0:00:35 > 0:00:37Right, would you like my autograph as well?
0:00:37 > 0:00:40It's my lab! He's just a lab rat.
0:00:40 > 0:00:43He can't even write, look. This is...pathetic.
0:00:43 > 0:00:47Oh, thank you. Hello and welcome to MY Blast Lab.
0:00:47 > 0:00:49Yeah.
0:00:49 > 0:00:51CHEERING AND APPLAUSE
0:00:51 > 0:00:56OK. Yeah, this is the BEST laboratory in the whole...
0:00:56 > 0:00:59OK, maybe not the best. The biggest laboratory in the whole...
0:00:59 > 0:01:02maybe not the biggest laboratory in the world.
0:01:02 > 0:01:06The best laboratory currently on television right now,
0:01:06 > 0:01:09with him in it and a big tank of toxic goo.
0:01:09 > 0:01:14Yeah, it is. Coming up in a moment, we'll have two teams of scientists,
0:01:14 > 0:01:18competing in top-level scientific challenges to win excellent prizes.
0:01:18 > 0:01:22With a mountain of knowledge and unfixable fountain of engine oil,
0:01:22 > 0:01:26it's Oliver and his soon-to-be world famous Fact Nav 2.0.
0:01:30 > 0:01:35In Mini Science, we witness a world first, and possibly...
0:01:35 > 0:01:38last, as our teams conquer friction by combining one of the slippiest
0:01:38 > 0:01:42man-made substances on the planet with giant frying pans.
0:01:46 > 0:01:49Meanwhile, my lab rats get their paws on a slow-motion camera
0:01:49 > 0:01:52and uncover the amazing world behind boring everyday things.
0:01:56 > 0:01:59And in this week's Messy Messy Mess Test, we play bridge.
0:01:59 > 0:02:03No, not Ninja Nan's favourite card game, but the one and,
0:02:03 > 0:02:06for planning permission reasons, the only Bridge of Destiny.
0:02:06 > 0:02:10'The Bridge of Destiny!'
0:02:10 > 0:02:14Yeah. Now, what would you say if I told you this high-security lab
0:02:14 > 0:02:16was only protected by an elderly lady?
0:02:16 > 0:02:18You'd probably say, "I know, Richard.
0:02:18 > 0:02:21"I've watched Blast Lab loads. She's a Ninja."
0:02:21 > 0:02:22And you'd be right. Here she is.
0:02:30 > 0:02:33Let's see what Ninja Nan and her friends from Cobra Squad are up to.
0:02:33 > 0:02:37Oh, no. Looks like things have got nasty.
0:02:37 > 0:02:40Somebody's only gone and done Ninja Nan's word search without asking.
0:02:40 > 0:02:44I feel bad now. It was me that did it. Let's not say anything.
0:02:44 > 0:02:49Let's instead have a look at who's trying to get into my lab today.
0:02:49 > 0:02:52CHEERING AND APPLAUSE
0:02:54 > 0:02:57Hello. So, you three say you're the Red Team. All right.
0:02:57 > 0:03:01We have to be sure. For security reasons, identify yourselves.
0:03:01 > 0:03:03- Ashley.- Michael.- Ronan.
0:03:03 > 0:03:06Ashley, Michael, Ronan. Yes, that checks out.
0:03:06 > 0:03:08Under talent, who's doing what for us?
0:03:08 > 0:03:10I can do kick-boxing.
0:03:10 > 0:03:13Oh, yes, yes, that's kick-boxing going on.
0:03:13 > 0:03:14Come on into the lab, please.
0:03:14 > 0:03:18APPLAUSE
0:03:19 > 0:03:21So you three claim to be the Red Team.
0:03:21 > 0:03:24Just before I can give you security clearance
0:03:24 > 0:03:27and full access to the lab, we have agreed a password.
0:03:27 > 0:03:29- What do you think it is?- Flying.
0:03:29 > 0:03:32Flying is what I've got written down here. Why that?
0:03:32 > 0:03:35- It was our first time flying yesterday.- To get to the lab?
0:03:35 > 0:03:38I believe you. You're accepted and pass through security.
0:03:38 > 0:03:42Go and get settled, ready for the first game. That is your Red Team.
0:03:42 > 0:03:44There they are.
0:03:44 > 0:03:47Great. We've got a Red Team. That's good.
0:03:47 > 0:03:51What we need now is a Yellow Team, and these three say it's them.
0:03:51 > 0:03:55CHEERING AND APPLAUSE
0:03:56 > 0:04:00Hello, hello. So, you three claim to be the Yellow Team.
0:04:00 > 0:04:02You could be anybody. Just for security reasons,
0:04:02 > 0:04:06- identify yourselves by name. - Zoe.- Jacob.- Aidan.
0:04:06 > 0:04:09Zoe, Jacob, Aidan, that's what I've got on the file here.
0:04:09 > 0:04:11What can you do to prove you are who you say?
0:04:11 > 0:04:13I can bend around a broom.
0:04:13 > 0:04:17I don't even understand. You'll have to demonstrate this.
0:04:17 > 0:04:18OK.
0:04:18 > 0:04:20Oh...oh!
0:04:20 > 0:04:23Ow! OK, fair enough. Eh... Well,
0:04:23 > 0:04:28I'm assuming nobody else here could do that so, yes, you can come in.
0:04:28 > 0:04:32APPLAUSE
0:04:32 > 0:04:35Right, we've agreed a password with the real Yellow Team.
0:04:35 > 0:04:38If you are, then you would know what it is.
0:04:38 > 0:04:39- Water.- I've got it written down.
0:04:39 > 0:04:42Why water? Because it's really important?
0:04:42 > 0:04:45Because when my mum was sunbathing,
0:04:45 > 0:04:48I threw a bottle of water out of the window on to her.
0:04:48 > 0:04:50Whoa, that was ill-advised!
0:04:50 > 0:04:53- I should explain, you're all brothers and sisters.- Yes.
0:04:53 > 0:04:55Happy family. Well, happy family
0:04:55 > 0:04:58- until that moment, I'm guessing. - Kind of.
0:04:58 > 0:05:00Well, fair enough. Water it is then.
0:05:00 > 0:05:04Go and get settled in. That is the Yellow Team. We have a Yellow Team.
0:05:04 > 0:05:07CHEERING
0:05:07 > 0:05:11Next, it's time to meet my favourite automobile in this lab.
0:05:11 > 0:05:14What it lacks in horsepower, he makes up for in headlight power.
0:05:14 > 0:05:17No, he doesn't. They're terrible. He makes up for
0:05:17 > 0:05:20in a horrible knocking sound in fourth. It is Oliver.
0:05:38 > 0:05:40CHEERING
0:05:40 > 0:05:44Let's get you docked into Fact Nav and get you connected up and ready.
0:05:44 > 0:05:49OK. Systems up and running. Good.
0:05:49 > 0:05:52Now, Oliver here has got Fact Nav 2.0.
0:05:52 > 0:05:55It's a system that can provide you with millions of scientific facts,
0:05:55 > 0:05:59when installed by a qualified professional.
0:05:59 > 0:06:04However, when it's installed by an unqualified amateur, like, me,
0:06:04 > 0:06:07for instance, about half the facts turn out to be wrong.
0:06:07 > 0:06:11This is where you come in. You have to tell me whether the science facts
0:06:11 > 0:06:13I give you are true or false.
0:06:13 > 0:06:16If they turn out to be true, Oliver will then let us know by doing this.
0:06:16 > 0:06:19CAR HORN BEEPS REPETITIVELY
0:06:19 > 0:06:22If they turn out to be false, he'll do this.
0:06:22 > 0:06:24FOG HORN WAILS
0:06:24 > 0:06:26That means false. Here's how we play the game.
0:06:26 > 0:06:29Each team has three red lights. Every time you answer
0:06:29 > 0:06:33a question correctly, I'll turn one of your lights green.
0:06:33 > 0:06:35The first team to get three green lights
0:06:35 > 0:06:38wins the game, they take a point and we move on.
0:06:38 > 0:06:40One important thing, though.
0:06:40 > 0:06:43If you get a question wrong, I'll light a light green
0:06:43 > 0:06:46for the other team. Understand the rules?
0:06:46 > 0:06:50- Yes.- Right. Teams, the first question is a nearest-to question.
0:06:50 > 0:06:55What is the highest recorded temperature on Mercury?
0:06:55 > 0:06:58What is the highest recorded temperature on Mercury?
0:07:03 > 0:07:08- 'Time's up.'- Yellows, what have you got? 253 degrees Celsius. Reds?
0:07:08 > 0:07:103,400 degrees Celsius.
0:07:10 > 0:07:13The real answer is...
0:07:13 > 0:07:17467 degrees Celsius, which means the Yellows are closest.
0:07:17 > 0:07:19It's a green light for the Yellows.
0:07:19 > 0:07:25Sorry, Reds. Don't worry. This game can turn so quickly.
0:07:25 > 0:07:28That means, Yellows, you've taken control of the game.
0:07:28 > 0:07:32You have a green light lit. You get the first true or false question.
0:07:32 > 0:07:33And here it comes.
0:07:33 > 0:07:40The owl noises, "too wit too woo" is actually made by two owls,
0:07:40 > 0:07:43not just one. Have a little chat and think about it.
0:07:43 > 0:07:45While you're doing that, Yellows,
0:07:45 > 0:07:49audience, vote with your feet. Is it true or false?
0:07:52 > 0:07:57Some frantic mind changing from some, then. I saw there was a bit of
0:07:57 > 0:08:00mind changing from you. You suddenly decided no, it's true, yeah?
0:08:00 > 0:08:02- Because it's very loud.- Yes.
0:08:02 > 0:08:04So, it must be made by two.
0:08:04 > 0:08:08- Oh, I see what you mean. - One could be very quiet.
0:08:08 > 0:08:10Yeah, volume is one theory. What do you reckon?
0:08:10 > 0:08:13I think it's false because
0:08:13 > 0:08:17it might be where the owl might have big lungs.
0:08:17 > 0:08:21- And it might make it loud. - So, owls have just got a loud voice.
0:08:21 > 0:08:24- What do you reckon? Made by one owl or two owls?- One.
0:08:24 > 0:08:27One owl. OK. Audience, thank you for your opinions.
0:08:27 > 0:08:29Pop back to your places.
0:08:29 > 0:08:32What do you think? The owl noise, "too wit too woo,"
0:08:32 > 0:08:35is actually made by two owls not just one.
0:08:35 > 0:08:37- Do you think that's true or false? - False.
0:08:37 > 0:08:39You think that's false. Oliver,
0:08:39 > 0:08:43please tell us, is that true or false?
0:08:43 > 0:08:44CAR HORN BEEPS
0:08:44 > 0:08:48It's true. You said false. That means a green light to the Reds,
0:08:48 > 0:08:51I'm sorry. The Reds get a green light.
0:08:53 > 0:08:58It's tawny owls that make the "too wit too woo" noise, in fact,
0:08:58 > 0:09:00and what we hear is a mixture of both the male
0:09:00 > 0:09:04and female owls calling to each other. It's quite romantic.
0:09:04 > 0:09:07Presumably one goes "too wit," and the other one goes "too woo".
0:09:07 > 0:09:12Or something like that. Reds, this is now you in the same position
0:09:12 > 0:09:15as the others were a moment ago. If you get this one right,
0:09:15 > 0:09:18you get two green lights. You're in good form.
0:09:18 > 0:09:21Get it wrong, and they can win it with their next question.
0:09:21 > 0:09:28The longest woman's fingernail in the world is 90cm long.
0:09:28 > 0:09:30Is that true or false? Have a think about it.
0:09:30 > 0:09:32I'm not going to hurry you for an answer.
0:09:32 > 0:09:36Audience, what do you think? Vote with your feet. Let's see.
0:09:42 > 0:09:46So...90cm for the longest woman's fingernail in the world.
0:09:46 > 0:09:49What do you think? Longest woman's fingernail, 90cm?
0:09:49 > 0:09:53I think it might be longer because I saw something in the newspaper...
0:09:53 > 0:09:55Longer found that? Oh, OK. And what do you think?
0:09:55 > 0:09:59I think it's too long to be someone's fingernail.
0:09:59 > 0:10:01How could it grow without breaking?
0:10:01 > 0:10:03- It's too long. - OK, audience, if you'd like to
0:10:03 > 0:10:06get back to your places, please. Now we know what you think,
0:10:06 > 0:10:09we're interested in what the Reds think
0:10:09 > 0:10:11because this is their question.
0:10:11 > 0:10:15The longest woman's fingernail in the world is 90cm long.
0:10:15 > 0:10:17- Is that true or false?- False.
0:10:17 > 0:10:21False? OK. Oliver, is that true or false?
0:10:21 > 0:10:23The Reds think it's false.
0:10:23 > 0:10:24CAR HORN BEEPS
0:10:24 > 0:10:28It's true! That means a second green light for the Yellows.
0:10:28 > 0:10:34There you go. The record is held by an American, Lee Redmond.
0:10:34 > 0:10:36She's not cut her nails since 1979.
0:10:36 > 0:10:40I love your faces. That's exactly it. 1979!
0:10:40 > 0:10:42Right, now the position is very interesting.
0:10:42 > 0:10:45This is to stay in the game. This is pretty important.
0:10:45 > 0:10:47Here comes your science fact.
0:10:47 > 0:10:52House flies live, on average, for two years.
0:10:52 > 0:10:54So, that's the science fact.
0:10:54 > 0:10:57Is it a fact? Is it true, or is it false?
0:10:57 > 0:11:02- False.- Oliver, for the game, is it true or false?
0:11:02 > 0:11:04FOG HORN WAILS
0:11:04 > 0:11:08It is false. That means another green light for the Yellows.
0:11:08 > 0:11:13CHEERING AND APPLAUSE
0:11:13 > 0:11:16In actual fact, house flies only have an average lifespan
0:11:16 > 0:11:20of two weeks and usually spend most of it buzzing around my septic tank,
0:11:20 > 0:11:23to be honest. Well done. It's 1-0 to the Yellows right now.
0:11:39 > 0:11:41When I set out all those years ago
0:11:41 > 0:11:44to build my very own time machine, I had no idea
0:11:44 > 0:11:49that my never-before-seen splicing of science fact with science fiction
0:11:49 > 0:11:53would lead to an often before seen result. Science failure.
0:11:53 > 0:11:55I say failure, it did work.
0:11:55 > 0:11:59Sort of, as the first person to use my time machine is about to prove.
0:11:59 > 0:12:02That, of course, is Mini Miss.
0:12:02 > 0:12:04APPLAUSE
0:12:09 > 0:12:12The first person to use your time machine, Richard,
0:12:12 > 0:12:14I'd like to suggest you also make that the last.
0:12:14 > 0:12:17Yes, Miss. Sorry, Miss, about the whole...
0:12:17 > 0:12:20She was my old science teacher and she still is my science teacher,
0:12:20 > 0:12:23just that she's come out of my time machine as a 10-year-old.
0:12:23 > 0:12:26I haven't got all day. Can we move on?
0:12:26 > 0:12:28Yes, what's today's game all about?
0:12:28 > 0:12:30Well, Richard, we'll be investigating friction
0:12:30 > 0:12:32by playing a game I like to call...
0:12:35 > 0:12:38I've seen curling. That's where they slide huge lumps of granite
0:12:38 > 0:12:40along the ice, like that.
0:12:40 > 0:12:43I've often thought, why not use smaller lumps of granite?
0:12:43 > 0:12:46It would make it easier. You could go a lot further.
0:12:46 > 0:12:48Yes, and another way to make it easier
0:12:48 > 0:12:51would be to replace the ice with a sheet of Teflon,
0:12:51 > 0:12:55one of the slipperiest man-made substances on the planet.
0:12:55 > 0:12:59That's what we've got here. A huge slide of the slippy substance.
0:12:59 > 0:13:03And in the background, we have these objects. So, each team has to choose
0:13:03 > 0:13:06an object and then put it in a giant frying pan,
0:13:06 > 0:13:09and attempt to slide them along the slippery surface
0:13:09 > 0:13:11into these scores zones.
0:13:11 > 0:13:15But, don't push too hard or the frying-pan will slip off the end
0:13:15 > 0:13:19and into the fire and you'll get no score at all for your push.
0:13:19 > 0:13:21What we've got is our super slippery surface,
0:13:21 > 0:13:24which means we've kept friction down to a minimum.
0:13:24 > 0:13:26What you guys have to do, teams,
0:13:26 > 0:13:29is give the right amount of momentum to the frying pan with your chosen
0:13:29 > 0:13:33object, so it slides down to the highest score possible before
0:13:33 > 0:13:37the bit of friction that is here actually makes it come to a stop.
0:13:37 > 0:13:39This is a game of skill and judgment.
0:13:39 > 0:13:42You're judging the amount of momentum required.
0:13:42 > 0:13:44Good luck with that. OK, let's go on with the game.
0:13:44 > 0:13:48Yellow Team, you one Fact Nav, you are ahead so you get to decide
0:13:48 > 0:13:50if you want to go first or second.
0:13:50 > 0:13:52Could we go second, please?
0:13:52 > 0:13:55OK. Reds are going first, Let's get on with it.
0:13:55 > 0:13:56Good luck both teams. Here we go.
0:13:59 > 0:14:03The Reds have been forced to go first and they've chosen the egg.
0:14:05 > 0:14:07AUDIENCE: Ooh...
0:14:07 > 0:14:11APPLAUSE
0:14:11 > 0:14:13That's three points for the Reds.
0:14:13 > 0:14:16Now, it's round one for the Yellows and they've gone for the burger.
0:14:16 > 0:14:20Will this fast food live up to its name?
0:14:24 > 0:14:26APPLAUSE
0:14:26 > 0:14:28Wow, nice call.
0:14:28 > 0:14:32That's five points for the Yellows. Good shot.
0:14:34 > 0:14:37They're going for the sausage.
0:14:37 > 0:14:40What? It's sausage. Good luck, Reds.
0:14:43 > 0:14:45APPLAUSE
0:14:45 > 0:14:48That's four points for the Reds.
0:14:51 > 0:14:56Yellows now choosing tomatoes. Can they beat what has gone before?
0:14:56 > 0:14:58Jacob trying to judge the momentum needed
0:14:58 > 0:15:01to score the most without going into the fire.
0:15:01 > 0:15:04Ooh!
0:15:04 > 0:15:07The Yellows showing us how it should be done with
0:15:07 > 0:15:13- a perfect score.- So that's seven points for the Yellows.
0:15:13 > 0:15:17It's not looking good for the Reds. They only have seven points
0:15:17 > 0:15:20to the Yellows' 12. They're going to need to get a maximum score
0:15:20 > 0:15:24to stand any chance of winning this game.
0:15:28 > 0:15:32It's a four. Still a good score. Good, safe score. Well done.
0:15:32 > 0:15:38- That's four points for the Reds. - With that last effort, it is now
0:15:38 > 0:15:41impossible for the Reds to win.
0:15:41 > 0:15:43The Yellows still have one more go, though,
0:15:43 > 0:15:45with the final item, the bacon. Here we go.
0:15:48 > 0:15:53APPLAUSE
0:15:53 > 0:15:56That's four points for the Yellows.
0:15:56 > 0:15:57Right, teams, we have finished.
0:15:57 > 0:16:00We have slid everything that we have to slide.
0:16:00 > 0:16:01And I can tell you that the...
0:16:01 > 0:16:06Well, here are the scores. Reds, you got 11, Yellows, 16.
0:16:06 > 0:16:09That means it's now 2-0 to the Yellows! Well done!
0:16:11 > 0:16:15It was a game of judgment, how much momentum to give it.
0:16:15 > 0:16:17Sorry. Don't worry, it's not over yet, Reds.
0:16:17 > 0:16:20All that sliding around was a bit fast-paced for me.
0:16:20 > 0:16:23My excitement-o-meter is measuring off the chart,
0:16:23 > 0:16:27by which I mean my heart's beating way too fast and I feel a bit sick.
0:16:27 > 0:16:29I think it's time we slowed things down a bit.
0:16:35 > 0:16:38Meet Slow Rider.
0:16:38 > 0:16:42This bad boy believes everything in life is better when done slowly.
0:16:42 > 0:16:45In fact, he's been living such a slowed-down life
0:16:45 > 0:16:48that he's developed the knack of viewing everyday occurrences
0:16:48 > 0:16:49in slow motion.
0:16:49 > 0:16:53Today, we've brought in a special slow-motion camera
0:16:53 > 0:16:56which will let us into his secret world of slowness.
0:16:56 > 0:17:00We'll be able to see things 40 times slower than they really are
0:17:00 > 0:17:03and find out just why he loves things going so slowly.
0:17:03 > 0:17:08We're using a camera that captures 40 times more images per second
0:17:08 > 0:17:11than the human eye, allowing us to see things as they actually happen
0:17:11 > 0:17:15rather than how we think they do. So, what's first on the menu?
0:17:15 > 0:17:17A lab rat eating a lemon.
0:17:21 > 0:17:23Well, Slow Rider seemed impressed.
0:17:23 > 0:17:25Let's take a closer look.
0:17:33 > 0:17:37Yeah, it is disgusting, but for some reason it's hard not to look.
0:17:41 > 0:17:44Next, a man with a fish.
0:17:51 > 0:17:53Amazing.
0:17:53 > 0:17:56Even on what is one of the slimmer lab rats, you can clearly see
0:17:56 > 0:18:01the skin rippling from the point of fish-on-face impact.
0:18:01 > 0:18:03What now?
0:18:03 > 0:18:08Two cream cakes. Ooh, I think I can see what's coming here.
0:18:08 > 0:18:12Comic genius. Now, let's take a look at that in slow motion.
0:18:24 > 0:18:27OK, all very entertaining, but this is Blast Lab,
0:18:27 > 0:18:29so it's time for an experiment.
0:18:29 > 0:18:33One lab rat and a balloon filled with water.
0:18:33 > 0:18:38When popped and watched at normal speed, it looks like this.
0:18:38 > 0:18:41All a bit messy. But what is happening?
0:18:41 > 0:18:43I feel a science graphic coming on.
0:18:43 > 0:18:46When the balloon is popped, there are several forces
0:18:46 > 0:18:50acting on the water, each affecting its shape and how it falls.
0:18:50 > 0:18:52First, there's gravity, which should
0:18:52 > 0:18:56pull each and every water molecule towards the ground at the same rate,
0:18:56 > 0:18:59making the water keep the exact shape of the balloon.
0:18:59 > 0:19:02Second, there's surface tension. This is made by the water molecules
0:19:02 > 0:19:05being sticky and clinging to each other.
0:19:05 > 0:19:09This surface tension acts to make the water a perfect ball shape.
0:19:09 > 0:19:11Finally, there's air resistance.
0:19:11 > 0:19:15This pushes on the water molecules as they fall through the air,
0:19:15 > 0:19:18making them spread out in all directions.
0:19:18 > 0:19:22OK, so there are three forces that can change the water's shape.
0:19:22 > 0:19:24When you watch the balloon burst with your own eyes,
0:19:24 > 0:19:28it's impossible to see what they actually do to the water.
0:19:28 > 0:19:32Let's watch it again, only this time with our special slow-motion camera.
0:19:32 > 0:19:36Will we see the water keep the shape of the balloon as it's popped,
0:19:36 > 0:19:38or will the water splash everywhere?
0:19:39 > 0:19:43OK, hold the experiment. There is a point up for grabs here, teams.
0:19:43 > 0:19:46The score is 2-0, I know, so you can't suddenly
0:19:46 > 0:19:49take the lead, but it'd be nice to win the point.
0:19:49 > 0:19:52I will give the point to the team that can tell me most accurately
0:19:52 > 0:19:54what happens. What do we think?
0:19:54 > 0:19:57Will the water be able to hold its shape?
0:19:57 > 0:19:58Yellows?
0:19:58 > 0:20:01- What do you think?- I think we'll be able to see it hold its shape.
0:20:01 > 0:20:03So you think just a balloon shape.
0:20:03 > 0:20:07- OK. Reds, what do you reckon?- We think the same, it'll keep its shape.
0:20:07 > 0:20:11Let's find out. There's only one way to do that. On with the experiment.
0:20:11 > 0:20:14So, we all think we know what happens
0:20:14 > 0:20:16when you pop a water balloon.
0:20:16 > 0:20:18But what REALLY happens?
0:20:18 > 0:20:20Let's find out.
0:20:34 > 0:20:38As the balloon breaks, some water droplets explode outwards,
0:20:38 > 0:20:40but the main bulk of the water
0:20:40 > 0:20:43actually holds the shape of the balloon before dropping.
0:20:49 > 0:20:51So there you have it.
0:20:51 > 0:20:56Water does actually hold the shape when it comes out of the balloon.
0:20:56 > 0:20:58That means it's a point to both teams.
0:20:58 > 0:21:02- Well done. Absolutely. Yeah. - CHEERING AND APPLAUSE
0:21:03 > 0:21:07Er... All right, you can have it back. Thank you, Michael.
0:21:07 > 0:21:10Erm, I just like popcorn. Thanks very much.
0:21:10 > 0:21:13Both teams get a point from that. The score now is 3-1.
0:21:13 > 0:21:15Reds and Yellows, away you go and get changed.
0:21:15 > 0:21:18CHEERING AND APPLAUSE
0:21:18 > 0:21:20It's good, though. It's salty.
0:21:20 > 0:21:23It's nice. That got my lab rats thinking,
0:21:23 > 0:21:27that experiment, though they don't think normally, like the rest of us.
0:21:27 > 0:21:30Looks like Slow Rider has taken his leave.
0:21:30 > 0:21:34A lab rat in charge of an expensive piece of camera equipment?
0:21:34 > 0:21:37Now, that's a recipe for disaster if I ever saw one.
0:21:37 > 0:21:41Slow motion of a ball being kicked, eh? Well, let's see what happens.
0:21:41 > 0:21:43You can see the ball compressing against the foot
0:21:43 > 0:21:46before shooting off.
0:21:46 > 0:21:48Very impressive. I take it all back.
0:21:48 > 0:21:50Ah, he's hit the camera. Wait till I get my hands on you.
0:21:50 > 0:21:55All right. And now it's time for...
0:21:58 > 0:22:01In that tank with you are pieces of a bridge - a bridge better known as
0:22:01 > 0:22:03the Bridge of Destiny.
0:22:03 > 0:22:06DRAMATIC, AMERICAN ACCENT: The Bridge of Destiny!
0:22:06 > 0:22:08You have to find all the pieces you can
0:22:08 > 0:22:11in that gunge to make the bridge to drive your cars across.
0:22:11 > 0:22:14It's that simple. The team that crosses it first
0:22:14 > 0:22:16will win all the prizes in the car's trailer -
0:22:16 > 0:22:19like radio-controlled spider, bionic copter.
0:22:19 > 0:22:22You'll win one of those each. Know what you're doing?
0:22:22 > 0:22:25- Yeah.- If we're ready, let's play the Bridge of Destiny.
0:22:25 > 0:22:29HIGH-PITCHED: # The Bridge of Destiny! #
0:22:29 > 0:22:34HE HOLDS THE NOTE
0:22:35 > 0:22:38Yellow Team, you're in the lead right now,
0:22:38 > 0:22:40so you get the five-second head start.
0:22:40 > 0:22:44Reds, you go on the second siren, not before, OK? Everybody know
0:22:44 > 0:22:47what they're doing? Good luck in the race to get your cars across.
0:22:47 > 0:22:49Let's start...now!
0:22:49 > 0:22:52And it's the Yellows who have the advantage,
0:22:52 > 0:22:55but will they make it count?
0:22:55 > 0:22:56There go the Reds.
0:22:56 > 0:23:00It's a battle out there today, with neither team taking prisoners.
0:23:00 > 0:23:03No time for pleasantries in this game.
0:23:03 > 0:23:06Both teams struggling to impose themselves at the moment,
0:23:06 > 0:23:09opting for the "square peg in a round hole" tactic,
0:23:09 > 0:23:10which, I can tell you,
0:23:10 > 0:23:14has not been the most successful technique in times past.
0:23:14 > 0:23:18There's certainly no lack of effort on display today.
0:23:18 > 0:23:21Hard to tell who's doing best - or who's doing worst -
0:23:21 > 0:23:24with both teams desperately trying to build a bridge
0:23:24 > 0:23:27maybe as slowly as possible.
0:23:27 > 0:23:30I did explain the rules, didn't I? Did I?
0:23:30 > 0:23:33And as if things weren't bad enough,
0:23:33 > 0:23:37that sounds like my sickly robot Alan about to sneeze.
0:23:37 > 0:23:40Lovely. Why is it blue? Please don't write in.
0:23:40 > 0:23:42I don't want to know. Back to the game.
0:23:42 > 0:23:46Has there been any progress whatsoever?
0:23:46 > 0:23:49Well, yes, both teams seem to have woken from their slumber
0:23:49 > 0:23:51and are desperately close to finishing their bridges.
0:23:51 > 0:23:54It really is anyone's game now.
0:23:54 > 0:23:57And I think the Yellows might have the edge,
0:23:57 > 0:23:59but it's too close to call.
0:23:59 > 0:24:02Oh, not again. Alan's about to add to the confusion.
0:24:05 > 0:24:08Oh, thanks so much for your input, Alan(!) Always welcome.
0:24:09 > 0:24:12This is the closest finish I've ever seen. Red? Yellow? I don't know!
0:24:12 > 0:24:14The crowd doesn't know.
0:24:16 > 0:24:18It's Yellows that have pulled their lever first
0:24:18 > 0:24:20to release the prize wagon.
0:24:20 > 0:24:23Will it slip? It's slipping, it's slipping, but it's over.
0:24:23 > 0:24:27A majestic win for the Yellows. Bad luck, Reds.
0:24:27 > 0:24:29Yeah, I'd say, Yellows,
0:24:29 > 0:24:32you got your car safely across the bridge, and then some!
0:24:32 > 0:24:35While we pick those up, that can be only one result, then.
0:24:35 > 0:24:37It's a win for the Yellows! Well done!
0:24:37 > 0:24:40CHEERING AND APPLAUSE
0:24:40 > 0:24:44Let's have a look at what you've won. Are you ready?
0:24:44 > 0:24:47Each of you will take home Tomb of Doom,
0:24:47 > 0:24:50Bionic Copter,
0:24:50 > 0:24:53Lunar Eclipse Bedroom Light,
0:24:53 > 0:24:56a puzzle cube for each of you,
0:24:56 > 0:25:00radio-controlled spider for each of you,
0:25:00 > 0:25:02flying UFO,
0:25:02 > 0:25:05bouncy balls,
0:25:05 > 0:25:07and a metal detector.
0:25:07 > 0:25:09CHEERING AND APPLAUSE
0:25:09 > 0:25:11That's all great news on this side of the tank.
0:25:11 > 0:25:14Over here, slightly different. Unlucky, losing team.
0:25:14 > 0:25:18Funnily, you would actually have won exactly the same prizes.
0:25:18 > 0:25:20You'd each have taken home all of those.
0:25:20 > 0:25:23But of course, only one team can go home with their prizes,
0:25:23 > 0:25:27the other goes home with what they came with - nothing.
0:25:27 > 0:25:29Because it's time for Bidet Goes Bang!
0:25:36 > 0:25:39Well done. Fair enough.
0:25:39 > 0:25:43So, two teams of brothers and sisters came to the Blast Lab -
0:25:43 > 0:25:46one, the Yellows, leaving happily with all of these prizes.
0:25:46 > 0:25:50These are all yours. Yeah, feeling good! Yeah, right, well done!
0:25:50 > 0:25:51CHEERING AND APPLAUSE
0:25:51 > 0:25:54Congratulations. The other team of brothers and sisters,
0:25:54 > 0:25:58the Reds, it's a different mood going on,
0:25:58 > 0:26:01because you did really well all the way through. You were great sports.
0:26:01 > 0:26:03And then you lost. I'm really sorry,
0:26:03 > 0:26:06and so it is with a heavy heart that I must ask you to do this.
0:26:06 > 0:26:10I say heavy heart - it could just be indigestion. Either way, follow me.
0:26:10 > 0:26:13It's time for the Walk of Shame. Let's do it.
0:26:13 > 0:26:15Thank you, audience.
0:26:15 > 0:26:18- SAD MUSIC PLAYS - Oh! It's sad.
0:26:22 > 0:26:25Oh, it's heartbreaking.
0:26:26 > 0:26:28It is sad.
0:26:31 > 0:26:32OK.
0:26:34 > 0:26:37Reds, there's no nice way of putting this, really. You lost.
0:26:37 > 0:26:40What you're going to do instead of taking your prizes is...
0:26:40 > 0:26:43- Blow them up.- ..blow 'em up, yeah, that's what we're going to do.
0:26:43 > 0:26:46You played really well all through. Hope you enjoyed it.
0:26:46 > 0:26:48I'm sorry you couldn't win.
0:26:48 > 0:26:50So, if you'd like to lift the plunger...
0:26:50 > 0:26:53- Yes! - ..united as a family team,
0:26:53 > 0:26:56sharing the blame together for blowing to bits
0:26:56 > 0:26:58all the prizes they'd love to take home.
0:26:58 > 0:27:01If we're ready, audience, let's count them down. From five...
0:27:01 > 0:27:04AUDIENCE: Four, three, two, one!
0:27:13 > 0:27:16Well, today has been a good day.
0:27:16 > 0:27:19We've learnt about friction by putting objects in giant frying pans
0:27:19 > 0:27:22and studied some frankly funny phenomena in slow motion.
0:27:22 > 0:27:25So from the lab rats and me, it's goodbye.
0:27:25 > 0:27:28Actually, the lab rats have barely noticed the show's even started,
0:27:28 > 0:27:31so it's just goodbye from me, really. Goodbye!
