0:00:02 > 0:00:03We've got our work cut out here, GP.
0:00:03 > 0:00:05Oh, that reminds me...
0:00:05 > 0:00:08What's a balloon's least favourite drink?
0:00:08 > 0:00:11We've had a lot of balloons on Ultimate Brain
0:00:11 > 0:00:13and you know what? I've never thought to ask them
0:00:13 > 0:00:15what their least favourite drink might be.
0:00:15 > 0:00:16You know, we subject them to so much.
0:00:16 > 0:00:19And, you know what? Maybe I should ask them and become their friend.
0:00:19 > 0:00:21- No, GP... - Maybe they don't like water.
0:00:21 > 0:00:24Maybe they don't like milk, because, you know, it comes from cows,
0:00:24 > 0:00:25that might weird them out a bit.
0:00:25 > 0:00:28- GP!- Maybe we should go and ask the balloons. Hey, Mr Balloon.
0:00:28 > 0:00:30- Do you have any friends that... - No. No, it's...- ..we can go talk to?
0:00:30 > 0:00:32- And we can go learn more... - It's just a j...
0:00:32 > 0:00:34I feel a bit deflated now.
0:00:41 > 0:00:45Today, GP pumps it up.
0:00:45 > 0:00:48Which team's invention will be bursting with brilliance?
0:00:50 > 0:00:52And can our teams handle the pressure?
0:00:52 > 0:00:54Come on! Really?!
0:00:54 > 0:00:56Get those magnificent minds at the ready.
0:00:56 > 0:01:00It's time for Ultimate Brain!
0:01:00 > 0:01:04AUDIENCE CHEER
0:01:04 > 0:01:05HE LAUGHS
0:01:05 > 0:01:10Hi there. Ah, yes, the power of the internet.
0:01:10 > 0:01:13Yes. I've got my own website, you know?
0:01:13 > 0:01:15And I love vlogging on Oo-oo-ooTube.
0:01:15 > 0:01:18Hello. My name is Dr Brain.
0:01:18 > 0:01:21Today, I will be talking about my favourite hobbies,
0:01:21 > 0:01:25which include blogging, vlogging and clogging,
0:01:25 > 0:01:26which goes a little bit like this.
0:01:26 > 0:01:28Diddly-dee-diddly-dee-diddly-dee.
0:01:28 > 0:01:31Fiddly-dee-diddly-de-diddly-dee.
0:01:31 > 0:01:32Let's get on with the show!
0:01:32 > 0:01:34Fiddly-dee-diddly...
0:01:34 > 0:01:36Time to meet our teams.
0:01:36 > 0:01:37Uploading first, it's the Greens
0:01:37 > 0:01:39from Northern Ireland. It's...
0:01:42 > 0:01:45World Wide Web wise from Hampshire.
0:01:45 > 0:01:46It's...
0:01:49 > 0:01:53And our celebrity team, in blue, from CBBC's Whoops I Missed The Bus.
0:01:53 > 0:01:54It's Laura
0:01:54 > 0:01:57and the Mandeville sisters, Grace and Amelia.
0:01:57 > 0:01:59Here we go.
0:01:59 > 0:02:02HE GASPS It's time to meet the teams.
0:02:02 > 0:02:05Sorry, I'm a bit tired.
0:02:05 > 0:02:08I had to run here because, whoops, I missed the bus.
0:02:08 > 0:02:10Yes, it's the Blues!
0:02:10 > 0:02:12- How are you, Blues?- Good, thanks. - Good.- Very good.
0:02:12 > 0:02:14Good to meet you. You didn't miss the bus, did you?
0:02:14 > 0:02:18- You got here on time.- We certainly did.- We're here.- Marvellous!
0:02:18 > 0:02:21Now, then, Dr Laura, I hear you're a bit of a stand-up comedian.
0:02:21 > 0:02:24- Yeah.- What's easier, stand-up or vlogging?
0:02:24 > 0:02:27- Vlogging is definitely easier. - Definitely, yes, I should think so.
0:02:27 > 0:02:31Drs Mandeville, I believe you are rather experts in fashion,
0:02:31 > 0:02:33- are you not?- Yeah, we like fashion, - Yeah, we do.
0:02:33 > 0:02:35Yeah. What do you think of my fashion?
0:02:35 > 0:02:37I think you look bananas.
0:02:37 > 0:02:40Bananas! That's cos I shop at Dolce and Banana.
0:02:41 > 0:02:44Stop me now! What's your team name?
0:02:45 > 0:02:48Science Warriors!
0:02:48 > 0:02:50- OK, Yellows, how are you? - Good.- Fine.
0:02:50 > 0:02:53Now, then, Dr Harrison,
0:02:53 > 0:02:56I'm picking up a vibe that you're a bit of a comedian.
0:02:56 > 0:03:00Please welcome, next act, all the way from Ultimate Brain,
0:03:00 > 0:03:02Dr Harrison!
0:03:02 > 0:03:05I went to the airport, I tripped over some luggage and I went flying.
0:03:05 > 0:03:08Brilliant! What do you think of that, Dr Laura?
0:03:08 > 0:03:09I thought it was really good.
0:03:09 > 0:03:12Don't tell too many of your jokes, she'll probably steal them.
0:03:12 > 0:03:14HE LAUGHS
0:03:14 > 0:03:15What's your team name?
0:03:18 > 0:03:21Good to meet you, Yellows. Now then, the Greens.
0:03:21 > 0:03:24- Where are you from, Greens? ALL:- Northern Ireland.
0:03:24 > 0:03:26Dr Stephen, you want to be...
0:03:26 > 0:03:28a palaeontologist, is that right?
0:03:28 > 0:03:29- Yes.- Why so?
0:03:29 > 0:03:32Well, it's just fun to dig things up and you get to discover new things.
0:03:32 > 0:03:35- Are you really into dinosaurs?- Yeah.
0:03:35 > 0:03:37- What's your favourite dinosaur? - Brachiosaurus.
0:03:37 > 0:03:40Brachiosaurus.
0:03:40 > 0:03:42What's your team name?
0:03:44 > 0:03:46So, there you go, those are the teams.
0:03:46 > 0:03:48And this is the show with a need for speed,
0:03:48 > 0:03:50a craving for creativity,
0:03:50 > 0:03:54and above all, a demand for ingenious ideas and inventions.
0:03:54 > 0:03:57It's time for the warm-up!
0:03:57 > 0:04:00GUINEA PIG'S TEETH CHATTER
0:04:00 > 0:04:02Not that type of warm-up, GP.
0:04:02 > 0:04:04Bring me my questions!
0:04:06 > 0:04:09Thank you. Here we go then, teams. Are you ready?
0:04:09 > 0:04:12- ALL:- Yes.- Good, good. Hands on brains. Here we go.
0:04:12 > 0:04:13Take 4,
0:04:13 > 0:04:15times it by 4,
0:04:15 > 0:04:17then minus 4,
0:04:17 > 0:04:19then times by 4.
0:04:19 > 0:04:21Super Ecstatic Scientists!
0:04:21 > 0:04:2248.
0:04:22 > 0:04:24Is right! What a lot of fours.
0:04:24 > 0:04:26What word am I spelling backwards?
0:04:34 > 0:04:37Super Ecstatic Scientists!
0:04:37 > 0:04:39No! I'm afraid it's greenhouse.
0:04:39 > 0:04:41What is this sound?
0:04:41 > 0:04:44BRAYING
0:04:48 > 0:04:50Fantabulists.
0:04:50 > 0:04:51A donkey.
0:04:51 > 0:04:52Is the right answer!
0:04:52 > 0:04:55How many letters are there in the word ultimate?
0:04:55 > 0:04:57Super Ecstatic Scientists.
0:04:57 > 0:04:58- Eight.- Eight.
0:04:58 > 0:04:59Is right!
0:04:59 > 0:05:02Now, put yourselves in order of how far you can stick out your tongue,
0:05:02 > 0:05:05from the shortest this side to the longest that side.
0:05:05 > 0:05:08Go and then press your buzzers.
0:05:08 > 0:05:09Science Warriors!
0:05:09 > 0:05:11Let's have a look. What do we think?
0:05:11 > 0:05:14Yes! I think that's right. Well done, you Blues.
0:05:15 > 0:05:18Good job, Blues. But Yellows take the lead.
0:05:18 > 0:05:22Wow, what a fantastic round. And that was just the warm-up.
0:05:22 > 0:05:25Let's heat things up with the ignition round.
0:05:30 > 0:05:33We've got a good experiment to do now, haven't we,
0:05:33 > 0:05:34my good friend, Guinea...?
0:05:35 > 0:05:38Where is he? Guinea Pig! What are you doing over there?
0:05:38 > 0:05:41So, to get the ultimate brainy look, what you need to do is use this
0:05:41 > 0:05:43and then go around the inside of the eye...
0:05:43 > 0:05:47- Stop vlogging and come over here, GP.- Sorry, Dr Brain.- Come on!
0:05:47 > 0:05:50I was just doing some internet research on quantum entanglement.
0:05:50 > 0:05:52Oh, hurry up. Come on. Come on.
0:05:52 > 0:05:55So, teams, what do you think I've got here?
0:05:55 > 0:05:56- No idea.- A bottle.
0:05:56 > 0:05:58A bottle, that's right. What does this look like?
0:05:58 > 0:06:00- ALL:- A pump.- That's right, a pump,
0:06:00 > 0:06:04which is going to be activated by guinea power.
0:06:04 > 0:06:07And that's going to pump air all the way along this tube
0:06:07 > 0:06:11into this bottle, which contains just a little bit, can you see?
0:06:11 > 0:06:15Just a little bit of medical alcohol.
0:06:15 > 0:06:17So, we're going to place it in like this,
0:06:17 > 0:06:20seal it off and hold that there while Guinea Pig pumps away.
0:06:20 > 0:06:23And then, I'm going to remove the tube
0:06:23 > 0:06:26and I'm going to ask you what's going to happen.
0:06:26 > 0:06:27Your options are as follows.
0:06:27 > 0:06:32A, a thick cloud will form inside the bottle.
0:06:32 > 0:06:36B, the bottle will collapse in on itself.
0:06:36 > 0:06:40C, the bottle will omit a rather rude and loud raspberry noise.
0:06:40 > 0:06:42GUINEA PIG BLOWS RASPBERRY Yes, like that.
0:06:42 > 0:06:46Or D, something else.
0:06:46 > 0:06:49Something only you have thought of.
0:06:49 > 0:06:52Or, perhaps, you have thought of.
0:06:52 > 0:06:55You're thinking time starts now!
0:06:56 > 0:06:58THEY WHISPER
0:06:58 > 0:07:00Four options here.
0:07:03 > 0:07:04The air has to come out.
0:07:04 > 0:07:07The alcohol...
0:07:07 > 0:07:09- The cloud.- Yeah, I thought that.
0:07:09 > 0:07:12At first, I thought it was that one, but now I don't think it is.
0:07:12 > 0:07:14Have you got your answer?
0:07:14 > 0:07:16- If it's alcohol, then... - SIREN WAILS
0:07:16 > 0:07:19That's it. Thinking time is over.
0:07:19 > 0:07:23It's time to see your answers right now!
0:07:23 > 0:07:25Let's have a look.
0:07:25 > 0:07:28A, A and C.
0:07:28 > 0:07:31I've got to ask you, Blues, why C?
0:07:31 > 0:07:33Good question. We just kind of cancelled it out.
0:07:33 > 0:07:36We think that it's just going to sort of
0:07:36 > 0:07:38equalise the pressure, because
0:07:38 > 0:07:40it's just the medical alcohol, so,
0:07:40 > 0:07:42it's around air anyway,
0:07:42 > 0:07:44so, I don't see why that would create a reaction.
0:07:44 > 0:07:46I don't think it's going to collapse in because it's just
0:07:46 > 0:07:48- going to sort of equalise, I think. - Yeah, that is.
0:07:48 > 0:07:51Oh, I see, so you've eliminated those two and you've gone
0:07:51 > 0:07:54- for that one.- Yeah.- Yeah.- And also, because it might be the funniest.
0:07:54 > 0:07:56- Yeah, I hope it does happen. - Exactly.- Hopefully.- Yes, absolutely.
0:07:56 > 0:07:59So, you think it's going to make a very rude noise.
0:07:59 > 0:08:01- It's going to force out a kind of...noise.- Think so.
0:08:01 > 0:08:04Now, then, we have two As over here. I'm going to ask the Greens first.
0:08:04 > 0:08:06There's one reason why I didn't think it could be C,
0:08:06 > 0:08:09is because, usually it only makes a noise like that
0:08:09 > 0:08:12when there's, like, pressure and it's trying to get through it.
0:08:12 > 0:08:15But, that's quite a big hole, so it can just come through easily.
0:08:15 > 0:08:16- Oh, I see, right.- Yeah.
0:08:16 > 0:08:19And then, I don't think it's B.
0:08:19 > 0:08:22I don't really know why, I just don't think it is.
0:08:22 > 0:08:24- Not going to collapse. - And then, D, we couldn't think
0:08:24 > 0:08:26of anything, so, we sort of just went for A.
0:08:26 > 0:08:29- You've gone for A.- Yeah. - OK. Very interesting.
0:08:29 > 0:08:30Yellows, what's your thinking?
0:08:30 > 0:08:34Well, I think, cos I've done an experiment at home,
0:08:34 > 0:08:36if you get a tray, and you put ice on top of it,
0:08:36 > 0:08:40and you get hot water and you put the tray on top of the jug,
0:08:40 > 0:08:41a cloud forms inside.
0:08:41 > 0:08:44I think that's what's going to happen with the bottle.
0:08:44 > 0:08:46And that's a difference between the temperatures causes the cloud.
0:08:46 > 0:08:49Very interesting. Well, I wonder if they're going to be right.
0:08:49 > 0:08:52How are your muscles, GP? Let's have a feel. Oh, yes.
0:08:52 > 0:08:53They're like iron.
0:08:53 > 0:08:56Iron that's been melted down into a very soft fudge.
0:08:56 > 0:08:58THEY CHUCKLE
0:08:58 > 0:09:00Come on. Let's have a go. Activate.
0:09:00 > 0:09:02Now, I'm just placing the bung into the top of the bottle.
0:09:02 > 0:09:04Nice and strong like that. OK, GP, are you ready?
0:09:04 > 0:09:07Three, two, one, pump!
0:09:07 > 0:09:08Pump it up, pump it up!
0:09:08 > 0:09:11# Pump up the jam, pump it up... #
0:09:11 > 0:09:14Pumping away. The pressure going in.
0:09:14 > 0:09:16A few more, I think. There we go.
0:09:16 > 0:09:18Right, now, let's have a look, then, shall we?
0:09:18 > 0:09:20LOUD SNAP
0:09:20 > 0:09:22THEY GROAN
0:09:22 > 0:09:23Two things happened.
0:09:23 > 0:09:26One, it goes bang and scares the life out of everybody.
0:09:26 > 0:09:30And two, a cloud has formed!
0:09:30 > 0:09:31As the air is squeezed
0:09:31 > 0:09:32into the bottle,
0:09:32 > 0:09:34it gets warmer and the liquid
0:09:34 > 0:09:36starts to evaporate into a vapour.
0:09:36 > 0:09:37When the lid is taken off,
0:09:37 > 0:09:39the pressure is released,
0:09:39 > 0:09:41turning the vapour back into millions of droplets
0:09:41 > 0:09:44suspended in the bottle, giving a cloud.
0:09:44 > 0:09:47Now, here's an interesting thing. Let's give it another pump.
0:09:47 > 0:09:49So, look what happens here, look.
0:09:49 > 0:09:51When you pump it again,
0:09:51 > 0:09:52it all disappears.
0:09:52 > 0:09:54Oh, you see.
0:09:54 > 0:09:57And then it comes back again, which is very similar to the way
0:09:57 > 0:10:01that changes in air pressure create the clouds in the sky.
0:10:01 > 0:10:04So, that's 10 points for the Yellows and the Greens!
0:10:04 > 0:10:05Well done!
0:10:09 > 0:10:10Smoke signals.
0:10:10 > 0:10:12He-llo.
0:10:12 > 0:10:15It-is-time-for-the-next...
0:10:15 > 0:10:17round!
0:10:22 > 0:10:25Oh, look at that. I'm well fit, me. Fit as a fiddle.
0:10:25 > 0:10:29Poor old Guinea Pig isn't, though. He's absolutely exhausted.
0:10:29 > 0:10:32He was on his hamster wheel all morning going round and round
0:10:32 > 0:10:33and round and round, like that.
0:10:33 > 0:10:37So, he said, "Dr Brain, can I go for a nap, please?"
0:10:37 > 0:10:38So, I said, "Yes, fine, off you go."
0:10:38 > 0:10:40And, then, I suddenly remembered,
0:10:40 > 0:10:43I'd been using his bed to store all my balloons.
0:10:43 > 0:10:45Oh, no! On the bottom and on the top.
0:10:45 > 0:10:48So, I've asked my teams to come up with some clever contraptions
0:10:48 > 0:10:52and devious devices to help us to pop all the balloons
0:10:52 > 0:10:53as quickly as possible.
0:10:53 > 0:10:58I gave them each a budget of £30 million
0:10:58 > 0:11:00divided by a million,
0:11:00 > 0:11:03and two days to come up with their design.
0:11:03 > 0:11:06Teams must help GP sort out his spot for slumber
0:11:06 > 0:11:09and think of a way to help him burst as many of the balloons
0:11:09 > 0:11:11above and below him on his bed as possible.
0:11:11 > 0:11:13The plan that manages to burst the most balloons
0:11:13 > 0:11:17in the time provided, will earn a gigantic 10 points.
0:11:17 > 0:11:18Here he is.
0:11:18 > 0:11:24He's absolutely bursting with sleepiness, Mr Guinea Pig!
0:11:24 > 0:11:25THEY CHEER
0:11:25 > 0:11:27Shh! Don't wake him up.
0:11:27 > 0:11:29Hi, GP. HE YAWNS
0:11:29 > 0:11:33- You all right?- Yeah, I just can't wait to have my nap.
0:11:33 > 0:11:38Yes, yes, I'm sure it's going to be lovely. Off you go then.
0:11:38 > 0:11:40Oops! Don't tell him.
0:11:40 > 0:11:42I hope your plans are going to be good.
0:11:42 > 0:11:46Yellows, why does Guinea Pig look like he's got the O2 on his head?
0:11:46 > 0:11:50We were thinking that he could jump up and down,
0:11:50 > 0:11:53so he could get the balloons on the top.
0:11:53 > 0:11:56He's got the spikes on his feet to cover more surface area.
0:11:56 > 0:11:59Good scientific thinking. What about his knees and his elbows?
0:11:59 > 0:12:02- What's that there? - Well, he's accident-prone,
0:12:02 > 0:12:05so when he, like, falls over, the balloons will pop.
0:12:05 > 0:12:06Good thinking. And what's he holding?
0:12:06 > 0:12:09Sticks with spikes on the end, like spears.
0:12:09 > 0:12:11He's looking pretty sharp, isn't he?
0:12:11 > 0:12:12Pretty sharp!
0:12:14 > 0:12:17Marvellous stuff. What's your plan called?
0:12:17 > 0:12:20- ALL:- Spiky Sonic Suit.
0:12:20 > 0:12:24The Super Ecstatic Scientists have given GP two large poles
0:12:24 > 0:12:27with single spikes at either end for added reach.
0:12:27 > 0:12:31A pair of prickly shoes and, knowing he's forever falling over,
0:12:31 > 0:12:34they've also cunningly added spikes to his protective pads.
0:12:34 > 0:12:37Topping the plan is a helmet covered in sharp pencils,
0:12:37 > 0:12:39with so many elements for the Yellow's design,
0:12:39 > 0:12:41something's got to work, hasn't it? Hasn't it?!
0:12:42 > 0:12:46Three, two, one, go, GP!
0:12:53 > 0:12:55Fire works night, is it?
0:12:55 > 0:12:57- Oh, my God!- Keep jumping!
0:12:57 > 0:12:59Jump higher! Jump higher!
0:12:59 > 0:13:01Jump to the left!
0:13:01 > 0:13:03Walk over!
0:13:03 > 0:13:05Wow.
0:13:05 > 0:13:06Jump up and down!
0:13:08 > 0:13:11It sounds like a giant popcorn making machine.
0:13:11 > 0:13:13DR BRAIN LAUGHS
0:13:13 > 0:13:15Use your elbow pads!
0:13:15 > 0:13:16Yeah, use your elbow pads.
0:13:16 > 0:13:18Use your elbow pads. That's it.
0:13:18 > 0:13:20- You tell him. You tell him. - That's it!
0:13:20 > 0:13:23Oh, good work. Look at that.
0:13:24 > 0:13:26Keep on going! Keep on going!
0:13:26 > 0:13:28Nearly there. That's it. So many options.
0:13:28 > 0:13:30Get the other one! Get the other one!
0:13:30 > 0:13:32SIREN WAILS
0:13:32 > 0:13:34There we go! That's time up.
0:13:34 > 0:13:35That's time up!
0:13:35 > 0:13:38- How do you think your plan went there, Yellows?- Really good.
0:13:38 > 0:13:39- Really good.- Really good, wasn't it?
0:13:39 > 0:13:42He had so many options, he didn't know quite what to do.
0:13:42 > 0:13:44Guinea Pig, how are you feeling?
0:13:44 > 0:13:46I'm popped!
0:13:46 > 0:13:48Some perfect popping there.
0:13:48 > 0:13:49But what about those pencils?
0:13:49 > 0:13:51They made less of a mark on the task in hand
0:13:51 > 0:13:53and really just made marks on the balloons.
0:13:53 > 0:13:56It is the soft properties of graphite that make it
0:13:56 > 0:13:59so useful for writing with, as its layers of carbon atoms slide
0:13:59 > 0:14:01over each other with weak forces between them.
0:14:01 > 0:14:03It slips easily from pencil to paper,
0:14:03 > 0:14:06hence the need for regular sharpening.
0:14:06 > 0:14:09So, here we have the Blue plan.
0:14:09 > 0:14:12Why is Guinea Pig dressed up like Dot Cotton?
0:14:12 > 0:14:14We thought, you know, to help him get into character.
0:14:14 > 0:14:18Oh, nice. Nice touch. Yes, I like that. So, talk me through your plan.
0:14:18 > 0:14:20Well, we're hoping with the litter picker
0:14:20 > 0:14:23and the spikes on his feet, he can hold the balloons in place.
0:14:23 > 0:14:26Yeah, and then the Hoover is for the top.
0:14:26 > 0:14:28- There's a technique to this.- Yeah.
0:14:28 > 0:14:29- Oh, yes? - Yeah.- It's called the crazy.
0:14:29 > 0:14:31We tried it at home.
0:14:31 > 0:14:34It's actually my own brand of vacuum cleaner called an Oo-oo-ver.
0:14:34 > 0:14:36So, what's the name of your plan?
0:14:36 > 0:14:38- ALL:- The Balloonatron.
0:14:38 > 0:14:40The Balloonatron.
0:14:40 > 0:14:42Oh, I like that. How do you feel, GP?
0:14:42 > 0:14:45This is probably the most ridiculous idea we've ever had on
0:14:45 > 0:14:46Ultimate Brain, Dr Brain.
0:14:46 > 0:14:48No, it isn't.
0:14:48 > 0:14:51The Science Warriors' Balloonatron
0:14:51 > 0:14:52uses spikes on GP's feet
0:14:52 > 0:14:54with a litter picker to stabilise
0:14:54 > 0:14:56the balloons ready to be kicked.
0:14:56 > 0:14:59For the balloons above, they provided a vacuum cleaner
0:14:59 > 0:15:02and hose that they're hoping will have the suction power to pop.
0:15:02 > 0:15:05So, will they clean up or does this plan suck?
0:15:05 > 0:15:07It's time to find out!
0:15:07 > 0:15:11Three, two, one, go, Guinea Pig!
0:15:12 > 0:15:15Yes! It's working!
0:15:15 > 0:15:17Up high! Up high!
0:15:17 > 0:15:19Come on! Just keep kicking!
0:15:19 > 0:15:22Yeah, keep kicking!
0:15:22 > 0:15:24Come on! Come on! Come on!
0:15:24 > 0:15:27Ignore the top. That's not working. Just do the bottom.
0:15:27 > 0:15:29Yeah, just the bottom.
0:15:31 > 0:15:34It's working quite well, I think.
0:15:34 > 0:15:37Keep kicking it! Put some foot into it. Go on, man!
0:15:37 > 0:15:40He's doing a dance move. What are you doing?
0:15:40 > 0:15:42What are you doing?!
0:15:42 > 0:15:43Push the Hoover into the balloon.
0:15:43 > 0:15:46- No, push the little thing... - No, just keep kicking!
0:15:46 > 0:15:47Push it into the balloon!
0:15:47 > 0:15:49THEY ALL SHOUT AT ONCE
0:15:49 > 0:15:52- Litter picker up high.- Kick!
0:15:52 > 0:15:55- No!- Aim for the bottom! Aim for the bottom!- Just whack it!
0:15:55 > 0:15:56SIREN WAILS
0:15:56 > 0:16:00There we go. That's time up. That's time up!
0:16:00 > 0:16:01Sorry, Blues, but not a lot
0:16:01 > 0:16:03of cleaning up going on there.
0:16:03 > 0:16:08That oo-oo-oo-ver is o-o-o-over with nowhere near enough suction power.
0:16:08 > 0:16:11Now, here we are with the Green plan.
0:16:11 > 0:16:13It looks quite simple. What's it called?
0:16:13 > 0:16:14- ALL:- Pins And Needles.
0:16:14 > 0:16:17And what is the theory behind your plan?
0:16:17 > 0:16:19What Guinea Pig is going to do is he's going to try
0:16:19 > 0:16:21and pop the balloons at the top.
0:16:21 > 0:16:23And when he's bringing the poll back down,
0:16:23 > 0:16:25he's going to try and pop the balloons on the bottom.
0:16:25 > 0:16:27So, you want him to hold it upright, like that,
0:16:27 > 0:16:29and go up, down, up, down, up, down, like that.
0:16:29 > 0:16:31- Are you getting that, GP? - You know what?
0:16:31 > 0:16:33I wasn't too sure about this idea, so, I slept on it,
0:16:33 > 0:16:35but then I woke up with a funny feeling.
0:16:36 > 0:16:40The Fantabulists have created Pins And Needles,
0:16:40 > 0:16:44a gladiator-style weapon for GP to take into battle!
0:16:44 > 0:16:46Using two spheres at each end of this pugil stick,
0:16:46 > 0:16:49provides a large, curved surface area.
0:16:49 > 0:16:50So, when covered in spikes,
0:16:50 > 0:16:54allows them to be positioned at lots of different angles.
0:16:54 > 0:16:56It's cactus technology, hombre!
0:16:56 > 0:16:58The lightweight pole in this two-pronged attack
0:16:58 > 0:17:03provides easy manoeuvring to stab at balloons above and below in one go.
0:17:03 > 0:17:07Three, two, one, go, Guinea Pig!
0:17:07 > 0:17:10- ALL:- Yeah, yeah, yeah, yeah!
0:17:11 > 0:17:14- Keep going!- Just like that!
0:17:16 > 0:17:18Keep going!
0:17:18 > 0:17:19Faster! Faster!
0:17:24 > 0:17:26Faster!
0:17:26 > 0:17:27Come on! Do the top ones too!
0:17:27 > 0:17:30- Do the top ones!- On the top!- Yeah!
0:17:30 > 0:17:33Keep going! Come on, come on, come on!
0:17:33 > 0:17:36Keep going! Come on, two more.
0:17:36 > 0:17:38OK. Only a few seconds left.
0:17:38 > 0:17:39He's nearly done it!
0:17:39 > 0:17:42Get the last one!
0:17:42 > 0:17:43That's it!
0:17:45 > 0:17:47Oh, well, have a cup of tea or something.
0:17:47 > 0:17:50SIREN WAILS There it goes! Wow, Greens!
0:17:50 > 0:17:54So many small spikes stabbing at once was super.
0:17:54 > 0:17:56Pushing through the rubber material's
0:17:56 > 0:17:59spaghetti-like polymer strands for popping power!
0:17:59 > 0:18:04Well, teams, that was pop-tastically balloon-mungous.
0:18:04 > 0:18:05- Did you enjoy that? ALL:- Yes!
0:18:05 > 0:18:07We like popping balloons, don't we?
0:18:07 > 0:18:10I'm bursting with pride, et cetera.
0:18:10 > 0:18:15- So, then, Blues, didn't quite come off, did it?- No.
0:18:15 > 0:18:17CLASSICAL MUSIC PLAYS
0:18:22 > 0:18:25I'm afraid you only got 23 out of the 200 balloons.
0:18:25 > 0:18:28Not a great success, I'm afraid, so no points for you.
0:18:28 > 0:18:31Yellows, you did pretty well, didn't you, I thought?
0:18:31 > 0:18:33Head-banger!
0:18:33 > 0:18:36HEAVY ROCK MUSIC PLAYS
0:18:40 > 0:18:45Well, I can tell you, you got 119 out of 200.
0:18:45 > 0:18:46That's pretty good, isn't it?
0:18:46 > 0:18:47But, Greens...
0:18:48 > 0:18:51..there's not a balloon left in the world
0:18:51 > 0:18:52that you haven't popped!
0:18:52 > 0:18:55# 99 red balloons
0:18:55 > 0:18:57# Floating in the summer sky. #
0:18:58 > 0:19:02You should take it up as a job, balloon pop-pery! Amazing!
0:19:02 > 0:19:06You got all of them, and therefore, you get 10 points.
0:19:09 > 0:19:12And, Yellows, cos you did so well and you got over 50%,
0:19:12 > 0:19:14I'm going to give you 5 points!
0:19:25 > 0:19:27# Me and Guinea Pig we're getting ready for the party
0:19:27 > 0:19:30# The party is going to be so great and I just can't wait
0:19:30 > 0:19:31# It's going to be so fun
0:19:31 > 0:19:32# We've got loads of balloons
0:19:32 > 0:19:34# Oh, no, we haven't cos we just popped them all
0:19:34 > 0:19:36# Oh, no, what we gonna do? #
0:19:36 > 0:19:39Oh, I know, party blowers. Yes, that's what we'll do.
0:19:39 > 0:19:41So, here's how it's going to work.
0:19:41 > 0:19:44Each of our contestants has their very own party blower.
0:19:44 > 0:19:46When they hear the Guinea Pig squeal...
0:19:46 > 0:19:47SQUEALING
0:19:47 > 0:19:49..they're going to give it a toot.
0:19:49 > 0:19:51And the first party blower that reaches full-length
0:19:51 > 0:19:52is going to be the winner!
0:19:52 > 0:19:55- Are you ready, teams? ALL:- Yes.
0:19:55 > 0:19:57Here we go, then. Facing forward.
0:19:57 > 0:19:59Come on, Stephen.
0:19:59 > 0:20:00SQUEALING
0:20:02 > 0:20:04Ooh. Woohoo!
0:20:04 > 0:20:06Top blowing, one and all.
0:20:06 > 0:20:09But it's clearly between the Blues and the Yellows.
0:20:09 > 0:20:13In slow mo-tion.
0:20:15 > 0:20:18Well, blow me away.
0:20:18 > 0:20:20I'm certainly ready for a party after that.
0:20:22 > 0:20:24So, there we have slow motion confirmation of the fact
0:20:24 > 0:20:27that the Blues get 10 points.
0:20:27 > 0:20:28Well done, you Blues.
0:20:28 > 0:20:30Come on then. Time for the next round.
0:20:30 > 0:20:33THEY ALL BLOW ON PARTY POPPERS
0:20:33 > 0:20:36Blues back in the game, getting 10 points.
0:20:41 > 0:20:44So, Guinners, old bean, what do you know about pressure?
0:20:44 > 0:20:47I know a lot about pressure, Dr Brain, cos, you know,
0:20:47 > 0:20:49whenever we do the challenges, I feel that the success of it
0:20:49 > 0:20:52all rests on my shoulders and I feel a lot of pressure.
0:20:52 > 0:20:54# Under pressure. #
0:20:54 > 0:20:55Well, don't worry, GP,
0:20:55 > 0:20:58- because the pressure is all on the contestants with this one.- Phew!
0:20:58 > 0:21:01Now, what they have here is some measuring beakers
0:21:01 > 0:21:04and they have a hose, which, itself, has quite a low pressure.
0:21:04 > 0:21:07And they can use any of those objects there,
0:21:07 > 0:21:08or none of them if they want,
0:21:08 > 0:21:11to get the water from the hose into the beakers.
0:21:11 > 0:21:13They've got a sponge, a ruler, a water soaker,
0:21:13 > 0:21:15a little measuring beaker and some pipettes.
0:21:15 > 0:21:19And the one who gets the most water over into the beakers wins.
0:21:19 > 0:21:21The challenge being that the tap is very low pressure.
0:21:21 > 0:21:23Ooh, trippy.
0:21:23 > 0:21:25- Do you think you can do it, GP? - Yeah.
0:21:33 > 0:21:36Let's hope our teams are a little bit more inspired.
0:21:38 > 0:21:40Three, two, one, go!
0:21:43 > 0:21:46Right, so, we fill these up and then we all get one.
0:21:46 > 0:21:48No, that wouldn't do as well.
0:21:48 > 0:21:51- Could you, like, pour that over there?- So, we all need to get one.
0:21:51 > 0:21:52- Just go.- No, we all need to get one.
0:21:52 > 0:21:54Agree on something, Greens.
0:21:54 > 0:21:56OK. Where's the water?
0:22:00 > 0:22:02I don't know what I'm doing.
0:22:02 > 0:22:03Why is it not coming?!
0:22:03 > 0:22:04Going well, Dr Grace?
0:22:04 > 0:22:06Come on! Really?!
0:22:06 > 0:22:08Definitely using this.
0:22:08 > 0:22:10SHE GIGGLES
0:22:10 > 0:22:13Creative thinking from the Yellows.
0:22:13 > 0:22:14This is useless.
0:22:18 > 0:22:19No.
0:22:19 > 0:22:22Hoo-hoo! Well, at least they're having fun.
0:22:22 > 0:22:24- Stephen, you go and bring that over now.- Yeah, you take that.
0:22:24 > 0:22:26- Steady. - So, what, shall we soak the sponge?
0:22:26 > 0:22:29Yeah, just soak the sponge and then, like, rinse it out.
0:22:30 > 0:22:33You know you're allowed to put your hand over it.
0:22:33 > 0:22:36- SHE GIGGLES - Let me use this. Let me use this!
0:22:37 > 0:22:39I can't fill it! I can't fill it.
0:22:41 > 0:22:44- What?! - Laura, you've got the best one here.
0:22:44 > 0:22:47And, then, Rachel, go over and squeeze it out.
0:22:47 > 0:22:48I don't think this is much use.
0:22:48 > 0:22:50Dr Rebekah, taking the lead.
0:22:51 > 0:22:54- I can't! How does this work?- Wait.
0:22:54 > 0:22:56- Oh... - I don't know how to fill this up!
0:22:56 > 0:22:58Um... Put it under the hose?
0:23:03 > 0:23:07Teams who can work well under pressure will do well at this game.
0:23:07 > 0:23:09Well under pressure.
0:23:09 > 0:23:10Hold it a bit longer, Amelia.
0:23:13 > 0:23:15Whoops!
0:23:15 > 0:23:19- Maybe you could wrap it up and line it up?- Yeah, you go over it.
0:23:23 > 0:23:26- Are you feeling the pressure? - No, I'm not.- Definitely.
0:23:28 > 0:23:29You could, like, catch that at the end,
0:23:29 > 0:23:32so, then, you don't need to come running back.
0:23:32 > 0:23:33See, you could do that.
0:23:33 > 0:23:35Yes, or getting the ruler.
0:23:35 > 0:23:37Wait, Laura, come here!
0:23:37 > 0:23:38Fill that up.
0:23:38 > 0:23:39Not long left.
0:23:41 > 0:23:42Gotcha!
0:23:42 > 0:23:44- I'm filling up the same ones, guys. - 10 seconds!
0:23:46 > 0:23:48- See, you can do that.- Yeah.
0:23:50 > 0:23:52SIREN WAILS
0:23:52 > 0:23:54Time up! That's your time up.
0:23:56 > 0:24:00So, that was a funny old challenge, wasn't it? How did you find it?
0:24:00 > 0:24:02- It was quite hard.- Really hard. - Quite hard, wasn't it?
0:24:02 > 0:24:06Now, there was a clue which I gave to you all.
0:24:06 > 0:24:08Do you remember hearing these words?
0:24:08 > 0:24:10Teams that work well under pressure...
0:24:10 > 0:24:12ECHOES: Pressure, pressure, pressure...
0:24:12 > 0:24:13..will do well...
0:24:13 > 0:24:14ECHOES: Well, well, well...
0:24:14 > 0:24:16Are you feeling the pressure?
0:24:16 > 0:24:18ECHOES: Pressure, pressure, pressure...
0:24:18 > 0:24:22- Do you remember hearing me say that? ALL:- Yeah.- Well, that was the clue.
0:24:22 > 0:24:24Now, Dr Marriott of the Yellows is going to help me
0:24:24 > 0:24:27to demonstrate how you should have done it.
0:24:27 > 0:24:29What you're going to do, Dr Marriott,
0:24:29 > 0:24:31is you're going to place your thumb or finger of your choosing,
0:24:31 > 0:24:35over half of the end of the hose for me.
0:24:35 > 0:24:37Can you do that?
0:24:37 > 0:24:38That has increased the pressure.
0:24:38 > 0:24:41And if you try and fire it at the cups...
0:24:41 > 0:24:43There we go! You see?
0:24:43 > 0:24:45What's happened is you've increased
0:24:45 > 0:24:46the pressure of the water
0:24:46 > 0:24:50by decreasing the area through which it can go, you see.
0:24:52 > 0:24:54That's how you should have done it. Lateral thinking.
0:24:54 > 0:24:55Nobody thought of it.
0:24:55 > 0:24:59But I can reveal that the team that got the most water
0:24:59 > 0:25:00into the cups was...
