This is Absolute Genius.

0:00:020:00:03

So sit down, buckle up and get ready for take-off!

0:00:030:00:08

Each show, we'll introduce you to a different genius,

0:00:080:00:12

an amazing person who had a genius idea which shaped the world.

0:00:120:00:16

And they will inspire us

0:00:160:00:18

to come up with our own genius idea at the end of each show.

0:00:180:00:22

-But will it be any good?

-Will it be any good?

0:00:220:00:25

It'll be Absolute Genius!

0:00:250:00:27

'And on today's show...'

0:00:280:00:30

-He's nearly there.

-'You'll be struck by the brilliance of one man.'

0:00:300:00:33

'An absolute genius whose powerful ideas changed the world.'

0:00:330:00:38

Prepare to be shocked!

0:00:380:00:40

Today, we're going to introduce to you a real bright spark.

0:01:130:01:16

Yeah, a genius who helped us understand electricity.

0:01:160:01:19

Without him, this show might have looked like this.

0:01:190:01:22

No, don't do that!

0:01:220:01:24

TUMBLING, SHOUTING

0:01:240:01:26

-Oh!

-Ow!

-Ooh!

-Aah!

0:01:260:01:29

THUDDING, SMASHING

0:01:290:01:31

-Did you enjoy that?

-Yeah. Yeah, I did.

0:01:330:01:36

Our whole world is alive with electricity.

0:01:400:01:44

If it hadn't been for today's genius and other pioneers like him,

0:01:450:01:49

we might never have understood its amazing possibilities.

0:01:490:01:53

Life would have been lit by candles.

0:01:540:01:57

Very dark. And very boring.

0:01:570:02:00

So who is today's genius?

0:02:000:02:02

Ladies and gentlemen, I give you...

0:02:020:02:04

Michael Faraday!

0:02:040:02:06

-You all right?

-All right, duck.

0:02:060:02:08

Later on in the show, we'll be coming up with our own genius idea

0:02:080:02:11

when we put one of Faraday's discoveries to the test

0:02:110:02:14

with three-quarters of a million volts of electricity.

0:02:140:02:17

'Enough to stun Dick into silence.'

0:02:170:02:20

'For a bit!'

0:02:220:02:23

But first, let's find out more about the man himself.

0:02:230:02:26

Faraday was fascinated by electricity,

0:02:290:02:32

but what is it?

0:02:320:02:33

Electricity is a form of energy.

0:02:330:02:35

We depend on it for just about everything

0:02:350:02:38

from lighting up our homes to powering our TVS.

0:02:380:02:41

But more than 200 years ago, when Faraday was young,

0:02:410:02:44

none of these things existed.

0:02:440:02:46

Scientists were only just beginning

0:02:460:02:48

to unlock the incredible potential of electricity.

0:02:480:02:51

Faraday was intrigued.

0:02:520:02:54

But only rich and posh sorts got to be scientists,

0:02:540:02:57

and Faraday was neither.

0:02:570:02:59

But what he did have was access to loads of science books

0:02:590:03:02

because, when he was 14, Faraday was a bookbinder's apprentice.

0:03:020:03:05

He used to read about other people's experiments

0:03:050:03:07

and then decided he wanted to do his own.

0:03:070:03:10

-Come on, then.

-Yeah.

0:03:100:03:13

Oh, dear...

0:03:130:03:14

So he came to the Royal Institution, the home of scientific research...

0:03:140:03:19

Don't touch it!

0:03:190:03:21

'..and persuaded them to give him a job as a lab assistant.

0:03:210:03:24

'Here, he made some of his greatest discoveries.

0:03:260:03:28

'You can almost smell the genius in the air!'

0:03:280:03:31

Can you smell a genius?

0:03:310:03:33

Faraday started experimenting with electricity, magnets and wire.

0:03:370:03:41

He invented the first electric motor,

0:03:430:03:45

a way of turning electricity into movement.

0:03:450:03:48

Modern-day motors are used in everything

0:03:520:03:54

from hairdryers to washing machines.

0:03:540:03:56

Look at that. This is actually Faraday's lab.

0:03:560:03:58

This is where he made all of his discoveries about electricity.

0:03:580:04:02

All the little jars and glass vials,

0:04:020:04:04

they all still have his writing all over them

0:04:040:04:06

and under that table, still got his chewing gum under there.

0:04:060:04:09

Well, I've got to put it somewhere!

0:04:090:04:12

Faraday's genius idea was to work out

0:04:120:04:15

the powerful relationship

0:04:150:04:16

between magnets and electricity.

0:04:160:04:18

Faraday found out you can use magnets to make electricity.

0:04:210:04:25

All you have to do

0:04:250:04:26

is move a magnet near a wire to get the electricity flowing and...

0:04:260:04:31

bingo!

0:04:310:04:33

By now, Faraday was becoming just a little bit famous.

0:04:350:04:38

His lectures at the Royal Institution

0:04:380:04:41

were the hottest ticket in town.

0:04:410:04:42

He loved an audience, and they loved him!

0:04:420:04:46

So this is the room

0:04:460:04:47

where Faraday used to perform all his experiments.

0:04:470:04:50

On this very spot, he used to show all the normos,

0:04:500:04:53

you know, the normal people, his experiments

0:04:530:04:55

and try to get them really enthusiastic and excited about it.

0:04:550:04:58

Seriously, it was like some kind of magic show back in the day.

0:04:580:05:01

Let's try it. Yeah?

0:05:010:05:04

Put it away. There's work to be done.

0:05:060:05:09

'To understand more about electricity,

0:05:130:05:15

'we're going to make our own, just like Faraday,

0:05:150:05:18

'then demonstrate it in front of an audience.'

0:05:180:05:21

We're Faradays in the making

0:05:210:05:23

To show us how, here's genius helper Olympia Brown,

0:05:230:05:27

who's in charge of Science Learning at the Royal Institution.

0:05:270:05:30

What was he like as a person?

0:05:300:05:32

Reports of people who knew him and worked here at the Royal Institution

0:05:320:05:35

say that he was a really nice guy

0:05:350:05:37

but he was absolutely fascinating when you heard him talk.

0:05:370:05:40

He had this amazing force of personality and amazing character

0:05:400:05:44

that just kept people entranced with what he was saying.

0:05:440:05:47

He became a bit of a celebrity in his day.

0:05:470:05:49

So back in those days, it wasn't someone who was on Big Brother,

0:05:490:05:52

it wasn't someone in OK Magazine,

0:05:520:05:54

it was people that had a big brain in their head

0:05:540:05:57

and could relate to people, they were the celebrities.

0:05:570:05:59

Yes, scientists were the celebrities of their day.

0:05:590:06:01

But we want to learn the basics of electricity

0:06:010:06:04

so have you anything we can...?

0:06:040:06:05

Absolutely. We've made a small Faraday generator.

0:06:050:06:07

Here we've got a coil of wire around this tube. Inside the tube,

0:06:070:06:11

we've got some very strong magnets

0:06:110:06:13

and here we've got a light.

0:06:130:06:14

There aren't any batteries in that, as you can see,

0:06:140:06:18

so you'd think that light wouldn't work,

0:06:180:06:20

but if I just do a simple bit of shaking...

0:06:200:06:23

Look at that! So how is that working?

0:06:230:06:25

As the magnets move through the coil of wire, it's causing

0:06:250:06:28

electricity to run through the wire and light up the lights.

0:06:280:06:32

So why was this discovery so important?

0:06:320:06:34

In fact, this exact same thing,

0:06:340:06:36

a magnet moving through a coil of wire,

0:06:360:06:38

is used in gas power stations, coal power stations,

0:06:380:06:41

even wind turbines, to generate the electricity that we all use.

0:06:410:06:44

Quite easy to make?

0:06:440:06:45

Yeah, in fact, you guys are going to do it yourselves.

0:06:450:06:48

I'll give you instructions. The stuff's behind you.

0:06:480:06:50

-I'm going to leave you to it.

-Like being back at school!

0:06:500:06:53

'We've got one hour to prepare

0:06:530:06:55

'before recreating Faraday's experiment in front of an audience.

0:06:550:06:59

-'Olympia - any tips?'

-Ah!

0:06:590:07:01

I think you need a passion for science

0:07:010:07:03

-to be a good science demonstrator.

-Don't snip it.

0:07:030:07:06

Stop.

0:07:060:07:08

HE SNIPS No!

0:07:080:07:09

'Just like Faraday,

0:07:090:07:10

'we intend to pull off a perfectly polished performance.'

0:07:100:07:13

It's about moving a magnet through a coil of wire to create electricity.

0:07:130:07:18

-You're making electricity!

-I am!

0:07:180:07:20

But can we do it again, on our own, in front of an audience?

0:07:210:07:25

They can be quite a challenging audience, actually.

0:07:250:07:28

Oh, Faraday. Wish us luck.

0:07:280:07:29

APPLAUSE

0:07:320:07:34

-All right?

-Hey!

0:07:340:07:37

We're going to make a generator.

0:07:370:07:39

-First, we have some copper wire.

-It is a conductor of electricity,

0:07:390:07:42

which means electricity passes right the way through it.

0:07:420:07:45

We've got to get this copper wire onto this tube.

0:07:450:07:47

We'll make it easier using this electric drill.

0:07:470:07:49

Don't go around grabbing your dad's drill at home.

0:07:490:07:52

Stuff it in.

0:07:520:07:53

-See that?

-Then we can speed it up.

0:07:530:07:56

-So, top speed! Nnnn!

-Stop!

0:07:560:07:58

It's in the middle! Oh, you plank.

0:07:580:08:01

-'We've got them in the palm of our hands.'

-Next!

0:08:010:08:04

-Two seconds. I've just got to, er, sneeze.

-'We've forgotten something.'

0:08:050:08:09

Two seconds.

0:08:090:08:11

'Luckily, no-one's noticed.'

0:08:110:08:13

-He's just going to wipe his nose.

-Go away, go away!

0:08:130:08:17

-You sandpaper the ends.

-Oh, yes, that's right.

0:08:170:08:19

Now what we need are the magnets. These aren't any old magnets.

0:08:190:08:22

These are very strong, look, because they've got hold of the screwdriver

0:08:220:08:26

and the scissors.

0:08:260:08:27

So we're going to put the magnets inside there

0:08:270:08:29

and then secure them with a bung on one end

0:08:290:08:31

and a bung on the other end,

0:08:310:08:33

and then we're going to hook this piece of copper wire

0:08:330:08:36

into the back of the battery unit.

0:08:360:08:39

Right, here we are. This is the moment of truth.

0:08:390:08:41

OK, are we ready? We want a countdown

0:08:410:08:44

and we're going to see what happens.

0:08:440:08:45

-ALL:

-Three, two, one...

0:08:450:08:48

He's going to shake it!

0:08:480:08:50

-Yeah, look at that!

-Impressive.

0:08:500:08:52

That's exactly how Faraday put it

0:08:540:08:56

when he stood here about 200 years ago.

0:08:560:08:58

Thank you.

0:08:580:08:59

So this is the point that you get to ask any questions.

0:09:010:09:04

WIND BLOWS

0:09:040:09:07

Boys, time to go.

0:09:070:09:09

And, while we go in search of more of Faraday's genius,

0:09:110:09:14

here are some facts you might not know about electricity.

0:09:140:09:17

The genius top five.

0:09:190:09:21

At five - electric eels produce strong electric shocks

0:09:210:09:25

of around 500 volts that they use for hunting and self-defence.

0:09:250:09:30

Four - from cloud to Earth,

0:09:300:09:32

a lightning strike can be around six miles long.

0:09:320:09:36

At three - Simon Cowell runs entirely on batteries.

0:09:360:09:39

Only joking, we just made that up!

0:09:390:09:42

Ha ha(!)

0:09:420:09:43

Two - you can get a static shock from just walking on a carpet.

0:09:430:09:47

Charge from the floor goes onto your feet and stores up in your body

0:09:470:09:51

until it can escape - often leaving you with a painful shock! Ouch!

0:09:510:09:55

And one - electricity can travel at around 186,000 miles a second!

0:09:570:10:03

Yep, that's even faster than Usain Bolt!

0:10:030:10:06

'Using electricity,

0:10:090:10:10

'we're going to perform our own shocking experiment later.

0:10:100:10:13

'But first, research.'

0:10:130:10:15

Thanks to Faraday's generator,

0:10:180:10:19

electricity can be made on a massive scale,

0:10:190:10:22

so we can all have it in our homes.

0:10:220:10:24

It's transported by miles of cables

0:10:240:10:27

connected up with pylons and substations.

0:10:270:10:30

The people who look after the network

0:10:300:10:32

often have to work with high voltage electricity,

0:10:320:10:35

high enough to cause a deadly shock.

0:10:350:10:37

That's a lot of volts. We're here at the National Grid.

0:10:390:10:42

-If anyone knows about electricity, these people do.

-We don't.

0:10:420:10:45

It says here, "No entry without authority"

0:10:450:10:48

and you are no authority at all.

0:10:480:10:50

Luckily, we know a man that is -

0:10:500:10:53

genius helper Matt Murphy,

0:10:530:10:55

who's worked for the National Grid for 13 years.

0:10:550:10:58

-All right?

-Yeah.

0:10:580:11:00

Now, people see these kind of get-ups all over the countryside.

0:11:000:11:03

-You always hear a humming noise of the electricity.

-Zzz.

-That's good.

0:11:030:11:06

-But you can't hear one here.

-There's a reason for that.

0:11:060:11:08

This is Eakring, which is National Grid's main training centre.

0:11:080:11:12

This is a substation but it's not actually live,

0:11:120:11:14

-so we can train people safely.

-Oh, right. OK.

0:11:140:11:17

-Can we go in, then?

-Yeah, no problem.

0:11:170:11:21

Remember, if you see one of these near your home, don't go in it.

0:11:210:11:25

-All right?

-Right?

0:11:250:11:27

Faraday's discoveries mean

0:11:300:11:32

it's possible to have a constant supply of electricity.

0:11:320:11:35

And so that we never go without it,

0:11:360:11:38

linemen and women carry out essential repairs at scary heights

0:11:380:11:43

as Dom is about to demonstrate!

0:11:430:11:45

Look at these lads up here. That's what you're going to be doing.

0:11:460:11:50

-What are you talking about? I'm not going up there.

-You are.

0:11:500:11:53

There is no chance... Am I going up there?

0:11:530:11:56

-You are.

-Is this live, that pylon?

0:11:560:11:58

-No, that's not live.

-When you see the people going up,

0:11:580:12:01

-you can start realising how big it is, don't you?

-Yeah, yeah.

0:12:010:12:04

You can see they're tiny.

0:12:040:12:05

My heart's actually going like the clappers,

0:12:050:12:08

just watching those lads up there.

0:12:080:12:10

The pylon Dom's working on is a scary 50 metres high.

0:12:130:12:18

It's that one there.

0:12:180:12:19

This one in front of us?

0:12:210:12:23

Is that how high I'm going - right up to that top?

0:12:270:12:30

But on the upside, at least the power's switched off.

0:12:300:12:33

Electricity is so dangerous,

0:12:330:12:35

linemen and women never work on live lines unless they absolutely have to.

0:12:350:12:40

All right, Dom, what we need you to do today

0:12:400:12:43

is change a step bolt.

0:12:430:12:45

Now, a step bolt

0:12:450:12:46

is how we climb the tower.

0:12:460:12:48

With the assistance of one of our instructors,

0:12:480:12:51

I need you to go up there and change that damaged bolt.

0:12:510:12:54

How do you feel about that?

0:12:540:12:56

-Come on, mate.

-Off we go.

0:12:590:13:01

Come back, Dom!

0:13:060:13:07

And while we drag Dom out of hiding,

0:13:070:13:09

here's a shocking tale about the dangers of electricity.

0:13:090:13:12

It's the Not So Genius Idea.

0:13:130:13:16

American inventor Benjamin Franklin

0:13:160:13:19

famously proved lightning is a form of electricity.

0:13:190:13:23

But not all of his experiments went to plan.

0:13:230:13:26

In 1750, he tried to electrocute a turkey for dinner

0:13:270:13:32

to make the meat more tender

0:13:320:13:34

but ended up running a massive electrical current

0:13:340:13:37

through his own body.

0:13:370:13:40

He was lucky to survive!

0:13:400:13:41

So there you have it.

0:13:410:13:43

A not-so-genius way to make your dinner!

0:13:430:13:46

We're not sure who was more shocked - him or the turkey!

0:13:460:13:49

-Not going to be unsafe at all, is it?

-No, no.

0:13:540:13:57

If you lose your footing, this is holding you.

0:13:570:13:59

-Look at that size of that karabiner.

-Are you being of any help at all?

0:13:590:14:02

You're just hanging around like a bad smell.

0:14:020:14:05

-I'm just giving you confidence.

-You're not giving me anything!

0:14:050:14:08

Come on, then, you big...

0:14:100:14:14

electrical metally freak!

0:14:140:14:17

I'll have you!

0:14:170:14:18

I'll sit on you!

0:14:180:14:19

There he goes. Go on, lad!

0:14:220:14:24

The winds are really picking up the higher I get.

0:14:250:14:28

-How's he doing?

-He's not doing too bad.

-Totally terrified.

0:14:280:14:32

Whatever you do, don't look down.

0:14:330:14:37

-Right.

-How was it?

0:14:370:14:39

I lost my confidence halfway up

0:14:390:14:42

and then I just stopped for a minute, regrouped and back up again.

0:14:420:14:46

Now I'm here, I'm OK.

0:14:460:14:48

'Changing a bolt is a fiddly job

0:14:480:14:50

'especially when you're 15 metres up a windy pylon.'

0:14:500:14:54

So what we're going to do is undo that nut.

0:14:540:14:57

You got it?

0:14:570:14:58

Whatever you do, don't lose that washer!

0:14:580:15:01

Cheers.

0:15:010:15:02

'It is vital to keep the National Grid working

0:15:020:15:04

'because without electricity, the country would grind to a halt.'

0:15:040:15:08

-OK, that's nice and tight.

-Yeah, that will do, superb.

0:15:100:15:13

-Now we're up here...

-Yeah?

0:15:130:15:15

-What do you think about going further up?

-No problem.

0:15:150:15:18

You sure you want to do this?

0:15:180:15:20

'Overhead lineworkers must be prepared to work at all heights

0:15:200:15:24

-'to carry out repairs.'

-Use your legs.

0:15:240:15:26

He's only got little legs, poor lad.

0:15:260:15:28

The wind is something else.

0:15:280:15:31

Don't think about it, think about Faraday.

0:15:310:15:33

-Faraday, Faraday.

-He's nearly there.

0:15:330:15:35

Faraday...

0:15:350:15:37

Oh, yeah, I did it!

0:15:370:15:39

I wouldn't speak too soon, mate. You've still got to come down again.

0:15:410:15:45

Right, then. Now, this is the bit that I'm dreading, actually,

0:15:450:15:48

which I think is going to be the difficult bit,

0:15:480:15:50

because you can see where you're going on the way up.

0:15:500:15:54

On the way down, you can't.

0:15:540:15:55

Oh...

0:15:580:16:00

He's almost there

0:16:020:16:03

when THIS happens.

0:16:030:16:05

And THAT's what the safety harness is for!

0:16:080:16:10

Keep concentrating.

0:16:110:16:13

Dominic Wood, ladies and gentlemen!

0:16:160:16:18

Awooga!

0:16:180:16:20

You wouldn't catch me up there.

0:16:200:16:22

-Put the kettle on. I'm parched.

-Well done, mate. Well done.

0:16:220:16:26

But sometimes repairs have to be carried out on live lines

0:16:290:16:33

carrying dangerous electricity.

0:16:330:16:35

That's where Faraday's genius strikes again!

0:16:350:16:38

He discovered people can be shielded from its harmful effects

0:16:400:16:43

by a metal screen, known as a Faraday cage.

0:16:430:16:46

Live line workers wear a type of Faraday cage

0:16:460:16:49

as their suit contains metal thread.

0:16:490:16:51

CRACKLING

0:16:540:16:56

But how does it work?

0:16:560:16:58

Let's find out from our very own genius scientist, Fran.

0:16:580:17:02

She loves a good experiment to explain how things work.

0:17:020:17:05

Step back a bit lower.

0:17:050:17:07

'And she's guaranteed to pop up round the corner

0:17:070:17:09

'just when you need her most.'

0:17:090:17:11

-Ah!

-Hello!

0:17:110:17:13

Yeah, the linesmen gave us this

0:17:130:17:15

because they said if Dom had gone up the pylon when it was live,

0:17:150:17:18

-he'd have to wear one of these suits.

-It's like a giant babygro, isn't it?

0:17:180:17:21

Also known as a Faraday cage.

0:17:210:17:23

It's nothing like a cage. What are you talking about?

0:17:230:17:26

-It works on the same principles as a Faraday cage.

-Explain.

0:17:260:17:29

To know how a Faraday cage works,

0:17:290:17:31

you guys might need to know a bit more about electricity first.

0:17:310:17:34

We do. We were probably taught it at school but to be honest,

0:17:340:17:37

-totally forgotten.

-It's gone.

0:17:370:17:38

All electricity is, is the movement of things that have got charge

0:17:380:17:43

and these charges come in two different flavours, or types,

0:17:430:17:46

and you can get positive and negative charge.

0:17:460:17:49

These positive and negative charges, they can interact

0:17:490:17:52

and play with each other, and they can make certain things happen.

0:17:520:17:56

-Let me show you.

-Experiment time.

0:17:560:17:58

Over here, I have a machine

0:17:580:18:01

and it's going to make each and every one of these pie dishes

0:18:010:18:04

get a negative charge

0:18:040:18:05

and if things have the same charge as each other,

0:18:050:18:07

than they want to move apart, to move away from each other,

0:18:070:18:10

-they want to repel.

-Like magnets.

-A bit like magnets.

0:18:100:18:13

South and north of a magnet goes together,

0:18:130:18:15

-but when you have ones of the same, they move apart.

-Yep.

0:18:150:18:18

-OK, got it.

-So if you want to turn the machine on, Dom.

0:18:180:18:20

-It's not going to hurt?

-No, well...

0:18:200:18:22

Because I don't like that, so...

0:18:220:18:25

MACHINE HUMS

0:18:250:18:27

Oi, oi! Look at that!

0:18:270:18:30

They've all got the same charge, so they're moving away

0:18:300:18:32

-and repelling each other!

-That's brilliant!

0:18:320:18:34

So, they all had a negative charge and wanted to move apart,

0:18:340:18:38

but when things have a different charge,

0:18:380:18:40

they want to move towards each other.

0:18:400:18:42

So if we put something with a positive charge

0:18:420:18:44

near my negatively charged dome,

0:18:440:18:46

the charge would want to move towards it.

0:18:460:18:48

-So that's negative. You want something that's positive.

-Yes.

0:18:480:18:51

He's positive. A positive guinea pig.

0:18:510:18:53

So I'd like you to put your finger near the dome.

0:18:530:18:55

-Listen, I've just been up a pylon, all right?

-You love it.

0:18:550:19:00

I'm going to switch this on

0:19:000:19:01

and you'll put your finger near the negatively charged dome.

0:19:010:19:04

Don't forget, electricity is just the movement of charge

0:19:040:19:06

so when we see that charge moving towards your finger

0:19:060:19:09

-we might see a little electric spark.

-Good, that's nice.

0:19:090:19:13

-Your hair won't look any different.

-Eh?

-So just...

-He loves it.

0:19:130:19:16

Just pop your finger near it.

0:19:160:19:18

I can't! I can hear it crackling!

0:19:180:19:20

Come on, you do it!

0:19:220:19:24

OK, OK, OK.

0:19:240:19:26

So if I hold my finger near it...

0:19:260:19:28

-It is quite scary, isn't it?

-I can hear it. It's buzzing.

0:19:280:19:31

DOME CRACKLES

0:19:330:19:34

-A bit closer!

-Rubbish!

-Bit closer!

0:19:360:19:39

Oh, baby!

0:19:390:19:40

-DOME CRACKLES

-Ah!

0:19:400:19:41

'So what Fran's saying is that opposites attract.

0:19:410:19:45

'Positive and negative charges are drawn to each other,

0:19:450:19:48

'which creates that spark.'

0:19:480:19:50

Now, in terms of explaining a Faraday suit, what happens is,

0:19:560:19:59

if you apply electricity, which is a charge,

0:19:590:20:02

onto the outside of the suit,

0:20:020:20:04

all the negative and positive charges in the material of the suit

0:20:040:20:07

jiggle around in such a way

0:20:070:20:09

that they end up cancelling themselves out on the inside,

0:20:090:20:12

so inside the suit, you end up with no charge.

0:20:120:20:15

So, the linemen's suit is a Faraday cage

0:20:160:20:19

containing positive and negative charges -

0:20:190:20:21

positives, which are drawn to the electricity from the power lines

0:20:210:20:25

and negatives, which are repelled in the opposite direction.

0:20:250:20:28

In all the kerfuffle, they cancel each other out!

0:20:280:20:31

The inside of the Faraday cage becomes a charge-free zone! Genius!

0:20:310:20:37

So, just to recap,

0:20:370:20:38

when you're inside, cos there's no charge, you're fine, you're safe.

0:20:380:20:41

On the outside, thousands of volts of electricity.

0:20:410:20:45

-Yep, hundreds of thousands of volts.

-Hundreds of thousands, even better!

0:20:450:20:48

That sounds like the ideal place for you.

0:20:480:20:51

'We've learned all about Faraday's amazing discoveries...'

0:20:540:20:57

-You're making electricity!

-I am!

0:20:570:21:00

From generating electricity

0:21:000:21:01

to helping protect people doing one of the scariest jobs in the world.

0:21:010:21:05

And now we've come up with our own genius idea,

0:21:070:21:10

inspired by...

0:21:100:21:12

..the Faraday cage!

0:21:140:21:16

We've tracked one down in the English county of Gloucestershire.

0:21:170:21:21

Gloucestershire? I love Gloucestershire!

0:21:210:21:23

Home of cheese rolling, and the Gloucestershire Old Spot pig!

0:21:230:21:27

And the UK's leading high voltage special effects company!

0:21:280:21:32

So, here's the plan.

0:21:320:21:34

Now, we're going to put Faraday's cage to the test

0:21:340:21:37

using just under one million volts of electricity.

0:21:370:21:40

It's going to be absolutely genius, and I cannot wait.

0:21:400:21:44

Our genius idea -

0:21:490:21:51

to test Faraday's cage to the limit with a human volunteer - Dick.

0:21:510:21:56

Our challenge - to see how well it protects him

0:21:560:21:58

from almost a million volts of electricity

0:21:580:22:03

Our problem - if Faraday is wrong...

0:22:030:22:05

Let's not even go there.

0:22:060:22:08

Here it is. The stage for our very own shocking challenge.

0:22:120:22:17

We've got a Faraday cage and a lightning machine,

0:22:180:22:21

ready to generate some serious high volts of electricity.

0:22:210:22:26

Be warned. What we're about to do could blow your mind!

0:22:260:22:30

Electricity is dangerous stuff,

0:22:330:22:35

so we've brought in a qualified genius helper.

0:22:350:22:38

It's Mark Turner, master of high voltage special effects.

0:22:390:22:43

-It just looks wrong, really, does not?

-It does.

0:22:430:22:45

Now, this is the big genius idea. This is the Faraday cage.

0:22:450:22:50

But I've got to say,

0:22:500:22:52

it looks very different to the lovely, cuddly romper suit

0:22:520:22:55

that Fran showed us earlier. It kind of looks like...

0:22:550:22:58

-An iron maiden?

-An iron maiden.

0:22:580:23:00

Somewhere someone would go to die in the mediaeval ages.

0:23:000:23:02

Its nickname is the Cage of Death.

0:23:020:23:05

-Ha-ha-ha! Cage of Death?

-Yeah.

0:23:050:23:07

-You might laugh.

-Are you all right?

0:23:070:23:08

-No, I'm feeling a bit uncomfortable, to be honest.

-Genuinely?

0:23:080:23:11

This actually looks even more scary. Look at the size of it.

0:23:110:23:14

This is the control panel, so we have a safety key,

0:23:140:23:18

a number of dials, so we can alter the amount of voltage you receive.

0:23:180:23:22

-So what's going to happen?

-I'd like to put your friend in there

0:23:220:23:25

and then we're going to turn up the power very slowly

0:23:250:23:27

to 750,000 volts.

0:23:270:23:29

And the lightning you'll see coming at you,

0:23:290:23:32

and it'll be dancing around your head, around the suit,

0:23:320:23:35

and you'll be able to experience Faraday's principle.

0:23:350:23:37

-Would you like to see it working? Would that help?

-Yeah.

0:23:370:23:40

I wouldn't mind seeing it work before I decide...

0:23:400:23:43

-What do you mean "if you decide"?

-Before I go in!

0:23:430:23:46

'Mark's using a machine called a Tesla Coil

0:23:470:23:50

'to generate the electricity.'

0:23:500:23:52

ELECTRICITY BUZZES

0:23:520:23:55

On the head!

0:24:190:24:20

BOTH LAUGH

0:24:200:24:22

It was so funny. It's just going towards your head and that's it.

0:24:220:24:27

Let me ask some questions.

0:24:300:24:33

What does it feel like in there?

0:24:330:24:35

-You won't feel anything.

-Right.

0:24:350:24:37

Is there any documentation in the history of this experiment

0:24:370:24:40

that has ever gone wrong?

0:24:400:24:41

-One person's died in America two years ago.

-Why? What happened?

0:24:410:24:46

He put something outside of the suit.

0:24:460:24:48

If you're in the suit, you're safe.

0:24:480:24:50

-Would you do it? Hmm?

-No.

0:24:500:24:52

Go on. No, not go on. I didn't mean that. I mean, it's up to you.

0:24:590:25:02

-But what...?

-It's up to you.

0:25:020:25:04

What will I feel like, then, in here?

0:25:060:25:08

-You'll feel nothing.

-At all?

-Nothing at all.

0:25:080:25:11

-You'll possibly smell something.

-Like what?

0:25:110:25:14

Your own trouser juice!

0:25:140:25:16

THEY LAUGH

0:25:160:25:18

All right, ladies and gentlemen, we give you the Faraday cage.

0:25:200:25:26

'I'm putting all my trust in Faraday's genius discovery.

0:25:270:25:31

'Faraday, don't let me down!'

0:25:550:25:57

0:25:570:25:59

-All right?

-Yeah.

0:26:040:26:06

-Can't feel a thing?

-No. It smells really weird.

0:26:060:26:09

Do you want it more?

0:26:090:26:11

-No.

-No?

-No more.

0:26:110:26:13

I'm shaking! I'm shaking!

0:26:150:26:19

I'm not surprised.

0:26:190:26:21

You feeling all right?

0:26:210:26:22

It's the weirdest feeling ever.

0:26:220:26:24

Could you see it out the corner of your eye?

0:26:240:26:26

No, cos when it went to the big one, I closed my eyes.

0:26:260:26:29

I just couldn't look any more. But the noise is so loud in there.

0:26:290:26:31

Could you not feel it hitting the cage?

0:26:310:26:34

Oh, yeah, you can feel it this side, it's just shaking around.

0:26:340:26:37

Wait till you watch it back.

0:26:370:26:39

It was insane, this massive bolt of blue.

0:26:390:26:42

The strangest part is the smell.

0:26:420:26:44

The smell of copper just gets really strong.

0:26:440:26:47

That's not, that's not copper.

0:26:480:26:50

THEY LAUGH

0:26:500:26:51

Whatever you do, don't look down.

0:26:520:26:54

'We've seen Faraday's genius in action -

0:26:540:26:57

'from his early discoveries about how to generate electricity'

0:26:570:27:01

to his genius protective cage that keeps live line workers safe.

0:27:010:27:05

And we've tested Faraday's cage to the limit

0:27:060:27:09

with three quarters of a million volts of electricity!

0:27:090:27:14

Ten minutes and a cup of tea later, how are you feeling?

0:27:140:27:16

Feel OK now. Really pleased I did it, but I can truly say

0:27:160:27:19

that's one of the most bizarre experiences I've ever had in my life

0:27:190:27:22

but it does prove that Faraday's discoveries were genius.

0:27:220:27:25

That's very kind.

0:27:250:27:27

Michael Faraday, you are an absolute genius.

0:27:270:27:30

Come on, it's late. Hey, turn off the lights, will you?

0:27:300:27:33

Not that one!

0:27:330:27:34

Bogeys!

0:27:450:27:46

It went right through me!

0:27:530:27:55

-Don't wobble it!

-I'm not doing anything!

-Just stand still, then!
