0:00:29 > 0:00:33CHEERING AND APPLAUSE
0:00:38 > 0:00:40Ah. That is awkward.
0:00:40 > 0:00:41CHEERING AND APPLAUSE
0:00:41 > 0:00:45It's OK. I didn't want the door open more than that, anyway.
0:00:45 > 0:00:47Hello! I'm Richard. Welcome to my Blast Lab.
0:00:47 > 0:00:51CHEERING AND APPLAUSE
0:00:51 > 0:00:53OK, my protective lab coat.
0:00:55 > 0:01:00Actually, don't be put off by the name "Blast Lab".
0:01:00 > 0:01:02It is perfectly safe. There's only one thing
0:01:02 > 0:01:05more important than your safety and that's my safety.
0:01:05 > 0:01:08In a moment, I shall bring in two teams to play some games
0:01:08 > 0:01:11and win some prizes, all in the name of science.
0:01:11 > 0:01:12Let's see what's in store.
0:01:30 > 0:01:32Usually, this lab is kept secure
0:01:32 > 0:01:35by a group of the toughest SAS men in the country.
0:01:35 > 0:01:38But they've all entered a cake-baking competition,
0:01:38 > 0:01:39so they can't be here.
0:01:39 > 0:01:43However, my nan got barred last year when she controversially came second
0:01:43 > 0:01:46and took out the mayor with a scissor kick.
0:01:46 > 0:01:49Instead, she's here defending the lab. It is my Ninja Nan.
0:01:49 > 0:01:52CHEERING AND APPLAUSE
0:01:59 > 0:02:04Some moves. Why does the door always work for you? Anyway, Ninja Nan,
0:02:04 > 0:02:07thanks for standing in. It's great to have you here.
0:02:07 > 0:02:10She may look fragile but she is in fact a fully-trained ninja.
0:02:10 > 0:02:13SMACK! WHACK! THWACK!
0:02:15 > 0:02:17Nan, if you take your place in security, please.
0:02:17 > 0:02:22Take your place in security. Thank you. Hearing's not brilliant.
0:02:22 > 0:02:23She is quick though.
0:02:23 > 0:02:26So fast she went out for a jog this morning and set off a speed camera.
0:02:26 > 0:02:29Maybe she doesn't want any more points on her licence.
0:02:29 > 0:02:33That's why she's taking it easy in here. Nan, have you settled in?
0:02:33 > 0:02:35She's there with her trolley.
0:02:35 > 0:02:38See the ninja way she parks that trolley. It's terrifying.
0:02:38 > 0:02:41Has she got her sandwiches again?
0:02:41 > 0:02:44Oh no, knitting! Yeah, she's been knitting herself
0:02:44 > 0:02:47a pair of ninja mittens so she can fight in the winter.
0:02:47 > 0:02:50Let's have a look at who's trying to get in my lab today.
0:02:50 > 0:02:52CHEERING AND APPLAUSE
0:02:55 > 0:02:57Now, you see, you say you're the Yellow Team.
0:02:57 > 0:03:00We can't let just anybody in here. My top-secret lab.
0:03:00 > 0:03:03We have to make sure, so I have my security files.
0:03:03 > 0:03:05Identify yourselves please by name.
0:03:05 > 0:03:08Brittany! Anne-Marie! Harriet!
0:03:08 > 0:03:12Good Lord. OK, those are your names. Well, that checks out with the form.
0:03:12 > 0:03:15It says here there's a hidden talent.
0:03:15 > 0:03:19Anne-Marie, what can you do to prove that your who you say you are?
0:03:19 > 0:03:21I can speed talk, like, talk really fast.
0:03:21 > 0:03:27SHE TALKS VERY QUICKLY
0:03:27 > 0:03:29Enough, enough! I believe you.
0:03:29 > 0:03:32That is speed talking. You are the Yellow Team.
0:03:32 > 0:03:34You are through security. Come on into the lab.
0:03:34 > 0:03:36CHEERING AND APPLAUSE
0:03:40 > 0:03:41Hello, team. You're through security,
0:03:41 > 0:03:43you are the Yellow Team. Where are you from?
0:03:43 > 0:03:47ALL: We're from London and we're the Pink Panthers!
0:03:47 > 0:03:49You've come up with your own name!
0:03:49 > 0:03:51But you're the Yellow Team for today.
0:03:51 > 0:03:54Let's find out who's claiming to be the Red Team.
0:03:54 > 0:03:56CHEERING AND APPLAUSE
0:03:59 > 0:04:01These three say they are the Red Team.
0:04:01 > 0:04:04Identify yourselves by names, so I can check you out. You are?
0:04:04 > 0:04:07Oscar! Theodore! Ambrose!
0:04:07 > 0:04:10Well, that does check out. That's who it's got down here.
0:04:10 > 0:04:13- What is your hidden talent?- Diablo.
0:04:15 > 0:04:20So, this is Ambrose. It's a spinning thing on a stick.
0:04:20 > 0:04:22That's amazing, actually.
0:04:22 > 0:04:25OK, well, that does check out with your hidden talent on my form.
0:04:25 > 0:04:28Good grief. Right, you are the Red Team.
0:04:28 > 0:04:31You can come on through security, past Ninja Nan.
0:04:31 > 0:04:33CHEERING AND APPLAUSE
0:04:33 > 0:04:37Nice to see you, Red Team. Where are you from?
0:04:37 > 0:04:40We're from Devon and we are the Lords of Science!
0:04:40 > 0:04:43Nope, you're the Red Team but welcome to the laboratory.
0:04:43 > 0:04:45It's time for both teams to get into position
0:04:45 > 0:04:46ready for the first game.
0:04:46 > 0:04:49You know where to go. Over there, please. Get set up and ready.
0:04:49 > 0:04:53I'd like to introduce a friend who's been driving me up the wall,
0:04:53 > 0:04:55which is only because I fitted him
0:04:55 > 0:04:58with some special wall-climbing tyres. It is Oliver.
0:05:15 > 0:05:17CHEERING AND APPLAUSE
0:05:17 > 0:05:20Oliver loves to collect facts to store in his hi-tech,
0:05:20 > 0:05:22sophisticated Fact Nav system.
0:05:22 > 0:05:24The problem is, they're not always correct.
0:05:24 > 0:05:28I am going to read both teams a science fact and they have
0:05:28 > 0:05:30to tell me whether it is true or false.
0:05:30 > 0:05:33If it's true, Oliver will let us know by doing this.
0:05:33 > 0:05:36HORN BEEPS
0:05:36 > 0:05:38And if it's false, Oliver will do this.
0:05:38 > 0:05:40FOG HORN BLASTS
0:05:40 > 0:05:43We understand the rules here, do we?
0:05:43 > 0:05:45Red Team, you're going first.
0:05:45 > 0:05:48Here is your science fact from Oliver's Fact Nav.
0:05:48 > 0:05:50Gold is found in sea water?
0:05:50 > 0:05:54Is that true or is that false? Don't answer straight away.
0:05:54 > 0:05:57You can have a chat and a think. Sort it out between you.
0:05:57 > 0:06:00They're having a big talk. Audience, what do we think?
0:06:00 > 0:06:02Gold is found in sea water, true or false?
0:06:02 > 0:06:04MOST SHOUT: False!
0:06:04 > 0:06:07False, false... Nearly everybody false.
0:06:07 > 0:06:10One little girl there saying... You think it's true?
0:06:10 > 0:06:13The audience is almost unanimous saying it's false.
0:06:13 > 0:06:17But you don't have to go with them. Have your own thoughts about this.
0:06:17 > 0:06:19- What do you think? - We think it's true.
0:06:19 > 0:06:21True? Going against the entire audience
0:06:21 > 0:06:23apart from this little girl,
0:06:23 > 0:06:25who wants sea water, cos it will be full of gold.
0:06:25 > 0:06:28Oliver, tell us, is it true or is it false?
0:06:28 > 0:06:31HORN BEEPS
0:06:31 > 0:06:32CHEERING
0:06:32 > 0:06:36So, that's a point for you. In actual fact, although it's there,
0:06:36 > 0:06:39no effective process has ever been designed
0:06:39 > 0:06:41to extract the gold from the oceans.
0:06:41 > 0:06:45Which is a shame. Because if it were all mined, every person here
0:06:45 > 0:06:48would get 20 kilograms of gold.
0:06:48 > 0:06:51Sadly, we can't get it in. Never mind. Right, Yellows,
0:06:51 > 0:06:53you've seen how it's done. It's your turn.
0:06:53 > 0:06:55Here is your science fact.
0:06:55 > 0:06:57Is this true or false?
0:06:57 > 0:07:02The first hot air balloon passengers were a dog, a cat and a mouse.
0:07:02 > 0:07:05Is that true or is that false?
0:07:05 > 0:07:07Have a chat and work it out.
0:07:07 > 0:07:10Don't know about you, sounds like a bad cartoon to me.
0:07:10 > 0:07:13A dog, a cat and a mouse in a hot air balloon.
0:07:13 > 0:07:16Audience, what do we think? Is it true or is it false?
0:07:16 > 0:07:19SHOUTING IN RESPONSE
0:07:19 > 0:07:21A lot of falses here. A couple of trues down here.
0:07:21 > 0:07:23You think it's true.
0:07:23 > 0:07:26You think they were a dog, cat and a mouse. Yellow Team,
0:07:26 > 0:07:30the most important people here, for their opinion. What do you think?
0:07:30 > 0:07:32- We think it's false.- False?
0:07:32 > 0:07:36The first hot air balloon passengers weren't a dog, a cat and a mouse.
0:07:36 > 0:07:38Oliver, is it true or is it false?
0:07:38 > 0:07:40FOG HORN BLASTS
0:07:40 > 0:07:43Well done! That's a point for you.
0:07:43 > 0:07:45CHEERING AND APPLAUSE
0:07:45 > 0:07:47- Do you know what they were?- No.
0:07:47 > 0:07:51They were actually a sheep, duck and a cockerel. They were!
0:07:51 > 0:07:53In 1783. The flight lasted eight minutes
0:07:53 > 0:07:56and they were the first balloon passengers.
0:07:56 > 0:08:00Right, here is your final question. This one works a bit differently.
0:08:00 > 0:08:02I don't want you to tell me true or false.
0:08:02 > 0:08:05I want you to answer it, write down your answer
0:08:05 > 0:08:07on that board, then we'll hold them up and look.
0:08:07 > 0:08:10I should say, it might be quite difficult.
0:08:10 > 0:08:12So, I'm going to be nice.
0:08:12 > 0:08:15I don't expect you to get the exact answer. There will be a point
0:08:15 > 0:08:18for the team who gets closest to the exact answer.
0:08:18 > 0:08:21Understand the rules? For both teams then -
0:08:21 > 0:08:25How many text messages are sent in the UK every day?
0:08:25 > 0:08:28Not just by each of you but by the whole UK.
0:08:28 > 0:08:31Have a think. Anybody in the audience got an idea?
0:08:31 > 0:08:33Don't shout it out, I'll talk to you with my...
0:08:33 > 0:08:36I designed this myself. Looks like a mug tree.
0:08:36 > 0:08:38It's got a hidden microphone in it.
0:08:38 > 0:08:40Any ideas? How many text messages sent in the UK?
0:08:40 > 0:08:44- Are they all sent by you? - No. 500 million.
0:08:44 > 0:08:45500 million! That's lots.
0:08:45 > 0:08:49- Somebody down there, come forward. - 6 million.- What?- 6 million.
0:08:49 > 0:08:52Are you basing that on scientific evidence
0:08:52 > 0:08:54- or is it a big guess? - It's a big guess.
0:08:54 > 0:08:57Does anybody happen to actually know that fact?
0:08:57 > 0:09:00What about here? My gold-in-sea-water friend.
0:09:00 > 0:09:02You really wanted gold to be in the sea water.
0:09:02 > 0:09:08I think, erm...
0:09:08 > 0:09:097 million and a half.
0:09:09 > 0:09:14OK. Has anybody got any other answers? Anybody disagree wildly?
0:09:14 > 0:09:16- What you think, Oliver?- 28,000.
0:09:16 > 0:09:1828,000? That's a lot less.
0:09:18 > 0:09:21We're getting a range of answers from the audience.
0:09:21 > 0:09:24A range of answers. Let's see if both teams are ready, then.
0:09:24 > 0:09:27Reds, have you written down an answer?
0:09:27 > 0:09:29Yellows, I'll have to hurry you. You have some time.
0:09:29 > 0:09:33You've got a bit less time. A lot less time now. No time now.
0:09:33 > 0:09:36Let's have a look at your answers. Red and Yellow.
0:09:36 > 0:09:38Reds are saying 3 million.
0:09:38 > 0:09:41Yellows are saying 25 million.
0:09:41 > 0:09:42The actual answer...
0:09:43 > 0:09:47Around 207 million every day.
0:09:47 > 0:09:49That means the Yellows get an extra point.
0:09:49 > 0:09:52So that is another point to the Yellows.
0:09:52 > 0:09:54Yellows are in the lead. Well done.
0:10:16 > 0:10:18CHEERING AND APPLAUSE
0:10:18 > 0:10:21That's all to come. Right now, it's time for Mini Science,
0:10:21 > 0:10:25the round where our contestants use ordinary, everyday objects
0:10:25 > 0:10:27to solve extraordinary science problems.
0:10:27 > 0:10:30I made a time machine out of household objects
0:10:30 > 0:10:32and used it to bring back my old science teacher.
0:10:32 > 0:10:33But it went about wrong.
0:10:33 > 0:10:35She came back as a 10-year-old.
0:10:35 > 0:10:38I've always looked up to her, but now,
0:10:38 > 0:10:40even I have to look down to her.
0:10:40 > 0:10:41It is Mini Miss!
0:10:44 > 0:10:46- Hello, Miss.- Hello, Richard.
0:10:46 > 0:10:49So, what are we doing today?
0:10:49 > 0:10:53- Well, today's teams are going to be playing leaf-blower catch.- Right.
0:10:53 > 0:10:58It's basically a game of catch but one team member operates
0:10:58 > 0:10:59the adjustable leaf-blower.
0:10:59 > 0:11:02Another has a pile of beach balls to throw
0:11:02 > 0:11:04into the vertical airstream from the blower.
0:11:04 > 0:11:07and the third stands on a platform above the blower.
0:11:07 > 0:11:11The one on the raised platform has to catch the beach balls in a giant net.
0:11:11 > 0:11:15OK, so we're going to need catchers to do this.
0:11:15 > 0:11:18- Who are the catchers?- Me.- Woo!
0:11:18 > 0:11:22OK. It's Britney and Theodore? Go out through that door there,
0:11:22 > 0:11:25make your way round to the gantry and take your positions.
0:11:25 > 0:11:28Away you go. Don't get lost back there in the Blast Lab.
0:11:28 > 0:11:31This is about air pressure, isn't it?
0:11:31 > 0:11:34That's correct, Richard. Well remembered.
0:11:34 > 0:11:36- Thank you.- Now, everybody, ear defenders on.
0:11:36 > 0:11:38Right, OK, will do.
0:11:38 > 0:11:41That includes you, Oliver.
0:11:41 > 0:11:42HORN TOOTS
0:11:42 > 0:11:45- So, are we ready for this?- Pardon? - Are we ready?- Pardon?
0:11:45 > 0:11:49- SHOUTS:- Are we ready for this? Are we ready for this, Miss?
0:11:49 > 0:11:52- Yes.- Pardon? - SHOUTS: Yes, Richard!
0:11:52 > 0:11:56Right, OK. Catchers, are you ready? Catchers, are you...?
0:11:56 > 0:12:00Oh. We didn't think of this. Lab rats, are they ready?
0:12:00 > 0:12:01- SHOUTS:- Lab rats! Can I have that?
0:12:01 > 0:12:03Why did you even bring this?
0:12:03 > 0:12:06Lab rat...
0:12:06 > 0:12:08Are they ready? Good, right.
0:12:08 > 0:12:11There's another point at stake for the winning team.
0:12:11 > 0:12:14Yellows in the lead. Reds could catch up and equalise.
0:12:14 > 0:12:18OK, you have some time, if you can hear me,
0:12:18 > 0:12:23to catch as many balls as you can. Can you hear me? Good.
0:12:23 > 0:12:25Well, your time starts now.
0:12:25 > 0:12:27CHEERING AND APPLAUSE
0:12:41 > 0:12:43Special microphone. That's better!
0:12:43 > 0:12:47These leaf-blowers create a column of fast-moving air.
0:12:47 > 0:12:51The thing is, if they get this right, that column is where the ball
0:12:51 > 0:12:55wants to be because that column is an area of low pressure.
0:12:55 > 0:12:57That is where things like to stay.
0:12:57 > 0:13:00So the beach balls will stay
0:13:00 > 0:13:02eventually in the column of fast moving air.
0:13:02 > 0:13:06That means they'll move up to the basket, they can be controlled.
0:13:06 > 0:13:08Spheres are best for this as they have no edges,
0:13:08 > 0:13:12so air can flow easily around them. This effect was first noticed
0:13:12 > 0:13:14by a clever scientist called Bernoulli.
0:13:14 > 0:13:16So it's known as The Bernoulli Principle.
0:13:16 > 0:13:19You can see it in action.
0:13:20 > 0:13:24I bet Mr Bernoulli never had this much fun with a leaf blower
0:13:24 > 0:13:25and a shed load of beach balls.
0:13:34 > 0:13:37The teams need to be quick because you never know
0:13:37 > 0:13:39when "some time" might run out.
0:13:42 > 0:13:46The Reds have taken a slight lead, but don't write off the Yellows.
0:13:53 > 0:13:55END-OF-ROUND SIREN WAILS
0:13:55 > 0:13:57Sorry, that last one can't go in.
0:13:57 > 0:13:59Can I hand that back to my assistant?
0:13:59 > 0:14:01OK, everybody, ear-defenders off.
0:14:01 > 0:14:05- SHOUTS:- I said, ear-defenders...! We didn't think of this.
0:14:05 > 0:14:09Ear-defenders off! Right, thank you. It's time to see which team...
0:14:09 > 0:14:11I'm still shouting!
0:14:11 > 0:14:13Which team has bagged the most balls.
0:14:13 > 0:14:16Thank you, Miss. Thank you. I don't need to shout to you...
0:14:16 > 0:14:19Right, it's time to see which team has bagged the most balls.
0:14:19 > 0:14:22The Yellow Team - how many do we have here?
0:14:23 > 0:14:2610, 16! Are you sure, Lab Rat?
0:14:26 > 0:14:2916 for Yellow. For Reds, this could be your equaliser
0:14:29 > 0:14:33if you get this point. If not, it puts the Yellows further ahead.
0:14:33 > 0:14:35How many for the Reds?
0:14:35 > 0:14:3610...20. Whoa!
0:14:36 > 0:14:39That's an equalising point for the Reds!
0:14:41 > 0:14:43Two all.
0:14:43 > 0:14:48That experiment made me realise how strong air can be
0:14:48 > 0:14:51and it's given me a brilliant idea.
0:14:51 > 0:14:55Maybe you could use air instead of petrol to power cars.
0:14:55 > 0:14:59Today, at our top-secret Lab Rat test zone,
0:14:59 > 0:15:04we're going to see if we can power a car by a wind alone.
0:15:06 > 0:15:08Unfortunately for this Lab Rat,
0:15:08 > 0:15:12the only car available for this experiment is his pride and joy.
0:15:12 > 0:15:16A 1992 Ford Fiesta.
0:15:16 > 0:15:20He absolutely loves that car.
0:15:20 > 0:15:23Not sure why, because it doesn't work.
0:15:23 > 0:15:28So, we're going to make a few, how should I put this, modifications.
0:15:35 > 0:15:38Now, I wouldn't do this to your dad's car,
0:15:38 > 0:15:40but it's only a Lab Rat. He won't mind.
0:15:40 > 0:15:42MUSIC: "Club Foot" by Kasabian
0:15:48 > 0:15:51With the roof off, we need an expert.
0:15:51 > 0:15:54Hello, I'm a kite surfing expert.
0:15:57 > 0:15:58Our expert sets to work
0:15:58 > 0:16:01attaching his high-performance kite to the car.
0:16:01 > 0:16:06A large kite this size can speed a kite-board to over 40 mph.
0:16:06 > 0:16:10But a kite-board is lighter and highly manoeuvrable.
0:16:10 > 0:16:13Can a kite pull a one-tonne car?
0:16:13 > 0:16:18A kite works because things like to move into areas of low pressure.
0:16:18 > 0:16:22The theory goes that when air flows past a kite,
0:16:22 > 0:16:24it produces low pressure above the kite
0:16:24 > 0:16:25and high pressure below it.
0:16:25 > 0:16:27The high pressure pushes the kite
0:16:27 > 0:16:30towards low pressure, lifting it up.
0:16:30 > 0:16:33The power of the wind also pushes the kite forwards.
0:16:33 > 0:16:36So, by putting the kite at the correct angle,
0:16:36 > 0:16:40our Lab Rats should be able to make it pull them and their car along.
0:16:45 > 0:16:46This is now a grudge match,
0:16:46 > 0:16:50as that Lab Rat has found a child's bike from somewhere,
0:16:50 > 0:16:55and wants revenge in the form of a race against the wind-powered car.
0:16:58 > 0:17:04It's a battle of the eco-energies, as wind power takes on man's muscle.
0:17:05 > 0:17:06HE HONKS HORN
0:17:06 > 0:17:09OK, let's check if you were paying attention there.
0:17:09 > 0:17:14Red Team, for an extra point, which you think is going to win the race?
0:17:14 > 0:17:17The bike or the wind-powered car?
0:17:17 > 0:17:20Have a think about it. Yellow Team, same question to you.
0:17:20 > 0:17:23There is an extra point at stake here, which is needed right now.
0:17:23 > 0:17:24Which is going to win?
0:17:24 > 0:17:26Bike or wind-powered car?
0:17:28 > 0:17:29OK, I want an answer from you.
0:17:29 > 0:17:33- Have you made up your answers? Made up your minds?- We say bike.
0:17:33 > 0:17:39- Why?- Because the car is too heavy to be pulled by the wind.
0:17:39 > 0:17:42And you need a lot of wind.
0:17:42 > 0:17:47But the bike is being powered by a Lab Rat. They're a bit stupid.
0:17:47 > 0:17:49Yeah, but at least he knows how to ride a bike.
0:17:49 > 0:17:54You reckon a Lab Rat stands a better chance than...
0:17:54 > 0:17:55OK, fine. Yellows?
0:17:55 > 0:18:01- The car.- You think the car's going to win? So, bike, car.
0:18:01 > 0:18:04- Why?- Because we think it was going to be the bike,
0:18:04 > 0:18:06but the car is, like...
0:18:06 > 0:18:09You wouldn't have shown it us if you didn't have a reason.
0:18:09 > 0:18:13Ah, so now we're introducing us into the science.
0:18:13 > 0:18:14We are Blast Lab. We've no idea.
0:18:14 > 0:18:18So, you think the car. You think the bike. Audience, what do we reckon?
0:18:18 > 0:18:20What do we reckon? Car or bike?
0:18:20 > 0:18:23- Car or bike? What do you think down there?- Bike.
0:18:23 > 0:18:25Bike. What do we think down here?
0:18:25 > 0:18:27- Bike.- Bike.- Car.
0:18:27 > 0:18:30Car. So, you disagree. Why do you think the bike?
0:18:30 > 0:18:32Because the car is too heavy.
0:18:32 > 0:18:35Well, cars don't generally have sails, do they?
0:18:35 > 0:18:37There must be a reason. What do you think?
0:18:37 > 0:18:39I think the car will definitely win.
0:18:39 > 0:18:42Because the wind can get very strong for the car.
0:18:42 > 0:18:44If you're sitting on a skateboard or something
0:18:44 > 0:18:47and then a kite, it will get you over 60,
0:18:47 > 0:18:49so imagine what it would do to a car.
0:18:49 > 0:18:52Well, people do that, don't they? With the kite and the skateboard.
0:18:52 > 0:18:54He has a point. One more answer.
0:18:54 > 0:18:57I think bike because there's no way that a kite can pull a car.
0:18:57 > 0:18:59There is a lot of weight in the car.
0:18:59 > 0:19:02Well, there's only one way to find out and that is to watch it.
0:19:02 > 0:19:04Let's have a look.
0:19:07 > 0:19:09The kite-car is moving, but it's slow off the mark
0:19:09 > 0:19:12and the bike has sped into the lead.
0:19:12 > 0:19:16With the wind behind them, the car is gaining ground.
0:19:17 > 0:19:20They are neck and neck at the halfway point
0:19:20 > 0:19:23and our Lab Rat can't keep up the pace.
0:19:25 > 0:19:28The kite-car is breezing to victory.
0:19:42 > 0:19:43ALL: Woo hoo! Yeah!
0:19:43 > 0:19:45There you go. I'm sorry, Reds.
0:19:45 > 0:19:47Yellows, an extra point to you.
0:19:50 > 0:19:54Yellow Team, well done. Reds, I'm sorry.
0:19:54 > 0:19:57You're back to losing. You backed a Lab Rat, what did you expect?
0:19:57 > 0:20:00Time to move on. That means both teams must now leave.
0:20:00 > 0:20:03You've got to get changed for the Messy Messy Mess Test.
0:20:03 > 0:20:05You need your protective suits on.
0:20:05 > 0:20:07While they're doing that,
0:20:07 > 0:20:10I'd just like to watch a bit of that tape again.
0:20:10 > 0:20:13I want to see the bit where the Lab Rat's on a bicycle.
0:20:13 > 0:20:15This bit. Look at him!
0:20:15 > 0:20:18Look at that. Pathetic spectacle.
0:20:18 > 0:20:21It's pitiful. He let Blast Lab down,
0:20:21 > 0:20:23he let the Red Team down, as it turned out.
0:20:23 > 0:20:26I can't believe he let us all down badly.
0:20:26 > 0:20:29I've concocted the perfect punishment.
0:20:29 > 0:20:32I've got him powering the whole lab by bicycle power.
0:20:35 > 0:20:37Pedal faster, please...
0:20:37 > 0:20:38Faster.
0:20:38 > 0:20:42Put your back into it, Lab Rat. Thank you.
0:20:42 > 0:20:45While he's busy doing that, it's time for us to move on
0:20:45 > 0:20:47to the Messy Messy Mess Test.
0:20:49 > 0:20:52Which today is in the nuclear box,
0:20:52 > 0:20:55and that is why you guys need protective suits.
0:20:55 > 0:20:59Be careful in there. Interesting thing, I was eating a sandwich
0:20:59 > 0:21:01last night and I dropped a prawn.
0:21:01 > 0:21:05I couldn't find it... Yeah, I have.
0:21:05 > 0:21:06Yeah, it's grown.
0:21:06 > 0:21:08That does happen.
0:21:08 > 0:21:10When I say I dropped one,
0:21:10 > 0:21:12I kind of dropped the whole sandwich in,
0:21:12 > 0:21:14so don't touch anything.
0:21:14 > 0:21:16Not sure if they bite.
0:21:16 > 0:21:18Probably do. This is the game.
0:21:18 > 0:21:22Each pod contains fabulous prizes like night-vision goggles,
0:21:22 > 0:21:26a football-playing robot and a Blood, Bones And Body Bits Kit.
0:21:26 > 0:21:29The idea is to move these pods from this end of the box.
0:21:29 > 0:21:32Obviously you can't use your hands because they'd melt.
0:21:32 > 0:21:34That's why you've got these tongs.
0:21:34 > 0:21:37Pass them one to another. If you drop them it's out of play.
0:21:37 > 0:21:40Get it to the end and drop them in the basket.
0:21:40 > 0:21:43The team to move the most prizes across the nuclear box
0:21:43 > 0:21:44gets to take them home.
0:21:44 > 0:21:47The losing team has to blow theirs up.
0:21:47 > 0:21:50Yellow Team, you start first
0:21:50 > 0:21:54because you have the most points, giving a five-second advantage.
0:21:54 > 0:21:56When you hear the first nuclear alert you can start.
0:21:56 > 0:22:01Red Team, you can only begin when we hear the second nuclear alert.
0:22:01 > 0:22:05You've got some time to get as many of these pods across the box
0:22:05 > 0:22:07and into the basket as possible.
0:22:07 > 0:22:09If you drop a pod, remember it is out of play.
0:22:09 > 0:22:11Pick up another one and start again.
0:22:11 > 0:22:15We will be watching, trust me. Hang on. I know what that is.
0:22:15 > 0:22:19Lab Rat, pedal, pedal! Thank you.
0:22:19 > 0:22:22Keep pedalling for the rest of this.
0:22:22 > 0:22:26Yellow Team, your time starts now.
0:22:26 > 0:22:28'Off we go in search of the gungy prize pods.
0:22:31 > 0:22:35'There's the second siren, so the Reds are up and running.
0:22:40 > 0:22:44'The Yellows are struggling with the changeover,
0:22:44 > 0:22:46'but the Reds bag their first pod.
0:22:46 > 0:22:49'Yellows still making hard work of the first changeover.
0:22:49 > 0:22:51'Oh, that's bad news.'
0:22:51 > 0:22:55I don't like to see anything coming out of the nuclear box
0:22:55 > 0:22:57because sometimes late at night
0:22:57 > 0:22:59it's not prize pods,
0:22:59 > 0:23:04but other things that come out.
0:23:04 > 0:23:06'The Yellows still haven't got the hang of this.
0:23:06 > 0:23:09'Oh, no, Harriet's hat's fallen off.
0:23:09 > 0:23:12'While that's going on, the Reds are getting another.'
0:23:12 > 0:23:15Red Team are doing very well indeed.
0:23:15 > 0:23:17Yellow Team struggling with this.
0:23:17 > 0:23:21It is very difficult. I hope they're not tempted to use their hands
0:23:21 > 0:23:23because then there will be no hands. Messy.
0:23:23 > 0:23:27'The Reds looking like nuclear robots out there,
0:23:27 > 0:23:30'dunking pretty much every prize pod in the basket.
0:23:31 > 0:23:34'Look at that, the Yellow prize pods have floated over
0:23:34 > 0:23:36'to the Red side of the tank.
0:23:36 > 0:23:40'The Reds have nearly bagged all the prize pods.
0:23:40 > 0:23:42'They're going to clear us out at this rate.
0:23:44 > 0:23:49'How long's left? Who knows with my confusing "some time" clock?
0:23:49 > 0:23:52'The Yellow Team had a five-second head-start
0:23:52 > 0:23:54'but they look to have blown it.'
0:23:57 > 0:23:59END-OF-ROUND SIREN
0:23:59 > 0:24:02CHEERING AND APPLAUSE
0:24:02 > 0:24:04That is it. Your time is up.
0:24:04 > 0:24:08It's time for us to find out which one of you has won.
0:24:08 > 0:24:09I think it's fairly obvious.
0:24:09 > 0:24:13I won't count there myself because if I touch them my hands melt.
0:24:13 > 0:24:16They've got special nuclear-proof paws. How many?
0:24:16 > 0:24:20One. Well done. That's as far as this Lab Rat can count.
0:24:20 > 0:24:24Lab Rat, how many in there? I know it's a strain, work it out.
0:24:24 > 0:24:27Eight points for the Red Team! They are the winners!
0:24:27 > 0:24:30CHEERING AND APPLAUSE
0:24:30 > 0:24:33So, Red Team, let's take a look at what you've won.
0:24:33 > 0:24:36For that I need the help of my specially-trained Ninja Nan.
0:24:36 > 0:24:39These are the prizes. Let's see what you've got.
0:24:39 > 0:24:40Lab Rat is taking the prizes out.
0:24:40 > 0:24:45You've each got a pair of night-vision goggles.
0:24:45 > 0:24:49You've each got an atomic telescope!
0:24:49 > 0:24:52A football robot each. Well done, well done.
0:24:52 > 0:24:55Ninja Nan, if you'd like to model the football robot.
0:24:55 > 0:24:57If you can find the football robot...
0:24:57 > 0:25:00You each got a Bop It game.
0:25:00 > 0:25:02Basically a lot of prizes.
0:25:02 > 0:25:04A Blast Lab goodie bag, you all get those.
0:25:04 > 0:25:09Basically you've cleaned us out, Red Team. Congratulations, Red Team!
0:25:09 > 0:25:12CHEERING AND APPLAUSE
0:25:13 > 0:25:17Yellow Team, this is the difficult bit.
0:25:17 > 0:25:19Now we find out what you would have won.
0:25:19 > 0:25:22You would each have taken home an atomic telescope.
0:25:22 > 0:25:25You're not because instead you're going to blow it up.
0:25:25 > 0:25:27It's now time for Bidet Goes Bang!
0:25:35 > 0:25:38- Yellow Team, how are you feeling? - Great(!)
0:25:38 > 0:25:42This is rather rubbing it in because the Red Team's prizes
0:25:42 > 0:25:46are here in a huge pile and you're here without any.
0:25:46 > 0:25:50You have got some but they're in the bidet waiting to be exploded.
0:25:50 > 0:25:52- Who's going to push the plunger? - All of us.
0:25:52 > 0:25:54- All together?- Yep.
0:25:54 > 0:25:57The way of it, team, then you can't blame anybody afterwards.
0:25:57 > 0:26:00What went wrong?
0:26:00 > 0:26:05I couldn't get a grip when Anne-Marie gave it to me. I couldn't get it.
0:26:05 > 0:26:06It is very difficult.
0:26:06 > 0:26:11It's some consolation because when I created this next invention,
0:26:11 > 0:26:15it was a real pain in the bum, quite literally, because it is
0:26:15 > 0:26:18my exploding bidet. There is no putting this off.
0:26:18 > 0:26:22Your prizes are already in position. It's time to do it.
0:26:22 > 0:26:24Lift the plunger, please.
0:26:24 > 0:26:26Don't push it down, lift it up.
0:26:26 > 0:26:28Wait. Let's count you down.
0:26:28 > 0:26:33ALL: Five, four, three, two, one.
0:26:33 > 0:26:36EXPLOSION
0:26:43 > 0:26:47It's done, it's done. We've seen how by using the Bernoulli principal,
0:26:47 > 0:26:51you can make a beach ball fly and a car sail.
0:26:51 > 0:26:53We've learned a lot about Bernoulli's wind.
0:26:53 > 0:26:56Who sniggered? See you next time.
0:26:56 > 0:27:01CHEERING AND APPLAUSE
0:27:01 > 0:27:04Keep pedalling! Keep pedalling!
0:27:14 > 0:27:17Blast Lab was recorded before a live studio audience.
0:27:17 > 0:27:20No Lab Rat was harmed during the filming.
0:27:20 > 0:27:24Well, there was a minor injury but he's OK now...I think.
