0:00:02 > 0:00:04HE SLURPS
0:00:04 > 0:00:07- Guinea Pig.- Yes, Dr Brain?
0:00:07 > 0:00:10Did you hear about the man who got hit on the head by a can of cola?
0:00:10 > 0:00:12Got hit on the head with a can of cola?
0:00:12 > 0:00:13That's really dangerous, Dr Brain.
0:00:13 > 0:00:15- No, it...- When's somebody going to do something
0:00:15 > 0:00:17about falling cans of cola?
0:00:17 > 0:00:19This has been going on for far too long.
0:00:19 > 0:00:22I'm going to do something about it. I'm going to print up some flyers
0:00:22 > 0:00:24- about the dangers of falling cans of cola.- It's...
0:00:24 > 0:00:27That's what I'm going to do. I'm going to do it right now.
0:00:27 > 0:00:30This is ridiculous. How much longer is this going to go on for?
0:00:30 > 0:00:33It was a joke! It... Oh, forget it.
0:00:33 > 0:00:35Oh, let's get on with the show, I suppose.
0:00:42 > 0:00:46What happens when this mysterious gloop meets a magnetic force?
0:00:46 > 0:00:50Can our teams help GP clear up this colourful downpour?
0:00:50 > 0:00:54Plus, see our teams get to grips with gravity.
0:00:54 > 0:00:55- Yes, Katie!- Yes!
0:00:55 > 0:00:57Get those magnificent minds at the ready.
0:00:57 > 0:01:02This is Ultimate Brain!
0:01:02 > 0:01:06CHEERING AND APPLAUSE
0:01:06 > 0:01:10HE HUMS A FANFARE
0:01:10 > 0:01:13Budget constraints - I've got to do my own fanfare these days.
0:01:13 > 0:01:16Oh, well. My name is Dr Brain
0:01:16 > 0:01:21and I am on a mission to seek out new civilisations, to boldly...
0:01:21 > 0:01:22Oh, that's Captain Kirk.
0:01:22 > 0:01:25Oh, well, you think you're smarter than me, do you, eh?
0:01:25 > 0:01:27Huh? Well, are you? Well, can you do this?
0:01:29 > 0:01:31Didn't think so. Let's do this thing.
0:01:33 > 0:01:35Let's meet our teams. First up, please eat your greens...
0:01:35 > 0:01:37I mean, greet our Greens from Oxford.
0:01:37 > 0:01:41It's Ky, Fern and Lorna.
0:01:42 > 0:01:44From Leeds, so very mellow in yellow,
0:01:44 > 0:01:48it's Summer, Helen and Hannah.
0:01:48 > 0:01:50And our sensational celebrity team in blue
0:01:50 > 0:01:52taking a break from hard work at the CBBC office.
0:01:52 > 0:01:56It's Katie, Karim and Lauren.
0:01:56 > 0:02:00You know, I'm feeling a pretty smug half-man, half-monkey right now
0:02:00 > 0:02:04because I have gathered some of the finest genius science minds
0:02:04 > 0:02:07in the world, and I'd like you to meet them.
0:02:07 > 0:02:11Here they are. Let's begin with the Blues.
0:02:11 > 0:02:13- CHEERING AND APPLAUSE - Hey!- Now, then, Dr Karim.
0:02:13 > 0:02:17- Yes, hello.- Bit of an actor? - Yes.- He likes to think so.
0:02:17 > 0:02:20Have you ever played anything non-human?
0:02:20 > 0:02:23- I played Simba in The Lion King. - Oh!- I did.
0:02:23 > 0:02:25- So, yeah, played a lion, so...- Bit of the old...
0:02:25 > 0:02:28# I just can't wait to be king. #
0:02:28 > 0:02:31Thank you! APPLAUSE
0:02:31 > 0:02:34Tell you something, you know that monkey Rafiki?
0:02:34 > 0:02:37- Yes.- He's my uncle.- He's your uncle? - Yeah, he don't do it no more.
0:02:37 > 0:02:40He works down the East End now selling dodgy mobile phones.
0:02:40 > 0:02:41- In the market?- Yeah, that's right.
0:02:41 > 0:02:43- I thought I knew him. - What's your team name?
0:02:45 > 0:02:46Yeah!
0:02:46 > 0:02:50Now, let us meet the next team. They are in green.
0:02:50 > 0:02:53- How are you, Greens?- Fine, thanks, Mr Brain.- Where are you from?
0:02:53 > 0:02:56- Oxfordshire.- Fantastic. Do you like your science?
0:02:56 > 0:02:58- ALL:- Yeah.- Love it.- Good.
0:02:58 > 0:03:01- Now, Dr Ky, I hear you're into your cars.- Yeah.
0:03:01 > 0:03:03When you're old enough to drive,
0:03:03 > 0:03:06which I calculate will be about 2022,
0:03:06 > 0:03:09- something like that, I should imagine...- Yeah.
0:03:09 > 0:03:11..what do you think cars will be like?
0:03:11 > 0:03:15Cars that can go on sea and turn into a plane,
0:03:15 > 0:03:17and then go on roads, so it'll be an all-terrain vehicle.
0:03:17 > 0:03:19Fantastic.
0:03:19 > 0:03:25It's sleek, it's handsome and it goes at 100,000mph,
0:03:25 > 0:03:26and that's just me!
0:03:26 > 0:03:29- Hey!- Thank you. What's your team name?
0:03:31 > 0:03:34- Serious About Science. - Ooh, I like it.
0:03:34 > 0:03:37Now, last, but by no means least,
0:03:37 > 0:03:39it's the Yellows!
0:03:39 > 0:03:41- How are you, Yellows? ALL:- Good.
0:03:41 > 0:03:42- Feeling happy? ALL:- Yes.
0:03:42 > 0:03:45- Pleased to be here? ALL:- Yes. - Well, that's a good start, isn't it?
0:03:45 > 0:03:49Now then, now then, I here one of you is a little bit of a joker.
0:03:49 > 0:03:51- Is that right?- Yes.
0:03:51 > 0:03:53Would it happen to be you, Dr Summer?
0:03:53 > 0:03:56- Yes.- Bit of a comedian, eh?- Yeah.
0:03:56 > 0:03:57Come on, then. Tell us a joke. Go on.
0:03:57 > 0:04:00What do you call a teacher that's always late?
0:04:00 > 0:04:01Ooh, I don't know. Go on, tell us.
0:04:01 > 0:04:04- Mr Bus.- Hey! HE LAUGHS
0:04:04 > 0:04:07That's much better than my jokes. You don't want a job, do you?
0:04:07 > 0:04:09HE LAUGHS And what's your team name?
0:04:11 > 0:04:15Fantastic to meet you all, my marvellous teams.
0:04:15 > 0:04:18So, this is the show with a need for speed,
0:04:18 > 0:04:23cravings for creativity and ingenious inventions.
0:04:23 > 0:04:25And first, it's the warm up!
0:04:27 > 0:04:30Not that type of warm up, GP.
0:04:30 > 0:04:32Bring me my questions of fire.
0:04:32 > 0:04:34Thank you very much.
0:04:34 > 0:04:39Now, so, we have five questions worth two points each,
0:04:39 > 0:04:41which means there is a maximum amount
0:04:41 > 0:04:42of how many points, Dr Lauren?
0:04:42 > 0:04:46- Ah!- Ten. Ten.- Ten. Ten, ten, ten! - SHE LAUGHS
0:04:46 > 0:04:49- That's bad. That is bad. - With a little bit of help.
0:04:49 > 0:04:50He's the best, Dr Karim.
0:04:50 > 0:04:53We've got the best. He's the Karim of the crop.
0:04:53 > 0:04:55HE LAUGHS Get it? The Karim of the crop?
0:04:55 > 0:04:59Let's do it. Here we go. Hands on brains. Question one.
0:05:05 > 0:05:07'Hacker's Angels.'
0:05:07 > 0:05:08Eight.
0:05:08 > 0:05:10Is the right answer. THEY CHEER
0:05:10 > 0:05:14Question two. What word am I spelling backwards?
0:05:22 > 0:05:23'Hacker's Angels.'
0:05:23 > 0:05:25- Friction.- Is the right answer!
0:05:25 > 0:05:28THEY CHEER Another two for Blue.
0:05:28 > 0:05:31Question three. Get your listening ears on.
0:05:31 > 0:05:33What is this sound?
0:05:33 > 0:05:38POPPING
0:05:38 > 0:05:39'Kids SAS.'
0:05:39 > 0:05:41Um, popcorn popping.
0:05:41 > 0:05:44Is the right answer! THEY CHEER
0:05:44 > 0:05:48- You like your popcorn, Ky. - Maybe.- Question four.
0:05:48 > 0:05:49How many letters are there
0:05:49 > 0:05:52in the word chemistry?
0:05:52 > 0:05:53'Kids SAS.'
0:05:53 > 0:05:55- Seven.- No, it's not
0:05:55 > 0:05:57- the right answer.- 'Hacker's Angels.'
0:05:57 > 0:05:58- Eight.- Is not the right answer.
0:05:58 > 0:06:00THEY SHOUT ANGRILY
0:06:00 > 0:06:03- Nine.- Is the right answer. Well done.
0:06:03 > 0:06:07Last question. Arrange yourselves in order
0:06:07 > 0:06:11smallest to biggest of your left hand. Go!
0:06:11 > 0:06:14Who's got the smallest left hand? Who's got the biggest left hand?
0:06:14 > 0:06:17- 'Kids SAS.'- Greens, let's have a look. Hold them up.
0:06:17 > 0:06:18I think that's actually wrong.
0:06:18 > 0:06:20I think, Dr Ky, you've got the biggest hands.
0:06:20 > 0:06:23- 'Science Sisters.' - OK, Yellows, let's have a look.
0:06:23 > 0:06:25I do declare you're right.
0:06:25 > 0:06:28That's good. Well done, you Yellows.
0:06:28 > 0:06:31Well, there we go. That was the warm up round
0:06:31 > 0:06:33and I am boiling. HE LAUGHS
0:06:33 > 0:06:35Blues and Yellows are off to a flying start,
0:06:35 > 0:06:37but Greens aren't far behind.
0:06:43 > 0:06:47HE CACKLES Welcome to my laboratory.
0:06:47 > 0:06:49Mwah-ha-ha-ha-ha-ha!
0:06:49 > 0:06:52Ooh, sorry about that. Went a bit evil for a second.
0:06:52 > 0:06:55So, everybody, anybody hungry?
0:06:55 > 0:06:57I've got a bit of balsamic vinegar here.
0:06:57 > 0:06:59I thought we could dip some bread in there. That'd be nice.
0:06:59 > 0:07:01Oh, no, wait, wait, wait, wait, wait!
0:07:01 > 0:07:05It's not really balsamic vinegar. Don't eat it, whatever you do.
0:07:05 > 0:07:08- What do you think it is?- Oil. - It looks like oil, doesn't it?
0:07:08 > 0:07:12- Petrol?- Petrol. Could be petrol. - Treacle.- Or treacle.
0:07:12 > 0:07:14- Soy sauce.- Soy sauce. Could be soy sauce.- Yeah.
0:07:14 > 0:07:17Or paint. I'm going to tell you what it is.
0:07:17 > 0:07:20It's called ferrofluid.
0:07:20 > 0:07:23Fe. Does anybody know the element Fe?
0:07:23 > 0:07:26- Magnesium?- Is it iron? - It is iron, yes.
0:07:26 > 0:07:28Little bits of iron in there.
0:07:28 > 0:07:30So, now, what we want to find out -
0:07:30 > 0:07:35what's going to happen when I crank up the electromagnet?
0:07:35 > 0:07:37What's going to happen?
0:07:37 > 0:07:39We have some options for you.
0:07:39 > 0:07:40Is it going to be...
0:07:42 > 0:07:44North to south, you know what I mean?
0:07:55 > 0:07:58Something not even I have thought of.
0:07:58 > 0:08:00Is that even possible?
0:08:00 > 0:08:05Ah, time to get your thinking brains on, my fine friends.
0:08:05 > 0:08:09Your thinking time starts now! KLAXON BLARES
0:08:09 > 0:08:11Something else because I think it might...
0:08:11 > 0:08:14So, four choices here.
0:08:14 > 0:08:16With metal, right, when you put it hot...
0:08:16 > 0:08:19- It bubbles.- ..it's still a liquid. - It bubbles?
0:08:19 > 0:08:22- Or D, something else? B?- C, C, C, C.
0:08:22 > 0:08:25Have you got your answer? ALARM BLARES
0:08:25 > 0:08:27There we go! Thinking time is done.
0:08:27 > 0:08:29Thinking time is over. No more thinking.
0:08:29 > 0:08:30Switch your brains off.
0:08:30 > 0:08:34OK, let's have a look at your answers now!
0:08:36 > 0:08:39- We're outnumbered.- Oh, no. - I-I-I said go for D.
0:08:39 > 0:08:41To be fair, Karim wanted to go for D.
0:08:41 > 0:08:44- I did say that, but I was overruled by the ladies.- I think it's A
0:08:44 > 0:08:47because I think, when you have a magnet,
0:08:47 > 0:08:49- you have a positive end and a negative end...- Correct.
0:08:49 > 0:08:52- So, it makes sense...- Yes. - ..that the electrical charge would
0:08:52 > 0:08:54- send it...- Make a line.
0:08:54 > 0:08:56That seemed like the most logical option
0:08:56 > 0:08:57and I couldn't think of anything for D.
0:08:57 > 0:09:00- We thought, "It won't jump out. That'd be crazy."- It might.
0:09:00 > 0:09:03- We really would like it to jump out, though.- Yellows?
0:09:03 > 0:09:06We didn't think it was going to be any of the A, B or C ones, so...
0:09:06 > 0:09:07- You rejected all of those?- Yes.
0:09:07 > 0:09:10- She thinks it's going to go spiky. - I don't know why.
0:09:10 > 0:09:13- When you say spiky, what do you mean?- Like...
0:09:14 > 0:09:17- Form little spiky things?- Yeah.
0:09:17 > 0:09:18- Ooh, like a little hedgehog?- Yeah.
0:09:18 > 0:09:21That would be funny, wouldn't it? HE GIGGLES
0:09:21 > 0:09:22I like the idea of that.
0:09:22 > 0:09:25- And you've gone for D, as well. - We think it might
0:09:25 > 0:09:27- bubble.- Bubble.- Bubble up. - Bubble?- Yeah.
0:09:27 > 0:09:30Oh, right. Hubble, bubble, toil and trouble.
0:09:30 > 0:09:33That would be very interesting, wouldn't it? OK.
0:09:33 > 0:09:36So, we've gone for form into a straight line,
0:09:36 > 0:09:39make funny little spikes, and bubble.
0:09:39 > 0:09:41Three very different,
0:09:41 > 0:09:43but equally wonderful and scientific answers.
0:09:43 > 0:09:46- Shall we find out what happens? ALL:- Yes.- Let's crank it up.
0:09:46 > 0:09:49Are you ready? Here we go.
0:09:49 > 0:09:50Robot hand.
0:09:53 > 0:09:57- ALL:- Three, two, one, zero!
0:09:57 > 0:09:59Here we go! Turning it up. Turning...
0:09:59 > 0:10:01What's happening? Oh, something is happening.
0:10:01 > 0:10:03Oh, it's formed into...
0:10:03 > 0:10:05- Spikes!- Oh, it's little spikes. - Oh, my goodness!
0:10:05 > 0:10:07- Oh, they are spikes. - That's so weird.- Little spikes.
0:10:07 > 0:10:09- Look. Have a look closely. - It's freaking me out.
0:10:09 > 0:10:11- That is amazing.- So weird.
0:10:11 > 0:10:13- It's bubbling and spiky. - Like little moving triangles.
0:10:13 > 0:10:17- That is amazing.- You got it right, Summer. That is awesome.- Fantastic.
0:10:17 > 0:10:19- How did you know that? - You hit the nail on the head.
0:10:19 > 0:10:22Billions of tiny rocks containing iron
0:10:22 > 0:10:25suspended within the oil act like mini magnets.
0:10:25 > 0:10:28They're normally jumbled up, so their magnetism isn't really seen,
0:10:28 > 0:10:30but when we produce a magnetic field going up through them,
0:10:30 > 0:10:32they line up and start to repel each other.
0:10:32 > 0:10:34This is what makes the hedgehog-like spikes.
0:10:34 > 0:10:37Amazing stuff. And it's not just spooky and weird.
0:10:37 > 0:10:41It's also used in cutting-edge medicine and things like that.
0:10:41 > 0:10:44So, D was right, which means both the Greens and the Yellows
0:10:44 > 0:10:46get the five points for getting the right letter,
0:10:46 > 0:10:49but for getting it bang on the head,
0:10:49 > 0:10:51the Yellows get ten! CHEERING AND APPLAUSE
0:10:51 > 0:10:53Well done, you Yellows.
0:10:53 > 0:10:54Well done, everybody.
0:10:54 > 0:10:57- You, mate, get nothing.- D'oh!
0:10:57 > 0:10:58Time for the next round.
0:11:04 > 0:11:07I had that Professor Brian Cox round the other day.
0:11:07 > 0:11:08He's a good mate of mine.
0:11:08 > 0:11:10You know, celeb friend and all that. He said to me...
0:11:10 > 0:11:13IMITATES BRIAN COX: "You know, one of the great wonders
0:11:13 > 0:11:16"of the universe is that we're all made up
0:11:16 > 0:11:19"of billions of these atoms.
0:11:19 > 0:11:23"Wouldn't it be great if we could do an experiment with these atoms
0:11:23 > 0:11:26"to see if we could expand them into colourful balls?"
0:11:26 > 0:11:29So, we did and they exploded everywhere
0:11:29 > 0:11:32and it's been raining multicoloured balls ever since
0:11:32 > 0:11:34and my swimming pool is full of them.
0:11:34 > 0:11:38D'oh! Luckily, I have with me some of the greatest scientific minds
0:11:38 > 0:11:40the world has ever known and they have come up
0:11:40 > 0:11:44with their own inventions to help me to empty my pool
0:11:44 > 0:11:46of these little balls.
0:11:46 > 0:11:50They each had a budget of £50
0:11:50 > 0:11:53and two days to come up with their creations.
0:11:53 > 0:11:57Teams must think of a way to help GP rescue as many balls as he can
0:11:57 > 0:11:59from the Ultimate Brain swimming pool
0:11:59 > 0:12:02and place them safely into a container at the side.
0:12:02 > 0:12:04GP can move the balls whilst in or out of the pool
0:12:04 > 0:12:07and designs must consider how to quickly and efficiently
0:12:07 > 0:12:10transfer them into the container before the time runs out.
0:12:10 > 0:12:13The team with the most balls in the container at the end of play
0:12:13 > 0:12:16will be awarded a massive ten Honour Points.
0:12:16 > 0:12:18He's always on the ball.
0:12:18 > 0:12:21Well, he's sometimes on the ball.
0:12:21 > 0:12:23No, he's never on the ball, is he?
0:12:23 > 0:12:27It's my good friend Mr Guinea Pig!
0:12:27 > 0:12:31CHEERING AND APPLAUSE
0:12:31 > 0:12:33- ALL:- Oh!
0:12:33 > 0:12:36It's raining snooker balls, Dr Brain.
0:12:36 > 0:12:39- Guinea Pig, are you feeling wet?- Very.
0:12:39 > 0:12:42Well, you're going to be. HE LAUGHS
0:12:42 > 0:12:45Here I am with my good friends the Science Sisters.
0:12:45 > 0:12:49Sounds like a band, doesn't it? You could be a girl group.
0:12:49 > 0:12:50- What would your song be?- Er...
0:12:50 > 0:12:53# Iron filings I love those iron filings. #
0:12:53 > 0:12:55That would be the song for you.
0:12:55 > 0:12:57So, this is your plan. What's it called?
0:12:57 > 0:13:00- The Super Scooper. - The Super Scooper.
0:13:00 > 0:13:02- Yes.- And what is the theory behind your plan?
0:13:02 > 0:13:05Cos it's a net, it lets all the water out when it gets the balls,
0:13:05 > 0:13:07so it doesn't, like, overflow,
0:13:07 > 0:13:10- so the balls don't fall out, as well.- Ah, I see.
0:13:10 > 0:13:13So, you've got a lot of sort of surface area there...
0:13:13 > 0:13:15- Mm-hm.- ..to catch the balls into.
0:13:15 > 0:13:17And there's obviously holes in the net there
0:13:17 > 0:13:18and that's going to help with
0:13:18 > 0:13:21- sort of filtration...- Yeah. - ..to get rid of the...
0:13:21 > 0:13:23Are you worried about the weight of the balls?
0:13:23 > 0:13:24Dr Helen, what do you think?
0:13:24 > 0:13:27Yes, that Hula Hoop already looks floppy.
0:13:27 > 0:13:30- Yeah.- It does a little, doesn't it? This could be a problem.
0:13:30 > 0:13:32You've always got to look for the problems,
0:13:32 > 0:13:34isn't that right, GP?
0:13:34 > 0:13:38The Science Sisters' Super Scooper uses a Hula Hoop as a net holder
0:13:38 > 0:13:41to provide a large surface area with water drainage.
0:13:41 > 0:13:42Attached to the end of a stick,
0:13:42 > 0:13:45GP can steer the hoop from outside the pool
0:13:45 > 0:13:46to collect as many balls as he can,
0:13:46 > 0:13:49but will that large net prove too cumbersome
0:13:49 > 0:13:51when battling against the weight of the balls
0:13:51 > 0:13:52and resistance of the water?
0:13:52 > 0:13:54I've heard of playing a game of pool before,
0:13:54 > 0:13:58- but this is ridiculous, Dr Brain. - HE LAUGHS
0:13:58 > 0:14:03Let's do this thing in three, two, one, go, GP!
0:14:03 > 0:14:06- Go, go, go!- OK, scoop it up. - Scoop them, scoop them.
0:14:06 > 0:14:08Pick them up, pick them up.
0:14:08 > 0:14:11The big question is - is he going to be able to pick them up...
0:14:11 > 0:14:14- Yes!- ..and deposit them into the orange box of science
0:14:14 > 0:14:15- at the end there?- Oh, gosh, no.
0:14:15 > 0:14:19Ah. I see a problem here. How does he...?
0:14:19 > 0:14:22- Oh.- Hmm.
0:14:22 > 0:14:24THEY LAUGH
0:14:24 > 0:14:27Just keep on doing that until you've got loads.
0:14:27 > 0:14:29- That isn't going to work. - Yeah.- Oh, it's in.
0:14:29 > 0:14:32Flip it over like you did. Like that.
0:14:32 > 0:14:35- Yeah, that's it, that's it, that's it.- Just keep on doing that.
0:14:35 > 0:14:37Keep doing that. Quicker, quicker! Go, go, go!
0:14:37 > 0:14:39Even Guinea Pig is using his brain.
0:14:39 > 0:14:41That's quite unusual.
0:14:41 > 0:14:42- Yes, yes!- Yeah.- Oh, yes.
0:14:42 > 0:14:44KLAXON BLARES
0:14:44 > 0:14:46Oh, there we go. That's time up.
0:14:46 > 0:14:48How do you feel that went?
0:14:48 > 0:14:51- Oh, not as good as I hoped. - HE SNORES
0:14:51 > 0:14:55Our idea - we didn't really think through putting it in the box.
0:14:55 > 0:14:58Ah. That was the problem, wasn't it? Scooping them up was fine...
0:14:58 > 0:15:02- Yes.- ..but then depositing them was a little bit tricky.
0:15:02 > 0:15:03Started to get a bit floppy.
0:15:03 > 0:15:06Well, let's see what the next plan is.
0:15:06 > 0:15:10- It's the Blues.- Yes.
0:15:10 > 0:15:13MOBILE PHONE RINGS My phone.
0:15:13 > 0:15:16Ah, thank you very much. Thank you.
0:15:16 > 0:15:19- Hello?- Hello, Dr Brian.- Yes?
0:15:19 > 0:15:23- Just kidding, Dr Brain. - Hacker the Dog. It's your friend.
0:15:23 > 0:15:24- It's not Hacker. - Oh, tell him we're busy.
0:15:24 > 0:15:26- We're busy.- They're a bit busy.
0:15:26 > 0:15:29Do you think your lot are clever enough to be on Ultimate Brain?
0:15:29 > 0:15:32Oh, yes, brainy as they come. Katie's been on Mastermind,
0:15:32 > 0:15:34that Karim's always got his head in a book
0:15:34 > 0:15:36and Lauren knows all there is to know
0:15:36 > 0:15:39about Newton's law of universal gravitation.
0:15:39 > 0:15:41Oh, does she? Thank you very much.
0:15:41 > 0:15:44Yeah, I know Newton's, er, law of universal gravitation.
0:15:44 > 0:15:47- You don't know that.- Yeah, I do. - Let's have it. Let's have it.
0:15:47 > 0:15:50So, Newton's law of universal gravitation states
0:15:50 > 0:15:52that two objects are attracted to each other
0:15:52 > 0:15:56by a force which is proportional to the product of their masses
0:15:56 > 0:15:59and inversely proportional to the square of the distance between them.
0:15:59 > 0:16:04- There you have it. - Amazing, Dr Lauren!
0:16:04 > 0:16:06Right, here we go, then.
0:16:06 > 0:16:08- Winston the Whale. - Winston the Whale.
0:16:08 > 0:16:10We were kind of inspired by nature,
0:16:10 > 0:16:12by big whales who sort of open their mouths
0:16:12 > 0:16:14and scoop up whatever's in the sea.
0:16:14 > 0:16:17And I think we'll be luckier with putting the balls within the box.
0:16:17 > 0:16:19It won't be as hard as the net.
0:16:19 > 0:16:21That should be able to just scoop straight in.
0:16:21 > 0:16:24- We've got a kind of mechanism... - We've got a lever, if you will,
0:16:24 > 0:16:26but it doesn't close completely, so I'm a bit worried.
0:16:26 > 0:16:28- Here is a bit gappy. - I'm a little bit worried.
0:16:28 > 0:16:31HE SCREAMS When whales attack.
0:16:31 > 0:16:33Down, boy. Down, boy. It's all right.
0:16:33 > 0:16:36- Winston, we're on the same team. - We really wanted to get Guinea Pig
0:16:36 > 0:16:38in the water and get him a bit wet and annoyed,
0:16:38 > 0:16:40- so we went for this. - And it's a whale...
0:16:40 > 0:16:42- A whale of a time! - A whale of a time! It's Moby not.
0:16:42 > 0:16:45- THEY LAUGH - Hey!- Brilliant.
0:16:45 > 0:16:48Hacker's Angels have put our GP in the water
0:16:48 > 0:16:50and teamed him up with Winston the Whale.
0:16:50 > 0:16:51Oh, isn't he cute?
0:16:51 > 0:16:53The contraption's mouth-inspired design
0:16:53 > 0:16:55is sizeable enough to capture lots of balls,
0:16:55 > 0:16:57but not so large as to hinder GP's movement around the pool.
0:16:57 > 0:17:00The clasper design allows for water filtration
0:17:00 > 0:17:02and easy release of the balls into the box.
0:17:02 > 0:17:05This whale is about to try to eat some balls.
0:17:05 > 0:17:07Let's see if it works.
0:17:07 > 0:17:12- In three, two, one, go, Guinea Pig! - Come on, Guinea Pig, Winston.
0:17:12 > 0:17:14- Go on, Winston! You can do it! - That's it. Tell him what to do.
0:17:14 > 0:17:16- Quicker!- Give it some elbow grease.
0:17:16 > 0:17:20Get them all in the mouth and then scoop up.
0:17:20 > 0:17:23- Scoop.- Scoop up. - Scoop it up. Pick it up. Lift it.
0:17:23 > 0:17:27- Ooh, it's heavy. - Work those biceps, Guinea Pig!
0:17:27 > 0:17:29THEY CHEER Oh, look at that.
0:17:29 > 0:17:31Scoop!
0:17:31 > 0:17:33Already looking pretty good.
0:17:33 > 0:17:36- Looking pretty good.- Go, Guinea Pig! - Go on, Winston!- Go on!
0:17:36 > 0:17:39- Go on, Guinea Pig!- That's it.- Go on!
0:17:39 > 0:17:43- Ooh!- Go on! - Munching away on those balls.
0:17:43 > 0:17:45- Now, scoop, Winston. - Scoop, scoop, scoop.
0:17:45 > 0:17:46Clock's ticking.
0:17:46 > 0:17:49- Go on. Put your muscles into it! - Go on!
0:17:49 > 0:17:51Yes! Not too bad.
0:17:51 > 0:17:52This is not too bad at all.
0:17:52 > 0:17:54- One more.- Come on, one more.
0:17:54 > 0:17:55- One more go.- A big one, Winston.
0:17:55 > 0:17:58KLAXON BLARES
0:17:58 > 0:17:59Oh, that's it. Time's up!
0:17:59 > 0:18:01Stop, stop, stop!
0:18:01 > 0:18:03- So, how do you think you did there, Blues?- Good, I think.
0:18:03 > 0:18:06- I'm really happy about that. - Worked quite well. ALL:- It did.
0:18:06 > 0:18:08- How was it, Guinea Pig? - I did my best on porpoise.
0:18:08 > 0:18:11- THEY LAUGH Porpoise!- Yes!
0:18:11 > 0:18:14HE HUMS DRAMATICALLY
0:18:14 > 0:18:18Kids SAS, here they are!
0:18:18 > 0:18:23- Hi.- Hello. What is your plan called? ALL:- The Wormzilla.
0:18:23 > 0:18:26- It was inspired by a worm. - Because of the tube.- Wormzilla.
0:18:26 > 0:18:30So, tell me, what is the plan behind the plan? What's the theory?
0:18:30 > 0:18:34Well, if Guinea Pig scoops it up and then he lifts it above his head,
0:18:34 > 0:18:37the balls will go diagonally down to the bucket.
0:18:37 > 0:18:38- Yeah, like that.- Oh, I see.
0:18:38 > 0:18:42So, the balls are going to go into the opening...
0:18:42 > 0:18:44And the poles help him to lift it higher.
0:18:44 > 0:18:46You've got holes in the opening, as well,
0:18:46 > 0:18:48- so you don't get lots of water. - Yeah, the water comes out.
0:18:48 > 0:18:51- It's going to come dripping out and score you lots of points.- Yes.
0:18:51 > 0:18:53- Lots of points. - Hopefully. Fingers crossed.
0:18:53 > 0:18:57Kids SAS's Wormzilla plan has gravity at its heart.
0:18:57 > 0:18:59They've created a water scooper with drainage
0:18:59 > 0:19:00that can be lifted up high
0:19:00 > 0:19:02for the balls to move down a tumble dryer venting tube.
0:19:02 > 0:19:05Does GP have the strength to lift the balls and any water?
0:19:05 > 0:19:08Their tube may be flexible, but will it last the distance?
0:19:08 > 0:19:09It's time to find out.
0:19:09 > 0:19:13Three, two, one, go, Guinea pig!
0:19:13 > 0:19:17- Scoop, scoop, scoop! Lift it up! - Lift it up, lift it up!
0:19:17 > 0:19:19- Ooh, that's heavy.- Lift it up.
0:19:19 > 0:19:22- Good job he's so strong. - Above your head.- Above your head!
0:19:22 > 0:19:24OK, do it again now. Quickly!
0:19:24 > 0:19:26The tube is quite bendy. What's he going to have to do?
0:19:26 > 0:19:28- Oh, no!- Oh!
0:19:28 > 0:19:32- We have a tube malfunction. What can we do?- I broke Wormzilla.
0:19:32 > 0:19:34- What are you going to do? - Scoop it up.- Yeah.
0:19:34 > 0:19:37- Keep going.- Do whatever you can. THEY LAUGH
0:19:37 > 0:19:39The clock is ticking. You've got to do what you can.
0:19:39 > 0:19:42- Go on, Guinea Pig, scoop! - Use your brain, Guinea Pig.
0:19:42 > 0:19:44- What's he going to do? - Scoop it from the other one.
0:19:44 > 0:19:46Put it in! Put it in quickly!
0:19:46 > 0:19:48- Yes!- That's it.
0:19:48 > 0:19:50- Keep doing that.- Yes.
0:19:50 > 0:19:51Get closer to the bucket.
0:19:51 > 0:19:53Get closer to the bucket.
0:19:53 > 0:19:54Time's running out.
0:19:54 > 0:19:56KLAXON BLARES Oh, there we go. That's time.
0:19:56 > 0:19:58Oh!
0:19:58 > 0:20:02Guinea Pig has fallen over, which always makes me laugh.
0:20:02 > 0:20:05HE LAUGHS So, what happened there?
0:20:05 > 0:20:09- Well, the tube wasn't strong enough, so it broke.- Yes.
0:20:09 > 0:20:13- Tumble dryer tube.- Yes.- Little bit too weak, wasn't it? And it snapped.
0:20:13 > 0:20:15That's what's called a malfunction.
0:20:15 > 0:20:17- Do you want to know who won? ALL:- Yes.
0:20:17 > 0:20:20In third place, with 39 balls, it's the Greens.
0:20:20 > 0:20:23In second place, with 99 balls, it's the Yellows.
0:20:23 > 0:20:25But taking ten points, with 246 balls,
0:20:25 > 0:20:27it's the Blues!
0:20:27 > 0:20:30CHEERING AND APPLAUSE
0:20:30 > 0:20:32- ALL:- Winston, Winston, Winston!
0:20:32 > 0:20:34They don't look happy at all, do they?
0:20:34 > 0:20:37It's time for the next round.
0:20:42 > 0:20:45This round is all about super quick reactions.
0:20:45 > 0:20:46Pow!
0:20:46 > 0:20:49What we have here - our lovely teams, of course,
0:20:49 > 0:20:54and they each have their own bottle of Ultimate Cola.
0:20:54 > 0:20:55Now, what we're going to do -
0:20:55 > 0:20:57when you hear the squeal of the guinea pig...
0:20:57 > 0:21:01SQUEALING ..you're going to place your mints
0:21:01 > 0:21:03into your Ultimate Cola bottle
0:21:03 > 0:21:09and we will see which bottle explodes first.
0:21:12 > 0:21:15Ready?
0:21:16 > 0:21:18SQUEALING
0:21:18 > 0:21:21Go on! Go on. Yes!
0:21:21 > 0:21:23- I had it. I had it. - Ooh.- That was me.
0:21:23 > 0:21:28- Oh, it's like a fountain of fun. - A fountain of fun.- I love it.
0:21:28 > 0:21:30Hm, fast minty movement there,
0:21:30 > 0:21:33but not the reaction I'd normally get in the lab.
0:21:33 > 0:21:35Check this one out. HE CHUCKLES
0:21:35 > 0:21:37Here's one I made earlier, as they say on Blue Peter.
0:21:37 > 0:21:40Bubbly, frothy, fizzy fun. HE CHUCKLES
0:21:40 > 0:21:44Cola-mongously pop-tastic.
0:21:44 > 0:21:46The surface of the mints have tons of microscopic layers
0:21:46 > 0:21:48of liquid sugar and all those nooks and crannies
0:21:48 > 0:21:50invite bubbles to form around the mints.
0:21:50 > 0:21:54As the mints sink, the escaping bubbles quickly froth up into a foam
0:21:54 > 0:21:58as the carbon dioxide says, "Get me out of here!"
0:21:58 > 0:22:00Oh, look at that!
0:22:00 > 0:22:03Well, I think you saw it, and I saw it.
0:22:03 > 0:22:06A clear win for the Blues! CHEERING AND APPLAUSE
0:22:06 > 0:22:08Well done, Blues.
0:22:08 > 0:22:10Ten points for you.
0:22:17 > 0:22:21So, GP, what do you know about gravity?
0:22:21 > 0:22:25Gravy tea? Ew! That sounds disgusting.
0:22:25 > 0:22:27No, no, no, no, no, it's not a drink.
0:22:27 > 0:22:29It's the most incredible thing in the universe.
0:22:29 > 0:22:31IMITATES BRIAN COX: Without gravity, you see,
0:22:31 > 0:22:35the universe would just be subatomic particles
0:22:35 > 0:22:38floating around in space because nothing would have come together
0:22:38 > 0:22:41and formed planets and all the wonderful things, and you, you see.
0:22:41 > 0:22:44If it weren't for gravity, there would be no Guinea Pig.
0:22:44 > 0:22:47HE LAUGHS So, we've got a little game
0:22:47 > 0:22:50all about gravity. What the contestants have got to do
0:22:50 > 0:22:55is they've got to push a ball all around our little curved track there
0:22:55 > 0:22:57and into the receptacle at the end.
0:22:57 > 0:22:59Now, this is all about forces, you see.
0:22:59 > 0:23:01If they push it too hard, it'll go flying off.
0:23:01 > 0:23:04If they don't push it hard enough, it'll sort of drip into the middle.
0:23:04 > 0:23:07They've got to use the right amount of force.
0:23:07 > 0:23:11Three, two, one, go! KLAXON BLARES
0:23:11 > 0:23:14- Go, like, round.- Yeah, round. - Put it gently, like...
0:23:14 > 0:23:16Planning. Plotting.
0:23:18 > 0:23:21- They need a little more force. - Try and make it a bit more...
0:23:22 > 0:23:25- One at a time, I think, because... - Go on, Katie.- Oh, no!
0:23:25 > 0:23:28Oh, too hard. You've got to hit the edge, but not...
0:23:28 > 0:23:30- Oh!- Oh, yes!
0:23:30 > 0:23:33The Blues are going at it with enthusiasm
0:23:33 > 0:23:35and the Greens with caution.
0:23:35 > 0:23:37- Outside.- Outside.- Just do it. - Go, go, go! Roll!
0:23:37 > 0:23:39- Ooh!- Keep going.
0:23:39 > 0:23:41Greens are launching a lot of balls,
0:23:41 > 0:23:43but can they get the right trajectory?
0:23:43 > 0:23:45- Ooh!- Yes!
0:23:45 > 0:23:48Aim for the middle. A bit harder, Lauren. That's it, Katie.
0:23:48 > 0:23:50- Oh, Lauren, you've got it. - Have I?- Yeah.
0:23:50 > 0:23:53- Yes, Katie! Yes!- Yeah!
0:23:53 > 0:23:55Yellows are still struggling.
0:23:55 > 0:23:58Too much force there. First, they had not enough
0:23:58 > 0:23:59and now, too much.
0:24:00 > 0:24:03- Ooh!- Oh!
0:24:03 > 0:24:05- Yes.- And another.
0:24:05 > 0:24:07- Oh, yes!- Yes.
0:24:09 > 0:24:10You're on a roll now.
0:24:10 > 0:24:12HE LAUGHS On a roll.
0:24:12 > 0:24:14Nothing for the Yellows yet.
0:24:14 > 0:24:17- Yes!- Yeah! KLAXON BLARES
0:24:17 > 0:24:19That's time up.
0:24:19 > 0:24:20So, then...
0:24:20 > 0:24:24So, who out of you all has the force?
0:24:24 > 0:24:26HE BREATHES HEAVILY
0:24:26 > 0:24:28Sorry, a bit wheezy today.
0:24:28 > 0:24:33But I can reveal, Blues, you got three.
0:24:33 > 0:24:37Yellows, oh, I'm afraid you just got the one.
0:24:37 > 0:24:38Greens...
0:24:39 > 0:24:42- ..three to beat. Do you think you beat three?- Yeah.- Yeah.
