0:00:05 > 0:00:08What will happen when we mix up this multicoloured chemical cocktail?
0:00:09 > 0:00:12Can our teams stop GP slipping off her slippery pole?
0:00:14 > 0:00:18And will there be any smashing in this smashing experiment?
0:00:18 > 0:00:20Flex your thinking muscles,
0:00:20 > 0:00:24it's time for Ultimate Braaaaain!
0:00:29 > 0:00:32Ah-ha-ha-ha!
0:00:32 > 0:00:35My name is Dr Brain.
0:00:35 > 0:00:37If you like incredible action-packed experiments,
0:00:37 > 0:00:39scintillating science and more fun
0:00:39 > 0:00:41than a roller disco round the rings of Saturn
0:00:41 > 0:00:44then you're just the kind of genius I'm looking for.
0:00:47 > 0:00:48Electrifying!
0:00:48 > 0:00:51This is Ultimate Brain.
0:00:52 > 0:00:54Let's meet the teams.
0:00:54 > 0:00:57Here's three great brains in green from Newcastle, it's...
0:01:00 > 0:01:03From Hackney, in yellow and bright as sunbeams, it's...
0:01:08 > 0:01:11And our celebrity team from CBBC's Eve, it's...
0:01:16 > 0:01:18Our teams today are playing for the sheer honour of being victorious
0:01:18 > 0:01:21on the greatest science-based show known to man or monkey.
0:01:21 > 0:01:23Let's find out who they are.
0:01:23 > 0:01:26First we have the Greens! How are we doing, Greens?
0:01:26 > 0:01:28We're all right. Yeah.
0:01:28 > 0:01:30Oh, good, good, good, good. Now, are you big science fans?
0:01:30 > 0:01:33- Yeah.- What's your favourite thing in science?
0:01:33 > 0:01:35- Physics.- Physics.
0:01:35 > 0:01:36- Chemistry.- Chemistry.
0:01:36 > 0:01:38- Physics. - BUZZER
0:01:38 > 0:01:40Oh, I thought we were going to get a full set there.
0:01:40 > 0:01:42Lovely to meet you, what's your team name?
0:01:43 > 0:01:47Galactic Oblivion, good to meet you. It's the Greens!
0:01:47 > 0:01:49CHEERING
0:01:49 > 0:01:52- Yellows. How are you, Yellows? - Good.- Fine.
0:01:52 > 0:01:55Who's the best scientist out of the three of you, do you think?
0:01:55 > 0:01:58You? Now, what do you want to be when you get out of school?
0:01:58 > 0:02:01- A lawyer.- A lawyer?
0:02:01 > 0:02:05- Yeah.- Good at science, wants to be a lawyer. Nice one.
0:02:05 > 0:02:06Now, what's your team name?
0:02:07 > 0:02:09Braaaiin Boxes!
0:02:09 > 0:02:12Ladies and gentlemen, I present the Yellows!
0:02:12 > 0:02:13CHEERING
0:02:13 > 0:02:14It's the Blues.
0:02:14 > 0:02:19You are of course known to our friends from the wonderful show Eve.
0:02:19 > 0:02:22- Correct. - Any of you play a scientist?
0:02:22 > 0:02:24- That would be me.- That would be you. - Yeah.
0:02:24 > 0:02:27And of course you used your expert knowledge of science,
0:02:27 > 0:02:31to bring to the role, of course, being a brilliant scientist?
0:02:31 > 0:02:35- Yes - a GCSE B. - B? That's not too bad, actually.
0:02:35 > 0:02:37- Yes, well, are you looking forward to some good games?- Yes.
0:02:37 > 0:02:40- Do you think you're going to do well?- Yes.- I like that.
0:02:40 > 0:02:41What's your team name?
0:02:42 > 0:02:45Team Eve! It's good, it's simple, it's strong.
0:02:45 > 0:02:47Remember, teams, you will need to be at your most astonishingly
0:02:47 > 0:02:51awesome, brainy brilliant best to secure the points in this show.
0:02:51 > 0:02:55Ingenious ideas only, please. Yes, it's time for Ignition!
0:02:55 > 0:02:57CAR ENGINE REVS
0:03:01 > 0:03:04Lightning and thunder, it's started already.
0:03:04 > 0:03:07Yes, this brain ignition challenge is all about crazy, colourful
0:03:07 > 0:03:11chemical concoctions. Try saying that ten times quickly.
0:03:11 > 0:03:15So, here I have four liquids that you might find
0:03:15 > 0:03:17in an ordinary household.
0:03:17 > 0:03:22Golden syrup, vegetable oil, washing-up liquid,
0:03:22 > 0:03:24and methylated spirit,
0:03:24 > 0:03:27which is another word for paintbrush cleaner.
0:03:27 > 0:03:32Now, you must ask yourselves, "What will happen when I pour
0:03:32 > 0:03:35"all of these liquids into this large empty jar?"
0:03:35 > 0:03:38Ooh, what a question.
0:03:38 > 0:03:41Is this confusion I see on these fine faces?
0:03:41 > 0:03:42Nay, it cannot be.
0:03:42 > 0:03:45To make it simpler for you all, I'm going to give you four choices.
0:03:45 > 0:03:47Count them - four!
0:03:47 > 0:03:50Will they...
0:03:53 > 0:03:55HE MAKES BUBBLING SOUNDS
0:03:57 > 0:04:00..or D - Something else entirely
0:04:00 > 0:04:02of your own thinkety-thinking
0:04:02 > 0:04:05that even I haven't thunkedy-thunk. Ah-ha-ha!
0:04:05 > 0:04:08So, my crazy chemical cocktails conundrum crackers,
0:04:08 > 0:04:12time to decide amongst yourselves. Yes, your thinking time starts...
0:04:12 > 0:04:13now!
0:04:13 > 0:04:16- THEY WHISPER - Shh!
0:04:16 > 0:04:20So, four choices in the mix here but which one is correct?
0:04:20 > 0:04:23Think carefully about this cocktail, teams.
0:04:23 > 0:04:27Have you thought of your answer?
0:04:27 > 0:04:28..it won't glow...
0:04:28 > 0:04:30OK, OK, my terrific teams.
0:04:30 > 0:04:33All different levels of confidence I can see here.
0:04:33 > 0:04:37So, it's time to reveal your answers NOW!
0:04:37 > 0:04:38What have we got?
0:04:39 > 0:04:42We have a D and two Bs.
0:04:42 > 0:04:46Oh. Now, Blues, you've gone for D - something else...
0:04:46 > 0:04:49- Yes.- ..that you have thought of. What have you thunk of?
0:04:49 > 0:04:52- Eubha?- Well, what we think's going to happen is that
0:04:52 > 0:04:56the different substances are going to layer on top of each other.
0:04:56 > 0:04:58Oh, good thinking!
0:04:58 > 0:05:01This could be interesting. Well, let's see.
0:05:01 > 0:05:04Now then, Greens, let's go for your B. What have you thought?
0:05:04 > 0:05:06Well, we did trial and error, really.
0:05:06 > 0:05:09We thought it couldn't turn purple cos if it's paintbrush cleaner,
0:05:09 > 0:05:12you wouldn't want your paintbrush to turn purple.
0:05:12 > 0:05:13Ah, good thinking, good thinking.
0:05:13 > 0:05:15We didn't think it would be glow,
0:05:15 > 0:05:17- cos we weren't really sure what would make it glow.- Yes.
0:05:17 > 0:05:19We thought bubble vigorously because
0:05:19 > 0:05:22- there's a lot of different chemicals within it.- Ah, of course, yes.
0:05:22 > 0:05:25So there'd be a chemical reaction then? It's all going to bubble?
0:05:25 > 0:05:27Ooh, that could be fun, couldn't it?
0:05:27 > 0:05:30Now then, Yellows, so you've gone for the same thing - bubbling.
0:05:30 > 0:05:32Any reason why? What's your scientific logic there?
0:05:32 > 0:05:36Well, we know that washing-up liquid bubbles a lot...
0:05:36 > 0:05:38Yes, it does, doesn't it?
0:05:38 > 0:05:40..and with that much, we think that it will
0:05:40 > 0:05:45dominate all the other liquids and it will make it bubble.
0:05:45 > 0:05:47So, what's going to make the washing-up liquid dominate
0:05:47 > 0:05:51the other liquids then? Is it just a stronger chemical or...?
0:05:51 > 0:05:55- When I wash up...- He washes up. For one thing, let's get that.
0:05:55 > 0:05:57Good boy! You'd better start doing that.
0:05:57 > 0:05:59Yes, when you wash up...?
0:05:59 > 0:06:03Well, you only have to put a bit and the sponge bubbles a lot,
0:06:03 > 0:06:04- so with that much...- It's true.
0:06:04 > 0:06:08Oh, this is all very good scientific thinking here, folks. I like this.
0:06:08 > 0:06:12Well, you've all come to a cocktail of conclusions there, you see.
0:06:12 > 0:06:13HE LAUGHS
0:06:13 > 0:06:16But who has got this chemically correct?
0:06:16 > 0:06:17Shall we see what actually happens?
0:06:17 > 0:06:20- Yes.- Uh-huh.- Yes, I think we should, shouldn't we?
0:06:23 > 0:06:27If you feel like handling methylated spirits, don't.
0:06:27 > 0:06:30Please get a science teacher to help you, or a highly educated,
0:06:30 > 0:06:35terrifically talented and gorgeously handsome brainy scientist, like me.
0:06:35 > 0:06:38Let's try it, here we go. So, I'm going to begin now
0:06:38 > 0:06:41with our delicious, lovely golden syrup - very tasty.
0:06:43 > 0:06:45# La-di-da... #
0:06:45 > 0:06:48PFFRT.
0:06:48 > 0:06:52Oh, I do beg your pardon. Too much banana curry there.
0:06:52 > 0:06:55Right, let's pour on now the vegetable oil.
0:06:57 > 0:06:59Now the washing-up liquid.
0:06:59 > 0:07:02# Da-da-dee-da... #
0:07:04 > 0:07:08Nice and green, and then we'll finish with the methylated spirit.
0:07:08 > 0:07:10# La-da-dee-da-da... #
0:07:12 > 0:07:16In it goes there and let's see what has happened.
0:07:16 > 0:07:18Look at that, you see!
0:07:20 > 0:07:23So, even though we've used the same volume of each liquid,
0:07:23 > 0:07:26they all have different weights!
0:07:26 > 0:07:29The golden syrup is heaviest, or most dense, so sits at the bottom.
0:07:29 > 0:07:31The paintbrush cleaner
0:07:31 > 0:07:33is the lightest so sits on top.
0:07:33 > 0:07:34The other two are in between
0:07:34 > 0:07:36so they sit, well, in between.
0:07:36 > 0:07:38Stripy sciencey rainbow fun!
0:07:40 > 0:07:43There we have it! There's the answer - D,
0:07:43 > 0:07:45which means the Blues get ten points.
0:07:45 > 0:07:47Well done, you Blues!
0:07:54 > 0:07:58Now, my brainy boffins, this next challenge requires you
0:07:58 > 0:08:00to master a different mind-set.
0:08:00 > 0:08:03It's time to get creatively clever.
0:08:03 > 0:08:08Behold the Ultimate Brain slippery pole!
0:08:08 > 0:08:11Now, GP has been moonlighting as a secret agent
0:08:11 > 0:08:15and has only gone and got himself captured by the evil Dr Brainless.
0:08:15 > 0:08:16CAT MEOWS
0:08:16 > 0:08:20And as we can see here, he has very foolishly left
0:08:20 > 0:08:22an obvious way for GP to escape.
0:08:22 > 0:08:28A horizontal drain pipe leads to safety, but it's not that simple.
0:08:28 > 0:08:32This pole is covered in slippery slime. Ewww.
0:08:33 > 0:08:38So what genius gadgets have our three spy-tastic teams
0:08:38 > 0:08:40designed to help GP escape?
0:08:40 > 0:08:45Our teams were given two days, and a budget of £50
0:08:45 > 0:08:47to design their solution.
0:08:47 > 0:08:49Teams must think of a way
0:08:49 > 0:08:50to get GP from one side
0:08:50 > 0:08:52of the slimy pole to the other.
0:08:52 > 0:08:56Their designs need to consider balance and friction.
0:08:56 > 0:08:59Enough balance to keep GP on the pole and enough friction
0:08:59 > 0:09:02to give him some grip on its slimy surface
0:09:02 > 0:09:04so he doesn't fall off like this.
0:09:04 > 0:09:06Oh-ho!
0:09:06 > 0:09:08If any team gets GP to the other side,
0:09:08 > 0:09:12they win ten massive Honour Points.
0:09:12 > 0:09:16- And here he is! Drumroll, please. - DRUMROLL
0:09:16 > 0:09:18The spy who bugged me.
0:09:18 > 0:09:21- SEAN CONNERY ACCENT:- Straight from the quantum of scientific solace.
0:09:21 > 0:09:25He's no sky-fool - it's the undercover agent without fear.
0:09:25 > 0:09:27The name's Pig, Guinea Pig.
0:09:27 > 0:09:31- It's the Guinea Pig! - TRUMPETS FANFARE
0:09:31 > 0:09:35- TRUMPETS TAIL OFF - Right, where was I? Are you ready?
0:09:36 > 0:09:39Um, yeah, definitely. I'm ready...
0:09:39 > 0:09:40for lunch.
0:09:40 > 0:09:45No, it's not lunchtime, GP. You've go to escape from a spy prison
0:09:45 > 0:09:48to get across that slippery slimy drainpipe thing.
0:09:48 > 0:09:50Uh... Can I change my answer?
0:09:50 > 0:09:54No, sorry, I'm going to have to take, "Yes, I'm definitely ready."
0:09:54 > 0:09:56So let's see what our teams have come up with.
0:09:56 > 0:09:59First, it's the Greens!
0:09:59 > 0:10:03Guinea Pig, I think maybe you need to get a manicure, don't you?
0:10:03 > 0:10:04Indeed, I do.
0:10:04 > 0:10:07Either that or you're wearing some very weird gloves.
0:10:07 > 0:10:09What are they and why?
0:10:09 > 0:10:11Well, we chose gloves to help him move across
0:10:11 > 0:10:14because the suckers at the bottom, they'll help him stay on,
0:10:14 > 0:10:18- and the claws for grip. - And then what's up there?
0:10:18 > 0:10:22A skateboard for his body so A - he doesn't get covered in gunge,
0:10:22 > 0:10:24and B - it will make him go faster.
0:10:24 > 0:10:28So the skateboard I presume is going to work with
0:10:28 > 0:10:32the slipperiness of the pole and the suckers work against.
0:10:32 > 0:10:36- Yeah.- Ah, a two-pronged attack.
0:10:36 > 0:10:40Team Galactic Oblivion have gone for sucker-covered gloves
0:10:40 > 0:10:43with claws for grip, and a skateboard to help GP move along,
0:10:43 > 0:10:45and to look, like, really awesome.
0:10:45 > 0:10:48Suction cups work because there is less air on the inside
0:10:48 > 0:10:51than the outside. This allows the air on the outside to force
0:10:51 > 0:10:55the rubber against a smooth surface, sticking it firm.
0:10:55 > 0:10:58But won't the slime get in the way of the suction?
0:10:58 > 0:11:00Let's find out.
0:11:00 > 0:11:03- What's the name of it?- Skateclaws.
0:11:03 > 0:11:07Skateclaws! Ah, Santa's lesser-known brother.
0:11:07 > 0:11:10- So, are you ready?- Ready.
0:11:10 > 0:11:11Ready, Guinea Pig?
0:11:11 > 0:11:15- No!- Three, two, one, go!
0:11:15 > 0:11:17- Off he goes.- Sit near the middle of it...- Yes, instruct him.
0:11:17 > 0:11:20- ..cos then you're more balanced. - Oh, he's lost a fingernail.
0:11:20 > 0:11:23Oh, dear. Problem!
0:11:23 > 0:11:27Down he goes. That's a fail, isn't it?
0:11:27 > 0:11:29The slime made the pole hard to grip,
0:11:29 > 0:11:31even with their special sucker gloves
0:11:31 > 0:11:34and the smooth wheels of the skateboard just made it even harder
0:11:34 > 0:11:39for Guinea Pig to balance on the slimy pole. Gnarly, dude. Ow!
0:11:39 > 0:11:43Bad luck, no points there. Let's see the next plan.
0:11:43 > 0:11:48Now then, Yellows, is this how people dress up Hackney these days?
0:11:48 > 0:11:50- Well...- What's this all about?
0:11:50 > 0:11:53Our plan requires the bare strength from Guinea Pig
0:11:53 > 0:11:57and sandpaper to provide him friction so he can cross the pole.
0:11:57 > 0:11:59- Friction, yes.- So, the way he has to move across the pole
0:11:59 > 0:12:02is he has to have his two hands in front of him
0:12:02 > 0:12:05and in a baby motion try to pull himself.
0:12:05 > 0:12:09I see. So the sandpaper is going to cause friction and give him
0:12:09 > 0:12:12some grip on the pole, working against the slipperage of the pole.
0:12:12 > 0:12:15- Is that right?- Yes.- Yes.- Ah, good. Give us a twirl, Guinea Pig.
0:12:15 > 0:12:17WOLF WHISTLE
0:12:17 > 0:12:19The Brain Boxes have gone for friction-friendly
0:12:19 > 0:12:20sandpaper gloves and pads.
0:12:20 > 0:12:24They hope the rough surface of the sandpaper will allow Guinea Pig
0:12:24 > 0:12:28to get enough grip on the slimy pole and pull himself to victory.
0:12:28 > 0:12:30Get rough and ready, GP.
0:12:30 > 0:12:33Well, I think we should see if it works, don't you?
0:12:33 > 0:12:35- Yeah.- What's the name of your plan?
0:12:35 > 0:12:39- Sand-at-hand.- Sand-at-hand. Are you happy, Guinea Pig?
0:12:39 > 0:12:41I'm always happy, Dr Brain.
0:12:41 > 0:12:44Let's do this thang! Three, two, one, go!
0:12:44 > 0:12:48- Baby motion.- Yeah, baby motions. - Baby motion.
0:12:48 > 0:12:51- I literally can't move. - Oh, oh. Now...
0:12:51 > 0:12:54Use your legs and swing yourself. Yeah, good. Yeah, like that.
0:12:54 > 0:12:56- Come on.- Good, good.
0:12:56 > 0:12:59So, he has got some sort of grip on it then.
0:12:59 > 0:13:02Do you think that's the sandpaper or just...how he's...?
0:13:02 > 0:13:05Ohhh! There he goes!
0:13:05 > 0:13:09Down he goes! Ha-ha!
0:13:10 > 0:13:13GP certainly got to grips with things and made a good start,
0:13:13 > 0:13:15but as the slime built up on his sandpaper gloves,
0:13:15 > 0:13:17they just couldn't grip any more.
0:13:17 > 0:13:20Things went south pretty quickly, and so did GP.
0:13:20 > 0:13:23Unlucky there, Yellows. Let's see the next plan.
0:13:24 > 0:13:28Shoo, shoo! We don't allow animals... Oh, wait a minute.
0:13:28 > 0:13:31Oh, it's you, Guinea Pig. Ha-ha! There we go.
0:13:31 > 0:13:34Now, what on Earth is he wearing?
0:13:34 > 0:13:37- He's a sloth. - He's a sloth? And why is he a sloth?
0:13:37 > 0:13:42Basically, Doc, we've gone with a different tactic than everyone else.
0:13:42 > 0:13:45- Yes.- We've decided to go underneath it and hang on.
0:13:45 > 0:13:49- Ahhh!- And we decided, what animal does that?
0:13:49 > 0:13:53- Of course, a good old sloth.- They're quite lazy, essentially quite lazy...
0:13:53 > 0:13:57- Yes.- ..so to incentivise him, cos they like eating bugs...
0:13:57 > 0:13:59- To motivate him. - Of course, yes. Motivate.
0:13:59 > 0:14:01A little bug to make sure he keeps going to the end.
0:14:01 > 0:14:03Ah, very good.
0:14:03 > 0:14:07So, Team Eve have thrown science aside and put all their faith
0:14:07 > 0:14:10and their money in a fake fly for motivation,
0:14:10 > 0:14:12and a silly sloth costume.
0:14:12 > 0:14:16But could their zany thinking have some accidental science on its side?
0:14:16 > 0:14:20After all, there's a lot of fur to soak up the slippery slime.
0:14:20 > 0:14:23- What's the name of your plan? - The Reluctant Sloth.
0:14:23 > 0:14:25The Reluctant Sloth,
0:14:25 > 0:14:30read by Martin Jarvis tonight, 11.30 on BBC Radio Four.
0:14:30 > 0:14:35Here we go, Guinea Pig. In three, two, one, go, Guinea Pig!
0:14:35 > 0:14:40- Now he's started.- Go on, my son! - Move your legs.- Keep going!
0:14:40 > 0:14:42- Get the fly! Get the fly!- Come on!
0:14:42 > 0:14:45Oh, and look at that, the fur on the costume is
0:14:45 > 0:14:48so thick, it's soaking up most of the slime
0:14:48 > 0:14:51allowing GP to get a grip with his arms and his knees
0:14:51 > 0:14:53and keeping him nice and warm. Look at him go!
0:14:53 > 0:14:54He's off again!
0:14:54 > 0:14:59Here we go again and he's getting a little further than before.
0:14:59 > 0:15:01He could make it to the... Oh, no, he's so close!
0:15:01 > 0:15:04- Get back, get on... Up, up! - Get your legs up, Guinea Pig!
0:15:04 > 0:15:06- Put your effort into it. - Stomach muscles!
0:15:06 > 0:15:08Oh, so close!
0:15:08 > 0:15:10Still happy though.
0:15:10 > 0:15:13GP's slime-soaking fur was great for grip
0:15:13 > 0:15:16but the slime eventually built up, reducing the friction between
0:15:16 > 0:15:20the surfaces and leaving GP pulling hard, but going nowhere fast,
0:15:20 > 0:15:25and finally he went down with a sloppy slump.
0:15:25 > 0:15:29Well, unfortunately, nobody has made it to the end.
0:15:29 > 0:15:32That means nobody gets any points. Ah, what a shame.
0:15:32 > 0:15:34So let's see what that's done
0:15:34 > 0:15:35to the scores.
0:15:35 > 0:15:36Oh, look. A big fat nothing.
0:15:42 > 0:15:44This round is all about quick reactions.
0:15:44 > 0:15:47Our three teams are full of lightning-quick minds,
0:15:47 > 0:15:49but who will be the quickest to react to our challenge?
0:15:49 > 0:15:52Their finely-honed reflexes are so fast, it's too hard to judge,
0:15:52 > 0:15:54even for a super-brained monkey like me.
0:15:54 > 0:15:56So we're going to need a very special piece of equipment
0:15:56 > 0:15:58to help us decide a winner.
0:15:58 > 0:15:59It's time to bring out the
0:15:59 > 0:16:02- SLOWLY:- Slowmonizer,
0:16:02 > 0:16:07the supercool camera with super very slow motion,
0:16:07 > 0:16:09so that I can accurately see who has the quickest reactions,
0:16:09 > 0:16:11and will be taking all the points.
0:16:11 > 0:16:13Now, one nominated contestant from each team is standing
0:16:13 > 0:16:16here behind the balloon of their team colour,
0:16:16 > 0:16:18armed with an ultimate balloon-popping pin.
0:16:18 > 0:16:19On the random sound of Dr Brain...
0:16:19 > 0:16:20HE WOOFS
0:16:20 > 0:16:23..they will pierce their balloons with said pins.
0:16:23 > 0:16:25The first to pop will be the winner!
0:16:30 > 0:16:31Ready?
0:16:35 > 0:16:36Woof.
0:16:36 > 0:16:39- Oh.- I wasn't expecting that.
0:16:40 > 0:16:42Oh, bursting with action there,
0:16:42 > 0:16:45but they were all so popping fast, we can't tell who was first.
0:16:45 > 0:16:47Well, there's only one way to be sure.
0:16:47 > 0:16:50Activate the Slowmonizer.
0:16:50 > 0:16:52Well, let's have a look here.
0:16:52 > 0:16:55They're all about to burst but Dr Oliver moves first,
0:16:55 > 0:16:57then Dr Ailbhe, then Dr Cinira.
0:16:57 > 0:16:59Oh, look at that. They're all wet but there's only one winner.
0:16:59 > 0:17:02- It's Dr Oliver. - CHEERING
0:17:02 > 0:17:04Ah, it was you, Blue!
0:17:04 > 0:17:07Well, bless my bananas, that was a close thing.
0:17:07 > 0:17:10You all have excellent super-speedy reactions,
0:17:10 > 0:17:14but Blue was the first so ten points to you.
0:17:15 > 0:17:18Now, if my maths is right, ten plus ten should equal 20.
0:17:18 > 0:17:19Ah, yes, it does. Well done, me.
0:17:25 > 0:17:30Now, my trusty Guinea Pig works very hard for me,
0:17:30 > 0:17:33bringing me all the equipment I need for my many marvellous
0:17:33 > 0:17:37experiments, but you know what? It was taking him a bit too long
0:17:37 > 0:17:39going up and down the stairs all the time,
0:17:39 > 0:17:43so Guinea Pig said, "Why don't I drop everything out of the window?"
0:17:43 > 0:17:45Boom!
0:17:45 > 0:17:48But it would smash up all my test tubes.
0:17:48 > 0:17:51Can you, our mighty-minded contestants, come up with a plan
0:17:51 > 0:17:56to get the racks of fragile test tubes down to the ground carefully?
0:17:56 > 0:18:01Now, this includes making a bung of course, to bung up the test tubes
0:18:01 > 0:18:04at the top to stop the liquids from spilling out.
0:18:04 > 0:18:08Now, on the tables in front of you are a variety of materials,
0:18:08 > 0:18:10which could be used to protect the test tubes.
0:18:10 > 0:18:14The team that has the most unbroken test tubes
0:18:14 > 0:18:18with the most liquid in them at the end wins.
0:18:18 > 0:18:24OK, my teams of clever cookies, don't smash or land with a crash.
0:18:24 > 0:18:26Your time starts...
0:18:26 > 0:18:28now! Start building!
0:18:30 > 0:18:34Teams can attempt to make the test tubes fall more slowly by creating
0:18:34 > 0:18:37designs with lots of air resistance, which will catch the air
0:18:37 > 0:18:39on the way down, sort of like a parachute.
0:18:39 > 0:18:42The slower something falls, the less force it lands with, you see.
0:18:42 > 0:18:45OK, I've got this. You could possibly tie it to the test tube.
0:18:45 > 0:18:49Ooh. They could also add shock absorbers to cushion the test tubes
0:18:49 > 0:18:51when they hit the ground, you see.
0:18:51 > 0:18:54Or, to put it scientifically, slowly, softly - lessy smashy.
0:18:54 > 0:18:57- Bill?- Yeah?- Don't just stand there. - Time's up, teams.
0:18:57 > 0:19:00That's it, time's up. So, you all think you've come up
0:19:00 > 0:19:02with a great plan to make my rack of test tubes
0:19:02 > 0:19:05have a safe landing. I hope you have. Fabulous.
0:19:05 > 0:19:07But don't let my praise go to your clever heads.
0:19:07 > 0:19:11Let's test these ideas out. First, the Blues!
0:19:12 > 0:19:16Now then, either one of my goldfish has been to a jumble sale,
0:19:16 > 0:19:19or this is the Blue creation. What is it?
0:19:19 > 0:19:21- This is Poppy Parrot.- Poppy Parrot?
0:19:21 > 0:19:23Yes. She's a bit shy cos she's not been on telly before.
0:19:23 > 0:19:26- PARROT SQUAWKS - Aw! What's she made out of?
0:19:26 > 0:19:29- Cotton wool, balloon belly. - Oh, so there's a bit of
0:19:29 > 0:19:31- balloonage in there? - A bit of balloon.- Bubble wrap.
0:19:31 > 0:19:34- There's bubble wrap.- Yes, bubble wrap.- So, what you're doing there
0:19:34 > 0:19:36- is cushioning the blow of the impact.- Yes.
0:19:36 > 0:19:38- You've gone for cushioning. - Cushioning.- Yes.
0:19:38 > 0:19:41- So, shall we see if it works? - Why not?- Why not?
0:19:41 > 0:19:44Let's give it a go. Let's pop her up to the Guinea Pig.
0:19:48 > 0:19:50Are you ready, Guinea Pig?
0:19:50 > 0:19:52I was born ready, Dr Brain.
0:19:52 > 0:19:55Three, two, one, go!
0:19:55 > 0:19:57Come on, Poppy Parrot! Fly! Be free!
0:19:57 > 0:19:59Oh, there was quite a healthy sort of sound there.
0:19:59 > 0:20:02I didn't hear too much smash and tinkle.
0:20:02 > 0:20:05Let's see what the damage is.
0:20:05 > 0:20:10Dr Matilda, our laboratory expert is going to open up your package
0:20:10 > 0:20:13and see exactly how much damage has been done,
0:20:13 > 0:20:16and how much liquid has been saved inside the test tubes.
0:20:16 > 0:20:19Expert precision, she's going to use.
0:20:19 > 0:20:21We were quite generous with the Sellotape.
0:20:21 > 0:20:24Yes, yes, you've made it... It's quite tough, I think.
0:20:24 > 0:20:27- Yes.- There's the first two layers. - Perfectly preserved.
0:20:27 > 0:20:29- Perfectly preserved. - Oh, look at that.- Wow.
0:20:29 > 0:20:32Now let's have a look. There are the test tubes.
0:20:32 > 0:20:36Now, Dr Matilda, give us a thumbs up if you think they both look intact.
0:20:39 > 0:20:43We get the thumbs up from Dr Matilda, they're both intact!
0:20:43 > 0:20:46Now we need to see how much liquid is left inside.
0:20:46 > 0:20:49Let's have a look and see.
0:20:49 > 0:20:52Ah, lovely blue liquid, you see, cos they're the Blue Team.
0:20:52 > 0:20:54There we go!
0:20:54 > 0:20:56So, Team Eve went for maximum cushioning
0:20:56 > 0:20:58with super-soft cotton wool,
0:20:58 > 0:21:02impact-absorbing bubble wrap and a comfy cloth covering.
0:21:02 > 0:21:05No breakages and no spillages. Awesome, dude.
0:21:07 > 0:21:11Well thought through and well executed. A good plan by the Blues.
0:21:11 > 0:21:13Well done, you Blues!
0:21:13 > 0:21:15Let's see the next plan.
0:21:15 > 0:21:18They're from Hackney, they're the Yellows. What's the plan?
0:21:18 > 0:21:22We've thought about, not slowing down the landing,
0:21:22 > 0:21:24but the impact so...
0:21:24 > 0:21:27So, talk me through what materials you've used here.
0:21:27 > 0:21:29- Bubble wrap.- Bubble wrap.
0:21:29 > 0:21:30- Cotton wool.- Cotton wool.
0:21:30 > 0:21:35- String.- And you've got a couple of balloons on the top there.
0:21:35 > 0:21:38Before we put the balloons, we put some plastic over it just to seal it.
0:21:38 > 0:21:41So basically if any water goes into the balloons
0:21:41 > 0:21:43it will just go back into the tube.
0:21:43 > 0:21:45It'll go back into... You've thought this through.
0:21:45 > 0:21:47Very good, let's do it.
0:21:47 > 0:21:50Take it up to Guinea Pig and let's see it in action.
0:21:50 > 0:21:53Are you ready, Guinea Pig? Here we go.
0:21:53 > 0:21:55Three, two, one, go!
0:21:57 > 0:21:59- SMASHING - Oh!- Ahh!
0:21:59 > 0:22:01Ah, now, I heard a noise there.
0:22:01 > 0:22:03That's all water.
0:22:04 > 0:22:07We're going to have a look and see
0:22:07 > 0:22:12if anything at all has been saved, and what damage there is.
0:22:12 > 0:22:14Of course, she has special gloves on,
0:22:14 > 0:22:16so that if there is any broken glass...
0:22:16 > 0:22:19Ultimate Brain Warning - Caution.
0:22:19 > 0:22:22When picking up broken glass, always use safety gloves.
0:22:22 > 0:22:26Personally, I use a lab assistant, like Dr Matilda here.
0:22:26 > 0:22:30Oh, dear. They're both broken. Now what we have to do
0:22:30 > 0:22:33is see if any liquid is left inside them.
0:22:34 > 0:22:37It's just glass, oh...
0:22:37 > 0:22:41Ohhh, a barely noticeable amount.
0:22:41 > 0:22:44So, the Brain Boxes also went for cushioning with cotton wool
0:22:44 > 0:22:48and bubble wrap, but they left the hard frame of the test tube rack
0:22:48 > 0:22:51exposed and that channelled the force of the impact
0:22:51 > 0:22:53right through to the glass of their test tubes.
0:22:53 > 0:22:56Oh, smashing stuff, but not in a good way.
0:22:56 > 0:22:59Unlucky. Let's see the next plan!
0:23:00 > 0:23:02What's the plan?
0:23:02 > 0:23:05OK, so we've got the parachute to increase the air resistance.
0:23:05 > 0:23:09Oh, lovely and silky. Counteracting the gravity, you hope?
0:23:09 > 0:23:10Yes, and what else you got?
0:23:10 > 0:23:13And then we've got the cushion around it to lessen the impact
0:23:13 > 0:23:14- of the blow.- Yes.
0:23:14 > 0:23:17So we've got air resistance against the gravity,
0:23:17 > 0:23:18lessening the impact with cushioning.
0:23:18 > 0:23:21Lots of scientific plans in place here,
0:23:21 > 0:23:23all within one wonderful machine.
0:23:23 > 0:23:25Let's do it! Take it up to Guinea Pig
0:23:25 > 0:23:28and let's see it in flight.
0:23:28 > 0:23:29Exciting, isn't it?
0:23:31 > 0:23:34Three, two, one, go!
0:23:34 > 0:23:36DEVICE THUDS
0:23:36 > 0:23:40Well... Ha-ha-ha! Greens, come and join me.
0:23:42 > 0:23:45Now, the parachute didn't quite deploy, did it...?
0:23:45 > 0:23:48- No.- ..as successfully as one might have hoped.
0:23:48 > 0:23:51It did take a little bit of air though, didn't it?
0:23:51 > 0:23:55So it kind of... If it had a bit more distance,
0:23:55 > 0:23:58perhaps it might have worked. Now then...
0:23:59 > 0:24:03Ah, now, you've put some stuff inside the test tube, as well.
0:24:03 > 0:24:07Both of their test tubes look to me to be intact.
0:24:07 > 0:24:08CHEERING
0:24:08 > 0:24:13Now, look. Let's empty out the liquid. That's one.
0:24:13 > 0:24:16Now let's see the liquid from the other test tube.
0:24:16 > 0:24:18- Are you pleased so far?- Yeah.- Yeah.
0:24:18 > 0:24:22Let's see. Oh, that's a fair amount of liquid in there!
0:24:22 > 0:24:26Team Galactic Oblivion went for maximum cushioning materials
0:24:26 > 0:24:30AND air resistance with their silky green parachute.
0:24:30 > 0:24:31Look at that!
0:24:31 > 0:24:34And the cotton wool in the test tubes kept the liquid in
0:24:34 > 0:24:38and helped absorb the impact. Test tube-tastic, guys!
0:24:40 > 0:24:43So, that means both the Blues and the Greens have won
0:24:43 > 0:24:45and get ten points each!
0:24:45 > 0:24:48- Yes!- Whoo-hoo!- Yes!
0:24:48 > 0:24:50Team Eve have 30,
0:24:50 > 0:24:52the Brain Boxes have a massive,
0:24:52 > 0:24:53um, nothing,
0:24:53 > 0:24:56and Galactic Oblivion have ten.
0:24:56 > 0:24:57Ooh, there's catching up to do,
0:24:57 > 0:25:00that's for sure, but there's still honour to play for
0:25:00 > 0:25:02on Ultimate Brain.
0:25:07 > 0:25:12Nothing can prepare you for what could happen next on Ultimate Brain.
0:25:12 > 0:25:15Not even a three-month course at the institute of preparing you
0:25:15 > 0:25:17for what could happen next on Ultimate Brain.
0:25:17 > 0:25:20It really is quite a pointless course, that one.
0:25:20 > 0:25:22It's time for the quickfire round.
0:25:24 > 0:25:27Any of you mindfully magnificent teams could still win this.
0:25:27 > 0:25:30Hands on your desks! Remember, you get two points
0:25:30 > 0:25:31for each correct answer
0:25:31 > 0:25:35and you get nothing, zip, nada, goose eggs for a wrong answer,
0:25:35 > 0:25:37not even this half-eaten apple.
0:25:37 > 0:25:40Definitely not. This is mine, mine, all mine!
0:25:40 > 0:25:42Mwa-ha-ha!
0:25:42 > 0:25:43Oh, get off.
0:25:43 > 0:25:45Let's do this.
0:25:45 > 0:25:48The fear of which eight-legged beast is called arachnophobia?
0:25:48 > 0:25:50- Blue?- A spider.
0:25:50 > 0:25:51Is right!
0:25:51 > 0:25:53What sport was played on the moon's surface
0:25:53 > 0:25:55during the Apollo 14 mission?
0:25:55 > 0:25:56Green?
0:25:56 > 0:25:57Golf.
0:25:57 > 0:26:01- Correct!- What does the Bactrian camel famously have two of
0:26:01 > 0:26:03instead of just one?
0:26:03 > 0:26:04- Blue.- Humps.
0:26:04 > 0:26:08- Is right!- What are the two openings in your nose called?
0:26:08 > 0:26:09Blue?
0:26:09 > 0:26:11Nostrils.
0:26:11 > 0:26:12Correct.
0:26:12 > 0:26:16Name either of the two chemical elements that make up pure water.
0:26:16 > 0:26:17Green?
0:26:17 > 0:26:18Hydrogen and Oxygen.
0:26:18 > 0:26:19Very good.
0:26:19 > 0:26:24Which is the tallest building in the whole of the United Kingdom?
0:26:24 > 0:26:25Yellow?
0:26:25 > 0:26:26The Shard.
0:26:26 > 0:26:27Correct.
0:26:27 > 0:26:30The famous plumage of adult flamingo birds is usually which colour?
0:26:30 > 0:26:32- Blue?- Pink.
0:26:32 > 0:26:38- Yes.- In computing, what term is given to 1,000 megabytes?
0:26:38 > 0:26:40- Blue?- Gigabyte?
0:26:40 > 0:26:42- Correct.- Yes. - What shiny yellow precious metal...?
0:26:42 > 0:26:44- BELL RINGS - That's time!
0:26:44 > 0:26:47Quickedy quick, quickedy quick, quickedy, quickedy whoo.
0:26:47 > 0:26:50That was some furiously fast brain action there, folks.
0:26:50 > 0:26:53Every contestant gave it their bwainy, bwainy best.
0:26:53 > 0:26:56It's time for the results!
0:26:56 > 0:27:00It's all too much for me! We want to know, don't we? We want to know.
0:27:00 > 0:27:02Well, in third place, with two points...
0:27:02 > 0:27:03it's the Yellow Team!
0:27:03 > 0:27:05CHEERING
0:27:05 > 0:27:08In second place with 14 points...
