0:00:34 > 0:00:35CHEERING AND APPLAUSE
0:00:36 > 0:00:39Hello, I'm Richard.
0:00:39 > 0:00:42Welcome to my top-secret underground laboratory
0:00:42 > 0:00:44where I do all my top-secret science.
0:00:51 > 0:00:52Nice to see you.
0:00:52 > 0:00:55Just one thing, though. I know this is my lab,
0:00:55 > 0:00:57but please don't call me a mad professor.
0:00:57 > 0:01:00It's not fair, cos technically I'm not a professor,
0:01:00 > 0:01:01so you can't say it.
0:01:01 > 0:01:03I should warn you, though, this lab is full
0:01:03 > 0:01:05of some pretty strange sounds and unusual smells...
0:01:05 > 0:01:08not all of them from this lot! But it's lovely to see you.
0:01:08 > 0:01:10Welcome to the lab.
0:01:12 > 0:01:15Very shortly, you'll be meeting two teams
0:01:15 > 0:01:18who think they can push the boundaries of science's envelope,
0:01:18 > 0:01:21to look at them, you'd think they'd have trouble opening an envelope.
0:01:21 > 0:01:24They'll be competing in scientific games
0:01:24 > 0:01:27and attempting to win prizes, so let's see what's in store today.
0:01:40 > 0:01:42Now, the work that goes on in this lab,
0:01:42 > 0:01:46everything that happens here is incredibly important.
0:01:46 > 0:01:48So important, in fact, that I have my own
0:01:48 > 0:01:51round-the-clock, 24-hour SAS protection team.
0:01:51 > 0:01:54Yeah, to look after me. Unfortunately, though,
0:01:54 > 0:01:57one of the SAS guys nicked his thumb on a tin of beans last night.
0:01:57 > 0:02:00It was really sore, so all the other guys have gone round to his house
0:02:00 > 0:02:02to comfort him, so they're not here.
0:02:02 > 0:02:07Instead, though, I've had to enlist the help of someone very special
0:02:07 > 0:02:10to ensure our round-the-clock safety - my nan.
0:02:10 > 0:02:13Don't mess with her, though, because she's a Ninja!
0:02:13 > 0:02:15CHEERING AND APPLAUSE
0:02:23 > 0:02:25Nan, hello.
0:02:25 > 0:02:27Thanks for standing in.
0:02:27 > 0:02:28I know she may look frail,
0:02:28 > 0:02:31but actually she's a fully-trained Ninja.
0:02:33 > 0:02:37OK, OK, Nan. Calm down. Nan, if you'd like to take your place.
0:02:37 > 0:02:38Nan? NAN! Thank you.
0:02:38 > 0:02:41If you'd like to take your place in the security office, thank you.
0:02:41 > 0:02:44It's best not to move too suddenly. She'll tear you apart.
0:02:44 > 0:02:47Honestly, I once saw her go off for a gentle jog
0:02:47 > 0:02:50and she set off a speed camera. Oh, yeah.
0:02:50 > 0:02:52You should see her house. It's spotless.
0:02:52 > 0:02:55There's no mess, no bugs. She doesn't even use fly spray.
0:02:55 > 0:02:59She's so quick, she catches them with chopsticks, like that. Deadly.
0:02:59 > 0:03:01Oh, yeah. She's nearly there.
0:03:01 > 0:03:03Nan, are you settled in yet?
0:03:03 > 0:03:05Have you taken a seat?
0:03:05 > 0:03:08She's...done it!
0:03:08 > 0:03:10No, no, no! Listen.
0:03:10 > 0:03:12You don't clap a fully-trained Ninja
0:03:12 > 0:03:16just for sitting down on an office chair, all right? She's serious.
0:03:16 > 0:03:19Let's have a look at who's trying to get into my lab today.
0:03:19 > 0:03:21Somewhere, there should be some people
0:03:21 > 0:03:22who claim to be the Yellow Team.
0:03:22 > 0:03:24CHEERING AND APPLAUSE
0:03:26 > 0:03:28Hello, so-called Yellow Team.
0:03:28 > 0:03:31I've got some facts here in my security file
0:03:31 > 0:03:33just to check you out before we let you in the lab.
0:03:33 > 0:03:37Can't let just anybody in here, OK? So identify yourselves, please.
0:03:37 > 0:03:40- I'm Leanna.- Darcy.- Daisy.
0:03:40 > 0:03:42Leanna, Darcy and Daisy. Yeah, that checks out.
0:03:42 > 0:03:44It says, "The hidden talent in your team
0:03:44 > 0:03:47is that one of you can do Irish dancing." Who can do that?
0:03:47 > 0:03:49- Me.- Leanna, you'll have to do that
0:03:49 > 0:03:52to prove that you are who you say you are.
0:03:54 > 0:03:56Well, yeah, I'd say that was Irish dancing.
0:03:56 > 0:03:58I'm no expert but that...
0:03:58 > 0:04:00Was that Irish dancing? Yeah, that was Irish dancing.
0:04:00 > 0:04:03That proves that you're the Yellow Team.
0:04:03 > 0:04:05Come into the lab, please. You're through security.
0:04:08 > 0:04:11Hello, Yellow Team. Lovely to see you all.
0:04:11 > 0:04:13Where are you all from, by the way?
0:04:13 > 0:04:17ALL: Hertfordshire! And we're the Smarty Pants!
0:04:17 > 0:04:19You've given yourselves a name?
0:04:19 > 0:04:21- Yeah.- Wrong. You're the Yellow Team OK,
0:04:21 > 0:04:24but welcome to the laboratory. Don't touch anything.
0:04:24 > 0:04:27Stay there, because we've got to meet your opponents.
0:04:27 > 0:04:28Somewhere, a bunch of people
0:04:28 > 0:04:31who think they're the Red Team. Where are you?
0:04:34 > 0:04:37The same for you guys. Before I can let you past
0:04:37 > 0:04:40Ninja Nan on security, I've got to check you are who you say you are.
0:04:40 > 0:04:42- What are your names?- Joe. - Max.- And Daniel.
0:04:42 > 0:04:45Joe, Max and Daniel. That checks out. Hidden talent.
0:04:45 > 0:04:48In my security file, it says, Max - if you are Max -
0:04:48 > 0:04:51you can touch your nose with your tongue.
0:04:51 > 0:04:52Go on, then.
0:04:53 > 0:04:56Oh, you can. You did. Give him a round of applause.
0:04:56 > 0:04:57You are the Red Team. Come on in.
0:05:02 > 0:05:04OK, that is you. You are through security.
0:05:04 > 0:05:05Where are you all from?
0:05:05 > 0:05:07- We're from Oxfordshire...- Nice.
0:05:07 > 0:05:10- ..and we're...- Flash.- Bang. - Wallop.- No, you're not.
0:05:10 > 0:05:13You're the Red Team, and that's final. Welcome to the laboratory.
0:05:13 > 0:05:17Great to have you here. I think it's time to play Round One so,
0:05:17 > 0:05:19teams, take your positions, please.
0:05:19 > 0:05:22And while they do that, I've got a very special assistant to help me.
0:05:22 > 0:05:24He is Oliver.
0:05:41 > 0:05:43We've been across Africa together
0:05:43 > 0:05:46and now he is here with us in the laboratory.
0:05:46 > 0:05:49He's been given a make-over specially for his new job,
0:05:49 > 0:05:50and I've actually fitted him
0:05:50 > 0:05:53with an artificially intelligent computer system.
0:05:53 > 0:05:56Actually, Oliver is very environmentally-friendly.
0:05:56 > 0:05:59He runs on nothing but Girls Aloud CDs,
0:05:59 > 0:06:02making the world a better place for everyone by using them up!
0:06:02 > 0:06:05Now, I've fitted Oliver with a state-of-the-art Fact Nav system
0:06:05 > 0:06:09which contains all the scientific facts in the universe.
0:06:09 > 0:06:13All the facts are absolutely right, apart from all the ones that aren't.
0:06:13 > 0:06:15Thankfully, Oliver's pretty brainy himself
0:06:15 > 0:06:17and knows which ones are right,
0:06:17 > 0:06:19which ones are true and which ones are false.
0:06:19 > 0:06:22But it's up to the teams to decide first
0:06:22 > 0:06:26so, if it's true, teams, Oliver will do this.
0:06:26 > 0:06:28CAR HORN BLARES
0:06:28 > 0:06:31And if it's false, Oliver will let you know by doing this.
0:06:31 > 0:06:33FOG HORN BLARES
0:06:33 > 0:06:37We get the message. Let's get on with the first round, then.
0:06:37 > 0:06:38Are we ready?
0:06:38 > 0:06:41This is your first chance to earn some points, OK?
0:06:41 > 0:06:45Your first chance to earn some points here. Red Team, you go first.
0:06:45 > 0:06:47Your question is this.
0:06:47 > 0:06:51Hawaii is moving towards Japan at 7cm every year.
0:06:51 > 0:06:53Is that true or is that false?
0:06:53 > 0:06:56Talk amongst yourselves, give it some thought.
0:06:56 > 0:06:57Audience, what do we think?
0:06:57 > 0:06:59THEY CHEER
0:06:59 > 0:07:03All these light-flashing signs.
0:07:03 > 0:07:06You think... Nearly everybody... Just one there thinks it's false.
0:07:06 > 0:07:09Why do you think it's false and everyone else doesn't?
0:07:09 > 0:07:12- I don't know.- You don't know. Right, fine. You made it up.
0:07:12 > 0:07:14Everybody there thinks it's true.
0:07:14 > 0:07:16There's a few there think it's false.
0:07:16 > 0:07:18Red Team, have you conferred?
0:07:18 > 0:07:20- Yep.- Do you think it's true or false?
0:07:20 > 0:07:21- True.- Oliver, is it true or false?
0:07:21 > 0:07:23CAR HORN BLARES
0:07:23 > 0:07:25Wey-hey, well done!
0:07:25 > 0:07:28Your first chance to get some points and you got them.
0:07:28 > 0:07:31Well done, guys. Right, Yellow Team, let's move over to you.
0:07:31 > 0:07:33These are you first points at stake.
0:07:33 > 0:07:34Your question is this -
0:07:34 > 0:07:37most diamonds are over three billion years old.
0:07:37 > 0:07:40Is it true or is it false?
0:07:40 > 0:07:41You can confer. Have a chat.
0:07:41 > 0:07:45Audience is straight away thinking...true. Yeah?
0:07:45 > 0:07:46CHEERING
0:07:46 > 0:07:49Couple of falses. Let's find out what the Yellow Team thinks.
0:07:49 > 0:07:51Have you made up your minds?
0:07:51 > 0:07:54- Yes.- And what did you all agree?
0:07:54 > 0:07:55We think it's true.
0:07:55 > 0:07:57You think that it's true that most diamonds
0:07:57 > 0:07:59are over three billion years old?
0:07:59 > 0:08:01Oliver, is it true or false?
0:08:01 > 0:08:02CAR HORN BLARES
0:08:02 > 0:08:05It's true! Well done, Yellow Team.
0:08:05 > 0:08:08So we've got one point a piece. This, then, is your final question.
0:08:08 > 0:08:11This is different because this one needs an answer.
0:08:11 > 0:08:13Not just true or false.
0:08:13 > 0:08:15Write it down on the pads in front of you,
0:08:15 > 0:08:18and the team that gets nearest to the correct answer
0:08:18 > 0:08:19will win this round,
0:08:19 > 0:08:22because you might find it's difficult to be completely accurate.
0:08:22 > 0:08:27How many parts are there in a Boeing 747-400? That's an aeroplane.
0:08:27 > 0:08:29You're looking vague.
0:08:29 > 0:08:31It's a Boeing 747-400.
0:08:31 > 0:08:34How many parts are there in it?
0:08:34 > 0:08:36OK, if I can ask both teams -
0:08:36 > 0:08:39how many parts are there in a Boeing 747-400?
0:08:39 > 0:08:42Show me your answers, please, Red and Yellow teams. Let's have a look.
0:08:42 > 0:08:48We've got, from the Red Team, 2 million? 2 million parts.
0:08:48 > 0:08:50That would take a lot of building.
0:08:50 > 0:08:52HE LAUGHS
0:08:52 > 0:08:54- Yellow Team.- Yeah.
0:08:54 > 0:08:57- Have you elected a leader of your team yet?- Yeah.
0:08:57 > 0:08:59- And which one of you is it?- Me.
0:08:59 > 0:09:02Yeah. And...are you confident in your team's answer?
0:09:02 > 0:09:05- No, not really.- 128 parts.
0:09:05 > 0:09:08So, that was like wings, wheels...
0:09:08 > 0:09:10Well, the correct answer is...
0:09:10 > 0:09:126 million.
0:09:12 > 0:09:16You couldn't have been much further out there. I'm terribly sorry.
0:09:16 > 0:09:18So that means, for the Red Team,
0:09:18 > 0:09:20that's another point to you. Well done.
0:09:20 > 0:09:24So...the points now stand at...
0:09:25 > 0:09:27128! What were you thinking?!
0:09:27 > 0:09:31You couldn't build those stairs out of 128 parts!
0:09:42 > 0:09:43CHEERING AND APPLAUSE
0:09:43 > 0:09:47That's to come, but now it's time for Mini Science.
0:09:47 > 0:09:50Now, this the round where our contestants must conduct
0:09:50 > 0:09:54a scientific experiment using ordinary household objects.
0:09:54 > 0:09:56And to help me is my old science teacher, Mini Miss!
0:10:00 > 0:10:03I should point out that Mini Miss is 65 years old.
0:10:03 > 0:10:05Looking good for your age, Miss.
0:10:05 > 0:10:06Thank you, Richard.
0:10:06 > 0:10:09I know you're thinking she looks like a ten-year-old.
0:10:09 > 0:10:10That's because she is... NOW.
0:10:10 > 0:10:14You see, I wanted to bring back the teacher I knew as a child,
0:10:14 > 0:10:17so I invented a time machine which was great,
0:10:17 > 0:10:20but unfortunately it didn't work quite as planned,
0:10:20 > 0:10:22and Miss has come back a little younger.
0:10:22 > 0:10:25But you still know what you're talking about, don't you, Miss?
0:10:25 > 0:10:28Of course I do, Richard. I'm a professor in nuclear physics
0:10:28 > 0:10:30and I've been teaching for over 40 years.
0:10:30 > 0:10:32See? So what have you got for us this week?
0:10:32 > 0:10:35Well, today's teams are going to be playing Mug Man,
0:10:35 > 0:10:39and all you need is a plastic beaker, a postcard and some water.
0:10:39 > 0:10:41Mug Man? What do you do with these things?
0:10:41 > 0:10:45Well, place the postcard over the beaker, shiny side down.
0:10:45 > 0:10:48Now, turn the beaker upside down,
0:10:48 > 0:10:51still holding the bottom of it
0:10:51 > 0:10:54- and the postcard flat against the beaker.- Yes.
0:10:54 > 0:10:58Now, carefully remove your hand from underneath the postcard and,
0:10:58 > 0:11:01hey presto, the postcard should stay put.
0:11:01 > 0:11:04That's not glue, that's just water in there! Yeah!
0:11:04 > 0:11:06CHEERING
0:11:06 > 0:11:09Miss, has that got anything to do with air pressure?
0:11:09 > 0:11:11Correct, Richard. You WERE listening.
0:11:11 > 0:11:13All those years ago, I paid attention.
0:11:13 > 0:11:16That's because - now, let's think about this -
0:11:16 > 0:11:19air is actually heavier stuff than we think it is,
0:11:19 > 0:11:20and it's pushing down.
0:11:20 > 0:11:23It exerts a force in all directions and, in this case,
0:11:23 > 0:11:26when it's upside down against the card like that,
0:11:26 > 0:11:29the air can't put its pressure on top of the card
0:11:29 > 0:11:30because the cup's in the way,
0:11:30 > 0:11:33so the air pressure is actually pushing up on it as well,
0:11:33 > 0:11:35and that's holding it in place.
0:11:35 > 0:11:37- Correct.- So I was right.
0:11:37 > 0:11:40See, teams. Simple enough. Or is it?
0:11:40 > 0:11:42Can I ask a question, though, Miss?
0:11:42 > 0:11:45- Yes.- Where did you get that water from?
0:11:45 > 0:11:46From the pipe over there.
0:11:46 > 0:11:48Do you know where that pipe goes?
0:11:48 > 0:11:50Put it this way. I don't know about Mug Man.
0:11:50 > 0:11:53- It maybe should be Wee Male. - Richard!- Sorry. Sorry.
0:11:53 > 0:11:56Anyway, once you've assembled your Wee Male, it doesn't stop there,
0:11:56 > 0:11:59you've then got to deliver it, and you have to do that
0:11:59 > 0:12:03across this handy obstacle course that you might have noticed.
0:12:03 > 0:12:05So you set off, carry your Wee Male very carefully
0:12:05 > 0:12:08across the Bridge of Destiny, staying on this side.
0:12:08 > 0:12:12Don't fall in the nuclear tank. It's terrible. Down the stairs.
0:12:12 > 0:12:13Very difficult here.
0:12:13 > 0:12:16If the card falls off, you don't just run straight back.
0:12:16 > 0:12:19You've got to finish the course and then set off back.
0:12:19 > 0:12:22By now, the next team player will be getting theirs
0:12:22 > 0:12:24set up and ready to go. You duck under here, over here.
0:12:24 > 0:12:27This is when I tried to re-invent the bicycle.
0:12:27 > 0:12:30It didn't work. Then the Stepping Stones of Science.
0:12:30 > 0:12:33Pick your own route, but just be quick. That's the main thing.
0:12:33 > 0:12:35Get to the end. This is the tricky bit.
0:12:35 > 0:12:37You take the card off, the water falls in there.
0:12:37 > 0:12:39Keep hold of the beaker.
0:12:39 > 0:12:42You deliver your card, Yellow Team in the yellow post-box,
0:12:42 > 0:12:44Red Team in the red one, obviously.
0:12:44 > 0:12:47Then you've gotta get back, so back through here,
0:12:47 > 0:12:50being careful not to mess up anybody coming the other way,
0:12:50 > 0:12:53over the Bridge of Destiny. Dash, dash, dash, keeping the glass.
0:12:53 > 0:12:56Now it's time for the next person to go, but you don't just set off.
0:12:56 > 0:12:59This is a relay race, so I put my glass down
0:12:59 > 0:13:02and you have to high-five before you leave.
0:13:02 > 0:13:04Well hold your hand up, then, Max.
0:13:04 > 0:13:07There you go. Now you can set off and it's your turn. OK?
0:13:07 > 0:13:08Good luck, teams.
0:13:08 > 0:13:13You've got Some Time to do this. Just SOME time. And it starts...
0:13:13 > 0:13:15Now. Go!
0:13:19 > 0:13:24Both teams carefully taking their Some Time to prepare their Wee Male.
0:13:31 > 0:13:34And the Reds take the early lead,
0:13:34 > 0:13:37while the Yellows take a more tentative approach.
0:13:39 > 0:13:42The Red Team tackle the limbo pole with ease,
0:13:42 > 0:13:46and the Yellows? Ah...
0:13:57 > 0:13:59Red Team going very well there.
0:13:59 > 0:14:04Bit of a disaster for the Yellows, breaking my obstacle course!
0:14:04 > 0:14:05I built that!
0:14:20 > 0:14:23This is where it went wrong last time for Yellow, but they're...
0:14:23 > 0:14:27Oh, it's gone wrong again. That's what happened there.
0:14:27 > 0:14:29OK, they're through, they're through.
0:14:29 > 0:14:31Now the delivery.
0:14:36 > 0:14:38I think we'll allow that for Yellow,
0:14:38 > 0:14:41even though they wrecked my obstacle course!
0:14:45 > 0:14:48Right now, it's 2-1 to the Reds.
0:14:48 > 0:14:50Puts the Reds in front.
0:15:01 > 0:15:05They've wrecked the course again!
0:15:11 > 0:15:13You can see the science helping them across,
0:15:13 > 0:15:17the air pressure holding the card up, pressing it in place.
0:15:17 > 0:15:19There's no glue. It's just air pressure.
0:15:22 > 0:15:25Air actually exerts pressure as it has weight.
0:15:25 > 0:15:26Above our heads are miles of air
0:15:26 > 0:15:28which are pushing down on our heads,
0:15:28 > 0:15:30and the air pressure on your body is...
0:15:30 > 0:15:33Well, it's the equivalent of two elephants sitting on you.
0:15:33 > 0:15:37Luckily, the inside of your body has pressure in it and pushes outwards
0:15:37 > 0:15:40with the same force so you don't get squished.
0:15:40 > 0:15:42Maybe my body doesn't have enough pressure in it.
0:15:42 > 0:15:43That's why I'm short.
0:15:44 > 0:15:45Well done, Yellow.
0:15:45 > 0:15:47That's another one.
0:15:47 > 0:15:49They're beating the Reds.
0:15:52 > 0:15:55Time is up, time is up, time is up.
0:15:55 > 0:15:57Sorry, Yellow, time is up.
0:15:57 > 0:15:59Sorry, Yellow, that's it, time is up.
0:15:59 > 0:16:02Right, it's time for the big toss-up. Let's have a look.
0:16:02 > 0:16:04First of all, the Yellow Team
0:16:04 > 0:16:07successfully delivered three postcards, OK?
0:16:07 > 0:16:09Red Team - now, they're currently ahead
0:16:09 > 0:16:10two points to one for the Yellows,
0:16:10 > 0:16:14so let's see if this equalises it or puts them in the lead.
0:16:14 > 0:16:18We've got one, two, three, four for the Reds!
0:16:21 > 0:16:24Well done, Reds!
0:16:24 > 0:16:26If you think about it, all that we've just seen,
0:16:26 > 0:16:29all that running around on our obstacle course,
0:16:29 > 0:16:32relied on air pressure to hold that postcard on, cos it wasn't glue.
0:16:32 > 0:16:34That was just the air pressure pushing up.
0:16:34 > 0:16:37So air pressure's stronger than perhaps we thought,
0:16:37 > 0:16:39but how much stronger?
0:16:40 > 0:16:42Today, at our top-secret test facility,
0:16:42 > 0:16:46one of my loyal lab rats will perform a breathtaking experiment.
0:16:46 > 0:16:49He's going to crush a can
0:16:49 > 0:16:52using only the pressure of the air that we breathe.
0:16:55 > 0:16:58Take one small metal oil can,
0:16:58 > 0:17:01a gas burner,
0:17:01 > 0:17:04a bottle of water,
0:17:04 > 0:17:05and some matches.
0:17:05 > 0:17:08Now, I know that you would never use matches, but don't worry.
0:17:08 > 0:17:12This lab rat has been specially trained by me.
0:17:12 > 0:17:15Then part-fill the can with water.
0:17:16 > 0:17:20Bring to the boil over a moderate heat,
0:17:28 > 0:17:30remove from the flame,
0:17:30 > 0:17:34fasten the lid and allow to cool for a few moments.
0:17:40 > 0:17:44Bob's your uncle. One crushed can.
0:17:46 > 0:17:49This works because the water vapour from the boiling water
0:17:49 > 0:17:52pushes air out of the can.
0:17:52 > 0:17:55When the lid is replaced and the can cools,
0:17:55 > 0:17:57the water vapour turns back into water,
0:17:57 > 0:18:01leaving a partial vacuum where the air and gas had been.
0:18:01 > 0:18:04This means there's now extremely low pressure inside the can,
0:18:04 > 0:18:09so the higher pressure of the air outside crushes it.
0:18:10 > 0:18:13The experiment worked fine on a flimsy tin can,
0:18:13 > 0:18:17but will the same thing happen to a steel barrel?
0:18:17 > 0:18:20They seem pretty tough.
0:18:20 > 0:18:23We're going to fill one barrel with more water than the other
0:18:23 > 0:18:26to see if it makes any difference.
0:18:26 > 0:18:30Obviously, with my lab rats being both stupid and expendable,
0:18:30 > 0:18:32it's OK for them to do this sort of thing.
0:18:32 > 0:18:37I know you would never do anything as idiotic as this.
0:18:44 > 0:18:48Now we just have to wait for them to cool down.
0:18:48 > 0:18:52OK. Now, I hope everybody's been watching carefully
0:18:52 > 0:18:55because there's an extra point here, Yellow, Red teams.
0:18:55 > 0:18:57Which barrel do you think will crush first,
0:18:57 > 0:18:59or do you think neither will crush?
0:18:59 > 0:19:02So give me your answers, team. Yellows, what do you reckon?
0:19:02 > 0:19:05- The girl will go.- You reckon the girl's barrel will go first.
0:19:05 > 0:19:10- The man's one.- There's only one way for us to find out. Let's watch it.
0:19:10 > 0:19:11Let's see.
0:19:13 > 0:19:17A cool, refreshing spray with water should speed up the experiment.
0:19:21 > 0:19:23Or not.
0:19:23 > 0:19:25# So slowly
0:19:25 > 0:19:27# Time goes by
0:19:27 > 0:19:29# So slowly... #
0:19:29 > 0:19:30This isn't working.
0:19:30 > 0:19:33Let's bring out the big guns.
0:19:40 > 0:19:42HE SOBS
0:19:43 > 0:19:46I'm sorry about this.
0:19:46 > 0:19:49Our calculations must have been a bit off.
0:19:49 > 0:19:52You just can't get the staff these days.
0:19:57 > 0:20:01This is getting really boring.
0:20:01 > 0:20:03Let's step it up a gear.
0:20:06 > 0:20:09At last, the professionals are here.
0:20:09 > 0:20:11This should speed it up.
0:20:20 > 0:20:23And just to make sure, a bit of ice.
0:20:32 > 0:20:35Any time now...
0:20:48 > 0:20:51Success! The barrel with more water produced more water vapour.
0:20:51 > 0:20:54This created a greater vacuum,
0:20:54 > 0:20:57allowing the air outside to crush that barrel first.
0:20:57 > 0:20:59Eventually.
0:21:05 > 0:21:08That is an extra point to you, the Red Team,
0:21:08 > 0:21:11so that means we're now 4-1 to the Reds.
0:21:11 > 0:21:14Well done. Guys, we're into the final round now,
0:21:14 > 0:21:17so you need to go off and get changed cos there's
0:21:17 > 0:21:19an outfit required because of where you're going.
0:21:22 > 0:21:25Today's Messy Messy Mess Test is in the nuclear box,
0:21:25 > 0:21:27which is why you needed the protective suits.
0:21:27 > 0:21:31- You all comfortable?- Yeah. - I don't really care. Just wondering.
0:21:31 > 0:21:33If you see anything moving in there, don't touch it
0:21:33 > 0:21:35cos they've all got teeth.
0:21:35 > 0:21:37Quite frightening. This is the game.
0:21:37 > 0:21:42Each of these pods contains fabulous prizes like a robo-spider,
0:21:42 > 0:21:44an MP3 player and a toxic mutant
0:21:44 > 0:21:47which will be quite comfortable in there.
0:21:47 > 0:21:50The idea is to move these pods from this end of the box...
0:21:50 > 0:21:53Obviously, you can't use your hands cos they'd melt and drop off,
0:21:53 > 0:21:54so use these tongs instead.
0:21:54 > 0:21:56Pass them from one to another,
0:21:56 > 0:21:58down to the other end, and put them in the baskets.
0:21:58 > 0:22:01- Have you already been swimming in there?- What?
0:22:01 > 0:22:04There's a lot of it on your head! Get them all in the baskets.
0:22:04 > 0:22:07The team to move the most prizes across the nuclear box
0:22:07 > 0:22:08gets to take them home.
0:22:08 > 0:22:11The losing team has to blow theirs up.
0:22:11 > 0:22:13Red Team, you start first
0:22:13 > 0:22:16because you had the most points at this stage of the game,
0:22:16 > 0:22:19OK? They've earned you a five-second advantage,
0:22:19 > 0:22:22so when you hear the first nuclear alert, you start.
0:22:22 > 0:22:26Yellow Team, you can only begin when you hear the second nuclear alert.
0:22:26 > 0:22:29Don't worry, you will recognise it when you hear it.
0:22:29 > 0:22:32You've got Some Time to get as many prize pods as possible
0:22:32 > 0:22:34across the nuclear box into the baskets.
0:22:34 > 0:22:36You all understand the rules?
0:22:36 > 0:22:39Good, because that time, Red Team, starts...now!
0:22:39 > 0:22:42And the Reds are off,
0:22:42 > 0:22:45seemingly oblivious to the nuclear goo that surrounds them.
0:22:45 > 0:22:47That's the second siren,
0:22:47 > 0:22:50and the Yellows explode into the game like a coiled spring.
0:22:50 > 0:22:53Or perhaps more like a rusty old spring
0:22:53 > 0:22:56that hasn't sprung since it was a lad.
0:22:56 > 0:22:59Unlike the Red Team who've already got a prize pod.
0:23:07 > 0:23:11And a second prize pod for the Red Team! Is there no stopping them?
0:23:18 > 0:23:22I should point out, apart from the quite incredible danger
0:23:22 > 0:23:24of even being in the nuclear box,
0:23:24 > 0:23:26this is not easy.
0:23:29 > 0:23:33The Reds not just seizing the advantage here but taking it,
0:23:33 > 0:23:36making it their own and refusing to give it back.
0:23:36 > 0:23:40The toxic goo seems to have had a strange effect on the Yellows.
0:23:40 > 0:23:42Some Time actually seems to be slowing down
0:23:42 > 0:23:45in their area of the tank.
0:23:45 > 0:23:48They can't even keep hold of their hard hats.
0:23:52 > 0:23:54It's OK. My hands can't melt with the nuclear goo
0:23:54 > 0:23:56because I've had special ones made.
0:23:56 > 0:24:00If that was your hands, they'd just fizz and disappear.
0:24:02 > 0:24:05As the Reds' prize basket bulges ever more,
0:24:05 > 0:24:10the Yellows' solitary prize pod is looking lonely and confused.
0:24:11 > 0:24:13Oh, this is embarrassing now!
0:24:13 > 0:24:16When will Some Time run out and put them out of their misery?
0:24:23 > 0:24:25OK, that's it!
0:24:25 > 0:24:27Both teams, time is up.
0:24:27 > 0:24:31Things getting very tense in the nuclear box there, I noticed.
0:24:31 > 0:24:34It's not an easy game that. Right, let's count up and see who's won.
0:24:34 > 0:24:37I think it's quite clear because, Yellow Team, two.
0:24:37 > 0:24:40Wasn't easy that, was it? Sorry.
0:24:40 > 0:24:42Red Team, well, loads! How many are there in here?
0:24:42 > 0:24:47There's one, two, three, four, five, six, seven.
0:24:47 > 0:24:50Seven pods. Well done, Red Team. You win. Congratulations!
0:24:50 > 0:24:52CHEERING AND APPLAUSE
0:24:52 > 0:24:54So it's time now to have...
0:24:54 > 0:24:57If you're watching at home, never ever open a prize pod
0:24:57 > 0:25:01from a nuclear box without wearing gloves cos it would melt your hands.
0:25:01 > 0:25:04I've had mine specially made. They're proofed, they don't melt.
0:25:04 > 0:25:07I'm going to open these to see what you've won.
0:25:07 > 0:25:11I'm going to need help, for which I need my specially trained Ninja.
0:25:11 > 0:25:13The wheelbarrow full of prizes.
0:25:13 > 0:25:16Gee, I wish you wouldn't do that quite so near...
0:25:16 > 0:25:21Ninja Nan, finish with the Ninja stuff! Now we're doing the prizes.
0:25:21 > 0:25:23Thank you. Let's see what you've won. First of all,
0:25:23 > 0:25:25there is a Bop It game,
0:25:25 > 0:25:26a mineral dig...
0:25:26 > 0:25:28There's tons of stuff in here.
0:25:28 > 0:25:29You've won toxic mutants,
0:25:29 > 0:25:31several of them.
0:25:31 > 0:25:33Well, you are them now, so you get one each.
0:25:33 > 0:25:36You've won, oh, tons of stuff. Well done, Reds, for winning all that!
0:25:36 > 0:25:39CHEERING
0:25:39 > 0:25:43We'll get all those packed up for you to take home,
0:25:43 > 0:25:45but here's the difference.
0:25:45 > 0:25:46Losers, Yellow Team, I'm sorry.
0:25:46 > 0:25:49Let's have a look at what you would've won.
0:25:49 > 0:25:54You would've been taking home a prize egg, MP3 player,
0:25:54 > 0:25:55that would've been quite nice.
0:25:55 > 0:25:58I'm sorry but, you know, instead of taking them home,
0:25:58 > 0:26:01you're going to get the joy of blowing them up instead.
0:26:01 > 0:26:03It is time for Bidet Goes Bang!
0:26:11 > 0:26:13So, Yellows, how are you feeling?
0:26:13 > 0:26:17- OK.- Not bad. Reds, can you stop the smugness.
0:26:17 > 0:26:20I can feel it. Just cos you're taking your prizes home
0:26:20 > 0:26:22and you're about to blow yours up. Sorry.
0:26:22 > 0:26:25- MP3 player would've been quite nice, wouldn't it?- Yeah.
0:26:25 > 0:26:28You get to blow it up. Who's going to push the plunger?
0:26:28 > 0:26:31- All of us.- All of you? Oh, you see, there's team play.
0:26:31 > 0:26:33What went wrong in the game?
0:26:33 > 0:26:35We just couldn't pass it.
0:26:35 > 0:26:37It was quite difficult as it turns out.
0:26:37 > 0:26:39Well, look, your prizes are already in the bidet.
0:26:39 > 0:26:43There's no putting off this moment any longer, so are you ready?
0:26:43 > 0:26:44Well, step forward.
0:26:44 > 0:26:47You have to lift the plunger and don't push it down
0:26:47 > 0:26:50until we've done the countdown, or it'll go bang.
0:26:50 > 0:26:55- Are we ready for the countdown? - 5...4...3...2...1.
0:26:59 > 0:27:00All gone. All gone.
0:27:00 > 0:27:04Well, on today's show, we've learnt a lot about air pressure
0:27:04 > 0:27:05and how it works all around us,
0:27:05 > 0:27:09and we've done that by crushing some big barrels and running around
0:27:09 > 0:27:10with upside-down cups of wee.
0:27:10 > 0:27:14Don't try that at home, though, any of this. See you next time!
0:27:19 > 0:27:23Blast Lab was recorded before a live studio audience,
0:27:23 > 0:27:27which is more than I can say for my lab rats.
