Oh, hello there! I'm just making some paper aeroplanes.

I'm really good at making them, heh-heh, heh!

Let's see how long this one can stay up in the air.

SHE GASPS

Oh, that was a really good one!

It stayed up in the air for ages, ha-ha ha!

BEEPING

Oh! 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 aeroplanes fly?

That's a great question. How do aeroplanes fly?

We're not able to fly, but, luckily for us,

engineers solved the problem by inventing aeroplanes,

so why don't you come down to my workshop and we'll investigate?

-See you soon, Nina. Bye!

-Bye!

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

and I know just who to ask.

OK, Neurons, time to get to work.

-ALL:

-Neurons at the ready, Nina.

OK. Today's question is how do aeroplanes fly?

Which neuron do you think will be most useful

in helping us find the answer?

-ALL:

-Me! Me! 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 sense of sight.

Will it be awesome Ollie?

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

my messages help your sense of smell.

Or will it be Baby Bud?

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

It's Luke!

-ALL:

-Go, Luke! Go, Luke!

Go, Luke! Go, Luke!

Go, Luke! Go, Luke! Go, Luke!

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

Today's question is how do aeroplanes fly?

Because aeroplanes are something we see, Luke, our sight neuron,

will be helping us, but stand by, Neurons -

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

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

Jessica loves dressing up,

Campbell likes reading,

Macy loves drawing and painting.

Aeroplanes are cool!

Aeroplanes go really fast.

How do aeroplanes stay in the sky?

So, today, for one day only,

Macy, Jessica and Campbell become the engineers.

-Hi, guys!

-Hi, Nina.

Welcome to my workshop and thanks for your great question -

how do aeroplanes fly?

To find out the answer, let's start by using our senses.

Woo-woo, a senses experiment! We're ready, Nina.

So have a look over here. I have a toy car and a toy aeroplane.

What's the main difference you can see between them?

The aeroplane has wings, but the car doesn't.

Yes, well done, Bud.

Why do you think aeroplanes have wings and cars don't?

Because aeroplanes need wings to fly.

That's right. So let's do an experiment.

So we know air is all around us, but we can't see it,

so let's try feeling the air.

So let's flap our hands like this.

NINA LAUGHS

Wahey! I can feel the air!

Careful, Bud, you're making it windy over here.

What do you feel?

-Air.

-Yes. Me, too.

And when we can feel air, like the wind blowing,

or when we flap our hands, that's air moving.

OK, stop there!

But do you think that the air around us

could help a big aeroplane fly in the sky?

-No.

-Oh, OK.

Well, let's do another experiment, engineers.

What do you think will happen if I blow across this piece of paper?

Will it go up or down?

It'll go down.

Well, let's see.

LUKE LAUGHS

I thought the paper would drop down.

Now why don't you try and we'll see what happens.

And blow!

When you blow across the paper, it goes up,

but if you stop blowing, it goes down.

The paper is lifted up by the moving air.

So, now we know aeroplanes' wings help them to fly,

air is all around us, even though we can't see it,

and moving air can lift things up.

We're getting closer to finding out how aeroplanes fly,

but to really solve the problem,

we need somewhere with a lot more air.

So, let's go, engineers!

Oh, I wonder where we're going today.

Nina said it's somewhere with a lot of air.

Perhaps it's the seaside, with the wind whistling in off the sea.

IMITATES WIND WHISTLING

Seaside? Oh, I hope so! All those salty, seaweed-y smells!

-FELIX:

-I get the feeling it's not the seaside,

but it does look interesting.

LUKE: Wow!

Aeroplanes look so small in the sky but, close up, they're enormous!

Oh, I'd love to fly like an aeroplane!

Nyoooooooom!

Earlier on, we discovered that moving air could lift things up,

but how does that work for huge, heavy aeroplanes?

Well, this next experiment is great fun.

So, Jessica, if you can take this for me.

Guys, what do you think is holding the balloon in the air right now?

-Jessica's hands.

-That's right.

And what do you think would happen if Jessica let go of the balloon?

It'll fall down, Nina.

Well, let's see, shall we?

FAN WHIRS

BELLE: Wow! That's a great noise! Ha-ha!

Jessica, come forward and hold the balloon nice and still here,

and when I say, I want you to let go of the balloon gently, OK?

OK.

So gently let go of the balloon now!

LAUGHTER

ALL: Hooray!

Ooh-ooh, ooh-ooh, ooh!

And let go.

Yay!

Woo!

Brilliant!

Ah, fantastic, guys!

Now, what do you think will happen if I switch the machine of?

It will fall into the fan.

OK. Well, let's have a try.

Woo-woo, woo-woo!

NINA LAUGHS

It didn't fall in, but it did fall down. Ha-ha!

You're right. When the air stopped blowing, the balloon fell down,

and that's because air needs to be moving to lift things up.

So let's see what happens if we try something heavier. Aha!

I'm going to sit it here and I'm going to turn it on.

Oh! The beach ball's not lifting so high, Nina.

That's right, Luke.

Because the beach ball is heavier than the balloon,

it's more difficult for the air to lift it up.

Let's turn up the speed of the fan.

Wow, it's going higher!

Ha-ha ha, yeah!

This shows us that the heavier the object,

the faster the air needs to move to lift it up.

So, to lift a great big aeroplane,

air has to move incredibly fast across the aeroplane's wings.

But how does this happen?

Come on, engineers, let's investigate further.

We're going to try and fly these lovely kites, and I'll go first.

Ho-ho!

Here we go.

-Oops!

-SHE GIGGLES

Could anyone guess why my kite didn't fly?

Because there's no wind blowing, Nina.

Yes. Kites usually fly in the wind.

The air moves across them and lifts them up.

So how can we get air to move across our kites?

You could try running with the kites, Nina.

Running with the kites?

That's a brilliant idea, Felix! Ha-ha! Let's try it.

Three, two, one, go!

GIGGLING

Ha-ha, that was great fun!

By running with our kites, we're like the engines,

pulling them through the air quickly and making them fly.

But our kites are much lighter than an aeroplane,

so let's see what happens if we make our kites heavier

by adding teddy bear pilot.

Three, two, one, go!

Woo, hoo-hoo, hoo!

LAUGHTER

Faster, faster, faster, faster!

Phew! That was hard work!

What did you notice about our kites,

once the teddy bear pilots had been attached?

We had to run faster to get them to fly.

Yes. When the kites got heavier,

they needed the air to move faster across the wings to lift them up,

and it's the same for aeroplanes.

Aeroplanes have big, powerful engines

that move them forward very, very fast,

and this makes the air move over their wings really quickly

and lifts them up.

So, your question was how do aeroplanes fly

and I think we've answered it.

First, we found out that air is all around us,

even though we can't see it,

and if it's moving, it can lift things up.

We also learned the heavier the object,

the faster the air has to move to lift it.

Because aeroplanes are big and heavy,

they need powerful engines to move them forwards really fast.

This gets the air to move across the wings really quickly

and lifts them up.

So I hope that's answered your question.

Thanks, Nina. Bye!

You're welcome. Bye!

It's been a marvellous day.

I couldn't believe the paper lifted when Nina blew on it.

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

Especially seeing all those amazing aeroplanes up close.

I really enjoyed myself today.

The engineers had such good fun flying their kites.

And, remember - engineers helped to build the world around us,

they make things work and use science to solve problems.

See you again soon. Bye.

ALL: Bye!
