'Animals are amazing.'

0:00:020:00:04

That's astonishing.

0:00:040:00:05

'And the more we find out about them, the more amazing they seem.'

0:00:050:00:10

That feels pretty harsh.

0:00:100:00:11

'That's why scientists all over the world

0:00:110:00:14

'are trying their best to copy them...'

0:00:140:00:17

This is the future.

0:00:170:00:18

'..making brand-new inventions...' Tomato juice.

0:00:180:00:21

'..based on what animals can do.'

0:00:210:00:23

'Some are astounding.'

0:00:240:00:26

We've just dived under the sea.

0:00:260:00:27

'Some bizarre.'

0:00:270:00:29

This is not at all pleasant.

0:00:290:00:31

Yes, it's gone!

0:00:330:00:34

'But they're all inspired by the miracles of nature.'

0:00:340:00:39

Episode One.

0:00:410:00:42

How scientists might design the ultimate crash helmet,

0:00:440:00:49

by studying one small bird.

0:00:490:00:51

All-new crash helmets are subjected to a drop test

0:00:550:00:58

to ensure they offer enough protection.

0:00:580:01:02

And not just any old drop,

0:01:020:01:04

a drop from the top of the highest helmet drop-tower in Britain -

0:01:040:01:09

50 feet, straight down onto a solid steel pipe.

0:01:090:01:14

It's an impact speed of around 60 miles per hour,

0:01:180:01:22

but helmets can only survive an impact like this once.

0:01:220:01:26

And that's where the woodpecker comes in.

0:01:270:01:31

The great spotted woodpecker, to be precise.

0:01:310:01:35

The biggest head-banger on the planet.

0:01:350:01:39

It drills a hole up to four inches deep

0:01:470:01:50

through solid wood

0:01:500:01:51

to get at the larvae of wood-boring beetles.

0:01:510:01:55

Which puts its head, and its brain, through an astonishing pounding.

0:01:560:02:01

The thing is, and this is an incredible figure,

0:02:040:02:08

every time the woodpecker's beak strikes the tree,

0:02:080:02:12

its head is subject to 1,200G.

0:02:120:02:15

Which is enormous.

0:02:150:02:17

In a crash, a human could only survive a fraction of that.

0:02:170:02:23

So, can the woodpecker help us build a better helmet?

0:02:230:02:27

Engineer John Powell is trying to find out.

0:02:300:02:33

John, I'll be honest, it looks nothing like a woodpecker.

0:02:350:02:38

It doesn't look like a woodpecker, but we've replicated

0:02:380:02:41

the entire woodpecker brain support system.

0:02:410:02:43

A woodpecker has a sort of shock absorber

0:02:440:02:48

between its beak and its head.

0:02:480:02:50

And another between its skull and its brain.

0:02:520:02:55

And by using the same four flexible layers,

0:02:550:02:59

John reckons his canister can survive massive impact.

0:02:590:03:04

But we're not just going to take his word for it.

0:03:060:03:09

To find out just how good this container is,

0:03:120:03:15

we are going to drop it with something delicate inside it.

0:03:150:03:19

Something like this.

0:03:190:03:21

Not this.

0:03:230:03:25

This.

0:03:250:03:26

A bulb. Now that IS delicate.

0:03:290:03:33

We've got glass, thin glass, and the filament inside.

0:03:330:03:37

I can't get these things home from the store without breaking them,

0:03:370:03:40

I wouldn't expect this to survive a fall from a kitchen work surface.

0:03:400:03:44

But today we are going to drop it from space.

0:03:440:03:48

Here is the precious cargo.

0:03:540:03:57

John, I mean, this... It's not a specially prepared bulb or anything.

0:03:570:04:01

No, this is a regular light bulb we bought from the hardware store.

0:04:010:04:04

-It's just off a shelf?

-Yes.

0:04:040:04:06

The real trick is to get everything not to move.

0:04:060:04:09

Everything takes a lot of shock if it can't move,

0:04:090:04:12

then it can't come over towards the light bulb.

0:04:120:04:15

Hopeful, that's a good word for this mission.

0:04:150:04:17

Ambitious and hopeful.

0:04:170:04:19

But John is confident that his canister,

0:04:190:04:22

modelled on a woodpecker's skull,

0:04:220:04:24

will survive.

0:04:240:04:27

OK, so here is how it's going to work.

0:04:270:04:28

Still can't quite believe I'm saying this.

0:04:280:04:31

Our canister containing the light bulb

0:04:310:04:32

will be suspended underneath the module.

0:04:320:04:34

That in turn will be suspended underneath that weather balloon,

0:04:340:04:37

which is filled with helium, which is lighter than air,

0:04:370:04:40

so that will take the whole lot up.

0:04:400:04:42

And up. And up.

0:04:420:04:44

Right beyond the edge of the Earth's atmosphere and, well, into space.

0:04:440:04:48

I know it sounds silly when you say it, but that's where it's going.

0:04:480:04:51

When it's there, down here on the ground in mission control,

0:04:510:04:54

which is that van over there,

0:04:540:04:55

they will press a button that will release our module

0:04:550:04:58

and it will fall all the way back down to Earth with our light bulb.

0:04:580:05:02

And then, well, we'll just see what happens.

0:05:020:05:04

It's equipped with GPS so they can find it. We'll have a look.

0:05:040:05:08

-We're going into space.

-HE GIGGLES

0:05:080:05:11

'Commencing launch procedure.'

0:05:110:05:13

'Five...

0:05:140:05:15

'four...three...

0:05:150:05:18

'two...one.'

0:05:180:05:20

It's up. It's going that way.

0:05:240:05:27

It's climbing.

0:05:270:05:29

Bye-bye, light bulb.

0:05:360:05:38

Good luck on the way back down.

0:05:390:05:42

The balloon carrying our woodpecker canister

0:05:440:05:47

rises astonishingly quickly -

0:05:470:05:49

around 1,000 feet a minute -

0:05:490:05:52

and it's already out of sight from the ground.

0:05:520:05:55

Time to get myself to mission control.

0:05:550:05:58

Just 2,000 feet to go till our designated drop point

0:05:580:06:02

and then our canister containing our precious light-bulb cargo

0:06:020:06:07

begins its Mach 1 journey back towards Earth...

0:06:070:06:10

and a substantial crash landing, which, hopefully, it will survive,

0:06:100:06:14

thanks to a technology derived from that of a woodpecker's head.

0:06:140:06:19

There it is. Go.

0:06:220:06:23

-Yes!

-Yes!

-There it goes!

-It's gone!

0:06:250:06:28

Within seconds, the canister is going fast enough

0:06:300:06:33

to break the sound barrier.

0:06:330:06:35

If there WAS any sound in space, that is.

0:06:350:06:39

Yet even at 700-odd miles an hour,

0:06:390:06:42

the descent is going to take a remarkable 15 minutes -

0:06:420:06:46

now THAT is what I call a drop test.

0:06:460:06:49

With the canister now out of sight,

0:06:500:06:53

the team remotely detonate the weather balloon.

0:06:530:06:56

A parachute launches automatically,

0:06:590:07:01

floating the transmitters and cameras safely back down to Earth.

0:07:010:07:05

The canister isn't so lucky.

0:07:070:07:10

No woodpecker has ever travelled at 700 miles per hour.

0:07:100:07:14

No woodpecker has ever plummeted 85,000 feet.

0:07:160:07:20

But right now, we're relying on the way a woodpecker

0:07:220:07:25

protects its brain

0:07:250:07:26

to keep that light bulb intact.

0:07:260:07:28

CRASH

0:07:320:07:34

With the canister down, we head out as quickly as we can to retrieve it.

0:07:380:07:43

But we have no luck.

0:07:450:07:46

As night falls, we're still no closer to finding our canister.

0:07:500:07:55

DOORBELL CHIMES

0:08:010:08:04

Until more than a week later

0:08:040:08:05

when John finally finds the cylinder and posts it on to me.

0:08:050:08:09

Stickers say, "Fragile, handle with care." It's a bit late!

0:08:120:08:15

Right, let's get this open.

0:08:150:08:17

It's like the weirdest Christmas ever.

0:08:190:08:21

I daren't look.

0:08:300:08:32

This suddenly is now the most precious artefact

0:08:320:08:35

I shall ever handle.

0:08:350:08:37

There it is.

0:08:400:08:42

Intact.

0:08:460:08:48

From space.

0:08:480:08:49

No parachute, no magic.

0:08:490:08:51

There is one further test I could do,

0:08:510:08:55

cos I did spot over here...

0:08:550:08:56

And this does work. Yeah, it does work.

0:08:580:09:00

Oh!

0:09:020:09:03

Do you know, it might just be intact.

0:09:050:09:08

That's not the bulb. That's not been to space.

0:09:080:09:11

THIS is our space bulb.

0:09:110:09:13

If this works, I will be staggered,

0:09:130:09:16

because when the director suggested using a light bulb, I said no.

0:09:160:09:20

Oh...

0:09:200:09:22

HE LAUGHS

0:09:220:09:25

That is astonishing!

0:09:270:09:29

Over there is a very happy man indeed,

0:09:290:09:31

because I said, "That's just a step too far - it can't possibly work."

0:09:310:09:34

That light bulb has been flown up to space and dropped -

0:09:340:09:38

the only thing protecting it was this whole system,

0:09:380:09:41

which was home-made

0:09:410:09:44

and modelled on the way a woodpecker's skull

0:09:440:09:46

protects its brain, when subjected to G, pecking trees.

0:09:460:09:50

This was subjected to G, landing without a parachute, from space.

0:09:500:09:55

I'm staggered!

0:09:550:09:56

There are already helmet manufacturers looking at this,

0:09:560:10:00

which means, one day, woodpeckers could be life-savers.

0:10:000:10:05

And that, I think you'll agree,

0:10:050:10:07

has got to be one of the miracles of nature.
