0:00:35 > 0:00:37Thank you, thank you.
0:00:37 > 0:00:39Oh...
0:00:39 > 0:00:41Now that's, that's awkward.
0:00:41 > 0:00:45Sorry, I must get that fixed. Hello!
0:00:45 > 0:00:47CHEERING
0:00:51 > 0:00:53I'm Richard and this is my Blast Lab
0:00:53 > 0:00:56where I do all my top-level scientific experiments.
0:00:56 > 0:00:58Talking of which, don't go near that.
0:00:58 > 0:01:02Late last night I spilled some of my new super virus.
0:01:02 > 0:01:05And well I think, I think, the tape will keep it in.
0:01:05 > 0:01:07I say "think", it's more "hope"...
0:01:07 > 0:01:08Just don't touch it.
0:01:08 > 0:01:11I've got two teams to help me today and they'll be
0:01:11 > 0:01:15battling it out across a series of tough games and messy experiments
0:01:15 > 0:01:17to see who's got the biggest science brains.
0:01:17 > 0:01:19Both teams will win prizes
0:01:19 > 0:01:22but like every great experiment there's a twist.
0:01:22 > 0:01:24Fail the final challenge
0:01:24 > 0:01:27and they'll see their prizes go up in smoke, literally.
0:01:27 > 0:01:28Let's see what's in store.
0:01:40 > 0:01:44Now today's show has clashed with my SAS defence team's yoga classes.
0:01:44 > 0:01:47So, they can't be here to protect the lab.
0:01:47 > 0:01:50Instead my security takes the form of an old lady
0:01:50 > 0:01:52who eats Ninja Turtles for breakfast.
0:01:52 > 0:01:55Which has landed her in a bit of trouble with the RSPCA.
0:01:55 > 0:01:57It is my Ninja Nan.
0:01:58 > 0:02:00CHEERING
0:02:07 > 0:02:08Nice to see the doors are working.
0:02:08 > 0:02:11This is my Ninja Nan. Thanks for standing in.
0:02:11 > 0:02:15She may look fragile but she's actually a trained ninja.
0:02:15 > 0:02:17Yeah, deadly.
0:02:17 > 0:02:19WHIPPING
0:02:19 > 0:02:21You don't want to...
0:02:21 > 0:02:23You don't want to make her angry. You really don't.
0:02:23 > 0:02:26If you'd like to take your place in security, Nan?
0:02:26 > 0:02:29Nan, Nan, Nan! If you'd... Nan, Nan.
0:02:29 > 0:02:32If you'd like to take your place in security? Thank you very much.
0:02:32 > 0:02:35And off she goes, speeding across the lab.
0:02:35 > 0:02:38Speeding across... ah!
0:02:38 > 0:02:41As a kid I used to love watching the wrestling with my nan.
0:02:41 > 0:02:43Because she is one heck of a wrestler.
0:02:43 > 0:02:46You should see her. Nan, how are you doing?
0:02:46 > 0:02:48See if she's settled into the security zone.
0:02:48 > 0:02:49Are you there yet? There she is.
0:02:49 > 0:02:51Yes, she's settling in nicely.
0:02:51 > 0:02:55Oh, look, she's brought her sandwiches with her. Lovely.
0:02:55 > 0:02:58Nothing too chewy, I hope, mind those teeth stay in.
0:02:58 > 0:03:01Let's have a look at who's trying to get into my lab.
0:03:01 > 0:03:04There's a group of people claiming to be the Yellow Team.
0:03:04 > 0:03:06CHEERING
0:03:09 > 0:03:10Let's not get carried away
0:03:10 > 0:03:13because they say they're the Yellow Team. They might not be.
0:03:13 > 0:03:16Anybody tries to get in this lab. We have to be careful.
0:03:16 > 0:03:19I have my security checks here.
0:03:19 > 0:03:21You claim to be the Yellow Team, yeah?
0:03:21 > 0:03:23- Yup.- Tell me your names, please.
0:03:23 > 0:03:25- Thomas.- Tal.- Efedi.
0:03:25 > 0:03:28Thomas, Tal, Efedi. That checks out with the security file.
0:03:28 > 0:03:32In the security file it says, for your hidden talent, Tal...
0:03:32 > 0:03:36- you can speak Japanese.- Yup. - Can you?
0:03:36 > 0:03:42Yeah. Konnichiwa. Watashi wa no namae wa Tal desu. Watashi wa...
0:03:42 > 0:03:44Does anybody else here speak Japanese?
0:03:44 > 0:03:48Just in case he was saying something rude to me. OK, well I believe you.
0:03:48 > 0:03:50It also says body worm.
0:03:50 > 0:03:51What does that mean?
0:03:53 > 0:03:54It's a brakedance move.
0:03:55 > 0:04:01- Is that a body worm?- Yeah. - Fair enough, in that case I accept.
0:04:01 > 0:04:05You are the Yellow Team. You're cleared through security. Come in.
0:04:05 > 0:04:07CHEERING
0:04:07 > 0:04:10Welcome to Blast Lab. Nice to have you here.
0:04:10 > 0:04:14- Where are you all from?- Bishop's Stortford and we're team Try It!
0:04:14 > 0:04:16- Team what?- Try It!
0:04:16 > 0:04:18That's your own name?
0:04:18 > 0:04:22- Try It?- Yeah.- No, you're Yellow Team and that's that.
0:04:22 > 0:04:24OK, let's find out if the Red Team are there.
0:04:24 > 0:04:29Are the people in security claim to be... no, we can't tell yet.
0:04:29 > 0:04:32They could be anybody trying to break into the Blast Lab
0:04:32 > 0:04:35to find out about the top secret stuff in here.
0:04:35 > 0:04:38Like my new super virus that I spilt on the floor earlier.
0:04:38 > 0:04:40So, you claim to be the Red Team.
0:04:40 > 0:04:42Identify yourselves. Your names, please.
0:04:42 > 0:04:44- Fay.- Alex.- Katy.
0:04:44 > 0:04:47Alex, Katy and Fay. Yeah, that figures.
0:04:47 > 0:04:50OK, your hidden talent, it says...a motto.
0:04:50 > 0:04:53We all go to Guides. This is our promise.
0:04:53 > 0:04:57I promise that I will do my best to love my God, to save the Queen
0:04:57 > 0:05:01and my country, to help other people out and to keep the Guide law.
0:05:01 > 0:05:02That's the Guide's motto?
0:05:02 > 0:05:04- Yeah.- Well, you all knew it.
0:05:04 > 0:05:08You are cleared through security. Come on in, you are the Red Team.
0:05:08 > 0:05:12CHEERING
0:05:12 > 0:05:14I'm sorry about all the security.
0:05:14 > 0:05:17We can't be too careful and let just anybody in, OK?
0:05:17 > 0:05:18Where are you all from?
0:05:18 > 0:05:21We're from Newcastle and we're the Crash Bang Clan.
0:05:21 > 0:05:24Good. Not for today, you're the Red Team.
0:05:24 > 0:05:25It's time to play round one.
0:05:25 > 0:05:28So, teams, make your way to the positions, please.
0:05:28 > 0:05:30Away you go, get ready for round one.
0:05:30 > 0:05:32When it comes to performing experiments,
0:05:32 > 0:05:34I'm always a little rusty,
0:05:34 > 0:05:36but not quite as rusty as this guy. It is Oliver.
0:05:56 > 0:05:59Oliver loves nothing more than collecting facts
0:05:59 > 0:06:02to put in his high-tech Fact Nav system.
0:06:02 > 0:06:03Trouble is though,
0:06:03 > 0:06:06not all the scientific facts he's collected are correct.
0:06:06 > 0:06:09It's up to both our teams to decide what is true and what is false.
0:06:09 > 0:06:12So, this is how it's going to work.
0:06:12 > 0:06:14I'm going to ask both teams a science question.
0:06:14 > 0:06:16I'm going to tell them a fact.
0:06:16 > 0:06:19I'm going to tell them something scientific.
0:06:19 > 0:06:23They are going to have to tell me if that fact is true or false.
0:06:23 > 0:06:26If it's true, Oliver will do this.
0:06:26 > 0:06:29CAR ALARM RINGS AND HORN BLOWS
0:06:29 > 0:06:31And if it's false Oliver will tell us, like this.
0:06:31 > 0:06:33FOG HORN SOUNDS
0:06:33 > 0:06:35OK, everybody ready? You understand?
0:06:35 > 0:06:37Red Team, you go first.
0:06:37 > 0:06:39Here is your fact.
0:06:39 > 0:06:43There are mirrors on the moon. Is that true or false?
0:06:43 > 0:06:46Are there mirrors on the moon? You can have a chat, work it out.
0:06:46 > 0:06:49Let's see what the audience think. What do we reckon, guys?
0:06:49 > 0:06:53- False!- False?
0:06:53 > 0:06:57Nearly everybody thinking it's false there. Couple thinking it's true.
0:06:57 > 0:06:59Don't let the audience sway you.
0:06:59 > 0:07:01You come to your own conclusion.
0:07:01 > 0:07:05- True.- You think there are mirrors on the moon. You think it's true.- Yes.
0:07:05 > 0:07:07Oliver, tell us is it true or false?
0:07:07 > 0:07:08"TRUE" HORNS BLOW
0:07:08 > 0:07:11True. There are in fact mirrors on the moon.
0:07:11 > 0:07:13Astronauts left them there so that laser beams
0:07:13 > 0:07:15could be bounced off them from Earth.
0:07:15 > 0:07:19So we could measure as accurately as possible, within a few centimetres,
0:07:19 > 0:07:20the distance of the moon.
0:07:20 > 0:07:22So, you're right.
0:07:22 > 0:07:24They're not shaving mirrors,
0:07:24 > 0:07:28but there are mirrors on the moon. Right, Yellow Team, it's your turn.
0:07:28 > 0:07:31This is your science fact. Tell me if this is true or false.
0:07:31 > 0:07:35There a million bacteria in a millilitre of fresh water.
0:07:35 > 0:07:38A million bacteria in a millilitre of fresh water.
0:07:38 > 0:07:41Have a chat, think about how much water that is.
0:07:41 > 0:07:43Audience, what do we think?
0:07:43 > 0:07:46There are a million bacteria in a millilitre of fresh water.
0:07:46 > 0:07:48Is that true? True or false?
0:07:48 > 0:07:51THE MAJORITY SHOUTS: True!
0:07:51 > 0:07:55Quite a few round the back think false, the majority maybe true.
0:07:55 > 0:07:58Don't let them sway you. come to your own conclusion.
0:07:58 > 0:08:01- Did anybody happen to know that answer?- No.- No.
0:08:01 > 0:08:02OK, but what do you think?
0:08:02 > 0:08:04We think it's true.
0:08:04 > 0:08:06Oliver, is it true or false?
0:08:06 > 0:08:07"TRUE" HORNS SOUND
0:08:07 > 0:08:09Yeah, it is.
0:08:09 > 0:08:11Well done, it is.
0:08:11 > 0:08:13Did you also know that people
0:08:13 > 0:08:17can have up to 182 different types of bacteria living on their skin?
0:08:17 > 0:08:19I've gone all itchy thinking about that.
0:08:19 > 0:08:23Right, this is the third question. This one works a bit differently.
0:08:23 > 0:08:26This time I don't want you to tell me whether it's true or false.
0:08:26 > 0:08:29I want you to write down what you think is the answer.
0:08:29 > 0:08:31It may be quite a difficult question.
0:08:31 > 0:08:35So, I'm going to give the point to whichever team gets the closest
0:08:35 > 0:08:37to the real answer. So, you understand?
0:08:37 > 0:08:40OK, both teams, here is the question. This is for both of you.
0:08:40 > 0:08:45How many bits are there in a computer gigabyte?
0:08:45 > 0:08:49How many bits are there in a computer gigabyte?
0:08:49 > 0:08:52Put your pens away. Turn your clipboards round.
0:08:52 > 0:08:54Let's have a look at what you've answered.
0:08:54 > 0:08:58Reds have said 1024. Yellows have said 100.
0:08:58 > 0:09:01Well, the answer is actually
0:09:01 > 0:09:098,589,934,592.
0:09:09 > 0:09:11Little bit out there.
0:09:11 > 0:09:14Quite a lot out. Which means...
0:09:14 > 0:09:17you weren't even close but you were closest. The point goes to you.
0:09:17 > 0:09:20That's two points in total to the Red Team. Well, done!
0:09:20 > 0:09:23CHEERING
0:09:35 > 0:09:37CHEERING
0:09:37 > 0:09:40That's all coming up later.
0:09:40 > 0:09:44Now, when I was at school, I had a very clever science teacher
0:09:44 > 0:09:47and I invented a time machine to bring her here.
0:09:47 > 0:09:49Unfortunately, I had a rubbish maths teacher.
0:09:49 > 0:09:53So, I made a mathematical mistake and ended up bringing Miss back
0:09:53 > 0:09:54in the body of a 10-year-old.
0:09:54 > 0:09:57- And here she is.- Hello, Richard.
0:10:01 > 0:10:05Should point out that Mini Miss here is actually 65-years old.
0:10:05 > 0:10:07- And looking very good for your age.- Thank you.
0:10:07 > 0:10:11Thankfully your brain remained unchanged by the experience.
0:10:11 > 0:10:14Of course. I am a professor in nuclear physics
0:10:14 > 0:10:17and I've been teaching for over 40 years.
0:10:17 > 0:10:20See? So, what have you got for us this week?
0:10:20 > 0:10:23Today we're going to be looking at air pressure.
0:10:23 > 0:10:25Tell me what we're going to be doing.
0:10:25 > 0:10:29Right. Well, today's teams are going to be making a rocket launcher
0:10:29 > 0:10:31which they then have to fire over a bar.
0:10:31 > 0:10:33Each team will get three attempts
0:10:33 > 0:10:36and after each try the bar will be raised.
0:10:36 > 0:10:40The winning team is the one that has got the most rockets over the bar.
0:10:40 > 0:10:45Sounds brilliant, but also quite incredibly dangerous.
0:10:45 > 0:10:46How do we build rockets?
0:10:46 > 0:10:51Well, we have to attach this bottle to this snorkel,
0:10:51 > 0:10:53using tape around here.
0:10:53 > 0:10:57Then, each team will have a choice
0:10:57 > 0:10:59of which sort of paper they would like to use.
0:10:59 > 0:11:02To make their paper rockets, like these.
0:11:02 > 0:11:04- Simple.- Well, how does it work?
0:11:04 > 0:11:05You stamp on the bottle,
0:11:05 > 0:11:09and then all the air will fire up the snorkel and into the rocket.
0:11:09 > 0:11:13- Which makes it shoot into the air. - It's air pressure through there.
0:11:13 > 0:11:14That's very clever.
0:11:14 > 0:11:17Teams, do you all understand what you've got to do?
0:11:17 > 0:11:20OK, you have some time to do this.
0:11:20 > 0:11:22And it starts now.
0:11:22 > 0:11:23STARTING BUZZER
0:11:23 > 0:11:26What's the important things when they're doing this?
0:11:26 > 0:11:29The seal around the snorkel on the bottle,
0:11:29 > 0:11:32because if there's any air coming out between there,
0:11:32 > 0:11:35then all the air's not going to be coming out of the rocket.
0:11:35 > 0:11:39- What else?- The second thing is the different types of paper.
0:11:39 > 0:11:41You've given them three types of paper.
0:11:41 > 0:11:45Tissue paper, wrapping paper and just normal coloured paper.
0:11:45 > 0:11:47So, what's the difference?
0:11:47 > 0:11:49The tissue paper's rather un-sturdy, isn't it?
0:11:49 > 0:11:52So, it won't be as forceful.
0:11:52 > 0:11:54But also, what the paper is made of,
0:11:54 > 0:11:57they're going to slip off the launch more easily.
0:11:57 > 0:11:59- So, there's friction in there?- Yeah.
0:11:59 > 0:12:02Hurry up, teams. Not got long now.
0:12:02 > 0:12:03Oh, that's it.
0:12:06 > 0:12:08ALARM SOUNDS
0:12:08 > 0:12:11Teams, your time is up now, your time is up.
0:12:11 > 0:12:15So, you've all built your rockets and your launchers.
0:12:15 > 0:12:18Yellow Team, you guys have got to launch your rockets first.
0:12:18 > 0:12:21Come over to the rocket launch area. You've got three attempts at this.
0:12:21 > 0:12:25We'll raise the bar after each attempt. Which paper did you go for?
0:12:25 > 0:12:29- The proper paper.- The what?- Normal paper as opposed to tissue paper.
0:12:29 > 0:12:32- Why did you go for that? - Because we think it's tougher
0:12:32 > 0:12:34and it will keep a lot more air in.
0:12:34 > 0:12:37Who's going to be the rocket launcher? Who's going to stamp?
0:12:37 > 0:12:39- Me.- Why are you doing that?
0:12:39 > 0:12:41- I was chosen!- OK, fair enough!
0:12:41 > 0:12:44- You weren't a volunteer. - He's stronger than us.
0:12:44 > 0:12:47You can have your first attempt. Good luck to clear the bar.
0:12:47 > 0:12:49Right, when you're ready, fire.
0:12:50 > 0:12:52Very good height but it missed.
0:12:52 > 0:12:56We'll put the bar up to next height. You have two more goes at this.
0:12:56 > 0:12:59We will allow a little bit of tinker time in between each attempt.
0:12:59 > 0:13:03Because obviously, with science this far near the cutting edge,
0:13:03 > 0:13:05they need a bit of time to get things right.
0:13:05 > 0:13:07Machines like this can be temperamental.
0:13:07 > 0:13:10Are we set up and ready for our second launch?
0:13:10 > 0:13:13You've changed your tactics. You've moved the bottle around.
0:13:13 > 0:13:16The bar on it's higher setting. There's a point at stake.
0:13:16 > 0:13:18Good luck.
0:13:18 > 0:13:19Whoa! I'd say that cleared.
0:13:19 > 0:13:21Well done.
0:13:21 > 0:13:23CHEERING
0:13:23 > 0:13:27Right, we'll raise the bar, lab rats, to the top height, please.
0:13:27 > 0:13:29OK, are we ready for our final launch?
0:13:29 > 0:13:33OK. Yes! I'd say that cleared.
0:13:33 > 0:13:35Well done. That's two points.
0:13:39 > 0:13:41Well done, Yellow Team. Back to your table.
0:13:43 > 0:13:45Well done, Yellow Team. Two points for you.
0:13:45 > 0:13:49Reds, if you're ready let's have you down here at the rocket launch site.
0:13:49 > 0:13:53Were you watching what we going on with the other team?
0:13:53 > 0:13:55Were you? Did you learn from it?
0:13:55 > 0:13:57- Yes.- What did you learn?
0:13:57 > 0:13:58Not to face the bottle forward.
0:13:58 > 0:14:00You reckon that's the way to go?
0:14:00 > 0:14:03OK, well, good luck to you. Good luck.
0:14:03 > 0:14:05This is your first attempt.
0:14:05 > 0:14:07By the way, what paper did you use?
0:14:07 > 0:14:11- Wrapping paper.- That's different to what the Yellow Team used. Why?
0:14:11 > 0:14:13It's lighter and we think it'll fly smoother.
0:14:13 > 0:14:15You've thought about the aerodynamics of this.
0:14:15 > 0:14:17Good luck, this is your first launch.
0:14:17 > 0:14:21Who's doing the launching? Katy. Why were you chosen for this?
0:14:21 > 0:14:23I've done it before at a science museum.
0:14:23 > 0:14:25You've done it before? How many rockets have you built?
0:14:25 > 0:14:29- Well, I've done one and I got it the furthest.- You are a rocket scientist?
0:14:29 > 0:14:34- Not really.- You've said it now. She's a rocket scientist!
0:14:34 > 0:14:35Right, well, good luck.
0:14:35 > 0:14:37Whoa! OK, OK.
0:14:39 > 0:14:41Well, can't deny that that worked.
0:14:41 > 0:14:45If you'd like to get set up for your second attempt at the bar.
0:14:45 > 0:14:47Miss, they went for a different paper.
0:14:47 > 0:14:51I reckon, that the wrapping paper has less friction going on
0:14:51 > 0:14:52- because it's shiny.- Exactly.
0:14:52 > 0:14:55Although this is rocket science, there's friction going on.
0:14:55 > 0:14:58- Am I right?- Yes, you are. - See, I told you I was listening.
0:14:58 > 0:15:00OK, another point at stake.
0:15:00 > 0:15:04Good luck to you. Our second rocket attempt for the Red Team.
0:15:04 > 0:15:05Here we go.
0:15:06 > 0:15:08Yes, I'd say that's over.
0:15:10 > 0:15:13That means you're equal with the Yellow Team,
0:15:13 > 0:15:15who are looking a little concerned.
0:15:15 > 0:15:17Lads, they're blitzing you.
0:15:17 > 0:15:20I don't know... they used a different paper.
0:15:20 > 0:15:22Does it look like it's working better?
0:15:22 > 0:15:24- A little bit.- Why?
0:15:24 > 0:15:26I think because it's going to have...
0:15:26 > 0:15:29You know like, the wind's going to pass over it more easily.
0:15:29 > 0:15:33If you've got quite grippy paper all the force that comes out of here
0:15:33 > 0:15:35will be wasted getting rid of that grip.
0:15:35 > 0:15:38Whereas if it's slippy - no friction, zing! Away it goes.
0:15:38 > 0:15:42I'm going to give you a countdown for the highest height
0:15:42 > 0:15:44and it matters and it means you'll win this game.
0:15:44 > 0:15:47This is the decider. Get this and you win.
0:15:47 > 0:15:51Five, four, three, two, one.
0:15:52 > 0:15:53Oh, yes!
0:15:53 > 0:15:55Well, done.
0:15:58 > 0:16:01That couldn't be any clearer. Reds, you win that round.
0:16:01 > 0:16:03That's another point for you.
0:16:03 > 0:16:04You've got three points.
0:16:04 > 0:16:07Red, you are in the lead overall. Round of applause.
0:16:07 > 0:16:11APPLAUSE AND CHEERING
0:16:11 > 0:16:13Can I just say, I was looking at this whole set up here
0:16:13 > 0:16:14not at the lab rats,
0:16:14 > 0:16:17I try not to look at them unless I absolutely have to.
0:16:17 > 0:16:21But I was looking at the posts, the cross bar and the air pressure
0:16:21 > 0:16:25and I was thinking, there's something else we can do with that.
0:16:25 > 0:16:27And then I got it. I had a brilliant idea.
0:16:28 > 0:16:32Rugby - a game where strong men chase an egg around a pitch
0:16:32 > 0:16:35and get involved in a spot of rucking, mauling and eye gouging.
0:16:35 > 0:16:38But to be honest the kicking bit is a bit boring.
0:16:38 > 0:16:41So, my big idea this week
0:16:41 > 0:16:44is to make scoring conversions more interesting.
0:16:44 > 0:16:47But first we need to set up a little game.
0:16:47 > 0:16:50MUSIC: "Eye Of The Tiger" by Survivor
0:16:54 > 0:16:57Blimey! Have you seen the size of the opposition?
0:16:58 > 0:17:00HE SOBS
0:17:00 > 0:17:03ROARING
0:17:03 > 0:17:08I think my lab rats might just have bitten off more than they can chew.
0:17:08 > 0:17:12Oh well. If you can't take a bit of pain, best to stick to table tennis.
0:17:15 > 0:17:18# Rising up Back on the street
0:17:18 > 0:17:22# Took my time Took my chances... #
0:17:22 > 0:17:26Honestly, it's like that Hulk versus the Chuckle Brothers.
0:17:31 > 0:17:32WHISTLE BLOWS
0:17:35 > 0:17:38Come on, lab rats, it's only a bit of pain.
0:17:38 > 0:17:41Quite a lot of it. Get into them.
0:17:41 > 0:17:44Well, don't run away!
0:17:52 > 0:17:55Come on... get up, you wimps.
0:17:55 > 0:17:57Oh, this is just embarrassing.
0:18:00 > 0:18:02Come on, ref, that has to be a foul.
0:18:04 > 0:18:07The England team have got Johnny Wilkinson
0:18:07 > 0:18:10but Blast Lab have got something even better...
0:18:10 > 0:18:12an air cannon.
0:18:17 > 0:18:20Yeah, now who's looking scared?
0:18:20 > 0:18:25# A seven-nation army couldn't hold me back... #
0:18:25 > 0:18:28Three points and victory will be ours.
0:18:28 > 0:18:30Fire!
0:18:35 > 0:18:38Oh, bit of a slice on that one, I think.
0:18:41 > 0:18:44Well, that didn't go entirely to plan.
0:18:44 > 0:18:45An air cannon works
0:18:45 > 0:18:49by using compressed air to fire the rugby ball.
0:18:49 > 0:18:53When the air is released, it rapidly expands up the barrel of the cannon,
0:18:53 > 0:18:55shooting the ball out of the end.
0:18:55 > 0:18:58Hopefully towards the posts.
0:18:58 > 0:19:00But it's got me thinking.
0:19:00 > 0:19:04Johnny Wilkinson can slot a ball between the posts
0:19:04 > 0:19:05from a maximum of 40 to 50 metres.
0:19:05 > 0:19:09This is impressive, but can we do any better?
0:19:09 > 0:19:13I wonder if our compressed-air cannon can score a conversion
0:19:13 > 0:19:15from a massive 100 metres?
0:19:15 > 0:19:17That's further than my lab rats can run.
0:19:17 > 0:19:19OK. Well...
0:19:20 > 0:19:22..time to check if you were all paying attention
0:19:22 > 0:19:25and thinking about that one.
0:19:25 > 0:19:26Red Team, for an extra point,
0:19:26 > 0:19:29do they make the longest ever rugby conversion?
0:19:29 > 0:19:30Have a think.
0:19:30 > 0:19:33Yellow Team, it's the same for you as well.
0:19:33 > 0:19:36It's for an extra point. So, think of your answer.
0:19:36 > 0:19:39- Red Team, what are you going to say, yes or no?- We think it did.
0:19:39 > 0:19:42- You think it did?- Yes. - Do you think they did?
0:19:42 > 0:19:44We haven't decided yet.
0:19:44 > 0:19:47- Take your time, take your time, work it out.- No.
0:19:47 > 0:19:49So, that's no from the Yellows and you say?
0:19:49 > 0:19:51- Yes.- Yes. That's simple enough.
0:19:51 > 0:19:54Let's find out which team is right.
0:19:56 > 0:19:57OK, so here we go.
0:19:57 > 0:20:02The first of three attempts to score a conversion at 100 metres.
0:20:02 > 0:20:04The cannon is primed.
0:20:04 > 0:20:07The pressure is turned up to full and the ball is loaded.
0:20:07 > 0:20:09Fire!
0:20:09 > 0:20:12Wow, look at it go!
0:20:12 > 0:20:15It's gone somewhere up in the sky and...
0:20:17 > 0:20:19Oh, there it is
0:20:20 > 0:20:23On the wrong side of the runway.
0:20:23 > 0:20:24That'll be a miss, then.
0:20:24 > 0:20:27Hopefully that was just them getting their sights in.
0:20:33 > 0:20:34That was equally rubbish.
0:20:39 > 0:20:42This isn't basketball, so that doesn't count either.
0:20:42 > 0:20:46It's down to the last attempt and my lab rats have a cunning plan.
0:20:46 > 0:20:49The lightweight ball is difficult to aim.
0:20:49 > 0:20:51So, they're going to fill it with sand.
0:20:51 > 0:20:55Well, Johnny Wilkinson uses sand to balance his ball.
0:20:55 > 0:20:58So, it's not really cheating. Here we go...
0:20:58 > 0:20:59fire!
0:20:59 > 0:21:02The increased mass of our rugby ball
0:21:02 > 0:21:05means it has more momentum once on the move.
0:21:05 > 0:21:09And that means air resistance is less likely to knock it off course.
0:21:09 > 0:21:12It must have gone at least 200 metres.
0:21:12 > 0:21:16Did it go through the goal posts? Let's check another angle.
0:21:17 > 0:21:19Straight down the middle.
0:21:21 > 0:21:23It looks like game over, though.
0:21:25 > 0:21:29Well, that's a point for the Red Team.
0:21:30 > 0:21:33The Yellow Team's faces when they filled that ball with sand.
0:21:33 > 0:21:37I got the impression you wanted to object there, Tom.
0:21:37 > 0:21:39I didn't say they weren't going to fill it with sand.
0:21:39 > 0:21:43That was the problem. It's when the ball was light, even with all
0:21:43 > 0:21:46that much force behind it, it got deflected too easily. And it works.
0:21:46 > 0:21:48Four to the Reds, one to the Yellows.
0:21:48 > 0:21:50Both teams have got to go and get changed
0:21:50 > 0:21:52into your protective clothing.
0:21:52 > 0:21:55It's the Messy Messy Mess Test and you are going to need it.
0:21:55 > 0:21:58If there's an odd smell here. I'm sorry about the noise.
0:21:58 > 0:22:00It's not me, obviously.
0:22:00 > 0:22:03It's these guys, these lab rats here. These are the lab rats
0:22:03 > 0:22:07that we saw making pathetic fools of themselves playing rugby.
0:22:07 > 0:22:10Are we agreed they were pathetic playing rugby.
0:22:10 > 0:22:12So I've made them conduct an experiment
0:22:12 > 0:22:14to see how smelly my nan's socks are.
0:22:14 > 0:22:16Oh, man... that's, that's not good at all.
0:22:16 > 0:22:18So, I'm going to leave them to it
0:22:18 > 0:22:20and move on to the Messy Messy Mess Test.
0:22:24 > 0:22:27And today it is in the nuclear box.
0:22:27 > 0:22:31Which is why you guys needed those protective outfits. Very important.
0:22:31 > 0:22:34Actually, I've been keeping my goldfish in here recently.
0:22:34 > 0:22:37Are they supposed to have teeth?
0:22:37 > 0:22:40I think maybe they grew them inside. Just don't, don't pet them.
0:22:40 > 0:22:42Stay away from them.
0:22:42 > 0:22:46This is the game. These pods contain fabulous prizes in each one.
0:22:46 > 0:22:48Like a digital metal detector,
0:22:48 > 0:22:52a multi media MP3 player and a snotty slime clock.
0:22:52 > 0:22:53Every home should have one.
0:22:53 > 0:22:56The idea is to move these pods from this end of the box.
0:22:56 > 0:22:59You can't use your hands to do that which is why you've got these tongs.
0:22:59 > 0:23:01Otherwise your hands would melt and drop off.
0:23:01 > 0:23:04Move them right down to the other end of the box
0:23:04 > 0:23:06and drop them in these baskets at the other end.
0:23:06 > 0:23:10The team to move the most prizes across a nuclear box
0:23:10 > 0:23:11gets to take them home.
0:23:11 > 0:23:15The losing team has to blow their prizes up.
0:23:15 > 0:23:17Red team, you're going to start first
0:23:17 > 0:23:19because you have the most points.
0:23:19 > 0:23:21That has bought you a five-second advantage.
0:23:21 > 0:23:25So, when you hear the first nuclear alert, you start.
0:23:25 > 0:23:28Yellow, when you hear the second one, that's your cue
0:23:28 > 0:23:31to start moving those pods to the other end.
0:23:31 > 0:23:33- Does everybody understand?- Yep.
0:23:33 > 0:23:36Good, good. You have some time to get as many prize pods
0:23:36 > 0:23:38to the other end as you possibly can.
0:23:38 > 0:23:42And that time, Red Team, starts now.
0:23:42 > 0:23:48And away we go. Some fumbling by the Reds there.
0:23:49 > 0:23:50SIREN SOUNDS
0:23:50 > 0:23:52The second siren sounds.
0:23:52 > 0:23:53The Yellows are off
0:23:53 > 0:23:56and the Reds haven't made the most of their head start.
0:23:56 > 0:23:58And it's neck and neck,
0:23:58 > 0:24:01with both teams passing their pods in perfect symmetry.
0:24:01 > 0:24:06Disaster! A drop from the Yellows and a score from the Reds.
0:24:09 > 0:24:12Now there seems to be some confusion
0:24:12 > 0:24:15and more than a little stress in the Red camp.
0:24:15 > 0:24:19The Yellows taking advantage of the Red meltdown with another score.
0:24:21 > 0:24:24Some precision pod work from the Yellows there.
0:24:24 > 0:24:27Ultimate concentration but nothing more than we would expect
0:24:27 > 0:24:30from players such as these, at the top of their game.
0:24:37 > 0:24:38Another for the Yellows.
0:24:40 > 0:24:43And the Reds. Both teams scoring at will now.
0:24:43 > 0:24:45Careful, yellows, careful.
0:24:45 > 0:24:48Another prize pod down, very sad to see.
0:24:50 > 0:24:54All to play for now. It is too close to call.
0:24:59 > 0:25:03Another score for the Yellows and another score for the Reds.
0:25:05 > 0:25:07Time's nearly up, guys.
0:25:09 > 0:25:11SIREN SOUNDS
0:25:11 > 0:25:15That's it. That's it. Time is up. Let's see who has won.
0:25:15 > 0:25:18I can't handle these prize pods myself. My hands would melt.
0:25:18 > 0:25:20So, I'm using lab rats.
0:25:20 > 0:25:23They're disposable. So, let's see for the Yellow Team.
0:25:23 > 0:25:25How many pods have they got in their basket?
0:25:25 > 0:25:27Four for the Yellow. For Reds, how many have we got?
0:25:27 > 0:25:32Five, five. So that means, Reds, you are the winners. Well done!
0:25:32 > 0:25:34CHEERING
0:25:34 > 0:25:37And so, Red Team, let's see what prizes you are taking home.
0:25:37 > 0:25:41For that I shall need my very own ninja-trained nan.
0:25:41 > 0:25:44Red team, you are each taking home a Toxic Mutant,
0:25:44 > 0:25:47a Snotty Slime Clock,
0:25:47 > 0:25:49a microscope each.
0:25:49 > 0:25:51You've got a Bop It game,
0:25:51 > 0:25:54a lunar eclipse bedroom light, each of you. Well done.
0:25:54 > 0:25:57Each of you taking those prizes home.
0:25:58 > 0:26:01Now for the slightly awkward bit.
0:26:01 > 0:26:04Yellow, we'll find out what prizes you would have been taking home.
0:26:04 > 0:26:09You would have won, each of you, a electronic Meeba.
0:26:09 > 0:26:13A microscope for each of you,
0:26:13 > 0:26:16an MP3 player
0:26:16 > 0:26:19and a Snotty Slime Clock.
0:26:19 > 0:26:22But, Yellow Team, you're not taking those prizes home with you.
0:26:22 > 0:26:25Because you're going to blow them up.
0:26:25 > 0:26:27It is time for Bidet Goes Bang.
0:26:35 > 0:26:39Yellow Team, I daren't even ask, but how do you feel right now?
0:26:39 > 0:26:41- Devastated.- Dreadful.- Devastated?
0:26:41 > 0:26:44- Who is pushing the plunger to do this?- We all are.
0:26:44 > 0:26:45You're going to share it?
0:26:45 > 0:26:49Some people use dynamite to blow things up. Others use fireworks.
0:26:49 > 0:26:51I, however, use a bidet.
0:26:51 > 0:26:54It's the clean sophisticated way to explode things.
0:26:54 > 0:26:57OK, there's no putting it off any longer. Red Team, stop gloating.
0:26:57 > 0:27:02I can sense you gloating with your huge wheelbarrow full of prizes.
0:27:02 > 0:27:04Yellows, this is your moment.
0:27:04 > 0:27:07So, if you'd like to stand up to the plunger please,
0:27:07 > 0:27:09all of you together and lift it up.
0:27:09 > 0:27:13The system is now primed. If you are ready, it's time to count down.
0:27:13 > 0:27:18Five, four, three, two, one.
0:27:18 > 0:27:20There you go!
0:27:22 > 0:27:26You've done it now. That's all we've got time for.
0:27:26 > 0:27:29Thanks to the power of pneumatics, we've fired rockets,
0:27:29 > 0:27:31we've fired rugby balls down runways.
0:27:31 > 0:27:34If a certain two lab rats don't start pulling their weight round
0:27:34 > 0:27:37something else will be getting fired. I'll see you next time.
0:27:37 > 0:27:39Well done, Reds. Well done.
0:27:39 > 0:27:43I'm sorry, I'm sorry, Yellows.
0:27:47 > 0:27:51Blast Lab was recorded before a live studio audience.
0:27:51 > 0:27:54No lab rat was harmed during the filming
0:27:54 > 0:27:56and any who were, we recycled.
