0:00:06 > 0:00:09What happens when you wash up a plate covered in milk?
0:00:09 > 0:00:11Can Guinea Pig save this cat from a fate worse than
0:00:11 > 0:00:13falling off a seesaw?

0:01:34 > 0:01:36Dr Seren, what would you like to be
0:01:36 > 0:01:39when all that school stuff's behind you, that time they call growing up?
0:01:39 > 0:01:41What do you think? What would you like to do?
0:01:41 > 0:01:43I would like to be a doctor.
0:01:43 > 0:01:46A doctor! Now, why particularly a doctor?
0:01:46 > 0:01:48Because I would like to help people when they're ill.
0:01:48 > 0:01:50HE SOBS
0:01:50 > 0:01:52That's so lovely! Let's sing a song about it.

0:02:33 > 0:02:35Now, then.
0:02:35 > 0:02:38Dr Jordan, I hear that you're a bit of a language expert.
0:02:38 > 0:02:40- Yes.- Is this correct?
0:02:40 > 0:02:43I can speak English, French, and Spanish.
0:02:43 > 0:02:47That's marvellous. And can you speak, er...
0:02:47 > 0:02:48Fran-ish,
0:02:48 > 0:02:51which is a mixture between French and Spanish?
0:02:51 > 0:02:52Yes, I can.
0:02:52 > 0:02:53Go ahead. Let's hear it.

0:03:08 > 0:03:09Yes?
0:03:09 > 0:03:13I hear that you are a dancer of extreme wonderfulness. Is this true?
0:03:13 > 0:03:15It is true.
0:03:15 > 0:03:19Very, very good. Now, would you mind doing a few little moves for us?
0:03:19 > 0:03:20Could do a bit of tap?
0:03:20 > 0:03:22Yeah, that'd be nice.
0:03:22 > 0:03:27TAP MUSIC PLAYS
0:03:27 > 0:03:31Oh, look! That is marvellous! I can do the splits.
0:03:31 > 0:03:34Banana splits. Ho-ho-ho! Marvellous.
0:03:34 > 0:03:35What's your team name today?
0:03:35 > 0:03:37ALL: We are the Dixi-Chicks!
0:03:37 > 0:03:39- CHEERING - The Dixi-Chicks! I love it.
0:03:39 > 0:03:40That's the teams. Remember!
0:03:40 > 0:03:43To win points on this show with the hope of walking away with
0:03:43 > 0:03:46honour most audacious, you are here to demonstrate extreme
0:03:46 > 0:03:49levels of genius in the face of thrilling awesomeness!
0:03:49 > 0:03:51Can you handle that?
0:03:51 > 0:03:52ALL: Yeah!
0:03:52 > 0:03:54I knew you could!
0:03:54 > 0:03:57Let's have the first round.
0:03:57 > 0:03:59Psh-stoink!
0:04:03 > 0:04:04CHEERING
0:04:04 > 0:04:08Now... This brain ignition challenge is all about marvellous,
0:04:08 > 0:04:09marvellous, lovely milk.
0:04:09 > 0:04:14I do like a nice glass of this ice cold stuff, don't you? Ha-ha-hm-hm!
0:04:14 > 0:04:18Mm. Oh, it's so cold. Brr!
0:04:19 > 0:04:23Sorry! Had a bit of a brain freeze then. Ha-ha-ha-ha! Where was I?
0:04:23 > 0:04:27Oh, yes! What we have here is a pool of milk, you see.
0:04:27 > 0:04:31Now, what I'm going to do is I'm going to add some inks
0:04:31 > 0:04:33here of different colours into the milk.
0:04:33 > 0:04:36Little splosh of red, which in French is, of course...
0:04:36 > 0:04:37Rouge.
0:04:37 > 0:04:39Rouge. Merci.
0:04:39 > 0:04:40There, you see.
0:04:40 > 0:04:43I like this, having a bit of language in with the science today.
0:04:43 > 0:04:47And, of course, as well as science and language, we are now making art.
0:04:47 > 0:04:50It's a wonderful rainbow of milky goodness.
0:04:50 > 0:04:51Now, my brain boffins!
0:04:51 > 0:04:55The question is - what do you think will happen when I add
0:04:55 > 0:05:01some of this wonderful stuff here, washing up liquid, into the milk?
0:05:01 > 0:05:03Ah!
0:05:03 > 0:05:05This could be about reactions, chemistry
0:05:05 > 0:05:07and all that kind of stuff. Look at the confusion on their faces!
0:05:07 > 0:05:09Now the answer is actually quite easy,
0:05:09 > 0:05:14but to make it even simpler, we're going to give you four choices.
0:05:14 > 0:05:15Will the washing up liquid...
0:05:27 > 0:05:29Blb-blb-blb. A bit like I do in the bath
0:05:29 > 0:05:32when Mummy Brain makes one of her lovely banana curries.
0:05:32 > 0:05:36Or will be something else entirely different that perhaps
0:05:36 > 0:05:39I haven't thought of... Me? Dr Brain?
0:05:39 > 0:05:43Something that I haven't thought of? Is that possible, do we think?
0:05:43 > 0:05:46Well, it might be, mightn't it? Ha-ha!
0:05:46 > 0:05:49So mash your mighty minds together and decide amongst yourselves.
0:05:49 > 0:05:51Your conferring time starts...
0:05:51 > 0:05:52now!
0:05:54 > 0:05:56So just four choices here.
0:05:56 > 0:05:58It should be pretty easy, don't you think?
0:05:58 > 0:06:01Now the teams need to think carefully about
0:06:01 > 0:06:02what will happen to the milk.
0:06:02 > 0:06:04Have you thought of your answer?
0:06:06 > 0:06:09Introducing new Dairy Washing Up Liquid.
0:06:09 > 0:06:13It cleans your dishes while making them all milky at the same time.
0:06:13 > 0:06:16# Primate paws that clean dishes
0:06:16 > 0:06:18# Feel soft and stink of milk
0:06:18 > 0:06:22# Yes it's mild multicoloured Dairy Liquid. #
0:06:22 > 0:06:24BUBBLING
0:06:24 > 0:06:27Teams! Thinking time is over. Have you thunk hard enough?
0:06:27 > 0:06:28ALL: Yes.
0:06:28 > 0:06:30You're pretty confident with the answers?
0:06:30 > 0:06:31ALL: Yes.
0:06:31 > 0:06:36I like that. Now, reveal your answers now!
0:06:36 > 0:06:37Let's see what we've got.
0:06:37 > 0:06:39B, a C, and a B.
0:06:39 > 0:06:43Oh, BBC! CBBC. Brilliant! He-he-he!
0:06:43 > 0:06:45Bit of free advertising there. Lovely. Thanks, guys.
0:06:45 > 0:06:50So, marvellous. I think we're going to start with the Greens! Now, then.
0:06:50 > 0:06:53You've gone for C. Now, what's your thinking behind that?
0:06:53 > 0:06:58When you use washing up liquid to wash your dishes, it makes bubbles.
0:06:58 > 0:06:59Oh, it does, doesn't it? Of course, yes.
0:06:59 > 0:07:01It sort of foams it all up, doesn't it?
0:07:01 > 0:07:04- So that's what we thought.- I like your thinking there. Scientific.
0:07:04 > 0:07:06Now, then. Yellows,
0:07:06 > 0:07:07you've gone for B. Now,
0:07:07 > 0:07:09what's your thinking behind that?
0:07:09 > 0:07:11We think that it'll cause it to swirl
0:07:11 > 0:07:14because all of the liquid hitting it will,
0:07:14 > 0:07:18like, add more liquid to it, so it'll start to turn more liquidy.
0:07:18 > 0:07:19That's very, very good.
0:07:19 > 0:07:21So you think it's going to all swirl
0:07:21 > 0:07:23around in pretty patterns and things.
0:07:23 > 0:07:25Ooh, that would be nice, wouldn't it? Ooh, I hope it is.
0:07:25 > 0:07:29Now, then. Blues, you've gone for B
0:07:29 > 0:07:32as well. Now, what was your thinking there?
0:07:32 > 0:07:36We think that the soap is going to react with the milk.
0:07:36 > 0:07:38So what do you think is going to make it react?
0:07:38 > 0:07:42Cos it's so... It's going to split the liquids.
0:07:42 > 0:07:45Well, that's some pretty fine thinking going on there, I think.
0:07:45 > 0:07:48And what did you think, and are you correct? And are you correct?
0:07:48 > 0:07:49Who's correct?
0:07:49 > 0:07:54Be warned, Boffins! The truth might just melt your milky minds!
0:07:54 > 0:07:55Let's see what happens
0:07:55 > 0:07:59when we actually add the washing up liquid here to the milk.
0:07:59 > 0:08:02In three, two, one...
0:08:02 > 0:08:04Bombs away!
0:08:06 > 0:08:09It looks like a brain! But a messy brain.
0:08:10 > 0:08:12Ooh, look!
0:08:12 > 0:08:13Pretty!
0:08:13 > 0:08:15# Beautiful patterns
0:08:15 > 0:08:17# In the milk of science. #
0:08:17 > 0:08:18Look at that!
0:08:18 > 0:08:21The fat-seeking molecules of the washing up liquid move to the
0:08:21 > 0:08:23fatty parts of the milk. They just love fat.
0:08:23 > 0:08:25They actually bind with the fat,
0:08:25 > 0:08:28making the surface bonds in the milk weaker at these points.
0:08:28 > 0:08:31This allows the surrounding stronger bonds to pull the milk
0:08:31 > 0:08:34away from the washing up liquid, creating this soapy, swirly,
0:08:34 > 0:08:37technicoloured dairy dance.
0:08:37 > 0:08:39That means the amazing answer is B!
0:08:39 > 0:08:44The washing up liquid causes the ink to swirl into the milk.
0:08:44 > 0:08:46So who chose B?
0:08:46 > 0:08:51Yes, the Yellows and the Blues. You'll both get five honour points.
0:08:51 > 0:08:53Well done, you! Yeah, yeah!
0:08:53 > 0:08:55CHEERING AND APPLAUSE
0:08:59 > 0:09:03Now. Next up, our teams get to flex their c-c-creative muscles...
0:09:03 > 0:09:04DOINK!
0:09:04 > 0:09:06..in the creative challenge!
0:09:06 > 0:09:09My fellow thinkers, reboot your brilliant brains
0:09:09 > 0:09:13and get them ready for this!
0:09:13 > 0:09:15You'll need to be as sharp as a clever cutlass for this
0:09:15 > 0:09:18challenge, because dear old Captain Blue-Whiskers here,
0:09:18 > 0:09:20he's got stuck at the end of the plank,
0:09:20 > 0:09:22suspended over water!
0:09:22 > 0:09:25Now, the only way to rescue my little feline friend is to
0:09:25 > 0:09:28travel to the end of the plank and collect him.
0:09:28 > 0:09:32And you'll be asking yourselves, "Where's the science in that?"
0:09:32 > 0:09:37So we've made this sturdy plank more of an unsturdy seesaw.
0:09:37 > 0:09:41Can you brainy buccaneers design a way to safely reach
0:09:41 > 0:09:45Captain Blue-Whiskers without the seesaw plank...
0:09:45 > 0:09:47DOINK!
0:09:47 > 0:09:49..tipping him into the water - wargh, splash!
0:09:49 > 0:09:53Yes, that's one precariously placed pirate puss.
0:09:53 > 0:09:54MEOW!
0:09:54 > 0:09:55Our teams were given two days
0:09:55 > 0:10:01and a budget of £50 to design a solution to this challenge.
0:10:01 > 0:10:05The further GP gets, the more points the team wins.
0:10:05 > 0:10:09Neither GP or Captain Whiskers should touch the water at any point.
0:10:09 > 0:10:11The team whose design allows him
0:10:11 > 0:10:14to reach the cat the fastest will be the winner.
0:10:14 > 0:10:15And here he is!
0:10:15 > 0:10:20Yes, folks, it's the stunt man of science, too fearless to fail,
0:10:20 > 0:10:23too smart to do anything but succeed,
0:10:23 > 0:10:27ready to brave this pirate plank challenge, it's the guinea pig!
0:10:27 > 0:10:30CHEERING
0:10:30 > 0:10:33Ha-ha! Here he comes.
0:10:33 > 0:10:36Good boy. Good boy.
0:10:36 > 0:10:37Now, Guinea Pig,
0:10:37 > 0:10:39I know you like playing pirate games
0:10:39 > 0:10:42but you shouldn't really wear two eye-patches, you know.
0:10:42 > 0:10:43It's very dangerous.
0:10:43 > 0:10:45But, Dr Brain, it's double the pirate fun!
0:10:45 > 0:10:47Ow!
0:10:47 > 0:10:48Ho-ho-ho! Ha-ha!
0:10:48 > 0:10:52Now, then. The challenge must begin!
0:10:52 > 0:10:56First of all, let's see what happens when GP attempts to rescue Captain
0:10:56 > 0:10:58Blue-Whiskers without the help of our brilliant, genius
0:10:58 > 0:11:00scientific minds here.
0:11:00 > 0:11:03Yes, this is what we call the planless plan.
0:11:03 > 0:11:05FANFARE
0:11:05 > 0:11:07Get it, yes! Give him a bit of encouragement.
0:11:07 > 0:11:09Well, as you can see, there is nothing to support him,
0:11:09 > 0:11:13and Guinea Pig is on a one-way ticket going down!
0:11:13 > 0:11:14Hee-hee-hee! Unlucky, Guinea Pig.
0:11:17 > 0:11:19SPLASH
0:11:19 > 0:11:21So let's see what our teams have come up with.
0:11:21 > 0:11:25Now, first of all, it's the Green Brainiacs!
0:11:25 > 0:11:27What's the name of your plan?
0:11:27 > 0:11:30The name of our plan is The Weight of Wonder.
0:11:30 > 0:11:32The Weight of Wonder.
0:11:32 > 0:11:35Dr Krish, what is the guinea pig wearing? What's this all about?
0:11:35 > 0:11:39Guinea Pig is wearing a rucksack, which contains weights...
0:11:39 > 0:11:41Wait, wait! He's got weights on?
0:11:41 > 0:11:43What are you going to do with those weights?
0:11:43 > 0:11:44When he climbs up the plank,
0:11:44 > 0:11:46he's got to drop a little bit of weight...
0:11:46 > 0:11:47Ah.
0:11:47 > 0:11:48..behind him.
0:11:48 > 0:11:51So you're going to spread the weight along the plank
0:11:51 > 0:11:54so it'll all be equal, and hopefully it won't tip.
0:11:54 > 0:11:57The Green team will get Guinea Pig to place the heavy
0:11:57 > 0:11:58bags down as he goes.
0:11:58 > 0:12:00They hope this will spread out the weight evenly,
0:12:00 > 0:12:02and stop the plank from tipping.
0:12:02 > 0:12:04Or will it? Mu-ha-ha-ha!
0:12:04 > 0:12:05CAT MEOWS
0:12:05 > 0:12:07Sorry, I got a bit carried away there.
0:12:07 > 0:12:09Right, Guinea Pig, are you ready?
0:12:09 > 0:12:11I was born ready, Dr Brain!
0:12:11 > 0:12:15Fantastic. Green Brainiacs, are you ready?
0:12:15 > 0:12:16- ALL:- Yes!
0:12:16 > 0:12:17Then let's do it.
0:12:17 > 0:12:19- Here we go. - HORN BLARES
0:12:19 > 0:12:21You've got to tell him what to do. Tell him what to do.
0:12:21 > 0:12:23- Go slowly.- Slowly, slowly, yes.
0:12:23 > 0:12:25- CAT MEOWS - When do you want him
0:12:25 > 0:12:26to put the first weight down?
0:12:26 > 0:12:28THEY TALK When he gets...
0:12:28 > 0:12:30When he gets onto the fulcrum there.
0:12:30 > 0:12:32The pivot, yes.
0:12:32 > 0:12:34There we go. So very gently. That's it.
0:12:34 > 0:12:36Nice, Guinea Pig. Good work.
0:12:36 > 0:12:38- Good.- Where do I put the next one?
0:12:38 > 0:12:41- Yes.- Erm...- Keep walking.- Over that. Keep walking.
0:12:41 > 0:12:43So, at the moment, all his weight is there
0:12:43 > 0:12:45and there's a little weight in the middle. OK.
0:12:45 > 0:12:46How far?
0:12:46 > 0:12:49- Erm...- A two pound...- Yes. - There.
0:12:49 > 0:12:51- HEARTBEAT - OK.- Now this may get...
0:12:51 > 0:12:52SEESAW SQUEAKS
0:12:52 > 0:12:54- Oh!- Oh!
0:12:56 > 0:12:57Unlucky!
0:12:57 > 0:12:59In he goes again.
0:12:59 > 0:13:03I liked your thinking, though, because you were placing the weights
0:13:03 > 0:13:06along the seesaw there to try and make it all equal.
0:13:06 > 0:13:09But what do you think really went wrong there?
0:13:09 > 0:13:12We didn't put the weights first.
0:13:12 > 0:13:14Ah! So they weren't quite in the right place.
0:13:14 > 0:13:17Because, yes, Guinea Pig, of course, is the biggest weight
0:13:17 > 0:13:20and then, as he went along, all the weight went up that end, didn't it?
0:13:20 > 0:13:23- Yeah.- Unlucky there, Green Brainiacs!
0:13:23 > 0:13:25And unlucky, Guinea Pig. Nice try.
0:13:26 > 0:13:29Next up, it's the Yellow Whizzbangers.
0:13:29 > 0:13:30What's your plan called?
0:13:30 > 0:13:32The Sandbag 3,000.
0:13:32 > 0:13:34- ROBOTIC VOICE:- Sandbag 3,000.
0:13:34 > 0:13:37I like that. Now, I can't help but notice
0:13:37 > 0:13:38that you've got something there,
0:13:38 > 0:13:41you've got some sacks of something there. What's in those sacks?
0:13:41 > 0:13:44- Erm, sand.- And what are you hoping that that sand is going to do?
0:13:44 > 0:13:48- We're hoping that it'll weigh the board down.- Yes.
0:13:48 > 0:13:52So that enough weight is produced on the end of the board
0:13:52 > 0:13:55so that Guinea Pig can walk across and save the cat successfully.
0:13:55 > 0:13:59Ah! Possibly what went wrong with the Green Team's plan was
0:13:59 > 0:14:02the weights were evenly distributed, weren't they? Which is fine
0:14:02 > 0:14:03when you're dealing with pressure,
0:14:03 > 0:14:05but this is about turning forces, isn't it?
0:14:05 > 0:14:07So you're going to put them all on one end here
0:14:07 > 0:14:11and hope that that counterbalances the weight of the guinea pig.
0:14:11 > 0:14:13- Is that right? - ALL:- Yeah.
0:14:13 > 0:14:16The Yellow Team are hoping that by placing all the weight down one end,
0:14:16 > 0:14:18- CAT MEOWS - it will be enough to counterbalance
0:14:18 > 0:14:20the weight of Guinea Pig as he moves along the plank.
0:14:20 > 0:14:23- DR BRAIN LAUGHS - Fingers crossed!
0:14:23 > 0:14:24Are you ready, Yellows?
0:14:24 > 0:14:26- ALL:- Yes! - Yes, come on! Let's do it.
0:14:26 > 0:14:29- Guinea Pig, are you ready? - I'm ready, Dr Brain.
0:14:29 > 0:14:30- Go, Guinea Pig! - HORN BLARES
0:14:30 > 0:14:32Now, you can instruct him. So, yes...
0:14:32 > 0:14:34- Put that where your foot is.- King Arthur wants you
0:14:34 > 0:14:38- to put it right at the end. - Right there.- Good plan, my liege.
0:14:38 > 0:14:41- Then pick the next one up.- And then put all of them on the next side.
0:14:41 > 0:14:42How do you want him to do this?
0:14:42 > 0:14:44- All on top of each other, or...? - No. Just all in a line.
0:14:44 > 0:14:47- Or in a pyramid, or...?- Yep. CAT MEOWS
0:14:47 > 0:14:50You need to sort of get a little bit of a move on, I think.
0:14:50 > 0:14:52Otherwise you might find you don't even get on the seesaw.
0:14:52 > 0:14:54Right, OK, you've got the weight on now.
0:14:54 > 0:14:56- HEARTBEAT - So now we're hoping...
0:14:56 > 0:14:58- that this is going to be enough. - CAT MEOWS
0:14:58 > 0:14:59SEESAW CREAKS
0:14:59 > 0:15:02- Oh, no! - ALL:- Oh!
0:15:02 > 0:15:03- DR BRAIN LAUGHS - Oh, no!
0:15:03 > 0:15:04The cat's still on!
0:15:04 > 0:15:08- The cat is still on, but he's in. - LAUGHTER
0:15:08 > 0:15:11Well, that was unfortunate. Now, what do you think went wrong there?
0:15:11 > 0:15:14I think maybe we should have told him to go on his knees.
0:15:14 > 0:15:16- Ah!- Because it wouldn't have been as much weight.
0:15:16 > 0:15:19So you think that if he perhaps spread himself a little bit more...
0:15:19 > 0:15:21- Yeah.- ..that would have spread his weight
0:15:21 > 0:15:23- and he could have reached out to the cat?- Yeah.
0:15:23 > 0:15:26Unlucky, Guinea Pig! How do you feel?
0:15:26 > 0:15:29- Very wet.- Well, you might have to get used to that,
0:15:29 > 0:15:32because it's now time for the Blue Plan!
0:15:34 > 0:15:36Which is what exactly?
0:15:36 > 0:15:39- It's called Roller Rescue.- Ooh, I like that.
0:15:39 > 0:15:43And it's basically going to focus on kind of counterbalance
0:15:43 > 0:15:46with equal weight distribution.
0:15:46 > 0:15:47- Very good.- Yes.
0:15:47 > 0:15:49It looks to me like you've got a skateboard,
0:15:49 > 0:15:52- a box and a guinea pig with giant hands.- Yep.- Yep.
0:15:52 > 0:15:54- THEY LAUGH - Yes.
0:15:54 > 0:15:57- The box is our weight, so... - Ah, right!
0:15:57 > 0:16:00..hopefully it will be enough to make sure that GP
0:16:00 > 0:16:04doesn't fall into the water and it's attached to a skateboard,
0:16:04 > 0:16:07so he can roll out on his front, which will make him longer and,
0:16:07 > 0:16:12- hopefully, his giant hands will be able to grab the kitty.- Ah, I see.
0:16:12 > 0:16:15Yes, because, of course, the seesaw isn't 50-50, is it?
0:16:15 > 0:16:18It's sort of like that, not like that.
0:16:18 > 0:16:20He'll have to not go all the way to the end, won't he,
0:16:20 > 0:16:21- for it to work? - ALL:- Yes.
0:16:21 > 0:16:24The Blue Team have weighed down the far end of the plank
0:16:24 > 0:16:27and are hoping that, by lying down and using the giant hands,
0:16:27 > 0:16:31less of GP's weight will be placed on the tipping point. Interesting!
0:16:31 > 0:16:34Sounds like they kind of know what they're talking about.
0:16:34 > 0:16:35Let's find out if they do!
0:16:35 > 0:16:37- Are you ready? - ALL:- Yeah.
0:16:37 > 0:16:38- Are you ready?- Not really, no.
0:16:38 > 0:16:40- LAUGHTER - Well, get on with it anyway.
0:16:40 > 0:16:42- HORN BLARES - Go, Guinea Pig.
0:16:42 > 0:16:45- You can instruct him. Tell him what to do.- Maybe go on your belly a bit.
0:16:45 > 0:16:49- On your belly, that's it.- Right, now push with your feet.- Here we go.- Ooh.
0:16:49 > 0:16:52- Well, he's not wet so far, so we're all right.- Slowly!
0:16:52 > 0:16:53If you call "cat",
0:16:53 > 0:16:54- he might come to you. - CAT MEOWS
0:16:54 > 0:16:56DR BRAIN LAUGHS, THEY CALL
0:16:56 > 0:16:58- Kitty, kitty!- That's it. SEESAW CREAKS
0:16:58 > 0:17:01That's it, yes. Always give encouragement to a stuffed cat.
0:17:01 > 0:17:02- THEY SHOUT - Oh, oh, oh!- Slowly.
0:17:02 > 0:17:04- HEARTBEAT - Now, now...- Slowly!
0:17:04 > 0:17:06- You've got this, you've got this. - Ooh!
0:17:06 > 0:17:08- Come on, come on, cat!- Ooh, he's nearly got...!
0:17:08 > 0:17:09- THEY SHOUT - He's nearly got the cat!
0:17:09 > 0:17:12- Go on!- Go on, GP! Oh, no. He's starting to tip!
0:17:12 > 0:17:13- THEY SCREAM - No!
0:17:13 > 0:17:15DR BRAIN LAUGHS
0:17:16 > 0:17:18- Oh, dear! - TEAM LAUGHS
0:17:18 > 0:17:20Oh, deary, deary me.
0:17:20 > 0:17:22You had a good theory, but it didn't quite work, did it?
0:17:22 > 0:17:24- ALL:- No. - Unlucky!
0:17:24 > 0:17:27Ha-ha! What a brilliant round that was. I wonder what your plan was.
0:17:27 > 0:17:30Now, all three teams did mentioned the weight,
0:17:30 > 0:17:32which was KIND of what it was all about.
0:17:32 > 0:17:35But what was really all about was counterweight
0:17:35 > 0:17:37and counterbalancing Guinea Pig's weight.
0:17:37 > 0:17:40There, you see. I knew I could COUNT on you.
0:17:40 > 0:17:41Count! Ha-ha!
0:17:41 > 0:17:43Oh, forget it!
0:17:43 > 0:17:45And only two teams spotted that little plan.
0:17:45 > 0:17:47That was the Yellows and the Blues.
0:17:47 > 0:17:49So I've got to award both of those teams
0:17:49 > 0:17:50five points for valiant effort.
0:17:50 > 0:17:52CHEERING
0:17:52 > 0:17:53Well done, Yellows. And well done, Blues.
0:17:53 > 0:17:54APPLAUSE AND CHEERING
0:18:00 > 0:18:02See that? Pretty fast, right?
0:18:02 > 0:18:05Yes, that's right, because this round is all about quick reactions.
0:18:05 > 0:18:07So who will be the quickest?
0:18:07 > 0:18:11Even my amazing monkey vision cannot accurately answer that question,
0:18:11 > 0:18:14which means it's time to bring out...
0:18:14 > 0:18:19- SLOW VOICE:- The Slowmonizer.
0:18:19 > 0:18:22Yes! This super cool camera records in super...
0:18:22 > 0:18:24- SLOW VOICE:- very slow motion,
0:18:24 > 0:18:26so that I can accurately see
0:18:26 > 0:18:28who the winner is going to be.
0:18:28 > 0:18:32Right, my brainy buddies, here's the challenge.
0:18:32 > 0:18:33Dr Seren from the Greens,
0:18:33 > 0:18:35Dr Finlay from the Yellows
0:18:35 > 0:18:38and Dr April from the Blues have been nominated by their teams
0:18:38 > 0:18:40to stand behind these balloons here.
0:18:40 > 0:18:44Now, each of these balloons is filled with shaving foam, you see.
0:18:44 > 0:18:47And on the sound of Dr Brain's sound of the week...
0:18:47 > 0:18:49ROOSTER CALL
0:18:49 > 0:18:52..you must bring up your hands and clap the balloon to burst it.
0:18:52 > 0:18:54The first one to pop their balloon wins the points.
0:18:54 > 0:18:55You got it?
0:18:55 > 0:18:57- ALL:- Yes. - HE LAUGHS
0:19:05 > 0:19:06Ready?
0:19:07 > 0:19:09COCKEREL CROWS
0:19:09 > 0:19:12Wow! Wow! Wow! You were all so quick there.
0:19:12 > 0:19:16Let's take a look at that again. Oh, balloon-mongously pop-tastic.
0:19:16 > 0:19:19There's not a lot between them.
0:19:19 > 0:19:21With my natural monkey vision, I couldn't split you apart at all.
0:19:21 > 0:19:25We're going to have to use the ultimate Slomonizer.
0:19:25 > 0:19:28Let's have a look. Let's see who won. Who was it?
0:19:29 > 0:19:33And here we go. And it's Green is the winner, followed by Blue.
0:19:33 > 0:19:38Oh, look at slowcoach Yellow with custard all over his face. Oh, dear.
0:19:38 > 0:19:42That means it's ten points to the Greens.
0:19:42 > 0:19:43Well done.
0:19:46 > 0:19:49So we clearly see the winner there. It's Green with ten points.
0:19:49 > 0:19:52But what's that done to the scores? Oh, look, they're all level.
0:19:58 > 0:20:03Now it's time for our teams to engage their brains again.
0:20:03 > 0:20:07Yes, it's the Inspiration Challenge.
0:20:07 > 0:20:11Now, one of my many awesome superpowers is the ability to fly.
0:20:11 > 0:20:15I don't use it very often, it's a waste of my excellent boots.
0:20:15 > 0:20:18Now, teams, you're going to have five minutes to design
0:20:18 > 0:20:24and five minutes to build a super-sized aerodynamic craft
0:20:24 > 0:20:26which will be launched from our podium
0:20:26 > 0:20:29on to our Ultimate Brain testing range.
0:20:29 > 0:20:31Did you get that? You happy? You know what you're going to do?
0:20:31 > 0:20:34- ALL:- Yes.- Your time starts...
0:20:34 > 0:20:36now. Get designing, teams.
0:20:36 > 0:20:37KLAXON BLARES
0:20:37 > 0:20:39The Dixi-Chicks are go.
0:20:39 > 0:20:41Our intrepid teams are looking to build
0:20:41 > 0:20:44sleek, slimline flying machines that cut through the air.
0:20:44 > 0:20:47Now, a bit of weight could give them momentum when they get moving
0:20:47 > 0:20:50but too much of it and gravity will take them down.
0:20:50 > 0:20:52Yes, this is aerodynamics in action, folks.
0:20:52 > 0:20:55Smooth, sturdy symmetry and a breathtaking balance of weight
0:20:55 > 0:20:58is what's needed if they really want to go the distance.
0:20:58 > 0:21:00KLAXON BLARES
0:21:00 > 0:21:03Time is up. Stop making, stop building,
0:21:03 > 0:21:05stop creating, stop science-ing.
0:21:05 > 0:21:07Teams, you have designed
0:21:07 > 0:21:10your awesomely aerodynamic flying machines,
0:21:10 > 0:21:13but whose will soar and score the points?
0:21:13 > 0:21:15Let's find out.
0:21:15 > 0:21:18Here we are. What's the thinking behind your plan here?
0:21:18 > 0:21:22It's in the shape of an aeroplane and we've also got the feathers
0:21:22 > 0:21:27because, on a bird, the feathers are used to help it fly.
0:21:27 > 0:21:30- Now, are you confident that it's going to fly?- Erm...
0:21:30 > 0:21:31You're not sure.
0:21:31 > 0:21:34Dr Krish, what do you think's gone wrong in your design?
0:21:34 > 0:21:36- There aren't any wings.- Yes.
0:21:36 > 0:21:39Do you think maybe it might not go as far as you'd hoped
0:21:39 > 0:21:41- without the wings?- Yeah. - You never know, do you?
0:21:41 > 0:21:45Miracles can happen in science. Well, shall we see if it works?
0:21:45 > 0:21:47That's right. Dr Seren, if you wouldn't mind
0:21:47 > 0:21:49going up to launch centre.
0:21:49 > 0:21:51Now, then, we want to see how far it goes
0:21:51 > 0:21:57and Guinea Pig will mark where your super-aerodynamic structure lands.
0:21:57 > 0:21:59In three, two,
0:21:59 > 0:22:01one, lift off.
0:22:01 > 0:22:02Oh! Oh! Oh! Oh!
0:22:02 > 0:22:04CHICKENS SQUAWK
0:22:04 > 0:22:08I'm not sure how far that is. What do you think happened there?
0:22:08 > 0:22:10It didn't fly very well.
0:22:10 > 0:22:13The Greens went slim and lightweight
0:22:13 > 0:22:15but, without any wings to take advantage of the air,
0:22:15 > 0:22:18it was easy for air resistance to push it round
0:22:18 > 0:22:21into an unstoppable tumble.
0:22:21 > 0:22:26Well done, you, Green Braniacs. Let's see what the Yellows have got.
0:22:26 > 0:22:29Now, what's the theory behind your design?
0:22:29 > 0:22:31Well, because it can't really glide,
0:22:31 > 0:22:34- we're just going to try and throw it as far as we can.- Oh, I see.
0:22:34 > 0:22:38In technical terms, "I'm go to chuck it, mate, and see where it goes."
0:22:38 > 0:22:40Right, well, shall we see if it works?
0:22:40 > 0:22:41King Arthur, up you go.
0:22:41 > 0:22:45Now, you've got to beat the Green team there.
0:22:45 > 0:22:47Are you ready? Three, two,
0:22:47 > 0:22:49one, lift off.
0:22:49 > 0:22:51Oh! Look at that!
0:22:51 > 0:22:55Ho-ho-ho! That's pretty good.
0:22:55 > 0:22:57You've actually gone out of the studio.
0:22:57 > 0:23:00I think it may even have gone into space.
0:23:00 > 0:23:02Now, why do you think it did so well?
0:23:02 > 0:23:05I think because it kind of just, like, shot straight through the air.
0:23:05 > 0:23:08Like a Frisbee, it's quite hard so you had the hard bit in the middle.
0:23:08 > 0:23:11- Ah, yes.- Then that slices through the air when you throw it.
0:23:11 > 0:23:14So it had lots of nice lift because of the shape of it.
0:23:14 > 0:23:16We put a coat hanger in it and then wrapped the paper round it.
0:23:16 > 0:23:19Ah, yes. I was a little worried that the coat hanger
0:23:19 > 0:23:21was going to weigh it down but, actually,
0:23:21 > 0:23:22I think your design was so good,
0:23:22 > 0:23:25it actually gave it momentum, didn't it?
0:23:25 > 0:23:27With the rigid frame of the coat hanger
0:23:27 > 0:23:29and a thin cover of lightweight paper,
0:23:29 > 0:23:32the Yellows' design had momentum and very low air resistance.
0:23:32 > 0:23:34The spin of their Frisbee throw added stability
0:23:34 > 0:23:36to their phenomenal flight.
0:23:36 > 0:23:39- You must be pretty pleased with yourselves, lads.- ALL:- Yeah.
0:23:39 > 0:23:41Well done, you. Well done, Yellows.
0:23:41 > 0:23:43Well, let's see if the Blues can do any better.
0:23:46 > 0:23:49Well, Blues. What's your design here?
0:23:49 > 0:23:50We have here the Dixi Jet
0:23:50 > 0:23:53and, basically, for it to be dynamic through the air,
0:23:53 > 0:23:56we wanted to make a kind of triangle shape
0:23:56 > 0:23:58so that there's a point so the air can just...
0:23:58 > 0:24:01- Thrust, that is. You want to give it some thrust.- Yep.- Very good.
0:24:01 > 0:24:04And we want it to be really smooth so we don't have anything on there
0:24:04 > 0:24:06and we've got the feathers here at the back.
0:24:06 > 0:24:08Hope they're going to sort of cut through the air
0:24:08 > 0:24:10and give it lots of lift, is that right?
0:24:10 > 0:24:12Well, I think you've done pretty well there.
0:24:12 > 0:24:15This could be interesting. It could be a close one, folks.
0:24:15 > 0:24:17- Shall we see it in action?- ALL:- Yes.
0:24:17 > 0:24:19- Who's going to launch?- Go, Jordan!
0:24:19 > 0:24:21Dr Jordan. There she goes.
0:24:21 > 0:24:23We believe in you, Jordan.
0:24:23 > 0:24:25Here we go. Are you ready?
0:24:25 > 0:24:27In three,
0:24:27 > 0:24:28two,
0:24:28 > 0:24:31one, lift off.
0:24:31 > 0:24:33CLANG
0:24:33 > 0:24:37Well, it did move through the air.
0:24:37 > 0:24:39It sort of went backwards, didn't it?
0:24:39 > 0:24:41Well, unlucky, Blues.
0:24:41 > 0:24:44The Blues went for a classic paper aeroplane design
0:24:44 > 0:24:48but the huge flippy-flappy structure made it bend too much
0:24:48 > 0:24:50when it hit lots of incoming air,
0:24:50 > 0:24:54acting like a giant parachute in a slow downward spiral.
0:24:54 > 0:24:57I think we know who the winner of that round was, don't we?
0:24:57 > 0:24:59Yes, it's the Yellows.
0:24:59 > 0:25:03Now, as the final round approaches, let's find out what the score is
0:25:03 > 0:25:07with a little thing I call the scores.
0:25:07 > 0:25:09The Yellows storm ahead on 20, but I'm feeling generous,
0:25:09 > 0:25:12so it's five points each to the Blues and Greens
0:25:12 > 0:25:14for their sciencey thinking.
0:25:14 > 0:25:15With plenty of points still to play for,
0:25:15 > 0:25:19it's anyone's game on Ultimate Brain.
0:25:19 > 0:25:22And now, the greatest mind-boggling challenge
0:25:22 > 0:25:24ever to be faced by man or monkey.
0:25:24 > 0:25:26More nerve-racking than traversing an active volcano,
0:25:26 > 0:25:29more thrilling than a lightspeed rollercoaster,
0:25:29 > 0:25:32more daunting than matching up all your odd socks before bedtime,
0:25:32 > 0:25:34yes, it's the Quickfire Round.
0:25:39 > 0:25:42Now, teams, hands on your brains.
0:25:42 > 0:25:45Are you ready? Remember, you get two points for each correct answer
0:25:45 > 0:25:48but you get nothing, not even a single fluff-covered jelly bean
0:25:48 > 0:25:53- from Guinea Pig's pocket for a wrong answer. Shall we do it?- ALL:- Yes.
0:25:53 > 0:25:55Here we go. Your time starts...
0:25:55 > 0:25:57now!
0:25:57 > 0:26:00What is the largest planet in our solar system?
0:26:00 > 0:26:02Yellows.
0:26:02 > 0:26:03Jupiter.
0:26:03 > 0:26:05Is the right answer.
0:26:05 > 0:26:10True or false, carnivorous plants can eat a whole human child?
0:26:10 > 0:26:12- Yellows.- True.
0:26:12 > 0:26:13It's false.
0:26:13 > 0:26:18Which famous Stephen wrote a book - The Brief History of Time?
0:26:18 > 0:26:19Blues.
0:26:19 > 0:26:20Stephen Hawking.
0:26:20 > 0:26:22Very good.
0:26:22 > 0:26:27A palaeontologist would be more likely to study what?
0:26:27 > 0:26:28Blues.
0:26:28 > 0:26:31- Bones.- Fossils.- Fossils. Dinosaur bones.
0:26:31 > 0:26:32It's right.
0:26:32 > 0:26:33BEEPING
0:26:33 > 0:26:37Time up! That was some seriously super-smart quickfire action there.
0:26:37 > 0:26:39The Blue team buzzed, the Yellow team yelled,
0:26:39 > 0:26:41the Green team were mean on the answer scene,
0:26:41 > 0:26:44but who, out of your marvellous minds, is the winner?
0:26:44 > 0:26:48It's time for the results.
0:26:48 > 0:26:50In third place with 15 points,
0:26:50 > 0:26:53it's the Green team.
0:26:53 > 0:26:54Well done.
0:26:54 > 0:26:5615, very good.
0:26:56 > 0:26:58In second place with 19 points,
0:26:58 > 0:27:00it's the Blue team.
0:27:02 > 0:27:06But our Ultimate Brain winners with 22 points,
0:27:06 > 0:27:09it's the Yellows.
0:27:13 > 0:27:14Well done, you lot.
0:27:14 > 0:27:18- Wow, they were amazing, right? - They were wickedly amazing.
0:27:18 > 0:27:20Astonishing staff. Fantastic, indeed.
0:27:20 > 0:27:24All three teams have shown some seriously scientific pizzazz today.
0:27:24 > 0:27:25If it's honour you're after,
0:27:25 > 0:27:28then it's Ultimate Brain honour you've won.
0:27:28 > 0:27:32Salute the victors, teams. Well done! Yes! See you next time
0:27:32 > 0:27:34for more brain-expanding excellent experiments,
0:27:34 > 0:27:38all on...Ultimate Brain!
0:27:41 > 0:27:42Marvellous!
