0:00:36 > 0:00:40Hold on! A-ha! Yeah, try that.
0:00:41 > 0:00:43Yeah.
0:00:43 > 0:00:46Thank goodness I had my safety goggles with me.
0:00:46 > 0:00:50They ward off all danger. And that's why we always wear them in here.
0:00:50 > 0:00:52Hello, I'm Richard Hammond. Welcome to Blast Lab.
0:00:56 > 0:00:59This is where I do all my top secret science,
0:00:59 > 0:01:02experimenting with incredible machines that transport matter
0:01:02 > 0:01:05through time and space. And with mutant monsters
0:01:05 > 0:01:07that turn out to be able to escape from their cages.
0:01:07 > 0:01:11Today, I'm going to be putting two teams through their paces,
0:01:11 > 0:01:14to discover which group has the best scientific minds.
0:01:14 > 0:01:15Let's see what's in store.
0:01:27 > 0:01:30If you're going to do top-secret experiments
0:01:30 > 0:01:33in your lab, you can't have just anyone wandering in.
0:01:33 > 0:01:36That's why I have the best security available to protect this place -
0:01:36 > 0:01:40the SAS. Unfortunately, a lot of their mums have birthdays around
0:01:40 > 0:01:43now. So, they've all gone shopping together, for presents,
0:01:43 > 0:01:45instead of coming to work.
0:01:45 > 0:01:48Luckily for me, my Nan is a one-woman fighting machine.
0:01:48 > 0:01:50It is Ninja Nan.
0:01:50 > 0:01:52APPLAUSE AND CHEERING
0:01:58 > 0:02:03Didn't you see the huge monster? The huge teeth, the wings, the pincers?
0:02:03 > 0:02:06No? OK, I don't want to know what happened.
0:02:06 > 0:02:09But, thanks for standing in. I know, she may look fragile.
0:02:09 > 0:02:11But she is actually a trained ninja.
0:02:15 > 0:02:19See? Take your place in security now, please, Nan. Nan!
0:02:19 > 0:02:22Nan! If you'd like to take your place in security.
0:02:22 > 0:02:23Thank you very much, indeed.
0:02:23 > 0:02:25There she goes.
0:02:25 > 0:02:27Look at that, look at the speed.
0:02:27 > 0:02:31She is so fast she has to slow down to catch blue bottles.
0:02:31 > 0:02:33OK, Nan is settled in.
0:02:33 > 0:02:37It's time now to meet the people who are trying to get into my lab today.
0:02:37 > 0:02:39CHEERING AND APPLAUSE
0:02:41 > 0:02:43Don't clap yet, they could be anybody!
0:02:43 > 0:02:47We've got to be certain, before we let them through security.
0:02:47 > 0:02:48You say you're the Yellow Team?
0:02:48 > 0:02:51Identify yourselves by names, please.
0:02:51 > 0:02:54- Daryl!- Tom!- MJ!- Daryl, Tom, MJ. Yup, that checks out.
0:02:54 > 0:02:57Now, I'm going to ask you to perform a hidden talent,
0:02:57 > 0:03:00so we can be sure you're the right people to let in.
0:03:00 > 0:03:04Tom, it says here, you can do kick boxing. Don't move a muscle!
0:03:04 > 0:03:07Don't move. Right now, you're in incredible danger.
0:03:07 > 0:03:10Because Ninja Nan is there, poised behind you.
0:03:10 > 0:03:13If you even think about kick boxing, it'll get messy in there.
0:03:13 > 0:03:17Lab rats to security, make Ninja Nan safe. Thank you.
0:03:17 > 0:03:20There you go. See, that'll be fine, that'll be fine.
0:03:20 > 0:03:22Yes, that'll hold her in.
0:03:22 > 0:03:24Oh, double, just to be certain.
0:03:24 > 0:03:26Right, Tom, do your stuff. Prove it.
0:03:29 > 0:03:30Oh, crikey! Yup, yup.
0:03:30 > 0:03:33That's looking like kick boxing to me. Yup.
0:03:33 > 0:03:36You are cleared through security. You can come into the lab.
0:03:36 > 0:03:38APPLAUSE
0:03:42 > 0:03:45Hello, Yellow Team. Welcome to Blast Lab. Where you from?
0:03:45 > 0:03:51ALL: We're from Oxfordshire, and we're the Speedy Brains!
0:03:51 > 0:03:53No, you're the Yellow Team.
0:03:53 > 0:03:56But welcome to Blast Lab. Thanks for coming in. Good luck.
0:03:56 > 0:03:59Let's meet the people you're going to be playing against.
0:03:59 > 0:04:01APPLAUSE AND CHEERING
0:04:02 > 0:04:05Hold on, hold on! They say they're the Red Team.
0:04:05 > 0:04:08Can't be too sure, can't let just anybody in here.
0:04:08 > 0:04:11For security reasons. So, identify yourselves by names, please.
0:04:11 > 0:04:15- Harriet!- Portia!- Lucy! - Harriet, Portia, Lucy.
0:04:15 > 0:04:17Yup, that's right.
0:04:17 > 0:04:20Under hidden talent on the security form, it says, Portia,
0:04:20 > 0:04:22you can scream really loud.
0:04:22 > 0:04:24- Yeah.- Well, go on then.
0:04:24 > 0:04:26AHHHHHH!
0:04:26 > 0:04:28Yup, OK, that, that was really loud!
0:04:28 > 0:04:31You are the Red Team. Come through security, past Ninja Nan.
0:04:31 > 0:04:33APPLAUSE AND CHEERING
0:04:35 > 0:04:38Hello, Red Team. Welcome to Blast Lab.
0:04:38 > 0:04:44- Where are you lot from?- ALL: Leicester! We're the Tireless Trio.
0:04:44 > 0:04:47You're not! You're the Red Team! But, welcome to Blast Lab.
0:04:47 > 0:04:50Thanks for coming. Good luck. It's time for round one.
0:04:50 > 0:04:52So, teams, take your positions.
0:04:52 > 0:04:54Go and get settled in, Red and Yellow teams.
0:04:54 > 0:04:58Right, some cars can do 0 to 60 in two seconds.
0:04:58 > 0:05:01Some cars can beat Einstein in a quiz. I have the latter.
0:05:01 > 0:05:04He is the cleverest thing on four wheels. It's Oliver.
0:05:23 > 0:05:27Oliver spends his time off roaming the globe to collect facts
0:05:27 > 0:05:29for his high-tech fact nav.
0:05:29 > 0:05:33I built it - so it doesn't always work. Some of the facts are true.
0:05:33 > 0:05:35Some of the facts are false.
0:05:35 > 0:05:37Fortunately, Oliver knows which is which.
0:05:37 > 0:05:40So, I'm going to give each team a science fact.
0:05:40 > 0:05:43They're going to tell me if they think it's right or wrong.
0:05:43 > 0:05:45If it is true, Oliver will do this.
0:05:45 > 0:05:47TOOTING AND HONKING
0:05:48 > 0:05:52And, if it's false, Oliver will let us know, like this.
0:05:52 > 0:05:54FOG HORN BLASTS
0:05:54 > 0:05:57Simple enough. OK, teams, this is it.
0:05:57 > 0:06:00Your first chance to earn points in Blast Lab.
0:06:00 > 0:06:02OK, Reds, you're going first.
0:06:02 > 0:06:05Here is your fact. You have to tell me whether this is true or false.
0:06:05 > 0:06:09Sea water is heavier than fresh water.
0:06:09 > 0:06:13Is it heavier than fresh water? Have a think. Audience, what do we think?
0:06:13 > 0:06:15True!
0:06:15 > 0:06:17A few false in there.
0:06:17 > 0:06:20- Mostly true. What do we think? - I think it's true.
0:06:20 > 0:06:23OK. True is the team's answer?
0:06:23 > 0:06:25Oliver, is it true or false?
0:06:25 > 0:06:27TOOTING AND HONKING
0:06:29 > 0:06:31It's actually loaded with minerals,
0:06:31 > 0:06:35so it weighs 24 kilograms more, per cubic metre, than fresh water.
0:06:35 > 0:06:38Well done. That's the first point to you, Reds. OK, Yellows.
0:06:38 > 0:06:41This is your chance to equalise.
0:06:41 > 0:06:44The red colour of Mars
0:06:44 > 0:06:47is created by rust. Is that true or false?
0:06:47 > 0:06:49Have a think, have a think.
0:06:49 > 0:06:52Audience, what do we think, is that true of false?
0:06:52 > 0:06:55- True!- False!
0:06:55 > 0:06:58Look at that, it's split the audience down the middle, I reckon.
0:06:58 > 0:07:01Half, half. Have you had enough time to think about that one?
0:07:01 > 0:07:03Your first chance to earn points.
0:07:03 > 0:07:06Tom, MJ, Daryl. I don't like to make you nervous.
0:07:06 > 0:07:09It's your first chance to equalise. What do we think?
0:07:09 > 0:07:12- True.- You think that's true. Oliver, is it true or false?
0:07:12 > 0:07:14TOOTING AND HONKING
0:07:14 > 0:07:15It's true, well done!
0:07:15 > 0:07:18That's the equalising point. They're on one a piece.
0:07:18 > 0:07:21The reddy-orange colour of the surface of Mars is
0:07:21 > 0:07:24caused by iron oxide, made by the reaction of iron with oxygen.
0:07:24 > 0:07:26So it's just like when your car rusts.
0:07:26 > 0:07:28Not that Oliver knows about that.
0:07:28 > 0:07:32Because he wouldn't do anything like that. No. Right, your last question.
0:07:32 > 0:07:34This one is a bit different.
0:07:34 > 0:07:37This isn't a true or false question. I'm going to give you
0:07:37 > 0:07:39an actual question. You've got to give me an answer.
0:07:39 > 0:07:42Write it down on those pads in front of you. It's not that easy.
0:07:42 > 0:07:45So, I'm going to give the point
0:07:45 > 0:07:48to the team that's nearest to the correct answer.
0:07:48 > 0:07:54And here comes the question. How tall was the tallest-ever iceberg?
0:07:54 > 0:07:57What I want is the measurement, above the water line.
0:07:57 > 0:07:59Let's go for metres, I think.
0:07:59 > 0:08:02If you both turn round your boards now, so we can all have a look.
0:08:02 > 0:08:05Reds, 75 metres.
0:08:05 > 0:08:07Yellows, 1,500 metres.
0:08:07 > 0:08:09Quite a range there - quite a difference.
0:08:09 > 0:08:12Well, the actual answer is 168 metres tall.
0:08:12 > 0:08:17Which means that the Red Team are the winners. Well done, Reds!
0:08:17 > 0:08:18APPLAUSE AND CHEERING
0:08:18 > 0:08:20It was the Melville Bay iceberg,
0:08:20 > 0:08:23sighted off the coast of Greenland in 1958.
0:08:23 > 0:08:26Otherwise you'd have noticed it, I'm sure.
0:08:26 > 0:08:30At that height, it's as tall as 112 Ninja Nans, if you were wondering.
0:08:30 > 0:08:31And wanted to measure it properly.
0:08:31 > 0:08:34So, the points now are two to the Reds, one to the Yellows!
0:08:46 > 0:08:49That is all to come. But first, it is mini science -
0:08:49 > 0:08:53the round where our teams perform complex scientific experiments,
0:08:53 > 0:08:55using simple household objects.
0:08:55 > 0:08:58And, for this round, I need to break out the really big science guns.
0:08:58 > 0:09:00Well, actually, quite a small one.
0:09:00 > 0:09:03But she is the real science deal. It is Mini Miss!
0:09:05 > 0:09:09- Hello, Richard.- Hello. Yes, slight mix up with the time machine.
0:09:09 > 0:09:11So, my school science teacher is here in Blast Lab.
0:09:11 > 0:09:14She just happens to be... ten years old.
0:09:14 > 0:09:17- Yes, thanks for that, Richard.- Sorry.
0:09:17 > 0:09:19So, what are we doing today, Miss?
0:09:19 > 0:09:23Well, today's teams are going to be launching their very own rockets,
0:09:23 > 0:09:27using straws, bottles and a foot pump.
0:09:27 > 0:09:29They have six bottles to choose from.
0:09:29 > 0:09:33Oh. So they all choose from these bottles. Once they've chosen
0:09:33 > 0:09:35a bottle, how do they turn that into a rocket?
0:09:35 > 0:09:38First, they have to attach it to their launch wire,
0:09:38 > 0:09:41using a straw and some Velcro.
0:09:41 > 0:09:45Then, once it's attached, they have to pump air
0:09:45 > 0:09:47into the bottle, using a foot pump.
0:09:47 > 0:09:51Eventually, the air should become so much inside the bottle,
0:09:51 > 0:09:53that it forces the pump out.
0:09:53 > 0:09:56- Oh, so, it turns into a rocket at that point.- Yes.
0:09:56 > 0:09:58- That's clever. - Teams take it in turns to choose
0:09:58 > 0:09:59and launch their rockets.
0:09:59 > 0:10:02The team with the most points wins the game.
0:10:02 > 0:10:05Fair enough. Red Team, you are in the lead at the moment,
0:10:05 > 0:10:09so you get to go first in this. Launching a bottle rocket isn't that
0:10:09 > 0:10:12easy. It's rocket science, after all. Mini Miss is going to take
0:10:12 > 0:10:16you over to the launch pad and talk you through the process.
0:10:16 > 0:10:19So if you'd all like to go over there with Mini Miss.
0:10:19 > 0:10:22She's going to explain how to launch your bottle rockets.
0:10:22 > 0:10:25See, the thing is, with these bottle rockets,
0:10:25 > 0:10:28yes, we're using air pressure, to fire them up the wire.
0:10:28 > 0:10:31But there's something else more important in action here,
0:10:31 > 0:10:36something that was explained by one of Blast Lab's all-time heroes.
0:10:36 > 0:10:38He really was the business.
0:10:38 > 0:10:40Sir Isaac Newton.
0:10:42 > 0:10:47A fabulously clever bloke, who did some very clever scientific stuff.
0:10:47 > 0:10:50But he was probably best at explaining complicated things
0:10:50 > 0:10:53so that we could all understand them. He came up with some laws,
0:10:53 > 0:10:56about stuff that's going on around us all the time.
0:10:56 > 0:11:01And his law number three explained how space rockets work.
0:11:01 > 0:11:05Well, not directly, because space rockets hadn't been invented.
0:11:05 > 0:11:09But it explained the principles that still happen today.
0:11:09 > 0:11:12Basically, in every rocket, when it fires its engine to get up
0:11:12 > 0:11:16into space, it pushes that way. And that means there's a push that way.
0:11:16 > 0:11:18That was Newton's law, you see?
0:11:18 > 0:11:21He said, for every shove that way, there's a shove that way.
0:11:21 > 0:11:24For every action, there's an equal and opposite reaction.
0:11:24 > 0:11:27So, as the rocket shoves that way, it goes that way.
0:11:27 > 0:11:29And it's the same here.
0:11:29 > 0:11:32As the air forces itself out that way, it pushes that way.
0:11:32 > 0:11:34And that means the rocket goes that way.
0:11:34 > 0:11:36Look at her, standing around.
0:11:36 > 0:11:40Talking about Sir Isaac Newton's Third Law. What?
0:11:41 > 0:11:43I've gone on a bit, haven't I?
0:11:43 > 0:11:47You're ready to go, aren't you? Right, let's get on with this, then.
0:11:47 > 0:11:50Reds, get into position there. Choose your rocket, please.
0:11:50 > 0:11:52Yellows, go behind the table and await your turn.
0:11:55 > 0:11:58- Reds, have you decided on your rocket?- Yeah.
0:11:58 > 0:12:00- Which one is it?- That one.- Why?
0:12:00 > 0:12:03Because it's very streamline.
0:12:03 > 0:12:06Good, thinking about the aerodynamics of the thing?
0:12:06 > 0:12:09Very good. OK, well, step up to the launch pad with your rocket.
0:12:17 > 0:12:21Right, it's coming up to pressure now. Here we go.
0:12:22 > 0:12:25Yeah! Oh... Well, you know, it's not space.
0:12:25 > 0:12:28But it launched, it launched.
0:12:28 > 0:12:30Personally, I'm...
0:12:30 > 0:12:31APPLAUSE
0:12:31 > 0:12:34Sadly, that doesn't score you any points at all.
0:12:34 > 0:12:36It's not quite in the zone for one point.
0:12:39 > 0:12:42Yellow team, choose your bottle, step up to the mark.
0:12:42 > 0:12:44And do your launch.
0:12:48 > 0:12:50Away we go. If is this is a bigger bottle,
0:12:50 > 0:12:53it's going to take more air, isn't it?
0:12:56 > 0:13:00Anybody got much to do, this evening? Busy tomorrow?
0:13:03 > 0:13:07Wahey! Look at that! Wow.
0:13:09 > 0:13:10Well, done, Yellows.
0:13:10 > 0:13:13So, that's five points. Now, here's how it's going to work.
0:13:13 > 0:13:17At the end of this, whoever's got the most points off there, will win
0:13:17 > 0:13:19this game and win a point, overall. OK?
0:13:23 > 0:13:26- Reds, which bottle for your next attempt?- That one.
0:13:26 > 0:13:27The big one. Because?
0:13:27 > 0:13:31- It carries far.- Frankly, because you just saw it work really well
0:13:31 > 0:13:34and a scientist learning from experiments is what it's all about.
0:13:37 > 0:13:40Lab rat, is that seal correct?
0:13:40 > 0:13:41Get off there.
0:13:44 > 0:13:47Here we go. OK, we're walking up towards a launch.
0:13:49 > 0:13:52Keep pumping! Air's being squashed in,
0:13:52 > 0:13:54when it wants to escape...
0:13:54 > 0:13:56that's what will make this work.
0:13:56 > 0:13:58We're all getting tired of going "whoa-a-a!"
0:14:01 > 0:14:05Yes! Whoa, is that in the five zone?
0:14:05 > 0:14:07Yes, it is. It's in the five zone.
0:14:07 > 0:14:12Well, done. Good effort, Reds. Well done, well done.
0:14:14 > 0:14:17- Right, Yellows, which rocket you going for now?- That one.
0:14:17 > 0:14:20Oh, this one you can't use. This is Mini Miss's special one.
0:14:20 > 0:14:22She'll get very angry.
0:14:22 > 0:14:25Miss, they nearly took your own special rocket there. Which one?
0:14:25 > 0:14:27- That one.- Why? - Because it's streamline,
0:14:27 > 0:14:30- like the other one was.- So, you're thinking streamline?
0:14:30 > 0:14:32OK, good luck, good luck.
0:14:32 > 0:14:34All the time that air being pumped into the bottle,
0:14:34 > 0:14:37squashed up to the end. Because you can compress it.
0:14:37 > 0:14:40Oh! Oh, not bad.
0:14:40 > 0:14:41APPLAUSE
0:14:41 > 0:14:44I think that's in the two zone. It didn't quite make it to three.
0:14:44 > 0:14:45Still, well done.
0:14:48 > 0:14:51OK, Reds, you're going with that one because...?
0:14:51 > 0:14:54- It is fat.- We just... - Hang on. This is a different issue.
0:14:54 > 0:14:57Because you guys were talking about streamline.
0:14:57 > 0:15:00This time you're talking about it's got more air in it.
0:15:00 > 0:15:02That's why you want it. OK.
0:15:04 > 0:15:09OK, Reds, you, at the moment, have a total of five points.
0:15:09 > 0:15:10The Yellows have seven points.
0:15:10 > 0:15:12So, unless you get three...
0:15:12 > 0:15:14which will take you to eight overall on this...
0:15:14 > 0:15:17you'll have lost. Keep going, keep pumping.
0:15:17 > 0:15:21You can hear it's about to launch...
0:15:21 > 0:15:24Yes! Whoa, well done!
0:15:26 > 0:15:28Well done.
0:15:28 > 0:15:30Reds on a total of nine.
0:15:31 > 0:15:34So, Yellows are on a total of seven.
0:15:34 > 0:15:37You need to get three or more with this to win.
0:15:49 > 0:15:53Here we go. You can hear a bit of air escaping.
0:15:53 > 0:15:58Ah, Yellows, I'm so sorry. That means then, the Reds win that game.
0:15:58 > 0:16:01You win the point for the Reds. Well done!
0:16:01 > 0:16:03APPLAUSE
0:16:03 > 0:16:05Total scores, three, one.
0:16:05 > 0:16:07So, our bottle rockets there, using just air,
0:16:07 > 0:16:11and, of course, old Isaac Newton's Third Law. He really was brilliant.
0:16:11 > 0:16:13Sorry, I'm a fan. I can't help it!
0:16:13 > 0:16:16They're pretty effective, but we can make them more powerful
0:16:16 > 0:16:19by changing the mixture of our rocket fuel.
0:16:19 > 0:16:21And we don't have to add anything that explodes.
0:16:21 > 0:16:25Just simple water will do.
0:16:25 > 0:16:28This is a water rocket scientist.
0:16:28 > 0:16:30Hello, I'm a water rocket scientist.
0:16:31 > 0:16:35He claims that his rudimentary water rockets, made out of nothing more
0:16:35 > 0:16:39than plastic bottles, sticky tape and an old bin bag...
0:16:39 > 0:16:43can fly higher than a firework. Or even a distress flare.
0:16:44 > 0:16:48In a brave attempt to teach my lab rats something useful,
0:16:48 > 0:16:52he's going to show them how he builds his rockets.
0:16:52 > 0:16:54They work using
0:16:54 > 0:16:58a combination of high pressure and Newton's Third Law of Motion.
0:16:58 > 0:17:01Our scientist part fills the rocket with water
0:17:01 > 0:17:06and increases the pressure inside, until it's ready to burst.
0:17:06 > 0:17:08Then, we simply release the pressure,
0:17:08 > 0:17:12which allows the water to escape downwards with incredible force.
0:17:16 > 0:17:21And this pushes the bottle rocket upwards and into the sky.
0:17:21 > 0:17:25Meanwhile, my highly-focused lab rats are paying our expert as much
0:17:25 > 0:17:28attention as they did to their teachers at school.
0:17:28 > 0:17:31Right, enough of that.
0:17:31 > 0:17:33It's time for a test.
0:17:34 > 0:17:39Don't worry about the danger our lab rat assistants might be in here.
0:17:39 > 0:17:43They're completely useless and bred for this type of thing.
0:17:43 > 0:17:45And only they'd be stupid enough to get involved
0:17:45 > 0:17:47with this sort of experiment.
0:17:49 > 0:17:51Three...
0:17:51 > 0:17:53Two...
0:17:53 > 0:17:55One...
0:17:55 > 0:17:57Blast off!
0:18:02 > 0:18:04The firework was a slow starter.
0:18:04 > 0:18:06But it's soon overtaken the water rocket.
0:18:11 > 0:18:13The firework wins.
0:18:13 > 0:18:17So, his small water rocket failed to beat the firework.
0:18:17 > 0:18:19But how will our expert's biggest rocket
0:18:19 > 0:18:22get on against this distress flare?
0:18:22 > 0:18:24OK, let's hold that experiment right there.
0:18:24 > 0:18:26There's an extra point in this...
0:18:26 > 0:18:30The score right now, 3-1, possible extra point for you, Yellows.
0:18:30 > 0:18:34..to the team that can tell me, will that big water rocket
0:18:34 > 0:18:39- go higher than the distress flare? Reds, does it do it, or not?- Yes.
0:18:39 > 0:18:42- You think it does. Yellows? - Yes.- You think it does.
0:18:42 > 0:18:45The two points cancel each other out if you get it right.
0:18:45 > 0:18:48There's only one way to find out - let's have a look at the experiment.
0:18:48 > 0:18:53Our water rocket scientist is just making his final preparations
0:18:53 > 0:18:55to his giant rocket.
0:18:55 > 0:18:57Oh, it's gone off too early!
0:18:57 > 0:19:00No, it looks like it's actually exploded.
0:19:01 > 0:19:03The top of the rocket blew off.
0:19:03 > 0:19:06But the bottom has been left behind.
0:19:06 > 0:19:08Right then, Mr Scientist,
0:19:08 > 0:19:11you've got one more chance with your back-up rocket.
0:19:11 > 0:19:15Just get your preparations right this time.
0:19:15 > 0:19:18Brilliant... The landing parachute's fallen off!
0:19:18 > 0:19:22You've got one more chance, rocket boffin. Let's go.
0:19:23 > 0:19:28OK, it hasn't gone off in his face, and the top hasn't fallen off.
0:19:28 > 0:19:29Here we go.
0:19:29 > 0:19:31Three...
0:19:31 > 0:19:32Two...one...
0:19:32 > 0:19:34Blast off!
0:19:36 > 0:19:38The rocket's not going off...
0:19:38 > 0:19:40The rocket is not going off!
0:19:40 > 0:19:43The flare's gone about a kilometre up into the sky.
0:19:43 > 0:19:46What's happening with the rocket?
0:19:46 > 0:19:47Ah!
0:19:49 > 0:19:50Watch out, lab rat!
0:19:51 > 0:19:53Oh, just missed.
0:19:53 > 0:19:55Well, thanks a lot, pal(!)
0:19:55 > 0:19:59Your status as water rocket scientist has just been revoked.
0:19:59 > 0:20:01Cheerio.
0:20:01 > 0:20:04Sorry, guys, no points.
0:20:04 > 0:20:06They didn't get points either. No points.
0:20:06 > 0:20:09Right, time now, then, for you all to go off
0:20:09 > 0:20:11and get ready for The Messy Messy Mess Test.
0:20:11 > 0:20:15Go and get your outfits on. You need your protective clothing.
0:20:15 > 0:20:16Trust me, you do need...
0:20:16 > 0:20:18Ohhh, that's bad!
0:20:18 > 0:20:21The water wheel's stopped outside. Means we've lost power.
0:20:21 > 0:20:24Never mind, I've made contingency plans!
0:20:24 > 0:20:27It's time to switch to emergency power. Lab rat!
0:20:27 > 0:20:29Get on that foot pump, please.
0:20:29 > 0:20:31Go on, on the foot pump! Charge it up.
0:20:31 > 0:20:35There you go. It's brilliant, this. I made it myself. Look at that.
0:20:35 > 0:20:37Probably every home should have one.
0:20:37 > 0:20:40It's perfectly green. But it'd take too long to explain.
0:20:40 > 0:20:42You carry on with that, thank you,
0:20:42 > 0:20:44while we move on to The Messy Messy Mess Test...
0:20:48 > 0:20:52..which today is in the septic tank.
0:20:52 > 0:20:55This is where all the waste from my different experiments goes.
0:20:55 > 0:20:59Actually, I managed to create a new type of tiny bacteria,
0:20:59 > 0:21:02the other day, that will eat away all the bad things in here,
0:21:02 > 0:21:05and convert it into pure water. It's brilliant.
0:21:05 > 0:21:08Unfortunately, one of the chemicals I threw away in here
0:21:08 > 0:21:11made some of the tiny bacteria mutate,
0:21:11 > 0:21:14to about the size of a medium rat.
0:21:14 > 0:21:17So, you might want to look out for those, in there...
0:21:17 > 0:21:20Here is the game, then. Hidden in this tank are discs.
0:21:20 > 0:21:22Some, like this, are duds.
0:21:22 > 0:21:26But the ones you're after are like these, held by my lab rat.
0:21:26 > 0:21:30They feature your team's colour, and the name of prizes.
0:21:30 > 0:21:36Things like MP3 players, a Bopit, maybe a radio-controlled mosquito.
0:21:36 > 0:21:38Lab rat, hide those, and get out.
0:21:38 > 0:21:42Thank you. Your job, teams, is to get as many prize discs as you can,
0:21:42 > 0:21:45with your team's colour, out of there and into these baskets.
0:21:45 > 0:21:48We have one for yellow and one for red.
0:21:48 > 0:21:51The team to get the most prize discs into their baskets
0:21:51 > 0:21:53will take home the prizes written on them.
0:21:53 > 0:21:57The losing team has to blow their prizes up.
0:21:57 > 0:21:59There's one further complication this week.
0:21:59 > 0:22:02Harriet, show us your arm.
0:22:02 > 0:22:04You've bust it.
0:22:04 > 0:22:06Clearly, with a broken arm,
0:22:06 > 0:22:09messing about in the septic tank is out of the question.
0:22:09 > 0:22:12Fortunately Harriet's brother, George, has volunteered
0:22:12 > 0:22:17to stand in and do it for her! Which I think is a pretty noble gesture.
0:22:17 > 0:22:20You didn't break this just to get out of going in there, did you?
0:22:20 > 0:22:22- No.- No. You did that weeks ago.- Yes.
0:22:22 > 0:22:24I think that's a pretty decent excuse.
0:22:24 > 0:22:27Red Team, you start first because you've got the most points,
0:22:27 > 0:22:31and they've earned you a five-second advantage.
0:22:31 > 0:22:35When you hear the first siren, start looking for prize discs.
0:22:35 > 0:22:39But Yellow Team, you listen out. As soon as you hear the second siren,
0:22:39 > 0:22:40you can start.
0:22:40 > 0:22:43You have some time to get as many prize discs as you can
0:22:43 > 0:22:44into these baskets.
0:22:44 > 0:22:46And that some time starts...
0:22:46 > 0:22:47NOW!
0:22:47 > 0:22:49SIREN WAILS
0:22:49 > 0:22:51Into the septic gunge dive the Reds.
0:22:51 > 0:22:55Without a single thought for their own safety. Or personal hygiene.
0:22:55 > 0:22:57- SIREN WAILS - The second siren...
0:22:57 > 0:22:59and the Yellows immediately getting stuck in.
0:22:59 > 0:23:03Quite literally, getting stuck in...
0:23:03 > 0:23:06The Yellows already finding prize discs.
0:23:06 > 0:23:08Come on, Reds. He might be losing his hat,
0:23:08 > 0:23:12but that is another prize disc already, for the Yellows!
0:23:12 > 0:23:13What's going on, Reds?
0:23:13 > 0:23:18Their basket is empty, while the Yellows' is bulging already.
0:23:18 > 0:23:21The Reds seem to have a knack for finding all of the fake discs.
0:23:21 > 0:23:23A commendable achievement,
0:23:23 > 0:23:27but one that will earn them exactly no prizes!
0:23:27 > 0:23:32Oh, and another white disc in the red basket. Brilliant.
0:23:33 > 0:23:36It's amazing. Every time I forget to warn them that,
0:23:36 > 0:23:38sometimes, the pipes will spew out
0:23:38 > 0:23:42more of the hideous, nameless goo into the tank.
0:23:42 > 0:23:46But they do bring prize discs with them, sometimes.
0:23:46 > 0:23:47So, there's a positive side.
0:23:53 > 0:23:56Looks like Reds are getting their act together.
0:23:56 > 0:23:57But do they have enough time?
0:23:57 > 0:24:00Who knows, with my "some time" clock!
0:24:06 > 0:24:08GIRL SHRIEKS
0:24:08 > 0:24:10Oh, a huge septic gunk shower there,
0:24:10 > 0:24:12for an unfortunate member of the Red Team.
0:24:12 > 0:24:15I think that shriek said it all.
0:24:15 > 0:24:17The Reds then, in a complete mess,
0:24:17 > 0:24:21while the Yellows methodically go about their business.
0:24:21 > 0:24:25But with both baskets looking pretty healthy now, it's anyone's guess
0:24:25 > 0:24:28who will emerge from the gunge, to the sweet smell of victory.
0:24:28 > 0:24:30And who will just...smell.
0:24:34 > 0:24:35END-OF-GAME BUZZER
0:24:35 > 0:24:39Time is up, time is up.
0:24:39 > 0:24:40You're all still with us.
0:24:40 > 0:24:43George, thank you for standing in there. Well done.
0:24:43 > 0:24:45Let's see which team has won.
0:24:45 > 0:24:48How many then for the Reds, lab rat?
0:24:48 > 0:24:51Seven for the Reds! Well done. Well done.
0:24:51 > 0:24:52APPLAUSE
0:24:52 > 0:24:55But let's find out if that's enough to clinch it.
0:24:55 > 0:24:56Lab rat, how many for the Yellows?
0:24:56 > 0:25:02Nine? Nine for the Yellows? That's amazing.
0:25:02 > 0:25:06Yellows, that's incredible. You're each going to take home with you...
0:25:06 > 0:25:09a crystal growing kit...
0:25:09 > 0:25:11plug and play electronic kit...
0:25:11 > 0:25:13white wings glider kit...
0:25:13 > 0:25:16remote control mosquito...
0:25:16 > 0:25:18cosmic flashing scooter...
0:25:18 > 0:25:21a chemistry set...
0:25:21 > 0:25:24Robo Bugs...
0:25:24 > 0:25:26kitchen chemistry set...
0:25:26 > 0:25:28a microscope.
0:25:28 > 0:25:30- Is this part of it?- Yes-s-s... - No, it's not.- Yes, it is.
0:25:30 > 0:25:34That didn't get in there. Sorry, lads, the disc wasn't in.
0:25:34 > 0:25:36Is this the time to appear ungrateful, Tom? Let's think.
0:25:36 > 0:25:39You're taking home one of those each.
0:25:39 > 0:25:42Whereas the Red Team have a rather different fate awaiting them.
0:25:42 > 0:25:46Because all of these prize discs are what you would have won.
0:25:46 > 0:25:48- Cosmic flashing scooter...- Ohh.
0:25:48 > 0:25:51..Bopit. That would have been nice.
0:25:51 > 0:25:54White wings glider kit, that would have been handy. Yeah.
0:25:54 > 0:25:57Robo Bugs, nice.
0:25:57 > 0:26:00A microscope...oh, yeah.
0:26:00 > 0:26:03An MP3 player each. That would have been nice.
0:26:03 > 0:26:05And chemistry set. You would've won one.
0:26:05 > 0:26:07But, instead of taking them home,
0:26:07 > 0:26:10you're going to blow them up. It's Bidet Goes Bang!
0:26:18 > 0:26:21It's that time, in the Blast Lab, once again.
0:26:21 > 0:26:23When, strangely, one team,
0:26:23 > 0:26:27the team standing behind a massive pile of prizes, looks really happy.
0:26:27 > 0:26:29Yellows, well done. You won.
0:26:29 > 0:26:31All of that lot going home with you.
0:26:31 > 0:26:33The other team, today the Reds,
0:26:33 > 0:26:37not...quite...so happy. How you feeling?
0:26:37 > 0:26:40- Sad.- Yeah, well, you know, somebody had to win.
0:26:40 > 0:26:44Somebody had to lose. That's how it goes. Like Newton's Third Law -
0:26:44 > 0:26:47There's an equal... I won't go on about it again, right now.
0:26:47 > 0:26:49What do you think went wrong?
0:26:49 > 0:26:52- BOTH: We weren't quick enough. - It's really difficult in there.
0:26:52 > 0:26:56Bad luck, Reds. Who's going to push the plunger, and do the dirty deed?
0:26:56 > 0:26:59- All of us.- I think that's probably the best way to do it.
0:26:59 > 0:27:01Right, the moment is nearly upon us.
0:27:01 > 0:27:04In this very lab, I've tried exploding things in kettles,
0:27:04 > 0:27:07exploding things in vases. But, if there's one thing I've learnt,
0:27:07 > 0:27:10it's that you always get the best bang from a bidet.
0:27:10 > 0:27:13And here it is, with your prizes in.
0:27:13 > 0:27:15Reds, if you'd like to step forward, please.
0:27:15 > 0:27:17Make ready with the plunger. Lift it up...
0:27:17 > 0:27:20We'll all give you the countdown. All ready, audience?
0:27:20 > 0:27:25Five, four, three, two, one!
0:27:29 > 0:27:33Yup, there you go, there you go. Bad luck, Reds. Well done, Yellows.
0:27:33 > 0:27:36Today we've learned about Newton's Third Law -
0:27:36 > 0:27:38every action has an equal and opposite reaction.
0:27:38 > 0:27:42And that not all rockets go quite to plan. See you next time.
0:27:42 > 0:27:43APPLAUSE
0:27:43 > 0:27:46Sorry, Reds. Well done, Yellows.
0:27:50 > 0:27:54Blast Lab was recorded in front of a live studio audience.
0:27:54 > 0:27:57No lab rats were hurt during filming... Probably.
0:27:57 > 0:27:59Wouldn't have felt it if they were.
