Operation Ouch. | 0:00:20 | 0:00:22 | |
'He is Dr Chris.' | 0:00:23 | 0:00:26 | |
'He's Dr Xand. | 0:00:26 | 0:00:28 | |
'And yes, we're twins. | 0:00:28 | 0:00:30 | |
'Do you know how brilliant your body really is?' | 0:00:30 | 0:00:33 | |
I'm getting better. | 0:00:33 | 0:00:34 | |
'Well, we're going to show you.' | 0:00:34 | 0:00:36 | |
Oh, there you go. | 0:00:36 | 0:00:38 | |
'In this series, we'll be pushing our bodies to their limits.' | 0:00:38 | 0:00:41 | |
Hello. | 0:00:41 | 0:00:43 | |
'By doing extraordinary experiments on each other... ' | 0:00:43 | 0:00:45 | |
This is my sick. | 0:00:45 | 0:00:47 | |
'.To uncover what goes on inside...' | 0:00:47 | 0:00:49 | |
Ooh, er, that just came out of my ear. | 0:00:49 | 0:00:51 | |
'..and out.' | 0:00:51 | 0:00:53 | |
Wow, that's amazing. | 0:00:53 | 0:00:54 | |
'From the bizarre...' | 0:00:54 | 0:00:56 | |
Can we get a sample of your snot? HE GROANS | 0:00:56 | 0:00:59 | |
'..to the incredible.' | 0:00:59 | 0:01:00 | |
So now I'm seeing things. | 0:01:00 | 0:01:02 | |
'It's time to find out what you're made of.' | 0:01:02 | 0:01:05 | |
Chris. Chris. Chris? | 0:01:05 | 0:01:07 | |
SIREN WAILS | 0:01:07 | 0:01:08 | |
Coming up today... | 0:01:08 | 0:01:11 | |
On Operation Ouch. | 0:01:11 | 0:01:12 | |
'We bare our teeth to see what happens when you don't brush.' | 0:01:15 | 0:01:19 | |
DR XAND GROANS | 0:01:19 | 0:01:22 | |
'This man reveals an amazing body. | 0:01:22 | 0:01:26 | |
'And prepare yourself for the wonders of wee.' | 0:01:26 | 0:01:29 | |
-It really smells in here. -Yes, it does. | 0:01:30 | 0:01:33 | |
'But first...' | 0:01:33 | 0:01:36 | |
Each year, over 18 million incidents mean people end up in | 0:01:36 | 0:01:39 | |
accident and emergency. | 0:01:39 | 0:01:41 | |
Let's see how the team fix our first patient. | 0:01:41 | 0:01:44 | |
'In accident and emergency, four-year-old Didi has | 0:01:46 | 0:01:49 | |
'come in with his mum and dad because he's in a bit of a fix.' | 0:01:49 | 0:01:52 | |
-(UNCLEARLY) -I tried to push something up my nose. | 0:01:52 | 0:01:55 | |
'Say what?' | 0:01:55 | 0:01:57 | |
I got a call to say he's got a screw up his nose. | 0:01:57 | 0:02:01 | |
'It's a toy screw, right?' | 0:02:01 | 0:02:03 | |
No, it's not a toy one. It's an actual screw, yeah. | 0:02:03 | 0:02:06 | |
'I see. | 0:02:06 | 0:02:08 | |
'So how on earth did the screw get up there?' | 0:02:08 | 0:02:11 | |
'Didi and his friend were sitting on a mat at school. | 0:02:14 | 0:02:16 | |
'Nice mat.' | 0:02:16 | 0:02:18 | |
'And there was a screw on the mat. | 0:02:18 | 0:02:20 | |
'Didi loved the look of that screw but so did his friend.' | 0:02:20 | 0:02:24 | |
'What's the big deal? It's just a screw.' | 0:02:24 | 0:02:26 | |
'It's not just a screw, Xand. | 0:02:26 | 0:02:28 | |
'It has a purpose and Didi knew what he had to do.' | 0:02:28 | 0:02:31 | |
'Repair that desk?' | 0:02:31 | 0:02:33 | |
'No.' | 0:02:33 | 0:02:34 | |
'Fix that squeaky window?' | 0:02:34 | 0:02:36 | |
'No, Xand. He picked up that screw...' | 0:02:36 | 0:02:39 | |
'I'm on the end of my seat. What did he do?' | 0:02:39 | 0:02:41 | |
'He put it up his nose because...it fitted.' | 0:02:41 | 0:02:44 | |
'Oh, bad idea.' | 0:02:44 | 0:02:46 | |
'Yep, and now it's stuck up there and won't come out.' | 0:02:46 | 0:02:49 | |
'Ouch.' | 0:02:49 | 0:02:51 | |
'From the look of him, you wouldn't guess there was a big screw | 0:02:51 | 0:02:55 | |
'firmly lodged up his left nostril but there is. | 0:02:55 | 0:02:59 | |
'Now it's over to Dr Mashhood Qazi to get it out.' | 0:02:59 | 0:03:02 | |
-And, Mum, has he done this before? -No! He hasn't. | 0:03:03 | 0:03:06 | |
Am I going to find some gold? | 0:03:06 | 0:03:09 | |
'No, Doc, there's no gold. It's just a screw.' | 0:03:09 | 0:03:12 | |
Let me see. | 0:03:12 | 0:03:14 | |
'Dr Mashhood has a look up Didi's nose to see | 0:03:14 | 0:03:17 | |
'where the screw is hiding.' | 0:03:17 | 0:03:19 | |
OK. | 0:03:19 | 0:03:20 | |
Didi's done a terrific job. | 0:03:20 | 0:03:22 | |
He's got a big screw up his nose, which we need to take out, | 0:03:22 | 0:03:27 | |
seriously, otherwise it's going to cause a lot of problems. | 0:03:27 | 0:03:30 | |
'So to get that screw out, | 0:03:30 | 0:03:32 | |
'the doctor uses a pair of medical tweezers. | 0:03:32 | 0:03:35 | |
'This might look uncomfortable but if the screw doesn't come out, | 0:03:35 | 0:03:38 | |
'it could damage Didi's nose and cause an infection.' | 0:03:38 | 0:03:41 | |
'But it won't budge, so Dr Mashhood changes tack.' | 0:03:41 | 0:03:45 | |
SHE BLOWS AIR | 0:03:47 | 0:03:49 | |
'Didi's mum blocks his right nostril then blows into his mouth to | 0:03:49 | 0:03:53 | |
'try and push the screw back down the left one. | 0:03:53 | 0:03:56 | |
'But still no luck. | 0:03:56 | 0:03:58 | |
'So after two failed attempts and the screw wedged well | 0:03:59 | 0:04:03 | |
'and truly up there, there's only one option left - an operation. | 0:04:03 | 0:04:08 | |
'We'll be back later to see how Didi gets on.' | 0:04:08 | 0:04:11 | |
'And now to our lab... | 0:04:16 | 0:04:18 | |
Whoa. | 0:04:18 | 0:04:20 | |
'..where we do incredible experiments.' | 0:04:20 | 0:04:22 | |
Ugh, it's disgusting. | 0:04:22 | 0:04:23 | |
'To show you how your body works.' | 0:04:23 | 0:04:25 | |
It's not pretty to look at but it is brilliant stuff. | 0:04:25 | 0:04:28 | |
'Just don't try anything you see here at home.' | 0:04:28 | 0:04:31 | |
Take a look at this. | 0:04:31 | 0:04:33 | |
It's a skull that's over 100 years old. | 0:04:34 | 0:04:37 | |
Now, it's from a five-year-old, but look carefully | 0:04:37 | 0:04:40 | |
and you'll see why I really wanted to show it to you. | 0:04:40 | 0:04:43 | |
'This skull has two sets of teeth. These are milk teeth. | 0:04:43 | 0:04:49 | |
'And these are the adult teeth. | 0:04:49 | 0:04:51 | |
'They're waiting to come through when the milk teeth fall out. | 0:04:51 | 0:04:55 | |
'But what's amazing about this, is that it's not amazing at all.' | 0:04:55 | 0:04:59 | |
If you're still waiting for your adult teeth, just think, | 0:04:59 | 0:05:02 | |
they're already in your head fully grown. | 0:05:02 | 0:05:05 | |
Underneath your skin, your skull will look just like this one. | 0:05:05 | 0:05:09 | |
Both sets of teeth are coated with enamel. | 0:05:09 | 0:05:12 | |
It's the hardest substance in your body. | 0:05:12 | 0:05:14 | |
It's even harder than bone but it's not indestructible. | 0:05:14 | 0:05:17 | |
As we're about to find out. | 0:05:17 | 0:05:19 | |
HE BREATHES | 0:05:23 | 0:05:25 | |
DR XAND GASPS AND GROANS | 0:05:25 | 0:05:27 | |
-Does my breath smell bad? -Yes, it does actually. | 0:05:27 | 0:05:30 | |
I'm not surprised. I haven't brushed my teeth in two days. | 0:05:30 | 0:05:33 | |
But it's all for a good cause. Isn't it, Chris? | 0:05:33 | 0:05:36 | |
I hope so. | 0:05:36 | 0:05:38 | |
'In fact, it was my idea. | 0:05:38 | 0:05:40 | |
'Whilst I've been brushing my teeth twice a day, as you should, | 0:05:40 | 0:05:44 | |
'I haven't let Chris brush his at all for two days. | 0:05:44 | 0:05:47 | |
'But it's all in the name of medical research.' | 0:05:47 | 0:05:50 | |
My teeth feel fuzzy. | 0:05:50 | 0:05:52 | |
That's because Chris has a layer of plaque building up on them. | 0:05:52 | 0:05:56 | |
Open wide. | 0:05:56 | 0:05:57 | |
'I'm going to show you why plaque isn't something you want a lot of. | 0:05:57 | 0:06:01 | |
'When you go to the dentist, you'll have had your teeth | 0:06:01 | 0:06:04 | |
'scraped like this.' | 0:06:04 | 0:06:06 | |
-Going anywhere nice on holiday this year, Chris? -No. | 0:06:06 | 0:06:09 | |
Oh lovely, I've been there. It's wonderful at this time of year. | 0:06:09 | 0:06:12 | |
Ugh, Chris, this is disgusting. | 0:06:12 | 0:06:15 | |
Plaque is a mixture of food particles, acid and bacteria. | 0:06:17 | 0:06:21 | |
We've all got thousands of different bacteria living in our mouths | 0:06:21 | 0:06:25 | |
and most of them are harmless but there are some bad ones that | 0:06:25 | 0:06:28 | |
can turn the sugars in the food we eat into acid. | 0:06:28 | 0:06:31 | |
'And it's this plaque acid that's the real problem.' | 0:06:31 | 0:06:35 | |
It eats away at the tooth enamel and that's what tooth decay is. | 0:06:35 | 0:06:38 | |
Please can I have my toothbrush back now? | 0:06:38 | 0:06:41 | |
Soon. There's more to show you. | 0:06:41 | 0:06:43 | |
'We're both going to rinse our mouths with a special blue dye | 0:06:43 | 0:06:47 | |
'that will show up how much plaque we have on our teeth. | 0:06:47 | 0:06:51 | |
'It's my brushed gnashers first. | 0:06:51 | 0:06:53 | |
'Ta-da.' | 0:06:53 | 0:06:55 | |
-You look really funny. -You look funny. | 0:06:55 | 0:06:58 | |
'Now even though Xand has been brushing regularly, | 0:06:58 | 0:07:01 | |
'you can see some dye has stuck to his teeth and that's all plaque.' | 0:07:01 | 0:07:05 | |
That makes me a bit worried | 0:07:05 | 0:07:06 | |
cos I haven't brushed my teeth for over two days. | 0:07:06 | 0:07:09 | |
-Ugh, why did you do that? -It was your idea. | 0:07:09 | 0:07:11 | |
'Well, after a quick rinse with the blue dye it's time to | 0:07:14 | 0:07:18 | |
'check out the state of my un-brushed teeth.' | 0:07:18 | 0:07:21 | |
Ugh, there's plaque everywhere. How did you let this happen? | 0:07:21 | 0:07:28 | |
RECORD SCRATCH | 0:07:28 | 0:07:30 | |
So if you compare my lovely clean brushed teeth with Chris's | 0:07:30 | 0:07:34 | |
disgusting, un-brushed teeth, you can really see the difference. | 0:07:34 | 0:07:38 | |
And all that plaque has built up in just two days. | 0:07:38 | 0:07:41 | |
That's gross. | 0:07:41 | 0:07:42 | |
-I feel quite disgusting. I would like my toothbrush back. -No. | 0:07:42 | 0:07:46 | |
'I want to get a much closer look at your plaque, Chris, | 0:07:46 | 0:07:49 | |
'which is why I've put a dollop of it under this microscope.' | 0:07:49 | 0:07:53 | |
-Look at this. -Wow. | 0:07:53 | 0:07:56 | |
So these bacteria are the ones that live in my plaque | 0:07:56 | 0:07:59 | |
and although we can't tell which are the good ones | 0:07:59 | 0:08:02 | |
and which are the bad ones, some of them | 0:08:02 | 0:08:04 | |
are the ones that produce the acid that is rotting my teeth right now. | 0:08:04 | 0:08:08 | |
Yep, and if you just leave plaque it hardens like cement. | 0:08:08 | 0:08:11 | |
That's called tartar, and it builds and builds. | 0:08:11 | 0:08:15 | |
It can damage your gums and give you rotting teeth that look like this. | 0:08:15 | 0:08:20 | |
Not a good look. | 0:08:21 | 0:08:23 | |
That's it, I've had enough. I am going to brush my teeth. | 0:08:23 | 0:08:27 | |
No, he's not. | 0:08:27 | 0:08:28 | |
The kitchen. For you, it may be the best room in the house | 0:08:35 | 0:08:38 | |
with its stainless steel work surfaces, | 0:08:38 | 0:08:40 | |
its fancy oven with two kinds of heat | 0:08:40 | 0:08:43 | |
and top-of-the-range refrigerator stocked full of goodies. | 0:08:43 | 0:08:47 | |
But the kitchen can also be a place of danger. | 0:08:47 | 0:08:50 | |
-Can't it, Xand? -Yes. | 0:08:51 | 0:08:54 | |
Is that a fake comedy knife? | 0:08:54 | 0:08:56 | |
Yes. | 0:08:56 | 0:08:58 | |
Good, because knives can be dangerous and could cause a bad cut. | 0:08:58 | 0:09:02 | |
Is that a comedy fake hand? | 0:09:06 | 0:09:07 | |
Yes. | 0:09:07 | 0:09:09 | |
Good, because we need safety in the kitchen at all times. | 0:09:09 | 0:09:12 | |
Now let's relax with a nice cup of tea. | 0:09:12 | 0:09:14 | |
Ooh, I'll get it. KETTLE WHISTLES | 0:09:14 | 0:09:16 | |
Isn't that nice of him? | 0:09:16 | 0:09:18 | |
Ooh, hold on. The water, it's boiling... | 0:09:18 | 0:09:20 | |
-DR XAND SCREAMS -Hot. | 0:09:20 | 0:09:22 | |
Xand, is that a comedy burnt finger? | 0:09:24 | 0:09:26 | |
No, it's a minor injury. | 0:09:26 | 0:09:29 | |
'So what should you do if you get a burn? | 0:09:33 | 0:09:36 | |
'Should you - A - hop up and down and tap it with a wand? | 0:09:36 | 0:09:39 | |
'B - ask it politely to stop hurting? | 0:09:40 | 0:09:43 | |
'C - run it under cold water?' | 0:09:44 | 0:09:48 | |
'Oh, I do like magic, I hope it's option A.' | 0:09:48 | 0:09:50 | |
The answer is C. | 0:09:52 | 0:09:55 | |
'So to treat a burn...' | 0:09:57 | 0:09:59 | |
Run it under the cold tap as quickly as possible | 0:09:59 | 0:10:01 | |
and keep it there for a good ten minutes to cool the burn down. | 0:10:01 | 0:10:04 | |
Right, job done. | 0:10:04 | 0:10:06 | |
-Oh, can we have that cup of tea now? -Yeah, come on. | 0:10:06 | 0:10:09 | |
LOUD TRUMP OF WIND | 0:10:12 | 0:10:14 | |
Was that a comedy whoopee cushion making that noise? | 0:10:14 | 0:10:17 | |
Yes. | 0:10:17 | 0:10:19 | |
WIND CONTINUES | 0:10:19 | 0:10:21 | |
'So remember, run a burn under a cold tap for ten minutes | 0:10:21 | 0:10:25 | |
'but if you're worried, tell an adult.' | 0:10:25 | 0:10:28 | |
'We've got some incredible body tricks | 0:10:32 | 0:10:34 | |
'for you to show your friends.' | 0:10:34 | 0:10:36 | |
'Want to find out how you can stop your mates from simply | 0:10:36 | 0:10:39 | |
'picking up something off the floor?' | 0:10:39 | 0:10:41 | |
'We're going to show you.' | 0:10:41 | 0:10:43 | |
-Xand, to do this trick, I'm going to need some money. -Oh, all right. | 0:10:43 | 0:10:46 | |
It's my lunch money. I'm going to need it back. | 0:10:46 | 0:10:49 | |
Well, I tell you what, you can have it back | 0:10:49 | 0:10:51 | |
if you can pick it up off the floor. If you don't pick it up, I get it. | 0:10:51 | 0:10:55 | |
Sounds quite easy. | 0:10:55 | 0:10:56 | |
Got it. That was a rubbish trick. Who thinks that was a rubbish trick? | 0:10:59 | 0:11:03 | |
KIDS: Me. | 0:11:03 | 0:11:05 | |
All right, well, we'll do it again. | 0:11:05 | 0:11:07 | |
This time you won't be able to pick up the money. | 0:11:07 | 0:11:09 | |
So go and stand against the wall. | 0:11:09 | 0:11:11 | |
Now, keeping your feet where they are, | 0:11:11 | 0:11:13 | |
I just want you to bend down to pick up the money. | 0:11:13 | 0:11:16 | |
Come on, Xand, pick it up. | 0:11:17 | 0:11:19 | |
Chris, what have you done? | 0:11:19 | 0:11:21 | |
Ah, I can't get it. | 0:11:21 | 0:11:24 | |
That's hard. | 0:11:24 | 0:11:25 | |
So it looks like I get the lunch money, doesn't it? | 0:11:25 | 0:11:28 | |
KIDS BOO | 0:11:28 | 0:11:30 | |
'Come on, then, let's see if anyone else can do it. | 0:11:33 | 0:11:36 | |
'He can't. | 0:11:38 | 0:11:39 | |
'She definitely can't. | 0:11:41 | 0:11:44 | |
'So why can't anyone, including Xand, pick up the money?' | 0:11:45 | 0:11:49 | |
When you bend over, your bum pushes back | 0:11:49 | 0:11:51 | |
and the wall's stopping it from pushing back. | 0:11:51 | 0:11:55 | |
'George has got it. | 0:11:55 | 0:11:57 | |
'Normally when you bend over to pick something up, your body will | 0:11:57 | 0:12:01 | |
'adjust itself backwards in order to balance it out. | 0:12:01 | 0:12:06 | |
'So when your body's flat against the wall, you can't go backwards | 0:12:06 | 0:12:09 | |
'and there's no chance of picking up that money. | 0:12:09 | 0:12:12 | |
'All you can do is fall forwards.' | 0:12:12 | 0:12:14 | |
So I'm going to need the money back from all of you guys. | 0:12:14 | 0:12:18 | |
KIDS SHOUT | 0:12:18 | 0:12:19 | |
Give my money back! Come on, Xand. | 0:12:19 | 0:12:21 | |
Remember Didi who had a screw lodged up his nose? | 0:12:27 | 0:12:29 | |
Let's head back to accident and emergency | 0:12:29 | 0:12:31 | |
to find out how he's getting on. | 0:12:31 | 0:12:33 | |
'Back in Manchester, four-year-old Didi is in hospital with | 0:12:35 | 0:12:39 | |
'a large screw wedged up his nose. | 0:12:39 | 0:12:42 | |
'He'd been playing with his friend | 0:12:43 | 0:12:45 | |
'when they saw a shiny screw on the mat. | 0:12:45 | 0:12:48 | |
'Didi loved the look of that screw but so did his friend. | 0:12:48 | 0:12:51 | |
'They both wanted that screw | 0:12:51 | 0:12:53 | |
'and it was at this point Didi came up with a great idea. | 0:12:53 | 0:12:56 | |
'He picked the screw up and hid it up his nose. | 0:12:56 | 0:12:59 | |
'Only it wouldn't come out again | 0:12:59 | 0:13:01 | |
'and it's evaded all attempts to catch it.' | 0:13:01 | 0:13:04 | |
'So now it's over to the surgical team to get that screw loose. | 0:13:05 | 0:13:09 | |
'Didi's had a general anaesthetic to put him to sleep. | 0:13:09 | 0:13:12 | |
'This means the surgical team can delve deeper into his nose | 0:13:12 | 0:13:16 | |
'and pull the hiding screw out without him feeling a thing. | 0:13:16 | 0:13:20 | |
'So here goes. | 0:13:20 | 0:13:22 | |
'With Didi totally still, it's not long before the surgeon | 0:13:24 | 0:13:28 | |
'catches up with that screw. | 0:13:28 | 0:13:30 | |
'At last, it's out. | 0:13:32 | 0:13:34 | |
-It's big. -'Yep, it's a whopper.' | 0:13:37 | 0:13:39 | |
How did he manage to get it up his nose? | 0:13:39 | 0:13:41 | |
'Who knows? But a couple of hours later | 0:13:41 | 0:13:43 | |
'and Didi has come around from his operation to the good news.' | 0:13:43 | 0:13:47 | |
That was in my nose cos I was pushing it in. | 0:13:47 | 0:13:51 | |
'Well hopefully nothing will be going up your nostrils | 0:13:51 | 0:13:54 | |
'in the future. | 0:13:54 | 0:13:56 | |
'And with his conk clear, he's off home.' | 0:13:56 | 0:13:58 | |
'Bye.' | 0:13:59 | 0:14:01 | |
'Still to come... | 0:14:05 | 0:14:07 | |
'Xand's got a foot that needs freezing. | 0:14:07 | 0:14:09 | |
'Evie's got a gash that needs gluing.' | 0:14:10 | 0:14:13 | |
'And I've got wee with secret powers.' | 0:14:14 | 0:14:17 | |
That really works well. | 0:14:18 | 0:14:21 | |
'Now, did you know that the average eyebrow has 450 hairs?' | 0:14:21 | 0:14:25 | |
'Wow, that's amazing. And so's this. | 0:14:25 | 0:14:30 | |
'On an ordinary street. | 0:14:32 | 0:14:34 | |
'In an ordinary house. | 0:14:35 | 0:14:37 | |
'One man is getting ready for his day. | 0:14:39 | 0:14:42 | |
'Nice towel. | 0:14:42 | 0:14:43 | |
'Lovely. | 0:14:43 | 0:14:44 | |
'He likes a blow dry, then? | 0:14:46 | 0:14:48 | |
'Hang on a minute. Is he drying his face?' | 0:14:48 | 0:14:51 | |
'Oh, yes. Check this out! | 0:14:51 | 0:14:53 | |
'Meet Jesus Aceves. He has an amazing body. | 0:14:58 | 0:15:02 | |
'Jesus has over 60,000 hairs on his face. | 0:15:02 | 0:15:07 | |
'This is no more than the average man | 0:15:07 | 0:15:09 | |
'but whereas we will have tiny, fine facial hairs, | 0:15:09 | 0:15:12 | |
'incredibly Jesus' hairs are long and dark like the hair on his head. | 0:15:12 | 0:15:17 | |
'So what makes his amazing body like this? | 0:15:17 | 0:15:20 | |
'Well, Jesus has had his hairy face since birth | 0:15:20 | 0:15:24 | |
'and it's down to a genetic condition called hypertrichosis. | 0:15:24 | 0:15:27 | |
'Before we're born, we're all covered with a layer of fine hair | 0:15:29 | 0:15:32 | |
'which normally disappears about a month before we burst out | 0:15:32 | 0:15:35 | |
'but hypertrichosis means the hair continues to | 0:15:35 | 0:15:38 | |
'grow in unexpected places. | 0:15:38 | 0:15:40 | |
'His furry face keeps him toasty warm in winter and come summertime | 0:15:42 | 0:15:46 | |
'he treats his luscious locks to a trim to keep himself cool. | 0:15:46 | 0:15:51 | |
'Jesus is one of only 50 people in the world who have | 0:15:52 | 0:15:56 | |
'super hairy faces. | 0:15:56 | 0:15:59 | |
'Now that's amazing.' | 0:15:59 | 0:16:01 | |
'Your body can need mending in all sorts of ways and | 0:16:09 | 0:16:11 | |
'we're going to meet some special teams that are trained to fix you.' | 0:16:11 | 0:16:15 | |
SHE LAUGHS | 0:16:15 | 0:16:17 | |
'This is Rocco. | 0:16:17 | 0:16:19 | |
'He's come to see a foot doctor today, and so have I.' | 0:16:19 | 0:16:22 | |
Take a look at my feet. | 0:16:22 | 0:16:24 | |
They look OK, don't they, in a sort of foot-ish way. But look closer. | 0:16:24 | 0:16:29 | |
'Meet my verrucas. | 0:16:29 | 0:16:31 | |
'We've actually become quite attached.' | 0:16:31 | 0:16:34 | |
Verrucas are caused by a virus - the human papillomavirus. | 0:16:34 | 0:16:37 | |
They're rough mounds of skin that grow on the bottom | 0:16:37 | 0:16:40 | |
of your feet where it's nice and warm. | 0:16:40 | 0:16:43 | |
'I've had these ones for a while.' | 0:16:43 | 0:16:45 | |
But enough is enough. | 0:16:45 | 0:16:46 | |
'This is Nutan Shah. | 0:16:48 | 0:16:51 | |
'A podiatrist, or foot doctor, at the London Podiatry Centre. | 0:16:51 | 0:16:54 | |
'She knows everything about verrucas.' | 0:16:54 | 0:16:57 | |
Why do they stick around so long? | 0:16:57 | 0:17:00 | |
They like warm, dark, moist places, | 0:17:00 | 0:17:02 | |
so your foot is an ideal place for it to live in. | 0:17:02 | 0:17:05 | |
Basically the verrucas are saying my foot's good? | 0:17:05 | 0:17:08 | |
-It's like a five-star hotel. -HE LAUGHS | 0:17:08 | 0:17:10 | |
'Well it's time for these guests to check out. | 0:17:10 | 0:17:13 | |
'First, Nutan has to cut off all the dead hard skin.' | 0:17:15 | 0:17:19 | |
This bit doesn't hurt at all. | 0:17:19 | 0:17:20 | |
It's slightly ticklish but it's actually quite pleasant. | 0:17:20 | 0:17:23 | |
So long, verruca! | 0:17:23 | 0:17:26 | |
'Now my foot's going to get frozen. | 0:17:26 | 0:17:29 | |
'This is liquid nitrogen which helps kill off the virus.' | 0:17:29 | 0:17:34 | |
Now it is quite painful. It stings. | 0:17:34 | 0:17:37 | |
'Liquid nitrogen is extremely cold. | 0:17:37 | 0:17:40 | |
'Minus 200 degrees centigrade, to be precise. | 0:17:40 | 0:17:43 | |
'That's at least ten times colder than your freezer at home. | 0:17:43 | 0:17:47 | |
'And with a few treatments, your verrucas are no more. | 0:17:47 | 0:17:50 | |
'With the freezing over, Nutan puts silver nitrate on. | 0:17:51 | 0:17:55 | |
'It stops any blistering and also helps kill the virus.' | 0:17:55 | 0:17:58 | |
What we do is, we just rub it on to the area | 0:17:58 | 0:18:01 | |
and eventually it will go black. | 0:18:01 | 0:18:04 | |
'Like Rocco's. He's already had a few verruca treatments.' | 0:18:04 | 0:18:09 | |
How do verrucas feel on your foot? Do you notice them? | 0:18:09 | 0:18:12 | |
At first, when I used to step on the ground without | 0:18:12 | 0:18:15 | |
any shoes, it really started hurting me. | 0:18:15 | 0:18:17 | |
Cos that's what I noticed, with shoes on, it's not really a problem. | 0:18:17 | 0:18:21 | |
'It's important to remember that this virus is contagious. | 0:18:21 | 0:18:24 | |
'So don't touch it. | 0:18:24 | 0:18:25 | |
'Don't pick it and make sure you don't walk around anywhere | 0:18:25 | 0:18:29 | |
'barefoot, or you'll spread it. | 0:18:29 | 0:18:31 | |
'Now, brace yourself, Rocco, here comes the liquid nitrogen.' | 0:18:32 | 0:18:36 | |
HE GASPS | 0:18:36 | 0:18:38 | |
'Yep, takes your breath away.' | 0:18:38 | 0:18:40 | |
You've got a really good technique. | 0:18:40 | 0:18:42 | |
-Like you're just laughing through it, right? -Yeah. | 0:18:42 | 0:18:44 | |
'So, freezing over, there's a coat of silver nitrate. | 0:18:44 | 0:18:49 | |
'And we're both all done.' | 0:18:49 | 0:18:51 | |
If you've got a verruca that won't go away, people like Nutan | 0:18:51 | 0:18:55 | |
are here to help. But remember, lots of verrucas do go away on their own. | 0:18:55 | 0:18:59 | |
It might just take a while. | 0:18:59 | 0:19:00 | |
So, in the meantime, why not give it a name? | 0:19:00 | 0:19:03 | |
Mine's called Dr Chris. | 0:19:03 | 0:19:05 | |
Just don't tell him. | 0:19:05 | 0:19:06 | |
When you get injured, your body is brilliant at mending itself. | 0:19:10 | 0:19:14 | |
This next boy should know, he's always having accidents. | 0:19:14 | 0:19:18 | |
# If there's a bone to break he'll break it | 0:19:18 | 0:19:21 | |
# If there's a wound to graze, he'll graze it | 0:19:21 | 0:19:24 | |
# If there's an ankle to sprain, he'll sprain it | 0:19:24 | 0:19:26 | |
# He's the unluckiest kid. # | 0:19:26 | 0:19:28 | |
'Look out for that squirrel. | 0:19:31 | 0:19:32 | |
LOUD CRASH | 0:19:32 | 0:19:34 | |
'When you break your arm, it's called a fracture. | 0:19:34 | 0:19:36 | |
'And it gets put in plaster to keep it in place. | 0:19:36 | 0:19:39 | |
'But underneath, the real fixing is done by you.' | 0:19:39 | 0:19:42 | |
'Wow.' | 0:19:42 | 0:19:43 | |
'Your broken bone leaks blood and it contains special building blocks, | 0:19:43 | 0:19:47 | |
'including fibres from proteins called collagen and cartilage. | 0:19:47 | 0:19:51 | |
'They build a temporary bridge called a callous | 0:19:55 | 0:19:59 | |
'and it stays in place for about three weeks. | 0:19:59 | 0:20:02 | |
'Then a specialist team called the osteoblasts move in. | 0:20:02 | 0:20:06 | |
'These are cells that make tiny bits of bone that set like cement.' | 0:20:06 | 0:20:10 | |
'After a few weeks, your bones have repaired themselves. | 0:20:10 | 0:20:13 | |
'Your cast will be off and you're as good as new. | 0:20:13 | 0:20:16 | |
'Just watch out for squirrels.' | 0:20:16 | 0:20:18 | |
'Uh-oh. Oh, dear!' | 0:20:18 | 0:20:20 | |
# He's the unluckiest kid. # | 0:20:20 | 0:20:22 | |
Now sometimes on Operation Ouch what we really... | 0:20:22 | 0:20:25 | |
What are you doing? | 0:20:25 | 0:20:27 | |
-I'm holding it in. -Why didn't you go before I started? | 0:20:27 | 0:20:30 | |
-Because I need it for this week's Investigation Ouch. -Oh. | 0:20:30 | 0:20:33 | |
Now, I know what you're thinking. | 0:20:41 | 0:20:43 | |
You should have flushed the toilet, Dr Chris. | 0:20:43 | 0:20:46 | |
Well, you're wrong. I didn't use the toilet. | 0:20:46 | 0:20:50 | |
But I am going to wash my hands. | 0:20:50 | 0:20:51 | |
'I'm actually taking my wee to Bristol.' | 0:20:53 | 0:20:56 | |
It's here somewhere. Can you get out the map? | 0:20:56 | 0:20:59 | |
'Because apparently it contains hidden powers.' | 0:20:59 | 0:21:02 | |
This is the Bristol Robotics Laboratory | 0:21:04 | 0:21:06 | |
and some scientists here have decided that, rather than | 0:21:06 | 0:21:09 | |
flushing their wee down the toilets, they're going to use it as a power | 0:21:09 | 0:21:12 | |
source, and that's why I've brought mine all the way from London. | 0:21:12 | 0:21:16 | |
I suppose I could've just gone when I got here. | 0:21:16 | 0:21:19 | |
Come on, wee-wee. | 0:21:23 | 0:21:25 | |
'We're off to meet Dr Ioannis Ieropoulous. | 0:21:26 | 0:21:29 | |
'He's the brains behind pee power.' | 0:21:29 | 0:21:32 | |
So, Ioannis, I've got something for you. | 0:21:32 | 0:21:34 | |
-Oh, wow. Thank you very much, Chris. -It's my pleasure. | 0:21:34 | 0:21:37 | |
The first thing to say about being here is it really smells in here. | 0:21:37 | 0:21:41 | |
Yes, it does. | 0:21:41 | 0:21:43 | |
It's basically a bit like, imagine instead of leaving | 0:21:43 | 0:21:45 | |
your classroom to go and pee, everyone just peed on the floor. | 0:21:45 | 0:21:48 | |
That's a bit like what it smells like. | 0:21:48 | 0:21:51 | |
But you're putting the wee here to slightly better use, aren't you? | 0:21:51 | 0:21:54 | |
Yes. So we use urine as a fuel for electricity. | 0:21:54 | 0:21:58 | |
'Yep, you heard right. They're turning wee into electricity.' | 0:22:00 | 0:22:04 | |
So how do you do that? | 0:22:05 | 0:22:06 | |
So we will take this urine | 0:22:06 | 0:22:09 | |
and we will add it into microbial fuel cells which are something like | 0:22:09 | 0:22:14 | |
batteries, only they have living micro-organisms inside, living bugs. | 0:22:14 | 0:22:18 | |
'The bugs living in the microbial fuel cells, or batteries, | 0:22:18 | 0:22:22 | |
'feed on the sugars and proteins in urine, breaking it down. | 0:22:22 | 0:22:26 | |
'And this process creates electricity. | 0:22:26 | 0:22:28 | |
'In fact, this four litres of wee could create enough power for | 0:22:31 | 0:22:34 | |
'20 minutes of talk time on a mobile phone, | 0:22:34 | 0:22:37 | |
'but that's not all it can do. | 0:22:37 | 0:22:39 | |
'Time to see my wee in action.' | 0:22:41 | 0:22:44 | |
So this is basically a battery, is that right? | 0:22:46 | 0:22:48 | |
-Yes, a very complicated one. -And what do you use it to power? | 0:22:48 | 0:22:52 | |
At the moment, we use it to power a remote controlled car. | 0:22:52 | 0:22:56 | |
-A remote controlled car? -Yeah. | 0:22:56 | 0:22:58 | |
That's quite cool, I love remote controlled cars. | 0:22:58 | 0:23:00 | |
'To get the car moving, we first need to top up the battery.' | 0:23:02 | 0:23:06 | |
So each one of these things that I'm putting the urine into | 0:23:06 | 0:23:09 | |
is a microbial fuel cell and there are bacteria in there | 0:23:09 | 0:23:12 | |
that are going to eat the sugars and proteins in the urine | 0:23:12 | 0:23:15 | |
and turn them into electricity which is then going to charge this car. | 0:23:15 | 0:23:19 | |
-HE LAUGHS -That really works well. | 0:23:24 | 0:23:26 | |
'At the moment, it takes a very large battery to power a | 0:23:26 | 0:23:30 | |
'very little car but hopefully, it won't be long before the batteries | 0:23:30 | 0:23:34 | |
'get smaller and the things they can power get bigger.' | 0:23:34 | 0:23:37 | |
Ioannis, so that is amazing. But what's the future? | 0:23:39 | 0:23:42 | |
Well, the future is about developing the technologies that can be | 0:23:42 | 0:23:45 | |
implemented into developing world countries and provide electricity. | 0:23:45 | 0:23:49 | |
It's basically one wonderful way of turning waste into something useful. | 0:23:49 | 0:23:54 | |
'So hopefully one day urine will create power for people in | 0:23:56 | 0:23:59 | |
'developing countries to light their homes and cook their food with.' | 0:23:59 | 0:24:03 | |
Obviously this doesn't mean that you can go and pour urine into all | 0:24:03 | 0:24:06 | |
the electronic kit in your house and expect it to work. | 0:24:06 | 0:24:09 | |
That would be both incredibly dangerous and very, very smelly. | 0:24:09 | 0:24:12 | |
But what we have seen is that scientists have invented | 0:24:12 | 0:24:15 | |
a way of producing power from urine. | 0:24:15 | 0:24:17 | |
Now if they can only invent a way of getting rid of the smell. | 0:24:17 | 0:24:21 | |
Our next patient was expecting a normal day. | 0:24:26 | 0:24:29 | |
But she's ended up in accident and emergency. | 0:24:29 | 0:24:31 | |
Let's see her get fixed. | 0:24:31 | 0:24:33 | |
'In Sheffield accident and emergency, eight-year-old Evie has | 0:24:36 | 0:24:39 | |
'arrived with her mum and a rather nasty looking cut to her chin. | 0:24:39 | 0:24:43 | |
'Oh, catch that drip.' | 0:24:44 | 0:24:47 | |
It stings a lot. | 0:24:47 | 0:24:49 | |
'I bet it does. What on earth happened? | 0:24:49 | 0:24:52 | |
'She's in her wellies, is that a clue? Let's find out.' | 0:24:52 | 0:24:56 | |
'Evie lives on a farm. | 0:24:58 | 0:25:00 | |
'On a farm? What animals does she have?' | 0:25:00 | 0:25:02 | |
'She's got a pet donkey. Two sheep. Five horses. | 0:25:02 | 0:25:08 | |
'Three cats and two dogs. | 0:25:08 | 0:25:09 | |
'Awesome. So what happened to her chin?' | 0:25:09 | 0:25:12 | |
'Keep quiet and I'll tell you. | 0:25:12 | 0:25:15 | |
'It was snowing. | 0:25:15 | 0:25:16 | |
'Whoa, indeed it was.' | 0:25:16 | 0:25:18 | |
'Evie decided to go sledging. | 0:25:18 | 0:25:20 | |
'She was bombing down a hill. | 0:25:20 | 0:25:21 | |
'She's going very fast.' | 0:25:21 | 0:25:24 | |
'Yes. And then a huge gust of wind blew her sledge away.' | 0:25:24 | 0:25:27 | |
'Oh, no!' | 0:25:27 | 0:25:29 | |
'She landed face first and her chin scraped along the snow | 0:25:29 | 0:25:32 | |
'and gravel beneath until she stopped.' | 0:25:32 | 0:25:35 | |
'Ouch!' | 0:25:35 | 0:25:37 | |
The snow wasn't as thick as I thought it was. | 0:25:37 | 0:25:41 | |
'Never mind, here's Dr Suzanne Baron to take a look at that chin.' | 0:25:42 | 0:25:46 | |
Quite a gash this, actually. | 0:25:48 | 0:25:49 | |
-'I'll say. -Say what? | 0:25:49 | 0:25:51 | |
'That it's quite a gash, duh!' | 0:25:51 | 0:25:54 | |
She's got a medium-sized cut under her chin which will definitely | 0:25:55 | 0:25:59 | |
need some cleaning and bringing the edges back together again. | 0:25:59 | 0:26:02 | |
'So, first the mission is to give Evie's wound a good clean | 0:26:02 | 0:26:06 | |
'and get all the gravel out that they can see. | 0:26:06 | 0:26:09 | |
'The skin on our chin has five layers for a piece of grit | 0:26:09 | 0:26:12 | |
'to get lost in. | 0:26:12 | 0:26:14 | |
'The combination of skin, fat, fibrous tissue | 0:26:14 | 0:26:17 | |
'and blood cells surrounds our skull. | 0:26:17 | 0:26:19 | |
'When these layers are broken, dangerous infection can occur. | 0:26:19 | 0:26:22 | |
'So it's important that we get that bit of grit out of Evie's chin | 0:26:22 | 0:26:25 | |
'and close up the hole. | 0:26:25 | 0:26:29 | |
'There's one stubborn bit of grit that just won't budge. | 0:26:29 | 0:26:32 | |
'Step up Nurse Susan Musson, grit extractor extraordinaire. | 0:26:33 | 0:26:39 | |
'If you're squeamish, look away now | 0:26:39 | 0:26:41 | |
'because to get a grip on that gravel she's using a needle. | 0:26:41 | 0:26:45 | |
I use just the very end of the needle, | 0:26:45 | 0:26:47 | |
just to keep flicking it out. | 0:26:47 | 0:26:49 | |

'Good plan, Evie. You've got true grit.' | 0:27:14 | 0:27:17 | |
'Very funny, Chris. | 0:27:17 | 0:27:19 | |
'Bye.' | 0:27:19 | 0:27:20 | |
'Next time, I'm on an emergency mission.' | 0:27:23 | 0:27:26 | |
There isn't any time to lose. | 0:27:26 | 0:27:28 | |
We've got to get the blood where it's needed as quickly as possible. | 0:27:28 | 0:27:31 | |
'This guy reveals an amazing body skill. | 0:27:31 | 0:27:34 | |
'And find out what happens when you puke.' | 0:27:35 | 0:27:38 | |
