0:00:33 > 0:00:34CHEERING AND APPLAUSE
0:00:34 > 0:00:38Lab rat, here's the special stick of glowing rock I promised you.
0:00:38 > 0:00:40That's for being a good lab rat. Well done.
0:00:40 > 0:00:43On an unrelated note, here's a stick of uranium.
0:00:43 > 0:00:46Put that in the generator. It's important you don't mix those up,
0:00:46 > 0:00:49because obviously you can't power the lab with rock,
0:00:49 > 0:00:53and uranium is really bad for your teeth, OK? Go on, get on with it.
0:00:53 > 0:00:56Hello, I'm Richard Hammond. This is my Blast Lab.
0:00:56 > 0:00:57CHEERING AND APPLAUSE
0:01:00 > 0:01:03Actually, I think those two were the wrong way round.
0:01:03 > 0:01:06I might have given him the uranium instead of the rock.
0:01:06 > 0:01:09Don't chew either of them, OK? They'll be deadly. Right.
0:01:09 > 0:01:13- Two teams are about to embark on... - EXPLOSION
0:01:13 > 0:01:17Yeah. Yeah, he may have chewed the wrong one.
0:01:17 > 0:01:21Coming up today we have Fact Nav 2.0 with my good friend Oliver.
0:01:26 > 0:01:29In Mini Science we shall be testing the immense strength
0:01:29 > 0:01:31of the humble egg.
0:01:34 > 0:01:38And for the first time ever, my lab rats will be in charge
0:01:38 > 0:01:40of an egg-straordinary experiment.
0:01:43 > 0:01:47And talking of mess, we return to the septic tank
0:01:47 > 0:01:48as we play Gungey Bungee.
0:01:54 > 0:01:57To ensure everything in my lab is kept top secret -
0:01:57 > 0:02:01my experiments, my diary, my dolly collection -
0:02:01 > 0:02:05I employ the best security guard custard creams can buy.
0:02:05 > 0:02:08- It is, of course, my Ninja Nan! - CHEERING AND APPLAUSE
0:02:15 > 0:02:21There she is, in the Ninja Nannex, probably doing something exciting
0:02:21 > 0:02:24like practising the nunchucks or breaking wood with her hands,
0:02:24 > 0:02:27or doing a jigsaw as it turns out.
0:02:27 > 0:02:30Let's have a look at who's trying to get into my lab today.
0:02:35 > 0:02:39OK, you guys claim to be the Red Team. I'm sure
0:02:39 > 0:02:42you won't mind if we carry out some security checks.
0:02:42 > 0:02:45So for security reasons, your names are, please? What are they?
0:02:45 > 0:02:48- Hugo.- Tom.- Alfie.
0:02:48 > 0:02:51Hugo, Tom and Alfie. That's what I've got down here.
0:02:51 > 0:02:55It says under hidden talent, "Tom." What are you going to do for us?
0:02:55 > 0:02:57I'm going to do karate.
0:02:57 > 0:03:01Really? Ninja Nan's in there with you. Just be careful, OK?
0:03:01 > 0:03:02Very quickly.
0:03:04 > 0:03:08Well done. I reckon he might have taken her down. Come on in.
0:03:12 > 0:03:14If Ninja Nan had seen those moves, Tom,
0:03:14 > 0:03:16there would have been a lot of trouble.
0:03:16 > 0:03:19You're pretty much through. One final thing remains
0:03:19 > 0:03:21to make absolutely sure you are the real Red Team.
0:03:21 > 0:03:24We agreed a password with the real Red Team.
0:03:24 > 0:03:28- If you can tell me what that is. - RED TEAM: Technology.
0:03:28 > 0:03:31That's kind of relevant to what we do here. Any reason for that?
0:03:31 > 0:03:34We all love technology and we all love computer games.
0:03:34 > 0:03:37Really? Well, good luck in the lab today.
0:03:37 > 0:03:40Go and get settled in for the first round. Away you go, Red Team.
0:03:40 > 0:03:42CHEERING AND APPLAUSE
0:03:42 > 0:03:46That is our official Red Team. That's confirmed it. Let's meet
0:03:46 > 0:03:49the other bunch of people trying to get into my lab today.
0:03:53 > 0:03:56Hello! Right, you lot claim to be the Yellow Team.
0:03:56 > 0:03:59For security purposes, can I confirm your names, please?
0:03:59 > 0:04:02- Janice.- Ashley.- Jamila.
0:04:02 > 0:04:05Janice, Ashley, Jamila. That's what I've got written down. OK.
0:04:05 > 0:04:07Jamila, your name's under "talent".
0:04:07 > 0:04:09What can you do to prove you are who you are?
0:04:09 > 0:04:10Play the recorder.
0:04:10 > 0:04:13Go on then. If you can play the recorder, you'll be into the lab.
0:04:13 > 0:04:16That's the right end. That's good.
0:04:16 > 0:04:18PLAYS "THREE BLIND MICE"
0:04:18 > 0:04:21OK. Well, I don't feel a single coming on, but...
0:04:23 > 0:04:27..that's a recorder. The noise is coming out of it. Come on in.
0:04:27 > 0:04:28CHEERING AND APPLAUSE
0:04:30 > 0:04:34Welcome to the Blast Lab, you three. OK, fair enough you're in this far,
0:04:34 > 0:04:38but we have to continue with our security checks.
0:04:38 > 0:04:39We can't be too careful.
0:04:39 > 0:04:42A password has been agreed with the real Yellow Team.
0:04:42 > 0:04:45If you are the real Yellow Team, you'll know what that is.
0:04:45 > 0:04:47- What is it?- YELLOW TEAM: Bore da!
0:04:47 > 0:04:50That's what it says here. What does that mean?
0:04:50 > 0:04:52It's good morning in Welsh.
0:04:52 > 0:04:54That confirms it. You are the Yellow Team.
0:04:54 > 0:04:58Go and get settled in, ready for round one. You are our Yellow Team.
0:04:58 > 0:05:02For the next round I shall need the help of a car who struggled to get
0:05:02 > 0:05:05points for speeding, but could easily get points on Mastermind.
0:05:05 > 0:05:06It is, of course, Oliver.
0:05:24 > 0:05:26HORN BEEPS
0:05:28 > 0:05:32Come on, my friend. There you go. Let's plug him in. That's Oliver.
0:05:32 > 0:05:36Until recently the most state of the art technology that
0:05:36 > 0:05:39Oliver had was... well, his wheels, really.
0:05:39 > 0:05:42So to bring him into the 21st century, I've installed
0:05:42 > 0:05:45a Fact Nav 2.0 system, and it all went swimmingly well,
0:05:45 > 0:05:48by which I mean, I spilled a lot of water on it
0:05:48 > 0:05:50and now it doesn't quite work.
0:05:50 > 0:05:54It's your job, teams, to work out what's true and what's false.
0:05:54 > 0:05:56If a fact is true, Oliver will make this noise -
0:05:56 > 0:05:59HORN BEEPS
0:05:59 > 0:06:03And if a fact is false, Oliver will let us know by making this noise -
0:06:03 > 0:06:05FOGHORN BLARES
0:06:05 > 0:06:09Teams, you will both notice both teams have three lights.
0:06:09 > 0:06:13At the moment, they're all red. Every time you get a question right,
0:06:13 > 0:06:15it will light one of your own lamps green.
0:06:15 > 0:06:20Turns it green. Really important, because when you get three green,
0:06:20 > 0:06:24that team wins. However, if, when you're answering a question,
0:06:24 > 0:06:26you get it wrong, it doesn't turn your light green,
0:06:26 > 0:06:29it turns the other team's light green.
0:06:29 > 0:06:32Very, very important that you think carefully before you answer, OK?
0:06:32 > 0:06:35We're going to start with a Nearest To question.
0:06:35 > 0:06:41How far does the minute hand of Big Ben travel each year?
0:06:41 > 0:06:43Have a think, have a chat. You never know.
0:06:43 > 0:06:47How far does the minute hand of Big Ben travel each year, in miles?
0:06:47 > 0:06:50It's a big clock.
0:06:50 > 0:06:54Oh! Going to have to rush you. Time's going to be up.
0:06:54 > 0:06:57Get an answer written down. If you've got an answer written down...
0:06:57 > 0:06:59Six miles from the Reds.
0:06:59 > 0:07:04From the Yellows... Five miles. You say five miles, OK.
0:07:04 > 0:07:09Six from the Reds, five from the Yellows. The real answer is...
0:07:10 > 0:07:16118 miles, which means the Reds win that one. Let's light a light.
0:07:16 > 0:07:17CHEERING AND APPLAUSE
0:07:19 > 0:07:23It's actually 4.2 metres long, the minute hand, and it goes round
0:07:23 > 0:07:27and round the clock face doing 118 miles a year.
0:07:27 > 0:07:30Right. That means, Reds, you seize control of the game.
0:07:30 > 0:07:34You get the first true or false question.
0:07:34 > 0:07:38An average human body contains enough iron
0:07:38 > 0:07:41to make a five centimetre long nail.
0:07:41 > 0:07:44Have a think, have a chat amongst yourselves.
0:07:44 > 0:07:46An average human body contains enough iron to make
0:07:46 > 0:07:49a five centimetre long nail. True or false? what do you think?
0:07:49 > 0:07:51- False.- You think it's false.
0:07:51 > 0:07:54Oliver, is it true or is it false?
0:07:54 > 0:07:56- HORNS BEEP - It's true! I'm sorry.
0:07:56 > 0:08:00I'm sorry, Reds. It's true. That means we light a lamp green
0:08:00 > 0:08:04for the Yellows. And it's now your question. That's how the game works.
0:08:04 > 0:08:07You get it wrong, you give them the point. Right, Yellows,
0:08:07 > 0:08:10this is your first chance. Here is your science fact.
0:08:10 > 0:08:15Oxygen only exists as a gas.
0:08:15 > 0:08:19Oxygen only exists as a gas. Is that true or false?
0:08:19 > 0:08:21Don't answer straight away. Have a chat. You never know.
0:08:21 > 0:08:24One of you might know something that just helps with it.
0:08:24 > 0:08:28Audience, let's see what you think. Vote with your feet. Away you go.
0:08:28 > 0:08:30KLAXON
0:08:30 > 0:08:33This is what I like to see. All of the audience thinks yes,
0:08:33 > 0:08:37apart from one who thinks no. You think false.
0:08:37 > 0:08:42- It can be in water.- Even with all of that lot thinking otherwise,
0:08:42 > 0:08:45that's somebody who knows her own mind.
0:08:45 > 0:08:47Audience, back to your places.
0:08:48 > 0:08:52And to remind you - oxygen only exists as a gas. True or false?
0:08:52 > 0:08:56- What do you think?- True. - You think it's true.
0:08:56 > 0:08:58Oliver, is it true or is it false?
0:08:58 > 0:09:00- FOGHORN BLARES - It's false.
0:09:00 > 0:09:05And that means another lamp is lit for the Red Team. They're on two.
0:09:05 > 0:09:08Puts them ahead. I'm sorry, that's how it works.
0:09:08 > 0:09:14Right. Let's move on to the Red Team. Here is your fact.
0:09:14 > 0:09:18A cat has more bones than a human.
0:09:18 > 0:09:21Does it or doesn't it? Have a think, have a chat. You never know,
0:09:21 > 0:09:23one of you might just have picked something up.
0:09:23 > 0:09:27A cat has more bones than a human. To win the game,
0:09:27 > 0:09:29or give them a point, is that true or false?
0:09:29 > 0:09:34- True.- You think it's true. Have you counted the bones in a cat ever?
0:09:34 > 0:09:37- Yeah.- OK, you have. Marvellous. Let's see what Oliver thinks.
0:09:37 > 0:09:39- Oliver, is that true or false? - HORNS BEEP
0:09:39 > 0:09:42It's true! That means three lights are lit for the Reds.
0:09:42 > 0:09:46I'm afraid they win the first round, Yellows. Well done.
0:09:48 > 0:09:52- How did you know that?- Guess.
0:09:52 > 0:09:55It was a guess. In fact, a cat's skeleton is made up of around
0:09:55 > 0:09:59230 bones, whereas, us humans have got about 206,
0:09:59 > 0:10:03which means the Reds take the point. They're in the lead. Well done.
0:10:19 > 0:10:23A while ago, I designed and built a time machine
0:10:23 > 0:10:25to bring my old science teacher back from school,
0:10:25 > 0:10:28here through to the lab. And it worked perfectly.
0:10:28 > 0:10:31Apart from one small technical hitch,
0:10:31 > 0:10:34because my teacher made it here, only now she looks like
0:10:34 > 0:10:37a ten-year-old girl. She is, of course, Mini Miss.
0:10:43 > 0:10:46Are you calling me a tiny technical hitch, Richard?
0:10:46 > 0:10:49No, Miss. Wouldn't dream of it, Miss. Absolutely not.
0:10:49 > 0:10:50Mini Miss might look like a ten-year-old,
0:10:50 > 0:10:54but she's actually a fully qualified teacher with many, many,
0:10:54 > 0:10:56many years' experience,
0:10:56 > 0:10:59mostly of telling me to stop talking and sit at the back
0:10:59 > 0:11:00when I was at school,
0:11:00 > 0:11:03- because I used to... - Stop talking, Richard.
0:11:03 > 0:11:05- Sorry, Miss.- Today, we're playing...
0:11:07 > 0:11:11Oh, are you sure you want to call it that, Miss?
0:11:11 > 0:11:15Only, sometimes, you know, doctors and medical people,
0:11:15 > 0:11:19when they say "stool," they don't mean something you sit on,
0:11:19 > 0:11:22they mean, you know, it's kind of something rather different.
0:11:22 > 0:11:25We're not going to be using lots of...it's...
0:11:25 > 0:11:27Ignore him.
0:11:27 > 0:11:30- Don't be ridiculous, Richard. - Just saying.
0:11:30 > 0:11:34This game involves our teams placing a variety of objects
0:11:34 > 0:11:36onto this sheet,
0:11:36 > 0:11:38which is balanced by eggs.
0:11:38 > 0:11:42OK, so they take it in turns to select an object from over here,
0:11:42 > 0:11:44and place it onto this sheet,
0:11:44 > 0:11:48and, let me guess, whichever team causes the eggs to crack loses,
0:11:48 > 0:11:51and the other team gets an omelette! Am I right?
0:11:51 > 0:11:54- Except for the omelette part, yes. - OK, fair enough.
0:11:54 > 0:11:56Before you get started on this, teams,
0:11:56 > 0:11:59Mini Miss is going to talk you through your options, OK? Do listen.
0:11:59 > 0:12:02You might be thinking this will be quick,
0:12:02 > 0:12:04but eggs are actually surprisingly strong,
0:12:04 > 0:12:06especially when you push them at their ends,
0:12:06 > 0:12:10because the shape spreads the force all around the egg's surface,
0:12:10 > 0:12:13meaning it doesn't crack...hopefully.
0:12:13 > 0:12:15Also, we've got four eggs here,
0:12:15 > 0:12:18so, if you think, each of those will be sharing a little bit
0:12:18 > 0:12:19of the weight of the objects,
0:12:19 > 0:12:23just a quarter of it is all they'll have to hold up on their own.
0:12:23 > 0:12:25Let's see how much weight these eggs can take.
0:12:25 > 0:12:28Right, teams, I think you've had enough thinking time now.
0:12:28 > 0:12:30The Red Team won Fact Nav,
0:12:30 > 0:12:34so you choose whether you want to go first or second with this.
0:12:34 > 0:12:37What do you want to do, first or second?
0:12:37 > 0:12:38- First.- You want to go first.
0:12:38 > 0:12:40OK, let's get on with it.
0:12:42 > 0:12:46They're making their decision.
0:12:46 > 0:12:47- Have you decided?- Yes.
0:12:47 > 0:12:49It's the cake, they've gone for the cake!
0:12:49 > 0:12:50Oooh!
0:12:50 > 0:12:55OK, it's on, it's on. Well done, Red Team, for the first round.
0:12:55 > 0:12:58'That's almost 1.9 kilograms of cake.'
0:12:58 > 0:13:01OK. OK, right. Yellows.
0:13:04 > 0:13:06Come forwards, and choose your object.
0:13:06 > 0:13:09Always best to concentrate.
0:13:09 > 0:13:11Janice is going for the oven glove.
0:13:11 > 0:13:15I reckon this is a safe bet.
0:13:15 > 0:13:1850 grams of oven glove has joined it, well done! Nice one, Yellows.
0:13:18 > 0:13:20OK. Well done, Yellows.
0:13:22 > 0:13:26Reds, the pressure's on, you've got to return serve.
0:13:26 > 0:13:28- Chaps, have we decided?- Yes.
0:13:28 > 0:13:32OK, it's the egg timer from the Red Team. It's a little one.
0:13:32 > 0:13:34Oh, yeah, you've got away with that.
0:13:34 > 0:13:37'That brings the total to just over two kilograms.'
0:13:37 > 0:13:41Yellows, lining up their shot, and they've gone for the egg whisk.
0:13:41 > 0:13:44Well done, Ashley, well done. There you go, we're OK!
0:13:44 > 0:13:46We're in the clear! Well done, Yellows.
0:13:48 > 0:13:50Winding up to be a long game, this one.
0:13:53 > 0:13:57Reds, come on. It's the discussion.
0:13:57 > 0:13:59Have you made your decision? What are you going for?
0:13:59 > 0:14:01- The rolling pin.- The rolling pin.
0:14:01 > 0:14:03'Ooh the rolling pin. 300 grams.'
0:14:06 > 0:14:09All four eggs spreading that weight between them,
0:14:09 > 0:14:11we must be up to the best part of three kilograms,
0:14:11 > 0:14:15so each one supporting a quarter of that.
0:14:15 > 0:14:18Yellows, please make a choice. Oh, oh, oh!
0:14:18 > 0:14:21The game's really hotting up now.
0:14:21 > 0:14:24Ooh, they've gone for the biscuit barrel.
0:14:24 > 0:14:27Jamila going for the place, she's going for the place.
0:14:27 > 0:14:30It's up, it's supported. Well done!
0:14:32 > 0:14:35Step forward, Reds. It's the pressure, he's cracking under it.
0:14:35 > 0:14:38'What's he going to go for? Ooh, it's the teapot,
0:14:38 > 0:14:39'800 grams' worth.'
0:14:39 > 0:14:41Oh!
0:14:41 > 0:14:44Ooh! Nice move, nice move.
0:14:47 > 0:14:50The teapot weighs exactly the same as the biscuit barrel.
0:14:50 > 0:14:54It's a classic return move in Eggy Stool.
0:14:54 > 0:14:57Right, Yellows, come forwards, make your choice.
0:14:57 > 0:15:01This game is going all the way. The atmosphere in the lab tense now.
0:15:06 > 0:15:08Ooh, now, that's an interesting object.
0:15:08 > 0:15:12This is quite a brave move at this stage in the game.
0:15:14 > 0:15:19'1.7 kilograms. The cake is the only heavier item on our egg table.'
0:15:19 > 0:15:22A lot of concentration right now.
0:15:22 > 0:15:26OK, can you find a space, even, to accommodate this?
0:15:26 > 0:15:281.7 kilograms, those scales weigh.
0:15:28 > 0:15:32About to add it to a Ninja Nan sponge cake,
0:15:32 > 0:15:34a rolling pin, oven glove, egg timer,
0:15:34 > 0:15:36egg whisk, biscuit barrel, and teapot.
0:15:38 > 0:15:42- Er, it's got a tiny little dent. - Ooh. Ooh, it's getting close!
0:15:42 > 0:15:43Oh!
0:15:44 > 0:15:47Yellows, I'm so sorry.
0:15:47 > 0:15:52Two eggs cracking, there, under the weight of 5.8kg.
0:15:52 > 0:15:54So that's another point to the Reds.
0:15:54 > 0:15:562-0 to the Reds. Well done.
0:15:56 > 0:15:58CHEERING AND APPLAUSE
0:16:00 > 0:16:02So eggs are pretty strong,
0:16:02 > 0:16:04but, I mean, I could lift that lot.
0:16:04 > 0:16:06I wonder if eggs can support something
0:16:06 > 0:16:09really super mega Ninja Nan's handbag heavy?
0:16:10 > 0:16:13Strength! It comes in many forms.
0:16:15 > 0:16:19Iron, steel, titanium - all names that strike fear
0:16:19 > 0:16:22and cause sleepless nights amongst the likes of lettuce,
0:16:22 > 0:16:24candyfloss and wet paper bags.
0:16:24 > 0:16:30But there is another unsung hero, who's been biding its time
0:16:30 > 0:16:32until today, when it's finally decided
0:16:32 > 0:16:34to step forth into the limelight.
0:16:34 > 0:16:36To whom am I referring?
0:16:36 > 0:16:41It's the friend of bakers, fry-ups and Easter bunnies across the world.
0:16:41 > 0:16:44It is, of course, the egg.
0:16:44 > 0:16:46But the egg isn't unbreakable.
0:16:47 > 0:16:51For it to be unbreakable, you've got to unlock the science.
0:16:51 > 0:16:53I think we need a graphic.
0:16:53 > 0:16:56Apart from being a versatile, protein-packed snack,
0:16:56 > 0:16:59an egg's shape is perfect for spreading weight.
0:16:59 > 0:17:02Eggs are strong when pushed from the top to the bottom
0:17:02 > 0:17:07because the force of the push is spread around the egg surface.
0:17:07 > 0:17:10This means eggs can take more weight than you might think.
0:17:10 > 0:17:15But if you push sideways on the egg, the force isn't spread out
0:17:15 > 0:17:16so causes an eggy explosion.
0:17:16 > 0:17:22We're going to see if science can redefine the egg's fragile image.
0:17:22 > 0:17:26First we need to find out how strong eggs really are. Will one egg
0:17:26 > 0:17:29be strong enough to hold one lab rat's body weight?
0:17:29 > 0:17:32No. OK, what about two eggs?
0:17:34 > 0:17:38No. OK. Let's go for four eggs.
0:17:40 > 0:17:45This really is riveting scientific endeavour at its very best.
0:17:46 > 0:17:49Surprise - eight eggs. Who's have thought it?!
0:17:51 > 0:17:54Ooh, it looks like it's holding.
0:17:54 > 0:17:57At last, success!
0:17:57 > 0:18:01We've learned that eight eggs can hold the weight of one lab rat.
0:18:01 > 0:18:04A lab rat weighs... How much?
0:18:04 > 0:18:06OK.
0:18:06 > 0:18:11If you say so. Eight eggs to hold up 79 kilos of lab rat.
0:18:11 > 0:18:16What if we tried this with something heavier, much heavier,
0:18:16 > 0:18:19say...that. A helicopter.
0:18:24 > 0:18:27That weighs about 1,000 kilos,
0:18:27 > 0:18:30so how many eggs would it take to hold up 1,000 kilos?
0:18:30 > 0:18:35Equals how many eggs?
0:18:35 > 0:18:38The number of eggs.
0:18:42 > 0:18:44I'm going to leave you to work this out.
0:18:44 > 0:18:46I'll be back later.
0:18:46 > 0:18:52So I'm going to leave the lab rats to figure this out.
0:18:56 > 0:18:58Now, today is a world's first.
0:18:58 > 0:19:03And I'm not talking about landing a helicopter on eggs.
0:19:03 > 0:19:07It's that I've entrusted my lab rats to set up this experiment
0:19:07 > 0:19:09without any supervision.
0:19:09 > 0:19:12Am I confident of success? Well, the science adds up.
0:19:12 > 0:19:15There's always that human error factor,
0:19:15 > 0:19:17or in this case, the lab rat factor.
0:19:19 > 0:19:21Brilliant(!)
0:19:23 > 0:19:25After only three months of calculations,
0:19:25 > 0:19:28and the counting of hundreds of lab rats' fingers,
0:19:28 > 0:19:30they've finally worked out
0:19:30 > 0:19:33756 eggs should be enough to support the weight of the helicopter.
0:19:33 > 0:19:35SHOULD be.
0:19:36 > 0:19:40Well, we'll soon find out, that's for sure.
0:19:40 > 0:19:44On our final approach and there is the heli-egg pad.
0:19:44 > 0:19:48I did leave the lab rats to calculate the number of eggs.
0:19:49 > 0:19:52That means I'm trusting them...
0:19:52 > 0:19:54with a helicopter.
0:19:54 > 0:19:58Have the lab rats got something right for a change?
0:19:58 > 0:20:03Will 756 eggs support the weight of a helicopter?
0:20:03 > 0:20:07I hope so, otherwise this could get very messy.
0:20:07 > 0:20:09OK, hold the experiment right there
0:20:09 > 0:20:12because I think there could be another point here.
0:20:12 > 0:20:14The Reds are ahead by two at the moment.
0:20:14 > 0:20:18Let's go for the point, OK? I'll give the point
0:20:18 > 0:20:20to the team who gives the most accurate answer.
0:20:20 > 0:20:24How many eggs in the heli-egg pad do you think will break?
0:20:24 > 0:20:26From nought,
0:20:26 > 0:20:28none of them, to 756.
0:20:28 > 0:20:29That's all of them.
0:20:29 > 0:20:34Have a talk between the three of you and come up with a number.
0:20:34 > 0:20:37None of them, some of them, all of them.
0:20:37 > 0:20:40I will give the point to the team that gets closest.
0:20:40 > 0:20:42Yellows, what do you think?
0:20:42 > 0:20:45About 300.
0:20:45 > 0:20:47- Reds, what do you think?- None.
0:20:47 > 0:20:50There's a big old difference going on here.
0:20:50 > 0:20:54Let's see what happens. Carry on with the experiment.
0:20:56 > 0:20:57Here we go.
0:20:57 > 0:21:03Will 756 eggs hold the weight of a 1,000kg helicopter?
0:21:05 > 0:21:08The wind not making life easy for the pilot.
0:21:08 > 0:21:12But it's getting closer.
0:21:12 > 0:21:14Centimetres away now.
0:21:15 > 0:21:18Incredibly, I think they may have done it.
0:21:18 > 0:21:19With the chopper landed,
0:21:19 > 0:21:22the eggs are now supporting its entire weight.
0:21:32 > 0:21:35As you can see, it worked.
0:21:35 > 0:21:39The lab rats worked out how many eggs
0:21:39 > 0:21:42could support a 1,000kg helicopter.
0:21:42 > 0:21:44Lift this off. Let's just make sure.
0:21:45 > 0:21:47Not an egg broken.
0:21:47 > 0:21:52Our new strength hero is scientifically proven to be the egg.
0:21:52 > 0:21:55CHEERING AND APPLAUSE
0:21:55 > 0:21:56A point to the Reds.
0:21:56 > 0:21:58Well done.
0:21:58 > 0:22:00Really, that was amazing.
0:22:00 > 0:22:02Who'd have thought
0:22:02 > 0:22:06that the heli-egg pad would survive? I hate to say this, but...
0:22:06 > 0:22:08lab rat, come over here.
0:22:08 > 0:22:11This is a weird experience for us both.
0:22:11 > 0:22:14Well done. I'm really proud of you.
0:22:14 > 0:22:16All right, don't get giddy.
0:22:16 > 0:22:18Well, that was...
0:22:18 > 0:22:21If I ever get round to inventing my wind-powered helicopter,
0:22:21 > 0:22:23that heli-egg pad will be handy.
0:22:23 > 0:22:26Where is the heli-egg pad now? Where is it?
0:22:28 > 0:22:31What a fantastic success!
0:22:31 > 0:22:33The lab rats haven't ruined it with their stupidity.
0:22:33 > 0:22:35CAR HORN
0:22:35 > 0:22:42No, they've ruined it. Just when I thought we were making progress.
0:22:48 > 0:22:49Idiot!
0:22:49 > 0:22:53That was the first thing you ever got right and you messed it up.
0:22:53 > 0:22:56I hope you cleaned that mess up.
0:22:56 > 0:23:00You didn't put it in there, did you? You could have made a good omelette.
0:23:00 > 0:23:05It would have been useful. Go and get ready. It's now time for...
0:23:09 > 0:23:13The teams have to get these prize pods from this side of the tank,
0:23:13 > 0:23:18using the bungee-powered catapults to launch them into the prize zone
0:23:18 > 0:23:21on the other side of the tank, but there's a twist.
0:23:21 > 0:23:24One person from each team is in the gunge.
0:23:24 > 0:23:27They're here to intercept the other team's pods
0:23:27 > 0:23:31and return their own pods to the bungee loaders and firers.
0:23:31 > 0:23:33Each team can also fire...
0:23:33 > 0:23:38these to their team mates in the gunge.
0:23:38 > 0:23:42- These are...- Giant hands of glory!
0:23:42 > 0:23:43Stop showing off.
0:23:43 > 0:23:44Away you go.
0:23:44 > 0:23:47These can be used to stop pods because they're bigger.
0:23:47 > 0:23:52In the time it takes to fire one of these,
0:23:52 > 0:23:56you could have fired a prize pod, so you're wasting time.
0:23:56 > 0:23:58Red Team, you're in the lead.
0:23:58 > 0:24:03You get a five-second head start. You can go on the first siren.
0:24:03 > 0:24:06You have some time to get prize pods into the prize zone
0:24:06 > 0:24:07and that time starts...
0:24:07 > 0:24:09now!
0:24:09 > 0:24:13So the Red Team the first to try to catapult themselves some prizes
0:24:13 > 0:24:16to take home. They've gone straight for the hands of glory.
0:24:17 > 0:24:21The Yellows have started and Ashley's wasting no time
0:24:21 > 0:24:23powering those prize pods across the gunge.
0:24:23 > 0:24:26The firer is still trying to find their range.
0:24:29 > 0:24:32The blockers are on top at the moment, but look at that,
0:24:32 > 0:24:37the Reds have a prize pod bounce in and out of the prize zone.
0:24:37 > 0:24:39The Yellows score.
0:24:39 > 0:24:41The Red Team are firing pods at their own teammate.
0:24:43 > 0:24:46That's more like it! The Reds equalise.
0:24:49 > 0:24:51Now the Yellows are at it.
0:24:51 > 0:24:54Ashley just pinged a pod in Jamila's face.
0:24:54 > 0:24:58Still, everything to play for and another Red pod in the zone.
0:24:58 > 0:25:01The Yellows had better do something fast.
0:25:01 > 0:25:04You never know when time may run out.
0:25:06 > 0:25:08KLAXON
0:25:11 > 0:25:13That's time up. Wow! What a battle.
0:25:13 > 0:25:16Teams, come round here, please. Red and Yellow.
0:25:16 > 0:25:20Obviously not you guys. You're stuck in there.
0:25:20 > 0:25:23Let's find out who's won. Lab rats, count them up.
0:25:23 > 0:25:25Yellows, what have we got? One.
0:25:25 > 0:25:28And the Reds. What have we got?
0:25:28 > 0:25:30Two, the Reds are the winners.
0:25:30 > 0:25:32CHEERING AND APPLAUSE
0:25:32 > 0:25:35Well done.
0:25:35 > 0:25:40Reds, let's have a look at what you've won.
0:25:40 > 0:25:43A make-your-own racing car.
0:25:43 > 0:25:44A Transformer.
0:25:45 > 0:25:49Yellows, this is the difficult bit where we have to look at
0:25:49 > 0:25:51what you would have won, but haven't.
0:25:51 > 0:25:53What is it?
0:25:53 > 0:25:55A make-your-own racing car.
0:25:55 > 0:25:57Sorry, team.
0:25:57 > 0:26:00Only one team can go home with their prizes.
0:26:00 > 0:26:02The other team goes home
0:26:02 > 0:26:05with their memories of the prizes which they're about to blow up.
0:26:05 > 0:26:08Sorry, cos it's time for Bidet Goes Bang.
0:26:13 > 0:26:15CHEERING
0:26:17 > 0:26:19Reds, well done, Reds.
0:26:19 > 0:26:21These are your prizes. Congratulations.
0:26:21 > 0:26:23You are our winners. Well played.
0:26:23 > 0:26:26CHEERING
0:26:26 > 0:26:30And so, as they disappear, Yellows,
0:26:30 > 0:26:33we must make our way over there.
0:26:33 > 0:26:34Come with me.
0:26:34 > 0:26:37Come on. This way.
0:26:37 > 0:26:39We must go...
0:26:44 > 0:26:47It's a sad moment. What can I say?
0:26:47 > 0:26:49Somebody had to go home with an armful of prizes
0:26:49 > 0:26:51and somebody had to blow them up.
0:26:51 > 0:26:55You're doing the blowing up. Team, lift the plunger.
0:26:55 > 0:26:58There we go. Countdown, audience,
0:26:58 > 0:27:03from five, four, three, two, one.
0:27:03 > 0:27:04Go!
0:27:04 > 0:27:06CHEERING
0:27:06 > 0:27:09Yellows, well done.
0:27:09 > 0:27:11Did that make it worth it?
0:27:11 > 0:27:13Yeah, it kind of did.
0:27:13 > 0:27:18Today has been an eggs-traordinary look at the power of the humble egg.
0:27:18 > 0:27:21There are lots of eggs left unbroken which gives me the opportunity
0:27:21 > 0:27:25for some target practice. Lab rats, you may want to get your goggles on.
0:27:25 > 0:27:27In the meantime, bye for now.
