0:00:34 > 0:00:36THEY CHEER
0:00:36 > 0:00:39Lab coat. My lab coat!
0:00:41 > 0:00:45You do not want to see what is back there.
0:00:45 > 0:00:48You don't. I was tinkering with my space time portal late last night
0:00:48 > 0:00:53and just as I was turning it off, something horrible slipped through.
0:00:54 > 0:00:55From another dimension.
0:00:55 > 0:00:59I don't know what it was or where it came from or how to send it back.
0:00:59 > 0:01:02Let's just hope that door is strong enough to keep it away.
0:01:02 > 0:01:05FIERCE ANIMAL NOISE
0:01:05 > 0:01:09It's a pain. Anyway, I'm Richard and this is my Blast Lab.
0:01:09 > 0:01:11THEY CHEER
0:01:13 > 0:01:15Very soon, we shall be meeting two teams
0:01:15 > 0:01:18who claim to be science boffins. We'll see about that.
0:01:18 > 0:01:21They'll be competing in some top-level scientific games
0:01:21 > 0:01:24and hoping to win prizes. Here's what's coming up.
0:01:24 > 0:01:26- MONSTER CRIES OUT - Sorry.
0:01:39 > 0:01:42Now, this laboratory is so top secret
0:01:42 > 0:01:46that I've got to have a team of crack SAS men to protect it 24/7.
0:01:46 > 0:01:48Unfortunately, they couldn't make it today.
0:01:48 > 0:01:52One of them has a veruca and the others don't want to catch one,
0:01:52 > 0:01:55so I've brought along someone who isn't scared of verucas.
0:01:55 > 0:01:57In fact, they're scared of her.
0:01:57 > 0:01:58It is my Ninja Nan.
0:02:07 > 0:02:10Thanks for standing in, Ninja Nan.
0:02:10 > 0:02:15I know she may look fragile but she is a fully trained ninja.
0:02:19 > 0:02:23See? Right. Nan, if you'd like to take your place in security.
0:02:23 > 0:02:26Take your place... Nan, could you take your place in security?
0:02:26 > 0:02:27Thank you very much.
0:02:27 > 0:02:31Her reactions are so quick, she can catch bullets with her teeth.
0:02:31 > 0:02:33They're false teeth but they are her teeth.
0:02:33 > 0:02:37Ninja Nan, have you settled in to security? Oh, look, she's there.
0:02:37 > 0:02:39She's made it, pulling her ninja trolley.
0:02:39 > 0:02:42That's a special ninja tartan there.
0:02:42 > 0:02:44And she's got... Oh, she's got her knitting with her.
0:02:44 > 0:02:48That's nice. She's knitting herself a woolly camouflage suit
0:02:48 > 0:02:51so she can sneak around undetected at car boot sales.
0:02:51 > 0:02:53Let's see who's trying to get into my lab today.
0:02:53 > 0:02:57Somewhere there's a bunch of people to claim to be the Yellow Team.
0:02:58 > 0:03:01Well, you see, you're applauding.
0:03:01 > 0:03:04They say they're the Yellow Team. We must be careful.
0:03:04 > 0:03:07This is a top secret lab, so I've got my security files here to check.
0:03:07 > 0:03:09Identify yourselves by name, please.
0:03:09 > 0:03:11- Tammy.- Corey.
0:03:11 > 0:03:13- Carys.- Tammy. Corey. Carys.
0:03:13 > 0:03:15Yes. That checks out OK.
0:03:15 > 0:03:19Right. It says down here, Carys, you have a hidden talent.
0:03:19 > 0:03:21- Yeah.- I need you to prove that
0:03:21 > 0:03:24so we can check you through security. What is that talent?
0:03:24 > 0:03:28- I can tell jokes.- Really? - Yes.- Go on.- Knock knock.
0:03:28 > 0:03:31- Who's there?- The interrupting sheep.
0:03:31 > 0:03:35- The interrupting...- Baa-aa! - Is that a joke? It's borderline.
0:03:35 > 0:03:40What do we think? Sorry. We need more security checks, Yellow Team.
0:03:40 > 0:03:43Carys, it also says here that you can say...
0:03:43 > 0:03:47now this I don't believe... the longest place name in Wales.
0:03:47 > 0:03:50- Can you?- Yes.- Prove it.
0:03:50 > 0:03:54Llanfairpwllgwyngyllgogery chwyrndrobwlllantysiliogogogoch.
0:03:54 > 0:03:57Do you need a tissue after that? That's amazing.
0:03:57 > 0:04:00It's worth a round of applause because you are the Yellow Team.
0:04:00 > 0:04:03Come through, past Ninja Nan.
0:04:05 > 0:04:08OK, you've proved yourselves. You are the Yellow Team.
0:04:08 > 0:04:10You are welcome to our top secret underground lab.
0:04:10 > 0:04:14- Where are you from?- We're from Wales and we're the Camera Queens.
0:04:14 > 0:04:17You're not. You're the Yellow Team but thank you for coming in.
0:04:17 > 0:04:21Let's meet the bunch of people who claim to be the Reds.
0:04:23 > 0:04:27Again, audience, we can't just let anybody in here with us.
0:04:27 > 0:04:29Before you can go through security,
0:04:29 > 0:04:31identify yourselves, please, by name.
0:04:31 > 0:04:33- Kyle.- James.- Josh.
0:04:33 > 0:04:35Kyle. James. Josh. Yes. That checks out.
0:04:35 > 0:04:38Josh, it says here you have a hidden talent. What is it?
0:04:38 > 0:04:40I can do a backwards body worm.
0:04:40 > 0:04:42Right. Do one, then.
0:04:44 > 0:04:46Well, I guess that is a backwards body worm.
0:04:46 > 0:04:49Yeah, you are the Red Team. Come through security.
0:04:53 > 0:04:55OK. On that basis, we trust you.
0:04:55 > 0:04:58You are the Red Team. Where are you from?
0:04:58 > 0:05:02We're from Suffolk and we're the Boffin Squad.
0:05:02 > 0:05:04Very clever, but irrelevant. You're the Red Team.
0:05:04 > 0:05:09Time for both teams to make your way to the positions for the first game.
0:05:09 > 0:05:12You go and get ready for the first game. Away you go.
0:05:12 > 0:05:16And to help me out, I'd like to introduce a good friend of mine.
0:05:16 > 0:05:18He is the original smart car - Oliver.
0:05:35 > 0:05:39Now, Oliver loves nothing more than collecting fact for his
0:05:39 > 0:05:43sophisticated hi-tech in-car Fact Now system.
0:05:43 > 0:05:46Unfortunately, those facts are not always correct.
0:05:46 > 0:05:50It's up to our two teams to decide which are false and which are true.
0:05:50 > 0:05:52Oliver will then let us know.
0:05:52 > 0:05:54If it's true, he'll do this.
0:05:54 > 0:05:56SIREN WAILS, HORN HOOTS
0:05:56 > 0:05:59But if it's false, he'll do this.
0:05:59 > 0:06:01FOGHORN BLASTS
0:06:01 > 0:06:04OK. Teams, here are your facts.
0:06:04 > 0:06:08Red Team, you first. I need you to tell me if this is true or false.
0:06:08 > 0:06:11A hurricane three times the size of earth
0:06:11 > 0:06:16has been raging on Jupiter for over 300 years. Talk it over.
0:06:16 > 0:06:19Let's see what the audience think.
0:06:19 > 0:06:22Hands up. Shout it out, audience.
0:06:22 > 0:06:24SHOUTING
0:06:24 > 0:06:27I reckon most of the audience are going for true.
0:06:27 > 0:06:29There's quite a few guessing false.
0:06:29 > 0:06:33- Have you made your mind up?- Yeah. - Is it true or false?- It's true.
0:06:33 > 0:06:38Oliver is going to tell us. Oliver, is it true or false? It's true!
0:06:38 > 0:06:39Well done!
0:06:41 > 0:06:44That actually is the storm that causes the red spot
0:06:44 > 0:06:47on the surface of Jupiter.
0:06:47 > 0:06:49Right. Yellows, here comes your fact.
0:06:49 > 0:06:55In the 1830s, tomato ketchup was sold as a shampoo.
0:06:55 > 0:06:58Have a think. I'm going to ask the audience what they think.
0:06:58 > 0:07:00What do you reckon?
0:07:00 > 0:07:03ALL: False!
0:07:03 > 0:07:06Overwhelmingly thinking false there.
0:07:06 > 0:07:08Have you made your mind up?
0:07:08 > 0:07:12- That was quick. So what do you think?- False.
0:07:12 > 0:07:19Oliver, is it true or false? False. Well done, that's a point!
0:07:19 > 0:07:23It was actually sold as a medicine to strengthen the blood.
0:07:23 > 0:07:27It was known as Dr Miles' Compound Extract Of Tomato,
0:07:27 > 0:07:31so you could ask for that next time you have chips. One last question.
0:07:32 > 0:07:34I don't need you to tell me if it's true or false.
0:07:34 > 0:07:39I want you to write that answer on the board in front of you
0:07:39 > 0:07:40and then hold it up.
0:07:40 > 0:07:43I will give the point to the team that's nearest.
0:07:43 > 0:07:44Here comes the question.
0:07:44 > 0:07:46A long time ago,
0:07:46 > 0:07:51there were no ice caps and Alaska was as warm as California is today.
0:07:51 > 0:07:54But how many million years ago was this?
0:07:54 > 0:07:57Work out an answer, teams. Have a think.
0:07:57 > 0:08:00Audience, have you got any ideas? Any clues?
0:08:00 > 0:08:04I'm going to bring my microphone. It's disguised as a mug tree.
0:08:04 > 0:08:06What do you think?
0:08:06 > 0:08:09- How many years ago?- Eight.
0:08:09 > 0:08:11- Eight years ago.- Yeah.
0:08:11 > 0:08:14We'd have noticed that. How old are you?
0:08:14 > 0:08:17- Nine.- You'd have noticed that. Any other answers?
0:08:17 > 0:08:20- Polar ice caps weren't there... - About seven million years ago.
0:08:20 > 0:08:25Eight to seven million, that's quite a range. Teams, are we ready?
0:08:25 > 0:08:28I shall put away my mug-tree microphone.
0:08:28 > 0:08:31I think it's a brilliant invention.
0:08:31 > 0:08:34- Right. Teams, have you got your answers ready?- Yes.
0:08:34 > 0:08:37Turn around so we can all see. Hold them up.
0:08:37 > 0:08:41Hold them up. So, Reds, you've gone for six million years.
0:08:41 > 0:08:45Yellows, 5.5 million years. That's very close answers there.
0:08:45 > 0:08:47Very close answers. The real answer is...
0:08:47 > 0:08:53100 million, which means the Reds are the closest. You get the point!
0:08:53 > 0:08:55CHEERING
0:08:55 > 0:08:58You were the closest, you win the point,
0:08:58 > 0:09:01and at the end of that round, the scores are 2-1 to the Reds.
0:09:01 > 0:09:05You're in the lead. Well done. Loads of time left.
0:09:17 > 0:09:20That's all to come. Now it is time for mini science.
0:09:20 > 0:09:23I'll be asking our teams
0:09:23 > 0:09:26to conduct an experiment using ordinary household objects.
0:09:26 > 0:09:28To make sure they're doing it right,
0:09:28 > 0:09:32I've brought my old science teacher back through time to help.
0:09:32 > 0:09:34There may have been a teensy mistake, though.
0:09:34 > 0:09:37You see, when she entered my time machine,
0:09:37 > 0:09:39she was 65 years old but when she stepped out again,
0:09:39 > 0:09:42she was just ten. It is, of course, Mini Miss!
0:09:46 > 0:09:47Richard, where's your tie?
0:09:47 > 0:09:49Sorry, miss, left it at home.
0:09:49 > 0:09:53- Your mother will be hearing about this.- I'm sorry!
0:09:53 > 0:09:55What are we doing today, miss?
0:09:55 > 0:09:57DRONING
0:09:57 > 0:10:00The water wheel must have stopped working again.
0:10:00 > 0:10:04This lab is very green. It's powered by that water wheel outside,
0:10:04 > 0:10:07but as a result, it's often very dark as well as very green.
0:10:07 > 0:10:10Ninja Nan? Ninja Nan?
0:10:10 > 0:10:12On the bike, please. We need power.
0:10:12 > 0:10:17On the bike. That's what it's there for. She can move when she has to.
0:10:17 > 0:10:18Thank you, Nan.
0:10:19 > 0:10:21Back to today's experiment.
0:10:21 > 0:10:25Today's teams are going to be making a vitamin C rocket
0:10:25 > 0:10:28by using some empty small pots,
0:10:28 > 0:10:34some water, some tablets and an angled launch pad.
0:10:34 > 0:10:36Each team will get three attempts
0:10:36 > 0:10:39and the team that gets their rocket to go furthest wins.
0:10:39 > 0:10:42That's fantastic. How do they make this rocket?
0:10:42 > 0:10:47Since we are making rockets, everyone has to put their safety goggles on.
0:10:47 > 0:10:50Yeah. That's probably a good idea, rockets and goggles, I reckon.
0:10:50 > 0:10:53Mind you, miss, they look great.
0:10:53 > 0:10:54Thank you, Richard.
0:10:54 > 0:10:56So what do we do?
0:10:56 > 0:10:59To make the rockets, the teams have to put the water
0:10:59 > 0:11:04- and the vitamin C tablet into this small pot.- Right.
0:11:04 > 0:11:08Then shut the lid. The teams could use whatever combination of water
0:11:08 > 0:11:11and tablets they'd like and they can also change
0:11:11 > 0:11:12the angle of the launch pad.
0:11:12 > 0:11:15OK. OK. So there's a lot of variables in there.
0:11:15 > 0:11:18Once the teams have put the water and the vitamin C tablet
0:11:18 > 0:11:21into the small pot, they then have to shut the lid
0:11:21 > 0:11:25very quickly and stick it onto the launch pad.
0:11:25 > 0:11:28So they stick that there as the rocket on there...
0:11:28 > 0:11:31And on the scoring, when your rocket goes off,
0:11:31 > 0:11:34the lid will fire here across into the target zone.
0:11:34 > 0:11:37Wherever it lands, not where it slides to,
0:11:37 > 0:11:39where the lid lands is as far as you've got.
0:11:39 > 0:11:41A lab rat will then come in and mark it with a flag.
0:11:41 > 0:11:46The team that gets their lid the furthest,
0:11:46 > 0:11:49their rocket the furthest, wins the point.
0:11:49 > 0:11:54I'm now going to demonstrate but I'm going to hide my combination
0:11:54 > 0:11:57and do it on the table so that none of the teams can see.
0:11:57 > 0:11:59That's very secretive, miss.
0:11:59 > 0:12:02First of all, I'm going to add the water.
0:12:03 > 0:12:06So an undisclosed secret amount of water has gone in there.
0:12:06 > 0:12:08Are you following this?
0:12:08 > 0:12:11So some water in there but you're not saying how much.
0:12:11 > 0:12:14I have also prepared a tablet that was in my pocket.
0:12:14 > 0:12:18- So you're not saying it's a half, a quarter or a whole one.- No.
0:12:18 > 0:12:20She's smart, you see, my teacher.
0:12:20 > 0:12:22- And now... - Stand well back.- Stand back.
0:12:22 > 0:12:26What happens now?
0:12:26 > 0:12:28Well, it works, miss. It does work.
0:12:28 > 0:12:31I'm slightly frightened. That is brilliant.
0:12:31 > 0:12:33Reds, you're in the lead,
0:12:33 > 0:12:37which means you get to choose whether you go first or second.
0:12:37 > 0:12:39- What do you want to do?- Second.
0:12:39 > 0:12:42If we're ready, then. Yellow Team, go.
0:12:45 > 0:12:46What are you going to do?
0:12:46 > 0:12:51We're going to use the half tablet and half the water.
0:12:51 > 0:12:55So we're going to put the water in first to make your rocket fuel.
0:12:55 > 0:12:58OK. That's just about half full of water.
0:12:58 > 0:13:01Next thing to decide before you launch
0:13:01 > 0:13:04is which angle you're going to have your launch pad at.
0:13:04 > 0:13:09This is the sort of middle. It can go higher than that or lower.
0:13:09 > 0:13:11- Higher.- You think higher.- Yeah.
0:13:11 > 0:13:14Lab rat, higher, please.
0:13:15 > 0:13:18You've got to lower the tablet in, get the lid on.
0:13:18 > 0:13:22Put it on the launch area and we'll see what happens.
0:13:22 > 0:13:24Well done. Very good work.
0:13:24 > 0:13:27Right. Now we all wait.
0:13:27 > 0:13:32And a good score straightaway. That landed in the six zone.
0:13:32 > 0:13:33Well done!
0:13:34 > 0:13:35Well done.
0:13:40 > 0:13:43- What we doing to do? - We're going to put a whole tablet.
0:13:43 > 0:13:49A whole tablet going in but half water. Same water, more tablet.
0:13:49 > 0:13:52- We've got to decide on the launch pad.- Keep it where it is.
0:13:52 > 0:13:53OK, OK.
0:14:02 > 0:14:05Whoa! Well, it was a very fast launch there.
0:14:05 > 0:14:06Into the four zone.
0:14:06 > 0:14:09The Yellows are still ahead. Well done, Reds, though.
0:14:13 > 0:14:16When those tablets are mixed with water, they start to fizz.
0:14:16 > 0:14:18Fancy name for that is effervescence.
0:14:18 > 0:14:22And that means it's releasing gas into the space above the water
0:14:22 > 0:14:25and eventually, there just isn't enough room for any more gas
0:14:25 > 0:14:28and the lid can't take it any more and it flies off.
0:14:28 > 0:14:31Real rockets work in the same sort of way.
0:14:31 > 0:14:33They don't load them with vitamin C
0:14:33 > 0:14:36and stick them to a board of Velcro, but when those engines
0:14:36 > 0:14:38make that huge explosion,
0:14:38 > 0:14:42they're releasing gas and that's what's pushing them up into space.
0:14:42 > 0:14:45So this is rocket science we're doing. It is. Right.
0:14:45 > 0:14:49You must have come to a decision now. It's your second launch.
0:14:49 > 0:14:52- What are you going to do? - Full water and full tablet.
0:14:52 > 0:14:54Good luck.
0:15:03 > 0:15:05Whoa!
0:15:05 > 0:15:09I think it was just behind that but that was a good successful launch.
0:15:13 > 0:15:15Reds, step forwards.
0:15:15 > 0:15:17Time for your second launch.
0:15:17 > 0:15:21We're going to have full water and half tablet.
0:15:21 > 0:15:24- What about the launch pad angle? - We're going to move it down.
0:15:24 > 0:15:28That hasn't been moved yet. There's middle or there's low.
0:15:28 > 0:15:29Middle. Middle.
0:15:29 > 0:15:31Lab rat, middle.
0:15:31 > 0:15:33So, full water, half...
0:15:33 > 0:15:35This has never been done.
0:15:39 > 0:15:40It's nail biting.
0:15:40 > 0:15:43There's nothing we can do but watch.
0:15:43 > 0:15:45There we go. We're away.
0:15:45 > 0:15:47It's building up power. It's building up power.
0:15:47 > 0:15:49That gas is building up and firing it.
0:15:49 > 0:15:52That was a very good go and that was a good shot.
0:16:00 > 0:16:01What are you going to do?
0:16:01 > 0:16:03This is your last attempt.
0:16:03 > 0:16:06We're going to keep that the same
0:16:06 > 0:16:08and we're going to try the same one we did.
0:16:08 > 0:16:10Half water, half tablet.
0:16:10 > 0:16:12Why are you sticking with that?
0:16:12 > 0:16:16- Maybe the further back it is, maybe the further it goes.- Good luck.
0:16:16 > 0:16:19Hope you have a successful launch.
0:16:25 > 0:16:28Good co-ordinated work on the launch there. That helps.
0:16:28 > 0:16:29We're building up power.
0:16:39 > 0:16:42- You have everything to play for now, Reds.- Yeah.
0:16:42 > 0:16:44That point is still up for grabs.
0:16:44 > 0:16:46But you're going to have to beat that
0:16:46 > 0:16:49and it was an almighty rocket launch.
0:16:49 > 0:16:56- Any ideas?- We're going with quarter water and...- Quarter tablet.
0:16:56 > 0:16:58And half water.
0:16:58 > 0:17:01- And what you going to do about the angle?- I think we should leave it.
0:17:01 > 0:17:03All right. Good luck.
0:17:03 > 0:17:04This is the last one.
0:17:04 > 0:17:08If the Reds don't get further than that, the point goes to Yellows.
0:17:08 > 0:17:10Go on, Josh.
0:17:13 > 0:17:16We're waiting. Come on, Reds. This is crucial.
0:17:16 > 0:17:19This is the point for you.
0:17:21 > 0:17:25It was a huge launch but I don't think you were quite there!
0:17:29 > 0:17:32Reds, that couldn't have been any closer, it really couldn't,
0:17:32 > 0:17:36but Yellows, the point still goes to you. Well done to the Yellows.
0:17:39 > 0:17:41So that means the score is two-all.
0:17:41 > 0:17:43It is a draw right now.
0:17:43 > 0:17:47Some of those lids move pretty fast when they're launched.
0:17:47 > 0:17:51I reckon if we scaled things up a bit, we might not actually get
0:17:51 > 0:17:53the blast lab into orbit,
0:17:53 > 0:17:56but we could move something bigger, say, a tennis ball.
0:17:58 > 0:18:01Tennis was invented in the 19th century
0:18:01 > 0:18:04by two posh men on a lawn.
0:18:04 > 0:18:07The record for the fastest serve in tennis
0:18:07 > 0:18:14is 153 mph, held by an angry American called Andy.
0:18:14 > 0:18:17We think we can do better.
0:18:32 > 0:18:34Well practised in pushing back the boundaries
0:18:34 > 0:18:37of both endurance and clothes sense,
0:18:37 > 0:18:41these hero lab rats have volunteered to help us in our endeavours.
0:18:41 > 0:18:45Years of military training and countless seconds in the gym
0:18:45 > 0:18:50have produced these ultimate examples of the human form.
0:18:50 > 0:18:52A sight to behold.
0:18:53 > 0:18:55Let's see what they can do.
0:18:56 > 0:19:00It's safe to say we're not going to break any records with these two.
0:19:00 > 0:19:02We need more accuracy.
0:19:02 > 0:19:04We need more power.
0:19:04 > 0:19:07We need an expert.
0:19:07 > 0:19:10Who is this strange-looking figure appearing from nowhere
0:19:10 > 0:19:12to steal the lab rats' glory?
0:19:12 > 0:19:15And why is he carrying a drainpipe?
0:19:15 > 0:19:18Hello. I'm a spud launcher expert.
0:19:18 > 0:19:21Spud launchers use compressed air
0:19:21 > 0:19:23as the source of energy to fire the projectile.
0:19:23 > 0:19:25In this case, a tennis ball.
0:19:25 > 0:19:27When the trigger is pulled,
0:19:27 > 0:19:30a valve releases the compressed gas into the barrel
0:19:30 > 0:19:34where it rapidly expands, shooting the ball out at ridiculous speed.
0:19:34 > 0:19:37Luckily, lab rats are stupid creatures
0:19:37 > 0:19:39bred especially for this sort of thing.
0:19:39 > 0:19:43This isn't something a normal person should ever attempt.
0:19:43 > 0:19:46Three. Two. One.
0:19:46 > 0:19:47Fire!
0:19:51 > 0:19:53Oh, dear.
0:19:53 > 0:19:57Poor, deluded lab rat. And to think that was on the lowest setting.
0:19:57 > 0:20:00Take him off the course so we can hand
0:20:00 > 0:20:03this world record bid over to the professionals.
0:20:05 > 0:20:07Our spud launcher expert
0:20:07 > 0:20:12is going to turn the compressed air up to full power.
0:20:17 > 0:20:21Now we shall see what he's made of.
0:20:21 > 0:20:24Hold it there because there's an extra point at stake for you.
0:20:24 > 0:20:28Bearing in mind it's 2-2 right now, you need this point.
0:20:28 > 0:20:32Do you think they'll break the world record or not? Red Team.
0:20:32 > 0:20:35- We think they'll fail.- Yellows?
0:20:35 > 0:20:40- Fail.- You think fail as well? OK. Well, let's find out if they do it.
0:20:42 > 0:20:44We're turning the power up to full
0:20:44 > 0:20:51to see if our expert can better Andy Roddick's record serve of 153 mph.
0:20:51 > 0:20:543...2...1...Fire!
0:20:59 > 0:21:00So close!
0:21:00 > 0:21:03Just 7 mph slower than the record.
0:21:03 > 0:21:07So, no world record but this got me thinking.
0:21:07 > 0:21:09With all this power at our disposal,
0:21:09 > 0:21:13shouldn't we try and do something really important?
0:21:13 > 0:21:17But what's more important than setting a new world record?
0:21:17 > 0:21:19Of course! Chips.
0:21:19 > 0:21:24Prepare for a brand new tennis stroke. The chip shot.
0:21:32 > 0:21:34Finally, success.
0:21:34 > 0:21:40Cold, uncooked chips. The food of champions.
0:21:42 > 0:21:44There we go, they failed, that means you get a point
0:21:44 > 0:21:46and you get a point,
0:21:46 > 0:21:48so you're on 3 points apiece.
0:21:51 > 0:21:53Both teams need to take your 3 points and get ready,
0:21:53 > 0:21:56into your protective suits for the messy, mess test
0:21:56 > 0:21:57which is next.
0:21:57 > 0:22:02Just one thing. Not only did my lab rats fail to break the record
0:22:02 > 0:22:06for the fastest serve, they then also used all that hi-tech
0:22:06 > 0:22:09expensive equipment to make chips.
0:22:09 > 0:22:12I don't know about you, that doesn't seem right. Lab rat!
0:22:12 > 0:22:17Lab rat! I think my Ninja Nan needs a rest on that bike
0:22:17 > 0:22:19giving us all our power, so on you get.
0:22:19 > 0:22:21It's your turn to get pedalling.
0:22:21 > 0:22:23That's it. OK, Nan.
0:22:23 > 0:22:25You can get off and have a rest.
0:22:25 > 0:22:29Not that you need a rest, you're a Ninja. Lab rat, start pedalling.
0:22:29 > 0:22:32Pedal faster. Pedal properly. There you go, now.
0:22:32 > 0:22:34Just keep going until I tell you to stop.
0:22:34 > 0:22:37Which I probably won't, cos it's time for us to move on
0:22:37 > 0:22:39to the messy, messy, mess test.
0:22:42 > 0:22:45Which, today, is in the nuclear box and that's why you guys
0:22:45 > 0:22:47needed the protective suits on.
0:22:47 > 0:22:50- Are you all comfortable in there? - Yeah.- Right. This is the game.
0:22:50 > 0:22:53Each of these pods here contains a fabulous prize.
0:22:53 > 0:22:57Weather forecast watch, MP3 player, set of Robo-bugs.
0:22:57 > 0:23:01The idea is to move them from here across to the other end of the box.
0:23:01 > 0:23:03Obviously, you can't use your hands
0:23:03 > 0:23:04cos they'd melt and drop off.
0:23:04 > 0:23:07That's why you've got these tongs to handle them.
0:23:07 > 0:23:11You pass them from one to the other, very carefully. Don't drop it.
0:23:11 > 0:23:14If you drop it, it's out the game. Leave it where it is.
0:23:14 > 0:23:16Players on the end, your job when it arrives with you,
0:23:16 > 0:23:18turn round and put it in the basket.
0:23:18 > 0:23:21The team to move the most prizes across the nuclear box
0:23:21 > 0:23:23gets to take them home.
0:23:23 > 0:23:26But the losing team has to blow their prizes up.
0:23:26 > 0:23:29The score right now is 3-3
0:23:29 > 0:23:31so there is no five second advantage, today.
0:23:31 > 0:23:33When you hear the nuclear alert,
0:23:33 > 0:23:37both teams can start at the same time, so you've got some time
0:23:37 > 0:23:40to get as many of the prize pods across the box as possible.
0:23:40 > 0:23:43If you drop one it's out of the game. We will be watching.
0:23:43 > 0:23:44And that time starts...
0:23:44 > 0:23:48Are you all ready? That time starts...now!
0:23:48 > 0:23:50CHEERING AND SHOUTING
0:23:50 > 0:23:52So, both teams off to a flying start
0:23:52 > 0:23:56in my disgusting nuclear box gunge tank.
0:24:00 > 0:24:03The Yellows' passing skills are looking good,
0:24:03 > 0:24:08but they seem more than a little reluctant to let go of the pod.
0:24:08 > 0:24:10No such trouble for the Reds, though.
0:24:10 > 0:24:12I guess part of the problem here
0:24:12 > 0:24:16is it's not the kind of thing any of our players
0:24:16 > 0:24:18are likely to have practised.
0:24:18 > 0:24:21Not much call for this sort of thing,
0:24:21 > 0:24:24but they're getting some practice now.
0:24:33 > 0:24:36The Reds take the lead and set the pace
0:24:36 > 0:24:39while the Yellows are taking some time about things.
0:24:48 > 0:24:51While the Red basket is filling up nicely,
0:24:51 > 0:24:55it looks like the nuclear box has got the better of the Yellows
0:24:55 > 0:24:58as they struggle on against the sea of gunge.
0:25:05 > 0:25:07SIRENS BLARE
0:25:07 > 0:25:09OK. That is it. Time's up. Stop.
0:25:09 > 0:25:12It's time to find out who's won so we'll count up the pods.
0:25:12 > 0:25:14Obviously I'm not going to do that myself
0:25:14 > 0:25:17because that goo would melt all my flesh off
0:25:17 > 0:25:18so I'll ask these lab rats.
0:25:18 > 0:25:20Lab rat, how many have the Yellow Team got?
0:25:20 > 0:25:22Three. Well done.
0:25:22 > 0:25:24Lab rat, how many for the Red Team?
0:25:24 > 0:25:27Five for the Reds. That means the Red Team are the winners!
0:25:30 > 0:25:33Sorry, Yellow Team. Let's find out exactly what the Red Team have won.
0:25:33 > 0:25:36For this I need my Ninja-trained Nan.
0:25:36 > 0:25:38Ninja will tell us what you've won.
0:25:38 > 0:25:41Each of you will be taking home an MP3 player,
0:25:41 > 0:25:43a slime test lab,
0:25:43 > 0:25:45a brain teaser jigsaw,
0:25:45 > 0:25:48a Blast Lab goody bag,
0:25:48 > 0:25:50and a lunar eclipse bedroom light.
0:25:50 > 0:25:54All those prizes for the Red Team. Taking them home. Well done.
0:25:54 > 0:25:57This bit is slightly more tricky, Yellow Team,
0:25:57 > 0:26:01because you WOULD have won and taken home all of these things.
0:26:01 > 0:26:03An adventure watch,
0:26:03 > 0:26:05a slime test lab,
0:26:05 > 0:26:10and finally, a lunar eclipse bedroom light, would have been yours.
0:26:10 > 0:26:13Sadly, though, you're going to have to blow them up
0:26:13 > 0:26:15because it is time for Bidet Goes Bang.
0:26:24 > 0:26:28Well, we are at that point in the show. Yellow Team, how you feeling?
0:26:28 > 0:26:32- Disappointed.- Yeah. Bad luck. What went wrong, do you think?
0:26:32 > 0:26:33We weren't fast enough.
0:26:33 > 0:26:36Yeah. Could have been faster, you'd have got more in.
0:26:36 > 0:26:38- It's difficult, isn't it?- Yeah.
0:26:38 > 0:26:41- Who's going to press the plunger, blow up the prizes?- All of us.
0:26:41 > 0:26:43Together, all of you? OK. Right.
0:26:43 > 0:26:46Well, Yellow Team, bad luck. Red Team, stop gloating.
0:26:46 > 0:26:49You're not saying anything but I can hear it. Congratulations though.
0:26:49 > 0:26:51You did well. You take all that home.
0:26:51 > 0:26:54You guys are gonna blow yours up, so please lift the plunger.
0:26:54 > 0:26:58No point putting it off. It would be unfair to let both teams
0:26:58 > 0:26:59go away with prizes.
0:26:59 > 0:27:02That's why, by law, we have to blow them up in a bidet.
0:27:02 > 0:27:05It happens on all game shows. That's just how it is.
0:27:05 > 0:27:07There's no putting it off any longer.
0:27:07 > 0:27:10Your prizes are in position. Are you ready to blow them up?
0:27:10 > 0:27:13Give you the countdown. Ready, everybody? 5...
0:27:13 > 0:27:154...3...
0:27:15 > 0:27:182...1...Go!
0:27:18 > 0:27:20BOOMING AND GURGLING
0:27:20 > 0:27:22Well, done, Yellows.
0:27:22 > 0:27:24Unfortunately, that's all we've got time for.
0:27:24 > 0:27:28Today, we have discovered how a build-up of pressure can be used
0:27:28 > 0:27:29to launch rockets and make chips.
0:27:29 > 0:27:32I'm thinking about combining the two
0:27:32 > 0:27:35and sending the first chips into space.
0:27:35 > 0:27:39But then I'd have to send salt into space...and vinegar...and ketchup.
0:27:39 > 0:27:41It's just getting too complicated.
0:27:41 > 0:27:43Let's just forget it. See you next time.
0:27:43 > 0:27:45CHEERING AND APPLAUSE
0:27:51 > 0:27:54Blast Lab was recorded before a live studio audience.
0:27:54 > 0:27:56No lab rat was harmed during the filming,
0:27:56 > 0:28:00but there are a couple that won't be at work next week.
