0:00:33 > 0:00:37Hello, hello, and welcome to my Blast Lab.

0:00:37 > 0:00:38CHEERING AND APPLAUSE

0:00:38 > 0:00:41Thank you. Thank you.

0:00:41 > 0:00:43I should say it was originally supposed to be called

0:00:43 > 0:00:47my Super Safe Experiment Lab, but I got told off for false advertising.

0:00:47 > 0:00:51Apparently Blast Lab is more "factually accurate."

0:00:51 > 0:00:53Anyway, joining me today are the UK's greatest

0:00:53 > 0:00:56up-and-coming scientists who will compete for amazing prizes

0:00:56 > 0:00:59whilst helping me with some incredibly safe experiments.

0:00:59 > 0:01:02Coming up, Oliver's all-powerful Fact Nav 2.0

0:01:02 > 0:01:04is here to filter facts from fiction.

0:01:08 > 0:01:11In Mini Science, it's raining eggs.

0:01:15 > 0:01:18The long-ranging war between jelly and cornstarch is settled

0:01:18 > 0:01:20once and for all, with an explosive experiment.

0:01:24 > 0:01:28And pieces mean prizes in the one and only Bridge Of Destiny.

0:01:28 > 0:01:32The Bridge Of Destiny.

0:01:32 > 0:01:33Today's a special day

0:01:33 > 0:01:37because Ninja Nan is entertaining her colleagues from the Cobra Squad.

0:01:45 > 0:01:49These ladies are the toughest elite squad of fighters in the world.

0:01:49 > 0:01:51They're nimble, silent and lethal.

0:01:51 > 0:01:54Believe me, you don't wanna be near them when things kick off.

0:01:54 > 0:01:57They're like one big coiled spring. Let's take a look at them.

0:01:57 > 0:01:59Ah, it looks like it's nap time.

0:01:59 > 0:02:03If there's the slightest hint of danger, they'll be right into it.

0:02:03 > 0:02:06Let's have a look at who's trying to get into my lab today.

0:02:06 > 0:02:11Hold on, hold on, that's not a team of players, that is a yeti!

0:02:11 > 0:02:14This is a massive breach of security!

0:02:14 > 0:02:17I'm going to break out Ninja Nan and the Cobra Squad. Attack!

0:02:17 > 0:02:19Oh, they've already sorted it out.

0:02:19 > 0:02:21I feel embarrassed about using this now.

0:02:21 > 0:02:23Thank you very much.

0:02:23 > 0:02:27Let's meet the real bunch of people trying to get into my lab today.

0:02:31 > 0:02:33Ah, that's more like it, actual people.

0:02:33 > 0:02:36Yes, come forwards, mind the yeti. Long story, don't worry.

0:02:36 > 0:02:39Now, you claim to be the red team, yeah? Can't be too sure.

0:02:39 > 0:02:42Identify yourselves by name. You are?

0:02:42 > 0:02:44- Lauren.- Dionne.- Mia.

0:02:44 > 0:02:46Yeah, I've got that written down here.

0:02:46 > 0:02:49Under hidden talent, who's gonna do what for us?

0:02:49 > 0:02:51We're gonna do dancing.

0:02:51 > 0:02:53That's what it says here. Well, good luck, girls, go on.

0:02:55 > 0:02:57OK, yeah. What is this, like...?

0:02:57 > 0:03:00Ooh, look at that. You see. Oh. OK.

0:03:00 > 0:03:04Fair enough, that's some dancing, that'll do. Come into the lab.

0:03:04 > 0:03:07APPLAUSE AND CHEERING

0:03:10 > 0:03:12Fair enough, no further than that,

0:03:12 > 0:03:14because Ninja Nan's got her eyes on you.

0:03:14 > 0:03:16You're more or less through security, one final check.

0:03:16 > 0:03:19We agreed a password with the real red team.

0:03:19 > 0:03:21Pizza.

0:03:21 > 0:03:22That's what I've got. Why?

0:03:22 > 0:03:25Because when I was little, I put pizza in the cupboard

0:03:25 > 0:03:27and then six years later my sister found it.

0:03:27 > 0:03:29OK, well, good luck in the lab.

0:03:29 > 0:03:32Get settled in for the first game. That is your red team.

0:03:32 > 0:03:34We have a red team.

0:03:35 > 0:03:38What we need now is a yellow team.

0:03:38 > 0:03:40Let's meet three people who claim to be them.

0:03:47 > 0:03:50Hello, step forwards, mind the yeti, mind the yeti.

0:03:50 > 0:03:53Please, come forwards. Sorry about that. Long, long story.

0:03:53 > 0:03:56You claim to be the yellow team. Identify yourselves. You are?

0:03:56 > 0:03:59- Benjamin.- Nathaniel.- Joshua.

0:03:59 > 0:04:01Benjamin, Nathaniel, Joshua.

0:04:01 > 0:04:03That's what I've got written down.

0:04:03 > 0:04:06Joshua, I have your name next to talent. What are you gonna do?

0:04:06 > 0:04:09- I can do sign language. - Really? Go on, then.

0:04:15 > 0:04:16And what did that say?

0:04:16 > 0:04:18My name is Joshua.

0:04:18 > 0:04:20I've no idea, so I'll let you in.

0:04:20 > 0:04:23Please come into the lab. Come into the lab.

0:04:23 > 0:04:25APPLAUSE AND CHEERING

0:04:27 > 0:04:29Hello, you three, nice to see you. Welcome to the lab.

0:04:29 > 0:04:32One last security check, lads, before I let you into the lab.

0:04:32 > 0:04:35We agreed a password with the real yellow team,

0:04:35 > 0:04:38you would know that if you are them. What is the password?

0:04:38 > 0:04:40Sleepover.

0:04:40 > 0:04:42That's what I've got. Why sleepover?

0:04:42 > 0:04:46Because in year four we had a sleepover and it was rubbish.

0:04:46 > 0:04:48What, not like cakes and staying up late and just...?

0:04:48 > 0:04:51OK, fair enough then, lads.

0:04:51 > 0:04:53Get settled in ready for the first game.

0:04:53 > 0:04:56They are your yellow team.

0:04:56 > 0:05:00One more thing to do. It's time to introduce everybody's dream car,

0:05:00 > 0:05:02assuming everybody dreams of a worn-out old banger

0:05:02 > 0:05:05that is super-intelligent. It is, of course, Oliver!

0:05:25 > 0:05:29Come here, come in. Hello. Get you connected up.

0:05:29 > 0:05:32There you go, system is up and running.

0:05:32 > 0:05:36I have just upgraded Oliver with the latest Fact Nav version 2.0.

0:05:36 > 0:05:37It's brilliant. Well...

0:05:37 > 0:05:40it would be, but, you see, I bought the software

0:05:40 > 0:05:45from a dodgy-looking bloke at a car boot sale, which means two things.

0:05:45 > 0:05:49Firstly, I've learnt my lesson about buying from reputable dealers,

0:05:49 > 0:05:53and secondly, not all the facts in it are correct.

0:05:53 > 0:05:56So we're going to need some help sorting fact from fiction.

0:05:56 > 0:05:59That, teams, is down to you, so I'll give you science facts,

0:05:59 > 0:06:01you tell me if they're true or false.

0:06:01 > 0:06:05Oliver will let us know. If they are true, he'll do this.

0:06:05 > 0:06:06HORN BEEPS

0:06:06 > 0:06:10And if the fact is false he'll let us know by doing this.

0:06:10 > 0:06:12FOGHORN SOUNDS

0:06:12 > 0:06:14Here's how it works. Three lights on either side,

0:06:14 > 0:06:16at the moment all three are lit red.

0:06:16 > 0:06:18Every time a team gives me a correct answer,

0:06:18 > 0:06:21we'll light one of your lights green.

0:06:21 > 0:06:24The first team to get all three lights lit green wins.

0:06:24 > 0:06:26Great! Apart from one thing.

0:06:26 > 0:06:29If you answer a question incorrectly,

0:06:29 > 0:06:33we'll light one of the other team's lights green,

0:06:33 > 0:06:35so there's danger of winning the game for the other side.

0:06:35 > 0:06:37The first question is important,

0:06:37 > 0:06:40because this is the question that gives a team the chance

0:06:40 > 0:06:42to seize control of the game, OK?

0:06:42 > 0:06:44This is a nearest to question.

0:06:44 > 0:06:48I just need the answer nearest to the real one.

0:06:48 > 0:06:49OK, it is this,

0:06:49 > 0:06:52the first artificial satellite was called Sputnik One

0:06:52 > 0:06:57and was launched by the Russians, but in what year was it launched?

0:06:57 > 0:07:00Both teams writing answers down, that's a good sign.

0:07:00 > 0:07:04Remember the green light is lit for the team closest to the answer.

0:07:04 > 0:07:06Are we ready?

0:07:09 > 0:07:11Everybody got an answer written down?

0:07:11 > 0:07:14Yellows, let's have a look, what have you got? 1996.

0:07:14 > 0:07:16OK. Reds, what've you got?

0:07:16 > 0:07:211853. There is some disparity between the two answers there,

0:07:21 > 0:07:23quite a lot in fact.

0:07:23 > 0:07:28OK, well, the real answer is 1957,

0:07:28 > 0:07:33which means the yellows are closest, despite being quite a long way away!

0:07:33 > 0:07:37Well done. Sorry reds. Tricky one.

0:07:37 > 0:07:40This was the first man-made satellite to orbit the Earth.

0:07:40 > 0:07:42Yellows, you get the first true or false.

0:07:42 > 0:07:45You've got a green light lit, and you've seized control of the game.

0:07:45 > 0:07:48Here comes your true or false question.

0:07:48 > 0:07:52There was a Frenchman who ate 900 grams of metal a day.

0:07:52 > 0:07:53True or false?

0:07:53 > 0:07:57Audience, vote with your feet, is it true or false?

0:07:59 > 0:08:02Ooh, there's some mind-changing going on,

0:08:02 > 0:08:04there's a drift from true across to false.

0:08:04 > 0:08:07- Are you sticking with true? - Yeah, definitely.

0:08:07 > 0:08:10- Are you on true just cos there was no room left on false?- No.

0:08:10 > 0:08:12No. What do you think, then?

0:08:12 > 0:08:15I read a book once, and it said that there was Frenchman

0:08:15 > 0:08:18who ate 900 grams, but I don't think it said every day.

0:08:18 > 0:08:20I'd say. That's quite a chunk of metal,

0:08:20 > 0:08:23that's like a big chunk of a bicycle every day.

0:08:23 > 0:08:26All right, well, audience, we've no idea, is the truth.

0:08:26 > 0:08:27Back to your places,

0:08:27 > 0:08:31cos you're not playing for the point, that's the teams.

0:08:31 > 0:08:33There was a man who ate 900 grams of metal a day,

0:08:33 > 0:08:35is that true or false?

0:08:35 > 0:08:37False.

0:08:37 > 0:08:40False? Oliver, do let us know, is that true or false?

0:08:40 > 0:08:42HORN BEEPS

0:08:42 > 0:08:44I'm sorry, it's true. Sorry, yellows.

0:08:44 > 0:08:48That means there's a green light lit for the reds. See what I mean?

0:08:51 > 0:08:55It was bloke called Michel Lotito from Grenoble in France.

0:08:55 > 0:08:58He started off in 1959 eating glass, as you do.

0:08:58 > 0:09:00Gastroenterologists described his ability

0:09:00 > 0:09:03to consume 900 grams of metal a day as "unique".

0:09:03 > 0:09:07Right, reds, this is your true or false question.

0:09:07 > 0:09:10Air pressure can push against the human body

0:09:10 > 0:09:14with a force equivalent to the weight of a small car.

0:09:14 > 0:09:17Air pressure can push a human body with the force equivalent

0:09:17 > 0:09:19to the weight of a small car.

0:09:19 > 0:09:21Is that, do you think, true or false?

0:09:21 > 0:09:24- True.- You think true?

0:09:24 > 0:09:27Oliver, is that true or false?

0:09:27 > 0:09:29HORN BEEPS

0:09:29 > 0:09:32That's two lights lit green for the reds, well done!

0:09:36 > 0:09:40Right, yellows. Here is your science fact.

0:09:40 > 0:09:45A giraffe has double the number of neck bones a human has.

0:09:45 > 0:09:50A giraffe has double the number of neck bones a human has.

0:09:50 > 0:09:52Is that true or false, do you think?

0:09:52 > 0:09:53- True.- You think it's true?

0:09:53 > 0:09:57Oliver, a giraffe has double the number of neck bones a human has.

0:09:57 > 0:10:00Is that true or is that false?

0:10:00 > 0:10:01FOGHORN SOUNDS

0:10:01 > 0:10:05That means it's false, which means a green light is lit for the reds.

0:10:05 > 0:10:07I'm really sorry.

0:10:09 > 0:10:13In actual fact, they have the same number as us, seven.

0:10:13 > 0:10:17It's just obviously they're a lot bigger in the case of a giraffe.

0:10:17 > 0:10:19All of which means, at the end of the first game,

0:10:19 > 0:10:22the score now is 1-0 to the reds. Well done, well done.

0:10:37 > 0:10:43Now, I'm not saying I'm clever, that's for other people to do.

0:10:43 > 0:10:46But I did invent a time machine,

0:10:46 > 0:10:50which is the sort of thing a very clever person would do.

0:10:50 > 0:10:53Unfortunately, I did then spill my milkshake in it,

0:10:53 > 0:10:56which is the sort of thing a very silly person would do,

0:10:56 > 0:10:59and as a result my experiment in time travel went a bit wrong.

0:10:59 > 0:11:02I did succeed in bringing my old science teacher back

0:11:02 > 0:11:05through time, but she came back as a young girl.

0:11:05 > 0:11:07She is, of course, Mini Miss!

0:11:14 > 0:11:16Hello, Miss. Hello. Hello, Miss.

0:11:16 > 0:11:19So, Richard, are you anywhere near to fixing that time machine

0:11:19 > 0:11:21so I can finally go home?

0:11:21 > 0:11:23Ah, well, yeah, bit of a problem with that.

0:11:23 > 0:11:26You see, the thing is, I put it in a safe place

0:11:26 > 0:11:29- so the government couldn't find it. - Why is that a problem?

0:11:29 > 0:11:31I forgot where it was.

0:11:31 > 0:11:34Sorry, Miss, sorry. Anyway, today's game, what are we doing?

0:11:34 > 0:11:37- We will talk about that again later. - Yes, I'm sorry, Miss.

0:11:37 > 0:11:40- Today, we're looking at air resistance.- Bear resistance?!

0:11:40 > 0:11:43- Air resistance, Richard, don't be ridiculous.- Sorry.

0:11:43 > 0:11:44Today's game is called...

0:11:46 > 0:11:50- Wow!- Our two teams will drop eggs from the balcony

0:11:50 > 0:11:51with parachutes attached.

0:11:51 > 0:11:55Right, so our teams have to attach these parachutes -

0:11:55 > 0:11:58OK, thank you - on to the egg.

0:11:58 > 0:12:01They pass them to their team-mate on the balcony,

0:12:01 > 0:12:03who has to throw them off again.

0:12:03 > 0:12:06Now, if the egg lands in the yolk, there, they get two points.

0:12:06 > 0:12:11If it lands in the white, one point. And if it cracks, no points.

0:12:11 > 0:12:14- Very good, Richard. - Yeah, and no bears? OK.

0:12:14 > 0:12:18Right, well, we all know what we've got to do, if we're all ready?

0:12:18 > 0:12:21Get as many eggs into the yolk as you can without breaking them.

0:12:21 > 0:12:24Good luck, teams. Here we go, your time starts,

0:12:24 > 0:12:27ooh, I dunno, let's say NOW!

0:12:27 > 0:12:29KLAXON SOUNDS

0:12:29 > 0:12:32And they're off, beginning the fiddliest part

0:12:32 > 0:12:34of this most serious of mini sciences.

0:12:34 > 0:12:37The teams are focused and the crowd excited,

0:12:37 > 0:12:41whilst hens throughout the Home Counties look on

0:12:41 > 0:12:44in a mixture of dread and hateful anticipation.

0:12:44 > 0:12:47With parachutes attached, the first batch of eggs

0:12:47 > 0:12:49are hoisted aloft to face their fate.

0:12:51 > 0:12:55Here we go, they throw in unison and smash in much the same way, as well.

0:12:55 > 0:12:57Ah, well, onwards and upwards.

0:12:57 > 0:13:01And then downwards again, of course, very quickly.

0:13:01 > 0:13:03Both teams have production lines,

0:13:03 > 0:13:05nothing free range about this operation.

0:13:05 > 0:13:09More eggs are thrown, and I think one may have survived.

0:13:09 > 0:13:12Too hard to tell, but it is raining eggs out there

0:13:12 > 0:13:14so all to play for.

0:13:17 > 0:13:19It might surprise you,

0:13:19 > 0:13:22but parachutes were first invented about 500 years ago.

0:13:22 > 0:13:24I guess they had to wait a few hundred years

0:13:24 > 0:13:28before planes were invented so they could actually use them.

0:13:28 > 0:13:32But the way they work is by giving falling objects a larger area.

0:13:32 > 0:13:35As our eggs fall, gravity is pulling them towards the ground.

0:13:35 > 0:13:37But there's a force known as air resistance

0:13:37 > 0:13:39that's pushing the other way.

0:13:39 > 0:13:41So if we can make the area of the falling egg bigger

0:13:41 > 0:13:43by attaching a parachute,

0:13:43 > 0:13:45there's more area for the air resistance to act on,

0:13:45 > 0:13:48pushing up, which means it'll slow down the egg's fall.

0:13:48 > 0:13:52Eggstraordinary. Huh, huh, thank you!

0:13:52 > 0:13:55Apologies for the gag. The teams aren't laughing,

0:13:55 > 0:13:59there's a job to be done and not much some time left to do it.

0:14:03 > 0:14:06The floor now layered with the best efforts of yellows and reds alike.

0:14:06 > 0:14:11Only a fool or a lab rat would try and predict the final result

0:14:11 > 0:14:12at this point.

0:14:16 > 0:14:19KLAXON SOUNDS

0:14:19 > 0:14:21The time is up.

0:14:21 > 0:14:23Both teams working very, very hard there.

0:14:23 > 0:14:25We must now do the big add up.

0:14:25 > 0:14:27Two points for eggs landing on the yolk,

0:14:27 > 0:14:29one for eggs landing on the white,

0:14:29 > 0:14:32none for eggs landing anywhere else or getting cracked.

0:14:32 > 0:14:34Let's do the big add up.

0:14:34 > 0:14:39So, for the red team we have a total of four points.

0:14:39 > 0:14:42Yellows, we have a total of ten points,

0:14:42 > 0:14:44which means the yellows take it.

0:14:44 > 0:14:46Well done, well done, teams,

0:14:46 > 0:14:49using that air resistance to fight gravity.

0:14:51 > 0:14:55So we've seen how you can defy gravity using air resistance.

0:14:55 > 0:14:57Maybe you've wondered how to make the most of gravity?

0:14:57 > 0:15:00Have you? No? Are you sure? Definitely not.

0:15:00 > 0:15:04Never mind, because we've done the experiment anyway, and here it is.

0:15:04 > 0:15:09Every year, Ninja Nan and her age-old, old-age superhero friends

0:15:09 > 0:15:13go off together on the annual Super Women's Institute coach tour

0:15:13 > 0:15:14of the Cotswolds.

0:15:14 > 0:15:16Well, we think it's the Cotswolds they go to,

0:15:16 > 0:15:19it's difficult to tell, because it's a Ninja coach,

0:15:19 > 0:15:23so it's completely undetectable to the naked eye, ear, radar,

0:15:23 > 0:15:27or any sort of recording equipment, including television cameras.

0:15:27 > 0:15:30Last year, a reporter from the local Cotswolds News

0:15:30 > 0:15:33thought he caught the tour coach going past.

0:15:35 > 0:15:37I'm not so sure.

0:15:37 > 0:15:41I think there's more chance of a yeti walking behind me right now,

0:15:41 > 0:15:43and me not even noticing.

0:15:43 > 0:15:48Anyway, Nan's planning on joining her friends again this year,

0:15:48 > 0:15:51so she needed to arrange for someone to cover security for her

0:15:51 > 0:15:53while she's gone.

0:15:53 > 0:15:56Nan being Nan, she has to do things her own way,

0:15:56 > 0:15:58so rather than put an advert in the local paper,

0:15:58 > 0:16:03she decided to launch a full-scale televised national campaign

0:16:03 > 0:16:06to find the country's best undiscovered superhero.

0:16:06 > 0:16:09And now, after months of tedious auditions,

0:16:09 > 0:16:13she's whittled the candidates down to the final two.

0:16:15 > 0:16:18For the first finalist, dreams of a summer job guarding my lab

0:16:18 > 0:16:20seemed a million miles away.

0:16:20 > 0:16:25Karen Quarterwit is a tear duct technician from East Anglia.

0:16:25 > 0:16:30She works to fund her dream of becoming a superhero.

0:16:32 > 0:16:36But her real passion in life is jelly.

0:16:36 > 0:16:40She eats jelly, drinks jelly and even makes jelly sculptures.

0:16:40 > 0:16:43Karen's dream is for her alter ego to make it big

0:16:43 > 0:16:47and move on to superhero work full-time.

0:16:47 > 0:16:50Karen Quarterwit.

0:16:50 > 0:16:52Jelly Woman.

0:16:53 > 0:16:57So, let's meet our next contestant, Colby Cobb.

0:16:57 > 0:17:01After twisting his ankle playing a game of hide and seek

0:17:01 > 0:17:06on his parents' farm, Colby was helped by a family of corn,

0:17:06 > 0:17:10who took him into their crop and showed him the way...

0:17:11 > 0:17:13..of the corn.

0:17:13 > 0:17:16# You raise me up

0:17:16 > 0:17:21# So I can stand on mountains... #

0:17:21 > 0:17:24There's no-one in the world more corny than Colby.

0:17:24 > 0:17:26In fact, this whole story is corny.

0:17:26 > 0:17:28So is the music, actually. Who picked that?

0:17:28 > 0:17:31Enough already. Let's get on with the excitement.

0:17:32 > 0:17:35More like it. The rules are simple.

0:17:35 > 0:17:38One crane, two competitors,

0:17:38 > 0:17:41each with a bag of the source of their super powers.

0:17:41 > 0:17:47Jelly Woman has bag of her most precious strawberry jelly.

0:17:47 > 0:17:52Whilst Corn Man is mixing up a concoction of cornstarch and water.

0:17:52 > 0:17:56Our wannabe superheroes will take it in turn to drop their bags

0:17:56 > 0:18:0030 metres from the crane to see which will cause the most damage

0:18:00 > 0:18:02to the paving slabs below.

0:18:02 > 0:18:05We all know jelly is wobbly.

0:18:05 > 0:18:08This is because it's halfway between a liquid and a solid,

0:18:08 > 0:18:10what scientists call a colloid.

0:18:10 > 0:18:12It's make up of long chains of solid proteins

0:18:12 > 0:18:15with liquid water trapped in the spaces between,

0:18:15 > 0:18:19whereas corn starch and water is different.

0:18:19 > 0:18:22It's what scientists call a non-Newtonian fluid.

0:18:22 > 0:18:26This means it can change from acting like a liquid when poured,

0:18:26 > 0:18:28to being like a solid when hit.

0:18:28 > 0:18:31But today we will find out, once and for all time,

0:18:31 > 0:18:33who is the strongest, and that winner will be crowned

0:18:33 > 0:18:38Britain's best ultimate new superhero talent person thing.

0:18:38 > 0:18:40They'll get a badge, or something.

0:18:40 > 0:18:42OK, so here we go.

0:18:42 > 0:18:44Jelly Woman is first up.

0:18:44 > 0:18:48Let's hoist her jelly bag to 30 metres.

0:18:48 > 0:18:50Now it does take a while, this crane.

0:18:50 > 0:18:53At least I'm not standing in the rain, they are.

0:18:53 > 0:18:55OK, it's ready.

0:18:55 > 0:18:58Let's start the countdown as it looks really cold out there.

0:18:58 > 0:19:01In fact, is that sleet? Yeah, that's sleet.

0:19:01 > 0:19:05OK, five, four, three...

0:19:05 > 0:19:07Oh, hang on a second, we haven't asked the question.

0:19:07 > 0:19:11Which will do more damage to the paving stones,

0:19:11 > 0:19:13the jelly or the corn starch?

0:19:13 > 0:19:16You stay out here in this wonderful British summer,

0:19:16 > 0:19:17whilst I ask the teams in the studio.

0:19:17 > 0:19:21OK, well, I don't think we should worry about them too much.

0:19:21 > 0:19:24Let's think about this, because there's another point up for grabs

0:19:24 > 0:19:29for the team that can tell me which will cause more damage,

0:19:29 > 0:19:32jelly or corn starch mixed with water.

0:19:32 > 0:19:34Important to remember, in the case of the jelly,

0:19:34 > 0:19:39that water is locked up in it, but it can leave the jelly,

0:19:39 > 0:19:40and leave a pretty solid mass.

0:19:40 > 0:19:43But then the corn flour, when that's mixed with water,

0:19:43 > 0:19:45that is a non-Newtonian substance,

0:19:45 > 0:19:47so it can become solid when it's hit.

0:19:47 > 0:19:51There is a point up for grabs for whichever tells me.

0:19:51 > 0:19:53It's 1-all now, so this would be useful to win.

0:19:53 > 0:19:57Teams, what do we think?

0:19:57 > 0:19:59- Jelly. - You think the jelly.- Jelly.

0:19:59 > 0:20:02- Corn.- You're on the side of corn causing the most damage,

0:20:02 > 0:20:04you're on the side of jelly.

0:20:04 > 0:20:07OK. Let's have a look and carry on with the experiment.

0:20:12 > 0:20:15OK, so let's drop the bag of Jelly Woman's jelly

0:20:15 > 0:20:18and see what damage it does to the paving stones below.

0:20:18 > 0:20:20This time, for real. I promise.

0:20:20 > 0:20:22Five, four,

0:20:22 > 0:20:24three, two,

0:20:24 > 0:20:27one, drop.

0:20:30 > 0:20:33Well, not quite a direct hit, there,

0:20:33 > 0:20:36but enough that we can see the damage the jelly caused on impact.

0:20:36 > 0:20:40Remember, it's the damage to the paving stones we're looking at here.

0:20:40 > 0:20:44Corn Man can't believe it. Come on, that's not good sportsmanship.

0:20:47 > 0:20:50Right, let's get the corn starch up to 30 metres like before.

0:20:50 > 0:20:55We've made the contestants stand in the rain for long enough. Probably.

0:20:55 > 0:21:00So let's just get on with it. Three, two, one, drop.

0:21:01 > 0:21:03Again, not quite a direct hit,

0:21:03 > 0:21:08but we will definitely be able to see the damage clearly enough.

0:21:11 > 0:21:14Corn Man looks happy. Well, that's just weird.

0:21:14 > 0:21:17I'm not sure what all of that is about.

0:21:17 > 0:21:21You can see the corn starch has caused more damage to the stones.

0:21:21 > 0:21:25Jelly Woman, not impressed, and what's this? She's after revenge.

0:21:25 > 0:21:28Definitely not good sportsmanship.

0:21:29 > 0:21:32So, after thorough examination of the results,

0:21:32 > 0:21:34we can now announce that Corn Man

0:21:34 > 0:21:38is Britain's best ultimate new superhero talent person thing.

0:21:38 > 0:21:40He'll get a badge, he'll be happy.

0:21:40 > 0:21:44Looks like victory wasn't enough for Corn Man.

0:21:44 > 0:21:47He's got one last surprise for Jelly Woman.

0:21:47 > 0:21:50He's going to drop one giant bag of corn starch

0:21:50 > 0:21:53on her precious jellymobile.

0:21:53 > 0:21:54Oh no, her jelly!

0:21:54 > 0:21:56Oh, devastation, there,

0:21:56 > 0:22:00the bag crushing the back end of the car completely.

0:22:00 > 0:22:02Let's watch that in very slow motion.

0:22:06 > 0:22:08That brings the score to 2-1 to the Yellows.

0:22:08 > 0:22:11Anyway, it is time now for my favourite bit of the show.

0:22:11 > 0:22:15- Because it is.... - The Messy Messy Mess Test.

0:22:15 > 0:22:18Oh, yes, today, teams, you face the Bridge Of Destiny.

0:22:18 > 0:22:21The Bridge Of Destiny.

0:22:21 > 0:22:24I thought the Cobra Squad had taken care of you!

0:22:24 > 0:22:28Lab Rats, get him, get him, track him down. Here's how it works.

0:22:28 > 0:22:31Teams, you have to fish around in there to find parts of a bridge.

0:22:31 > 0:22:35Your prizes, such as a model speed boat, chemistry set and world orbs

0:22:35 > 0:22:38need to be transported across this revolting tank of rank.

0:22:38 > 0:22:42Construct your bridge out of the pieces in the fluids all around,

0:22:42 > 0:22:45and when you've finished, you pull this lever to release the car

0:22:45 > 0:22:49that pulls the trailer of prizes across the Bridge Of Destiny.

0:22:49 > 0:22:52The Bridge Of Destiny.

0:22:52 > 0:22:54Put him with the others.

0:22:54 > 0:22:57There are some squeegees in there too, to clean your bridge.

0:22:57 > 0:23:00It's up to you how much time you spend cleaning

0:23:00 > 0:23:01before you pull the lever.

0:23:01 > 0:23:04Yellows, you get a five second advantage.

0:23:04 > 0:23:06Reds, you go on the second klaxon and not before.

0:23:06 > 0:23:11The race to get your prize pods across the tank starts...now!

0:23:11 > 0:23:13KLAXON

0:23:13 > 0:23:15And there go the Yellows,

0:23:15 > 0:23:18moving as one being in their pursuit of greatness.

0:23:18 > 0:23:20There's the second siren

0:23:20 > 0:23:24and three waterproof clad present hungry bridge builders,

0:23:24 > 0:23:28the Red Team, burst into what could quite rightly be called action.

0:23:28 > 0:23:32And it looks as if the Reds might be first off the mark

0:23:32 > 0:23:36with a decisive piece of bridge section placement.

0:23:36 > 0:23:39The Yellows also look to be making their move,

0:23:39 > 0:23:42but the huge effort on both sides seems to be drawing a blank.

0:23:42 > 0:23:44It's too close to call at this stage.

0:23:44 > 0:23:47Fascinating experiment late last night,

0:23:47 > 0:23:49I managed to cross a lobster with a tiger.

0:23:49 > 0:23:52It's big, but I think I got it out.

0:23:52 > 0:23:54They'll find it. Probably.

0:23:54 > 0:23:57Or it might find them.

0:23:57 > 0:24:01Now whilst I was chatting, there, the whole landscape has changed,

0:24:01 > 0:24:04with both teams making huge progress.

0:24:04 > 0:24:07It's still neck and neck, though.

0:24:07 > 0:24:09I'm proud of this, it is proven to be

0:24:09 > 0:24:12able to start an argument amongst any group of people.

0:24:12 > 0:24:17We once got some monks that'd been living on a mountain for centuries,

0:24:17 > 0:24:20put them in there, within seconds, a big fight.

0:24:20 > 0:24:23This lot, though, are doing very well indeed.

0:24:23 > 0:24:28And the Reds have pulled the lever to release their payload of prizes.

0:24:28 > 0:24:30Looks like the Yellows have frozen in fear.

0:24:30 > 0:24:34The car is dragging the prizes ever nearer. Will it slip on the goo?

0:24:34 > 0:24:39- Yeah!- No, it's through. A glorious comeback win for the Reds.

0:24:39 > 0:24:42Wow!

0:24:42 > 0:24:45Woo-hoo! Well done.

0:24:45 > 0:24:49I mean, clearly, the result is the Reds win. Well done, Reds.

0:24:51 > 0:24:53But that was so hard, that.

0:24:53 > 0:24:57Well, Reds, let's find out what you've won, then. Your prize pods.

0:24:57 > 0:25:01Ninja Nan, are you ready? Each of you taking home battle spinners.

0:25:01 > 0:25:03World orbs.

0:25:03 > 0:25:06Butterfly garden. Nice!

0:25:06 > 0:25:09Model speedboat for each of you.

0:25:09 > 0:25:12A card set.

0:25:12 > 0:25:14Electronic game.

0:25:14 > 0:25:17And a chemistry set.

0:25:17 > 0:25:19A heart rate monitor for each of you.

0:25:19 > 0:25:23All of those prizes for the Reds, that's great.

0:25:23 > 0:25:26I mean, it must feel great right now, excited little faces, look.

0:25:26 > 0:25:28On the other side of the tank,

0:25:28 > 0:25:30slightly different set of circumstances,

0:25:30 > 0:25:33because you would have been taking those prizes with you,

0:25:33 > 0:25:36but you're not. Instead, on Blast Lab we have a fine, fine tradition

0:25:36 > 0:25:41that we must now uphold, because it's time for Bidet Goes Bang.

0:25:51 > 0:25:54Reds, well done, congratulations, you won through.

0:25:54 > 0:25:58All your prizes, coming home with you, which is a great feeling.

0:25:58 > 0:26:01On this side, Yellows, sorry.

0:26:01 > 0:26:06It was going so well, and then that last game is tough. Bad luck.

0:26:06 > 0:26:09But it's OK because as some sort of consolation,

0:26:09 > 0:26:11instead of taking them home with ya,

0:26:11 > 0:26:14you still get them, but then you blow them up.

0:26:14 > 0:26:16It's time for the walk of shame. Follow me.

0:26:16 > 0:26:18Aah!

0:26:18 > 0:26:24Yeah. It's heartbreaking. It's very sad.

0:26:30 > 0:26:35Oh, yeah. It's a moving scene all round.

0:26:37 > 0:26:41You've been a great team. Great sportsmanship, great skill.

0:26:41 > 0:26:46Great knowledge. And you still lost. You're going to blow your prizes up.

0:26:46 > 0:26:48Lift the handle, please. Lift the handle.

0:26:48 > 0:26:50Five,

0:26:50 > 0:26:51four,

0:26:51 > 0:26:53three, two,

0:26:53 > 0:26:54one.

0:26:59 > 0:27:01Thanks for coming in.

0:27:04 > 0:27:08Today we have learnt how air resistance can aid egg preservation

0:27:08 > 0:27:11and the impact jelly and corn flour can have on concrete slabs.

0:27:11 > 0:27:14That'd make a strange episode of Junior Masterchef!

0:27:14 > 0:27:16See you next time!

0:27:16 > 0:27:17Sorry, chaps.
