0:00:33 > 0:00:34APPLAUSE AND CHEERING
0:00:34 > 0:00:38And finally, you'll need to wear these super dark goggles
0:00:38 > 0:00:42to protect your eyes if you're studying sun spots, OK?
0:00:42 > 0:00:47Yes, nothing can get in. No, don't try them on now! Yep(!)
0:00:47 > 0:00:51Hello, I'm Richard Hammond, this is my Blast Lab!
0:00:51 > 0:00:53APPLAUSE AND CHEERING
0:00:53 > 0:00:56This is the place where all my wildest dreams,
0:00:56 > 0:00:59and my lab rats' worst nightmares, become a reality.
0:00:59 > 0:01:03Today's visitors are two teams of young scientists who are competing
0:01:03 > 0:01:07in a series of scientific challenges to win a host of exciting prizes
0:01:07 > 0:01:09and hopefully, make all their dreams,
0:01:09 > 0:01:11and not too many of their nightmares, come true.
0:01:11 > 0:01:14Coming up today, we have Fact Nav 2.0
0:01:14 > 0:01:16with my intellectually-advanced friend Oliver.
0:01:21 > 0:01:24In Mini Science, our teams will have a go at surfing
0:01:24 > 0:01:28and trying to get some big air on... Well, on air.
0:01:31 > 0:01:35Meanwhile, the lab rats are trying to use something lighter
0:01:35 > 0:01:37than the air in their heads...
0:01:37 > 0:01:40Helium.
0:01:42 > 0:01:46And we return to the bacterial breeding ground of the septic tank
0:01:46 > 0:01:50to take on the virus that's plaguing the Snot Bots.
0:01:53 > 0:01:56Now, to keep the bad guys out of my lab,
0:01:56 > 0:01:58I have the very best in security systems...
0:01:58 > 0:02:01my Ninja Nan.
0:02:07 > 0:02:10There she is... Can you see what she doing?
0:02:10 > 0:02:13Oh, she's playing knock-out whist with the lab rats.
0:02:15 > 0:02:18She never did understand the rules of that game.
0:02:18 > 0:02:21Let's look at who's trying to get into my lab today.
0:02:25 > 0:02:28Hello, hello. Well, welcome to the Nannex.
0:02:28 > 0:02:32- You three claim to be the Red Team, yes?- Yes.
0:02:32 > 0:02:35For security reasons, identify yourselves by name. You are?
0:02:35 > 0:02:38- Saxon!- Cormack!- Archie!
0:02:38 > 0:02:41Saxon, Cormack, Archie. Yes, that checks out.
0:02:41 > 0:02:45- Under "Talent", what will you do for us?- ALL: Football!
0:02:45 > 0:02:48This is to prove who you are. Football? Carry on then.
0:02:48 > 0:02:51Oh, fair enough. Oh, right.
0:02:51 > 0:02:55Fair enough, that was football, you're clear, come through.
0:02:58 > 0:03:02Welcome to the lab, guys. You're only through this far.
0:03:02 > 0:03:04You're not actually all the way through yet,
0:03:04 > 0:03:08because just to be absolutely sure you are who you say you are,
0:03:08 > 0:03:11for security reasons, we agreed on a password with the real Red Team.
0:03:11 > 0:03:14If you're the real Red Team, you'd know the password.
0:03:14 > 0:03:17It would be what's written down. What do you think it is?
0:03:17 > 0:03:19ALL: Handstand Hooverers.
0:03:19 > 0:03:23And it is! Can I ask, why? What on earth does that mean?
0:03:23 > 0:03:27Because we don't like gymnastics and we don't like cleaning.
0:03:27 > 0:03:30- What, so all three of you don't? - Yes.- OK.
0:03:30 > 0:03:32Get ready for the first round. They are your Red Team.
0:03:32 > 0:03:35It's official. They're through security.
0:03:35 > 0:03:38Let's look at the people claiming to be the Yellow Team.
0:03:43 > 0:03:46Hello. You three say you're the Yellow Team, yes?
0:03:46 > 0:03:50Well, identify yourselves by name for security reasons. You are?
0:03:50 > 0:03:52- Joshua.- Chloe.- Natasha.
0:03:52 > 0:03:55Joshua, Chloe, Natasha. Fair enough, that checks out.
0:03:55 > 0:03:57Under 'hidden talent', Joshua, I've got your name.
0:03:57 > 0:04:01- What are you doing for us? - My impression of an Egyptian chicken.
0:04:01 > 0:04:04Yes, you see, that's what it said on the security form here.
0:04:04 > 0:04:08I thought they'd written it down wrong. Well, take it away.
0:04:09 > 0:04:12I've never seen anything like that.
0:04:12 > 0:04:15You could have got away with claiming that was boxing!
0:04:15 > 0:04:19That was an Egyptian chicken as none of us know otherwise.
0:04:19 > 0:04:22You're clear, come through to the lab.
0:04:24 > 0:04:28That's quite staggering, Joshua. Do you do any other impressions?
0:04:28 > 0:04:30Don't, please, but good luck.
0:04:30 > 0:04:33If you are the real Yellow Team, you'll know the password
0:04:33 > 0:04:37that we agreed with the real Yellow Team. What is it?
0:04:37 > 0:04:39- ALL: Sweets. - Yes, it is!
0:04:39 > 0:04:42Why? Because you all like sweets?
0:04:42 > 0:04:45- I hate sweets.- What?- I hate sweets.
0:04:45 > 0:04:50- She just said she hates sweets. What?- I hate sweets.
0:04:50 > 0:04:54See, I'm sorry, I thought you said, Natasha, "I hate sweets".
0:04:54 > 0:04:57You did say that. OK, get ready for the first round.
0:04:57 > 0:05:00They are your Yellow Team.
0:05:00 > 0:05:02It's official, we've got the teams.
0:05:02 > 0:05:05It's time for a car that can't pass its MOT but has a boot full of PhDs.
0:05:05 > 0:05:06It is, of course, Oliver.
0:05:24 > 0:05:27APPLAUSE AND CHEERING
0:05:27 > 0:05:29Oliver, welcome.
0:05:29 > 0:05:34Just get him docked into the Fact Nav. I'll just get him connected up.
0:05:34 > 0:05:36Right, he's in place.
0:05:36 > 0:05:37Now, I have installed
0:05:37 > 0:05:41the very latest hi-tech Fact Nav 2.0 into Oliver
0:05:41 > 0:05:46and it is crammed with even more facts, millions of them.
0:05:46 > 0:05:51One slight issue did arise, that the instructions for Fact Nav 2.0,
0:05:51 > 0:05:55for installing it, are in Swedish. I know!
0:05:55 > 0:05:58And it turns out that the Swedish for "gently tap"
0:05:58 > 0:06:01is very close for "hammer violently",
0:06:01 > 0:06:03and, yes, there were a few issues
0:06:03 > 0:06:04So it kind of works,
0:06:04 > 0:06:07the only problem we have now is I'm going to need you teams
0:06:07 > 0:06:12to tell me whether the science facts I give you are true or false.
0:06:12 > 0:06:14If they turn out to be true, Oliver will do this...
0:06:14 > 0:06:17HORN HONKS
0:06:17 > 0:06:20And if they're false, Oliver will confirm it by doing this.
0:06:20 > 0:06:23- FOGHORN - OK, simple enough.
0:06:23 > 0:06:29You will see each team has three lights. They're all lit red.
0:06:29 > 0:06:32Every time you answer a question correctly, one of your lights
0:06:32 > 0:06:37will turn green. The first team to light all three lights green wins.
0:06:37 > 0:06:40They win a point, we go onto the next round. Simple as that.
0:06:40 > 0:06:44Just one little fact that you need to consider very carefully,
0:06:44 > 0:06:48because if you answer a question correctly, one light goes green.
0:06:48 > 0:06:52If you answer it wrongly, one of the other team's lights goes green
0:06:52 > 0:06:55so it's quite possible to win the game for them, so be careful.
0:06:55 > 0:06:58Think carefully about your answers, OK?
0:06:58 > 0:06:59We now need, first of all,
0:06:59 > 0:07:02to establish who's going to seize control of the game,
0:07:02 > 0:07:06get the first green light and the first fact question.
0:07:06 > 0:07:08You may not know the exact answer
0:07:08 > 0:07:12but I will give the point to the team that gets closest.
0:07:12 > 0:07:16How many times does an average male heart beat per day?
0:07:16 > 0:07:19The point will go to whoever's nearest, all right?
0:07:19 > 0:07:22So how many times does an average male heart beat per day?
0:07:22 > 0:07:25Yellows, what do you think? What's your answer?
0:07:25 > 0:07:291,500. Reds?
0:07:29 > 0:07:32435.
0:07:32 > 0:07:38Because the real answer is 103,680
0:07:38 > 0:07:41so that means a green light is lit straight away for the Yellows.
0:07:41 > 0:07:43There you go.
0:07:43 > 0:07:46It's a big number.
0:07:46 > 0:07:51A normal male human heart beats about 72 times every minute,
0:07:51 > 0:07:56so that's 103,680 times a day, or almost 38 million times a year.
0:07:56 > 0:08:00So that means the Yellows have seized control of the game.
0:08:00 > 0:08:02They have their first light lit green.
0:08:02 > 0:08:05Don't worry, Reds. You're still in it.
0:08:05 > 0:08:08Right, here comes your science fact.
0:08:08 > 0:08:10Is this true or false?
0:08:10 > 0:08:14No fish can survive out of water...
0:08:14 > 0:08:16No fish can survive out of water.
0:08:16 > 0:08:19Have a chat, because one of you
0:08:19 > 0:08:21might have picked up something that will help.
0:08:21 > 0:08:23No need to write it down.
0:08:23 > 0:08:26While you're thinking, audience, let's see what you think.
0:08:26 > 0:08:29Vote with your feet - is that true or false?
0:08:32 > 0:08:34SIREN WAILS
0:08:34 > 0:08:39That's kind of a united audience. All of you think that's false.
0:08:39 > 0:08:41Everybody here, yes?
0:08:41 > 0:08:47I think maybe because some fish just can survive out of water.
0:08:47 > 0:08:49Yes, well I mean, I did say "no fish", didn't I?
0:08:49 > 0:08:53Yes, maybe there is one. Anybody else have information on this one?
0:08:53 > 0:08:57I think because there are loads of different type of fish in the world
0:08:57 > 0:09:01- and all the fish are different than the others.- So there might be one.
0:09:01 > 0:09:05There's a whole lot of different fish. Audience, back to your places,
0:09:05 > 0:09:08thanks for letting us know what you think. No points for the audience.
0:09:08 > 0:09:12- The people playing for points are our teams. Yellows...- False.
0:09:12 > 0:09:16You think it's false? Yellows think it's false.
0:09:16 > 0:09:18If you get this right, you get two lights lit green.
0:09:18 > 0:09:22If you get it wrong, you're going to put the Reds back in the game.
0:09:22 > 0:09:26It's quite important, not piling on the pressure for you there.
0:09:26 > 0:09:28So, Oliver, is that true or false?
0:09:28 > 0:09:30- FOGHORN - It is false, well done!
0:09:30 > 0:09:35That means another light is lit green for the Yellows, well done!
0:09:37 > 0:09:41Yes. In actual fact, there is a type of fish called the climbing perch
0:09:41 > 0:09:44and it's found in southern and south-east Asia
0:09:44 > 0:09:46and it's able to travel over land
0:09:46 > 0:09:50and it can travel at about 180 metres an hour
0:09:50 > 0:09:52and it can breathe out of water
0:09:52 > 0:09:57because part of its gill works like a tiny little lung.
0:09:57 > 0:10:00Reds, I don't really need to point this out, I'm sure.
0:10:00 > 0:10:03Bright lads, you'll have worked this one out.
0:10:03 > 0:10:06You are under pressure as they have two lights lit green.
0:10:06 > 0:10:08If you get this right, it's one for you.
0:10:08 > 0:10:11- If you get this wrong, what happens?- It turns.
0:10:11 > 0:10:13Yes, it's as simple as that.
0:10:13 > 0:10:17I'm sorry. I'm making it worse for you, but... Because I enjoy it.
0:10:17 > 0:10:19Here is your science fact.
0:10:19 > 0:10:24The sun's energy comes from it making helium.
0:10:24 > 0:10:27The sun's energy comes from it making helium. True or false?
0:10:27 > 0:10:30- ALL: False. - You think it's false.
0:10:30 > 0:10:33That's your answer. They think it's false, that's what they think.
0:10:33 > 0:10:37They've responded by saying they believe it to be false.
0:10:37 > 0:10:41Oliver, is it true or false?
0:10:41 > 0:10:43HORN HONKS
0:10:43 > 0:10:46It's true! The light is lit for the Yellows and they win this round.
0:10:46 > 0:10:49It's 1-0 at the end of the first round.
0:10:49 > 0:10:53- APPLAUSE - That was a really hard fact.
0:10:53 > 0:10:54In fact, the sun's core,
0:10:54 > 0:10:57inside it, nuclear fusion is constantly taking place.
0:10:57 > 0:11:00Every second, it generates the same amount of energy
0:11:00 > 0:11:03as 90 billion tonnes of TNT exploding.
0:11:03 > 0:11:08It's quite a reaction going on and helium is produced as a result,
0:11:08 > 0:11:12So that means at the end of the first round, Yellows take the point.
0:11:12 > 0:11:131-0 to the Yellows.
0:11:28 > 0:11:34I spent a very long time thinking about making my own time machine.
0:11:34 > 0:11:39So one day, I just decided to get on with it and build one.
0:11:39 > 0:11:43Unfortunately, that was the day I had a migraine and I could only
0:11:43 > 0:11:46see out of one eye and I had to use my feet to do the wiring
0:11:46 > 0:11:48because I had pins and needles in my hand.
0:11:48 > 0:11:50So, I mean, it worked...sort of.
0:11:50 > 0:11:52I'm talking, of course, about Mini Miss.
0:11:52 > 0:11:54APPLAUSE AND CHEERING
0:11:58 > 0:12:01If that's what you call a success, Richard,
0:12:01 > 0:12:03I'd hate to see what you class a failure.
0:12:03 > 0:12:07Sorry, Miss. She might look mini, but she's got a mighty brain.
0:12:07 > 0:12:10- Stop gassing, Richard. - And a mighty temper.
0:12:10 > 0:12:13I'll pretend I didn't hear that. Now, today's game is called...
0:12:13 > 0:12:16MANLY VOICE: Balloonacy race.
0:12:16 > 0:12:20- How do you do that?- One team member must ride on the surfboard
0:12:20 > 0:12:23- while the others push.- OK, well I know which one I'd rather be doing.
0:12:23 > 0:12:28- Surf's up, yes!- Do try and concentrate, Richard.- Sorry, Miss.
0:12:28 > 0:12:30The surfboards are on a bed of balloons
0:12:30 > 0:12:33and it's the job of whoever's pushing to take balloons
0:12:33 > 0:12:37from the back to the front as the surfboard travels forwards.
0:12:37 > 0:12:41So this is all about pressure and friction.
0:12:41 > 0:12:44- You're sharp today.- Oh, yes. - Stay away from those balloons.
0:12:44 > 0:12:46Thank you. And I'm also guessing, Miss,
0:12:46 > 0:12:50that the first team to cross that finishing line there wins.
0:12:50 > 0:12:52- That's right.- I am on fire today!
0:12:52 > 0:12:57Teams, we're going to get balloonacy racing. There are a few more rules.
0:12:57 > 0:13:01It's the first team to get the WHOLE of their board across the line,
0:13:01 > 0:13:03not just the front. As you're surfing on balloons,
0:13:03 > 0:13:07some balloons may burst. That might happen... No, that WILL happen.
0:13:07 > 0:13:08When that happens,
0:13:08 > 0:13:11it's the job of whichever team player's at the back of the board
0:13:11 > 0:13:15to dash back to these lab rats and collect a new balloon.
0:13:15 > 0:13:17They will indicate that one has burst
0:13:17 > 0:13:20by putting their little paw in the air, like this...
0:13:20 > 0:13:23There you go! That means a balloon has burst.
0:13:23 > 0:13:27The one at the back of the board runs back and replaces it.
0:13:27 > 0:13:30Surfers, no part of your body is allowed to touch the floor,
0:13:30 > 0:13:32and we will be watching. If the lab rats spot that,
0:13:32 > 0:13:35and they're stupid but quite observant,
0:13:35 > 0:13:36they will indicate it in this way...
0:13:36 > 0:13:40And we will know, OK? We will be watching.
0:13:40 > 0:13:43If all of your balloons burst, stop. Just stop where you are.
0:13:43 > 0:13:46You never know, the other team might burst all of their balloons
0:13:46 > 0:13:50and not get as far as you and you'll still win for getting the furthest.
0:13:50 > 0:13:52- Is everybody clear on the rules? - ALL: Yes.
0:13:52 > 0:13:56- Right, start when you hear this sound.- Surf's up, dude!
0:13:56 > 0:13:59Yes! So when you hear that, it's time to get going.
0:13:59 > 0:14:02Teams, let's get ready to go, let's get ready to surf.
0:14:02 > 0:14:05Always wanted to go surfing. Never have.
0:14:05 > 0:14:08Still not. Oh, yes, the first surfer getting on the board.
0:14:08 > 0:14:11Oh, you're going for a standing up technique.
0:14:11 > 0:14:14- Yes.- OK. If we're ready.
0:14:14 > 0:14:17- Surf's up, dude.- Go! Begin surfing!
0:14:18 > 0:14:20Yes, well, we're away already.
0:14:20 > 0:14:23CHEERING
0:14:23 > 0:14:26Now...
0:14:26 > 0:14:27What this is relying upon...
0:14:27 > 0:14:29This is actually all about friction,
0:14:29 > 0:14:32because if we just put the boards on the floor,
0:14:32 > 0:14:35there'd be too much friction where the board and the floor rub.
0:14:35 > 0:14:38By putting it on balloons, the balloons turn,
0:14:38 > 0:14:41they act like wheels and make it easier.
0:14:41 > 0:14:44It's also about pressure, as they spread their weight across balloons.
0:14:44 > 0:14:47If they put their weight in one place, it will burst,
0:14:47 > 0:14:50just as if I press that much with my hand, it's fine.
0:14:50 > 0:14:53If I put the same pressure in one place, it bursts.
0:14:53 > 0:14:56These guys are doing well.
0:14:56 > 0:14:59Oh, another balloon. Another balloon has popped.
0:14:59 > 0:15:03Oh, oh! Yellows limping home on about two balloons.
0:15:06 > 0:15:09The Reds playing a very, very neat game here.
0:15:09 > 0:15:12They're still on all of their balloons.
0:15:12 > 0:15:16This is really fierce competition.
0:15:16 > 0:15:18Quick, keep pushing.
0:15:18 > 0:15:22Don't forget to steer, lads. You'll hit the stairs there.
0:15:22 > 0:15:25- Steer away from the bridge.- Quick!
0:15:30 > 0:15:31SIREN WAILS
0:15:31 > 0:15:36Oh! Well, that was a very, very close-run thing indeed.
0:15:36 > 0:15:39The Yellows were the first to get their board across, limping home
0:15:39 > 0:15:43on four balloons. The Reds managed to bring their surfboard home
0:15:43 > 0:15:46with all of the balloons still intact, so that means
0:15:46 > 0:15:49another point goes to the Yellows! Well done, well played.
0:15:50 > 0:15:53The standing-up thing looked good though.
0:15:53 > 0:15:57I don't think balloon surfing will become a hot new hobby this summer
0:15:57 > 0:16:00but it got me thinking. If balloons can support that much weight -
0:16:00 > 0:16:06a whole person - can they lift things as well as support them?
0:16:08 > 0:16:12Ninja Nan is keeping watch
0:16:12 > 0:16:15in the security tower at my top-secret base.
0:16:15 > 0:16:18With her super ninja eyesight, nothing escapes her attention,
0:16:18 > 0:16:21especially when it comes to spotting that her tea table
0:16:21 > 0:16:23and tea set aren't in the tower.
0:16:23 > 0:16:29An urgent call goes out to the lab rats to remedy this situation -
0:16:29 > 0:16:30and fast.
0:16:32 > 0:16:35Within just a matter of days,
0:16:35 > 0:16:37they arrive on the scene
0:16:37 > 0:16:40and which method have they chosen to make the delivery?
0:16:40 > 0:16:43Helium-filled balloons, of course.
0:16:43 > 0:16:47But how is that going to work?
0:16:47 > 0:16:48In order to lift the table,
0:16:48 > 0:16:50we need to provide an upwards lift
0:16:50 > 0:16:53that's larger than the downwards pull of gravity,
0:16:53 > 0:16:55keeping the table on the ground.
0:16:55 > 0:16:58Helium is lighter than air and so helium-filled balloons
0:16:58 > 0:17:02tend to float upwards and these can be used to provide the lift.
0:17:02 > 0:17:05So all we need to do is attach enough balloons onto the table
0:17:05 > 0:17:09so the upwards lift is larger than the downwards pull of gravity
0:17:09 > 0:17:13and then our table should be able to float up, up and away.
0:17:13 > 0:17:18OK, so it's not a terrible plan but as Ninja Nan's spotted,
0:17:18 > 0:17:20the weather is not looking pretty.
0:17:20 > 0:17:24In fact, the wind is picking up and dark clouds are gathering.
0:17:24 > 0:17:27The lab rats need to fill enough balloons
0:17:27 > 0:17:29to lift the table and tea set.
0:17:29 > 0:17:31As there are more balloons in the sky,
0:17:31 > 0:17:33the harder it will be to control,
0:17:33 > 0:17:35with each balloon acting like a sail on a boat.
0:17:35 > 0:17:39Will the lab rats succeed in getting Ninja Nan's tea table up to her
0:17:39 > 0:17:42using only helium-filled balloons?
0:17:42 > 0:17:44OK, hold the experiment right there,
0:17:44 > 0:17:46because there is another point up for grabs.
0:17:46 > 0:17:48The score is 2-0 to the Yellows.
0:17:48 > 0:17:52Reds, you can't go into the Messy Messy Mess Test ahead on points.
0:17:52 > 0:17:56But for the honour of winning the point, you should have a go for it,
0:17:56 > 0:17:59and I will give the point to the team who can tell me...
0:17:59 > 0:18:02will it work? Will the lab rats be able to do it
0:18:02 > 0:18:05using helium to lift the table up to Ninja Nan?
0:18:05 > 0:18:09Bear in mind there are some variables here. The weather.
0:18:09 > 0:18:12The weather doesn't look good. Maybe you think the weather's promising.
0:18:12 > 0:18:15The walls. They're rough. They won't be helping.
0:18:15 > 0:18:20And the thing is being operated by lab rats and they're useless,
0:18:20 > 0:18:22so that won't be helping either, OK?
0:18:22 > 0:18:25Let's have your answers. Yellows, what do you think?
0:18:25 > 0:18:28- We don't think it'll work. - You don't think it will work?
0:18:28 > 0:18:31- You don't think it will either? - It won't go right up though.
0:18:31 > 0:18:35You don't think they'll lift the table. Remember the aim of the game
0:18:35 > 0:18:39is to get the table to Ninja Nan for her tea.
0:18:39 > 0:18:42- It will lift but it won't go up to Ninja Nan.- So both teams have agreed
0:18:42 > 0:18:45they're not going to get the table up to Ninja Nan.
0:18:45 > 0:18:46That's your prediction.
0:18:46 > 0:18:50It won't make any difference to the overall score
0:18:50 > 0:18:53but you're after that point just for the honour of winning it.
0:18:53 > 0:18:57There is only one way to find out... Carry on with the experiment.
0:18:59 > 0:19:03So on the windiest day I've seen at my top-secret lab in many years,
0:19:03 > 0:19:07the lab rats have chosen helium balloons as their preferred method
0:19:07 > 0:19:10of delivering a tea table and tea set to Ninja Nan.
0:19:10 > 0:19:12Let's see how they get on.
0:19:14 > 0:19:19OK, so far, so good. They've chosen the right number of balloons.
0:19:19 > 0:19:22The tea table is in the air. We have liftoff...
0:19:22 > 0:19:24but aren't we forgetting something?
0:19:24 > 0:19:27Yes, the tea set. Fools!
0:19:27 > 0:19:30Ah, the first hurdle presenting some problems here,
0:19:30 > 0:19:34as the wind is causing the balloons to bounce all over the place
0:19:34 > 0:19:37which, in turn, is making it impossible to lay the table.
0:19:37 > 0:19:39No big surprises so far then.
0:19:41 > 0:19:44Looks like they're giving up on the tea set part of the deal
0:19:44 > 0:19:49and hoping the tea table alone will be enough to keep Ninja Nan happy.
0:19:49 > 0:19:52I'm not convinced. They're having trouble here.
0:19:52 > 0:19:57The wind is catching the balloons and they are losing control.
0:19:57 > 0:20:01Now a balloon has burst. This is going from bad to worse.
0:20:01 > 0:20:03And that's it. They've thrown in the towel.
0:20:03 > 0:20:08It's all over. Failure, a word they've heard many times before
0:20:08 > 0:20:11and will no doubt hear again.
0:20:11 > 0:20:14Let's be honest, what did any of us expect of my lab rats,
0:20:14 > 0:20:17left to do something on their own?
0:20:17 > 0:20:20It failed. I think the weather wasn't looking good, was it?
0:20:20 > 0:20:24Whilst they had the lift, they didn't have the stability,
0:20:24 > 0:20:27the control, or the brains. All of which means you were both right,
0:20:27 > 0:20:30another point to both teams. The score is 3-1 to the Yellows.
0:20:30 > 0:20:33Well done, both teams.
0:20:33 > 0:20:38OK, it's going to be time soon to get very, very, very messy
0:20:38 > 0:20:41so both teams go off and get changed into your protective suits
0:20:41 > 0:20:45because you're really going to need them in just a moment.
0:20:45 > 0:20:48Yes, good luck.
0:20:48 > 0:20:51Of course, all of this does mean Ninja Nan has been without her tea
0:20:51 > 0:20:53for over eight minutes now.
0:20:53 > 0:20:56Whatever happens next is not going to be pretty.
0:20:56 > 0:20:59I can barely watch...
0:20:59 > 0:21:01but I think we probably should.
0:21:02 > 0:21:05Ninja Nan has not had her cup of tea.
0:21:05 > 0:21:08That means only one thing... Someone has got to pay.
0:21:10 > 0:21:11Nice!
0:21:11 > 0:21:15I did say it was going to get nasty, Have you learned your lesson?
0:21:15 > 0:21:18You can't nod, can you? That hurts too much.
0:21:18 > 0:21:20Just go away and rest and repair.
0:21:20 > 0:21:22I'll need you... Oh, it's going to get worse.
0:21:24 > 0:21:27OK. Well, Ninja Nan made a right mess of him
0:21:27 > 0:21:29but that's OK because now it is time for...
0:21:33 > 0:21:36Where's my Snot Bots? One day, they'll replace my lab rats.
0:21:36 > 0:21:41I built them with an artificial human intelligence
0:21:41 > 0:21:44and it's got so good they've taken on human characteristics so now...
0:21:44 > 0:21:47Whereas before, they would wear any old outfit,
0:21:47 > 0:21:49they now insist that their handbags match their shoes
0:21:49 > 0:21:53and they've caught some pretty hideous colds,
0:21:53 > 0:21:56hence all the snot in the tank.
0:21:56 > 0:21:59But that's OK because we have medicine in the form of prize discs
0:21:59 > 0:22:03hidden in the tank. Teams, it's your job to get those prize discs
0:22:03 > 0:22:06into the Snot Bots and cure their colds.
0:22:06 > 0:22:10The team that gets the most prize discs into their Snot Bot
0:22:10 > 0:22:12will win the prizes written on them.
0:22:12 > 0:22:17Right now, Yellows are in the lead, the score 3-1,
0:22:17 > 0:22:19so you get a five-second head start.
0:22:19 > 0:22:20You have some time
0:22:20 > 0:22:24to get as many prize discs into the mouth of your Snot Bot as possible
0:22:24 > 0:22:26and that some time starts...now.
0:22:28 > 0:22:33So, it's the Yellows with the upper hand, but will they make it count?
0:22:33 > 0:22:35And the Reds burst into life
0:22:35 > 0:22:38but the Yellows have one disc to their name already.
0:22:38 > 0:22:41- Urgh!- A lot of support for the Yellows, it seems here today.
0:22:41 > 0:22:44Will this have an effect on the outcome?
0:22:47 > 0:22:49The Reds already have a disc there and it's in.
0:22:49 > 0:22:52A slow start from both teams here today,
0:22:52 > 0:22:56- acting as if they have all the some time in the world.- Get it!
0:22:56 > 0:23:00- The scores at this stage - one apiece.- Is it yellow?
0:23:00 > 0:23:04Oh, looks like it's the Yellows making the next decisive move.
0:23:04 > 0:23:09Yes, it's 2-1 to the Yellows. Look at that! Will you look at that!
0:23:09 > 0:23:12There was literally nothing happening right before our eyes.
0:23:12 > 0:23:16Blink...and you might not miss anything.
0:23:16 > 0:23:20Some time racing away with us here at the septic tank
0:23:20 > 0:23:23but the teams are remaining calm under pressure.
0:23:23 > 0:23:26- That's it, that's it!- Yes, got one!
0:23:26 > 0:23:30The Reds are denied another there by the grilled dentures of my Snot Bot.
0:23:30 > 0:23:33- Quick, do it!- But their patience pays off and they come back
0:23:33 > 0:23:35with a double whammy of two prize discs.
0:23:35 > 0:23:39But will it be enough to win the game?
0:23:39 > 0:23:42Who can tell at the moment?
0:23:44 > 0:23:46SIREN WAILS
0:23:46 > 0:23:51Your some time is up, teams. Are you all still in there?
0:23:51 > 0:23:54Yes, you are all there. It's not nice, I know.
0:23:54 > 0:23:57What we must now do is find out who's won, so lab rats,
0:23:57 > 0:24:00if you count them up for me, please. Yellows, what do we have?
0:24:00 > 0:24:04Five. Five for the Yellows, that's a high score, OK.
0:24:04 > 0:24:06For the Reds, what do we have?
0:24:06 > 0:24:10- ALL: Yes!- Whoa, six for the Reds, that means the red team have won.
0:24:12 > 0:24:15That was close. The Yellows had a head start but the Reds won.
0:24:15 > 0:24:17Let's find out what the Reds have won.
0:24:17 > 0:24:20Each of you will be taking home... a land yacht...
0:24:20 > 0:24:23APPLAUSE AND CHEERING
0:24:23 > 0:24:24a practical joke set...
0:24:24 > 0:24:27APPLAUSE AND CHEERING
0:24:27 > 0:24:28a magnetic rocket racer...
0:24:28 > 0:24:30APPLAUSE AND CHEERING
0:24:30 > 0:24:33- a solar butterfly... - APPLAUSE AND CHEERING
0:24:33 > 0:24:35Don't know what it is but it sounds lovely.
0:24:35 > 0:24:37..a personal room moon...
0:24:37 > 0:24:39and a Slinky.
0:24:39 > 0:24:41- APPLAUSE AND CHEERING - For each...
0:24:41 > 0:24:45That is quite a haul of prizes that the Reds will be taking home,
0:24:45 > 0:24:48each member of the team. Now the slightly trickier bit, Yellows.
0:24:48 > 0:24:52Here's the things that you would each have won.
0:24:52 > 0:24:55- A solar butterfly for each of you. - ALL: Aww!
0:24:55 > 0:24:59- Yes, I know. A skeleton model, yes. - ALL: Aww!- Yes, each of you.
0:24:59 > 0:25:00A personal room moon.
0:25:00 > 0:25:02you'd each have been taking those home.
0:25:02 > 0:25:05- A land yacht. Nice. - ALL: Aw!
0:25:05 > 0:25:07And the magnetic rocket racer.
0:25:07 > 0:25:11Of course, on Blast Lab, only one team can go home
0:25:11 > 0:25:14with a big sack of prizes. The losing team still gets the big sack,
0:25:14 > 0:25:18it's just that their prizes are in the form of dust and ash
0:25:18 > 0:25:20because it is time for Bidet Goes Bang.
0:25:28 > 0:25:32Right, Reds, you went into the Messy Messy Mess Test at a disadvantage
0:25:32 > 0:25:34and you blitzed it, that was astonishing, well done.
0:25:34 > 0:25:37All of this lot coming home with you now.
0:25:37 > 0:25:40You'll be feeling pleased, happy. Yes, day's gone well!
0:25:40 > 0:25:43Yellows, you went into the Messy Messy Mess Test with the lead
0:25:43 > 0:25:48and actually you got five, that was a really good score still.
0:25:48 > 0:25:50So these guys were just... Well, they won.
0:25:50 > 0:25:53Still, it's OK because now, waiting for you, is...
0:25:53 > 0:25:55It's the walk of shame. That's what it is.
0:25:55 > 0:26:00Follow me, team, follow me. Come with me, come with me, come on.
0:26:00 > 0:26:04- Comfort them, they are sad. - ALL: Aw!
0:26:17 > 0:26:19Guys, it's just...
0:26:19 > 0:26:23bad luck, but it's nearly as good as taking your prizes home with you,
0:26:23 > 0:26:27blowing them, up, isn't it..? Isn't it?
0:26:27 > 0:26:30- Nearly? Joshua?- No.- OK, OK.
0:26:30 > 0:26:33So let's get on with it. Right, you know the drill.
0:26:33 > 0:26:37Lift the handle and let's get ready.
0:26:37 > 0:26:40OK, audience, we're going to count them down.
0:26:40 > 0:26:42Lift it up, lift it up. There you go. Wait, wait, wait.
0:26:42 > 0:26:45Audience, we'll count them down from five.
0:26:45 > 0:26:51ALL: Five, four, three, two, one.
0:26:51 > 0:26:53Go!
0:26:53 > 0:26:55Yellows, you were great.
0:26:55 > 0:27:00Thanks for coming into the Blast Lab, I'm sorry you lost.
0:27:00 > 0:27:02That's about it for now.
0:27:02 > 0:27:04We've learned all about air pressure the fun way,
0:27:04 > 0:27:08by messing about with balloons, helium and Ninja Nan's table.
0:27:08 > 0:27:10But sadly, all good things must come to an end.
0:27:10 > 0:27:14Although, I do have a design for a never-ending choc ice around here.
0:27:14 > 0:27:17I'll see if I can find it before next time. Bye for now!
0:27:17 > 0:27:18APPLAUSE AND CHEERING
