks for your great question today.

-Thanks, Nina. Bye!

Bye, guys.

If you want to make today's invention go to

the Nina section on the CBeebies website

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

-Bikes!

-Planes!

-Binoculars!

-Televisions!

-And cars!

# We all love inventing

# Whoa, love inventing!

# We all love inventing

# Why don't you try it too?

# Inventions make life easier

-# And help us get things done

-Go inventing!

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

# Go inventing!

-# We all love inventing

-Whoa, go inventing!

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

It's been such a great day, man!

I loved seeing those handles opening and closing doors.

Door handles are a really cool invention.

It's been a marvellous day.

Seeing inside the door handle was such a treat.

I've had a fabby day.

Especially when they all went out and had fun.

I really enjoyed myself today.

The cardboard door handle was fun

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

Our day's been bursting with inventions.

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

-Bye!
