0:00:02 > 0:00:05What's the wobbliest form of transport?
0:00:05 > 0:00:07Oh, would it be one of those bendy buses?
0:00:07 > 0:00:09Cos all the time you're on them, they're always doing this.
0:00:09 > 0:00:11Or it could be, it could be on a bicycle,
0:00:11 > 0:00:13- cos they're quite difficult. - No, no, no.- Maybe...
0:00:13 > 0:00:16Or even a tricycle, I've never even ridden a tricycle.
0:00:16 > 0:00:17Or a unicycle, that'd be quite difficult.
0:00:17 > 0:00:19I've never ridden a unicycle.
0:00:19 > 0:00:21I'm going to give that a go, I'm going to see what that's like.
0:00:21 > 0:00:23It's a j... Oh.
0:00:29 > 0:00:33Can our teams help Guinea Pig speed his way along a slippery slide?
0:00:33 > 0:00:37Who will be speediest at splatting jelly?
0:00:38 > 0:00:40And will anyone hit this target?
0:00:43 > 0:00:48All that and more, it's time for Ultimate Brain!
0:00:48 > 0:00:51CHEERING
0:00:51 > 0:00:54Ha-ha-ha-ha! Good to see you again.
0:00:54 > 0:00:55Come on, boy, hup,
0:00:55 > 0:00:58there he is. My pet flea, Cornelius.
0:00:58 > 0:01:00I'm just training him, you see. Ha-ha-ha! Hey, guess what?
0:01:00 > 0:01:03If we practise a bit more, we could go on Britain's Got Talent.
0:01:03 > 0:01:05And then you could get to meet Simon Cowell!
0:01:05 > 0:01:07Where are you going?! I didn't mean it,
0:01:07 > 0:01:09you don't really have to meet Simon Cowell.
0:01:09 > 0:01:11Oh! I'd better go and get him.
0:01:11 > 0:01:13This is Ultimate Brain!
0:01:13 > 0:01:15Let's meet the teams.
0:01:15 > 0:01:18First, the team in green from delectable Doncaster,
0:01:18 > 0:01:21it's Evie, Tom and Dexter!
0:01:23 > 0:01:28Brilliant from Brighton, in yellow, it's Daniel, Ben and Sam!
0:01:28 > 0:01:32And our celebrity team in blue are The Three Ks from...
0:01:32 > 0:01:34HE HOWLS
0:01:34 > 0:01:35..Wolfblood.
0:01:35 > 0:01:39It's Shorelle, Rachel and Gabrielle.
0:01:39 > 0:01:41Once again, just for you,
0:01:41 > 0:01:46I have scoured the universe to find some of the brightest minds known to
0:01:46 > 0:01:48mankind. And I...
0:01:48 > 0:01:51HE GRUNTS
0:01:51 > 0:01:52HE HOWLS
0:01:52 > 0:01:54Oh, no, something strange is happening to me.
0:01:54 > 0:01:56HE HOWLS This can only mean one thing.
0:01:56 > 0:01:58Yes, it's time to meet our teams,
0:01:58 > 0:02:00beginning with the team from Wolfblood.
0:02:00 > 0:02:02They're the Blues!
0:02:02 > 0:02:05- How are you, Blues? - Good.- Good, thank you.
0:02:05 > 0:02:06Good to see you.
0:02:06 > 0:02:09Now, we've had a team on from your show before -
0:02:09 > 0:02:12Bobby, Louisa and Kedar.
0:02:12 > 0:02:14And guess what? They won!
0:02:14 > 0:02:17CHEERING AND APPLAUSE
0:02:17 > 0:02:19You've got a lot to live up to, haven't you?
0:02:19 > 0:02:20HE HOWLS
0:02:20 > 0:02:22- Uh-oh.- We do. - Let's see how well you do.
0:02:22 > 0:02:24What's your team name?
0:02:25 > 0:02:27The Three Ks. Thank you.
0:02:27 > 0:02:31- Moving on to the Yellows! How are you doing, Yellows?- Good.
0:02:31 > 0:02:34- Nice to see you. Where are you from? - Brighton.- Brighton.
0:02:34 > 0:02:36Brighton! By the sea. What's your team name?
0:02:39 > 0:02:41The Bubbly Brainiacs from Brighton.
0:02:41 > 0:02:45Who invent burglar alarms, is that right, Dr Ben?
0:02:45 > 0:02:47- Yes.- What's that all about, then?
0:02:47 > 0:02:49Basically, in year four,
0:02:49 > 0:02:53we made some burglar alarms and I thought I could test them out
0:02:53 > 0:02:56on my sister cos she kept on creeping into my room.
0:02:56 > 0:02:59- And what happened? - I caught her three times.
0:02:59 > 0:03:01DR BRAIN LAUGHS
0:03:01 > 0:03:03- Did you send her to prison? - No, I just told my mum.
0:03:03 > 0:03:07Ha-ha! I need one of those to stop Guinea Pig from stealing my bananas.
0:03:07 > 0:03:10DR BRAIN LAUGHS Here we go, it's the Greens.
0:03:10 > 0:03:12How are you, Greens?
0:03:12 > 0:03:14- Good.- Good, thanks. - Good to meet you.
0:03:14 > 0:03:17Dr Dexter, I hear you are a big fan...
0:03:17 > 0:03:20MIMICS BRIAN COX: ..of the wonders of the universe.
0:03:20 > 0:03:26And what can you tell me about your adventures in space and time?
0:03:26 > 0:03:30I know what the centre of a black hole is called,
0:03:30 > 0:03:32it's called the singularity.
0:03:32 > 0:03:36- Good one.- And I know the temperature of the core of the sun.
0:03:36 > 0:03:38Yes, 15 million degrees, isn't it?
0:03:38 > 0:03:39Yes.
0:03:39 > 0:03:43Oh! And I've heard you'd quite like to be an astronaut, is that right?
0:03:43 > 0:03:45- Or a scientist.- I think by the time you're old enough to actually be
0:03:45 > 0:03:47a professional astronaut,
0:03:47 > 0:03:50you might be in time to do the mission to Mars
0:03:50 > 0:03:51they keep talking about.
0:03:51 > 0:03:54Doop, doop, doop...
0:03:54 > 0:03:57- Dexter on Mars, that would be fantastic, wouldn't it?- Yes.
0:03:57 > 0:03:59Brilliant! What's your team name?
0:04:00 > 0:04:04Good luck on the show, and luck is what you're going to need because
0:04:04 > 0:04:06this is the show with a need for speed,
0:04:06 > 0:04:07a craving for creativity
0:04:07 > 0:04:10and a demand for ingenious ideas and inventions...
0:04:10 > 0:04:13and this is the warm-up!
0:04:15 > 0:04:18Not that type of warm-up, Guinea Pig.
0:04:18 > 0:04:19Give me my questions!
0:04:19 > 0:04:21BELL DINGS Good lad.
0:04:21 > 0:04:23Right, are you ready, teams?
0:04:23 > 0:04:25Hands on brains. Here we go.
0:04:25 > 0:04:33Take two, times it by four, then add seven, then divide by three.
0:04:33 > 0:04:35- HOWLS: Three Ks? - Five?
0:04:35 > 0:04:37- Is right!- Yay!
0:04:37 > 0:04:39What word am I spelling backwards?
0:04:44 > 0:04:46HOWLS: Three Ks?
0:04:46 > 0:04:47Circuit.
0:04:47 > 0:04:48Is correct.
0:04:48 > 0:04:50What is this sound?
0:04:50 > 0:04:52LOUD WIPING
0:04:57 > 0:04:59HOWLS: Three Ks.
0:04:59 > 0:05:00Windscreen wipers?
0:05:00 > 0:05:03- Is right!- Ooh!
0:05:03 > 0:05:06How many letters are there in the word "recycled"?
0:05:08 > 0:05:09Knowledgeable Newtons!
0:05:09 > 0:05:11Eight.
0:05:11 > 0:05:12Is correct!
0:05:12 > 0:05:16Now then, put yourselves in order of the length of your hair,
0:05:16 > 0:05:19the shortest this side and the longest that side.
0:05:19 > 0:05:21And when you've done it, press your brain.
0:05:21 > 0:05:23Bubbly Brainiacs.
0:05:23 > 0:05:24You've got to have a look.
0:05:24 > 0:05:26Yes, I'm going to give it to you.
0:05:26 > 0:05:27- Well done!- Yay!
0:05:27 > 0:05:29Wow! What a fantastic warm-up.
0:05:29 > 0:05:33And after that, The Three Ks are HOWLING ahead on six points.
0:05:33 > 0:05:36CHEERING AND APPLAUSE
0:05:39 > 0:05:42MIMICS THE COUNT: Welcome to my laboratory.
0:05:42 > 0:05:43Ah, ah, ah!
0:05:43 > 0:05:45So, what do you think I've got in front of me,
0:05:45 > 0:05:47- what do you think this looks like? - Newton balls.
0:05:47 > 0:05:50Oh, well, it's kind of like it, isn't it?
0:05:50 > 0:05:54- What do you think?- I have seen a Newton's cradle before and the balls
0:05:54 > 0:05:56are touching, but those aren't.
0:05:56 > 0:05:58They're not, are they? No, it is slightly different actually.
0:05:58 > 0:06:01Could be a sort of xylophone... # Brrring-ding-doon-doon. #
0:06:01 > 0:06:04Actually, no, it's just a pendulum arrangement that I've made.
0:06:04 > 0:06:08The difference between this and the Newton's cradle you talk about
0:06:08 > 0:06:11is that the strings on these are all different lengths.
0:06:11 > 0:06:15You see, as it goes along the line, they get longer and longer.
0:06:15 > 0:06:18What I'm going to ask you is,
0:06:18 > 0:06:19when I swing the ball one way
0:06:19 > 0:06:23at the exact same time and let them all go,
0:06:23 > 0:06:24what is going to happen?
0:06:24 > 0:06:26I'm going to give you some options.
0:06:26 > 0:06:29A, the balls will click together
0:06:29 > 0:06:31and form a sort of groovy drumbeat...
0:06:42 > 0:06:47Something that only you, or you, have thought of, and not even I.
0:06:47 > 0:06:48What could it be?
0:06:48 > 0:06:52Now then, you're thinking time starts now!
0:06:52 > 0:06:55- KLAXON BLARES - C.
0:06:55 > 0:06:58So, what will happen when I let go of the balls?
0:06:58 > 0:07:01Different lengths means different vibrations means...
0:07:02 > 0:07:04It will go like...
0:07:05 > 0:07:07The longer the chain...
0:07:07 > 0:07:09Have you got your answer?
0:07:09 > 0:07:12I think if it pulls back, each one will go one by one, by one, by one.
0:07:12 > 0:07:14Isn't that a snake?
0:07:14 > 0:07:16ALARM BLARES That's it, time's up!
0:07:16 > 0:07:19Let's see your answers...now!
0:07:19 > 0:07:21C, C, C.
0:07:21 > 0:07:23Everybody has gone for C.
0:07:23 > 0:07:25Let's start with the Greens.
0:07:25 > 0:07:26Why have you gone for C, Greens?
0:07:26 > 0:07:29Partly because I've seen a giant one in action.
0:07:29 > 0:07:31- So you're using your memory?- Yeah.
0:07:31 > 0:07:33- Yellows.- We think it will snake
0:07:33 > 0:07:35because longer strings will take longer,
0:07:35 > 0:07:37so it will look like a snake.
0:07:37 > 0:07:39Ah, I see!
0:07:39 > 0:07:42Now then, Blues, you've also gone for C.
0:07:42 > 0:07:44What's your scientific thinking?
0:07:44 > 0:07:46Well, I think we agree with Dr Ben,
0:07:46 > 0:07:48in terms of the different lengths of the string,
0:07:48 > 0:07:51so that'll make a snake affect.
0:07:51 > 0:07:53Everybody's gone for C. Well, shall we see?
0:07:53 > 0:07:55Right, come on, then, let's do it.
0:07:55 > 0:07:57Here we go.
0:07:57 > 0:08:00I'm going to just gently pull them all out this way,
0:08:00 > 0:08:03like this, at the same time, so they are the same distance.
0:08:03 > 0:08:07And then, I'm going to let go!
0:08:07 > 0:08:08Let's see what happens.
0:08:08 > 0:08:11Ah, yes, look!
0:08:11 > 0:08:13- ALL:- Yeah! - Watch what happens now.
0:08:13 > 0:08:16It's starting to wiggle, getting even more snaky,
0:08:16 > 0:08:19getting even curlier, isn't it?
0:08:19 > 0:08:21There we go, there's our snake.
0:08:21 > 0:08:24Whoo! Isn't it fantastic?
0:08:24 > 0:08:26- Yeah.- Beautiful, isn't it?
0:08:26 > 0:08:27Ha-ha-ha!
0:08:27 > 0:08:30This pendulum swing has been specially designed
0:08:30 > 0:08:31to create this mesmerising pattern,
0:08:31 > 0:08:34and the key is in the difference in the length of the chains
0:08:34 > 0:08:36on which the bob weights hang.
0:08:36 > 0:08:38In equilibrium, the forces acting on them are perfectly balanced,
0:08:38 > 0:08:40and the strings hang vertically.
0:08:40 > 0:08:42But bring in gravity
0:08:42 > 0:08:44by lifting and dropping them all from a level height
0:08:44 > 0:08:47and that's when the difference in their period of oscillation
0:08:47 > 0:08:48comes into play.
0:08:48 > 0:08:49The longer the string,
0:08:49 > 0:08:52the greater the amount of time it will take to complete one swing of
0:08:52 > 0:08:55the circular arc. By careful calculation of each chain's length,
0:08:55 > 0:08:58we get this wonderfully wavy effect.
0:08:58 > 0:09:00Science in action. Even though they're acting independently,
0:09:00 > 0:09:05when viewed together, it looks like they're dancing in motion together.
0:09:05 > 0:09:07Ha-ha-ha! The choreography of science.
0:09:07 > 0:09:11The first person who really discovered this was Galileo, of...
0:09:11 > 0:09:15# Galileo, Galileo, Galileo, Figaro Magnifico... # ..fame.
0:09:15 > 0:09:18And he used this to invent the first pendulum clock!
0:09:18 > 0:09:19All of you were right.
0:09:19 > 0:09:22- Yes!- You all get ten points!
0:09:22 > 0:09:25Well done, teams. Marvellous. ALL CHEER
0:09:25 > 0:09:28They've certainly got into the swing of things.
0:09:28 > 0:09:29SWING OF THINGS! Points all round.
0:09:29 > 0:09:32CHEERING AND APPLAUSE
0:09:33 > 0:09:35I've been a bit fed up lately
0:09:35 > 0:09:39because I get very tired walking around my laboratory all day.
0:09:39 > 0:09:41I get really, really achy feet.
0:09:41 > 0:09:43And that last challenge gave me an idea.
0:09:43 > 0:09:45How do snakes get around?
0:09:45 > 0:09:48Oh, yes, they slip and slide, don't they?
0:09:48 > 0:09:49That sounds much easier,
0:09:49 > 0:09:52so I've asked my teams to devise ways to make
0:09:52 > 0:09:55humans slip really, really fast.
0:09:55 > 0:09:59And I gave them a budget of £50 and two days
0:09:59 > 0:10:00to come up with their plans.
0:10:00 > 0:10:04Teams must think of a way to help GP launch himself onto and travel along
0:10:04 > 0:10:06the polythene pathway,
0:10:06 > 0:10:09thinking about how to make GP as slippery as possible
0:10:09 > 0:10:11as he travels down the slope.
0:10:11 > 0:10:13The team whose plan helps GP reach the greatest distance
0:10:13 > 0:10:18in the time allowed will win a whopping ten Honour Points!
0:10:18 > 0:10:24And who better to test them than my very own Mr Guinea Pig?!
0:10:24 > 0:10:27CHEERING Ha-ha-ha!
0:10:27 > 0:10:32Uh... My very own Mr Guinea Pig!
0:10:32 > 0:10:36It's all right, Guinea Pig, come on. LAUGHTER
0:10:37 > 0:10:39- What's the matter? - I'm not coming out.
0:10:39 > 0:10:41- Why?- Because I heard there's a slippery,
0:10:41 > 0:10:43slidey snake somewhere in the studio.
0:10:43 > 0:10:47No, it wasn't a real one, it was a pendulum-y thing.
0:10:47 > 0:10:49It's you who's going to be slipping and sliding.
0:10:49 > 0:10:50- Oh.- Yeah.
0:10:50 > 0:10:53DR BRAIN LAUGHS Come on then, GP!
0:10:53 > 0:10:55- That's OK, then.- You feel a bit better now?- Yeah.- Good.
0:10:55 > 0:10:57Because we are going to make you fall over again.
0:10:57 > 0:11:00LAUGHTER Let's see the first plan.
0:11:00 > 0:11:05Um, Yellows, are you big fans of Pingu or something?
0:11:05 > 0:11:08- Yeah.- What's going on?!
0:11:08 > 0:11:10What have you got him dressed up like that for?
0:11:10 > 0:11:12We thought about penguins.
0:11:12 > 0:11:15In the wild, they slide on their bellies to get into the water.
0:11:15 > 0:11:18Oh, they do, don't they? You see them going schaaawwwn!
0:11:18 > 0:11:23And we've put the hat and the flippers to increase aerodynamics,
0:11:23 > 0:11:25so he has to put his head up.
0:11:25 > 0:11:28The egg's going to go in-between his legs to increase momentum.
0:11:28 > 0:11:30To increase momentum.
0:11:30 > 0:11:33- So it's got some weight behind it? - Yes.- Oh, I see,
0:11:33 > 0:11:34and you're hoping that extra weight
0:11:34 > 0:11:36is going to push him a bit quicker down the slide?
0:11:36 > 0:11:39- Yes.- The olive oil and the washing-up liquid
0:11:39 > 0:11:41is to lubricate the slide.
0:11:41 > 0:11:43He's going to mix it together and then put it on his belly,
0:11:43 > 0:11:45so then hopefully he will slide further.
0:11:45 > 0:11:48And what's that white thing actually made of?
0:11:48 > 0:11:51- We were thinking of a slippy material...- Yes.
0:11:51 > 0:11:53..which will also protect him
0:11:53 > 0:11:55when he's sliding down so he doesn't get burnt.
0:11:55 > 0:11:57Oh, that's so considerate.
0:11:57 > 0:12:00You see, they're thinking about you, Guinea Pig.
0:12:00 > 0:12:02They care about you, isn't that lovely?
0:12:02 > 0:12:05Ah! They're still going to throw you down a slide, though.
0:12:05 > 0:12:08So, I don't think they care about you that much, do they?
0:12:08 > 0:12:12The Bubbly Brainiacs have given GP a smooth front to minimise friction
0:12:12 > 0:12:15as he comes into contact with the slope.
0:12:15 > 0:12:19Plus, they're going all-out using both oil AND washing-up liquid
0:12:19 > 0:12:20as lubricants.
0:12:20 > 0:12:24They're hoping an egg-shaped weight between GP's legs will aid
0:12:24 > 0:12:27his battle against any air resistance, add balance and increase
0:12:27 > 0:12:30momentum, putting faith in their lubrication
0:12:30 > 0:12:34to counteract any increased drag through friction.
0:12:34 > 0:12:36OK, Guinea Pig, get lubricating!
0:12:36 > 0:12:38KLAXON BLARES
0:12:38 > 0:12:40- Olive oil.- Open the oil.
0:12:40 > 0:12:43Over your belly. Over your belly...
0:12:43 > 0:12:45It is quite a slippery substance, olive oil.
0:12:45 > 0:12:47And now the washing-up liquid.
0:12:47 > 0:12:49Open up the washing-up liquid.
0:12:49 > 0:12:51And then squirt that all over your belly.
0:12:51 > 0:12:53And then put some of it on the slide.
0:12:53 > 0:12:55Three, two, one! ALARM BLARES
0:12:55 > 0:12:57You've got to go, Guinea Pig!
0:12:57 > 0:12:59You've got to go! He's picking up the rugby egg.
0:12:59 > 0:13:01Come on, then, GP.
0:13:01 > 0:13:02Off you go.
0:13:02 > 0:13:04Splat.
0:13:04 > 0:13:07He's trying to move, he's having a wriggle.
0:13:07 > 0:13:10- Put your legs down and flap. - Legs down and flap.
0:13:10 > 0:13:13He's pretty much reached about as far as he's going to go, isn't he?
0:13:13 > 0:13:16- He's going.- He's still having a flap.- Keep going!
0:13:16 > 0:13:18You can tell him.
0:13:18 > 0:13:20Keep going! Keep going!
0:13:20 > 0:13:22Oh, that's a good movement.
0:13:22 > 0:13:24But he is getting somewhere.
0:13:24 > 0:13:26He's moving... ALARM BLARES
0:13:26 > 0:13:28- Time up.- Yeah!
0:13:28 > 0:13:31Hmm. An interesting pairing of lubricants here.
0:13:31 > 0:13:35As a detergent, washing-up liquid actually breaks down oil,
0:13:35 > 0:13:37with the hydrophobic ends of its hydrocarbon chains
0:13:37 > 0:13:39grabbing onto the oil molecules.
0:13:39 > 0:13:41That made no odds here, though.
0:13:41 > 0:13:44By using such volume of these two super-slippy liquids,
0:13:44 > 0:13:46we saw some effective slippage.
0:13:46 > 0:13:51HOWLS: It's the Blues. Shorelle, Rachel, Gabrielle.
0:13:51 > 0:13:53Otherwise known as...Triple K!
0:13:53 > 0:13:56So, Blues, what's the name of your plan?
0:13:56 > 0:13:58- ALL:- The K Ship. - Ooh!
0:13:58 > 0:14:03And the idea is that it's an inflatable rubber spaceship,
0:14:03 > 0:14:05so because it's quite light,
0:14:05 > 0:14:08it should go far, and because of the foil,
0:14:08 > 0:14:11it should glide on top of the slip and slide.
0:14:11 > 0:14:13And then we wanted to lubricate it
0:14:13 > 0:14:16with some olive oil on the underside.
0:14:16 > 0:14:18So it's not a giant bagel, then?
0:14:18 > 0:14:20- GIRLS LAUGH - Sorry!
0:14:20 > 0:14:22That's a shame. Guinea Pig, how do you feel?
0:14:22 > 0:14:25I feel I should change my name to ET-GP.
0:14:25 > 0:14:27LAUGHTER
0:14:27 > 0:14:30The Three Ks are hoping to launch GP to victory,
0:14:30 > 0:14:33adding tinfoil to a rubber wing.
0:14:33 > 0:14:36Combined with the spread of his weight across a larger surface area,
0:14:36 > 0:14:38they're hoping this coating
0:14:38 > 0:14:40will make for a smoother run, reducing friction.
0:14:40 > 0:14:43Their lubricant of choice is olive oil -
0:14:43 > 0:14:45for space-age slippery, sliding superpowers.
0:14:45 > 0:14:47And similar to the Yellows,
0:14:47 > 0:14:51they've added heavy bags of rice that they hope will aid momentum.
0:14:51 > 0:14:53Is GP about to rock it down the slope?
0:14:53 > 0:14:56Prepare for blastoff!
0:14:56 > 0:14:58Let's start your time...now!
0:14:58 > 0:15:00- KLAXON BLARES - Oil.- Open the olive oil.
0:15:00 > 0:15:02Spread it all over the bottom.
0:15:02 > 0:15:04Probably put it on your hand.
0:15:04 > 0:15:06- Yeah, OK.- Around the ring. - Yes. That's it.
0:15:06 > 0:15:09- ALL:- Spread it around with your hands.
0:15:09 > 0:15:12And on the next noise, you've got to go, so waiting...
0:15:12 > 0:15:15Turn it over. And you're going to go forwards.
0:15:15 > 0:15:18He needs to sit in it backwards and push himself with his feet.
0:15:18 > 0:15:20- OK, yes... - ALARM BLARES
0:15:20 > 0:15:22- You've got to go! - Backwards. That way.
0:15:22 > 0:15:24- Go, go, go! - Push back with your feet.
0:15:24 > 0:15:26What's he got on his feet?
0:15:26 > 0:15:29- He's got rice bags. - LAUGHTER
0:15:29 > 0:15:31It is a bit of a struggle.
0:15:32 > 0:15:36Oh, now he's started to move a little bit.
0:15:36 > 0:15:38With that little motion he's doing.
0:15:38 > 0:15:40He's moving a bit more.
0:15:40 > 0:15:43- That was a bad idea.- Yes!
0:15:43 > 0:15:45How else are we...?
0:15:45 > 0:15:47We think maybe... ALARM BLARES
0:15:47 > 0:15:50- Time's up, I'm afraid. Your time is up.- Oh!
0:15:50 > 0:15:53Did those heavy bags of rice work in opposition to their attempts
0:15:53 > 0:15:56to spread out GP's weight across that giant ring?
0:15:56 > 0:15:59He certainly wasn't going anywhere fast, was he?
0:15:59 > 0:16:01So let's have a look at the Green plan.
0:16:01 > 0:16:03Let's hope it's not at all scary.
0:16:03 > 0:16:05MUSIC: Jaws Theme Aah! Ooh!
0:16:05 > 0:16:09Shark, shark! Ooh... Oh... Oh, it's you, Guinea Pig!
0:16:09 > 0:16:13So, Greens, talk me through this plan.
0:16:13 > 0:16:14What's going on?
0:16:14 > 0:16:17Well, we decided to put Guinea Pig in a streamline
0:16:17 > 0:16:19because if you look at bobsleighs,
0:16:19 > 0:16:21they're all in a line, it's easier for them to go down.
0:16:21 > 0:16:26We have used the bin bag because it's sort of super-slippy.
0:16:26 > 0:16:27Oh, I see.
0:16:27 > 0:16:30And we've decided to put washing-up liquid all over him,
0:16:30 > 0:16:31all over his front.
0:16:31 > 0:16:33Ah, yes, that'll make it really slippy.
0:16:33 > 0:16:37We used the tape to hold the cotton and the tape together.
0:16:37 > 0:16:40Oh, I see, that'll keep it nice and solid, won't it?
0:16:40 > 0:16:42Nice and sturdy. Good thinking.
0:16:42 > 0:16:43How do you feel, GP?
0:16:43 > 0:16:45I feel like I should be called...
0:16:47 > 0:16:49Which is the Latin name for a great white shark.
0:16:49 > 0:16:52Ooh! Get him! LAUGHTER
0:16:54 > 0:16:56Like the Yellows, Knowledgeable Newtons
0:16:56 > 0:16:58have been inspired by nature,
0:16:58 > 0:17:01turning GP into a super-streamlined slippery shark.
0:17:01 > 0:17:03Keeping the design as compact as possible,
0:17:03 > 0:17:05they hope to reduce air resistance,
0:17:05 > 0:17:07and with a smooth plastic covering to his body,
0:17:07 > 0:17:10minimise friction on our slippery slope,
0:17:10 > 0:17:12helped further by washing-up liquid.
0:17:12 > 0:17:14As with other plans, aiding lubrication.
0:17:14 > 0:17:17Will this shark attack kill all hope for the opposition?
0:17:17 > 0:17:20Or at least scare them off? Let's find out.
0:17:21 > 0:17:23Shark attack.
0:17:23 > 0:17:26HUMS JAWS THEME
0:17:26 > 0:17:28Let's see it in action, then.
0:17:28 > 0:17:30Three, two, one - get lubricating!
0:17:30 > 0:17:32- KLAXON BLARES - Put it all over.
0:17:32 > 0:17:35All over, Guinea Pig, literally.
0:17:35 > 0:17:38Absolutely everywhere! On your legs.
0:17:38 > 0:17:40- Legs!- Everywhere.
0:17:40 > 0:17:41- Put loads on.- Everywhere!
0:17:41 > 0:17:44- You tell him.- Arms.- Arms, arms, arms. Legs, legs, legs.
0:17:44 > 0:17:46Do it a bit more on your legs.
0:17:46 > 0:17:49- Put it everywhere!- Yes, yes, yes!
0:17:49 > 0:17:51Loads and loads and loads.
0:17:51 > 0:17:54He looks nice and slippy now. ALARM BLARES
0:17:54 > 0:17:56That's it, off you go, Guinea Pig!
0:17:56 > 0:17:58- Let's see how he does.- Go!
0:17:58 > 0:18:00Oh, look at that!
0:18:00 > 0:18:03- Go, go, go!- Go on, Guinea Pig.
0:18:03 > 0:18:05Like a shark.
0:18:05 > 0:18:08- Go on, Guinea Pig!- What do you think he should do now?
0:18:08 > 0:18:09- Guinea Pig!- See how far he can get.
0:18:09 > 0:18:12Oh, he's come to a bit of a standstill.
0:18:12 > 0:18:13Need him to go quicker.
0:18:13 > 0:18:15- LAUGHTER Slipping away.- Come on!
0:18:15 > 0:18:18- Like a shark out of water. - Come on, Guinea Pig!
0:18:18 > 0:18:20LAUGHTER Oh, he's gone on his side!
0:18:20 > 0:18:23- Go, go, go!- Go on, Guinea Pig!
0:18:23 > 0:18:25ALARM BLARES That's your time up!
0:18:25 > 0:18:28What a combo of material and lubricant!
0:18:28 > 0:18:31With weak forces between the molecules of the fluid
0:18:31 > 0:18:32compared to the solid surface,
0:18:32 > 0:18:35moving easily between the plastic above and below.
0:18:35 > 0:18:37And I can tell you the first result
0:18:37 > 0:18:41is that Guinea Pig is absolutely exhausted, look at him.
0:18:41 > 0:18:44Poor thing! Ha-ha-ha! You've wiped him out!
0:18:44 > 0:18:47Ha-ha-ha! And now I can tell you the second result
0:18:47 > 0:18:50is that the team that came in last place...
0:18:52 > 0:18:53..was...
0:18:54 > 0:18:57HE HOWLS
0:18:59 > 0:19:02Perhaps going backwards wasn't such a great plan after all.
0:19:02 > 0:19:04Unlucky, unlucky.
0:19:04 > 0:19:06I can say, in second place,
0:19:06 > 0:19:10meaning they get five points, is the Yellows!
0:19:10 > 0:19:13LAUGHTER
0:19:14 > 0:19:18I'm awarding five points there because you mirrored nature and
0:19:18 > 0:19:22applied that in your science, and I like that kind of thinking.
0:19:22 > 0:19:24We reward good thinking on Ultimate Brain.
0:19:24 > 0:19:27But that means, of course, you, Greens, get ten points!
0:19:27 > 0:19:29- Well done.- Yay!
0:19:30 > 0:19:32A great victory there for the Greens.
0:19:32 > 0:19:35Now let's see how they get on in the next round.
0:19:35 > 0:19:38CHEERING AND APPLAUSE
0:19:42 > 0:19:46Ha-ha! Me and Guinea Pig love a good party, don't we?
0:19:46 > 0:19:48Oh, the music, dancing.
0:19:48 > 0:19:51Ice cream. And jelly.
0:19:51 > 0:19:54Jelly. We hate jelly, don't we?
0:19:54 > 0:19:58We hate it! Jelly must be destroyed!
0:19:58 > 0:20:00It is what this challenge is all about.
0:20:00 > 0:20:03Yes, our three contestants have their jelly in front of them,
0:20:03 > 0:20:07and all we're going to do is, on the sound of the Guinea Pig squeal,
0:20:07 > 0:20:10they're going to whack their jelly as fast as they can,
0:20:10 > 0:20:13and the one who hits their jelly the fastest wins!
0:20:13 > 0:20:14Are you ready, teams?
0:20:14 > 0:20:16- ALL:- Yes!
0:20:20 > 0:20:22Oh, mercy!
0:20:22 > 0:20:26But who was the quickest? Let's have a look at the replay.
0:20:26 > 0:20:27Wobbly wowzers!
0:20:27 > 0:20:30But whose jiggly jelly was the quickest to quake?
0:20:30 > 0:20:32I can't quite tell with the naked eye.
0:20:32 > 0:20:37Let's check the slow-motion camera.
0:20:39 > 0:20:41Well, that jelly suddenly has all been destroyed,
0:20:41 > 0:20:43but one team got smashing first.
0:20:43 > 0:20:46Well, we can see it was a victory for the Yellows!
0:20:46 > 0:20:48Ten points!
0:20:48 > 0:20:50# Jelly on a plate Jelly on a plate
0:20:50 > 0:20:53# Wibble wobble, wibble wobble Jelly on a plate. #
0:20:53 > 0:20:54Ha-ha! # Jelly on a plate. #
0:20:54 > 0:20:56I'm just going to keep singing and dancing
0:20:56 > 0:20:59right through to the next round!
0:21:05 > 0:21:09Guinea-ma-Pig, what do you know about bouncing?
0:21:09 > 0:21:11- Bouncing?- Yeah.- I can bounce.
0:21:11 > 0:21:14# Bounce, baby, bounce... #
0:21:14 > 0:21:17Well, that's good, because this challenge is all about bouncing.
0:21:17 > 0:21:21Now, our contestants have got a selection of balls here.
0:21:21 > 0:21:22You've got a basketball here.
0:21:22 > 0:21:23Do-o-o-o-ing!
0:21:23 > 0:21:25Got a tennis ball here.
0:21:25 > 0:21:29Sho-o-o-o-ing! And here is a little ball of Blu-tack.
0:21:29 > 0:21:34Splat! So, what they've got to do is they've got to try and bounce one or
0:21:34 > 0:21:38a combination of any of these balls, bounce them,
0:21:38 > 0:21:40and try and hit the target.
0:21:40 > 0:21:43But they can only drop the balls, they can't throw them.
0:21:43 > 0:21:46Ah! Do you think you could hit the target?
0:21:46 > 0:21:48Yeah, I reckon I could do it, Dr Brain.
0:21:48 > 0:21:49Go on, then! Give it a go!
0:21:51 > 0:21:54I... I meant with one of the balls.
0:21:54 > 0:21:59Oh, Guinea Pig. Let's hope our teams are more inspired.
0:21:59 > 0:22:01Your time starts...now! KLAXON BLARES
0:22:01 > 0:22:03I'm thinking, if we drop the basketball
0:22:03 > 0:22:05and then drop the tennis ball on top of the basketball,
0:22:05 > 0:22:07and then the Blu-tack on top of the tennis ball.
0:22:07 > 0:22:10They should bounce off each other and hit the target.
0:22:10 > 0:22:11Straight to it, Dr Shorelle.
0:22:11 > 0:22:14- OK, do it.- OK.
0:22:15 > 0:22:18Off to a flying start! LAUGHTER
0:22:18 > 0:22:21Right, everyone get one. You go first, Dexter.
0:22:21 > 0:22:23- OK.- OK, that's reasonably good.
0:22:23 > 0:22:25Tom, drop it.
0:22:25 > 0:22:27That was really bad.
0:22:27 > 0:22:29Fire!
0:22:29 > 0:22:33We've got to, like... It's shooting that way, so we...
0:22:33 > 0:22:36- That ain't going to work. - Yeah, try it that way.
0:22:36 > 0:22:38Now it's shooting that way!
0:22:38 > 0:22:41So we all have to drop it at the same time and hope for the best.
0:22:41 > 0:22:42OK.
0:22:43 > 0:22:45- OK. OK.- That didn't work.
0:22:45 > 0:22:46No, let's try again.
0:22:46 > 0:22:48That one, when it hits the floor,
0:22:48 > 0:22:53drop another one so that it'll hit that and hopefully reach the target.
0:22:53 > 0:22:56- OK, we need to...- Oh, looks like you're onto something, Greens.
0:22:56 > 0:23:00- Or not.- Keep trying that idea, hopefully...
0:23:00 > 0:23:03- Whoa, Yellows! - You drop when that gets back up.
0:23:03 > 0:23:05- OK.- OK.- Ready?
0:23:05 > 0:23:08- Yeah.- Go. - This technique is catching on.
0:23:08 > 0:23:10You make sure it's in line.
0:23:10 > 0:23:12Three, two, one, go.
0:23:12 > 0:23:15- It's not in line.- Ooh! - Dr Dexter is not the target!
0:23:15 > 0:23:18- Wow.- So close, Yellows!
0:23:18 > 0:23:19Do it again, Ben.
0:23:22 > 0:23:23- That way...- Tom!
0:23:23 > 0:23:27- This way...- Tom! - LAUGHTER
0:23:27 > 0:23:29Any way but up.
0:23:29 > 0:23:30Come on!
0:23:31 > 0:23:34Ooh, Greens! That was nearly it, that was nearly it!
0:23:34 > 0:23:36They've definitely made a discovery here.
0:23:36 > 0:23:38- Go on.- Got it?- Go on, then.- No.
0:23:40 > 0:23:41Oh!
0:23:41 > 0:23:42Go.
0:23:42 > 0:23:44Yes! ALARM BLARES
0:23:46 > 0:23:47- ALL:- Oh!
0:23:47 > 0:23:49You did it!
0:23:49 > 0:23:50Well done!
0:23:50 > 0:23:54So, that was a pretty interesting one, wasn't it?
0:23:54 > 0:23:57- Yeah.- Most of you got the principle pretty quickly, didn't you?
0:24:01 > 0:24:06But only one team actually managed to hit the target.
0:24:07 > 0:24:08Go.
0:24:08 > 0:24:10GASPING
0:24:10 > 0:24:11Yes!
0:24:11 > 0:24:14And that was...the Greens!
0:24:14 > 0:24:18Well done, you three. You get ten points.
0:24:18 > 0:24:22But because the rest of you got the principle and you nearly,
0:24:22 > 0:24:24nearly got it, I'm going to give you two points each.
0:24:24 > 0:24:25So, well done to you.
0:24:25 > 0:24:28CHEERING AND APPLAUSE
0:24:28 > 0:24:31- What do you think this was for? - Sticking it to the target?
0:24:31 > 0:24:34Almost. What you could have done - take a little piece of this...
0:24:34 > 0:24:37HE HUMS
0:24:37 > 0:24:41Stick the tennis ball onto here, and hopefully what would happen is,
0:24:41 > 0:24:43as you take it over,
0:24:43 > 0:24:46very elegantly just drop, thuswise...
0:24:46 > 0:24:47And there you go.
0:24:47 > 0:24:49- ALL:- Oh! - ALARM BLARES
0:24:49 > 0:24:52The heavier basketball transfers its energy to the lighter tennis ball,
0:24:52 > 0:24:54and fixing it in place helps with aim.
0:24:54 > 0:24:56Score!
0:24:56 > 0:24:59That's how it's done. There you go.
0:24:59 > 0:25:02Now it's time for the quickfire round!
0:25:02 > 0:25:05Quick, quick, we've got to go!
