0:00:05 > 0:00:09What happens when hot cans become cold cans?
0:00:09 > 0:00:14Can Guinea Pig walk the walk when there is only water to walk on?
0:00:14 > 0:00:18And can this week's brains send GP's letters faster than a text?
0:00:19 > 0:00:23Set your brains to genius, turn up the fun dial to 11 and have
0:00:23 > 0:00:28your most thinky thoughts at the ready, it is time for Ultimate Brain.
0:00:37 > 0:00:40HE LAUGHS EVILLY
0:00:40 > 0:00:44Hi, there, my name is Dr Brain and my goal is to find
0:00:44 > 0:00:48extreme cleverness and eye-popping levels of genius.
0:00:48 > 0:00:52My tools are spectacular science, excellent experiments
0:00:52 > 0:00:54and supermodel good looks.
0:00:54 > 0:00:56Watch me now.
0:00:56 > 0:00:58DANCE MUSIC
0:00:58 > 0:01:02Yes, this is Ultimate Brain.
0:01:08 > 0:01:09Let's meet the magnificent minds
0:01:09 > 0:01:11hoping to excel in today's experiments.
0:01:11 > 0:01:14From Birmingham, they're green as grass and bright as buttons, it's...
0:01:19 > 0:01:23They're yellow but they're no bunch of lemons.
0:01:27 > 0:01:32And our famous faces in Team Blue are from CBBC's Officially Amazing.
0:01:39 > 0:01:41This week's teams are no ordinary humanoids,
0:01:41 > 0:01:44they are the greatest, mighty-minded brainboxes from across the land,
0:01:44 > 0:01:47here to compete in the name of science for points,
0:01:47 > 0:01:49but more importantly for honour.
0:01:49 > 0:01:51First we have our Green Team.
0:01:51 > 0:01:53Dr Sofia, would you like to invent anything?
0:01:53 > 0:01:55A time machine.
0:01:55 > 0:01:59Ooh, and what kind of time would you like to go backwards or forwards to?
0:01:59 > 0:02:03I would probably go forwards and then see what happens in the
0:02:03 > 0:02:07future, like, if they really do invent flying cars and then I'd take
0:02:07 > 0:02:11one back to now and then I'd be the only person with a flying car.
0:02:11 > 0:02:14If I had a time machine, do you know where I'd go back to?
0:02:14 > 0:02:15Breakfast time.
0:02:15 > 0:02:17Mmm, bananas.
0:02:17 > 0:02:20Thank you, that's the Green Team,
0:02:20 > 0:02:23who shall be known to us as... What is your team name?
0:02:23 > 0:02:25- ALL:- Rays of Radiation.
0:02:25 > 0:02:28Rays of Radiation, wonderful.
0:02:28 > 0:02:31Here we have the yellows, Dr Charlie...
0:02:31 > 0:02:34- Yes, hello. - What would you like to invent?
0:02:34 > 0:02:37- I would like to invent a teleporter. - DR BRAIN GASPS
0:02:37 > 0:02:39If you could beam yourself to somewhere,
0:02:39 > 0:02:41where would you beam yourself to?
0:02:41 > 0:02:44- Probably New Zealand. - Oh, why particularly there?
0:02:44 > 0:02:46Because my family live over there.
0:02:46 > 0:02:49- Well, presumably not all of them? - No, some live here.
0:02:49 > 0:02:50# Half live here And half live there
0:02:50 > 0:02:53# I wonder Where the other one's gone. #
0:02:53 > 0:02:54Marvellous! What is your team name?
0:02:54 > 0:02:56- ALL:- The Brain Busters.
0:02:56 > 0:02:59The Brain Busters! Are you going to bust some brains today?
0:02:59 > 0:03:01- Let's hope.- Yep. - Thank you, there they are.
0:03:01 > 0:03:04Do you know, I am Officially Amazed to be standing next to you guys
0:03:04 > 0:03:07and I can't think why, why would that be?
0:03:07 > 0:03:09- Hmmm, why?- I don't know.
0:03:09 > 0:03:11Because we are Officially Amazing?
0:03:11 > 0:03:15Oh, that's what it is, you are the team from Officially Amazing,
0:03:15 > 0:03:18one of the great programmes on this wonderful channel called CBBC.
0:03:18 > 0:03:20Dr Ben,
0:03:20 > 0:03:24- I hear you like old things. - I do, I do.
0:03:24 > 0:03:26- I am a big history buff...- Oh, yes. - ..so I like artefacts.
0:03:26 > 0:03:29- I'm wearing a Roman ring with a tiny little face on it.- Oh!
0:03:29 > 0:03:31I don't know who he was,
0:03:31 > 0:03:33but he was startled when they made him into a ring.
0:03:33 > 0:03:36But Dr Haruka, I have heard that although you have
0:03:36 > 0:03:38a heart in your hair for me, I've also heard...
0:03:38 > 0:03:40IN COCKNEY ACCENT: You're hard as nails!
0:03:40 > 0:03:42- Is that right?- That's right. - Oh, I'm a little bit scared!
0:03:42 > 0:03:45- You do a few martial arts, do you? - I do indeed, quite a few.
0:03:45 > 0:03:49Kendo, Aikido, Judo, Taekwondo, you name it, I've done it all.
0:03:49 > 0:03:50Sizzling Steve...
0:03:50 > 0:03:52That's me.
0:03:52 > 0:03:54How are you today?
0:03:54 > 0:03:56- Hot.- It's going to get hotter. - Of course.
0:03:56 > 0:03:58Our Officially Amazing Team.
0:03:58 > 0:04:00Right, are you ready, teams?
0:04:00 > 0:04:02- ALL TEAMS:- Yeah!
0:04:02 > 0:04:05Let's do it, it's time for Round 1.
0:04:11 > 0:04:14Here we are, then, teams, with our first challenge.
0:04:14 > 0:04:19Now, this Brain Ignition challenge involves hot and cold water.
0:04:19 > 0:04:21Behold!
0:04:23 > 0:04:25- It is just some cans, isn't it?- Yeah.
0:04:25 > 0:04:27That was a bit overdramatic, really, for some cans.
0:04:27 > 0:04:29It's just four empty cans.
0:04:29 > 0:04:33Well, almost empty cos they each have a little bit of hot water in them
0:04:33 > 0:04:37and what do you think would happen if we heat that bit of hot water up
0:04:37 > 0:04:43and then plunge them upside down into this big tub of icy cold water here?
0:04:43 > 0:04:45Look at the confusion on their faces.
0:04:45 > 0:04:49We are going to give them four choices. Will these cans...
0:04:49 > 0:04:52A - Increase the temperature of this tub of water
0:04:52 > 0:04:55by exactly 1 degree Celsius?
0:04:55 > 0:05:00B - Will they all expand and become massive cans?
0:05:02 > 0:05:07C - Crush inwards like the invisible man has given them a bashing?
0:05:07 > 0:05:12Or D - Something else entirely different?
0:05:12 > 0:05:15OK, teams, your thinking time starts now.
0:05:19 > 0:05:23Hmm, just four choices here, should be pretty easy, don't you think?
0:05:23 > 0:05:25Have you thought of your answer?
0:05:25 > 0:05:28THEY TALK AMONGST THEMSELVES
0:05:28 > 0:05:32OK, OK, teams, that's it, time is up, no more thinking,
0:05:32 > 0:05:37you've thunk your thoughts. Now it is time to reveal your answers.
0:05:37 > 0:05:41Now! Let's see what you all thought What have we got, what have we got?
0:05:41 > 0:05:45D and a C and C.
0:05:45 > 0:05:47Well, let's start with this C over here.
0:05:47 > 0:05:50Let's see why they said C.
0:05:52 > 0:05:55Well, I thought it was the same as the body muscle,
0:05:55 > 0:05:59your body is hot and when you jump into the cold pool water,
0:05:59 > 0:06:03you will go, ooh, like that, it is the same.
0:06:03 > 0:06:05Oh, I see, I like your thinking.
0:06:05 > 0:06:08Yellows, you have gone for C as well, are you thinking the same
0:06:08 > 0:06:11thing or is it different science thoughts going on?
0:06:11 > 0:06:13Kind of, we thought that the molecules on the inside...
0:06:13 > 0:06:17Sudden cooling would weaken them so the molecules on the outside
0:06:17 > 0:06:19would crush the can.
0:06:19 > 0:06:24Oh, I see, so the molecules that are inside the cans will be sort of
0:06:24 > 0:06:28constricted by the power of the molecules on the outside of the can.
0:06:28 > 0:06:30- Yeah.- Oh, that is pretty interesting, isn't it?
0:06:30 > 0:06:33Now, then, Dr Lauren.
0:06:33 > 0:06:34I thought...
0:06:34 > 0:06:37We all thought, it would collect like steam cos it is
0:06:37 > 0:06:41cooling down when it hits the cold and the hot... Mixed temperatures.
0:06:41 > 0:06:44I see, so when it goes in it is all going to go whoosh
0:06:44 > 0:06:47- and sort of bubble and steam and go a bit mad and crazy.- Yes.
0:06:47 > 0:06:50I see. We got some pretty interesting thoughts, I think, there.
0:06:50 > 0:06:53Let's what actually happens when we add hot water
0:06:53 > 0:06:56and then turn these cans upside down into cold water.
0:06:56 > 0:06:58Ah-di-dah-di-dah!
0:06:58 > 0:07:02Ah, beautiful. Protective gloves - check. Protective goggles - check,
0:07:02 > 0:07:04handsome face - double check.
0:07:04 > 0:07:07This is officially dangerous, folks. Do not try this at home.
0:07:07 > 0:07:09Are you ready? Here we go.
0:07:14 > 0:07:16So, the amazing answer was -
0:07:16 > 0:07:20C - The cans would become instantly crushed.
0:07:20 > 0:07:23So when I plunged the cans into the cold water, the steam inside them
0:07:23 > 0:07:26was very quickly turned back into water.
0:07:26 > 0:07:30This meant the inside of the cans had less push than the air around them.
0:07:30 > 0:07:32It is all about pressure, you see.
0:07:32 > 0:07:33Air can be pretty strong,
0:07:33 > 0:07:35so these poor little cans didn't stand a chance.
0:07:35 > 0:07:37Oh, bless 'em!
0:07:37 > 0:07:42Ha-ha-ha. So, there we go, five points for the Yellows and the Blues.
0:07:48 > 0:07:51Next up, the Creative Challenge.
0:07:51 > 0:07:55Yes, it's time to put your brains into a different gear.
0:07:55 > 0:07:59Creative thinking is the key to collecting the points in this round.
0:07:59 > 0:08:04Ha-ha! We call this challenge the Ultimate Brain Fashion Catwalk.
0:08:04 > 0:08:07Yes, it is Ultimate Brain Fashion Week and we are bringing some
0:08:07 > 0:08:11much-needed science to the glamorous world of the catwalk.
0:08:12 > 0:08:15Sadly, Kate Moss has stopped taking my calls, but fear not,
0:08:15 > 0:08:19we have someone with even more style, even more grace, yes, it is
0:08:19 > 0:08:22Ultimate Brain's very own supermodel, Guinea Pig.
0:08:24 > 0:08:27CHEERING
0:08:36 > 0:08:38Erm, Guinea Pig, Guinea Pig, what are you doing?
0:08:38 > 0:08:39What does it look like?
0:08:39 > 0:08:43I'm showcasing my fantastic golden tracksuit on the catwalk.
0:08:43 > 0:08:46No, no, no, no, no, no, no, no.
0:08:46 > 0:08:50No! That's not the catwalk, that is a tester from the local carpet shop.
0:08:50 > 0:08:54I'm thinking about getting the whole studio floor done in it, you see.
0:08:54 > 0:08:57No, no, no, your catwalk, my friend, is here.
0:08:57 > 0:08:58HE LAUGHS EVILLY
0:09:01 > 0:09:04The Ultimate Brain catwalk is a water tank?
0:09:04 > 0:09:08But I'm going to get my fabulous golden tracksuit completely soggy!
0:09:08 > 0:09:11Fear not, GP, the teams have been set the creative
0:09:11 > 0:09:14challenge of designing you footwear, you see, that will take you
0:09:14 > 0:09:17the length of this watery catwalk without getting you wet. Ha-ha!
0:09:17 > 0:09:19Our teams were given two days
0:09:19 > 0:09:24and a budget of £50 to design a solution to this challenge.
0:09:24 > 0:09:26In this wacky water challenge, our teams will need to consider
0:09:26 > 0:09:30weight and size... That's right, off you go, GP, don't be scared!
0:09:30 > 0:09:33If their designs can shift aside more than 66 litres of water...
0:09:33 > 0:09:38Cor, what a lot of water! Yes, that's 66kg, the same weight as Guinea Pig,
0:09:38 > 0:09:42..then there will be enough upwards force to keep him afloat.
0:09:42 > 0:09:45They need to think big, lightweight and balanced
0:09:45 > 0:09:47if they hope to succeed like these inflatable shoes.
0:09:47 > 0:09:50Whoops, sorry, Guinea Pig.
0:09:50 > 0:09:54Now, the team that gets GP the furthest across the water
0:09:54 > 0:09:56wins the most points.
0:09:56 > 0:09:59First up, it's the Blues.
0:09:59 > 0:10:01Behold!
0:10:04 > 0:10:08- Look at this.- This is our sensational flotational contraption.
0:10:08 > 0:10:11The idea is that he's meant to be inside it, in the middle, that is,
0:10:11 > 0:10:14and he should just be able to float onto the water
0:10:14 > 0:10:15and just paddle along.
0:10:15 > 0:10:19Oh, I see. So what are these sort of design box things?
0:10:19 > 0:10:21- They're polystyrene...- Ah, I see.
0:10:21 > 0:10:23..so they've got flotational properties.
0:10:23 > 0:10:28Oh, flotational properties. And what is the actual name of your plan?
0:10:28 > 0:10:30Operation Don't Sink?
0:10:30 > 0:10:32Operation Don't Sink.
0:10:32 > 0:10:35Team Officially Amazing's plan is to suspend Guinea Pig
0:10:35 > 0:10:38above the water completely, using large, light,
0:10:38 > 0:10:40highly floaty polystyrene blocks...
0:10:40 > 0:10:43BABY VOICE: ..so that he can paddle his ittle-little footies
0:10:43 > 0:10:45and cross the pool.
0:10:45 > 0:10:48Do you think it's going to work? Let's find out.
0:10:48 > 0:10:51- Get ready, Guinea Pig. - I was born ready, Dr Brain.
0:10:51 > 0:10:53Get on with it then, son!
0:10:55 > 0:10:59Officially Amazing idea is officially awful.
0:10:59 > 0:11:04Water walking frame sinks without a trace. It is a creative catastrophe.
0:11:04 > 0:11:06Contestants are in shock at wet Guinea Pig.
0:11:14 > 0:11:15The Latin term for this is
0:11:15 > 0:11:18break-us apart-icus load of old rubbish-icus.
0:11:18 > 0:11:20What a disaster for the Blues.
0:11:20 > 0:11:24They went for maximum flotation and stability, but they went too far.
0:11:24 > 0:11:26As GP tried to get into position,
0:11:26 > 0:11:30so much force was required to push the polystyrene under the water
0:11:30 > 0:11:33that their flimsy structure couldn't take the pressure,
0:11:33 > 0:11:35causing a complete catastro-collapse.
0:11:35 > 0:11:38Iceberg dead ahead!
0:11:38 > 0:11:42I think perhaps we might have to abandon this little plan, don't you?
0:11:42 > 0:11:45- We agree.- Zero points there for the Blues, it didn't quite work.
0:11:45 > 0:11:48That's science, folks, what are you going to do?
0:11:49 > 0:11:52Here we have the Yellow plan.
0:11:52 > 0:11:54It's got to be better than the Blues', hasn't it?
0:11:54 > 0:11:58So, Dr Noah, have you ever built a big wooden boat
0:11:58 > 0:12:00and filled it with two of every type of animal
0:12:00 > 0:12:03and then floated it across a massive sea cos there was a flood coming?
0:12:03 > 0:12:07- No, but it's not to say it won't happen.- That was a different Noah.
0:12:07 > 0:12:11- So, what is your plan here? - Well, we have tripod stilts.
0:12:11 > 0:12:15Tripod stilts, how marvellous. What are they for, the tripod stilts?
0:12:15 > 0:12:18To support Guinea Pig in the water.
0:12:18 > 0:12:21So you are not going to try to float him across?
0:12:21 > 0:12:23- ALL:- No. - What is the pole for?
0:12:23 > 0:12:26The pole is just in case he falls one way,
0:12:26 > 0:12:27he can push himself back up.
0:12:27 > 0:12:30This design aims to bypass the floating stuff altogether
0:12:30 > 0:12:34by supporting Guinea Pig above the water on tripod stilts
0:12:34 > 0:12:38with a pole for added balance, but can GP stay high and dry?
0:12:42 > 0:12:43- Are you ready, Guinea Pig?- No.
0:12:43 > 0:12:47Get on with it in three, two, one.
0:12:47 > 0:12:51Go, Guinea Pig. You can egg him on.
0:12:51 > 0:12:53THEY SHOUT ENCOURAGEMENT
0:12:53 > 0:12:56You can knock him, if you like, as well. I always like that!
0:12:56 > 0:12:57Not very good, Guinea Pig.
0:12:57 > 0:13:00Getting himself into position. Oh, a little wobble.
0:13:00 > 0:13:01Use the pole to balance.
0:13:01 > 0:13:04- Ah, he is using it there.- Yes. So he wins the race.
0:13:06 > 0:13:09Oh, now, that looks quite difficult to push.
0:13:09 > 0:13:13Yes, of course because one litre of water weighs a kilogram so that's
0:13:13 > 0:13:17quite a lot of litres. It's a lot of weight he has to push against.
0:13:17 > 0:13:19- He's doing well. - He's doing pretty well.
0:13:22 > 0:13:24THEY LAUGH
0:13:25 > 0:13:29The Yellows cleverly tried to avoid the issue of balance and buoyancy
0:13:29 > 0:13:32with their tricky tripod stilts and pole for added balance.
0:13:32 > 0:13:34The tripod is a very stable structure,
0:13:34 > 0:13:36but, unfortunately, these wooden
0:13:36 > 0:13:39wonders are light enough to actually float on their own. This meant,
0:13:39 > 0:13:41for every step GP took, the stilts would try to escape
0:13:41 > 0:13:43out from under the him.
0:13:43 > 0:13:46I don't blame them, would you want to be near his stinky feet? Eurrggh!
0:13:46 > 0:13:48Oh, unlucky. That was a pretty good try,
0:13:48 > 0:13:52I liked the theory behind it and I liked your design.
0:13:52 > 0:13:55I think the Guinea Pig factor let you down there. Do you blame him?
0:13:55 > 0:13:57- ALL:- Yes.
0:13:57 > 0:13:59I blame him as well. That was pretty good.
0:13:59 > 0:14:03- So, what do you think went wrong? - Balance issue.- Balance issue.
0:14:03 > 0:14:07- Maybe the pole was either too far or too close to him.- Maybe, yes.
0:14:07 > 0:14:09There was a lot of effort involved.
0:14:09 > 0:14:11Was that quite hard, doing that, Guinea Pig?
0:14:11 > 0:14:15I think it was fine up until the point that I got wet.
0:14:15 > 0:14:16DR BRAIN LAUGHS
0:14:16 > 0:14:19Well, you might have to get used to that, Guinea Pig, cos you might
0:14:19 > 0:14:24be doing it again, because now it is the turn of the Greens.
0:14:24 > 0:14:26So, we have a complete failure by the Blues,
0:14:26 > 0:14:29the Yellows have got about just under halfway, we think so.
0:14:29 > 0:14:33How are the Greens going to do? What is your plan called?
0:14:33 > 0:14:37- Amazing Aqua Feet.- Amazing Aqua Feet. Talk me through it.
0:14:37 > 0:14:42- So, basically, our plan is, it's got a large surface area...- Yes.
0:14:42 > 0:14:44- ..and a block underneath to keep it balanced...- Ah, yes.
0:14:44 > 0:14:46..so hopefully it will float
0:14:46 > 0:14:50and then the paddle is there to either help him go along as
0:14:50 > 0:14:53he is gliding, like roller-skates but without the wheels.
0:14:53 > 0:14:54You are going to glide.
0:14:54 > 0:14:56You have thought this through, haven't you?
0:14:56 > 0:14:59You've discussed this, you've used your time well.
0:14:59 > 0:15:01Now, are you confident that this can work?
0:15:01 > 0:15:02- ALL:- Yes.
0:15:02 > 0:15:04Don't forget, you got Guinea Pig doing it.
0:15:04 > 0:15:07So there's always the Guinea Pig factor.
0:15:07 > 0:15:10The Green plan is to make two highly floaty feet for Guinea Pig to
0:15:10 > 0:15:12literally walk on water.
0:15:12 > 0:15:15Wow, that looked awesome. But will it work?
0:15:15 > 0:15:19Well, you know, I think there's only so much talkin' you can do
0:15:19 > 0:15:21when you just got to start walkin'.
0:15:21 > 0:15:25Three, two, one, go, Guinea Pig!
0:15:25 > 0:15:27Now, you can egg him on. ALL SHOUT ENCOURAGEMENT
0:15:27 > 0:15:31- Get up a little bit. - You need the paddle.
0:15:31 > 0:15:35- And push yourself up. - Does he need to stand or sit or...
0:15:37 > 0:15:39ALL SHRIEK
0:15:40 > 0:15:42APPLAUSE
0:15:43 > 0:15:47- What do you think went wrong? - Everything.- Everything.
0:15:47 > 0:15:49- I think the paddle was good. - The paddle was good.
0:15:49 > 0:15:51Yes, he was doing quite well.
0:15:51 > 0:15:53I think it was just a bit too much polystyrene.
0:15:53 > 0:15:56The Green team put their best foot forward with their amazing
0:15:56 > 0:15:58polystyrene aqua-feet.
0:15:58 > 0:16:01This very lightweight material is perfect for moving aside
0:16:01 > 0:16:04as much water as possible without adding extra weight.
0:16:04 > 0:16:05Oh, if only they'd tied them
0:16:05 > 0:16:08together to stop Guinea Pig's legs from being forced apart.
0:16:08 > 0:16:10Ha-ha-ha!
0:16:10 > 0:16:13Oh, dear. Guinea Pig, you look very, very soggy.
0:16:13 > 0:16:16But you're still kind of shiny and golden. I like that about you.
0:16:16 > 0:16:17Ha-ha-ha!
0:16:17 > 0:16:21But I've got to give five points for a valiant effort to the Yellows!
0:16:21 > 0:16:24CHEERING
0:16:30 > 0:16:34Pesky fly! Gotcha! Ha-ha-ha!
0:16:34 > 0:16:36Yes, this round is all about quick reactions, you see?
0:16:36 > 0:16:39Thankfully, our teams have lightning-fast reactions.
0:16:39 > 0:16:43Even hummingbirds appear sloth-like in their presence.
0:16:43 > 0:16:44Who will be the quickest?
0:16:44 > 0:16:48Even my amazing monkey vision cannot accurately answer that question.
0:16:48 > 0:16:51Which means it's time to bring out
0:16:51 > 0:16:56the Sloooowwwwmoniiiiizerrr...
0:16:56 > 0:17:01Yes, this supercool camera records in super...very...slow...motion...
0:17:01 > 0:17:05so that I can accurately see who the winner is going to be.
0:17:05 > 0:17:08Now, the Slinky rules are that you must hang your arms over
0:17:08 > 0:17:13the ultimate pole so that all arms are at exactly the same height.
0:17:13 > 0:17:17Now, when you hear Dr Brain's sound of the week - eek-eek! -
0:17:17 > 0:17:21you drop your Slinkys and the first to let go wins. Are we confident?
0:17:21 > 0:17:23- Are we happy?- Yep.- Very good.
0:17:29 > 0:17:31Ready?
0:17:32 > 0:17:35Eek-eek!
0:17:35 > 0:17:39Wow! Now, that was pretty good. I think you were all pretty quick.
0:17:39 > 0:17:44Let's take another look at that seriously speedy Slinky action there.
0:17:44 > 0:17:46But who dropped first?
0:17:46 > 0:17:50Even my super monkey vision can't tell who was first
0:17:50 > 0:17:51when they are that quick.
0:17:51 > 0:17:54So there's only one way to be sure of this -
0:17:54 > 0:17:58activate the Slowmonizer!
0:17:58 > 0:18:01Wow, look at that!
0:18:01 > 0:18:02The bottoms of the Slinkys wait
0:18:02 > 0:18:04for the tops to catch up with them in midair.
0:18:04 > 0:18:08Come on, mate! Only then will they fall to the ground.
0:18:08 > 0:18:10Yes, there we go.
0:18:10 > 0:18:13It's a pretty clear result.
0:18:13 > 0:18:16He cheered and he was right to cheer.
0:18:16 > 0:18:18It was Yellow! Well done!
0:18:18 > 0:18:20Ten points to the Yellows!
0:18:20 > 0:18:21CHEERING
0:18:33 > 0:18:36Grrrrrrr! A little bit of dinosaur acting there.
0:18:36 > 0:18:39I don't know why I did that. I just fancied it, so I did it.
0:18:39 > 0:18:41My show - I can do what I like, can't I?
0:18:41 > 0:18:44Now, it's time for our teams to engage their brains again.
0:18:44 > 0:18:48It's the Inspiration Challenge! Ha-ha-ha!
0:18:48 > 0:18:50Sorry, just one moment, please.
0:18:50 > 0:18:52I won't be home for dinner tonight, Mumsie,
0:18:52 > 0:18:54going to my balloon dancing class.
0:18:54 > 0:18:57Who knew dancing and blowing balloons at the same time could be
0:18:57 > 0:18:59so much fun?
0:18:59 > 0:19:01Right, that's done. And...send.
0:19:03 > 0:19:04There we go.
0:19:04 > 0:19:07I never could quite get the hang of the old texting thing there.
0:19:07 > 0:19:09I don't think I even put a stamp on.
0:19:09 > 0:19:13But can the teams get my letters across the Ultimate Brain studio
0:19:13 > 0:19:16faster than a speeding text message?
0:19:16 > 0:19:21And the team whose rocket travels the furthest wins!
0:19:21 > 0:19:24You each have a 50cm-long paper tube
0:19:24 > 0:19:28which you must adapt to make it more streamlined, you see,
0:19:28 > 0:19:31using this fine array of rocket-building materials
0:19:31 > 0:19:33that you have here.
0:19:33 > 0:19:37Now, you have five minutes to design and build your rockets.
0:19:37 > 0:19:38Pretty good, huh?
0:19:38 > 0:19:40ALL: Yes! Ready?
0:19:40 > 0:19:41ALL: Yes! Up for it?
0:19:41 > 0:19:43ALL: Yes! Feeling confident?
0:19:43 > 0:19:44ALL: Yes! Then let's do it.
0:19:44 > 0:19:46Your time starts...
0:19:46 > 0:19:47now!
0:19:48 > 0:19:53- ..on the tip of here.- A point.
0:19:53 > 0:19:55If you think of it like a paper aeroplane,
0:19:55 > 0:19:59- a paper aeroplane flies well because it's got straight lines.- Yeah.
0:19:59 > 0:20:02We have to make a 3-D triangle on each end.
0:20:02 > 0:20:05I think we need to put a cone on the front and then stuff that so...
0:20:05 > 0:20:07Yeah.
0:20:07 > 0:20:10The teams' rockets will be fired across the studio
0:20:10 > 0:20:13using compressed air.
0:20:13 > 0:20:14Yes, yes.
0:20:14 > 0:20:18Our teams will have to think about the weight of their rocket
0:20:18 > 0:20:20and how well it will cut through the air.
0:20:20 > 0:20:23This is aerodynamics in action, folks.
0:20:23 > 0:20:25Stick that on the wing.
0:20:25 > 0:20:27Just... Yeah.
0:20:27 > 0:20:29We need a....
0:20:29 > 0:20:31Like an arrow. Let's call it the Arrow.
0:20:31 > 0:20:36- This is nice, this is nice. - This is good! Officially amazing!
0:20:36 > 0:20:39- And again, and again. More, more, more.- We need more wings, but...
0:20:39 > 0:20:41It's fine.
0:20:41 > 0:20:45KLAXON Time's up. Everybody, stop working!
0:20:45 > 0:20:49And I think you've got some stratospheric science going on here.
0:20:49 > 0:20:52But it's time to get testing!
0:20:52 > 0:20:55Hm... The Blue rocket...
0:20:55 > 0:20:57Now, who could that belong to?
0:20:57 > 0:20:59Ohhh! There you are!
0:20:59 > 0:21:00You frightened the life out of me!
0:21:00 > 0:21:03It's the Blues! So what have you come up with?
0:21:03 > 0:21:06- It's a kind of a floppy rocket. - Floppy rocket?- Yeah.
0:21:06 > 0:21:09We got the wings the wrong way round to the way it's going
0:21:09 > 0:21:11to travel, so it's sort of dangling a little bit.
0:21:11 > 0:21:13But it will still work.
0:21:13 > 0:21:14Probably loads of air resistance there -
0:21:14 > 0:21:16- so just what we're looking for(!) - Very good.
0:21:16 > 0:21:19There's only one thing to do - get pumping!
0:21:19 > 0:21:20Come on, Ben.
0:21:20 > 0:21:25Now, Dr Chris will give us the nod when we're at optimum pressure.
0:21:25 > 0:21:32Here we go. Counting down to release. And three, two, one, fire!
0:21:33 > 0:21:34ALL EXCLAIM
0:21:34 > 0:21:38Look at that! That's pretty good.
0:21:38 > 0:21:41You're only just shy of the target.
0:21:41 > 0:21:44The Team Officially Amazing rocket sped across the studio.
0:21:44 > 0:21:48Its pointy nose helped it through the air and wings gave it stability.
0:21:48 > 0:21:49Great job!
0:21:49 > 0:21:52Well done, Blues! Who's next?
0:21:52 > 0:21:56Oh, Yellow team, I can see you've already taken your positions.
0:21:56 > 0:21:58You know your team roles you're playing.
0:21:58 > 0:22:02- Dr Archie, you've obviously been nominated as the pumper.- Yeah.
0:22:02 > 0:22:05- You happy with that?- Yes. - Think you can do it?- Hope so.
0:22:05 > 0:22:08- And Dr Noah, you're going to be the releaser.- Yeah.
0:22:08 > 0:22:11And Dr Charlie, you're going to supervise and oversee,
0:22:11 > 0:22:14- adjudicate and assess.- I am indeed. - You're the boss guy, right?
0:22:14 > 0:22:16- Yes.- Tell everybody what to do.
0:22:16 > 0:22:19- So, what are we calling this? - The Arrow.- The Arrow.
0:22:19 > 0:22:21Sounds like a movie starring Nicolas Cage.
0:22:21 > 0:22:24GRUFFLY: "You can't fire that rocket, my daughter's on board."
0:22:24 > 0:22:28- So, I can see it's got kind of wing-type things.- Yeah.
0:22:28 > 0:22:31And the feathers are going to give it a bit of extra edge, yes?
0:22:31 > 0:22:35- Hopefully.- Good. Let's get going, then. Start your pumping now!
0:22:42 > 0:22:47We are at optimum pressure. It is now time to count down to release.
0:22:47 > 0:22:51Are you ready? Three, two, one, fire!
0:22:51 > 0:22:53ALL EXCLAIM
0:22:53 > 0:22:55- Oh, look at that!- We lose.
0:22:55 > 0:22:58Your nose cone was a little bit lumpy, wasn't it?
0:22:58 > 0:23:01- Yeah.- That made it not too aerodynamic?- possibly.
0:23:01 > 0:23:03- Because it shot out really well, didn't it?- Yes.
0:23:03 > 0:23:05- And then it sort of...stopped. - Kind of fell.
0:23:05 > 0:23:08- Yes, it kind of drooped a bit, didn't it?- It was top-heavy.
0:23:08 > 0:23:10It went, "Yayyyy... I've had enough."
0:23:10 > 0:23:13The Yellows had the right idea with their pointed nose
0:23:13 > 0:23:17and stabilising wings, but with the nose pointing slightly upwards
0:23:17 > 0:23:18and the wings on the bottom,
0:23:18 > 0:23:22there was too much air dragging underneath the rocket,
0:23:22 > 0:23:25forcing it up and grinding to a halt.
0:23:25 > 0:23:27Pretty good effort, though, lads. Are you pleased?
0:23:27 > 0:23:29ALL: Yes. You should be.
0:23:29 > 0:23:32Now let's see the team of the Greens.
0:23:32 > 0:23:34Look at the Greens - they're raring to go.
0:23:34 > 0:23:37They're champing at the bit and so am I. I can't wait to see this work.
0:23:37 > 0:23:40So, you've got a nose cone, you've got wings, feathers.
0:23:40 > 0:23:41What are you calling it?
0:23:41 > 0:23:44ALL: Pocahontas. Perfect name.
0:23:44 > 0:23:49There's nothing more to do but fire it. Get pumping! Come on, let's go!
0:23:49 > 0:23:54That's it, good work. Put some muscle into it. Nice. Very good.
0:23:54 > 0:23:56Nearly there. Very good.
0:23:56 > 0:24:01Here we go. Three, two, one, fire!
0:24:01 > 0:24:03ALL EXCLAIM
0:24:03 > 0:24:06- Oh, no!- How is it?- Please...
0:24:06 > 0:24:08ALL GASP
0:24:08 > 0:24:11- It's a dead heat!- No!
0:24:11 > 0:24:14Exactly the same as the Blues!
0:24:14 > 0:24:17The Rays Of Radiation rocket had the same winning
0:24:17 > 0:24:19properties as the Officially Amazing one.
0:24:19 > 0:24:20But the straight nose cone
0:24:20 > 0:24:22had flights like a dart to help stability.
0:24:22 > 0:24:25It finished in exactly the same place as the Blue rocket.
0:24:25 > 0:24:27What are the chances, eh?
0:24:27 > 0:24:30Which means you spit the points between you.
0:24:30 > 0:24:33Yes, well done. Five points each to the Greens and the Blues!
0:24:33 > 0:24:34CHEERING
0:24:34 > 0:24:37Well done, everybody. I think you all did pretty well.
0:24:37 > 0:24:39Your messages were rocket-tastic.
0:24:39 > 0:24:42They were so fast, they arrived before they left!
0:24:42 > 0:24:44I'm overdoing it a bit there. Well done, everybody.
0:24:44 > 0:24:46CHEERING
0:24:46 > 0:24:49Now, as the final round approaches, let's find out what the score is
0:24:49 > 0:24:52with that little thing I call The Scores!
0:24:52 > 0:24:53CHEERING
0:24:53 > 0:24:55Team Officially Amazing on 10.
0:24:55 > 0:24:56Brain Busters on 20
0:24:56 > 0:24:59and Rays Of Radiation on... oh, 5.
0:24:59 > 0:25:04It's a close-run thing, but anyone can win on Ultimate Brain!
0:25:04 > 0:25:08# When I was just a tiny talking monkey with wisps of monkey hair
0:25:08 > 0:25:10# On my monkey head... #
0:25:10 > 0:25:13I dreamed of the future and the challenges that awaited me -
0:25:13 > 0:25:15climbing Mount Kilimanjaro in one hour,
0:25:15 > 0:25:18catching a meteor with my bare hands,
0:25:18 > 0:25:20looking after my amazing hairstyle.
0:25:20 > 0:25:24But never did I dream to reach such dizzy heights of greatness
0:25:24 > 0:25:28as I'm about to encounter in... the Quickfire Round!
0:25:32 > 0:25:35- Ready, GP?- I'm ready to go, Dr Brain!
0:25:35 > 0:25:38Fantastic, that's what I like to hear. Hands on your desks, everybody.
0:25:38 > 0:25:40Are you ready? ALL: Yes!
0:25:40 > 0:25:43Let's do this. You get two points for each correct answer.
0:25:43 > 0:25:45You get nothing, nothing, nothing for a wrong answer,
0:25:45 > 0:25:48not even one of GP's trumps in a jar. Here we go!
0:25:48 > 0:25:53Let's do it! Question one. Which is the only mammal that can fly?
0:25:53 > 0:25:55Yes, Blues.
0:25:55 > 0:25:56Ostrich?
0:25:56 > 0:26:00No, it's not ostrich! It's a bat!
0:26:00 > 0:26:01Nasa's Curiosity Rover probe
0:26:01 > 0:26:05is currently driving around taking selfies...
0:26:05 > 0:26:07Mars.
0:26:07 > 0:26:10- Correct!- Ho-ho! A rolling stone gathers what?
0:26:12 > 0:26:14- Blues.- No moss.
0:26:14 > 0:26:17Well, I'll give you that, but actually it's momentum.
0:26:17 > 0:26:18But you can get a bonus point.
0:26:18 > 0:26:23The name of which famous dinosaur actually means Tyrant Lizard King?
0:26:24 > 0:26:26- Tyrannosaurus Rex.- Correct!
0:26:26 > 0:26:29Why did the bacteria cross the microscope?
0:26:31 > 0:26:33To get to the other side?
0:26:33 > 0:26:36It was to get to the other SLIDE. Ha-ha!
0:26:36 > 0:26:39KLAXON Oh, that's time up, I'm afraid.
0:26:39 > 0:26:42There we go. Goodness me, that was quick. Even for the Quickfire Round.
0:26:42 > 0:26:45Well done, everybody. But which team was the winner?
0:26:45 > 0:26:48It's time for the results. Ready?
0:26:48 > 0:26:52- Are you excited, Guinea Pig? - I'm very excited, Dr Brain.- Me too.
0:26:52 > 0:26:56Here we go, then. In third place, with five points...it's the Greens!
0:26:56 > 0:26:57CHEERING
0:26:58 > 0:27:01Oh, commendable effort. Well done, well done.
0:27:01 > 0:27:05In second place, with 15 points, it's the Blue team!
0:27:05 > 0:27:06CHEERING
0:27:06 > 0:27:11Which means that our winners this week, with the Ultimate Brains,
0:27:11 > 0:27:13with 20 honour points, it's the Yellow team!
0:27:13 > 0:27:16CHEERING
0:27:16 > 0:27:17Smashing job, Yellow team.
0:27:17 > 0:27:20Wow! Amazing stuff there.
0:27:20 > 0:27:25It's honour you've won, and Ultimate Brain honour that you've won.
0:27:25 > 0:27:28Salute your victors, team. Well done, the Yellows!
0:27:28 > 0:27:29CHEERING AND APPLAUSE
0:27:29 > 0:27:31Fantastic.
0:27:31 > 0:27:34See you next time for more brain-expanding excellent experiments
0:27:34 > 0:27:36on...Ultimate Brain!
0:27:36 > 0:27:39CHEERING
