0:00:02 > 0:00:05They've survived in some of the most extreme places on the planet -
0:00:05 > 0:00:07the tops of mountains,
0:00:07 > 0:00:09the highest seas,
0:00:09 > 0:00:10the deepest jungles,
0:00:10 > 0:00:13the hottest deserts,
0:00:13 > 0:00:15and the frozen Arctic.
0:00:16 > 0:00:18But these are not hardened adventurers.
0:00:18 > 0:00:20They're children, aged just 12 to 15,
0:00:20 > 0:00:23who've become Serious Explorers for CBBC.
0:00:23 > 0:00:25Oh, my gosh!
0:00:25 > 0:00:27In this Survival Special,
0:00:27 > 0:00:30we'll be looking at how they coped in the awful conditions.
0:00:30 > 0:00:32It hurts so bad!
0:00:32 > 0:00:33From their triumphs...
0:00:33 > 0:00:37I feel like the biggest man in the WORLD!
0:00:37 > 0:00:38..to their occasional slip-ups.
0:00:38 > 0:00:41Oh, no! Oh!
0:00:41 > 0:00:45And we'll be guiding you through our top tips for successful adventure.
0:00:45 > 0:00:47I'm the Serious Expedition leader, Ben Major.
0:00:47 > 0:00:49And I'm the assistant leader, Polly Murray.
0:00:49 > 0:00:52Stand by as we reveal the secrets of Serious Survival.
0:00:55 > 0:00:58Surviving in extreme environments takes guts and courage,
0:00:58 > 0:01:01but also lots of planning and experience.
0:01:01 > 0:01:04So don't try ANYTHING in this programme
0:01:04 > 0:01:06unless you're with experts like us.
0:01:06 > 0:01:09Between them, Ben and Polly have been on expeditions
0:01:09 > 0:01:12to some of the most extreme places on earth.
0:01:12 > 0:01:15As a survival specialist and ex-Army officer,
0:01:15 > 0:01:19Ben has had to live rough for weeks in jungles and deserts.
0:01:19 > 0:01:21And Polly's the first Scottish woman
0:01:21 > 0:01:25to have climbed the world's highest peak, Mount Everest.
0:01:25 > 0:01:29Every extreme environment has its own particular hazards.
0:01:29 > 0:01:30I didn't think it'd be this hot!
0:01:30 > 0:01:33And Serious Adventurers have encountered most of them,
0:01:33 > 0:01:35from seasickness out in the ocean...
0:01:35 > 0:01:38Good effort, Harry. At least you got it in a bowl.
0:01:38 > 0:01:42..to altitude sickness high in the mountains.
0:01:42 > 0:01:45But there's one thing young adventurers worry about most.
0:01:45 > 0:01:48- Not sure about going to the toilet. - ..The toilet.
0:01:48 > 0:01:51- Going to the toilet in the bushes. - Going to the toilet in a hole!
0:01:56 > 0:01:59When you're at home, you don't even think about going to the loo.
0:01:59 > 0:02:02On an expedition, it's a different matter.
0:02:02 > 0:02:04Then you have to decide where you're going to go
0:02:04 > 0:02:06and how you're going to go.
0:02:06 > 0:02:09And make sure you don't mess up the environment for other people.
0:02:09 > 0:02:12On a beautiful, unspoilt mountain everything that goes up
0:02:12 > 0:02:15must come down, and that includes poo.
0:02:15 > 0:02:18Now, what we've got to help us are...
0:02:18 > 0:02:19- black bags.- Ohh!
0:02:19 > 0:02:23- Is he having a laugh?!- You need to double-bag it, these are quite thin.
0:02:23 > 0:02:25Oh, that's dirty!
0:02:25 > 0:02:28So the only thing that goes in here is solid.
0:02:28 > 0:02:31- Er, I'm not doing it.- Pop that on there, you've got a nice...
0:02:31 > 0:02:35A kind of nice little rest and you can squat over, yeah?
0:02:35 > 0:02:38- I'm not going!- And we'll collect it on the way down the mountain.
0:02:38 > 0:02:41It was a similar routine climbing the 20,000-foot
0:02:41 > 0:02:44Cotopaxi in the Andes.
0:02:44 > 0:02:48If you need to do a number two, this is what you do it in.
0:02:48 > 0:02:52This portable device. In here, then you put it in here.
0:02:52 > 0:02:54But the freezing conditions up Cotopaxi
0:02:54 > 0:02:58gave Josh other concerns about going to the toilet.
0:02:58 > 0:03:00Our urine dispenser...
0:03:00 > 0:03:01"Dispenser"?
0:03:01 > 0:03:04..is outside our body. Will we have trouble?
0:03:04 > 0:03:08- Oh, God!- You're talking about your willy, aren't you?
0:03:08 > 0:03:09- Yes.- "Urine dispenser"!
0:03:09 > 0:03:12"Urine dispenser". I've never heard it called that before.
0:03:12 > 0:03:15Will you have problems with it? Be clear.
0:03:15 > 0:03:17- Will it freeze? Will the urine freeze?- No.
0:03:19 > 0:03:22In the Arctic, the sub-zero temperatures meant
0:03:22 > 0:03:25the adventurers didn't want to go to the toilet at all.
0:03:25 > 0:03:28I have to reveal my bottom in -30!
0:03:28 > 0:03:30I hate using the toilet out here.
0:03:30 > 0:03:32There is no toilet, that's the thing.
0:03:32 > 0:03:35You just have to crouch down and do what you have to do,
0:03:35 > 0:03:37so I try and avoid it where possible.
0:03:37 > 0:03:40At the beginning, I said I'd do one a week, which I've already done.
0:03:40 > 0:03:43So I'm not to go again.
0:03:43 > 0:03:46But after saving it up, there was relief when they finally went.
0:03:46 > 0:03:48'It's day four.'
0:03:48 > 0:03:51And I've just been for my first poop.
0:03:53 > 0:03:55Oh, my God.
0:03:55 > 0:03:57So good!
0:03:57 > 0:04:00The best poop I've ever had.
0:04:00 > 0:04:04Whatever the expedition, toilet trips are trickier than at home.
0:04:04 > 0:04:07But you can make your life easier -
0:04:07 > 0:04:09here's our top five tips for going in the wild.
0:04:09 > 0:04:11Carry freezer bags.
0:04:11 > 0:04:16For those beautiful places where you must take EVERYTHING out.
0:04:16 > 0:04:18Be organised in the cold.
0:04:18 > 0:04:21You don't want to forget your loo paper
0:04:21 > 0:04:25and, at -20 degrees, get frostbite on your bum.
0:04:26 > 0:04:30Don't go near rivers. You may be polluting someone's drinking water.
0:04:32 > 0:04:35Burn used toilet paper. It's much more environmentally friendly.
0:04:36 > 0:04:40When you've got to go, you've got to go.
0:04:40 > 0:04:43Everyone's in the same boat, so DON'T hold it in.
0:04:43 > 0:04:47Serious Adventurers have had to deal with some very different
0:04:47 > 0:04:52extreme environments - from extreme heat in the Namibian desert...
0:04:52 > 0:04:54I'm sweating sitting here. I'm not doing anything.
0:04:54 > 0:04:56..to extreme cold in the Arctic.
0:04:56 > 0:04:58HER BREATH SHUDDERS
0:04:58 > 0:05:00H-hi-i.
0:05:00 > 0:05:04To stand a chance of surviving, you've got to have the right kit.
0:05:07 > 0:05:10The temperature in most freezers is about -18 degrees.
0:05:10 > 0:05:14And you may have found, from taking out oven chips or even ice cream,
0:05:14 > 0:05:17that you can feel it hurting your hands almost immediately.
0:05:17 > 0:05:20So imagine living in temperatures much, much colder than this -
0:05:20 > 0:05:25say -30, -40 degrees Celsius - day after day.
0:05:25 > 0:05:27That's what the Serious Arctic team had to cope with,
0:05:27 > 0:05:31so the right clothing was a matter of life and death.
0:05:31 > 0:05:35And not looking after it had serious consequences.
0:05:35 > 0:05:37IT CLINKS SOLIDLY
0:05:37 > 0:05:40That's what I've got to wear today. I'm not kidding.
0:05:40 > 0:05:43I mean, I could chop the ice up with this thing.
0:05:43 > 0:05:46I could scrape it! THEY LAUGH
0:05:46 > 0:05:49It's important to remember that when you're on expedition,
0:05:49 > 0:05:52the kit is for protection not for fashion,
0:05:52 > 0:05:55though everyone looked pretty good in their Andes horse-riding outfits.
0:05:55 > 0:05:58HE SINGS THE THEME FROM THE GOOD, THE BAD AND THE UGLY
0:05:58 > 0:06:00Well, perhaps with one exception.
0:06:00 > 0:06:03I'm loving these.
0:06:03 > 0:06:05You look like a gorilla-gram!
0:06:05 > 0:06:07BEN LAUGHS
0:06:07 > 0:06:08Wherever you travel to,
0:06:08 > 0:06:11we've got five top tips on dressing for extremes.
0:06:11 > 0:06:12Test it at home.
0:06:12 > 0:06:17You DO NOT want to be working out how to do up a zip at -40 degrees.
0:06:17 > 0:06:18Get the right boots.
0:06:18 > 0:06:21You need different boots for different environments.
0:06:21 > 0:06:24Make sure they're well worn-in and REALLY comfy.
0:06:24 > 0:06:25Use layers.
0:06:25 > 0:06:30In the cold, you need lots of layers to trap the air to keep you warm.
0:06:30 > 0:06:32Don't sweat in the freezing cold.
0:06:32 > 0:06:34Take layers off before you get too hot,
0:06:34 > 0:06:38otherwise, your sweat freezes and you get dangerously cold.
0:06:38 > 0:06:42Wear a hat. In the cold, it will keep you warm.
0:06:42 > 0:06:44And in the heat, it will keep you cool.
0:06:49 > 0:06:53If you're going to live rough, be prepared to share your home
0:06:53 > 0:06:56with the creatures that live there already.
0:06:56 > 0:07:00Spiders and tarantulas are never far away in the jungle.
0:07:00 > 0:07:03- Just to keep you happy... You're sleeping here?- Yeah.
0:07:03 > 0:07:07- See all these holes here? All spiders. All spider holes.- No!- OK?
0:07:07 > 0:07:10And that night, a local tarantula came out to play.
0:07:10 > 0:07:12Argh! Get it away!
0:07:12 > 0:07:16We were just sat down talking and Georgia spotted
0:07:16 > 0:07:19the most HUGE tarantula in the corner that I've seen before.
0:07:19 > 0:07:21It's on the FLOOR! ARGH!
0:07:21 > 0:07:23THEY SCREAM AND WHIMPER
0:07:23 > 0:07:26Get it away! No, Polly, seriously, put it outside!
0:07:26 > 0:07:29I hope nothing will get me, so I'll just stay like this.
0:07:29 > 0:07:32But it's a much smaller creature that can drive you mad.
0:07:32 > 0:07:36The mossies are absolutely terrible. They're flying EVERYWHERE.
0:07:36 > 0:07:39Flipping MOSQUITO in my ear!
0:07:39 > 0:07:42I can see about, literally, in this space here, about 100 or something.
0:07:42 > 0:07:44Oh, God, I'm getting bitten alive! Bleurgh!
0:07:44 > 0:07:46Ouch!
0:07:46 > 0:07:49I'm getting bitten now. I'm getting bitten! Blubluble!
0:07:50 > 0:07:52Sheesh! Stupid little things!
0:07:53 > 0:07:56But they can also cause more serious problems.
0:07:56 > 0:07:59For Chanelle, an allergy to mosquito bites
0:07:59 > 0:08:00caused her face to swell up.
0:08:00 > 0:08:01You all right?
0:08:01 > 0:08:05Shall we go next door? Go and get a bit more privacy.
0:08:05 > 0:08:06Yeah?
0:08:06 > 0:08:10Have you ever had swelling in the face before?
0:08:10 > 0:08:12- No.- No. OK.
0:08:12 > 0:08:16For safety, she had to end her expedition and go home.
0:08:16 > 0:08:20This was my...literally, my childhood dream to do all this.
0:08:20 > 0:08:22SHE SNIFFS
0:08:22 > 0:08:25And there are plenty of other small creatures waiting to get you..
0:08:25 > 0:08:29- like blood-sucking ticks. - Eurgh! That's mingin'!
0:08:29 > 0:08:31Pick it off me!
0:08:31 > 0:08:35It's really got some quite strong teeth that are locking in there.
0:08:35 > 0:08:36Look at this wee boy.
0:08:36 > 0:08:40Whoa, whoa, whoa, whoa, whoa.
0:08:40 > 0:08:41I'm frightened of them.
0:08:41 > 0:08:44I don't want them to come anywhere near me.
0:08:44 > 0:08:45Scorpion-tastic!
0:08:46 > 0:08:49- There.- Hang on. - Scorpion?- Scorpion.
0:08:49 > 0:08:52This is a speedy one, this one.
0:08:52 > 0:08:55Move this one out of the way carefully, yeah? There we go.
0:08:56 > 0:08:59Yeah. Let's just move the wood and scrape them off,
0:08:59 > 0:09:00just carefully pick them up.
0:09:00 > 0:09:03If we try and catch all of them, we'll be here for a LONG time.
0:09:03 > 0:09:07The jungle team also had to cope with leeches.
0:09:07 > 0:09:09- ALL:- Ergh!
0:09:09 > 0:09:10Oh, that is gross!
0:09:10 > 0:09:11Gross, sorry.
0:09:11 > 0:09:14Eurgh! It was in my belly button!
0:09:14 > 0:09:17Eurgh. I'm really sorry, I panicked.
0:09:17 > 0:09:20And just when you thought it couldn't get any worse,
0:09:20 > 0:09:23imagine finding a deadly snake under your bed.
0:09:26 > 0:09:29It looks black and it looks kind of like the black mamba,
0:09:29 > 0:09:31but I'm not totally sure.
0:09:31 > 0:09:33That's not good, actually.
0:09:33 > 0:09:36- It's very big.- All right, let's get out of here.
0:09:37 > 0:09:39I want that snake out of my house.
0:09:39 > 0:09:42A local tribesman killed the venomous snake,
0:09:42 > 0:09:45and retrieved its last meal -
0:09:45 > 0:09:47a chicken egg!
0:09:47 > 0:09:49Oh, my God!
0:09:49 > 0:09:51That's gross.
0:09:51 > 0:09:53A very uneasy feeling,
0:09:53 > 0:09:57knowing that that's just been under your bed while we've been sleeping.
0:10:01 > 0:10:03Which brings us to sleeping arrangements.
0:10:03 > 0:10:06And Serious Adventurers have slept everywhere,
0:10:06 > 0:10:10from mountaintops to caves to jungles and even glaciers.
0:10:10 > 0:10:13Building a good camp is crucial to surviving.
0:10:13 > 0:10:15But no-one said it was going to be easy.
0:10:15 > 0:10:17With a waterproof sheet for a roof,
0:10:17 > 0:10:21jungle hammocks should keep you safe and dry...
0:10:21 > 0:10:23Whoa!
0:10:23 > 0:10:24..that's if you can stay in them.
0:10:24 > 0:10:26Whoa!
0:10:26 > 0:10:29Can't wait to hear the thuds of people falling out!
0:10:29 > 0:10:31- Are you all right, James?- Help!
0:10:32 > 0:10:34My comfortable hammock.
0:10:34 > 0:10:36THUD!
0:10:36 > 0:10:38Or I might just embarrass myself!
0:10:38 > 0:10:41THEY ALL LAUGH
0:10:41 > 0:10:42Argh!
0:10:42 > 0:10:46In the Arctic, the adventurers got the chance to sleep in an igloo.
0:10:46 > 0:10:49But building one is a skill that takes quite a while to master.
0:10:49 > 0:10:52It's not touching enough.
0:10:52 > 0:10:55It's the corner. That is a corner.
0:10:55 > 0:10:57Calm down.
0:10:57 > 0:10:58Let's just try and reshape it.
0:10:58 > 0:11:00No!
0:11:00 > 0:11:02Oh, it's so annoying.
0:11:02 > 0:11:05Laura's getting the angle wrong,
0:11:05 > 0:11:09and so all the blocks keep falling in. We're actually sleeping in it
0:11:09 > 0:11:11tonight, which is a bit scary,
0:11:11 > 0:11:14because all the sides keep looking like they're going to cave in.
0:11:14 > 0:11:18They told us they'd be putting in a shovel
0:11:18 > 0:11:20so we could dig our way out!
0:11:20 > 0:11:21Yeah-hey!
0:11:26 > 0:11:28In such an extreme environment, you never know
0:11:28 > 0:11:31what surprises the weather might throw at you.
0:11:31 > 0:11:33WIND ROARS
0:11:38 > 0:11:40I got a pole in my head to wake me up,
0:11:40 > 0:11:42and then the whole tent,
0:11:42 > 0:11:44it just came down.
0:11:44 > 0:11:46The winds are blowing really hard!
0:11:48 > 0:11:51The whole tent has just collapsed, and it's so horrible,
0:11:51 > 0:11:54because we're just in the middle of nowhere.
0:11:54 > 0:11:55I think we need to get out.
0:11:55 > 0:11:57Where are we going?
0:11:58 > 0:12:01It's been the most horrible night of my life.
0:12:03 > 0:12:05By morning,
0:12:05 > 0:12:08the storm had devastated the camp.
0:12:08 > 0:12:11I think we must have had 100mph gusts last night,
0:12:11 > 0:12:13and some of these tents -
0:12:13 > 0:12:16they've been to the Antarctic, to the North and South Pole,
0:12:16 > 0:12:18and they've never had this happen to them.
0:12:18 > 0:12:19It was awful.
0:12:19 > 0:12:22Totally, totally awful. I hated it.
0:12:22 > 0:12:24It was like all my fears into one.
0:12:27 > 0:12:30If you're going to survive in any environment,
0:12:30 > 0:12:32you need to know how to build a shelter.
0:12:32 > 0:12:35To make a shelter, you want to find the perfect spot.
0:12:35 > 0:12:38First off, try and get out of the wind and the rain.
0:12:38 > 0:12:41Similarly, rivers, stay off the flood plains,
0:12:41 > 0:12:44but close enough so you can get water to cook with.
0:12:44 > 0:12:47And in the perfect spot, you'd have a beautiful view.
0:12:47 > 0:12:51The first stage to build the shelter is to find a good solid log
0:12:51 > 0:12:55to use as our cross brace for the roof of the shelter.
0:12:55 > 0:12:58We've got perfect little branches
0:12:58 > 0:13:00we can rest our log up against.
0:13:00 > 0:13:02And if you don't have suitable branches, you can use
0:13:02 > 0:13:06V-shaped sticks, which are absolutely mustard
0:13:06 > 0:13:07for jamming logs in place.
0:13:07 > 0:13:11The next thing we're going to need is good solid branches
0:13:11 > 0:13:12to form the roof.
0:13:12 > 0:13:14Use one of these every six to eight inches
0:13:14 > 0:13:17all the way across the roof.
0:13:17 > 0:13:18You may have holes,
0:13:18 > 0:13:21and you may have to lay branches going in the opposite direction.
0:13:21 > 0:13:24Don't forget the sides. The wind and wet can get you through there.
0:13:24 > 0:13:27The last job now is to waterproof the whole thing.
0:13:27 > 0:13:29We're going to use heather. If we were in the jungle,
0:13:29 > 0:13:31we'd be using palm leaves.
0:13:31 > 0:13:35You can never have too much of it. Put it on good and thick.
0:13:35 > 0:13:37- As you look at it, low right.- OK, got it.
0:13:37 > 0:13:40- I think that's looking pretty good, you know.- Yeah.
0:13:40 > 0:13:42I reckon it might be time to try it out.
0:13:42 > 0:13:45Perfect timing! It's just starting to rain.
0:13:45 > 0:13:46I know! Bagsy the back.
0:13:46 > 0:13:47Oh, great(!)
0:13:51 > 0:13:54If there's one environment that gets to most adventurers,
0:13:54 > 0:13:57it's being at sea.
0:13:57 > 0:13:59Life on the ocean wave takes some getting used to,
0:13:59 > 0:14:01from simply making a cup of tea...
0:14:01 > 0:14:05..to the very cramped living conditions, and at some point,
0:14:05 > 0:14:08almost everyone feels a little off-colour.
0:14:13 > 0:14:16In Tanzania, the adventurers had not been at sea for long
0:14:16 > 0:14:18before trouble was brewing.
0:14:21 > 0:14:23I just feel really sick.
0:14:23 > 0:14:26If you are feeling sick, get it over the side
0:14:26 > 0:14:28and try not to get it over other people.
0:14:30 > 0:14:31HE RETCHES
0:14:31 > 0:14:32Oh!
0:14:32 > 0:14:34It's all right, it's normal. Don't worry.
0:14:37 > 0:14:39I can't really stand up for more than five minutes
0:14:39 > 0:14:43without having to sit down again cos I'm feeling so sick.
0:14:45 > 0:14:49What I would give for us to just turn and go to land.
0:14:50 > 0:14:54For the Serious Ocean team, conditions were far, far worse,
0:14:54 > 0:14:57as they were sailing in some of the world's roughest seas.
0:14:58 > 0:14:59Look at the horizon.
0:14:59 > 0:15:01- No!- Yes.- No.
0:15:01 > 0:15:03- It'll help you not feel sick. - It won't!
0:15:03 > 0:15:05You haven't done it yet.
0:15:05 > 0:15:07- Do you feel ill?- Yes.
0:15:07 > 0:15:10Well, go down below and go and lie down.
0:15:10 > 0:15:13And take your puke bowl and put it next to you.
0:15:14 > 0:15:17I was sick, I think, six times.
0:15:17 > 0:15:20David was really, really badly sick.
0:15:20 > 0:15:22HE GROANS
0:15:22 > 0:15:24Oh, it's painful!
0:15:24 > 0:15:27It was the most horrible experience I've ever had in my life.
0:15:27 > 0:15:29Had no energy, couldn't breathe.
0:15:29 > 0:15:31I was saying to myself, "I want to go home."
0:15:33 > 0:15:35You end up retching cos you're just so sick,
0:15:35 > 0:15:37you don't have anything to throw up.
0:15:37 > 0:15:39It really was horrible.
0:15:41 > 0:15:42In such dangerous seas,
0:15:42 > 0:15:45surrounded by ice, the team had to learn what to do
0:15:45 > 0:15:47if they had to abandon ship.
0:15:47 > 0:15:50Let's go! Abandon ship. 30 seconds on deck, go, go!
0:15:50 > 0:15:52Quickly. Grab your boots, on deck.
0:15:52 > 0:15:54Grab anything you've got.
0:15:54 > 0:15:55Move, move, move!
0:15:55 > 0:15:58Just get up those stairs.
0:15:59 > 0:16:01Just as in a real emergency,
0:16:01 > 0:16:04the adventurers transferred to a life raft.
0:16:04 > 0:16:07Oh, my God.
0:16:07 > 0:16:11But being inside such a tiny space wasn't much fun.
0:16:11 > 0:16:13Could you lift your foot up a second?
0:16:13 > 0:16:15OK, don't bother anybody!
0:16:15 > 0:16:17Just move your...
0:16:17 > 0:16:18Charlotte, Charlotte. >
0:16:18 > 0:16:22I know everyone's uncomfortable, but my foot's got
0:16:22 > 0:16:24four people on one shin and it hurts.
0:16:24 > 0:16:26They're already, after five minutes,
0:16:26 > 0:16:28going, "Your leg's on my leg, nerrr."
0:16:28 > 0:16:31Can you imagine spending days and days,
0:16:31 > 0:16:34possibly weeks, on here, in a real survival situation?
0:16:34 > 0:16:38Only good thing about this experience
0:16:38 > 0:16:39is that it will end soon.
0:16:43 > 0:16:46Living so close to people you barely know
0:16:46 > 0:16:49is a bit like being in a pressure cooker -
0:16:49 > 0:16:51sooner or later, something's got to give.
0:16:51 > 0:16:54You didn't give us a chance! You just take on the role without asking.
0:16:54 > 0:16:56- I'll ask if you want to. - You didn't!
0:16:56 > 0:16:59- You didn't ask anyone! - Of course I didn't ask anyone.
0:16:59 > 0:17:01Exactly!
0:17:01 > 0:17:02Setting sail from Chile,
0:17:02 > 0:17:04the Ocean team couldn't even agree
0:17:04 > 0:17:06on who would steer the boat.
0:17:06 > 0:17:08I haven't even had one go...
0:17:08 > 0:17:10ALL TALK AT ONCE
0:17:10 > 0:17:12It was supposed to be me, then Robin, then Sibyl.
0:17:12 > 0:17:14And you're just not....
0:17:14 > 0:17:17We had this really pathetic argument about nothing,
0:17:17 > 0:17:18about who was steering.
0:17:18 > 0:17:21Why can't you have boy, girl, boy, girl, boy, girl?
0:17:21 > 0:17:24"It's my turn to sail. It's my turn to sail.
0:17:24 > 0:17:25"Why can't I sail?"
0:17:25 > 0:17:26Sibyl's waited for ages.
0:17:26 > 0:17:29# Shut up and drive Drive, drive, drive! #
0:17:29 > 0:17:32That's so unfair. Look, Harry's going on.
0:17:32 > 0:17:34I don't really care about going on.
0:17:34 > 0:17:36- Let Harry on!- WATCH THE BOAT!
0:17:36 > 0:17:37Harry, look where the boat's going.
0:17:37 > 0:17:38'It's only day two.'
0:17:38 > 0:17:42You know, we've got another 24 days of this,
0:17:42 > 0:17:45and they're bickering like anything. I mean, this boat is a nightmare.
0:17:45 > 0:17:47I'm not talking to you. I'm asking nicely.
0:17:47 > 0:17:50You just gave me a big lecture about not walking off
0:17:50 > 0:17:52on the things I said I'd do!
0:17:52 > 0:17:53Katie, Katie...
0:17:53 > 0:17:56They're telling me to stop shouting but I wasn't. THIS IS SHOUTING!
0:17:56 > 0:18:00While boats are particularly bad for what's commonly called cabin fever,
0:18:00 > 0:18:05the stress of living rough can boil over in any extreme environment.
0:18:05 > 0:18:06Drives me insane!
0:18:06 > 0:18:09It's the first week. I don't think it's a very good start.
0:18:09 > 0:18:14There's tension...you can cut it with a knife. Watch.
0:18:14 > 0:18:16MIMICS CUTTING NOISE
0:18:16 > 0:18:18It's only my hand!
0:18:19 > 0:18:22I just don't like her. If she comes near me today, I'll punch her.
0:18:22 > 0:18:25Day 7 in the Serious Desert Diary Room.
0:18:25 > 0:18:27Perry decides to slag everyone off.
0:18:27 > 0:18:28Especially Amy.
0:18:28 > 0:18:31Amy came back from rhino tracking today
0:18:31 > 0:18:34started having a go at us all for not doing stuff and faffing around.
0:18:34 > 0:18:37Well, how would she know we're faffing around
0:18:37 > 0:18:39if she's not even there?
0:18:39 > 0:18:42Doing funny jokes and doing impressions
0:18:42 > 0:18:44and stuff doesn't build a wall.
0:18:44 > 0:18:46"I'm not doing it. I'm getting out.
0:18:46 > 0:18:48"I'm not doing it."
0:18:48 > 0:18:49If he says one more thing about me,
0:18:49 > 0:18:52I'm going to literally go over there and smash his face in.
0:18:52 > 0:18:54He's talking about me now.
0:18:54 > 0:18:56"I'm going as fast as I can!"
0:18:58 > 0:18:59SHE SIGHS
0:18:59 > 0:19:01That's who I'm talking about.
0:19:01 > 0:19:02She's got my head torch. >
0:19:02 > 0:19:05No, Nicky, it does not have your head torch!
0:19:06 > 0:19:08Arguments aside,
0:19:08 > 0:19:11expeditions are packed with amazing experiences.
0:19:11 > 0:19:13But wherever your adventures take you,
0:19:13 > 0:19:15be it mountain or river, desert or jungle,
0:19:15 > 0:19:18there's one skill everyone needs to master.
0:19:22 > 0:19:25One of the most important things every adventurer needs to know
0:19:25 > 0:19:27is how to build a fire.
0:19:27 > 0:19:30It's often the only way to keep warm or get a hot meal.
0:19:30 > 0:19:32But as the Serious Adventurers have found out,
0:19:32 > 0:19:35it takes a lot of practice to get this right.
0:19:35 > 0:19:38This really isn't going well for a first night out.
0:19:38 > 0:19:40We can't get the fire going.
0:19:40 > 0:19:42Everybody's tried and failed.
0:19:42 > 0:19:44I'm beginning to get a bit worried.
0:19:44 > 0:19:47I'm not sure we're actually ever going to get any food.
0:19:47 > 0:19:48It must have taken about half an hour
0:19:48 > 0:19:50to 40 minutes to light the fire,
0:19:50 > 0:19:52which...
0:19:52 > 0:19:54is quite laughable, really.
0:19:58 > 0:20:01In Tanzania, the local Mnyati tribe made it look easy,
0:20:01 > 0:20:05but the secrets have been passed down over generations.
0:20:05 > 0:20:06Wow!
0:20:06 > 0:20:07THEY APPLAUD
0:20:08 > 0:20:12It's really difficult to get even an ember going.
0:20:12 > 0:20:14When you spin the stick, it falls out of the hole
0:20:14 > 0:20:17and it's just really annoying.
0:20:17 > 0:20:18Come on!
0:20:18 > 0:20:22That's it. Go on. Get your face right down in there and blow it.
0:20:25 > 0:20:27Woo-hoo!
0:20:27 > 0:20:28We win!
0:20:29 > 0:20:32The key to lighting a fire is to be prepared.
0:20:32 > 0:20:34First, you need matches or a lighter,
0:20:34 > 0:20:38and just make sure that they're in a good, waterproof bag.
0:20:38 > 0:20:40Start off with whatever's around you that's dry.
0:20:40 > 0:20:42Moss is great,
0:20:42 > 0:20:44or maybe the inside of tree bark, but also pine needles
0:20:44 > 0:20:47are fantastic just to get the fire going initially.
0:20:47 > 0:20:51You want to get nice, dry wood that just snaps at 90 degrees.
0:20:51 > 0:20:53OK, let's go for it.
0:20:53 > 0:20:55No-one said it was going to be easy.
0:20:55 > 0:20:59Lighting fires is as much patience as anything else.
0:20:59 > 0:21:01As you've got a bed to the fire,
0:21:01 > 0:21:04you just want to start adding little twigs very slowly.
0:21:04 > 0:21:06Don't try and put them all on at once.
0:21:06 > 0:21:08You want to try and make a wigwam
0:21:08 > 0:21:11so air can get right into the bottom of the fire.
0:21:11 > 0:21:14It doesn't matter whether the fire is only this size
0:21:14 > 0:21:17or massive, it's still hot.
0:21:17 > 0:21:19So always take care.
0:21:19 > 0:21:21Just keep blowing from quite low down,
0:21:21 > 0:21:24and that just keeps the air moving,
0:21:24 > 0:21:26keeping it nice and hot in the core.
0:21:26 > 0:21:29Try not to be where I am, on the downwind, smoky side,
0:21:29 > 0:21:32because when Polly blows, I get a face full.
0:21:32 > 0:21:34Once you've got the fire established,
0:21:34 > 0:21:36you want to start filling in bigger logs.
0:21:36 > 0:21:39Place the ends into the bottom of the embers.
0:21:39 > 0:21:43The ends of the fat logs will start turning into big, red embers,
0:21:43 > 0:21:47and that's really going to be the heart of the fire to then cook on.
0:21:47 > 0:21:50As these bits of wood start burning down,
0:21:50 > 0:21:53you can just gradually feed them into the middle.
0:21:53 > 0:21:56You don't have to mess around trying to chop wood and that kind of stuff.
0:21:56 > 0:21:58That's good.
0:21:58 > 0:22:01So fire is nice and hot, five minutes' time,
0:22:01 > 0:22:02put the pot on, ready to eat.
0:22:04 > 0:22:06Once you've got the fire going,
0:22:06 > 0:22:08you can get cooking.
0:22:08 > 0:22:11But the extreme menu might not be to everyone's taste.
0:22:15 > 0:22:18I'm not eating that. I refuse to eat that.
0:22:18 > 0:22:20- Does everyone want to grab a leg? - No way!
0:22:20 > 0:22:23In the Amazon, you've got to try a bit of spider leg.
0:22:23 > 0:22:24Just look at it, though!
0:22:24 > 0:22:27- Eurgh, it's all furry still! - Hairy, though.
0:22:27 > 0:22:28I'm not eating a furry leg.
0:22:28 > 0:22:30You've got to go for the furry leg.
0:22:30 > 0:22:33- Oh, it's actually quite nice! - It is, isn't it?
0:22:33 > 0:22:35- Who's going to go with the... - Me!- ..cucaracha?
0:22:35 > 0:22:36Go on, Jamie!
0:22:36 > 0:22:38Chew, Jamie, chew!
0:22:38 > 0:22:40Eurgh!
0:22:40 > 0:22:42Eurgh!
0:22:42 > 0:22:46This is an absolute delicacy out here. It's called a mopane worm.
0:22:46 > 0:22:47Look at it.
0:22:49 > 0:22:50I can't do that, please.
0:22:50 > 0:22:51Is it alive?
0:22:51 > 0:22:53- I can't do it.- Please.
0:22:53 > 0:22:55You've only got one chance at it!
0:22:55 > 0:22:56Go on!
0:22:56 > 0:22:58Yay!
0:23:02 > 0:23:03Is it eating you?
0:23:03 > 0:23:04- What does it taste like?- Mmmm!
0:23:04 > 0:23:05THEY LAUGH
0:23:05 > 0:23:08- Megan, you go for that one. - Go for it.
0:23:08 > 0:23:10Go for it.
0:23:10 > 0:23:12Chew. Chomp, chomp, chomp.
0:23:12 > 0:23:15- It tastes of mud!- Awww!
0:23:16 > 0:23:18Lovely(!)
0:23:18 > 0:23:20You're vegetarian!
0:23:22 > 0:23:24It has to be done.
0:23:24 > 0:23:25THEY LAUGH
0:23:26 > 0:23:29When am I going to get the chance to eat a worm again?
0:23:29 > 0:23:30And it's not always
0:23:30 > 0:23:32just bugs and creepy crawlies.
0:23:32 > 0:23:36After a cull of beavers by local scientists,
0:23:36 > 0:23:39the Serious Ocean adventurers found the cute creature
0:23:39 > 0:23:41on their dinner menu.
0:23:41 > 0:23:43- The smell's putting me off. - It's cooked to perfection.
0:23:43 > 0:23:47I agree the smell is pretty revolting, but I think
0:23:47 > 0:23:50it's worth trying, because the meat is very tasty.
0:23:50 > 0:23:52- OK.- And I think you'll be surprised.
0:23:54 > 0:23:57- I can't even bring myself to chew that.- It's amazing.
0:23:59 > 0:24:03I expected it to be really horrible, but it's really, really nice.
0:24:03 > 0:24:06It's like steak on a stick.
0:24:06 > 0:24:08THEY LAUGH
0:24:08 > 0:24:10Which brings us to our last,
0:24:10 > 0:24:13and perhaps most important survival ingredient.
0:24:17 > 0:24:22Even more essential than food in a survival situation is water.
0:24:22 > 0:24:25Trekking for weeks at a time makes it virtually impossible
0:24:25 > 0:24:28to carry enough water for everyone.
0:24:28 > 0:24:32It means you may have to utilise streams and purify water as you go.
0:24:32 > 0:24:34Or look in more unusual places.
0:24:34 > 0:24:37Drinkable water might be contained in a vine..
0:24:37 > 0:24:39- There it is.- There we go.
0:24:39 > 0:24:42It's a really funny taste, but it's nice. Good.
0:24:42 > 0:24:44Is it nice?
0:24:44 > 0:24:46That could take a long time to quench my thirst.
0:24:46 > 0:24:48..or even in a fish's eyeball.
0:24:48 > 0:24:50This is the only part of a fish
0:24:50 > 0:24:54that has fresh water in it, so in a survival situation,
0:24:54 > 0:24:56you'd go to eat the eyeball.
0:24:56 > 0:25:00You can chew it, yeah. Chew it and then down the hatch.
0:25:02 > 0:25:04TALKS WITH MOUTH FULL
0:25:04 > 0:25:05It tastes, like, bony.
0:25:07 > 0:25:08This is disgusting.
0:25:08 > 0:25:11It feels like I'm eating...
0:25:11 > 0:25:14but it doesn't actually taste that bad, though, surprisingly.
0:25:15 > 0:25:17The desert is notorious for its lack of water,
0:25:17 > 0:25:21so in an emergency, desperate adventurers
0:25:21 > 0:25:24have been known to try almost anything.
0:25:24 > 0:25:26Where have we got water that's going to waste?
0:25:26 > 0:25:29- Trees?- Washing?
0:25:29 > 0:25:31Trees, yeah. Washing.
0:25:31 > 0:25:33- Bath.- When we...urinate?- Urine.
0:25:33 > 0:25:34Oh. Ohhh!
0:25:36 > 0:25:38- Now that is fun.- That's rank!
0:25:38 > 0:25:39So, we're just going to have a go
0:25:39 > 0:25:43- at seeing how we can drink our own urine.- No!- Oh, no.
0:25:43 > 0:25:46- I'll be sick! - That's just nasty.
0:25:46 > 0:25:48To turn their wee into drinkable water,
0:25:48 > 0:25:51they tried to make a solar still.
0:25:51 > 0:25:55You don't want pee in there. This is your clean drinking water bottle.
