0:00:30 > 0:00:32CHEERING AND APPLAUSE
0:00:35 > 0:00:37Hello, hello.
0:00:37 > 0:00:39I'm Richard and this is Blast Lab,
0:00:39 > 0:00:41my top-secret underground science lab.
0:00:45 > 0:00:47Get my lab coat on.
0:00:47 > 0:00:48Got to be safe.
0:00:48 > 0:00:49Actually, very few people
0:00:49 > 0:00:53have stepped in to this high-security testing facility.
0:00:53 > 0:00:56And because some of my science experiments do go a bit wrong,
0:00:56 > 0:00:58even fewer people have ever stepped out.
0:00:58 > 0:01:02But don't worry! You'll be totally safe in here
0:01:02 > 0:01:05as long as you don't do not exactly what I don't say...to do.
0:01:05 > 0:01:08See? Can't be any clearer than that.
0:01:08 > 0:01:10In a second, you'll meet two teams
0:01:10 > 0:01:12who'll compete in scientific games to win prizes.
0:01:12 > 0:01:14So let's see what's in store today.
0:01:26 > 0:01:28CHEERING AND APPLAUSE
0:01:28 > 0:01:29Now, normally I have
0:01:29 > 0:01:33a highly-skilled team of SAS men protecting my lab.
0:01:33 > 0:01:36Unfortunately their highly-skilled SAS driver
0:01:36 > 0:01:39got lost on the way here so they're stuck in Skegness.
0:01:39 > 0:01:42However, I've been lucky enough to bring in at the last minute
0:01:42 > 0:01:45the only person who can beat the SAS in an arm wrestle.
0:01:45 > 0:01:47It is Ninja Nan.
0:01:47 > 0:01:49CHEERING AND APPLAUSE
0:01:57 > 0:01:58Ninja Nan!
0:01:58 > 0:02:00Thanks for standing in, Nan.
0:02:00 > 0:02:02THANKS FOR... Never mind.
0:02:02 > 0:02:05She might look fragile, but she is a fully trained ninja.
0:02:05 > 0:02:07Lethal.
0:02:09 > 0:02:13Um...Nan, if you'd like to take your place in security.
0:02:13 > 0:02:15If you'd like to move to... take your...
0:02:15 > 0:02:17TAKE YOUR PLACE IN SECURITY PLEASE, NAN.
0:02:17 > 0:02:21Thank you. Ah, she's deadly. Off she goes. Look at her move.
0:02:21 > 0:02:24Still moving. She moves so quickly, they named nanoseconds after her.
0:02:24 > 0:02:26Still moving.
0:02:26 > 0:02:30Nan, are you there yet?
0:02:30 > 0:02:33Is she in security? Oh, there's her little booth.
0:02:33 > 0:02:36She's making her way there. You can't hurry her or she'll get angry.
0:02:36 > 0:02:39She's in a chair, she's found a seat. That's a relief.
0:02:39 > 0:02:43Let's have a look at who's trying to get into the lab today.
0:02:43 > 0:02:44We can't be too careful.
0:02:44 > 0:02:47There's a bunch of people who claim to be the Yellow Team.
0:02:47 > 0:02:49CHEERING AND APPLAUSE
0:02:49 > 0:02:52OK, now, you've got to...
0:02:52 > 0:02:55Don't applaud yet, because we don't know...
0:02:55 > 0:02:59They claim to be the Yellow Team, you could be anybody.
0:02:59 > 0:03:00What are your names?
0:03:00 > 0:03:05- Aliyah!- Max!- Rosaline!- OK, that checks out with my security checks.
0:03:05 > 0:03:09It says here you have a hidden talent. All of you can sing.
0:03:09 > 0:03:11THEY ALL SING BADLY
0:03:13 > 0:03:16Good grief. Is that singing, everybody? What do you reckon?
0:03:16 > 0:03:18AUDIENCE: No!
0:03:18 > 0:03:20- They're not too sure in here... - Oh, come on!
0:03:20 > 0:03:24OK! Oh, come on - that does it. You are the yellow team. Come through.
0:03:24 > 0:03:26CHEERING AND APPLAUSE
0:03:26 > 0:03:29Max, Aliyah and Rosaline, welcome to the studio.
0:03:29 > 0:03:32Welcome to the Laboratory, it's lovely to see you.
0:03:32 > 0:03:35- Where are you all from?- Twickenham. - That's nice.
0:03:35 > 0:03:39- Anything else we should know about you?- ALL: We're the Cheeky Monkeys!
0:03:39 > 0:03:42- Is that a team name you've made up? - ALL: Yes!
0:03:42 > 0:03:44Well, you're the Yellow Team. Forget that.
0:03:44 > 0:03:47Thanks for coming in, nice to have you in the Laboratory.
0:03:47 > 0:03:50There should be people in there claiming to be the Red Team.
0:03:50 > 0:03:54Don't applaud yet, we don't know. They could be anybody
0:03:54 > 0:03:57trying to break into my top secret underground lab.
0:03:57 > 0:03:59Let's make sure they are who they say they are.
0:03:59 > 0:04:02The Red Team, I have your names here. What are they?
0:04:02 > 0:04:07- Ebony!- Sally!- Olivia!- Crikey, you're very cheery, aren't you?
0:04:07 > 0:04:10Ebony, Sally and Olivia - yes, that's right.
0:04:10 > 0:04:13You're hidden talent here, it says on my security form -
0:04:13 > 0:04:18Olivia, you can do a one-handed cartwheel? Can you?
0:04:18 > 0:04:20Oh, she's going to. Wow!
0:04:20 > 0:04:23OK, that's it. You must be the Red Team. Come on in, then!
0:04:23 > 0:04:26CHEERING AND APPLAUSE
0:04:28 > 0:04:33Sally, Ebony and Olivia, you are the Red Team. Where are you all from?
0:04:33 > 0:04:37ALL: We're The Atoms and we're from Northampton.
0:04:37 > 0:04:40- You're the what?- ALL: Atoms. - No, you're the Red Team.
0:04:40 > 0:04:43Right, it's time to move on. It's time to play round one.
0:04:43 > 0:04:46Teams, take your positions over there, please.
0:04:46 > 0:04:49Now, they do say in relationships that looks don't matter.
0:04:49 > 0:04:52Well, here's the proof, it's Oliver.
0:05:07 > 0:05:10APPLAUSE AND CHEERING
0:05:10 > 0:05:14Now, Oliver loves nothing more than collecting fact on his travels
0:05:14 > 0:05:16for his Fact Nav system.
0:05:16 > 0:05:19Trouble is, not all of his fact turns out to be true.
0:05:19 > 0:05:24It's up to both the teams to decide what is true or false in Fact Nav.
0:05:24 > 0:05:25So this is how it's going to work.
0:05:25 > 0:05:28I'm going to read both teams a science fact.
0:05:28 > 0:05:32You then have to tell me whether that fact is true or false.
0:05:32 > 0:05:37OK? If it's true, Oliver will let us know by doing this...
0:05:37 > 0:05:40HORN TOOTS AND SIRENS BLARE
0:05:40 > 0:05:44And if it's false, he'll use his horn like this...
0:05:44 > 0:05:47DEEP FOGHORN
0:05:47 > 0:05:49He's quite noisy, Oliver, as it turns out.
0:05:49 > 0:05:53We ready? We understand the rules? OK, Red Team, you're going first.
0:05:53 > 0:05:55This is your question.
0:05:55 > 0:05:58You have to tell me whether this fact is true or false.
0:05:58 > 0:06:01An object can be thrown further if it is thrown west.
0:06:01 > 0:06:03Don't answer straight away.
0:06:03 > 0:06:06You can talk amongst yourselves and have a think.
0:06:06 > 0:06:08Audience, what do you think?
0:06:08 > 0:06:11AUDIENCE: False!
0:06:11 > 0:06:15- False.- True!- Oh, hang on. Nearly everybody thinks it's false.
0:06:15 > 0:06:19You don't have to go with what the audience think.
0:06:19 > 0:06:22Think it out for yourselves. But the rest of us all think, "False."
0:06:22 > 0:06:26All right, then. Well, let's find out what our team thinks.
0:06:26 > 0:06:29I shall put my combined mug tree and microphone back, nobody liked it.
0:06:29 > 0:06:32Right, what do we think? What's your answer?
0:06:32 > 0:06:35- False.- You think it's false?
0:06:35 > 0:06:38You think an object can't be thrown further if it's thrown west.
0:06:38 > 0:06:40Oliver, is it true or false?
0:06:40 > 0:06:42HORN TOOTS AND SIRENS BLARE
0:06:42 > 0:06:45It's true. Which means, sorry guys, you're wrong.
0:06:45 > 0:06:48It's actually because the Earth rotates towards the east.
0:06:48 > 0:06:52If you stand on the equator, you can be travelling at over 1,000 mph
0:06:52 > 0:06:56without feeling like you're moving, cos the Earth rotates.
0:06:56 > 0:06:59Right now, where we are, we're travelling at over 600 mph.
0:06:59 > 0:07:01And it's not even ruffling my hair.
0:07:01 > 0:07:04Yellow Team, here comes your science fact.
0:07:04 > 0:07:06Tell me if this is true or false. Are you ready?
0:07:06 > 0:07:10When the sun rises over Uranus's North Pole,
0:07:10 > 0:07:13that's the planet Uranus, the North Pole,
0:07:13 > 0:07:14it stays light there
0:07:14 > 0:07:15for a whole month.
0:07:15 > 0:07:17So when the sun rises,
0:07:17 > 0:07:20the start of a day here, at Uranus,
0:07:20 > 0:07:23it stays light for a whole month. Is that true or false?
0:07:23 > 0:07:27Have a think, don't answer straight away. Audience, what do we think?
0:07:27 > 0:07:30Is that true or false? Stays light for a whole month.
0:07:30 > 0:07:32AUDIENCE SHOUTS OUT
0:07:32 > 0:07:34Quite a lot of trues.
0:07:34 > 0:07:37Team? Do you think it's true or false?
0:07:37 > 0:07:40- We've gone with true. - You've gone with true,
0:07:40 > 0:07:43- you think it does stay light for a whole month.- Yes.
0:07:43 > 0:07:44OK. All right.
0:07:44 > 0:07:47Oliver, is it true or false?
0:07:47 > 0:07:49DEEP FOGHORN
0:07:49 > 0:07:51Bad luck, Yellows, it's actually false.
0:07:51 > 0:07:55I can tell you the real answer. It stays light, so the sun comes up
0:07:55 > 0:07:59over the North Pole and it stays light for 42 years.
0:07:59 > 0:08:02Yeah, yeah.
0:08:02 > 0:08:05If the sun was to rise there now, you'd be 50 when it got dark again.
0:08:05 > 0:08:07I'd be, you know, 55, maybe 60.
0:08:07 > 0:08:09TITTERING
0:08:09 > 0:08:13Thank you, lab rats. OK, there's one last chance for you to get a point.
0:08:13 > 0:08:17It's time for your third question. This one works differently, though.
0:08:17 > 0:08:19LOUD CRASH
0:08:19 > 0:08:23Oh, that sounds bad. Lab rats! Please, guys...
0:08:23 > 0:08:27They've been experimenting all night trying to make a telephone
0:08:27 > 0:08:33to improve our mobile phones with a two shoes and a bit of string.
0:08:33 > 0:08:36It doesn't work and it won't work. You can't make a phone out of shoes.
0:08:36 > 0:08:40You can send e-mails with socks, but you can't phone with shoes.
0:08:40 > 0:08:44Go and do something useful, or it'll be back in the cage. Go.
0:08:44 > 0:08:46Find something useful to do. Right.
0:08:46 > 0:08:48I'm gonna ask you a question and this time
0:08:48 > 0:08:51you don't have to tell me if it's true or false.
0:08:51 > 0:08:55You have to write down what you think the answer might be.
0:08:55 > 0:08:57You've got a pad in front of you to write on, OK?
0:08:57 > 0:09:01Then you'll show us the answer. You may not be exactly right
0:09:01 > 0:09:04but the team that gets closest will get the point.
0:09:04 > 0:09:06Here is your question.
0:09:06 > 0:09:11What was the hottest temperature ever recorded on Earth?
0:09:11 > 0:09:14I'd like the answer in degrees Celsius, please.
0:09:14 > 0:09:16You're allowed to have a little bit of a think.
0:09:16 > 0:09:20Does anybody in the audience have any idea what it might be?
0:09:20 > 0:09:23Hands going up. Hang on, where's my mug tree mic?
0:09:23 > 0:09:26- Yes? What do you think it might be? - I think it might be 58.
0:09:26 > 0:09:29- Right, what do you think? - I think it's around 56.
0:09:29 > 0:09:33- OK, anybody think higher than that? - 58?- OK. All right then, guys.
0:09:33 > 0:09:37OK, reveal your answers for us, please. Let's have a look.
0:09:37 > 0:09:41Reds, you've gone with 60. Yellows, you've gone with 50.
0:09:41 > 0:09:43The actual answer is...
0:09:43 > 0:09:47One of our audience members is very clever. It is 58 degrees Celsius.
0:09:47 > 0:09:51It was recorded at the El Azizia weather station in Libya in 1922,
0:09:51 > 0:09:54so Reds, you get the point. Well done, Reds!
0:09:54 > 0:09:57CHEERING AND APPLAUSE
0:10:10 > 0:10:11CHEERING AND APPLAUSE
0:10:11 > 0:10:15That's to come. Now, though, it's time for Mini Science.
0:10:15 > 0:10:17Our contestants get to test their brains
0:10:17 > 0:10:20and get all sciencey with some everyday household objects.
0:10:20 > 0:10:23To help me is my old science teacher, Mini Miss.
0:10:27 > 0:10:28- Hello, Richard.- Hello.
0:10:28 > 0:10:30CHEERING AND APPLAUSE
0:10:30 > 0:10:34Let me just explain something. When I made one of my inventions -
0:10:34 > 0:10:37it's very important to write an instruction manual,
0:10:37 > 0:10:39cos otherwise I forget how it works.
0:10:39 > 0:10:41Unfortunately, I forgot where I put the manual.
0:10:41 > 0:10:44When I tried my new time machine out, I made a few little mistakes.
0:10:44 > 0:10:47I set the controls to bring back my old science teacher,
0:10:47 > 0:10:50but didn't realise she'd come back as a ten-year-old.
0:10:50 > 0:10:55- Thanks, Richard.- Sorry. You know your science, though.- Of course!
0:10:55 > 0:10:57I'm a professor in nuclear physics
0:10:57 > 0:10:59and I've been teaching for over 40 years.
0:10:59 > 0:11:02See? So what have you got for us this time, Miss?
0:11:02 > 0:11:06Today's teams are going to be playing Cup On Your Face.
0:11:06 > 0:11:09All you need are these cups. The teams then have to stick
0:11:09 > 0:11:12as many of these cups onto their face as possible
0:11:12 > 0:11:16and at the end of the course, have to drop the cups into a cylinder.
0:11:16 > 0:11:19The teams with the most amount of cups in the cylinder
0:11:19 > 0:11:21at the end of the game wins.
0:11:21 > 0:11:23I see. So, Cup On Your Face.
0:11:23 > 0:11:26I'm just thinking about the science here, Miss.
0:11:26 > 0:11:28I reckon this is about pressure, isn't it?
0:11:28 > 0:11:31Because when you squeeze the cup like that,
0:11:31 > 0:11:33it squeezes some of the air out.
0:11:33 > 0:11:35Then when you put it on your face,
0:11:35 > 0:11:37the cup goes back to its original shape,
0:11:37 > 0:11:40so there's not as much air in that space as there is outside.
0:11:40 > 0:11:44That means lower pressure and that means it's stuck on your face.
0:11:44 > 0:11:47- Correct!- I was listening back then. I'm gonna demo the course.
0:11:47 > 0:11:48Here's what you do.
0:11:48 > 0:11:51First of all, you cross the Bridge Of Destiny
0:11:51 > 0:11:54over the nuclear tank. Do not fall in, it's just terrible.
0:11:54 > 0:11:57Down the steps, keeping to the left of this line.
0:11:57 > 0:12:00If the cups fall off your face at any point,
0:12:00 > 0:12:02don't stop, keep going and finish.
0:12:02 > 0:12:04Past the lab rats... Idiot.
0:12:04 > 0:12:06Then you get round here to the high jump.
0:12:06 > 0:12:09You go underneath with the cups still on your face.
0:12:09 > 0:12:11Over my attempt at reinventing the bicycle.
0:12:11 > 0:12:15Then you have the stepping stones of science. Whatever route you like.
0:12:15 > 0:12:18You get to the finish. If you've got any cups left on your face,
0:12:18 > 0:12:20take 'em off, drop 'em into the canister.
0:12:20 > 0:12:24Then, you return. Same route, across the bridge on the left-hand side.
0:12:24 > 0:12:29The next player will have got ready with your cups, ready to leave.
0:12:29 > 0:12:33But you don't just run away when the other person gets back.
0:12:33 > 0:12:36You have to high-five in an annoying way. Well done.
0:12:36 > 0:12:38So that's it. Everybody understand?
0:12:38 > 0:12:41You get the rules? As many as you can do.
0:12:41 > 0:12:43You've got some time to do this.
0:12:43 > 0:12:47And that some time starts...now.
0:12:47 > 0:12:51So, first thing's first, the cups have to go on the face.
0:12:51 > 0:12:55It'll be interesting to see how many cups they go for.
0:12:55 > 0:12:59Reds going for two, but the Yellows have made a quicker start.
0:12:59 > 0:13:02That's because Max has only one cup on his face.
0:13:06 > 0:13:08Oh, and a dropped cup for the Reds.
0:13:10 > 0:13:13But in it goes, so one cup each at this point.
0:13:14 > 0:13:16Both teams playing it safe to start.
0:13:16 > 0:13:21Only going for one or two cups. You can put as many as you like on.
0:13:21 > 0:13:24But they might all fall off.
0:13:24 > 0:13:26Look, the Reds bag another one.
0:13:26 > 0:13:31Aliyah has to go back having lost her cups on the way round.
0:13:34 > 0:13:38Oh, and Rosaline has lost one. Funny thing, suction.
0:13:38 > 0:13:41People often think suction is about things being pulled,
0:13:41 > 0:13:44but it's the opposite. Because there are fewer air molecules
0:13:44 > 0:13:46in the cup than there are outside,
0:13:46 > 0:13:49the air outside is pushing it onto your face.
0:13:49 > 0:13:50That's how suction works.
0:13:55 > 0:13:59Ebony back with a changeover now and look at that!
0:13:59 > 0:14:02Yellow very confident with two, there.
0:14:04 > 0:14:08Three from Red. Look at that. That's magnificent!
0:14:08 > 0:14:09Oh, well one's gone.
0:14:13 > 0:14:15A brave try, there. Multiple cups.
0:14:18 > 0:14:21Olivia going with three cups as well.
0:14:21 > 0:14:25If she can get the round the course, that could win the Reds the game.
0:14:30 > 0:14:34That's it, time's up! That was close. One last one going in.
0:14:34 > 0:14:36Well done!
0:14:36 > 0:14:38OK. This is it - moment of truth.
0:14:38 > 0:14:42Let's have a look, see who's collected the most cups.
0:14:42 > 0:14:45I shall tip them out. For the Reds - seven.
0:14:45 > 0:14:49Will you remember seven? Cos I'll forget when I've counted these.
0:14:49 > 0:14:54For the Yellows - one, two, three, four, five, six.
0:14:54 > 0:14:59What I don't understand is, there are two reds in here.
0:14:59 > 0:15:01Yellow Team?
0:15:01 > 0:15:04Yellow Team? How did that happen?
0:15:04 > 0:15:09- You put them in the wrong one? - Yeah, she put them in the wrong one.
0:15:09 > 0:15:12Look at your jacket. What colour is it, Ebony?
0:15:12 > 0:15:17- Red.- What colour are they wearing?- Yellow.
0:15:17 > 0:15:19- And what colour's this?- Yellow.
0:15:19 > 0:15:23I'm sorry. As a lab rat, you can't have those points.
0:15:23 > 0:15:27However, still with seven to four,
0:15:27 > 0:15:31the Red Team wins anyway!
0:15:31 > 0:15:33CHEERING AND APPLAUSE
0:15:36 > 0:15:38So, if that works for cups on faces,
0:15:38 > 0:15:43how much suction can we get if we make the cup a bit bigger?
0:15:45 > 0:15:50So just how strong is this air pressure?
0:15:50 > 0:15:53My faithful lab rats are gonna find out.
0:15:53 > 0:15:55These are Magdeburg pressure spheres.
0:15:55 > 0:15:59Yeah, I don't know what they are either. But Phil Collins does.
0:15:59 > 0:16:03MUSIC: "In The Air Tonight" by Phil Collins
0:16:08 > 0:16:09No, he's not the 1980's pop star
0:16:09 > 0:16:12your dad makes you listen to in the car.
0:16:12 > 0:16:14Hi, I'm Phil Collins, the vacuum expert.
0:16:14 > 0:16:15Of course you are.
0:16:15 > 0:16:19This Phil Collins knows all about air pressure.
0:16:19 > 0:16:22To see how they work, we first need to join them together
0:16:22 > 0:16:24and suck all the air out.
0:16:24 > 0:16:28One of the lab rats gives it a go, but as usual, it's a rubbish effort.
0:16:28 > 0:16:31Thankfully, Phil Collins has brought a vacuum pump.
0:16:31 > 0:16:35By sucking the air out of the sphere,
0:16:35 > 0:16:37the air pressure inside the sphere is lowered,
0:16:37 > 0:16:41allowing the air pressure on the outside to push with its full force.
0:16:41 > 0:16:44That's the weight of five gorillas.
0:16:46 > 0:16:49Let's see if our weedy lab rats can pull them apart.
0:16:53 > 0:16:55Oh, dear. Just look at these two.
0:16:55 > 0:16:59They said they were the best lab rats for the job.
0:16:59 > 0:17:01But as I thought - pathetic.
0:17:03 > 0:17:07Time for some proper muscle, like this international body builder,
0:17:07 > 0:17:09called Tina.
0:17:09 > 0:17:12One strong woman and two lab rats.
0:17:12 > 0:17:15This should be as easy as opening a bag of crisps.
0:17:15 > 0:17:17WHISTLE BLOWS
0:17:21 > 0:17:24Obviously a very stubborn bag of crisps.
0:17:25 > 0:17:28Come on Phil, be a gent. Give the lady a hand.
0:17:28 > 0:17:30WHISTLE BLOWS
0:17:30 > 0:17:32At last.
0:17:32 > 0:17:35But Phil Collins has one more sphere up his sleeve.
0:17:35 > 0:17:37And it's a biggie.
0:17:37 > 0:17:41A bigger sphere should take even more grunt to pull apart.
0:17:43 > 0:17:45WHISTLE BLOWS
0:17:45 > 0:17:48Phil Collins has stumped the lab rats
0:17:48 > 0:17:50and strong woman, Tina, this time.
0:17:50 > 0:17:54Well, they can barely lift it off the ground let alone pull it apart.
0:17:54 > 0:17:59We need something with more power, more grip and an engine.
0:17:59 > 0:18:04We've got two Land Rovers to settle this one once and for all.
0:18:04 > 0:18:07Let's hold the film there, cos Red Team I want to ask you,
0:18:07 > 0:18:10for an extra point, do you reckon the car's gonna do it?
0:18:10 > 0:18:14- Yeah.- You think they can? OK. Yellows?
0:18:14 > 0:18:18Can they pull the spheres apart? Held together by a vacuum.
0:18:18 > 0:18:21All the air taken out. Sucked together.
0:18:21 > 0:18:25Well, basically, they could reverse and then go really fast.
0:18:25 > 0:18:30- So, do you think they might do it? - Yeah.- I don't think so, though.
0:18:30 > 0:18:33Right, so you better decide as a team.
0:18:33 > 0:18:35While you're deciding, I'm gonna ask the audience
0:18:35 > 0:18:37with my amazing mug tree microphone.
0:18:37 > 0:18:39What do you reckon guys, can they do it?
0:18:39 > 0:18:42- I think they can do it. - You think they can.
0:18:42 > 0:18:44- I think they can. - I think they can't.
0:18:44 > 0:18:47You think they can't? Remember, they're not glued together.
0:18:47 > 0:18:50They're only held together by suction.
0:18:50 > 0:18:53- Um...I still think they can't do it.- OK.
0:18:53 > 0:18:56Right, I'm gonna find out now. Yellow Team, make your minds up.
0:18:56 > 0:18:58- Can they or can't they?- Can.- Can.
0:18:58 > 0:19:02Both teams think they can. Let's have a look for an extra point each.
0:19:04 > 0:19:06So, let's get this straight.
0:19:06 > 0:19:10With the air removed, the sphere is being pushed together with the force
0:19:10 > 0:19:11of over five gorillas.
0:19:11 > 0:19:14And we're trying to pull it apart with two Land Rovers.
0:19:14 > 0:19:17Who will win this tug of war tussle?
0:19:17 > 0:19:19Gorilla or Land Rover?
0:19:19 > 0:19:23ENGINES REV
0:19:32 > 0:19:35We've added a pressure gauge to keep an eye on
0:19:35 > 0:19:39how much force the Land Rovers are pulling with.
0:19:39 > 0:19:41Well, come on, boys - floor it!
0:19:45 > 0:19:47That's unbelievable.
0:19:47 > 0:19:50It's just the pressure of air holding that sphere together.
0:19:50 > 0:19:53Surely it's got to give in at some point.
0:19:53 > 0:19:55Even the gauge has given up.
0:20:01 > 0:20:03Hey, there she goes!
0:20:11 > 0:20:16It's taken two Land Rovers at full power to pull the sphere apart.
0:20:16 > 0:20:19That's how strong air pressure is.
0:20:21 > 0:20:24OK, you can stop now, fellas.
0:20:24 > 0:20:27They did it. That means there's one point each for both teams.
0:20:27 > 0:20:29Round of applause for both Yellows and Reds.
0:20:29 > 0:20:31Well done.
0:20:34 > 0:20:37So that means, Red Team, you're ahead with three points,
0:20:37 > 0:20:41Yellow, you have one. Both teams, it's time to go and get changed
0:20:41 > 0:20:44into your protective suits for the Messy Messy Mess Test.
0:20:44 > 0:20:46You're gonna need them.
0:20:46 > 0:20:48It is essential for scientists to keep a level head.
0:20:48 > 0:20:51Now, I dunno about you, but watching that film,
0:20:51 > 0:20:53I thought those two lab rats
0:20:53 > 0:20:55were having too much fun driving those cars.
0:20:55 > 0:20:57So to keep their feet on the ground,
0:20:57 > 0:21:00I've asked them to sort out Ninja Nan's feet.
0:21:00 > 0:21:03So, they're doing that now in the security room. There you go.
0:21:03 > 0:21:04Good luck, guys!
0:21:04 > 0:21:07A shame you didn't have the protective suits on.
0:21:07 > 0:21:10- Get on with it.- AUDIENCE: Eugh! - I know it's nasty,
0:21:10 > 0:21:12but it's good for them. They have to learn.
0:21:12 > 0:21:14We move on to our final game.
0:21:14 > 0:21:16Today's Messy Messy Mess Test is in the nuclear box...
0:21:20 > 0:21:24..which is why you guys all needed the protective outfits on, OK?
0:21:24 > 0:21:27Just be very careful in there. It's...horrible.
0:21:27 > 0:21:30Actually, a whole family of diseased pigeons
0:21:30 > 0:21:33flew into this yesterday and decided to make it their home.
0:21:33 > 0:21:35They may have all gone, I don't know.
0:21:35 > 0:21:38No, look, they've grown gills.
0:21:38 > 0:21:41Don't stroke anything there, everything's got teeth.
0:21:41 > 0:21:45Right, this is the game. Each of these pods contains fabulous prizes,
0:21:45 > 0:21:47like a solar-powered spider, an Mp3 player,
0:21:47 > 0:21:51a kitchen chemistry set... The idea is to move these prize pods
0:21:51 > 0:21:54from this end of the nuclear box to the other end.
0:21:54 > 0:21:57Obviously, you can't use your hands because they'd melt off,
0:21:57 > 0:21:59it'd be horrible, which is why
0:21:59 > 0:22:02you've got these tongs to use, instead. Very nicely demonstrated.
0:22:02 > 0:22:05The team to move the most prize pods to the other end
0:22:05 > 0:22:09and then put them in the basket wins and gets to take them home.
0:22:09 > 0:22:13The losing team blows them up.
0:22:13 > 0:22:16That's what happens, OK? You don't take them home, you blow them up.
0:22:16 > 0:22:20Red Team, you are gonna start first because you have the most points,
0:22:20 > 0:22:22which means you get a five second advantage.
0:22:22 > 0:22:24Yellow Team, you start second.
0:22:24 > 0:22:27So, when you hear the first nuclear alert, Red Team starts.
0:22:27 > 0:22:29When you hear the second, Yellow starts.
0:22:29 > 0:22:33Everybody understand? No using your hands, only using these.
0:22:33 > 0:22:35You have some time to get as many prize pods
0:22:35 > 0:22:38as you can from this end to the other end of the nuclear box
0:22:38 > 0:22:41and that time starts, for the Red Team, now!
0:22:41 > 0:22:43SIREN BLARES
0:22:43 > 0:22:45Away we go with the Reds.
0:22:45 > 0:22:49It's Ebony who has to pluck a prize pod from the awful toxic gunge.
0:22:49 > 0:22:52Scientifically, what's difficult here is...
0:22:52 > 0:22:56well, it's friction. You just can't get any grip on the prize pods
0:22:56 > 0:22:59and they fall out. They're struggling.
0:23:01 > 0:23:04The Reds have got a pod to the second changeover.
0:23:04 > 0:23:06This is the crucial point. And...
0:23:06 > 0:23:09yes, they've done it! Well done, Reds!
0:23:09 > 0:23:11Well done, Reds. One.
0:23:11 > 0:23:16The Yellows, on the other hand, are still on the first tricky handover.
0:23:18 > 0:23:20Yellow have got a great technique going.
0:23:20 > 0:23:23Carefully passing it vertically from one to another.
0:23:23 > 0:23:28And that technique pays off. Bosh - one for the yellows!
0:23:28 > 0:23:33Oh, but hang on. Back come the Reds for their second pod in the basket.
0:23:33 > 0:23:37Oh, the Yellows drop one at the first changeover.
0:23:37 > 0:23:39That pod is now out of play.
0:23:43 > 0:23:47The Reds, however, are taking care of business
0:23:47 > 0:23:49in their side of the tank.
0:23:51 > 0:23:54And wallop - three in the prize basket for them.
0:23:55 > 0:23:58And...oh, another prize pod slips away from the yellows.
0:24:01 > 0:24:03Meanwhile, Reds are looking good.
0:24:04 > 0:24:06Oh, dear.
0:24:06 > 0:24:10The teams are gonna have to be quick, because sometimes,
0:24:10 > 0:24:12some time is over quicker than you think.
0:24:12 > 0:24:14But only sometimes.
0:24:18 > 0:24:19Time is coming to an end.
0:24:20 > 0:24:22SIREN BLARES
0:24:22 > 0:24:25That's it, time is up!
0:24:25 > 0:24:28Time is up. Well done, both teams. Now we'll find out who's won.
0:24:28 > 0:24:31Obviously, I can't possibly handle these prize pods
0:24:31 > 0:24:34because my hands would melt, so I've used lab rats
0:24:34 > 0:24:36because they're cheap and disposable.
0:24:36 > 0:24:39Yellows have got? One. Look at his paw in his little washing up glove.
0:24:39 > 0:24:41Red Team have got how many?
0:24:41 > 0:24:45Three. OK, that means Red Team are the winners! Well done!
0:24:45 > 0:24:48CHEERING AND APPLAUSE
0:24:50 > 0:24:54Now we're gonna find out exactly what the Red Team have won
0:24:54 > 0:24:57and to do that, I need my specially trained Ninja assistant here,
0:24:57 > 0:25:01Ninja Nan. Hello, Nan. She's got a wheelbarrow full of prizes.
0:25:01 > 0:25:03Nan, I'd like you to model the prizes...
0:25:03 > 0:25:05HE GASPS
0:25:05 > 0:25:07.. as we find out what they've won.
0:25:07 > 0:25:09If you could open the pods for me please, lab rat.
0:25:09 > 0:25:12What have they got? Each of you wins an Mp3 player,
0:25:12 > 0:25:14that's one of those each.
0:25:14 > 0:25:17You've also got a Test Tube Seahorse...
0:25:19 > 0:25:22..and a Flipout Surprise Egg. Well done, those are your prizes.
0:25:22 > 0:25:24CHEERING AND APPLAUSE
0:25:24 > 0:25:28Now the slightly painful bit, Yellow Team.
0:25:28 > 0:25:31This is where we find out what you would have won.
0:25:31 > 0:25:33You would each have got a Test Tube Seahorse.
0:25:33 > 0:25:37Instead of taking that home, you're gonna blow it up!
0:25:37 > 0:25:38Time for Bidet Goes Bang.
0:25:46 > 0:25:51- Well, this is it, Yellow Team. How are you feeling?- Sad.
0:25:51 > 0:25:54Well, never mind - you had fun playing the game.
0:25:54 > 0:25:56- Who's pressing the plunger? - All of us.
0:25:56 > 0:26:00Look at that, teamwork. Lovely. What do you think went wrong?
0:26:00 > 0:26:04Well, I think I couldn't pick up the pods at the beginning.
0:26:04 > 0:26:06I was trying to work out how to pick them up...
0:26:06 > 0:26:09- Are you taking the blame?- Yeah. - Wow! That's noble.
0:26:09 > 0:26:12That's teamwork from the Yellow Team.
0:26:12 > 0:26:14- Red Team, you're feeling fine, aren't you?- ALL: Yes!
0:26:14 > 0:26:16Loaded down with prizes.
0:26:16 > 0:26:19And we're about to watch the Yellow Team blow theirs up.
0:26:19 > 0:26:21OK, well, I spend a lot of my time here in my Blast Lab
0:26:21 > 0:26:24trying to work out the best way to blow things up.
0:26:24 > 0:26:27I tried blowing them up in a bath tub, in a toilet, in a shower,
0:26:27 > 0:26:29I've tried everything but the kitchen sink.
0:26:29 > 0:26:32Ninja Nan was using it. I didn't want to get into a fight.
0:26:32 > 0:26:36It turns out, the best way to obliterate something is in a bidet.
0:26:36 > 0:26:39It's over there. Your prizes are already in and ready to go bang.
0:26:39 > 0:26:42So I think this is it, we can't put it off any longer.
0:26:42 > 0:26:45Step forwards and lift the plunger, please, Yellow Team.
0:26:45 > 0:26:48Do not put it down yet, cos we'll do the countdown. Are we ready?
0:26:48 > 0:26:53'Five, four, three, two, one.'
0:26:54 > 0:26:57LARGE EXPLOSION
0:27:00 > 0:27:03Sorry, Yellow Team. Bad luck. Well done, Red Team, though.
0:27:03 > 0:27:05Time to bring today's show to an end.
0:27:05 > 0:27:08Today we played tug of war with Land Rovers,
0:27:08 > 0:27:10we've had lots of fun sticking cups on our faces,
0:27:10 > 0:27:12all because of air pressure.
0:27:12 > 0:27:14We shouldn't be confused with when people tell me
0:27:14 > 0:27:17to change my hair cut. That's called hair pressure.
0:27:17 > 0:27:19See you soon. Well done.
0:27:26 > 0:27:29Blast Lab was recorded before a live studio audience.
0:27:29 > 0:27:32No lab rat was harmed during the filming.
0:27:32 > 0:27:35Although some of them are still missing.
