0:00:09 > 0:00:13Can Guinea Pig catch more than a cold in this downpour?
0:00:13 > 0:00:15And can this week's contestants tie themselves in knots
0:00:15 > 0:00:18whilst blindfolded?
0:00:18 > 0:00:21It's packed full of fabulous fun super duper science,
0:00:21 > 0:00:22what's not to like?
0:00:22 > 0:00:25It's...
0:00:32 > 0:00:36Hi there, hi there. My name is Dr Brain.
0:00:36 > 0:00:38Join me on a scientific quest
0:00:38 > 0:00:41to find minds of crackling cleverness,
0:00:41 > 0:00:45gargantuan genius and dastardly deduction.
0:00:47 > 0:00:49Bwwwrrpp!
0:00:49 > 0:00:52Oh, sorry, garlic for lunch.
0:00:52 > 0:00:56This is Ultimate Brain!
0:00:57 > 0:00:59Let's meet the magnificent minds
0:00:59 > 0:01:01hoping to excel in today's experiments.
0:01:01 > 0:01:04It's the city slickers in green from London town.
0:01:08 > 0:01:12Team Yellow marching in together from Leeds, Leeds, Leeds!
0:01:12 > 0:01:13It's...
0:01:16 > 0:01:19And in blue, a terrifically scientific team
0:01:19 > 0:01:21from CBBC's Friday Download,
0:01:21 > 0:01:22it's good old...
0:01:28 > 0:01:33Now, you will need to be super duper smart to succeed today.
0:01:33 > 0:01:36Any average geniuses might as well go home right now. Do we have any?
0:01:36 > 0:01:38Do we have any? No? Excellent.
0:01:38 > 0:01:42Now, you will be playing for honour, but more importantly,
0:01:42 > 0:01:45if you succeed, you'll make an old monkey proud.
0:01:45 > 0:01:47HE CHUCKLES
0:01:47 > 0:01:50- The Green Team! How are you, Greens?- We are cool.- We are cool.
0:01:50 > 0:01:55Good, good. Dr Abado, what would you like to be when you leave school?
0:01:55 > 0:01:59I like sketching things in real life and painting them.
0:01:59 > 0:02:01- A good painter, are you?- Yeah.
0:02:01 > 0:02:03Well, to be honest, right,
0:02:03 > 0:02:05my roof could do with a little bit of painting, and the ceiling.
0:02:05 > 0:02:07And a few of the doors around the back.
0:02:07 > 0:02:09Do you think if I got you a nice roller and some paint,
0:02:09 > 0:02:12- you could do that for me? - OK.- Go on, have a go.
0:02:12 > 0:02:15- Now, what is your team name? - Team Hydra.
0:02:15 > 0:02:17Team Hydra. I like that.
0:02:17 > 0:02:18There we are, that is the Greens!
0:02:18 > 0:02:20CHEERING
0:02:20 > 0:02:23- Hi, folks. Now, then, Dr Daniel... - Hi.
0:02:23 > 0:02:25What do you want to be when you leave school?
0:02:25 > 0:02:26- A lawyer.- A lawyer?- Yeah.
0:02:26 > 0:02:29I could do with a lawyer, mate, I tell you.
0:02:29 > 0:02:32Now, what is it particularly about law that attracts you?
0:02:32 > 0:02:34- I just like arguing! - Oh, you like arguing?- Yeah.
0:02:34 > 0:02:36Well, that could be fun!
0:02:36 > 0:02:39- Do you argue with your team much? - Not really, we are kind of friends.
0:02:39 > 0:02:42- Are you all friends?- Yeah.- That is good. What is your team name?
0:02:42 > 0:02:43The Ultimate Foxes.
0:02:43 > 0:02:46The Ultimate Foxes. There they are, the Yellows!
0:02:46 > 0:02:48CHEERING
0:02:48 > 0:02:50Finally, the Friday Freeloaders.
0:02:50 > 0:02:51I mean the Fee Low Fooloaders...
0:02:51 > 0:02:54I mean, the Far Low... Friday Downloaders!
0:02:54 > 0:02:58- Here they are. How you doing?- Great. - Dr Molly...- Hello.
0:02:58 > 0:02:59- Nice to meet you.- You, too.
0:02:59 > 0:03:02Now, I'm really sorry that you got beaten by a singing dog
0:03:02 > 0:03:04called Pudsey on Britain's Got Talent.
0:03:04 > 0:03:07Well, he was not a singing dog, he was actually a dancing dog.
0:03:07 > 0:03:11- A bit different.- You couldn't even dance as well as a dog?! Ha-ha-ha!
0:03:12 > 0:03:16- Just kidding you! Dr Leondre, where are you from?- I am from Wales.
0:03:16 > 0:03:19Lovely Welsh Wales. And do you speak any languages?
0:03:19 > 0:03:23- Actually, my family is Italian. - Do you speak Italian?- Yeah.
0:03:23 > 0:03:25- It is a bit Welshy.- Come on, then, give us a bit.
0:03:25 > 0:03:27- WELSH ACCENT:- Ciao, bella.
0:03:27 > 0:03:31Oh! Ciao, bella, lovely. That's lovely, ciao, bella. I like that.
0:03:31 > 0:03:36Very, very nice. Good luck, Blues. What is your team name?
0:03:36 > 0:03:38Well, obviously, because we are Bars And Melody,
0:03:38 > 0:03:39and her name is Molly,
0:03:39 > 0:03:42we've decided to call it Bars And Molly-dy.
0:03:42 > 0:03:45# Oh, Bars And Molly-dy... # I love it.
0:03:45 > 0:03:47Good to meet you, Blues.
0:03:47 > 0:03:49It's time for round one.
0:03:56 > 0:03:59Here we go, then, teams, with our first round.
0:03:59 > 0:04:05The round we call the ignition round. Mm, Marshmallows.
0:04:05 > 0:04:06Oh, sorry.
0:04:06 > 0:04:11What will happen if I place a little marshmallow person -
0:04:11 > 0:04:14like my friend Marshmallow Dave, in there -
0:04:14 > 0:04:17- into a vacuum? - HOOVER STARTS UP
0:04:17 > 0:04:20I don't mean the kind of vacuum cleans up your bedroom carpet,
0:04:20 > 0:04:23not that kind of vacuum, no, I mean the kind of vacuum
0:04:23 > 0:04:26where you remove almost all of the air from a space...
0:04:26 > 0:04:31- ECHOES:- ..space... ..space...
0:04:31 > 0:04:34What is going to happen, folks? Look at the confusion on their faces.
0:04:34 > 0:04:36Will Marshmallow Dave in there...
0:04:48 > 0:04:49Something may be that you have
0:04:49 > 0:04:51thought of, of your own creation,
0:04:51 > 0:04:53that maybe my monkey brain
0:04:53 > 0:04:56hasn't thought of? Ooh!
0:04:56 > 0:05:00Now then, my brainy beauties, it is time to decide amongst yourselves.
0:05:00 > 0:05:03You have a little think. All right? Your time starts... Now!
0:05:05 > 0:05:06TEAMS WHISPER
0:05:06 > 0:05:09So, four choices here.
0:05:09 > 0:05:13What fate awaits Marshmallow Dave in the vacuum?
0:05:13 > 0:05:16Certificate 15 at cinemas now.
0:05:16 > 0:05:18Have you thought of your answer?
0:05:18 > 0:05:19KLAXON BLARES
0:05:19 > 0:05:24OK, OK, that is it. Time is up. You're thinking time is done.
0:05:24 > 0:05:28It's time to reveal your answers... now!
0:05:28 > 0:05:29Let's have a look.
0:05:29 > 0:05:31Ooh, we have two As and a B.
0:05:31 > 0:05:34Very good exam results, that would be, wouldn't it?
0:05:34 > 0:05:36So, now then.
0:05:36 > 0:05:38Let's start with the Greens. You have gone for A.
0:05:38 > 0:05:43We think it is like, say, for example, a balloon,
0:05:43 > 0:05:46you would suck some air out of it, it would become a smaller balloon.
0:05:46 > 0:05:49Same thing with the marshmallow. You suck air out of it, it's...
0:05:49 > 0:05:53So you think the answer is A, it is going to shrink.
0:05:53 > 0:05:55Now, Yellows, you have the same answer.
0:05:55 > 0:05:57- Is your logic the same or is it different?- Yes, similar.
0:05:57 > 0:06:00Because we think it is air that makes the marshmallow puffy,
0:06:00 > 0:06:04- so if we take that out, it will shrink.- Oh, I see. Of course, yes.
0:06:04 > 0:06:08Cos there's quite a lot of air in Marshmallow Dave, isn't there?
0:06:08 > 0:06:10So, now, Blues?
0:06:10 > 0:06:13Well, we went for B, because you said about space,
0:06:13 > 0:06:15and we were thinking, float...
0:06:15 > 0:06:18When you remove the air, because there is no air
0:06:18 > 0:06:19and no oxygen in space,
0:06:19 > 0:06:21we didn't think it would get bigger or smaller.
0:06:21 > 0:06:23I just thought it would look cool as well, if it floats!
0:06:23 > 0:06:25That's true, it would, wouldn't it?
0:06:25 > 0:06:28- BEEPING - 'Floating through space...'
0:06:28 > 0:06:30That would be fun, wouldn't it?
0:06:30 > 0:06:33Well, let's see, have your mighty minds mastered this conundrum,
0:06:33 > 0:06:36or have you messed it right up like a bunch of melting marshmallows?
0:06:36 > 0:06:41- Are you ready?- Yes!- Three, two, one! Take it away, Dave!
0:06:41 > 0:06:42What is he going to do?
0:06:42 > 0:06:44What are you doing, Dave?
0:06:44 > 0:06:47Oh, what is going on...? Can you see?
0:06:47 > 0:06:49Oh, look!
0:06:49 > 0:06:51He is growing, he is growing,
0:06:51 > 0:06:53he is slightly falling over as well...
0:06:54 > 0:06:58But he is basically expanding,
0:06:58 > 0:06:59he is growing...
0:06:59 > 0:07:02Now, look at this.
0:07:02 > 0:07:05Watch this. You'll like this, this is fun. Here we go, Dave, ready?
0:07:10 > 0:07:14- Oh, look at that! Pretty cool, right?- I was not expecting that.
0:07:14 > 0:07:17You weren't expecting that, were you? Nobody was.
0:07:17 > 0:07:19Clearly, because you got the wrong answer! Ha-ha!
0:07:19 > 0:07:22Lovely fluffy marshmallows are puffed full of air
0:07:22 > 0:07:24trapped inside them.
0:07:24 > 0:07:26Now, ordinarily, this trapped air is pushing out
0:07:26 > 0:07:28against the air in the atmosphere
0:07:28 > 0:07:31which in turn is pushing back and everything is balanced.
0:07:31 > 0:07:34But when the vacuum removes the air from around the marshmallows,
0:07:34 > 0:07:36the air inside has nothing to push against,
0:07:36 > 0:07:38causing them to expand and get bigger.
0:07:38 > 0:07:41Then the marshmallows shrink when the vacuum seal is broken,
0:07:41 > 0:07:43as the air rushes back inside.
0:07:44 > 0:07:46The amazing answer was C.
0:07:46 > 0:07:50Which means, unfortunately, no points for anybody. Ha-ha!
0:07:50 > 0:07:52Time for the next round.
0:07:56 > 0:07:57The creative challenge.
0:07:57 > 0:08:02OK, brainboxes, it's time to get your think on. Creative style-y...
0:08:02 > 0:08:06Times are hard and I cannot afford to fix the holes in the studio roof.
0:08:06 > 0:08:08Should really come out of the studio budget,
0:08:08 > 0:08:12but then I wouldn't be able to afford my daily beauty routine.
0:08:12 > 0:08:15I have the same beautician as Cara Delevingne.
0:08:15 > 0:08:17So, when a storm comes, you see,
0:08:17 > 0:08:21we need to mop the floor to stop the studio from flooding.
0:08:21 > 0:08:25It is hard work, I can tell you. So that is where you come in.
0:08:25 > 0:08:28You see, our teams were given two days
0:08:28 > 0:08:31and a budget of £50
0:08:31 > 0:08:33to design their challenge.
0:08:33 > 0:08:36The holes in the studio ceiling are letting in water.
0:08:36 > 0:08:38The teams must create some headwear for GP
0:08:38 > 0:08:41that allows him to collect as much of that rainwater as possible
0:08:41 > 0:08:44while keeping his hands free to mop the studio floor.
0:08:44 > 0:08:47And hopefully, stop him getting soaked. Like this! Ha-ha!
0:08:47 > 0:08:48Teams need to think of an efficient,
0:08:48 > 0:08:51stable way of collecting water without spillage.
0:08:51 > 0:08:54When GP has finished, he will pour the water into a measuring tank.
0:08:54 > 0:08:55Whoever collect the most wins.
0:08:55 > 0:08:57Sounds easy, doesn't it?
0:08:57 > 0:08:59No, nothing is easy on this show.
0:08:59 > 0:09:02And here, determined to selflessly stride forward
0:09:02 > 0:09:08in the name of awesome science, a man without fear,
0:09:08 > 0:09:10a man without nerves,
0:09:10 > 0:09:12a man we call...
0:09:12 > 0:09:14Guinea Pig!
0:09:14 > 0:09:16APPLAUSE AND CHEERING
0:09:18 > 0:09:22- Sorry, just playing Super Guinea Pig Brothers. Hi.- Ha-ha, hi there, GP.
0:09:22 > 0:09:27- Confident?- Confident that I'm going to get very cold and very wet!
0:09:27 > 0:09:31- This outfit is completely waterproof.- Is it?
0:09:31 > 0:09:34Of course, 100%.
0:09:34 > 0:09:3540%, tops!
0:09:35 > 0:09:38Let's see what our teams have come up with.
0:09:38 > 0:09:42And first off, it is Team Hydra. So, what is the name of your plan?
0:09:42 > 0:09:45Operation Hydra-phobic.
0:09:45 > 0:09:47That is a good science name, I like that.
0:09:48 > 0:09:51Team Hydra have gone for a large surface area for water collection
0:09:51 > 0:09:56with drainage pipes and bottles placed evenly around GP.
0:09:56 > 0:10:01Hopefully, our hero can mop without spilling a drop.
0:10:01 > 0:10:06Guinea Pig, you have 60 seconds. In three, two, one!
0:10:06 > 0:10:08- Go, Guinea Pig! - KLAXON
0:10:08 > 0:10:12- You can encourage him, egg him on. - Go on, Guinea Pig!- Go on, Guinea Pig.
0:10:12 > 0:10:15Yes, there's definitely some water going in there.
0:10:15 > 0:10:18Oh, look at that, it is collecting water nicely.
0:10:18 > 0:10:22But the lack of stability is causing lots of spillage.
0:10:22 > 0:10:25Meaning more water on the studio floor for poor old GP to mop
0:10:25 > 0:10:29and less in the drainage pipes and collection bottles.
0:10:29 > 0:10:31Oh, there is a bit of splottage there.
0:10:31 > 0:10:34Splottage - a science word.
0:10:34 > 0:10:36Tilt it back, tilt your head back, GP.
0:10:36 > 0:10:38That's better.
0:10:38 > 0:10:39That's it.
0:10:39 > 0:10:40KLAXON BLARES
0:10:40 > 0:10:42And that's time up. Time up!
0:10:42 > 0:10:46You need to empty the water into the container now,
0:10:46 > 0:10:48to see how much there is.
0:10:48 > 0:10:51Is there any left in the bucket on your head as well, GP,
0:10:51 > 0:10:53that you could splosh in, do you think?
0:10:53 > 0:10:55Yes, there is a good bit there, you see.
0:10:55 > 0:10:57That was good thinking. Well done.
0:10:57 > 0:10:59They don't call me Dr Brain for nothing! Ha-ha!
0:10:59 > 0:11:03- How do you feel about that? Are you happy with it?- I'm OK.- Yeah?
0:11:03 > 0:11:04You all right?
0:11:04 > 0:11:07Your plan was quite good and don't forget it was Guinea Pig doing it.
0:11:07 > 0:11:10I think you've done pretty well there. But...
0:11:10 > 0:11:13who can beat you? Let's find out with the next plan,
0:11:13 > 0:11:16the plan of the Blue Friday Downloaders.
0:11:16 > 0:11:19Now, then, you Blues? What has he got on his head?
0:11:19 > 0:11:21Well, he has a bunch of sponges on his head.
0:11:21 > 0:11:23We thought it would be a really good idea
0:11:23 > 0:11:27- because sponges are made for clearing up water.- That is true.
0:11:27 > 0:11:29We thought if the rain is falling on them,
0:11:29 > 0:11:32it should suck up as much water as possible.
0:11:32 > 0:11:36Team Bars And Molly-dy have gone for a sponges super-soaker-upper idea.
0:11:36 > 0:11:40They hope the holes in the sponges will simply soak up the rainwater
0:11:40 > 0:11:44falling onto GP's head, leaving his hands free for some serious moppage.
0:11:44 > 0:11:47We are going to get to the top. You see that top line there?
0:11:47 > 0:11:50- We are going to get to there. - What is your plan named?
0:11:50 > 0:11:54- It is called the Sponginator 3000. - Sponginator 3000.
0:11:54 > 0:11:57Available in all stores from Christmas. Now then, here we go, GP.
0:11:57 > 0:12:00Get yourself ready, son. We are going to go for this.
0:12:00 > 0:12:02Looks like I'm going to have to soak this up.
0:12:02 > 0:12:04DING
0:12:10 > 0:12:13So, you have 60 seconds, Guinea Pig.
0:12:13 > 0:12:16In three, two, one!
0:12:16 > 0:12:19- Go, Guinea Pig! - KLAXON BLARES
0:12:19 > 0:12:21Here comes the rain, here it comes.
0:12:21 > 0:12:25It's raining, it's pouring, the old man snoring.
0:12:25 > 0:12:29- This isn't working.- You can chat. Tell him what to do.
0:12:29 > 0:12:31- Give him some encouragement. - Tip your head back!
0:12:31 > 0:12:33Tip your head back!
0:12:33 > 0:12:37- Keep it straight.- Right back! - It's working. It is working.
0:12:37 > 0:12:39Difficult to tell, isn't it?
0:12:40 > 0:12:44Well, it certainly looks impressive, and rather fashionable,
0:12:44 > 0:12:46but the sponges just aren't a very efficient way of collecting
0:12:46 > 0:12:48tiny drops of water.
0:12:48 > 0:12:51Look, it is bouncing off the surface! Oh...
0:12:53 > 0:12:54Water is quite heavy, you see.
0:12:54 > 0:12:55Stay strong!
0:12:55 > 0:12:59- Stay strong!- Stay wet. - Five seconds to go.
0:12:59 > 0:13:01KLAXON BLARES
0:13:01 > 0:13:04That's it. Time is up! Time is up.
0:13:04 > 0:13:09We are going to find out how much water was in those sponges.
0:13:09 > 0:13:11There is quite a bit there. There are a lot of sponges.
0:13:11 > 0:13:14- How do you think you've done? - I think we've done OK.
0:13:14 > 0:13:18Yeah, I think we've done well. I don't think we've quite won.
0:13:18 > 0:13:20It was a good idea, he didn't get too wet.
0:13:20 > 0:13:23We didn't get quite to the top line, though.
0:13:23 > 0:13:25No, but you've done pretty well.
0:13:25 > 0:13:27And there is only one way to find out,
0:13:27 > 0:13:28because there's another team to go.
0:13:28 > 0:13:31Let's see what their plan is.
0:13:31 > 0:13:34Now, you might be wondering why I'm looking at Guinea Pig
0:13:34 > 0:13:36as if he looks very, very stupid.
0:13:36 > 0:13:38The answer is, because he does!
0:13:38 > 0:13:41Yellows, what have you done to him? What is he wearing?
0:13:41 > 0:13:43We designed it to be a hoop.
0:13:43 > 0:13:45The water would fall through the bin bag
0:13:45 > 0:13:49and there are rope and string supports to keep it upright.
0:13:49 > 0:13:52The Ultimate Foxes have gone for a large surface area of collection
0:13:52 > 0:13:54with a hula hoop frame for added stability
0:13:54 > 0:13:58and one large drainage pipe to a collection system on GP's back.
0:13:58 > 0:14:01They're hoping he can mop the floor and collect the rain with ease,
0:14:01 > 0:14:03whilst looking like a weird alien. Fingers crossed!
0:14:03 > 0:14:05What's the name of your plan?
0:14:05 > 0:14:06ALL: Hula-Hoop Mania.
0:14:06 > 0:14:09Hula-Hoop Mania! Shall we see it in action?
0:14:09 > 0:14:12- ALL: Yeah!- Let's do it. You have 60 seconds, Guinea Pig,
0:14:12 > 0:14:15starting three...two...one...
0:14:15 > 0:14:17- NOW! - KLAXON BLARES
0:14:17 > 0:14:19Here comes the rain again.
0:14:19 > 0:14:20That's a song, isn't it?
0:14:20 > 0:14:22SHOUTS OF ENCOURAGEMENT
0:14:22 > 0:14:24I can see definitely some going in.
0:14:24 > 0:14:26Is it going into the bucket, though?
0:14:26 > 0:14:29- That's it, you tell him, you tell him.- Forward!
0:14:29 > 0:14:31CONTESTANTS SHOUT INSTRUCTIONS
0:14:31 > 0:14:33Yes, yes, that's right,
0:14:33 > 0:14:37- you've got to direct him into the flow, haven't you?- Stay there!
0:14:37 > 0:14:40- It's holding up all right, though.- Not really!
0:14:40 > 0:14:42It looks like it's still together.
0:14:44 > 0:14:46- Come on!- There's definitely some water going in there.
0:14:46 > 0:14:49- GUINEA PIG:- I feel like I'm at the Mardi Gras during the monsoon.
0:14:51 > 0:14:54Oh, dear, the large drainage system is simply too heavy.
0:14:54 > 0:14:56Even with the hula-hoop frame to support it,
0:14:56 > 0:14:58it's gone all droopy in the rain.
0:14:58 > 0:15:00A bit like GP.
0:15:00 > 0:15:02But will it be enough to beat the other teams?
0:15:02 > 0:15:04CONTESTANTS: Stay there, stay there!
0:15:04 > 0:15:05Come on, keep strong!
0:15:05 > 0:15:08Go back a bit, cos there's more powerful water.
0:15:08 > 0:15:11- Two...one...and that's time up! - KLAXON BLARES
0:15:11 > 0:15:13Stop, Guinea Pig, stop, stop, stop.
0:15:13 > 0:15:16Right, hasn't spilt any yet, that's all right.
0:15:16 > 0:15:18Now he's got to try and lift that round.
0:15:18 > 0:15:20Quietly confident about this.
0:15:21 > 0:15:23That looks like quite a good amount to me.
0:15:23 > 0:15:25Are you pleased?
0:15:25 > 0:15:27It could have gone better.
0:15:27 > 0:15:29It could have gone better, but that's science, isn't it?
0:15:29 > 0:15:31- That's experiments for you. - ALL: Yeah.
0:15:31 > 0:15:34Sometimes they go right, sometimes they go wrong.
0:15:34 > 0:15:37Team Hydra and the Ultimate Foxes both went for designs
0:15:37 > 0:15:40with a large surface area to collect lots of water,
0:15:40 > 0:15:44but they lacked stability, meaning there was lots of spillage.
0:15:44 > 0:15:48Bars And Molly-dy went for an altogether more spongy approach,
0:15:48 > 0:15:49but was it more effective?
0:15:49 > 0:15:52And who has mopped up the points?
0:15:52 > 0:15:54In third place...
0:15:54 > 0:15:57- DRUMROLL - ..we have the Blues!
0:15:57 > 0:16:01- THEY CHEER - There we see, with 365ml.
0:16:01 > 0:16:04- Where do I collect my medal? - Well done, there, Blues.
0:16:04 > 0:16:07But who are in second and first places?
0:16:07 > 0:16:11Well, I can tell you it's very, very, very close.
0:16:11 > 0:16:14In second place, it's...
0:16:14 > 0:16:18the Greens with 525ml
0:16:18 > 0:16:25and in first, it's the Yellows with 540ml! Well done, Yellows!
0:16:25 > 0:16:27Marvellous work, there. You see, very, very close.
0:16:27 > 0:16:30- How are you feeling? Feeling awesome?- Yeah!- Good.
0:16:30 > 0:16:34So you get ten points for that and for your commendable inventions,
0:16:34 > 0:16:38the Blues and the Greens, I'm going to give you both five valour points.
0:16:38 > 0:16:40Well done, teams!
0:16:40 > 0:16:43CHEERING AND APPLAUSE
0:16:48 > 0:16:52This next brain-busting round is all about quick reactions!
0:16:52 > 0:16:54- Pew! Pow! Fizz! - GUN FIRES, BULLETS RICOCHET
0:16:54 > 0:16:57Judging who reacts the quickest is beyond even my many, many powers,
0:16:57 > 0:17:00which happen to include super flight,
0:17:00 > 0:17:04invisibility and the ability to tie shoelaces with beams from my eyes.
0:17:04 > 0:17:06ZAP!
0:17:06 > 0:17:10Ha-ha-ha! But who will have the fastest reactions from our teams?
0:17:10 > 0:17:14A simple challenge, this one, but with the lightning-quick contenders,
0:17:14 > 0:17:19we're going to need a very special piece of equipment to help us. Yes!
0:17:19 > 0:17:21It's time to bring out...
0:17:21 > 0:17:24- SPEECH SLOWS:- ..the Slowmonizer.
0:17:24 > 0:17:27Yes, this super-cool camera records in...
0:17:27 > 0:17:31super very slow motion...
0:17:31 > 0:17:34so that I can accurately see who the winner is!
0:17:34 > 0:17:38Which brings us to the greatest long-lost Olympic event -
0:17:38 > 0:17:39blink and you'll miss it!
0:17:39 > 0:17:41No, you really might, actually.
0:17:41 > 0:17:43It's the one-metre sprint.
0:17:43 > 0:17:45- CROWD ROARS - Ho-ho-ho-ho!
0:17:45 > 0:17:47Here they are, the teams now, and finally,
0:17:47 > 0:17:50all that training that you may or may not have done
0:17:50 > 0:17:53over the last few minutes is about to pay off.
0:17:53 > 0:17:58Take to your marks, please, in the classic Olympic sprint pose.
0:17:58 > 0:18:01Now, when you hear this week's random sound of Dr Brain...
0:18:01 > 0:18:03- Pew! - BULLET RICOCHETS
0:18:03 > 0:18:04..the race begins.
0:18:04 > 0:18:06The winner is the first over the finish line,
0:18:06 > 0:18:09so let your minds absorb this epic sporting moment
0:18:09 > 0:18:12and your sweatbands absorb, well, some sweat, hopefully.
0:18:14 > 0:18:16ROUSING MUSIC PLAYS
0:18:19 > 0:18:21Ready?
0:18:21 > 0:18:23HEARTBEATS
0:18:26 > 0:18:28- Pew! - BULLET RICOCHETS
0:18:28 > 0:18:29And they're off! And it's over! What a race!
0:18:29 > 0:18:31The crowd would have been on their feet,
0:18:31 > 0:18:34had they had time to stand up, and if there was a crowd.
0:18:34 > 0:18:35Incredible stuff!
0:18:35 > 0:18:36- Pew! - BULLET RICOCHETS
0:18:43 > 0:18:45There's only one way to be sure.
0:18:45 > 0:18:47It's the greatest machine ever invented.
0:18:47 > 0:18:49Crank up the Slowmonizer!
0:19:01 > 0:19:03- It's Green!- Yeah! HE CHEERS
0:19:05 > 0:19:08Oh, look at that celebration, fantastic work there!
0:19:08 > 0:19:11That's ten points for you there, Greens.
0:19:18 > 0:19:21It's time for our teams to re-engage their brains.
0:19:21 > 0:19:23Yes, it's the inspiration challenge!
0:19:23 > 0:19:27Now, what did the great escape artist Houdini say to his mum
0:19:27 > 0:19:29when she phoned him in the middle of his act?
0:19:29 > 0:19:31- PHONE RINGS - "I can't talk now, Mum,
0:19:31 > 0:19:32"I'm a bit tied up!"
0:19:32 > 0:19:36- BA-DUM-TISH! - A bit tied up, you see!
0:19:36 > 0:19:38WIND HOWLS, THUNDER CRACKS
0:19:42 > 0:19:43Oh, forget it.
0:19:43 > 0:19:47We can all tie a knot in a rope, right, yeah? Everybody can do that.
0:19:47 > 0:19:48Oh, yeah, really.
0:19:48 > 0:19:51But what if it's a giant rope
0:19:51 > 0:19:55and all three people are holding it with both hands
0:19:55 > 0:19:57and none of you can let go?
0:19:57 > 0:20:00Each team have got a large rope in their team colour
0:20:00 > 0:20:04and they must all hold it with both hands.
0:20:04 > 0:20:07And two team members are blindfolded.
0:20:07 > 0:20:09Yes, blindfolded,
0:20:09 > 0:20:12so the third team member must code the knot-tying process
0:20:12 > 0:20:14by giving clear instructions
0:20:14 > 0:20:17to the blindfolded members of the team, you see?
0:20:17 > 0:20:21Now, the first team to successfully make a knot, wins!
0:20:21 > 0:20:22OK, teams?
0:20:22 > 0:20:26You have three minutes to think up your method of knot tying
0:20:26 > 0:20:28and your time starts...
0:20:28 > 0:20:30- now! - KLAXON BLARES
0:20:30 > 0:20:33So imagine that's the rope there. You go through here...
0:20:33 > 0:20:35creating a loop there.
0:20:35 > 0:20:37- Over, and then... - THEY WHISPER
0:20:37 > 0:20:39..then go under.
0:20:39 > 0:20:41- No, you go under!- I go under, OK.
0:20:41 > 0:20:44I've got to feed it through there and get through here.
0:20:46 > 0:20:49- Over, and then I go...- In.
0:20:49 > 0:20:52Like that, and then you come in, you come in.
0:20:52 > 0:20:56THEY CONFER
0:20:56 > 0:20:58- We lower the rope...- And then pull.
0:20:58 > 0:20:59KLAXON BLARES
0:20:59 > 0:21:01Right...
0:21:01 > 0:21:03if you've not got your knot designed,
0:21:03 > 0:21:05you're not going to get another shot of the knot,
0:21:05 > 0:21:06really, you're not. Ha-ha-ha!
0:21:06 > 0:21:09Right, first the Yellow team, tie your knot.
0:21:09 > 0:21:12The rest of you must wear your blindfolds
0:21:12 > 0:21:14and your ear defenders, OK?
0:21:14 > 0:21:16So you can't take a peak
0:21:16 > 0:21:19or hear how the team challenge is going, alrighty?
0:21:19 > 0:21:22So it's the Yellows first. Have you got a solution, do you think?
0:21:22 > 0:21:25- ALL: Yeah. Pretty much.- Yeah? You're pretty confident with that?
0:21:25 > 0:21:27- ALL: Yeah.- Oh, good, right.
0:21:27 > 0:21:28- Shall we try it?- ALL: Yeah. Sure.
0:21:28 > 0:21:33Now, remember, you must have both hands on the rope at all times.
0:21:33 > 0:21:35- DRUMROLL - Are you ready?
0:21:35 > 0:21:38- Your minute starts...now! - KLAXON BLARES
0:21:38 > 0:21:42- Cross over, cross over. - Am I going under?- Yeah.
0:21:42 > 0:21:46- I go like that?- No, it's not there.
0:21:46 > 0:21:48Is this Daniel's hand?
0:21:48 > 0:21:50- Yeah, that's my hand.- OK.
0:21:57 > 0:21:59If you're all talking at the same time,
0:21:59 > 0:22:02you won't be able to hear the coding from Dr Taylor.
0:22:02 > 0:22:04- Over that rope.- Am I going down?
0:22:04 > 0:22:07No, no, no, back a bit, lift it up.
0:22:07 > 0:22:09And down, yep. And the next one.
0:22:09 > 0:22:10Right, there.
0:22:10 > 0:22:11And now you...
0:22:11 > 0:22:14Clear instructions, Dr Taylor, you've got to tell them what to do.
0:22:14 > 0:22:16And, erm...
0:22:16 > 0:22:20- You've got 25 seconds to go. - Come back out, Daniel.
0:22:20 > 0:22:22Keep hold of the rope.
0:22:22 > 0:22:25- No, out, step...- He's gone back.
0:22:25 > 0:22:27No, no, no, actually, under, or...
0:22:29 > 0:22:31- Ten seconds.- Now go under.
0:22:31 > 0:22:33Climb under?
0:22:33 > 0:22:34Stand up.
0:22:34 > 0:22:35HEARTBEATS
0:22:35 > 0:22:36And step back over.
0:22:36 > 0:22:38- Step back over.- No, no, other way.
0:22:38 > 0:22:39KLAXON BLARES
0:22:39 > 0:22:42That's time up, that's time up. Let's have a look.
0:22:42 > 0:22:45Yes, I don't think you quite managed it, did you?
0:22:45 > 0:22:47Unfortunate, that.
0:22:55 > 0:22:56Unlucky, Yellows!
0:22:56 > 0:22:59Let's see if the next team do any better.
0:22:59 > 0:23:01# Bars and Molly-dy... #
0:23:01 > 0:23:04- Now, blindfolds on.- Yep.
0:23:04 > 0:23:06Everybody's got their hands on the rope.
0:23:06 > 0:23:09Now, remember, you cannot take your hands off the rope
0:23:09 > 0:23:10- at any point.- Yep.
0:23:10 > 0:23:13- Are you ready, team? - ALL: Yep.- Shall we do it?
0:23:13 > 0:23:14We shall try.
0:23:14 > 0:23:17Let's do it! Your minute starts right now!
0:23:17 > 0:23:19KLAXON BLARES
0:23:19 > 0:23:21OK, guys, you want to kind of loop it round like that,
0:23:21 > 0:23:23you want to kind of bring your hands up.
0:23:23 > 0:23:25When you say, "Loop around like that,"
0:23:25 > 0:23:26don't forget they can't see you.
0:23:26 > 0:23:28Yes, I'll remember that.
0:23:28 > 0:23:30That's...
0:23:30 > 0:23:32OK, cool, so bring your hands down.
0:23:32 > 0:23:33Keep your hands there, Leo.
0:23:41 > 0:23:45- Is that knotted?- That is a knot! We have a knot, ladies and gentlemen!
0:23:45 > 0:23:47- THEY WHOOP - They've done it!- Party central!
0:23:47 > 0:23:50- I told you.- So you worked well as a team there, didn't you?
0:23:50 > 0:23:51You listened to the coding.
0:23:51 > 0:23:53- Well done, there, Blues. - Thank you very much.
0:23:53 > 0:23:56Well, let's see how the Greens get on.
0:23:56 > 0:24:01Mean, Green coding machine. Let's do it.
0:24:01 > 0:24:02No point hanging about, is there?
0:24:02 > 0:24:04Here we go, your time starts...
0:24:04 > 0:24:05- now! - KLAXON BLARES
0:24:05 > 0:24:11- Go low. Abado, go low.- Yep.- Now move forwards, keep stepping forwards.
0:24:11 > 0:24:14Keep... Yep, yep.
0:24:14 > 0:24:16Almost over, almost over.
0:24:16 > 0:24:19OK, now, you need to duck. Go under.
0:24:30 > 0:24:32Yeah, step out and now pull.
0:24:34 > 0:24:37Yeah, we have a knot. Very well done!
0:24:37 > 0:24:40Let's see. Oh, look at that!
0:24:40 > 0:24:42It's a perfect knot, that is!
0:24:42 > 0:24:44Very, very good, I'm impressed by that.
0:24:44 > 0:24:46You worked really, really well.
0:24:46 > 0:24:48Now, why do you think that worked so well?
0:24:48 > 0:24:49Cos I have a clear voice.
0:24:49 > 0:24:52- POSH ACCENT: - Because she has a clear voice.
0:24:52 > 0:24:55- Do you think it's because you work well as a team?- ALL: Yeah.
0:25:00 > 0:25:04Now, as a final mild-melting round approaches,
0:25:04 > 0:25:07let's find out the scores!
0:25:07 > 0:25:09CHEERING
0:25:21 > 0:25:24At some point, even the brainiest of super-geniuses
0:25:24 > 0:25:29find themselves faced with an almost impossible challenge -
0:25:29 > 0:25:31measuring the power of an exploding star,
0:25:31 > 0:25:34finding the edge of the universe,
0:25:34 > 0:25:36not burning the end of your tongue on hot chocolate.
0:25:36 > 0:25:37Ouch! Still hurts!
0:25:37 > 0:25:40But all of these challenges are nothing, nothing,
0:25:40 > 0:25:41nothing, I tell you! Nothing!
0:25:41 > 0:25:45In comparison to the quickfire round!
0:25:45 > 0:25:47BULLETS WHIZZ
0:25:50 > 0:25:52So it's points to play for and victory the prize.
0:25:52 > 0:25:54- Are you ready, GP? - I'm ready, Dr Brain.
0:25:54 > 0:25:56Hands on your desks, teams!
0:25:56 > 0:25:58Two points for each correct answer.
0:25:58 > 0:26:02No points for a wrong answer. Your 60 seconds start...
0:26:02 > 0:26:06NOW! Which planet is famous for its gigantic rings?
0:26:06 > 0:26:07- MOOING - Greens!
0:26:07 > 0:26:09- Saturn.- It's the right answer!
0:26:09 > 0:26:12What is the most common gas in Earth's atmosphere?
0:26:12 > 0:26:14- MOOING - Greens?
0:26:14 > 0:26:15Oxygen.
0:26:15 > 0:26:17- It's nitrogen.- Oh!
0:26:17 > 0:26:20What do most monkeys have that apes do not?
0:26:20 > 0:26:22Is it a tail or a smartphone?
0:26:22 > 0:26:23ROARING
0:26:23 > 0:26:25- Blues?- Smartphone.
0:26:25 > 0:26:27No, it's a tail!
0:26:27 > 0:26:30What is the layer that protects the Earth from ultraviolet radiation?
0:26:30 > 0:26:31- KLAXON BLARES - Oh, no, that's time up!
0:26:31 > 0:26:34That's time up, I'm afraid. No time to answer that one.
0:26:34 > 0:26:36That was a quickfire-tastic round.
0:26:36 > 0:26:38You was all, like, buzzing and answering and buzzing and stuff
0:26:38 > 0:26:41and I'm hugely impressed by your brainy bravery, all of you,
0:26:41 > 0:26:42even if you did fluff a few,
0:26:42 > 0:26:43but it's better to have fluffed
0:26:43 > 0:26:46than huffed and puffed and never fluffed at all.
