0:00:11 > 0:00:14How can you hide a handsome monkey using only liquid nitrogen
0:00:14 > 0:00:15and hot water?
0:00:15 > 0:00:18And will the 4 O'Clock Club achieve full marks for a change?
0:00:18 > 0:00:24You'll need to run your brain at full power to be the Ultimate Brain!
0:00:28 > 0:00:29CHEERING AND APPLAUSE
0:00:33 > 0:00:36Welcome to Ultimate Brain!
0:00:36 > 0:00:42I am on a quest to seek out the sharpest tools in the box.
0:00:42 > 0:00:44Yes, great, pulsing brains,
0:00:44 > 0:00:48steaming and bubbling over with knowledge and intelligence.
0:00:48 > 0:00:49For I...
0:00:49 > 0:00:52- ECHOING:- ..am Dr Brain!
0:00:53 > 0:00:57These people over here think they're some pretty clever cookies
0:00:57 > 0:01:01and they will be battling it out for the ultimate prize - honour.
0:01:01 > 0:01:05Let's find out who they are. Beginning with the Green Team!
0:01:06 > 0:01:09Our first team are Rhodri, Megan and Alex,
0:01:09 > 0:01:11otherwise known as the Green Machines!
0:01:11 > 0:01:13Let's see if their brains are running like clockwork.
0:01:13 > 0:01:14- Hi, Greens!- Hello.
0:01:14 > 0:01:16- Where are you from? - ALL:- Swansea.
0:01:16 > 0:01:19- Swansea? That's in Wales, right? - Yes.
0:01:19 > 0:01:22Lovely place. What's the cleverest thing you've ever done?
0:01:22 > 0:01:23Be on this show.
0:01:23 > 0:01:26"Be on this show" is a great answer.
0:01:26 > 0:01:28Ladies and gentlemen, the Green Machine!
0:01:28 > 0:01:30CHEERING AND APPLAUSE
0:01:31 > 0:01:33Our next team, Lidia, Imogen and Erin, have called themselves
0:01:33 > 0:01:35the Yellow Experimenters.
0:01:35 > 0:01:38Let's hope their method leads them to the right conclusions.
0:01:38 > 0:01:40- Where are you from? - Birmingham.
0:01:40 > 0:01:47Birmingham! Ah, I like Birmingham. Dr Lidia, are you at all sporty?
0:01:47 > 0:01:50- Yeah.- Yes! I thought so. What do you do?- Netball.
0:01:50 > 0:01:52Netball. Anything else?
0:01:52 > 0:01:55- Basketball.- Oh, I'm an expert at basketball....
0:01:55 > 0:01:56Dddddrrrrppp! Swoooosh!
0:01:56 > 0:01:57- Anything else?- Gymnastics.
0:01:57 > 0:01:59Gymnastics? Oh, yes, I'm brilliant at that.
0:01:59 > 0:02:00Aah!
0:02:00 > 0:02:03- Is there a sport you don't play? - Hockey.
0:02:03 > 0:02:05Hockey! She doesn't like hockey.
0:02:05 > 0:02:07I don't like hockey - who'd want to play hockey?
0:02:07 > 0:02:10Well done, you lot! That's the Yellow Team!
0:02:13 > 0:02:15Our final team are the Four O'Clock Blues.
0:02:15 > 0:02:20Ruby, Khalil and Akai from CBBC's hugely popular Four O'Clock Club.
0:02:20 > 0:02:23Can they surprise us all and go to the top of the class?
0:02:23 > 0:02:27Now, these people are usually held back in detention, of course.
0:02:27 > 0:02:29Are you going to be held back today?
0:02:29 > 0:02:32Or are you going to surge forward to victory?
0:02:32 > 0:02:34Obviously we're going to surge forward to victory.
0:02:34 > 0:02:39Now, I've heard, Mr Akai, you're a pretty hot dancer, right?
0:02:39 > 0:02:41Yeah, I'm decent, yeah, yeah.
0:02:41 > 0:02:43- Going to prove it? - Right now?
0:02:43 > 0:02:45- Yes!- OK.
0:02:45 > 0:02:49Come on! Everybody, let's see Akai busting some moves.
0:02:49 > 0:02:51Some music, please!
0:02:51 > 0:02:53ELECTRONIC MUSIC PLAYS
0:02:58 > 0:03:00Thank you!
0:03:00 > 0:03:02Thank you, Akai! Wonderful!
0:03:02 > 0:03:04Well, now all of you, throughout
0:03:04 > 0:03:07this show you've got to try to impress me with your brain skills,
0:03:07 > 0:03:09your intuition and your intelligence.
0:03:09 > 0:03:10But above all...
0:03:10 > 0:03:13- COCKNEY ACCENT:- Don't be a muppet, do you know what I mean?
0:03:13 > 0:03:17Time to stoke up your thinking irons with a nice simple question.
0:03:18 > 0:03:21Look what I have here.
0:03:21 > 0:03:25I have two flasks of liquid nitrogen.
0:03:25 > 0:03:27One of the coldest things on the Earth.
0:03:27 > 0:03:31Colder than the North Pole and the South Pole put together.
0:03:31 > 0:03:34It's close to minus 200 degrees.
0:03:34 > 0:03:36TEETH CHATTERING
0:03:36 > 0:03:39That's cold.
0:03:39 > 0:03:43In contrast, in here I have some boiling water, which is roughly
0:03:43 > 0:03:46round about 100 degrees Centigrade.
0:03:46 > 0:03:50So, what's going to happen when I add the two liquids together?
0:03:50 > 0:03:54Some sort of reaction, I shouldn't doubt. What do we think?
0:03:54 > 0:03:56So the options are...
0:04:07 > 0:04:09What do you think? Have a little chat...now!
0:04:11 > 0:04:14Ah, now, the teams' brains are working hard here,
0:04:14 > 0:04:16considering the possibilities.
0:04:16 > 0:04:19Or are they talking about what they're going to have for tea?
0:04:19 > 0:04:21OK, teams, I think you've had enough time to think -
0:04:21 > 0:04:23let's see your answers...now!
0:04:25 > 0:04:28'Oooh! Each team has gone for a different answer.
0:04:28 > 0:04:30'Four O'Clock Blues have gone for A, the water freezes instantly.
0:04:30 > 0:04:33'The Green Machines have B, the liquid nitrogen boils into a gas.
0:04:33 > 0:04:36'And the Yellow Experimenters have gone for D, something else.
0:04:36 > 0:04:38'What about poor old C?'
0:04:38 > 0:04:41We don't think it's going to freeze straight away,
0:04:41 > 0:04:43we think that it's going to take a few more seconds
0:04:43 > 0:04:45and it's just going to cool down instead of freezing.
0:04:45 > 0:04:50Aah! So you think that the coldness of the liquid nitrogen is going
0:04:50 > 0:04:53to cause the boiling water to just sort of cool down
0:04:53 > 0:04:56- but not quite so far as freezing? - They're wrong.
0:04:56 > 0:05:00Aahhh, I see. Oh, they're wrong, are they, Dr Khalil? They're wrong?
0:05:00 > 0:05:01Come on, then, why?
0:05:01 > 0:05:04- Well, you see the liquid nitrogen, as you said...- Yes.
0:05:04 > 0:05:06- ..is minus 200 degrees, right?- Yes.
0:05:06 > 0:05:09- And the water, you said, is around 100 degrees.- That's right.
0:05:09 > 0:05:11If water's freezing point is 0 degrees,
0:05:11 > 0:05:14then minus 100 degrees would like, it would go to that straight away,
0:05:14 > 0:05:16so it wouldn't gradually go.
0:05:16 > 0:05:18Thinking mathematically, I like that, Blue Team.
0:05:18 > 0:05:20That's very, very good.
0:05:20 > 0:05:23The Green Machines, you've gone for B. Now, what makes you think that?
0:05:23 > 0:05:27- Because steam's a gas, because it rises up with the particles.- Yes.
0:05:27 > 0:05:29And so liquid nitrogen,
0:05:29 > 0:05:33- if it will go in, we think it might rise up with the steam.- Ah!
0:05:33 > 0:05:35So you think it's going to go in there
0:05:35 > 0:05:38and the steam of the water is going to push the liquid nitrogen
0:05:38 > 0:05:41upwards, so that's going to cause it to boil with the steam.
0:05:41 > 0:05:43- Is that, is that what you're saying? - Yeah.
0:05:43 > 0:05:45What a fascinating answer that is.
0:05:45 > 0:05:49There's only one way to find out if it's true - let's try it!
0:05:49 > 0:05:51Here goes science...
0:06:00 > 0:06:02I deem this experiment to be...
0:06:02 > 0:06:04A SUCCESS!
0:06:04 > 0:06:07So there we go, what happens?
0:06:07 > 0:06:09- It turned into gas.- It turned into a gas, steam, and it....
0:06:09 > 0:06:10- It boiled, didn't it?- Yeah.
0:06:10 > 0:06:13The liquid nitrogen boiled, it turned into a gas.
0:06:13 > 0:06:16Which means the correct answer was B.
0:06:16 > 0:06:17And here's the reason why.
0:06:17 > 0:06:21The liquid nitrogen is only just below its boiling point,
0:06:21 > 0:06:23which is minus 196 degrees Celsius.
0:06:23 > 0:06:27Whereas the water is at around 100 degrees Celsius,
0:06:27 > 0:06:29which is way above its freezing point.
0:06:29 > 0:06:32So the nitrogen quickly boils off into a burst of gas before
0:06:32 > 0:06:37the water has had a chance to cool down enough to freeze, do you see?
0:06:37 > 0:06:39Do you see? Do you?
0:06:39 > 0:06:42Which means ten points go to the Green Machines!
0:06:42 > 0:06:43CHEERING AND APPLAUSE
0:06:45 > 0:06:48Challenge number two! The creative challenge!
0:06:50 > 0:06:56Time now to use a different part of the brain. Behold!
0:07:00 > 0:07:03Now, I don't know about you, but I've always wondered,
0:07:03 > 0:07:07ever since I was a little, tiny baby monkey, whether or not you could
0:07:07 > 0:07:11burst this amount of balloons inside one minute.
0:07:11 > 0:07:17So I gave our contestants three days and a budget of £50
0:07:17 > 0:07:19to see if they can work out if it's possible.
0:07:19 > 0:07:22But who's going to be in charge of popping all these balloons?
0:07:22 > 0:07:25Well, I had a little think about that and I thought, why not
0:07:25 > 0:07:30pick somebody who has a deep psychological fear of loud noises?
0:07:30 > 0:07:33MUSIC: "What Makes You Beautiful" by One Direction
0:07:46 > 0:07:52Yes! It's my good friend, my pet, Mr Guinea Pig!
0:07:52 > 0:07:54CHEERING AND APPLAUSE
0:08:02 > 0:08:05You know how I feel about balloons.
0:08:05 > 0:08:08I do. They worry you, don't they?
0:08:08 > 0:08:09They really do.
0:08:09 > 0:08:12- They make you scared, don't they? - Almost as scared as your face, yeah.
0:08:12 > 0:08:14Yes, yes, yes, and do you know what?
0:08:14 > 0:08:16There's nothing that makes me laugh
0:08:16 > 0:08:19more than seeing you frightened and injured. So!
0:08:19 > 0:08:22Now, we need to know what's going to be the first plan of how
0:08:22 > 0:08:24you are going to pop all these balloons.
0:08:24 > 0:08:27So let us ask the Blue Team!
0:08:28 > 0:08:31The Four O'Clock Blues, Ruby, Khalil and Akai.
0:08:31 > 0:08:33Khalil won a BAFTA for his
0:08:33 > 0:08:34performance in The Four O'Clock Club.
0:08:34 > 0:08:38Will his team's idea for this challenge be just as award-winning?
0:08:38 > 0:08:42Now, Dr Ruby, can you talk me through this contraption?
0:08:42 > 0:08:43What do all the parts do?
0:08:43 > 0:08:45- OK, so it's inspired by a crab. - Oh, yes.
0:08:45 > 0:08:47Hence the pincers, they're supposed to be pincers.
0:08:47 > 0:08:49I see, these are pincers.
0:08:49 > 0:08:51What seaside have you been to and seen crabs that look like this?
0:08:51 > 0:08:53It resembles a crab to me.
0:08:53 > 0:08:57OK, and then we have the cone, which has pins in it.
0:08:57 > 0:08:58Oh, and it's a Hoover as well,
0:08:58 > 0:09:02so like, it pulls it in and then it, what's it called? It pierces it.
0:09:02 > 0:09:04- I see.- And you expect that to work?
0:09:04 > 0:09:06Yeah, it's going to work, we're clever, we're doctors.
0:09:06 > 0:09:08You're doctors? You're real doctors, are you?
0:09:08 > 0:09:12Yeah, I done my doctorate in... balloon science.
0:09:12 > 0:09:14In balloon science? OK.
0:09:14 > 0:09:16The Four O'Clock Blues hope that their crab-like,
0:09:16 > 0:09:19vacuum-powered balloon destroyer will suck up the balloons
0:09:19 > 0:09:24at an enormous rate and swiftly despatch them to balloon heaven.
0:09:24 > 0:09:27Sounds potty to me, but will it work?
0:09:27 > 0:09:29- Are we ready to count him in? - Yeah, yeah.- Here we go.- Let's go.
0:09:29 > 0:09:32ALL: Three! Two! One!
0:09:32 > 0:09:34Good luck, Guinea Pig! Off you go!
0:09:36 > 0:09:39No balloons so far. That's a score of nil. Still nothing.
0:09:45 > 0:09:47- That's it, now it's working.- Yes! Yes!
0:09:47 > 0:09:49Oh! And he's broken it!
0:09:49 > 0:09:53Oh, Guinea Pig, you've got to keep going, keep going, come on!
0:09:55 > 0:09:59That's it, you've only got about another 150 to go.
0:10:00 > 0:10:02Keep going! Come on!
0:10:02 > 0:10:03Two!
0:10:04 > 0:10:09Oh, that's it, then, time up, time up, I'm afraid.
0:10:09 > 0:10:11Ah, unlucky with that, really put some effort in there.
0:10:11 > 0:10:14- Well, it sort of worked quite well, didn't it? At points.- Yep.
0:10:14 > 0:10:17- What do you think went wrong?- The Guinea Pig's efforts were shocking.
0:10:17 > 0:10:20- Yeah.- You think so?- You ought to be ashamed of yourself, mate.
0:10:20 > 0:10:22That's because your crab is shocking! That's why!
0:10:22 > 0:10:25- It did fall off, so...- You're blaming him, he's blaming you.
0:10:25 > 0:10:28Yeah, it did fall off, but a good workman never blames his tools.
0:10:28 > 0:10:30- I'm blaming YOUR tools! - That is true.
0:10:30 > 0:10:33It's not my tools, I wouldn't have made this ridiculous space crab.
0:10:33 > 0:10:35Listen, we had £50, all right? Times are hard.
0:10:35 > 0:10:38So are you disappointed that it didn't work?
0:10:38 > 0:10:40Well, it did work, we saw it pop the balloons.
0:10:40 > 0:10:42I don't know if you remember,
0:10:42 > 0:10:44the objective was 200 balloons in 60 seconds.
0:10:44 > 0:10:47- Let's count how many are left... - GIBBERISH
0:10:47 > 0:10:48LOADS!
0:10:48 > 0:10:51Yeah, at the end of the day it's the effort that counts, innit?
0:10:51 > 0:10:52If you had made more effort,
0:10:52 > 0:10:55perhaps I would have been able to do all of them.
0:10:55 > 0:10:58Unfortunately, at the end of the day, it's winning that counts,
0:10:58 > 0:10:59and you didn't.
0:10:59 > 0:11:02You got it wrong, I'm afraid, so no points for the Blue Team.
0:11:02 > 0:11:03Wow!
0:11:03 > 0:11:06Let's see how the Greens get on.
0:11:07 > 0:11:10The Green Machines - Rhodri, Megan and Alex.
0:11:10 > 0:11:13Three of Swansea's finest young minds.
0:11:13 > 0:11:15Rhodri enjoys fencing in his spare time -
0:11:15 > 0:11:17I wonder if he fancies coming round to fix my fence?
0:11:17 > 0:11:19Come on!
0:11:19 > 0:11:22What, pray, is the name of your plan?
0:11:23 > 0:11:24ALL: Operation Buzz Buzz.
0:11:24 > 0:11:28Operation Buzz Buzz? And could that be because he looks like a bee?
0:11:28 > 0:11:29Yeah, completely.
0:11:29 > 0:11:31Ah, there you see, I'm clever, I'm a scientist, you see?
0:11:31 > 0:11:33Now, explain to me how this is going to work.
0:11:33 > 0:11:37I can't see any sort of popping material, will you show me?
0:11:37 > 0:11:39The pins are, like, all over the chest.
0:11:39 > 0:11:42Oh, I see, yes, there's little pins there, aren't there?
0:11:42 > 0:11:44Yes. Come on! Anybody want to high-five him?
0:11:44 > 0:11:47Uh, no, I don't think so, because look, more pins.
0:11:47 > 0:11:49Ooh, ahh, yes, more pins, you see.
0:11:49 > 0:11:51I'm covered in sharp needles
0:11:51 > 0:11:54- and I've got to dive into balloons that make very loud noises?- Yeah!
0:11:54 > 0:11:56Basically yes, yes.
0:11:56 > 0:11:57- Enjoy!- Your favourite hobby.
0:11:57 > 0:12:01It's called confronting your fears. You feel happy?
0:12:01 > 0:12:04- Why don't you do it? - Because you're the Guinea Pig.
0:12:04 > 0:12:05Operation Buzz Buzz.
0:12:05 > 0:12:09A square prickly bee on a mission - is this a more efficient way
0:12:09 > 0:12:11of quickly popping all those balloons in 60 seconds?
0:12:11 > 0:12:13Or will there be a sting in the tale?
0:12:13 > 0:12:15Do you get it? Sting?
0:12:15 > 0:12:18- Hey! Blues and Yellows, do you think this is going to work?- No!
0:12:18 > 0:12:19No! Why not?
0:12:19 > 0:12:20Cheers, guys!
0:12:20 > 0:12:22Because it's rubbish!
0:12:22 > 0:12:26Because it's rubbish, they say. Let's have a go!
0:12:26 > 0:12:27So are you ready?
0:12:27 > 0:12:30- I'm never ready. - Are you ready?- Yes!
0:12:30 > 0:12:3460 seconds on the clock, starting from now!
0:12:36 > 0:12:37There's one, there's another.
0:12:37 > 0:12:40Ooh, it's working quite well, it's working quite well.
0:12:45 > 0:12:47Keep going! You can do it!
0:12:47 > 0:12:49You need to get those balloons.
0:12:49 > 0:12:51Come on! Jump, jump around!
0:12:51 > 0:12:53Jump on that one! Don't stop!
0:12:55 > 0:12:56Five seconds left.
0:12:57 > 0:12:59Jump, jump! Jump over there!
0:13:00 > 0:13:02Oh, that's your time up!
0:13:03 > 0:13:05I can't help feeling that
0:13:05 > 0:13:08if he'd done that dive from the beginning he might have done better.
0:13:08 > 0:13:11- Yeah!- But you did quite well, didn't you? Looking at it.
0:13:11 > 0:13:12How do you feel about how that went?
0:13:12 > 0:13:14I think that went very, very well.
0:13:14 > 0:13:16We did better than the Blues.
0:13:16 > 0:13:18Yeah, but you didn't get 200.
0:13:18 > 0:13:21You didn't get 200, you got 0 points technically.
0:13:21 > 0:13:22We still did better than you.
0:13:22 > 0:13:24Now, let's see how many balloons were left...

0:13:26 > 0:13:31Remembering that the Blue Team had loads left. There are quite a few,
0:13:31 > 0:13:34so I think you've done slightly better than the Blues.
0:13:34 > 0:13:37But will that be enough to secure the points?
0:13:37 > 0:13:41Will the Yellows do any better? Hey! Let's find out!
0:13:41 > 0:13:44Lidia, Imogen and Erin the girl power behind the
0:13:44 > 0:13:45Yellow Experimenters.
0:13:45 > 0:13:48Erin once decided to make four big cakes in a week,
0:13:48 > 0:13:50that's my kind of experiment.
0:13:50 > 0:13:52That's just a snack for me.
0:13:52 > 0:13:55For the Yellows this is your chance to steal the ten points.
0:13:55 > 0:13:57- Are you confident? - Yes, of course.
0:13:57 > 0:13:59What is the name of your plan?
0:13:59 > 0:14:01The Balloon-tastic-popper.
0:14:01 > 0:14:03It involves something quite scary-looking.
0:14:03 > 0:14:05- What is that. please?- Fire.
0:14:05 > 0:14:10- Fire! A blowtorch, is it? Am I right in thinking?- Yeah.
0:14:10 > 0:14:11So how's this going to work?
0:14:11 > 0:14:14Well, it's just going to pop all the balloons.
0:14:14 > 0:14:16It's just going to burn them all?
0:14:16 > 0:14:18It's going to disintegrate them.
0:14:18 > 0:14:21I see. Disintegrate them? Oh, very good, how do you feel about that?
0:14:21 > 0:14:24Now, you're giving me more sharp pins, but this time with fire.
0:14:24 > 0:14:26How much more dangerous do you want to make this for me?
0:14:26 > 0:14:28The Balloon-tastic popper!
0:14:28 > 0:14:31A blowtorch with extra pins for use in the event of flame loss.
0:14:31 > 0:14:35Will this son of Smaug burn the opposition to a crisp?
0:14:35 > 0:14:38Pins and fire, what a wonderful combination.
0:14:38 > 0:14:42Now, I should just say that if you at home were thinking at any point
0:14:42 > 0:14:45of using a blowtorch to set fire to 200 balloons -
0:14:45 > 0:14:46DON'T!
0:14:46 > 0:14:49Now, then, shall we count him in? Are you ready?
0:14:49 > 0:14:52- Yeah.- 60 seconds on the clock. What do you think, Greens and Blues?
0:14:52 > 0:14:57- Is this going to work?- No!- No?- Yes, it will.- Let's try it, here we go!
0:14:57 > 0:15:01Three! Two! One! Go!
0:15:01 > 0:15:05Go on, Guinea Pig! There's one, there's two! Is it working?
0:15:15 > 0:15:17Looking worried, Blue and Green teams.
0:15:17 > 0:15:20- Oh, no!- Oh, no, the gas has gone out, you've got to carry on,
0:15:20 > 0:15:21you've got to carry on!
0:15:21 > 0:15:22It's just a setback.
0:15:24 > 0:15:26Do that! Do that!
0:15:31 > 0:15:35Only one second left! Oh, and that's your time up!
0:15:35 > 0:15:40That is your time up. Well, how do we think that went?
0:15:40 > 0:15:42Good! All right!
0:15:42 > 0:15:43Guinea Pig, how was it?
0:15:43 > 0:15:46Whoo! Well, I had a pop at it!
0:15:46 > 0:15:49You had a pop at it! Very good! Shut up.
0:15:49 > 0:15:50How do you think it went?
0:15:50 > 0:15:54I think it went quite well considering the gas turned off.
0:15:54 > 0:16:00So now I can reveal the exact numbers of who popped what!
0:16:00 > 0:16:01In third place...
0:16:01 > 0:16:05the Four O'Clock Blues with 21 balloons popped.
0:16:05 > 0:16:06Not bad, well done.
0:16:06 > 0:16:07In second place...
0:16:08 > 0:16:13..the Green Machine with 86 balloons popped. Well done.
0:16:13 > 0:16:17And, in first place, that means the Yellow Experimenters
0:16:17 > 0:16:22who popped 105 balloons. So it's ten points for the Yellows!
0:16:22 > 0:16:24Well done! Well done!
0:16:24 > 0:16:25How do you feel?
0:16:25 > 0:16:28- Awesome!- Awesome!
0:16:28 > 0:16:29So at the end of that round,
0:16:29 > 0:16:32the Green Machines and the Yellow Experimenters
0:16:32 > 0:16:34are both in the lead with ten honour points each,
0:16:34 > 0:16:37while the 4 O'Clock Blues are at the bottom of the class again!
0:16:37 > 0:16:39Oh, dearie me.
0:16:39 > 0:16:42Let's see what happens next!
0:16:42 > 0:16:44Now it's time for our teams to act on instinct.
0:16:44 > 0:16:46It's the Brainless Challenge.
0:16:46 > 0:16:50"I like nonsense, it wakes up the brain cells" - Dr Seuss.
0:16:50 > 0:16:53Yes, and it's time now to wake up the bonkers part of the brain.
0:16:53 > 0:16:55The part of the brain known as the...
0:16:55 > 0:16:57- AWOOGA! - ..segment.
0:16:57 > 0:17:01So this game is called Egg Boxing. And I'll tell you why.
0:17:01 > 0:17:02One member of each team
0:17:02 > 0:17:06will be feeding another member of their team eggs.
0:17:06 > 0:17:09They will be carrying it over to another member of their team,
0:17:09 > 0:17:11who will be storing the eggs.
0:17:11 > 0:17:14The only complication is that this member of the team
0:17:14 > 0:17:16has to carry the eggs using...
0:17:16 > 0:17:19- DRUM ROLL - Boxing gloves!
0:17:19 > 0:17:21Give us a couple of shots, come on! Come on!
0:17:21 > 0:17:23That's it! That's it! Yeah, right, left! Right, left, left!
0:17:23 > 0:17:24Good shots there you see.
0:17:24 > 0:17:27So, now, the first one to get all their eggs from the box
0:17:27 > 0:17:31into the pot wins the game and gets ten points, are you ready?
0:17:31 > 0:17:34- Yeah.- Your time starts...now!
0:17:34 > 0:17:38Here we go! Here we go! Oh, look.
0:17:39 > 0:17:43Rhodri is already off, very gently, that's it, lovely.
0:17:43 > 0:17:45The Blues are a little behind, oh,
0:17:45 > 0:17:48but they're going for a sort of bulk move.
0:17:48 > 0:17:50They're trying to get them all in, in one go.
0:17:50 > 0:17:53Quick, quick, quick! Quick, quick, quick!
0:17:53 > 0:17:56They're with five this time. He's got five.
0:17:56 > 0:17:58All of them! All of them! All of them! Come on!
0:17:58 > 0:18:01- Come on!- Remember, don't break any eggs, because they won't count.
0:18:01 > 0:18:03Don't drop any.
0:18:03 > 0:18:06And remember it's the first team to get all of their eggs.
0:18:06 > 0:18:09And the Yellows are doing very well.
0:18:09 > 0:18:10Done!
0:18:10 > 0:18:14Done! The Blues have done it, well done the Blue Team!
0:18:14 > 0:18:17Well done, come back to your places, please.
0:18:17 > 0:18:21So now I'm going to check because of course any broken ones won't count.
0:18:21 > 0:18:26Let's check them using my monkey nose. No, none there.
0:18:26 > 0:18:30No, that's pretty good. Wait a minute.
0:18:30 > 0:18:35Wait a minute! What's that?!
0:18:35 > 0:18:36A broken egg.
0:18:36 > 0:18:39It's a broken egg and I'm afraid that means it doesn't count.
0:18:39 > 0:18:43That means that the Yellow Team are the winners, well done, Yellows!
0:18:43 > 0:18:45Ten points to you.
0:18:45 > 0:18:48So The Yellow Experimenters successfully put all
0:18:48 > 0:18:53their eggs into one basket, moving them into the lead with 20 points!
0:18:53 > 0:18:57Light bulbs + brain = inspiration!
0:18:57 > 0:19:01It's time for our next round.
0:19:01 > 0:19:05- ECHOING:- Behold...
0:19:08 > 0:19:13..some cups. A tower of cups and a table of props.
0:19:13 > 0:19:15Cups, props, props, cups, cups, props, props cups, cups,
0:19:15 > 0:19:17cups, prop, prop, props.
0:19:17 > 0:19:21Now, teams, what you've got to do is devise a way to knock over
0:19:21 > 0:19:23this tower of cups.
0:19:23 > 0:19:24Looks pretty easy, doesn't it?
0:19:24 > 0:19:26They're flimsy, they're just made out of paper.
0:19:26 > 0:19:31And you have here a whole table full of props such as string, tape,
0:19:31 > 0:19:35more tape, an eggy thing, my mother's nose,
0:19:35 > 0:19:38a banana, scissors, cardboard,
0:19:38 > 0:19:40paper, everything. All sorts of things.
0:19:40 > 0:19:43Now, you've got to think of a way to knock over these cups
0:19:43 > 0:19:46and you have to remain behind this line.
0:19:46 > 0:19:50I'm going to give you now a few moments to think about your answers
0:19:50 > 0:19:52and then we're going to try them.
0:19:52 > 0:19:57Your thinking time starts now.
0:19:57 > 0:20:00THEY CONFER
0:20:00 > 0:20:03So, the teams have to come up with a plan to knock over
0:20:03 > 0:20:06as many cups as possible using the props available,
0:20:06 > 0:20:08like that one I'm sniffing there, very nice!
0:20:08 > 0:20:10And without crossing the line.
0:20:14 > 0:20:16PRETENDS TO PLAY FLUTE
0:20:16 > 0:20:20Time is up! Time to stop thinking and let's see your answers.
0:20:20 > 0:20:21Let's have a look.
0:20:21 > 0:20:23Ooh, some intriguing-looking things going on there.
0:20:23 > 0:20:27Very good. Well, let's start with the Yellow Experimenters.
0:20:27 > 0:20:35In this one the egg is covered with materials and the bike pump goes
0:20:35 > 0:20:38right through it and then the bananas go on the sides.
0:20:39 > 0:20:43Well, let's see if it works - come on down!
0:20:52 > 0:20:53This is real science at work.
0:20:58 > 0:21:03The Whoopsie-Daisy 800, built for one purpose. Teaching cups a lesson.
0:21:06 > 0:21:09I can see that Dr Imogen is holding it like this, so you're
0:21:09 > 0:21:12hoping that this is going to knock out the bottom row, is that right?
0:21:12 > 0:21:17- Yep.- Yeah.- Well, let's see if it works. In three, two, one, fire!
0:21:17 > 0:21:19Oh, unlucky!
0:21:19 > 0:21:22Oh, no. What a shame.
0:21:22 > 0:21:24Very, very unlucky.
0:21:24 > 0:21:28Didn't quite work, unfortunately.
0:21:28 > 0:21:30Let's see it again in slow motion, here she goes.
0:21:30 > 0:21:33Yeah, oh, look at me, I'm handsome, aren't I? What a handsome monkey.
0:21:33 > 0:21:35Lovely. Who's that?
0:21:35 > 0:21:40It was a nice, heavy implement that you slung with brutal force
0:21:40 > 0:21:42at the cups but, unfortunately,
0:21:42 > 0:21:45the aim was a little bit wrong which means no points, I'm afraid.
0:21:45 > 0:21:46But, good effort for trying.
0:21:46 > 0:21:48What a shame.
0:21:48 > 0:21:51Well done. Unlucky, there, the Yellows.
0:21:51 > 0:21:53OK, now, it's time for my friends 4 O'Clock Blues.
0:21:57 > 0:21:59# It's four o'clock and I've got the blues. #
0:21:59 > 0:22:01What's your plan? Let's see it.
0:22:02 > 0:22:04Three giant arrows.
0:22:04 > 0:22:08Which you're going to throw at a wedding cake. I like it.
0:22:08 > 0:22:10Explain, please, Dr Ruby.
0:22:10 > 0:22:14- Two bananas attached with string. - Yes, attached to...?
0:22:14 > 0:22:17- Attached with string. No, no, tape. - Together. Oh, with tape.- Yep.
0:22:17 > 0:22:21- And then we're just going to throw them at the cups.- I see.
0:22:21 > 0:22:24You're going to tie two bananas together and just throw them
0:22:24 > 0:22:25at the cups.
0:22:31 > 0:22:34Is there, by any chance, any sort of science involved in this?
0:22:34 > 0:22:36Or are you just thinking about just throwing bananas?
0:22:40 > 0:22:43The Banana Hawk 6,000.
0:22:43 > 0:22:47The mother of all banana-based cup-destroying...thingies..
0:22:49 > 0:22:51Ah, these are on a diagonal... Oh, my.
0:22:51 > 0:22:54Don't make it complicated, you're throwing bananas at cups.
0:22:54 > 0:22:55He's worried.
0:22:55 > 0:22:58Three! Two! One! Fire in the hole!
0:23:01 > 0:23:03Yes. That's all right, that's good, that's good.
0:23:03 > 0:23:06Not bad, not bad. That's not bad, there were a few cups remaining.
0:23:06 > 0:23:09Oh, here we see it again in slow motion.
0:23:09 > 0:23:13Flies across the screen, BANG, look at that. Oh, not quite, though.
0:23:13 > 0:23:15Not too bad. Now!
0:23:15 > 0:23:19Let's find out whether the Greens have a more elegant
0:23:19 > 0:23:21and scientific solution.
0:23:21 > 0:23:23So, Greens, let's see your plan.
0:23:23 > 0:23:27So, we got this banana, we're going to put cardboard around it and then
0:23:27 > 0:23:31tape that around and then we're just going to lob it at the cups.
0:23:31 > 0:23:37Oh, so once again deploying banana brutality at the cups
0:23:37 > 0:23:39in the hope that they're going to come tumbling down.
0:23:39 > 0:23:41Yes, that is what we're doing.
0:23:43 > 0:23:45Banana is there in the card.
0:23:49 > 0:23:50I'm so tense!
0:23:54 > 0:24:00Cup Over Mark 1. Precision engineered, paper, fruit and tape.
0:24:00 > 0:24:03Shock and awe. And fruit and tape. And paper.
0:24:03 > 0:24:05Are you confident?
0:24:06 > 0:24:08A little bit.
0:24:08 > 0:24:11Let's try it, then. Three! Two! One! Fire!
0:24:12 > 0:24:17- Yay!- Yes!- Yes!- Only one remaining, that is the best shot so far.
0:24:17 > 0:24:19- Are you pleased with that?- Yes.
0:24:27 > 0:24:29Yeah! Dancing, dancing!
0:24:29 > 0:24:30Victory dance!
0:24:31 > 0:24:33Victory dance!
0:24:33 > 0:24:38Let's see it in slow motion. Whoosh, and down it comes.
0:24:38 > 0:24:40And boom! Down it comes again. She got it twice.
0:24:40 > 0:24:44Ten points to the Greens. Put it there, good work.
0:24:48 > 0:24:54This is how Dr Brain, the monkey scientist, would do it.
0:24:54 > 0:24:56Now, you'll need an ordinary cardboard box,
0:24:56 > 0:25:00reinforce the edges with tape to make it as airtight as possible
0:25:00 > 0:25:02and cut a circular hole in one end -
0:25:02 > 0:25:04get an adult or science monkey to help you.
0:25:04 > 0:25:06For ultimate power, replace the cardboard at the back with
0:25:06 > 0:25:08a large square of latex material.
0:25:08 > 0:25:10If you can't find any, don't worry,
0:25:10 > 0:25:12just press the sides of the box to fire it instead.
0:25:12 > 0:25:15Now, pull back on the latex and fire!
0:25:19 > 0:25:21Now, because air is invisible,
0:25:21 > 0:25:23in order to help you see the movement, I've added some smoke!
0:25:23 > 0:25:26Look at that! Smoking!
0:25:26 > 0:25:30Boom! Down she comes. Who's that handsome devil?
0:25:30 > 0:25:36And so, as we enter the final round, the scores couldn't be any closer.
0:25:36 > 0:25:39It's getting so tense I think I'm going to cry.
0:25:39 > 0:25:43So now, all you have to do is answer questions on all subjects.
0:25:43 > 0:25:47You get two points per right answer. Are you ready?
0:25:47 > 0:25:49BLUE TEAM BUZZER
0:25:49 > 0:25:51- Yes.- Good. Hands on brains, please.
0:25:51 > 0:25:55Right, here we go. What does 1025 megabytes make?
0:25:55 > 0:25:58BLUE TEAM BUZZER
0:25:58 > 0:25:59A gigabyte.
0:25:59 > 0:26:00Is correct.
0:26:00 > 0:26:03Give me another name for a sphere beginning with B.
0:26:03 > 0:26:04YELLOW TEAM BUZZER
0:26:06 > 0:26:09- I didn't click it.- Yes, you did.
0:26:09 > 0:26:11Going to need an answer.
0:26:11 > 0:26:12BLUE TEAM BUZZER
0:26:12 > 0:26:15- A ball.- A ball is the right answer, yes, yes, yes.
0:26:15 > 0:26:17What's my uncle's name?
0:26:17 > 0:26:18YELLOW TEAM BUZZER
0:26:18 > 0:26:20- Bob. It's Bob.- Yes.
0:26:20 > 0:26:23How long does it take for light from the sun to reach the Earth?
0:26:23 > 0:26:25BLUE TEAM BUZZER
0:26:27 > 0:26:28Eight minutes.
0:26:28 > 0:26:31Is the right answer.
0:26:31 > 0:26:33What is the scientific name for water?
0:26:33 > 0:26:35YELLOW TEAM BUZZER
0:26:35 > 0:26:38- H20.- Aqua.- H20.- Aqua.
0:26:38 > 0:26:39H20. I will take that answer.
0:26:39 > 0:26:41- What?! She said aqua!- I said H20!
0:26:41 > 0:26:43What is 75 times 2?
0:26:43 > 0:26:45GREEN TEAM BUZZER
0:26:45 > 0:26:48- 150.- Is the right answer. They were the only ones listening.
0:26:48 > 0:26:50A 90-degree angle is also known as what kind of angle?
0:26:50 > 0:26:51YELLOW TEAM BUZZER
0:26:51 > 0:26:53- A right angle. - A right angle is the right answer.
0:26:53 > 0:26:55What animal is the word "canine" associated with?
0:26:55 > 0:26:57GREEN TEAM BUZZER
0:26:57 > 0:26:59- A dog.- A dog is the right answer.
0:26:59 > 0:27:02What is the word "spoons" backwards?
0:27:02 > 0:27:03GREEN TEAM BUZZER
0:27:03 > 0:27:07- Moops.- Say again?- Noops. - The answer is "snoops".
0:27:09 > 0:27:14That is the end of the round and that is the end of the game, folks.
0:27:14 > 0:27:19Let me tell you the results of the game. The winner is...
0:27:19 > 0:27:22- DRUM ROLL - With the title of Ultimate Brain...
0:27:22 > 0:27:23DRUM ROLL
0:27:23 > 0:27:26Thank you, thank you. Yes, yes, yes. Give it up. With 26 points,
