'Animals are amazing.' | 0:00:02 | 0:00:04 | |
That's astonishing. | 0:00:04 | 0:00:05 | |
'And the more we find out about them, the more amazing they seem.' | 0:00:05 | 0:00:10 | |
That feels pretty harsh. | 0:00:10 | 0:00:11 | |
'That's why scientists all over the world | 0:00:11 | 0:00:14 | |
'are trying their best to copy them...' | 0:00:14 | 0:00:17 | |
This is the future. | 0:00:17 | 0:00:18 | |
'..making brand-new inventions...' Tomato juice. | 0:00:18 | 0:00:21 | |
'..based on what animals can do.' | 0:00:21 | 0:00:23 | |
'Some are astounding.' | 0:00:24 | 0:00:26 | |
We've just dived under the sea. | 0:00:26 | 0:00:27 | |
'Some bizarre.' | 0:00:27 | 0:00:29 | |
This is not at all pleasant. | 0:00:29 | 0:00:31 | |
Yes, it's gone! | 0:00:33 | 0:00:34 | |
'But they're all inspired by the miracles of nature.' | 0:00:34 | 0:00:39 | |
Episode One. | 0:00:41 | 0:00:42 | |
How scientists might design the ultimate crash helmet, | 0:00:44 | 0:00:49 | |
by studying one small bird. | 0:00:49 | 0:00:51 | |
All-new crash helmets are subjected to a drop test | 0:00:55 | 0:00:58 | |
to ensure they offer enough protection. | 0:00:58 | 0:01:02 | |
And not just any old drop, | 0:01:02 | 0:01:04 | |
a drop from the top of the highest helmet drop-tower in Britain - | 0:01:04 | 0:01:09 | |
50 feet, straight down onto a solid steel pipe. | 0:01:09 | 0:01:14 | |
It's an impact speed of around 60 miles per hour, | 0:01:18 | 0:01:22 | |
but helmets can only survive an impact like this once. | 0:01:22 | 0:01:26 | |
And that's where the woodpecker comes in. | 0:01:27 | 0:01:31 | |
The great spotted woodpecker, to be precise. | 0:01:31 | 0:01:35 | |
The biggest head-banger on the planet. | 0:01:35 | 0:01:39 | |
It drills a hole up to four inches deep | 0:01:47 | 0:01:50 | |
through solid wood | 0:01:50 | 0:01:51 | |
to get at the larvae of wood-boring beetles. | 0:01:51 | 0:01:55 | |
Which puts its head, and its brain, through an astonishing pounding. | 0:01:56 | 0:02:01 | |
The thing is, and this is an incredible figure, | 0:02:04 | 0:02:08 | |
every time the woodpecker's beak strikes the tree, | 0:02:08 | 0:02:12 | |
its head is subject to 1,200G. | 0:02:12 | 0:02:15 | |
Which is enormous. | 0:02:15 | 0:02:17 | |
In a crash, a human could only survive a fraction of that. | 0:02:17 | 0:02:23 | |
So, can the woodpecker help us build a better helmet? | 0:02:23 | 0:02:27 | |
Engineer John Powell is trying to find out. | 0:02:30 | 0:02:33 | |
John, I'll be honest, it looks nothing like a woodpecker. | 0:02:35 | 0:02:38 | |
It doesn't look like a woodpecker, but we've replicated | 0:02:38 | 0:02:41 | |
the entire woodpecker brain support system. | 0:02:41 | 0:02:43 | |
A woodpecker has a sort of shock absorber | 0:02:44 | 0:02:48 | |
between its beak and its head. | 0:02:48 | 0:02:50 | |
And another between its skull and its brain. | 0:02:52 | 0:02:55 | |
And by using the same four flexible layers, | 0:02:55 | 0:02:59 | |
John reckons his canister can survive massive impact. | 0:02:59 | 0:03:04 | |
But we're not just going to take his word for it. | 0:03:06 | 0:03:09 | |
To find out just how good this container is, | 0:03:12 | 0:03:15 | |
we are going to drop it with something delicate inside it. | 0:03:15 | 0:03:19 | |
Something like this. | 0:03:19 | 0:03:21 | |
Not this. | 0:03:23 | 0:03:25 | |
This. | 0:03:25 | 0:03:26 | |
A bulb. Now that IS delicate. | 0:03:29 | 0:03:33 | |
We've got glass, thin glass, and the filament inside. | 0:03:33 | 0:03:37 | |
I can't get these things home from the store without breaking them, | 0:03:37 | 0:03:40 | |
I wouldn't expect this to survive a fall from a kitchen work surface. | 0:03:40 | 0:03:44 | |
But today we are going to drop it from space. | 0:03:44 | 0:03:48 | |
Here is the precious cargo. | 0:03:54 | 0:03:57 | |
John, I mean, this... It's not a specially prepared bulb or anything. | 0:03:57 | 0:04:01 | |
No, this is a regular light bulb we bought from the hardware store. | 0:04:01 | 0:04:04 | |
-It's just off a shelf? -Yes. | 0:04:04 | 0:04:06 | |
The real trick is to get everything not to move. | 0:04:06 | 0:04:09 | |
Everything takes a lot of shock if it can't move, | 0:04:09 | 0:04:12 | |
then it can't come over towards the light bulb. | 0:04:12 | 0:04:15 | |
Hopeful, that's a good word for this mission. | 0:04:15 | 0:04:17 | |
Ambitious and hopeful. | 0:04:17 | 0:04:19 | |
But John is confident that his canister, | 0:04:19 | 0:04:22 | |
modelled on a woodpecker's skull, | 0:04:22 | 0:04:24 | |
will survive. | 0:04:24 | 0:04:27 | |
OK, so here is how it's going to work. | 0:04:27 | 0:04:28 | |
Still can't quite believe I'm saying this. | 0:04:28 | 0:04:31 | |
Our canister containing the light bulb | 0:04:31 | 0:04:32 | |
will be suspended underneath the module. | 0:04:32 | 0:04:34 | |
That in turn will be suspended underneath that weather balloon, | 0:04:34 | 0:04:37 | |
which is filled with helium, which is lighter than air, | 0:04:37 | 0:04:40 | |
so that will take the whole lot up. | 0:04:40 | 0:04:42 | |
And up. And up. | 0:04:42 | 0:04:44 | |
Right beyond the edge of the Earth's atmosphere and, well, into space. | 0:04:44 | 0:04:48 | |
I know it sounds silly when you say it, but that's where it's going. | 0:04:48 | 0:04:51 | |
When it's there, down here on the ground in mission control, | 0:04:51 | 0:04:54 | |
which is that van over there, | 0:04:54 | 0:04:55 | |
they will press a button that will release our module | 0:04:55 | 0:04:58 | |
and it will fall all the way back down to Earth with our light bulb. | 0:04:58 | 0:05:02 | |
And then, well, we'll just see what happens. | 0:05:02 | 0:05:04 | |
It's equipped with GPS so they can find it. We'll have a look. | 0:05:04 | 0:05:08 | |
-We're going into space. -HE GIGGLES | 0:05:08 | 0:05:11 | |
'Commencing launch procedure.' | 0:05:11 | 0:05:13 | |
'Five... | 0:05:14 | 0:05:15 | |
'four...three... | 0:05:15 | 0:05:18 | |
'two...one.' | 0:05:18 | 0:05:20 | |
It's up. It's going that way. | 0:05:24 | 0:05:27 | |
It's climbing. | 0:05:27 | 0:05:29 | |
Bye-bye, light bulb. | 0:05:36 | 0:05:38 | |
Good luck on the way back down. | 0:05:39 | 0:05:42 | |
The balloon carrying our woodpecker canister | 0:05:44 | 0:05:47 | |
rises astonishingly quickly - | 0:05:47 | 0:05:49 | |
around 1,000 feet a minute - | 0:05:49 | 0:05:52 | |
and it's already out of sight from the ground. | 0:05:52 | 0:05:55 | |
Time to get myself to mission control. | 0:05:55 | 0:05:58 | |
Just 2,000 feet to go till our designated drop point | 0:05:58 | 0:06:02 | |
and then our canister containing our precious light-bulb cargo | 0:06:02 | 0:06:07 | |
begins its Mach 1 journey back towards Earth... | 0:06:07 | 0:06:10 | |
and a substantial crash landing, which, hopefully, it will survive, | 0:06:10 | 0:06:14 | |
thanks to a technology derived from that of a woodpecker's head. | 0:06:14 | 0:06:19 | |
There it is. Go. | 0:06:22 | 0:06:23 | |
-Yes! -Yes! -There it goes! -It's gone! | 0:06:25 | 0:06:28 | |
Within seconds, the canister is going fast enough | 0:06:30 | 0:06:33 | |
to break the sound barrier. | 0:06:33 | 0:06:35 | |
If there WAS any sound in space, that is. | 0:06:35 | 0:06:39 | |
Yet even at 700-odd miles an hour, | 0:06:39 | 0:06:42 | |
the descent is going to take a remarkable 15 minutes - | 0:06:42 | 0:06:46 | |
now THAT is what I call a drop test. | 0:06:46 | 0:06:49 | |
With the canister now out of sight, | 0:06:50 | 0:06:53 | |
the team remotely detonate the weather balloon. | 0:06:53 | 0:06:56 | |
A parachute launches automatically, | 0:06:59 | 0:07:01 | |
floating the transmitters and cameras safely back down to Earth. | 0:07:01 | 0:07:05 | |
The canister isn't so lucky. | 0:07:07 | 0:07:10 | |
No woodpecker has ever travelled at 700 miles per hour. | 0:07:10 | 0:07:14 | |
No woodpecker has ever plummeted 85,000 feet. | 0:07:16 | 0:07:20 | |
But right now, we're relying on the way a woodpecker | 0:07:22 | 0:07:25 | |
protects its brain | 0:07:25 | 0:07:26 | |
to keep that light bulb intact. | 0:07:26 | 0:07:28 | |
CRASH | 0:07:32 | 0:07:34 | |
With the canister down, we head out as quickly as we can to retrieve it. | 0:07:38 | 0:07:43 | |
But we have no luck. | 0:07:45 | 0:07:46 | |
As night falls, we're still no closer to finding our canister. | 0:07:50 | 0:07:55 | |
DOORBELL CHIMES | 0:08:01 | 0:08:04 | |
Until more than a week later | 0:08:04 | 0:08:05 | |
when John finally finds the cylinder and posts it on to me. | 0:08:05 | 0:08:09 | |
Stickers say, "Fragile, handle with care." It's a bit late! | 0:08:12 | 0:08:15 | |
Right, let's get this open. | 0:08:15 | 0:08:17 | |
It's like the weirdest Christmas ever. | 0:08:19 | 0:08:21 | |
I daren't look. | 0:08:30 | 0:08:32 | |
This suddenly is now the most precious artefact | 0:08:32 | 0:08:35 | |
I shall ever handle. | 0:08:35 | 0:08:37 | |
There it is. | 0:08:40 | 0:08:42 | |
Intact. | 0:08:46 | 0:08:48 | |
From space. | 0:08:48 | 0:08:49 | |
No parachute, no magic. | 0:08:49 | 0:08:51 | |
There is one further test I could do, | 0:08:51 | 0:08:55 | |
cos I did spot over here... | 0:08:55 | 0:08:56 | |
And this does work. Yeah, it does work. | 0:08:58 | 0:09:00 | |
Oh! | 0:09:02 | 0:09:03 | |
Do you know, it might just be intact. | 0:09:05 | 0:09:08 | |
That's not the bulb. That's not been to space. | 0:09:08 | 0:09:11 | |
THIS is our space bulb. | 0:09:11 | 0:09:13 | |
If this works, I will be staggered, | 0:09:13 | 0:09:16 | |
because when the director suggested using a light bulb, I said no. | 0:09:16 | 0:09:20 | |
Oh... | 0:09:20 | 0:09:22 | |
HE LAUGHS | 0:09:22 | 0:09:25 | |
That is astonishing! | 0:09:27 | 0:09:29 | |
Over there is a very happy man indeed, | 0:09:29 | 0:09:31 | |
because I said, "That's just a step too far - it can't possibly work." | 0:09:31 | 0:09:34 | |
That light bulb has been flown up to space and dropped - | 0:09:34 | 0:09:38 | |
the only thing protecting it was this whole system, | 0:09:38 | 0:09:41 | |
which was home-made | 0:09:41 | 0:09:44 | |
and modelled on the way a woodpecker's skull | 0:09:44 | 0:09:46 | |
protects its brain, when subjected to G, pecking trees. | 0:09:46 | 0:09:50 | |
This was subjected to G, landing without a parachute, from space. | 0:09:50 | 0:09:55 | |
I'm staggered! | 0:09:55 | 0:09:56 | |
There are already helmet manufacturers looking at this, | 0:09:56 | 0:10:00 | |
which means, one day, woodpeckers could be life-savers. | 0:10:00 | 0:10:05 | |
And that, I think you'll agree, | 0:10:05 | 0:10:07 | |
has got to be one of the miracles of nature. | 0:10:07 | 0:10:11 |
