0:00:05 > 0:00:09What happens when a magnet takes a tumble down a tube?
0:00:09 > 0:00:13Can our teams invent a way to stop GP going off with a pop?
0:00:13 > 0:00:15And is this the worst sushi ever made?
0:00:16 > 0:00:19Flex your thinking muscles, it's time for...
0:00:26 > 0:00:29Ah! Ha-ha-oh-ha-ha!
0:00:29 > 0:00:32My name is Dr Brain.
0:00:32 > 0:00:34I am looking for fabulous thinkers,
0:00:34 > 0:00:36cunning conundrum crackers
0:00:36 > 0:00:39and levels of genius not previously seen on planet Earth.
0:00:40 > 0:00:42Oh! Oh-ho-ho-ho-ho.
0:00:42 > 0:00:44Sorry, I've got wind.
0:00:44 > 0:00:46Wind! Ha-ha-ha-ha!
0:00:46 > 0:00:50This is Ultimate Brain.
0:00:50 > 0:00:52Oh, sorry!
0:00:52 > 0:00:54It's time to meet the teams.
0:00:54 > 0:00:56They're super at science, they're from Salisbury,
0:00:56 > 0:00:57it's the Green Team...
0:00:59 > 0:01:01APPLAUSE
0:01:01 > 0:01:04They're from Nottingham and there's no stopping 'em,
0:01:04 > 0:01:05it's the Yellows...
0:01:09 > 0:01:12And our celebrity team, brilliant in blue from brilliant Blue Peter
0:01:12 > 0:01:14on CBBC, its...
0:01:19 > 0:01:21Our teams will be playing for...
0:01:21 > 0:01:23the glorious honour of victory.
0:01:23 > 0:01:25So let's meet the Greens.
0:01:25 > 0:01:26APPLAUSE
0:01:26 > 0:01:29How are you, Greens?
0:01:29 > 0:01:31- Now, do you like your science?- Yes.
0:01:31 > 0:01:33What's your favourite thing about science?
0:01:33 > 0:01:36- Explosions.- Explosions.- Explosions!
0:01:36 > 0:01:39Everybody loves explosions, don't they? Boom!
0:01:39 > 0:01:41Now, what's your team name?
0:01:43 > 0:01:47Oh-ho-ho-ho-ho! Good name. Nice to meet you, the Greens.
0:01:50 > 0:01:53Ah! Ha-ha-ha-ha-ha! Yellows, how are you?
0:01:53 > 0:01:56- Fine, thanks.- Good, thank you.- Do you like your science?- Yep.- We love it.
0:01:56 > 0:01:57- Are you up for a challenge?- Yeah.
0:01:57 > 0:01:59What's your team name?
0:02:01 > 0:02:02Marvellous!
0:02:02 > 0:02:05There they are, the Yellows.
0:02:05 > 0:02:07APPLAUSE
0:02:07 > 0:02:09Now, I don't need to make a Blue Team,
0:02:09 > 0:02:11because here's one I made earlier.
0:02:13 > 0:02:16- Because you are, of course, from... - ALL: Blue Peter.
0:02:16 > 0:02:18Fantastic, nice to meet you, Blues.
0:02:18 > 0:02:22Now, Dr Barney, what do you have in common, do you think, as presenters?
0:02:22 > 0:02:24Well, we all have a world record.
0:02:24 > 0:02:26Oh! What in particular do you have a record for?
0:02:26 > 0:02:29I was part of a team that gunged the most amount of people
0:02:29 > 0:02:31- in three minutes, which is pretty cool.- Oh-ho-ho!
0:02:31 > 0:02:34Fantastic! And, Radzi, your record?
0:02:34 > 0:02:37I'm the proud owner of the world record for the fastest time ever
0:02:37 > 0:02:39to get changed as Santa Claus.
0:02:39 > 0:02:40Now, then, Dr Lindsey, your record?
0:02:40 > 0:02:45So mine was the most people covered with shaving foam beards.
0:02:45 > 0:02:47Mess, mess, beards, beards...
0:02:47 > 0:02:50Yeah, there's a, sort of... There's a kind of link
0:02:50 > 0:02:51through all of these records.
0:02:51 > 0:02:54Well, it's fantastic to meet you all, are you up for a challenge?
0:02:54 > 0:02:57- Yes, we are, bring it on. - What's your team name?
0:02:57 > 0:02:58We are known as...
0:02:58 > 0:03:01The Golden Era, ah, I love it.
0:03:01 > 0:03:04Me old gran will like that, as well.
0:03:04 > 0:03:06Very nice, it's the Blues!
0:03:08 > 0:03:11Well, teams, you'll need to keep those keen minds focused
0:03:11 > 0:03:16for every millisecond to snaffle up the points on this show.
0:03:16 > 0:03:19Engage your brain ignitions!
0:03:27 > 0:03:31HE HUMS BLUE PETER THEME TUNE
0:03:31 > 0:03:33This is the Brain Ignition challenge.
0:03:33 > 0:03:35It's all magnetism,
0:03:35 > 0:03:38and I'm not just talking about my magnetic personality.
0:03:38 > 0:03:40Ha-ha-ha!
0:03:40 > 0:03:44So take this long aluminium tube, or as I like to call it,
0:03:44 > 0:03:46the Mouse Hole Express.
0:03:46 > 0:03:49I'm not mad, hang on in there, there is a point.
0:03:49 > 0:03:53Now, watch what happens when I take this little toy mouse,
0:03:53 > 0:03:56little Mick here, and I drop him down the tube. Are you ready?
0:03:56 > 0:03:59What's going to happen? Here he goes, off you go, Mick.
0:03:59 > 0:04:00"I don't want to do it."
0:04:00 > 0:04:03Just get on with it. "Aggrh!" Oomph! Off he goes.
0:04:03 > 0:04:09Now, look at this large magnet which I've chosen as so as not to scare
0:04:09 > 0:04:11poor little Mick down there.
0:04:11 > 0:04:13Now, my brainy bunch, what do you think will happen
0:04:13 > 0:04:17when I drop this magnet into the aluminium tube?
0:04:17 > 0:04:20Well, the answer's quite simple for a monkey brainbox like me.
0:04:20 > 0:04:24But to make it simpler for all of you, you have four choices.
0:04:24 > 0:04:25Captain, four!
0:04:25 > 0:04:31Will the magnet...?
0:04:39 > 0:04:43..that only your genius minds can fathom,
0:04:43 > 0:04:45that even I have not thought of.
0:04:45 > 0:04:48Hmmm, now, which answer are your marvellous minds
0:04:48 > 0:04:51magnetically attracted to?
0:04:51 > 0:04:52Time to decide amongst yourselves.
0:04:52 > 0:04:56Yes, your thinking time starts now!
0:04:56 > 0:04:58THEY CONFER
0:04:58 > 0:05:00So four magnetic micey choices here.
0:05:00 > 0:05:02Think carefully, teams.
0:05:02 > 0:05:04Have you thought of your answer?
0:05:04 > 0:05:06THEY CONFER
0:05:06 > 0:05:07ALARM BLARES
0:05:07 > 0:05:10OK, OK, everyone, that's your time up.
0:05:10 > 0:05:13Reveal your answers, please, now!
0:05:13 > 0:05:15What have we got?
0:05:18 > 0:05:21Oh, well, let's go with the odd one out first.
0:05:21 > 0:05:23Blue Peter, you've gone for D.
0:05:23 > 0:05:25OK, I've got to take responsibility
0:05:25 > 0:05:27- for this.- OK, I like that.
0:05:27 > 0:05:29I think it would depend upon which
0:05:29 > 0:05:32way you turn the magnet because
0:05:32 > 0:05:34that would affect the direction
0:05:34 > 0:05:36of the line of magnetic flux.
0:05:36 > 0:05:39So, I think it would either go slower
0:05:39 > 0:05:41or quicker depending upon
0:05:41 > 0:05:42which way you turn the magnet.
0:05:42 > 0:05:44So there isn't a single answer.
0:05:44 > 0:05:46Effectively what's happened there is they've gone,
0:05:46 > 0:05:48"Bzz! I don't know."
0:05:48 > 0:05:49Well, let's see about the Greens.
0:05:49 > 0:05:51Now, why C?
0:05:51 > 0:05:53Because we think that as it's going
0:05:53 > 0:05:55through the aluminium tube it
0:05:55 > 0:05:57won't... It's slightly larger so it
0:05:57 > 0:06:00won't exactly attach to the side
0:06:00 > 0:06:02because not all of it can attach on
0:06:02 > 0:06:05and maybe it will slowly go down.
0:06:05 > 0:06:07- Oh, so a sort of magnetic field created in there.- Yeah.
0:06:07 > 0:06:10Oh, I see, right, OK, very interesting.
0:06:10 > 0:06:12Now, Yellows, you've come up with the same answer,
0:06:12 > 0:06:13is it the same science that
0:06:13 > 0:06:15you're thinking of?
0:06:15 > 0:06:17We sort of agree with the fact
0:06:17 > 0:06:18that it's going slower because
0:06:18 > 0:06:21the magnetic force from all around
0:06:21 > 0:06:23is clinging to the tube,
0:06:23 > 0:06:25so it will go down like a cat falling
0:06:25 > 0:06:26down a wall and clawing on it.
0:06:26 > 0:06:29Shall I tell you a little secret about aluminium?
0:06:29 > 0:06:30It's not magnetic.
0:06:31 > 0:06:35So, but, OK, you've made your choices,
0:06:35 > 0:06:36your Cs and your Ds.
0:06:36 > 0:06:38Shall we observe what actually happens
0:06:38 > 0:06:40when we drop the magnet down the aluminium tube?
0:06:40 > 0:06:43- What do you think, shall we try it? - ALL: Yes!- Yes!
0:06:43 > 0:06:45Yas! Right, here we go.
0:06:45 > 0:06:48Getting into position now...
0:06:48 > 0:06:50There's the tube...
0:06:50 > 0:06:51There's the magnet...
0:06:54 > 0:06:55ALL: Whoa!
0:06:55 > 0:06:58Ah-ha-ha-ha! There, you see?!
0:06:58 > 0:07:03That is what we call on Ultimate Brain "a wow moment".
0:07:03 > 0:07:06The magnet falls slowly because it creates a marvellous magnetic field
0:07:06 > 0:07:08inside the metal of the pipe.
0:07:08 > 0:07:10This pushes the magnet in the opposite direction to gravity,
0:07:10 > 0:07:13putting the brakes on its fall to earth.
0:07:13 > 0:07:16Mouse-mungously magnetastic!
0:07:16 > 0:07:20So the magnetically magnificent answer is C,
0:07:20 > 0:07:23which means the Yellows and the Greens get 5 points each.
0:07:23 > 0:07:25Well done!
0:07:25 > 0:07:29And they're off! But don't worry, Blues, plenty of time to catch up.
0:07:34 > 0:07:38It's my 300th birthday next week.
0:07:38 > 0:07:40# Happy Birthday... #
0:07:40 > 0:07:44I know, I don't look a day over 299.
0:07:44 > 0:07:48And the good old Ultimate Brain balloon inflators
0:07:48 > 0:07:50have been puffing away all week,
0:07:50 > 0:07:53blowing up lovely balloons for my mega monkey party.
0:07:53 > 0:07:58Now, they've stored them in this massive balloon storage pit,
0:07:58 > 0:08:02which has given me a scientifically pop-tastic idea.
0:08:02 > 0:08:05Hmmm... How can one travel from one side of the tank
0:08:05 > 0:08:08to the other popping the least amount of my balloons?
0:08:08 > 0:08:13Sound easy? Not if you can't touch the floor, it ain't.
0:08:13 > 0:08:15- Teams, did you rise to the challenge?- ALL: YEAH!
0:08:15 > 0:08:17Of course they did!
0:08:17 > 0:08:19The teams were given two days
0:08:19 > 0:08:21and a budget of £50 to design
0:08:21 > 0:08:24their solutions to the challenge.
0:08:24 > 0:08:28Our teams need to think about balance and weight distribution.
0:08:28 > 0:08:31Spreading the force of GP's weight to help GP cross the tank
0:08:31 > 0:08:34without bursting my balloons,
0:08:34 > 0:08:37or a device that keeps him off the ground but still allows him
0:08:37 > 0:08:38to move along.
0:08:38 > 0:08:41If GP's feet touch the bottom an alarm will sound - awooga! -
0:08:41 > 0:08:44and their attempt will be over.
0:08:44 > 0:08:46The winning team is the one that gets GP across the tank
0:08:46 > 0:08:49with the least balloons popped.
0:08:49 > 0:08:53So let's meet the most dedicated balloon blower-upper
0:08:53 > 0:08:56in the known universe, it's the unstoppable,
0:08:56 > 0:08:58it's the unpoppable
0:08:58 > 0:09:01Guinea Pig!
0:09:04 > 0:09:06Oh-ha-ha-ha-ha! Look at him!
0:09:06 > 0:09:07Oh-ho-ho!
0:09:07 > 0:09:09# Balloons! #
0:09:09 > 0:09:11He's trying to launch his pop career, do you get it?
0:09:11 > 0:09:14Pop because of balloons, you see?
0:09:14 > 0:09:16Oh, just stick to the things you're good at like falling over
0:09:16 > 0:09:19and counting sheep in your sleep. Ha-ha-ha-ha-ha!
0:09:19 > 0:09:21So let's see what the teams have come up with.
0:09:21 > 0:09:23First up, it's the Yellow Team, come on!
0:09:23 > 0:09:25Go on, Yellows!
0:09:25 > 0:09:28Now, I can't help thinking that Guinea Pig
0:09:28 > 0:09:30looks like he's about to go windsurfing
0:09:30 > 0:09:32whilst sweeping the floor.
0:09:32 > 0:09:34What's that all about?
0:09:34 > 0:09:38Well, he'll use the two brooms to push himself forwards
0:09:38 > 0:09:40without popping the balloons.
0:09:40 > 0:09:44The V shape of the cardboard in the front will push the balloons
0:09:44 > 0:09:46- out of the way, so he doesn't run them over.- Oh, right.
0:09:46 > 0:09:51And, just in case, we've got fans on either side just to blow them away.
0:09:51 > 0:09:54The Atomic Atoms have gone for a trolley system
0:09:54 > 0:09:59to keep GP's feet off the floor, with brooms to propel himself along.
0:09:59 > 0:10:02They hope their fan-assisted V-shaped shield will plough
0:10:02 > 0:10:05through the balloons whilst gently blowing them aside,
0:10:05 > 0:10:08giving the minimal poppage and maximum pointage.
0:10:08 > 0:10:11Tell me the name of your plan.
0:10:11 > 0:10:13- The Trolley Train.- The Trolley Train!
0:10:13 > 0:10:17- I like it. So are you ready? - ALL: YES.- Yes, let's do it.
0:10:17 > 0:10:22Three, two, one, your minute starts now, Guinea Pig!
0:10:22 > 0:10:24- Push!- Turn them around! - Turn them around!
0:10:24 > 0:10:27- Come on, you can do it!- Come on!
0:10:27 > 0:10:28Keep going, keep going, keep going!
0:10:28 > 0:10:30Come on, push as hard as you can!
0:10:30 > 0:10:32Oh, a sea of tranquillity...
0:10:32 > 0:10:34BALLOON POPS
0:10:34 > 0:10:36Well, it was. Oh!
0:10:36 > 0:10:39Only a few, though, that's all right. He's got all those...
0:10:39 > 0:10:42Just keep going, ignore them!
0:10:42 > 0:10:44If you want, use the ends of the brooms
0:10:44 > 0:10:46to brush the balloons behind you.
0:10:46 > 0:10:48Yeah, push them out the way!
0:10:48 > 0:10:51Ah, there, you see? He's lost the end of one.
0:10:51 > 0:10:53You're nearly there.
0:10:53 > 0:10:54- Come on!- Go, go!
0:10:54 > 0:10:56And that's time!
0:10:56 > 0:11:00That's time, that's time.
0:11:00 > 0:11:02Well, almost made it.
0:11:02 > 0:11:06The Atomic Atom's fantastic plough device worked well,
0:11:06 > 0:11:08allowing them to burst very few balloons,
0:11:08 > 0:11:11but their brooms just didn't provide GP with enough grip
0:11:11 > 0:11:15on the floor to move fast enough. But will they sweep up the points?
0:11:15 > 0:11:17He didn't do too badly,
0:11:17 > 0:11:19he got about three-quarters of the way across, I think,
0:11:19 > 0:11:20didn't he, there?
0:11:20 > 0:11:24- And he only popped four balloons, so that's pretty good.- That's not bad.
0:11:24 > 0:11:26But will it be good enough? We'll find out.
0:11:26 > 0:11:29Next, it's the Greens.
0:11:29 > 0:11:32Now, my friend Mr Guinea Pig is...
0:11:32 > 0:11:33Oh, my bananas!
0:11:33 > 0:11:35Guinea Pig, what's happened to your legs?
0:11:35 > 0:11:37SCREAMS
0:11:37 > 0:11:40- What have you done with his legs?! - What have you done to my legs?!
0:11:40 > 0:11:43- Ah-ho-ho-ho-ho! - He's kneeling down.
0:11:43 > 0:11:45- Oh!- Oh, there they are.
0:11:45 > 0:11:47Thank bananas for that.
0:11:47 > 0:11:49So why is he kneeling down, and what's he kneeling on?
0:11:49 > 0:11:53So he's on a little sled thing attached to wheels
0:11:53 > 0:11:58and using the shoe, he'll get grip on the bottom and push his way across.
0:11:58 > 0:12:00Then he's got a rope around him,
0:12:00 > 0:12:03so if he's going to fall he can hold on to that.
0:12:03 > 0:12:06Oh, I see, yes, because he mustn't touch the floor, must he?
0:12:06 > 0:12:08The Terrific Tree Trio
0:12:08 > 0:12:11have gone for a really good sled with a shoe paddle
0:12:11 > 0:12:14to give GP grip on the floor. A rope will hopefully help keep
0:12:14 > 0:12:17GP stable and sturdy as he moves along.
0:12:17 > 0:12:20Don't drop, don't pop, whatever you do, don't stop, that's the plan!
0:12:20 > 0:12:22What's your plan name?
0:12:22 > 0:12:24ALL: The Shoe Sled.
0:12:24 > 0:12:27- Greens, are you ready?- ALL: Yes.
0:12:27 > 0:12:31- Guinea Pig, are you ready? - I'm ready, Dr Brain.
0:12:31 > 0:12:35Fantastic, your time starts three, two, one, now!
0:12:35 > 0:12:38Push really hard, Guinea Pig!
0:12:38 > 0:12:39That's it, yes, tell him, tell him.
0:12:39 > 0:12:41- Up the other side! - Use it like a canoe.
0:12:43 > 0:12:47- Come on, Guinea Pig, keep going! - Come on, you can do it!
0:12:47 > 0:12:50It sort of looks like he's kayaking or something, doesn't it?
0:12:50 > 0:12:52- You're almost there, come on, keep going...- He's nearly there!
0:12:52 > 0:12:55- ..as fast as you can.- Come on!
0:12:55 > 0:12:57Is he there? Have you done it, Guinea Pig?
0:12:57 > 0:12:59- He's there!- ALL: Yeah!
0:12:59 > 0:13:02- He's done it.- Zero balloons.
0:13:02 > 0:13:05Wow, in the nick of time! They had trouble steering at the start
0:13:05 > 0:13:08but the Terrific Tree Trio's top canoeing tips
0:13:08 > 0:13:10and the grippy shoe on his paddle allowed GP to
0:13:10 > 0:13:12weally, weally wield his way to the finish
0:13:12 > 0:13:14without popping a single balloon.
0:13:14 > 0:13:16Beat that, Blues.
0:13:16 > 0:13:19You did something clever for once, Guinea Pig!
0:13:19 > 0:13:23- Well done, how do you feel? - I feel very brainy, Dr Brain.
0:13:23 > 0:13:26Oh-ho-ho! Good boy! Well, there you go, Greens.
0:13:26 > 0:13:28Is it going to be enough to win the challenge?
0:13:28 > 0:13:32I guess we'll only find out when we see the Blue plan.
0:13:32 > 0:13:34So, here we are with the Blues.
0:13:34 > 0:13:37Now, you've got a rather special plan, I understand.
0:13:37 > 0:13:41- It involves a bit of a dramatic reveal.- It's a style thing.
0:13:41 > 0:13:44Oh-ho-ho-ho! Well, would you like to introduce my friend, the guinea pig?
0:13:44 > 0:13:47Yeah, shall we do it? Ladies and gentlemen, boys and girls,
0:13:47 > 0:13:50please welcome the glamorous, the beautiful Guinea Pig.
0:13:50 > 0:13:52APPLAUSE AND LAUGHTER
0:13:54 > 0:13:55- Oh-ho-ho-ho!- Yes!
0:13:55 > 0:13:57WOLF WHISTLES
0:13:57 > 0:13:59Guinea Pig!
0:13:59 > 0:14:03You look sort of lovely in a kind of very strange sort of way.
0:14:03 > 0:14:05Now, what is this all about?
0:14:05 > 0:14:07There is a method behind the madness.
0:14:07 > 0:14:11So with the large creation we have, that will simply
0:14:11 > 0:14:13push the balloons away, and like Sir Ranulph Fiennes,
0:14:13 > 0:14:16the tennis rackets will mean you simply walk over the balloons,
0:14:16 > 0:14:19- it doesn't even matter if you stand on them.- Oh, I see.
0:14:19 > 0:14:22The Golden Era have gone for style AND science.
0:14:22 > 0:14:25They hope GP's beautiful ball gown will create an elegant,
0:14:25 > 0:14:28soft, balloon-friendly shield around him,
0:14:28 > 0:14:31allowing him to glide through without popping.
0:14:31 > 0:14:34Tennis racket shoes are designed to keep GP off the floor
0:14:34 > 0:14:36and distribute his weight in case he steps on a balloon.
0:14:36 > 0:14:40It's ballooning beautiful, but is it brilliant?
0:14:40 > 0:14:42Let's find out the name of your plan.
0:14:42 > 0:14:45It's called "Balloon Peter".
0:14:45 > 0:14:48Balloon Peter! I love it.
0:14:48 > 0:14:51- Are you confident? - Oh, yeah, we've won this.- Ha-ha!
0:14:51 > 0:14:54- Shall we see it then?- Yes! - Ready, Guinea Pig?
0:14:54 > 0:14:56I'm feeling gorgeous, Dr Brain.
0:14:56 > 0:15:00Well, you're not looking gorgeous. So three, two, one, go!
0:15:00 > 0:15:02- Shuffle, shuffle!- There you go!
0:15:02 > 0:15:04That's it, just a nice little shuffle.
0:15:04 > 0:15:07- Wait, slowly, slowly, slowly! - ALL: Oh, no!- Slow down, slow down!
0:15:07 > 0:15:09- Think pageant contest.- Lunge, lunge.
0:15:09 > 0:15:11Technically, he's not touching the floor
0:15:11 > 0:15:14- because of the tennis shoes, you see?- Adoring crowds.
0:15:14 > 0:15:15How's our time, what's our time?
0:15:15 > 0:15:18- How do we know...?- We've got loads of time.- GP, GP, GP, GP!
0:15:18 > 0:15:20- He's getting there, he's getting there.- Touches the side,
0:15:20 > 0:15:22reaches out, puts his arm out, touches the side
0:15:22 > 0:15:25before he gets there. BALLOON POPS
0:15:25 > 0:15:27- ALL: Oh, no!- There goes another. - Easy!
0:15:27 > 0:15:31- That was after.- That doesn't count, that was after the whistle.
0:15:31 > 0:15:34Oh, fabulous, elegant and efficient.
0:15:34 > 0:15:36Their cushioning skirt was gentle on the balloons
0:15:36 > 0:15:37and the tennis racket shoes
0:15:37 > 0:15:40helped him stay perfectly balanced all the way across.
0:15:40 > 0:15:44They only burst two balloons and finished in plenty of time -
0:15:44 > 0:15:46gorgeous!
0:15:46 > 0:15:48It did get all the way to the end
0:15:48 > 0:15:51- but I'm afraid you popped two balloons...- Yeah.
0:15:51 > 0:15:53..and only one team made it all the way to the end
0:15:53 > 0:15:56without popping any balloons and that was the Greens!
0:15:56 > 0:15:57APPLAUSE
0:15:57 > 0:15:59So 10 points there for the Greens.
0:16:09 > 0:16:11We're going to need a very special piece
0:16:11 > 0:16:14of super cool scientific equipment for the next round.
0:16:14 > 0:16:16A laser bazooka?
0:16:16 > 0:16:19No, it's time to bring out the...
0:16:19 > 0:16:24This super cool camera records in very super-slow-motion
0:16:24 > 0:16:27so that I can accurately see who the winner is.
0:16:27 > 0:16:30Now, it's time to get grabby, and I ain't talking about
0:16:30 > 0:16:32goosing your grannies' bum...
0:16:32 > 0:16:33No, it's on the back of your hand,
0:16:33 > 0:16:37mate, it's a cup full of Ultimate Brain water.
0:16:37 > 0:16:40One person from each team will balance a cup
0:16:40 > 0:16:43on the back of their hands. On the random sound of Dr Brain -
0:16:43 > 0:16:46Oi! - you will pull your hand from beneath your cups
0:16:46 > 0:16:52and grab the cup before it tumbles down, with the same hand!
0:16:52 > 0:16:56The first person to successfully grab the cup is the winner.
0:16:56 > 0:16:58OK, here we go.
0:17:05 > 0:17:07Ready...
0:17:09 > 0:17:11..Oi!
0:17:11 > 0:17:12Oh, no!
0:17:12 > 0:17:14Oh! Off they drop.
0:17:14 > 0:17:17Three cups are up for grabs here, but who got a hand to theirs first?
0:17:17 > 0:17:20It's impossible to tell.
0:17:20 > 0:17:22Well, there's only one way to find out.
0:17:22 > 0:17:27Don't ask me, ask the slowmonizer.
0:17:27 > 0:17:29So, here we go, then, they're at the start...
0:17:29 > 0:17:32Oh, look, Dr Liam is off but, oh, he's used two hands, he's out.
0:17:32 > 0:17:34Here we go, it's Dr Emad and Dr Lindsey.
0:17:34 > 0:17:38Oh, Dr Emad's dropped his! Dr Lindsey is the winner!
0:17:38 > 0:17:41Blue there is the only one who managed to catch it
0:17:41 > 0:17:45with one hand, well done, it's 10 points to the Blues.
0:17:45 > 0:17:47Oh, that's going to change things around a bit.
0:17:47 > 0:17:50The Blues have moved from the bottom to the middle.
0:17:50 > 0:17:51Can they get to the top?
0:17:56 > 0:17:58# Yo, my brain need brethren
0:17:58 > 0:18:03# This inspiration challenge is All about rice, rice, baby. #
0:18:03 > 0:18:07Now, I like my cooking to be like my experiments - precise.
0:18:07 > 0:18:10So in these jars I have measured precisely how much rice I need
0:18:10 > 0:18:14for a super-sizzling chilli I'm going to make.
0:18:14 > 0:18:15Ho-ho-ho-ho!
0:18:15 > 0:18:18But one of me lovely, lovely juicy tomatoes has
0:18:18 > 0:18:21gone and got stuck at the bottom of the jar, you see? Bish, bash, bosh.
0:18:21 > 0:18:23But you can't use your hands, no,
0:18:23 > 0:18:27but you can use up to two of the objects and implements
0:18:27 > 0:18:33so beautifully arranged there to retrieve the tasty tom.
0:18:33 > 0:18:38Either that, or another scientastic idea, the choice is yours.
0:18:38 > 0:18:41But you cannot spill a grain,
0:18:41 > 0:18:44not a single grain, I tell you!
0:18:44 > 0:18:48Any spillages will result in disqualification.
0:18:49 > 0:18:51And, to prevent any Ultimate peeking
0:18:51 > 0:18:55and to make sure there is no Ultimate sneaking
0:18:55 > 0:18:57the two teams not doing the challenge
0:18:57 > 0:19:01will wear eye distracters and special earmufflers
0:19:01 > 0:19:04so that they can't plunder any science testing ideas.
0:19:04 > 0:19:08OK, teams, you have three minutes to design your methods, starting now.
0:19:08 > 0:19:10ALARM BLARES
0:19:10 > 0:19:12Our teams need to think about which item will allow them
0:19:12 > 0:19:16to use precise, steady movements for the tomato extraction.
0:19:16 > 0:19:18THEY CONFER
0:19:18 > 0:19:21Either that or another super secret sciencey method -
0:19:21 > 0:19:22mwa-ha-ha-ha!
0:19:22 > 0:19:24THEY CONFER
0:19:24 > 0:19:27All the rice you see here naturally grows in these wonderful colours.
0:19:27 > 0:19:29Of course, there's not a grain of truth in that.
0:19:29 > 0:19:32Did you get it?! A grain, you see?! Ha-ha! Oh, forget it!
0:19:32 > 0:19:35THEY CONFER ALARM BLARES
0:19:35 > 0:19:38Time's up, teams! That's it, no more thinking, no more designing,
0:19:38 > 0:19:41what have your brains got in store for my grains?
0:19:41 > 0:19:44Ha-ha! First up, it's the Greens.
0:19:44 > 0:19:47Talk me through the plan, Greens.
0:19:47 > 0:19:50Try and prod the tomato and hold it in place with the chopstick
0:19:50 > 0:19:53- and then using the spoon/fork thing...- Yes.
0:19:53 > 0:19:56..we're going to scoop it and hold it in place
0:19:56 > 0:19:58with the chopstick as we bring it up.
0:19:58 > 0:20:02Once it's done, we'll use the chopstick to pull the tomato up
0:20:02 > 0:20:05and pour out any of the rice in the spoon.
0:20:05 > 0:20:08Make sure when you pour it out it goes back in there,
0:20:08 > 0:20:11because if it goes on there, it's game over. Aah!
0:20:11 > 0:20:14So at the moment Little Tommy Tomato
0:20:14 > 0:20:18is here having a little rest at the bottom there, you see?
0:20:18 > 0:20:21But we want him to come and join us and play, join in the fun.
0:20:21 > 0:20:24So do you think you could rescue him?
0:20:24 > 0:20:25- ALL: Yes.- Let's see it in action.
0:20:25 > 0:20:27Off you go, your time starts now.
0:20:27 > 0:20:29ALARM BLARES
0:20:31 > 0:20:33Chopstick...
0:20:33 > 0:20:35Use the chopstick...
0:20:35 > 0:20:37- You see...?- Wow.
0:20:37 > 0:20:40It's actually quite difficult to get it through
0:20:40 > 0:20:43all the rice there, isn't it?
0:20:43 > 0:20:46It's actually harder than it looks, you know.
0:20:46 > 0:20:47I think I've stabbed the tomato.
0:20:47 > 0:20:51- I see.- Yeah, I can't...- Keep going.
0:20:51 > 0:20:53- Nearly spilt... - Do you need some help?- Yeah.
0:20:53 > 0:20:5530 seconds left now.
0:20:55 > 0:20:56ALARM BLARES
0:20:56 > 0:21:00Ah, I'm afraid that is "meh-ma!"
0:21:00 > 0:21:03Unlucky, Greens. Well, what a shame.
0:21:03 > 0:21:06Oh, the Terrific Tree Trio just couldn't shift
0:21:06 > 0:21:09the densely packed rice away to get to the tomato.
0:21:09 > 0:21:12The chopstick was too thin and the spoon was too fat.
0:21:12 > 0:21:15Grain over, game over, brain over!
0:21:15 > 0:21:18So now it's the turn of the Blue Team.
0:21:18 > 0:21:21Now, what have you chosen?
0:21:21 > 0:21:24Well, we've gone for the coat hanger and the spork,
0:21:24 > 0:21:25- it's a fork and a spoon, the spork. - Yes.
0:21:25 > 0:21:28But actually, we don't think we're really going to need anything.
0:21:28 > 0:21:32If our plan goes well, then we shouldn't need any equipment.
0:21:32 > 0:21:33Yes, because, of course,
0:21:33 > 0:21:36if you were listening very carefully at my briefing...
0:21:38 > 0:21:43Either that or another scientastic idea, the choice is yours.
0:21:43 > 0:21:48You know what I'm talking about. So shall we see your plan in action?
0:21:48 > 0:21:51- ALL: Yes.- Your time starts now. - Shake, shake, shake.
0:21:51 > 0:21:54So we're not sure if this is going to scientifically work
0:21:54 > 0:21:57but there must be something in the old shake. Oh, go on, go on, Barney.
0:21:57 > 0:22:00- Yes!- There you go, there you go.- Yes, yes, yes. Go on!- How will we know?
0:22:00 > 0:22:03I'll look under. Maybe do a bit of a shake that way too.
0:22:03 > 0:22:06- No, it's on top again! How about that way?- Oh, the other way round.
0:22:06 > 0:22:09- Yes, go on.- Oh, really?
0:22:09 > 0:22:12It's at the bottom, OK, this isn't working. Oh, no, no, no!
0:22:12 > 0:22:16- That way, that way, that way! - Go, go.- How is this not working?
0:22:16 > 0:22:18- It's a genius plan.- Dr Brain!
0:22:18 > 0:22:20I'm not saying a thing.
0:22:20 > 0:22:23- Shall we go for plan B? We haven't got long left.- Plan B, plan B.
0:22:23 > 0:22:26- I don't know how long we've got.- Was it that?- No, lengthways, like that.
0:22:26 > 0:22:28Stretch it out as far as you can. Like that, then go in like that.
0:22:28 > 0:22:30- Go!- Stir it.
0:22:30 > 0:22:31I'll hold it still. Come on, Barney.
0:22:31 > 0:22:33This isn't going to work either.
0:22:33 > 0:22:36- ALARM BLARES - Oh!- Oh, no!- That doesn't count.
0:22:36 > 0:22:39- No, look!- I'm afraid you spilt a bit of the rice there.
0:22:39 > 0:22:41That means it's game over, you've failed.
0:22:41 > 0:22:44Team Golden Era almost discovered our secret sciencey method,
0:22:44 > 0:22:46but they didn't.
0:22:46 > 0:22:49Their rice shaking was almost effective, but it wasn't.
0:22:49 > 0:22:52Let's just say they got the right idea but up the wrong way.
0:22:52 > 0:22:55Let's see how the Yellows do.
0:22:55 > 0:22:58What have you chosen, and what's your plan?
0:22:58 > 0:23:01- Well, we've chosen the plate.- Yes. - And a spatula.- Mm-hmm.
0:23:01 > 0:23:04And what we're going to do is, using the spatula we're going to try
0:23:04 > 0:23:07- and make a hole through it...- Yeah. - Like, a really fine hole.
0:23:07 > 0:23:09- A really tight hole.- We're going to put the plate on,
0:23:09 > 0:23:12put the spatula through and try to almost, like, pick it up.
0:23:12 > 0:23:15So it would get stuck between the plate and the spatula.
0:23:15 > 0:23:17Then we'll pick it up carefully.
0:23:17 > 0:23:19- Well, shall we see if it works? - ALL: Yes.
0:23:19 > 0:23:22Let's do it, your time starts now.
0:23:22 > 0:23:23ALARM BLARES
0:23:23 > 0:23:26- You open the jar.- Yes, let's open the jar, that's a good...
0:23:29 > 0:23:32You need to estimate the size of the spatula.
0:23:34 > 0:23:38It's not big enough, we can't do it. We can't do it, it's not...
0:23:38 > 0:23:40And right, OK, now you've got...
0:23:40 > 0:23:42That's it, now dig, dig, dig.
0:23:42 > 0:23:44Dig for victory. Here we go.
0:23:44 > 0:23:46ALARM BLARES
0:23:46 > 0:23:50Oh! Oh, I'm afraid that's a little bit of rice, isn't it?
0:23:50 > 0:23:53Oh, the Atomic Atoms got overcomplicated.
0:23:53 > 0:23:56They spent too much time sawing, only to find their plan was
0:23:56 > 0:24:00plainly not working. Spatula, but not spectacular.
0:24:03 > 0:24:05So, my fine friends,
0:24:05 > 0:24:07I can now reveal the result of that round.
0:24:07 > 0:24:10Actually, none of you managed to get the tomato out,
0:24:10 > 0:24:13which means no points for anybody, I'm afraid.
0:24:13 > 0:24:15Now, do you remember? When I briefed you on this,
0:24:15 > 0:24:19I said you could either use any two of the implements
0:24:19 > 0:24:22or a clever scientific way.
0:24:22 > 0:24:25Mmmm. Well, I can reveal at this point,
0:24:25 > 0:24:29- the Blue Team are going to kick themselves.- Oh, no!
0:24:29 > 0:24:32- Because you remember you did this? - ALL: Yeah.
0:24:32 > 0:24:35Have a little look, son.
0:24:35 > 0:24:38- Da-da-da-dum-dum. We'll get there. - Halfway, it's halfway.
0:24:38 > 0:24:40- I knew it!- Here it comes.- I knew it!
0:24:41 > 0:24:44- Nearly there. There we go.- Oh!
0:24:46 > 0:24:48- There she is.- Well done!
0:24:48 > 0:24:54I present my new sculpture, Smug Monkey Looking at a Tomato.
0:24:54 > 0:24:56Our secret sciencey method was all about a thing called
0:24:56 > 0:24:58granular convection.
0:24:58 > 0:25:02Shaking the jar makes the tiny grains of rice fall down around
0:25:02 > 0:25:07the larger tomato, settling under it and sending it rising to the top.
0:25:07 > 0:25:10If only the Blues had got the jar up the right way!
0:25:10 > 0:25:11But they didn't, so they lost.
0:25:11 > 0:25:15Now, as the final round of exciting science approaches, let's find out
0:25:15 > 0:25:18what the score is, with that little thing I call "the scores".
0:25:18 > 0:25:20APPLAUSE
0:25:20 > 0:25:22The Golden Era shining on 10,
0:25:22 > 0:25:23the Atomic Atoms
0:25:23 > 0:25:25not far behind on a quantum 5,
0:25:25 > 0:25:27and the Terrific Tree Trio
0:25:27 > 0:25:28are looking pretty feisty on 15.
0:25:28 > 0:25:30It's still all to play for
0:25:30 > 0:25:31on Ultimate Brain.
0:25:38 > 0:25:41Ha-ha-ha-ha! So it's points to play for,
0:25:41 > 0:25:44and honour most awesome is the prize.
0:25:44 > 0:25:46Remember, 2 points for each correct answer,
0:25:46 > 0:25:49nothing for a wrong answer, not even an old toffee
0:25:49 > 0:25:51covered in pocket fluff. Ready, GP?
0:25:51 > 0:25:55- Ready, DB. - Hands on desks, let's do this thing.
0:25:55 > 0:25:57The world's largest machine, the large Hadron Collider,
0:25:57 > 0:26:00smashes what together - atomic particles or dinner plates?
