0:00:33 > 0:00:35CHEERING AND APPLAUSE
0:00:37 > 0:00:39Thank for that. Shut the gate, shut the gate.
0:00:39 > 0:00:43You know they brought dinosaurs back from extinction in Jurassic Park?
0:00:43 > 0:00:45Well, I just did the same with the dodo,
0:00:45 > 0:00:49and boy, those critters are not as friendly as you would've thought.
0:00:49 > 0:00:51MENACING GROWLS
0:00:51 > 0:00:54OK, that wasn't one of my best ideas.
0:00:54 > 0:00:56Welcome again to my Blast Lab.
0:00:56 > 0:00:59CHEERING AND APPLAUSE
0:00:59 > 0:01:03Thank you. This is where I perform all my top secret experiments,
0:01:03 > 0:01:06so secret, in fact, that the only people who know about them
0:01:06 > 0:01:10are you, the lab rats, Ninja Nan, all these guys behind me,
0:01:10 > 0:01:14two teams of contestants who join me today to compete for great prizes,
0:01:14 > 0:01:16the postman, my mum and the pizza delivery guy.
0:01:16 > 0:01:19Actually, it's not really that secret at all, is it?
0:01:19 > 0:01:21Anyway, coming up, we have more facts
0:01:21 > 0:01:25than you could possibly fit in his boot, my good friend, Oliver.
0:01:29 > 0:01:34In Mini Science, our teams will try to bounce their way to victory.
0:01:38 > 0:01:41Meanwhile, our lab rats will be assaulting science head-on with...
0:01:41 > 0:01:44Well, with salt, and I do mean lots of salt.
0:01:47 > 0:01:49They're ill, they need some pills
0:01:49 > 0:01:52and they'll make you squeal, they are my Snot Bots.
0:01:52 > 0:01:56AUDIENCE: Eurgh!
0:01:56 > 0:01:59Now my super secret lab needs a super strong security guard.
0:01:59 > 0:02:02By night she's a Ninja, but by day...
0:02:02 > 0:02:05well, she's asleep because she gets tired staying up all night.
0:02:05 > 0:02:08She is, of course, my Ninja Nan.
0:02:15 > 0:02:19Let's have a look at what she's up to over in the Ninja Nannex today.
0:02:19 > 0:02:23Oh, no, hang on, one of our lab rats is about to steal one of her sweets.
0:02:23 > 0:02:26I wouldn't do that if I was him.
0:02:26 > 0:02:30Yeah, ooh! Yeah, he never ever learns.
0:02:30 > 0:02:33Right, let's have a look at who's trying to get into my lab today.
0:02:39 > 0:02:41Hello, so you reckon you're the Red Team
0:02:41 > 0:02:44and you want to come into the Blast Lab?
0:02:44 > 0:02:47OK, well you'll have to prove it, identify yourselves by name.
0:02:47 > 0:02:49- Shona.- Esme.- Plum.
0:02:49 > 0:02:52Shona, Esme, Plum, yes, I've got that written down
0:02:52 > 0:02:53on the security file here.
0:02:53 > 0:02:56Talent, Esme, I've got written down. What can you do?
0:02:56 > 0:02:58I can touch my head with my foot.
0:02:58 > 0:03:02That's what I've got written down here. Well, go on then.
0:03:02 > 0:03:05Oh, wow... Hang on... Wow!
0:03:05 > 0:03:07You did! OK, fair enough, come on in.
0:03:11 > 0:03:14Obviously, girls, I could touch the side of my head with my foot,
0:03:14 > 0:03:15but I choose not to.
0:03:15 > 0:03:19Welcome to Blast Lab, but you're not entirely cleared through security.
0:03:19 > 0:03:20One final check,
0:03:20 > 0:03:24we agreed a security password with the real Red Team.
0:03:24 > 0:03:27- You'd know it if you are them, what d'you think it is?- Tree.
0:03:27 > 0:03:29That's what I've got written down here.
0:03:29 > 0:03:31It's a nice word, I like trees.
0:03:31 > 0:03:34Is there any reason why you went for that as your password?
0:03:34 > 0:03:37Me, Esme and Shona got stuck up a tree one time,
0:03:37 > 0:03:39when we noticed it was smaller than us.
0:03:39 > 0:03:42You climbed a tree that was smaller than you?
0:03:42 > 0:03:45OK, OK, and you got stuck in a tree that was smaller than you?
0:03:45 > 0:03:47OK, there's no trees in here to climb.
0:03:47 > 0:03:49You are the Red Team, that's a good thing.
0:03:49 > 0:03:52Go and get ready for the first round.
0:03:52 > 0:03:53They are the Red Team.
0:03:53 > 0:03:55Officially through security.
0:03:55 > 0:03:57Right, let's meet the bunch of people
0:03:57 > 0:04:00claiming to be their opposition, the Yellow Team.
0:04:05 > 0:04:08Hello. So, you're the Yellow Team, are you?
0:04:08 > 0:04:11You'll have to prove it. Identify yourselves by name,
0:04:11 > 0:04:12the three of you.
0:04:12 > 0:04:15- Daniel.- Lewis.- Emma.
0:04:15 > 0:04:18Daniel, Lewis and Emma, OK, I've got that down here.
0:04:18 > 0:04:19What will you do as a talent
0:04:19 > 0:04:22to demonstrate you are the right Yellow Team?
0:04:22 > 0:04:26- A magic trick.- Daniel, it does have your name and "magic trick"
0:04:26 > 0:04:29written down here. What are you going to do? Show me.
0:04:29 > 0:04:33That's your hand in your pocket. Oh, hang on, what's that?
0:04:33 > 0:04:35Is that a coin in your hand, there?
0:04:35 > 0:04:36- Yeah.- Yeah, OK, right.
0:04:36 > 0:04:39Oh, you've put it in your mouth... This is...
0:04:39 > 0:04:41Oh, don't try this at home. Wow!
0:04:41 > 0:04:44OK, fair enough, that was some decent magic, come on in.
0:04:46 > 0:04:50Hello, Yellow Team, you are through this far. But one final check...
0:04:50 > 0:04:53We did agree a password with the real Yellow Team.
0:04:53 > 0:04:54If you are them you'd know what it is.
0:04:54 > 0:04:57- What d'you think it is?- Maddie. - Maddie.
0:04:57 > 0:04:59That's what I've got written down here. Why?
0:04:59 > 0:05:02Is that somebody's name? Daniel, Lewis and Emma?
0:05:02 > 0:05:04Why Maddie?
0:05:04 > 0:05:06It's because our auntie's dog,
0:05:06 > 0:05:10Maxie always has a "maddie" when we go round to see my auntie.
0:05:10 > 0:05:12No way! What's a maddie?
0:05:12 > 0:05:15It's when he goes... He gets really excited and he goes a bit mad.
0:05:15 > 0:05:16Does he, really?
0:05:16 > 0:05:19OK, nobody but the real Yellow Team could have known that.
0:05:19 > 0:05:22You're the Yellow Team, go and get ready for the first round.
0:05:22 > 0:05:25We have our teams.
0:05:25 > 0:05:28We need one more thing. He has a well-rounded knowledge of the world,
0:05:28 > 0:05:32and slightly less well-rounded tyres. He is, of course, Oliver.
0:05:52 > 0:05:57Young Oliver, there you go, he's docked, let's just connect him up.
0:05:57 > 0:06:00OK, good stuff, Fact Nav is on.
0:06:00 > 0:06:01Now I do like to keep up to date,
0:06:01 > 0:06:04so when I heard there was an upgrade to Fact Nav 2.0 for Oliver,
0:06:04 > 0:06:06I had to have it straight away.
0:06:06 > 0:06:09So I went online and downloaded it, and it is brilliant,
0:06:09 > 0:06:13millions and millions more bonkers and fascinating facts.
0:06:13 > 0:06:17One slight issue, there was a power cut halfway through
0:06:17 > 0:06:21the download, so quite a lot of them now aren't quite right.
0:06:21 > 0:06:24So teams, that's where you come in, cos I need
0:06:24 > 0:06:28you to tell me if the science facts I give you are true or false.
0:06:28 > 0:06:32If they turn out to be true, Oliver will let us know by doing this.
0:06:32 > 0:06:34HORN TOOTS
0:06:34 > 0:06:37And if they are false, Oliver will do this.
0:06:37 > 0:06:39HORN HONKS
0:06:39 > 0:06:41OK, so here's how we play the game.
0:06:41 > 0:06:43Both teams have three lights, currently lit red.
0:06:43 > 0:06:47When you answer a question correctly, one will go green.
0:06:47 > 0:06:51The first team to get all three lights lit green wins the round
0:06:51 > 0:06:53they win a point and we move on. Simple.
0:06:53 > 0:06:56Just one extra slightly cruel addition in that if you answer
0:06:56 > 0:07:01a question correctly, either team, you get your light lit green.
0:07:01 > 0:07:05If you get it wrong, we light one of their lights green,
0:07:05 > 0:07:08so it's possible you could win the game for them,
0:07:08 > 0:07:09or the other way round.
0:07:09 > 0:07:14So concentrate, think very hard before you answer a question.
0:07:14 > 0:07:18The first question is to sort out who gets the first light lit green
0:07:18 > 0:07:20and who takes control of the game.
0:07:20 > 0:07:24So this is important, this is a nearest to question.
0:07:24 > 0:07:28On Earth it takes one year to complete an orbit,
0:07:28 > 0:07:31a lap around the sun.
0:07:31 > 0:07:32In Earth years,
0:07:32 > 0:07:36how long does it take Pluto to complete an orbit around the sun?
0:07:36 > 0:07:39Have a think, have a chat.
0:07:40 > 0:07:43Write an answer down, please, Yellows.
0:07:43 > 0:07:45In years, an answer in years.
0:07:45 > 0:07:47Time's up.
0:07:47 > 0:07:49Reds, what've you got?
0:07:49 > 0:07:52How many years do you think it takes Pluto to get around the sun?
0:07:52 > 0:07:55You think 20 years to do one lap, 20 years. OK.
0:07:55 > 0:07:59Yellows, what do you think? Let's look at your answer.
0:07:59 > 0:08:04362 years, you think it takes Pluto to do one orbit of the sun.
0:08:04 > 0:08:06All right, well, it takes Pluto,
0:08:06 > 0:08:09in actual fact,
0:08:09 > 0:08:16247.92 Earth years, which means the Yellows are the winners there.
0:08:16 > 0:08:18CHEERING AND APPLAUSE
0:08:18 > 0:08:20Sorry, Reds.
0:08:21 > 0:08:23It takes Pluto much longer,
0:08:23 > 0:08:26because it's about 40 times further away from the sun than us.
0:08:26 > 0:08:30OK, that means green light lit for the Yellows, you seize control
0:08:30 > 0:08:34of the game straight away, you get the first true or false question.
0:08:34 > 0:08:39Bike reflectors sparkle in the same way as diamonds.
0:08:39 > 0:08:42Is that true or false? Have a chat before you answer.
0:08:42 > 0:08:45In the meantime, audience, let's see what you think,
0:08:45 > 0:08:47vote with your feet, is it true or false?
0:08:52 > 0:08:53I love it when this happens.
0:08:53 > 0:08:56We've split the audience in two, clean down the middle.
0:08:56 > 0:09:00- You think they do sparkle in the same way as diamonds?- Yeah.
0:09:00 > 0:09:01Yeah? Any idea why?
0:09:01 > 0:09:04Cos it's a type of metal, so it might shine the way of diamonds,
0:09:04 > 0:09:05cos it's a type of stone.
0:09:05 > 0:09:08It could be what it's made of, couldn't it? You think not?
0:09:08 > 0:09:11- No.- Any theories on that? Is it a guess, or...?
0:09:11 > 0:09:13- It's a different shape. - True, they are.
0:09:13 > 0:09:17- They're circular and they're, like, flat.- Overall, that's true.
0:09:17 > 0:09:18OK, audience, back to your places.
0:09:18 > 0:09:20Yellows, your science fact then,
0:09:20 > 0:09:23bike reflectors sparkle in the same way as diamonds.
0:09:23 > 0:09:26- Is that true or false, do you think? - True.- True.
0:09:26 > 0:09:27You think it's true.
0:09:27 > 0:09:31Oliver, bike reflectors sparkle in the same way as diamonds.
0:09:31 > 0:09:32Is that true or false?
0:09:32 > 0:09:35- HORN TOOTS - It's true, well done, Yellows!
0:09:39 > 0:09:44So, with two lights lit green you're in a good shape, well done!
0:09:44 > 0:09:47Reds, here comes your first true or false question.
0:09:47 > 0:09:50The small intestines of a human
0:09:50 > 0:09:54measure two metres long. Is that true or false?
0:09:54 > 0:09:57Have a chat, you never know, you might've picked up some...
0:09:57 > 0:09:59Any theory you've got before you answer. Think.
0:10:02 > 0:10:06The small intestines of a human measure two metres long.
0:10:06 > 0:10:08- True or false, d'you think? - False.- False.
0:10:08 > 0:10:10You think it's false. That's what you think.
0:10:10 > 0:10:13Oliver, is that true or false?
0:10:13 > 0:10:16- HORN HONKS - False, well done!
0:10:16 > 0:10:18That's a green light lit for you, you're still in.
0:10:21 > 0:10:25The average small intestine is actually six metres long,
0:10:25 > 0:10:27although it's kind of coiled up on itself,
0:10:27 > 0:10:31so it can fit neatly inside our body, or we'd be long and thin.
0:10:31 > 0:10:33It's now the Yellows' turn to feel the pressure.
0:10:33 > 0:10:34Get this one right, you win.
0:10:34 > 0:10:38Get it wrong, it's a draw and they can win on the next question.
0:10:38 > 0:10:40Here is your science fact.
0:10:40 > 0:10:44The largest organ in the human body is the brain.
0:10:44 > 0:10:46The largest organ in the human body is the brain.
0:10:46 > 0:10:50Is that true or is that false? Have a little chat and a think
0:10:50 > 0:10:54whilst we find out what the audience reckons, is it true or false?
0:10:54 > 0:10:55Vote with your feet, let's see.
0:11:01 > 0:11:03Ooh, the audience definitely thinking false here,
0:11:03 > 0:11:06apart from a few. You think that's true.
0:11:06 > 0:11:10I think someone could have a really big head and really thin body, so...
0:11:10 > 0:11:12- Yes.- It could be possible.
0:11:12 > 0:11:14So it is possible, OK, OK.
0:11:14 > 0:11:16Over here we think not, though.
0:11:16 > 0:11:18Well, I think the lungs are the biggest.
0:11:18 > 0:11:21OK. Ooh, there's some theories going on here. Do you disagree?
0:11:21 > 0:11:24- No, I agree with the lungs. - You think lungs as well?
0:11:24 > 0:11:26- Yeah. - OK, audience, back to your places.
0:11:26 > 0:11:29I think we've got a lab full of doctors going on today.
0:11:29 > 0:11:32So, the largest organ in the human body is the brain.
0:11:32 > 0:11:34Is that true or false, d'you think?
0:11:34 > 0:11:37- True.- You think it's true.
0:11:37 > 0:11:40The largest organ in the human body is the brain.
0:11:40 > 0:11:42Oliver, is that true or false?
0:11:42 > 0:11:43- HORN HONKS - It's false.
0:11:43 > 0:11:47I'm sorry, Yellows, that means a light lit for the Red Team.
0:11:47 > 0:11:50CHEERING AND APPLAUSE
0:11:51 > 0:11:56So it's not the brain. In fact, the largest human organ is the skin.
0:11:56 > 0:12:01OK, here comes your true or false question.
0:12:01 > 0:12:07A goldfish has a memory of three seconds.
0:12:07 > 0:12:08Is that true or false?
0:12:08 > 0:12:10Have a chat, have a think.
0:12:14 > 0:12:16A goldfish has a memory of three seconds.
0:12:16 > 0:12:20Is the science fact I'm giving you, is it true or false?
0:12:21 > 0:12:23- False.- You think false.
0:12:23 > 0:12:25Oliver, they think it's false.
0:12:25 > 0:12:29A goldfish has a memory of three seconds. Is it true, or is it false?
0:12:29 > 0:12:31HORN HONKS
0:12:31 > 0:12:34It is false, which means three lights are lit for the Reds,
0:12:34 > 0:12:37- well done, the girls win. - CHEERING AND APPLAUSE
0:12:39 > 0:12:41Right down to the wire.
0:12:41 > 0:12:45Scientists think goldfish may have a memory of at least three months.
0:12:45 > 0:12:49They can also spot the differences between shapes, sounds and colours,
0:12:49 > 0:12:53so they're more intelligent than my lab rats, and that's official!
0:12:53 > 0:12:56That means the third light has been lit green for the Reds,
0:12:56 > 0:12:59the Reds win this first round and they win the point.
0:12:59 > 0:13:01It's one - nil to the Reds.
0:13:17 > 0:13:19"Time travel is impossible,"
0:13:19 > 0:13:23they said. "You're messing with things you don't understand,"
0:13:23 > 0:13:27they said. "That's not how to use a soldering iron," they said.
0:13:27 > 0:13:29"I don't think it's supposed to look like that,"
0:13:29 > 0:13:33is something else they said quite a lot, but my time machine did work...
0:13:33 > 0:13:38sort of. I used it to bring my science teacher back through time
0:13:38 > 0:13:40to the Blast Lab, and it did...
0:13:40 > 0:13:43It's just she came back as a ten-year-old girl.
0:13:43 > 0:13:45I am, of course, talking about Mini Miss.
0:13:54 > 0:13:58- Hello, Miss.- I do wish you'd stuck to badminton, Richard.
0:13:58 > 0:14:00You were terrible at that too,
0:14:00 > 0:14:03but at least it's difficult to do any damage with badminton.
0:14:03 > 0:14:07Sorry, Miss, sorry, Miss. So what are we doing today, Miss?
0:14:07 > 0:14:10Well, today we're going to be learning about energy transfer
0:14:10 > 0:14:12and elasticity in a game I like to call...
0:14:15 > 0:14:18Wow! So that's what these are about, these bouncy balls. Ha ha ha!
0:14:18 > 0:14:23Ooh, I might've hit something over there, Miss, sorry! I... Ooh...
0:14:23 > 0:14:25Please don't do that, Richard.
0:14:25 > 0:14:27Yeah, Miss, sorry, Miss.
0:14:27 > 0:14:31The aim of today's experiment is to get as many bouncy footballs
0:14:31 > 0:14:34into these collecting cylinders as possible.
0:14:34 > 0:14:37I see, so they get the balls and they have to go in there, like...
0:14:37 > 0:14:39Oh, I missed, oh, I'm sorry.
0:14:39 > 0:14:41- CRASH - Oh, I've hit another one.
0:14:41 > 0:14:43I've hit another one.
0:14:43 > 0:14:46- Nothing's safe with you, is it, Richard?- Not really, Miss, no.
0:14:46 > 0:14:49The team with the most balls in their cylinders wins.
0:14:49 > 0:14:53But, the balls have to bounce at least once, or else it doesn't count.
0:14:53 > 0:14:56Oh, they have to bounce them in, so it's gotta go like tha... Oh.
0:14:56 > 0:14:58No more bouncy balls for you, Richard.
0:14:58 > 0:15:01Probably right, Miss, probably right.
0:15:01 > 0:15:04OK, well I think I understand the rules. Just a few points.
0:15:04 > 0:15:07Only balls still in the cylinder at the end that will count,
0:15:07 > 0:15:10whatever the colour. So, Reds, if you accidentally
0:15:10 > 0:15:13get one in here, that counts towards the Yellows' total.
0:15:13 > 0:15:14Does everybody understand?
0:15:14 > 0:15:18OK, teams, you have some time to get as many balls bouncing
0:15:18 > 0:15:21into these containers, and they must bounce, we will be watching.
0:15:21 > 0:15:24If they're thrown directly, they don't count.
0:15:24 > 0:15:26That some time starts... Oh, roughly...
0:15:26 > 0:15:28Er...no, exactly now!
0:15:30 > 0:15:34OK, let's get bouncing. And one straight in for the Yellows.
0:15:36 > 0:15:39Reds still getting their eye in.
0:15:42 > 0:15:45Ooh, look at that, a red ball has landed in the yellow tube,
0:15:45 > 0:15:48that'll be counted as a score for the Yellows.
0:15:50 > 0:15:53Still no joy for the Reds.
0:15:53 > 0:15:55But the Yellows get their third.
0:15:55 > 0:16:00It's not looking good for the Reds at all.
0:16:00 > 0:16:03And another one for the Yellows.
0:16:03 > 0:16:05The Yellows now up to five balls.
0:16:05 > 0:16:08The balls are bouncing, yeah, yeah, that's what they're doing,
0:16:08 > 0:16:12because the molecules inside them act a bit like a spring, like this.
0:16:12 > 0:16:14Thank you. That's what happens, a spring.
0:16:14 > 0:16:17When the balls land, they squash a little tiny bit
0:16:17 > 0:16:20and they want to return to their original shape, so they spring up.
0:16:20 > 0:16:22That means they push down,
0:16:22 > 0:16:25then we bring in the law of a certain Sir Isaac Newton...
0:16:25 > 0:16:27# Hallelujah! #
0:16:27 > 0:16:28..Blast Lab's all-time hero,
0:16:28 > 0:16:31who dictates that for every push in one direction
0:16:31 > 0:16:33there's an equal and opposite push in the other.
0:16:33 > 0:16:35So if it's pushing that way,
0:16:35 > 0:16:37it's also pushing that way, and it goes up.
0:16:37 > 0:16:40I'm going to hide, it would be best.
0:16:40 > 0:16:43Finally Reds are off the mark, and another.
0:16:43 > 0:16:46It could be too little too late, or maybe not,
0:16:46 > 0:16:50as no-one knows when "some time" could be up.
0:16:50 > 0:16:53However, I think the Yellows look to have done enough already.
0:16:56 > 0:17:00AUDIENCE: Three, two, one...
0:17:00 > 0:17:04OK. Time is up.
0:17:04 > 0:17:07Right, let's have the big add up.
0:17:07 > 0:17:09For the Yellow Team, how many do we have?
0:17:09 > 0:17:15Six. Did they all bounce in? So that's six for the Yellows.
0:17:15 > 0:17:18For the Reds, what've we got?
0:17:18 > 0:17:21Two. Oh, dear, did they all bounce in?
0:17:21 > 0:17:24So they all count, but it's not enough cos that means
0:17:24 > 0:17:26that the Yellows win and that takes the score to one all.
0:17:30 > 0:17:33OK, all this excitement has made me hungry.
0:17:33 > 0:17:35Lab rats, chips, please, where are my chips?
0:17:35 > 0:17:38Ah, thank you very much. Where's the salt?
0:17:38 > 0:17:40I need salt on these. Go on, go away, go and get some salt.
0:17:40 > 0:17:43Thank you. Tell you what else I fancy, an experiment...
0:17:43 > 0:17:46with a lot of salt, as well, while we're at it.
0:17:46 > 0:17:48In fact, tons of it.
0:17:50 > 0:17:53Meet intrepid explorer, Ferdinand Magellan.
0:17:53 > 0:17:57He's travelled the globe in search of adventure and riches,
0:17:57 > 0:18:00but all he brought back was a tropical disease
0:18:00 > 0:18:03which has led to him growing a pair of wings.
0:18:04 > 0:18:08Stuck-on fairy-wingy-itis. Nasty!
0:18:08 > 0:18:11The only cure - a swim in the Dead Sea.
0:18:11 > 0:18:14Its high salt content will wash away this winged curse.
0:18:14 > 0:18:18Unfortunately, he's broke, so he can't travel there himself.
0:18:18 > 0:18:24His only hope is to recreate the Dead Sea conditions
0:18:24 > 0:18:25here in this swimming pool.
0:18:26 > 0:18:29To aid Ferdinand in his quest to find a cure,
0:18:29 > 0:18:33he's turned to his trusty sidekick, McQuack.
0:18:33 > 0:18:37McQuack has been filled with just enough sand to make him sink in
0:18:37 > 0:18:42fresh water, but, if we add enough salt, the duck will float once more.
0:18:42 > 0:18:46Hang on a second, that doesn't sound right. I think we need an animation.
0:18:47 > 0:18:50For an object to float on a liquid, the liquid must be more dense than
0:18:50 > 0:18:53the whole of the object and the air contained within it.
0:18:53 > 0:18:57In normal water, its particles are spread out, so it's not that dense.
0:18:57 > 0:19:02At first, the water is less dense than McQuack, which is why he sinks.
0:19:02 > 0:19:06But if we add salt, the water increases in density, eventually
0:19:06 > 0:19:12becoming more dense than McQuack, so he can now rise to the surface.
0:19:12 > 0:19:15But our experiment relies on the salt actually dissolving
0:19:15 > 0:19:19into the water, and also on the duck being watertight.
0:19:19 > 0:19:22So will the salty plan work and make McQuack rise to the surface?
0:19:22 > 0:19:26Hold the experiment right there! There is another point up for grabs,
0:19:26 > 0:19:28It goes the team who can tell me...
0:19:28 > 0:19:34will it work? Now, bearing in mind there are some lab rats involved,
0:19:34 > 0:19:38will McQuack rise to the surface or stay at the bottom of the pool
0:19:38 > 0:19:40when the salt is added?
0:19:40 > 0:19:42Have a chat, have a think, teams.
0:19:45 > 0:19:48Reds, what d'you think? Will it or won't it work?
0:19:48 > 0:19:51- ALL: We think it'll float. - You think it will. Yellows?
0:19:51 > 0:19:53We think it'll float too.
0:19:53 > 0:19:54Both teams think it's going to work.
0:19:54 > 0:19:58That's quite touching that both teams have come here to my Blast Lab
0:19:58 > 0:20:01and had enough faith in my lab rats to think they'll get it right.
0:20:01 > 0:20:02Maybe they will.
0:20:02 > 0:20:05Only one way to find out... carry on with the experiment.
0:20:07 > 0:20:09Ferdinand Magellan has travelled the world
0:20:09 > 0:20:12and come back with a strange tropical disease.
0:20:12 > 0:20:16Only a dunk in water salty enough to make his duck float will cure him.
0:20:16 > 0:20:19Yeah, I know, long story, had to be there.
0:20:19 > 0:20:21But will we be able to add enough salt to make the duck float?
0:20:21 > 0:20:23Let's find out.
0:20:23 > 0:20:28Ok, so we're going to add salt to the swimming pool bag by bag.
0:20:28 > 0:20:30Here we go. Bag number one.
0:20:30 > 0:20:33Nope, no change yet.
0:20:33 > 0:20:35Ok, that's two.
0:20:36 > 0:20:37This could take a while.
0:20:37 > 0:20:41where's the remote control, we've got no time for this.
0:20:41 > 0:20:43OK...
0:20:43 > 0:20:46Right, here we go, much better, 46 bags now, things are looking good.
0:20:46 > 0:20:50Hang on a minute, it's slowed down, what's going on? Yeah, very helpful.
0:20:52 > 0:20:55They've been at it for hours now,
0:20:55 > 0:20:59bag after bag. Surely soon we'll see the results of their hard work.
0:20:59 > 0:21:03I mean all they're asking was for a duck to float in water.
0:21:03 > 0:21:08Bag after bag after bag has been emptied into the pool.
0:21:08 > 0:21:09This should've been enough,
0:21:09 > 0:21:12but there's no movement in the water and no sign of McQuack.
0:21:12 > 0:21:16The stillness of the water says it all, a combination of not stirring
0:21:16 > 0:21:23their salt solution properly and McQuack taking on water has led to this...
0:21:23 > 0:21:28Abject failure. Perhaps predictably, it didn't work,
0:21:28 > 0:21:32that means no points to either team, I'm sorry.
0:21:32 > 0:21:34The lab rats let us down there, not the science,
0:21:34 > 0:21:36because it might've stood a chance
0:21:36 > 0:21:39if the lab rats had remembered to stir the salt
0:21:39 > 0:21:43and dissolve it all into the water to make the salt solution.
0:21:43 > 0:21:44However, they didn't.
0:21:44 > 0:21:48They also left a hole in the duck so it filled with water,
0:21:48 > 0:21:50and became even heavier,
0:21:50 > 0:21:53so it was even harder than if they'd done it right in the first place.
0:21:53 > 0:21:57That means the score remains the same - one all to Yellows and Reds.
0:21:57 > 0:21:59It is now time for...
0:22:03 > 0:22:06Oh, yeah. Starring, my Snot Bots.
0:22:06 > 0:22:08Yeah, one of my most magnificent creations.
0:22:08 > 0:22:10The plan, of course,
0:22:10 > 0:22:12is for them one day to replace all of my lab rats.
0:22:12 > 0:22:16They're brilliant, they have artificial human intelligence...
0:22:16 > 0:22:18very human. As a result, they have now started taking on
0:22:18 > 0:22:21human characteristics like dancing badly at weddings,
0:22:21 > 0:22:26over-sleeping, and they've all caught colds, hence...the snot.
0:22:26 > 0:22:28Yuck! There is a cure.
0:22:28 > 0:22:31We have special medicinal discs, they're hidden in the septic tank.
0:22:31 > 0:22:34All you teams have to do is feed them those discs
0:22:34 > 0:22:36and you will cure them of their colds.
0:22:36 > 0:22:38Those discs also represent prizes.
0:22:38 > 0:22:40Today they include a heart rate monitor,
0:22:40 > 0:22:42a radio-controlled spider and a scooter.
0:22:42 > 0:22:46Teams, whichever one of you, Reds, Yellows, gets the most prize discs
0:22:46 > 0:22:50into the Snot Bot will win the prizes written on those discs!
0:22:50 > 0:22:53What happens to the other team we won't talk about right now,
0:22:53 > 0:22:55but they won't be taking their prizes home.
0:22:55 > 0:22:58Just a couple of notes, you will see, as well as the prize discs,
0:22:58 > 0:23:01in there, there are these, red and yellow herrings.
0:23:01 > 0:23:03Get one of these into the Snot Bot by accident,
0:23:03 > 0:23:05you will lose a prize disc.
0:23:05 > 0:23:09That means you could lose the whole game, so be careful.
0:23:09 > 0:23:12Good luck, teams, there's no head start cos it is a draw.
0:23:12 > 0:23:17Both teams have some time to get as many prize discs into their waiting
0:23:17 > 0:23:21Snot Bot as they possible can, and that some time's going to start...
0:23:21 > 0:23:22Ooh, I'd say...let's think...
0:23:22 > 0:23:23Now!
0:23:23 > 0:23:29Away we go with both teams trudging through terrible robot snot.
0:23:29 > 0:23:33Unfortunately the bots are suffering from a particularly bad cold,
0:23:33 > 0:23:35so the snot is... Well, very thick.
0:23:35 > 0:23:39However, the Reds have got a disc and in it goes.
0:23:39 > 0:23:42Both teams now shoulder-deep in the green stuff.
0:23:42 > 0:23:49Another disc for the Reds but, ooh no, one's missed the robot's mouth.
0:23:50 > 0:23:52But it looks like Plum is going to get another chance.
0:23:52 > 0:23:56Taking her time, this time no mistakes, there you go.
0:23:58 > 0:24:02Yellows not having an easy time of foraging in the snot.
0:24:02 > 0:24:04Come on!
0:24:06 > 0:24:11But no such trouble for the Reds with their third going in.
0:24:11 > 0:24:14The Yellows have to hurry if they want to avoid having the honour
0:24:14 > 0:24:18of being the first team on Blast Lab not to score at all
0:24:18 > 0:24:20in a Messy Messy Mess Test.
0:24:23 > 0:24:27AUDIENCE: Four, three, two, one...
0:24:32 > 0:24:35I think the... Yeah, the bot snot is particularly thick today,
0:24:35 > 0:24:37it's not nice in there.
0:24:37 > 0:24:39Let's see the scores and find out who's won.
0:24:39 > 0:24:43How many do we have for the Red Team? Let's have a look.
0:24:43 > 0:24:47Three prize discs for the Reds. For the Yellows, what've we got?
0:24:47 > 0:24:50None, no prizes, that means it is a win for the Reds.
0:24:50 > 0:24:51CHEERING AND APPLAUSE
0:24:51 > 0:24:53Let's find out what you've won.
0:24:53 > 0:24:58Ninja Nan, are you ready? Yoyo, for each of you, you've won already.
0:24:58 > 0:24:59A scooter for each of you.
0:24:59 > 0:25:01A puzzle cube.
0:25:02 > 0:25:05Now, Yellows, normally at this point we get the pleasure,
0:25:05 > 0:25:09you have the misery of us looking through what you would've won.
0:25:09 > 0:25:12This time we're not going to do that, but don't worry,
0:25:12 > 0:25:13we'll come up with something,
0:25:13 > 0:25:15because it is time for Bidet Goes Bang.
0:25:22 > 0:25:25Reds... Wow!
0:25:25 > 0:25:27What a haul of prizes, well done, Reds.
0:25:27 > 0:25:31All of that coming home with you, well played from the beginning.
0:25:31 > 0:25:34Good work. Over here, it's slightly more... Yellows...
0:25:34 > 0:25:37Hi, didn't go well for you, that last game, did it?
0:25:37 > 0:25:40The difficult thing is, cos you didn't get any prize discs,
0:25:40 > 0:25:41no prizes to blow up.
0:25:41 > 0:25:44We won't let a little thing like that beat us on Blast Lab.
0:25:44 > 0:25:47Come here, lab rat, please, because what we do,
0:25:47 > 0:25:51if you win no prizes, we give you a goody bag full of wonderful things.
0:25:51 > 0:25:54There's a Blast Lab pen and ruler, here you go, hold those for me,
0:25:54 > 0:25:56please, and you get...
0:25:56 > 0:25:59There's an old pair of pants here, you get that, there's...
0:25:59 > 0:26:03Oh, there's just wonder... Look... look at that, a slipper,
0:26:03 > 0:26:07You actually get a slipper and half a banana. I know.
0:26:07 > 0:26:10Obviously that gives us the opportunity to blow it up.
0:26:10 > 0:26:12Put it all back in, lab rat, take it away,
0:26:12 > 0:26:15because it's time for the walk of shame.
0:26:15 > 0:26:16Come with me, chaps.
0:26:19 > 0:26:21- Aah!- I know, it's sad. Yep.
0:26:21 > 0:26:26The one thing they had, the one thing they could take,
0:26:26 > 0:26:29Yeah, yup, yup, yup, yup...
0:26:30 > 0:26:32Here it is, the plunger.
0:26:34 > 0:26:36Yeah.
0:26:36 > 0:26:39So, we've found something to give you, and then blow up.
0:26:39 > 0:26:42If you'd like to lift the plunger, please, Yellows.
0:26:42 > 0:26:46If we're ready, audience, let's count 'em down from five.
0:26:46 > 0:26:48- Five, four, three, two, one. - Five, four, three, two, one.
0:26:48 > 0:26:51CHEERING AND APPLAUSE
0:26:54 > 0:26:58Great. That feels good, for me! Maybe not for you.
0:26:58 > 0:27:01OK. We've spent a lot of time looking at food today,
0:27:01 > 0:27:05and I'm off now to spend a bit more time looking at it before eating it.
0:27:05 > 0:27:07Lab rats, where's my dinner?
0:27:07 > 0:27:09Until next time...goodbye.
0:27:09 > 0:27:11CHEERING AND APPLAUSE
