Wolfbrain Ultimate Brain

What's the wobbliest form of transport?

Oh, would it be one of those bendy buses?

Cos all the time you're on them, they're always doing this.

Or it could be, it could be on a bicycle,

-cos they're quite difficult.

-No, no, no.

-Maybe...

Or even a tricycle, I've never even ridden a tricycle.

Or a unicycle, that'd be quite difficult.

I've never ridden a unicycle.

I'm going to give that a go, I'm going to see what that's like.

It's a j... Oh.

Can our teams help Guinea Pig speed his way along a slippery slide?

Who will be speediest at splatting jelly?

And will anyone hit this target?

All that and more, it's time for Ultimate Brain!

CHEERING

Ha-ha-ha-ha! Good to see you again.

Come on, boy, hup,

there he is. My pet flea, Cornelius.

I'm just training him, you see. Ha-ha-ha! Hey, guess what?

If we practise a bit more, we could go on Britain's Got Talent.

And then you could get to meet Simon Cowell!

Where are you going?! I didn't mean it,

you don't really have to meet Simon Cowell.

Oh! I'd better go and get him.

This is Ultimate Brain!

Let's meet the teams.

First, the team in green from delectable Doncaster,

it's Evie, Tom and Dexter!

Brilliant from Brighton, in yellow, it's Daniel, Ben and Sam!

And our celebrity team in blue are The Three Ks from...

HE HOWLS

..Wolfblood.

It's Shorelle, Rachel and Gabrielle.

Once again, just for you,

I have scoured the universe to find some of the brightest minds known to

mankind. And I...

HE GRUNTS

HE HOWLS

Oh, no, something strange is happening to me.

HE HOWLS This can only mean one thing.

Yes, it's time to meet our teams,

beginning with the team from Wolfblood.

They're the Blues!

-How are you, Blues?

-Good.

-Good, thank you.

Good to see you.

Now, we've had a team on from your show before -

Bobby, Louisa and Kedar.

And guess what? They won!

CHEERING AND APPLAUSE

You've got a lot to live up to, haven't you?

HE HOWLS

-Uh-oh.

-We do.

-Let's see how well you do.

What's your team name?

The Three Ks. Thank you.

-Moving on to the Yellows! How are you doing, Yellows?

-Good.

-Nice to see you. Where are you from?

-Brighton.

-Brighton.

Brighton! By the sea. What's your team name?

The Bubbly Brainiacs from Brighton.

Who invent burglar alarms, is that right, Dr Ben?

-Yes.

-What's that all about, then?

Basically, in year four,

we made some burglar alarms and I thought I could test them out

on my sister cos she kept on creeping into my room.

-And what happened?

-I caught her three times.

DR BRAIN LAUGHS

-Did you send her to prison?

-No, I just told my mum.

Ha-ha! I need one of those to stop Guinea Pig from stealing my bananas.

DR BRAIN LAUGHS Here we go, it's the Greens.

How are you, Greens?

-Good.

-Good, thanks.

-Good to meet you.

Dr Dexter, I hear you are a big fan...

MIMICS BRIAN COX: ..of the wonders of the universe.

And what can you tell me about your adventures in space and time?

I know what the centre of a black hole is called,

it's called the singularity.

-Good one.

-And I know the temperature of the core of the sun.

Yes, 15 million degrees, isn't it?

Yes.

Oh! And I've heard you'd quite like to be an astronaut, is that right?

-Or a scientist.

-I think by the time you're old enough to actually be

a professional astronaut,

you might be in time to do the mission to Mars

they keep talking about.

Doop, doop, doop...

-Dexter on Mars, that would be fantastic, wouldn't it?

-Yes.

Brilliant! What's your team name?

Good luck on the show, and luck is what you're going to need because

this is the show with a need for speed,

a craving for creativity

and a demand for ingenious ideas and inventions...

and this is the warm-up!

Not that type of warm-up, Guinea Pig.

Give me my questions!

BELL DINGS Good lad.

Right, are you ready, teams?

Hands on brains. Here we go.

Take two, times it by four, then add seven, then divide by three.

-HOWLS: Three Ks?

-Five?

-Is right!

-Yay!

What word am I spelling backwards?

HOWLS: Three Ks?

Circuit.

Is correct.

What is this sound?

LOUD WIPING

HOWLS: Three Ks.

Windscreen wipers?

-Is right!

-Ooh!

How many letters are there in the word "recycled"?

Knowledgeable Newtons!

Eight.

Is correct!

Now then, put yourselves in order of the length of your hair,

the shortest this side and the longest that side.

And when you've done it, press your brain.

Bubbly Brainiacs.

You've got to have a look.

Yes, I'm going to give it to you.

-Well done!

-Yay!

Wow! What a fantastic warm-up.

And after that, The Three Ks are HOWLING ahead on six points.

CHEERING AND APPLAUSE

MIMICS THE COUNT: Welcome to my laboratory.

Ah, ah, ah!

So, what do you think I've got in front of me,

-what do you think this looks like?

-Newton balls.

Oh, well, it's kind of like it, isn't it?

-What do you think?

-I have seen a Newton's cradle before and the balls

are touching, but those aren't.

They're not, are they? No, it is slightly different actually.

Could be a sort of xylophone... # Brrring-ding-doon-doon. #

Actually, no, it's just a pendulum arrangement that I've made.

The difference between this and the Newton's cradle you talk about

is that the strings on these are all different lengths.

You see, as it goes along the line, they get longer and longer.

What I'm going to ask you is,

when I swing the ball one way

at the exact same time and let them all go,

what is going to happen?

I'm going to give you some options.

A, the balls will click together

and form a sort of groovy drumbeat...

Something that only you, or you, have thought of, and not even I.

What could it be?

Now then, you're thinking time starts now!

-KLAXON BLARES

-C.

So, what will happen when I let go of the balls?

Different lengths means different vibrations means...

It will go like...

The longer the chain...

Have you got your answer?

I think if it pulls back, each one will go one by one, by one, by one.

Isn't that a snake?

ALARM BLARES That's it, time's up!

Let's see your answers...now!

C, C, C.

Everybody has gone for C.

Let's start with the Greens.

Why have you gone for C, Greens?

Partly because I've seen a giant one in action.

-So you're using your memory?

-Yeah.

-Yellows.

-We think it will snake

because longer strings will take longer,

so it will look like a snake.

Ah, I see!

Now then, Blues, you've also gone for C.

What's your scientific thinking?

Well, I think we agree with Dr Ben,

in terms of the different lengths of the string,

so that'll make a snake affect.

Everybody's gone for C. Well, shall we see?

Right, come on, then, let's do it.

Here we go.

I'm going to just gently pull them all out this way,

like this, at the same time, so they are the same distance.

And then, I'm going to let go!

Let's see what happens.

Ah, yes, look!

-ALL:

-Yeah!

-Watch what happens now.

It's starting to wiggle, getting even more snaky,

getting even curlier, isn't it?

There we go, there's our snake.

Whoo! Isn't it fantastic?

-Yeah.

-Beautiful, isn't it?

Ha-ha-ha!

This pendulum swing has been specially designed

to create this mesmerising pattern,

and the key is in the difference in the length of the chains

on which the bob weights hang.

In equilibrium, the forces acting on them are perfectly balanced,

and the strings hang vertically.

But bring in gravity

by lifting and dropping them all from a level height

and that's when the difference in their period of oscillation

comes into play.

The longer the string,

the greater the amount of time it will take to complete one swing of

the circular arc. By careful calculation of each chain's length,

we get this wonderfully wavy effect.

Science in action. Even though they're acting independently,

when viewed together, it looks like they're dancing in motion together.

Ha-ha-ha! The choreography of science.

The first person who really discovered this was Galileo, of...

# Galileo, Galileo, Galileo, Figaro Magnifico... # ..fame.

And he used this to invent the first pendulum clock!

All of you were right.

-Yes!

-You all get ten points!

Well done, teams. Marvellous. ALL CHEER

They've certainly got into the swing of things.

SWING OF THINGS! Points all round.

CHEERING AND APPLAUSE

I've been a bit fed up lately

because I get very tired walking around my laboratory all day.

I get really, really achy feet.

And that last challenge gave me an idea.

How do snakes get around?

Oh, yes, they slip and slide, don't they?

That sounds much easier,

so I've asked my teams to devise ways to make

humans slip really, really fast.

And I gave them a budget of £50 and two days

to come up with their plans.

Teams must think of a way to help GP launch himself onto and travel along

the polythene pathway,

thinking about how to make GP as slippery as possible

as he travels down the slope.

The team whose plan helps GP reach the greatest distance

in the time allowed will win a whopping ten Honour Points!

And who better to test them than my very own Mr Guinea Pig?!

CHEERING Ha-ha-ha!

Uh... My very own Mr Guinea Pig!

It's all right, Guinea Pig, come on. LAUGHTER

-What's the matter?

-I'm not coming out.

-Why?

-Because I heard there's a slippery,

slidey snake somewhere in the studio.

No, it wasn't a real one, it was a pendulum-y thing.

It's you who's going to be slipping and sliding.

-Oh.

-Yeah.

DR BRAIN LAUGHS Come on then, GP!

-That's OK, then.

-You feel a bit better now?

-Yeah.

-Good.

Because we are going to make you fall over again.

LAUGHTER Let's see the first plan.

Um, Yellows, are you big fans of Pingu or something?

-Yeah.

-What's going on?!

What have you got him dressed up like that for?

We thought about penguins.

In the wild, they slide on their bellies to get into the water.

Oh, they do, don't they? You see them going schaaawwwn!

And we've put the hat and the flippers to increase aerodynamics,

so he has to put his head up.

The egg's going to go in-between his legs to increase momentum.

To increase momentum.

-So it's got some weight behind it?

-Yes.

-Oh, I see,

and you're hoping that extra weight

is going to push him a bit quicker down the slide?

-Yes.

-The olive oil and the washing-up liquid

is to lubricate the slide.

He's going to mix it together and then put it on his belly,

so then hopefully he will slide further.

And what's that white thing actually made of?

-We were thinking of a slippy material...

-Yes.

..which will also protect him

when he's sliding down so he doesn't get burnt.

Oh, that's so considerate.

You see, they're thinking about you, Guinea Pig.

They care about you, isn't that lovely?

Ah! They're still going to throw you down a slide, though.

So, I don't think they care about you that much, do they?

The Bubbly Brainiacs have given GP a smooth front to minimise friction

as he comes into contact with the slope.

Plus, they're going all-out using both oil AND washing-up liquid

as lubricants.

They're hoping an egg-shaped weight between GP's legs will aid

his battle against any air resistance, add balance and increase

momentum, putting faith in their lubrication

to counteract any increased drag through friction.

OK, Guinea Pig, get lubricating!

KLAXON BLARES

-Olive oil.

-Open the oil.

Over your belly. Over your belly...

It is quite a slippery substance, olive oil.

And now the washing-up liquid.

Open up the washing-up liquid.

And then squirt that all over your belly.

And then put some of it on the slide.

Three, two, one! ALARM BLARES

You've got to go, Guinea Pig!

You've got to go! He's picking up the rugby egg.

Come on, then, GP.

Off you go.

Splat.

He's trying to move, he's having a wriggle.

-Put your legs down and flap.

-Legs down and flap.

He's pretty much reached about as far as he's going to go, isn't he?

-He's going.

-He's still having a flap.

-Keep going!

You can tell him.

Keep going! Keep going!

Oh, that's a good movement.

But he is getting somewhere.

He's moving... ALARM BLARES

-Time up.

-Yeah!

Hmm. An interesting pairing of lubricants here.

As a detergent, washing-up liquid actually breaks down oil,

with the hydrophobic ends of its hydrocarbon chains

grabbing onto the oil molecules.

That made no odds here, though.

By using such volume of these two super-slippy liquids,

we saw some effective slippage.

HOWLS: It's the Blues. Shorelle, Rachel, Gabrielle.

Otherwise known as...Triple K!

So, Blues, what's the name of your plan?

-ALL:

-The K Ship.

-Ooh!

And the idea is that it's an inflatable rubber spaceship,

so because it's quite light,

it should go far, and because of the foil,

it should glide on top of the slip and slide.

And then we wanted to lubricate it

with some olive oil on the underside.

So it's not a giant bagel, then?

-GIRLS LAUGH

-Sorry!

That's a shame. Guinea Pig, how do you feel?

I feel I should change my name to ET-GP.

LAUGHTER

The Three Ks are hoping to launch GP to victory,

adding tinfoil to a rubber wing.

Combined with the spread of his weight across a larger surface area,

they're hoping this coating

will make for a smoother run, reducing friction.

Their lubricant of choice is olive oil -

for space-age slippery, sliding superpowers.

And similar to the Yellows,

they've added heavy bags of rice that they hope will aid momentum.

Is GP about to rock it down the slope?

Prepare for blastoff!

Let's start your time...now!

-KLAXON BLARES

-Oil.

-Open the olive oil.

Spread it all over the bottom.

Probably put it on your hand.

-Yeah, OK.

-Around the ring.

-Yes. That's it.

-ALL:

-Spread it around with your hands.

And on the next noise, you've got to go, so waiting...

Turn it over. And you're going to go forwards.

He needs to sit in it backwards and push himself with his feet.

-OK, yes...

-ALARM BLARES

-You've got to go!

-Backwards. That way.

-Go, go, go!

-Push back with your feet.

What's he got on his feet?

-He's got rice bags.

-LAUGHTER

It is a bit of a struggle.

Oh, now he's started to move a little bit.

With that little motion he's doing.

He's moving a bit more.

-That was a bad idea.

-Yes!

How else are we...?

We think maybe... ALARM BLARES

-Time's up, I'm afraid. Your time is up.

-Oh!

Did those heavy bags of rice work in opposition to their attempts

to spread out GP's weight across that giant ring?

He certainly wasn't going anywhere fast, was he?

So let's have a look at the Green plan.

Let's hope it's not at all scary.

MUSIC: Jaws Theme Aah! Ooh!

Shark, shark! Ooh... Oh... Oh, it's you, Guinea Pig!

So, Greens, talk me through this plan.

What's going on?

Well, we decided to put Guinea Pig in a streamline

because if you look at bobsleighs,

they're all in a line, it's easier for them to go down.

We have used the bin bag because it's sort of super-slippy.

Oh, I see.

And we've decided to put washing-up liquid all over him,

all over his front.

Ah, yes, that'll make it really slippy.

We used the tape to hold the cotton and the tape together.

Oh, I see, that'll keep it nice and solid, won't it?

Nice and sturdy. Good thinking.

How do you feel, GP?

I feel like I should be called...

Which is the Latin name for a great white shark.

Ooh! Get him! LAUGHTER

Like the Yellows, Knowledgeable Newtons

have been inspired by nature,

turning GP into a super-streamlined slippery shark.

Keeping the design as compact as possible,

they hope to reduce air resistance,

and with a smooth plastic covering to his body,

minimise friction on our slippery slope,

helped further by washing-up liquid.

As with other plans, aiding lubrication.

Will this shark attack kill all hope for the opposition?

Or at least scare them off? Let's find out.

Shark attack.

HUMS JAWS THEME

Let's see it in action, then.

Three, two, one - get lubricating!

-KLAXON BLARES

-Put it all over.

All over, Guinea Pig, literally.

Absolutely everywhere! On your legs.

-Legs!

-Everywhere.

-Put loads on.

-Everywhere!

-You tell him.

-Arms.

-Arms, arms, arms. Legs, legs, legs.

Do it a bit more on your legs.

-Put it everywhere!

-Yes, yes, yes!

Loads and loads and loads.

He looks nice and slippy now. ALARM BLARES

That's it, off you go, Guinea Pig!

-Let's see how he does.

-Go!

Oh, look at that!

-Go, go, go!

-Go on, Guinea Pig.

Like a shark.

-Go on, Guinea Pig!

-What do you think he should do now?

-Guinea Pig!

-See how far he can get.

Oh, he's come to a bit of a standstill.

Need him to go quicker.

-LAUGHTER Slipping away.

-Come on!

-Like a shark out of water.

-Come on, Guinea Pig!

LAUGHTER Oh, he's gone on his side!

-Go, go, go!

-Go on, Guinea Pig!

ALARM BLARES That's your time up!

What a combo of material and lubricant!

With weak forces between the molecules of the fluid

compared to the solid surface,

moving easily between the plastic above and below.

And I can tell you the first result

is that Guinea Pig is absolutely exhausted, look at him.

Poor thing! Ha-ha-ha! You've wiped him out!

Ha-ha-ha! And now I can tell you the second result

is that the team that came in last place...

..was...

HE HOWLS

Perhaps going backwards wasn't such a great plan after all.

Unlucky, unlucky.

I can say, in second place,

meaning they get five points, is the Yellows!

LAUGHTER

I'm awarding five points there because you mirrored nature and

applied that in your science, and I like that kind of thinking.

We reward good thinking on Ultimate Brain.

But that means, of course, you, Greens, get ten points!

-Well done.

-Yay!

A great victory there for the Greens.

Now let's see how they get on in the next round.

CHEERING AND APPLAUSE

Ha-ha! Me and Guinea Pig love a good party, don't we?

Oh, the music, dancing.

Ice cream. And jelly.

Jelly. We hate jelly, don't we?

We hate it! Jelly must be destroyed!

It is what this challenge is all about.

Yes, our three contestants have their jelly in front of them,

and all we're going to do is, on the sound of the Guinea Pig squeal,

they're going to whack their jelly as fast as they can,

and the one who hits their jelly the fastest wins!

Are you ready, teams?

-ALL:

-Yes!

Oh, mercy!

But who was the quickest? Let's have a look at the replay.

Wobbly wowzers!

But whose jiggly jelly was the quickest to quake?

I can't quite tell with the naked eye.

Let's check the slow-motion camera.

Well, that jelly suddenly has all been destroyed,

but one team got smashing first.

Well, we can see it was a victory for the Yellows!

Ten points!

# Jelly on a plate Jelly on a plate

# Wibble wobble, wibble wobble Jelly on a plate. #

Ha-ha! # Jelly on a plate. #

I'm just going to keep singing and dancing

right through to the next round!

Guinea-ma-Pig, what do you know about bouncing?

-Bouncing?

-Yeah.

-I can bounce.

# Bounce, baby, bounce... #

Well, that's good, because this challenge is all about bouncing.

Now, our contestants have got a selection of balls here.

You've got a basketball here.

Do-o-o-o-ing!

Got a tennis ball here.

Sho-o-o-o-ing! And here is a little ball of Blu-tack.

Splat! So, what they've got to do is they've got to try and bounce one or

a combination of any of these balls, bounce them,

and try and hit the target.

But they can only drop the balls, they can't throw them.

Ah! Do you think you could hit the target?

Yeah, I reckon I could do it, Dr Brain.

Go on, then! Give it a go!

I... I meant with one of the balls.

Oh, Guinea Pig. Let's hope our teams are more inspired.

Your time starts...now! KLAXON BLARES

I'm thinking, if we drop the basketball

and then drop the tennis ball on top of the basketball,

and then the Blu-tack on top of the tennis ball.

They should bounce off each other and hit the target.

Straight to it, Dr Shorelle.

-OK, do it.

-OK.

Off to a flying start! LAUGHTER

Right, everyone get one. You go first, Dexter.

-OK.

-OK, that's reasonably good.

Tom, drop it.

That was really bad.

Fire!

We've got to, like... It's shooting that way, so we...

-That ain't going to work.

-Yeah, try it that way.

Now it's shooting that way!

So we all have to drop it at the same time and hope for the best.

OK.

-OK. OK.

-That didn't work.

No, let's try again.

That one, when it hits the floor,

drop another one so that it'll hit that and hopefully reach the target.

-OK, we need to...

-Oh, looks like you're onto something, Greens.

-Or not.

-Keep trying that idea, hopefully...

-Whoa, Yellows!

-You drop when that gets back up.

-OK.

-OK.

-Ready?

-Yeah.

-Go.

-This technique is catching on.

You make sure it's in line.

Three, two, one, go.

-It's not in line.

-Ooh!

-Dr Dexter is not the target!

-Wow.

-So close, Yellows!

Do it again, Ben.

-That way...

-Tom!

-This way...

-Tom!

-LAUGHTER

Any way but up.

Come on!

Ooh, Greens! That was nearly it, that was nearly it!

They've definitely made a discovery here.

-Go on.

-Got it?

-Go on, then.

-No.

Oh!

Go.

Yes! ALARM BLARES

-ALL:

-Oh!

You did it!

Well done!

So, that was a pretty interesting one, wasn't it?

-Yeah.

-Most of you got the principle pretty quickly, didn't you?

But only one team actually managed to hit the target.

Go.

GASPING

Yes!

And that was...the Greens!

Well done, you three. You get ten points.

But because the rest of you got the principle and you nearly,

nearly got it, I'm going to give you two points each.

So, well done to you.

CHEERING AND APPLAUSE

-What do you think this was for?

-Sticking it to the target?

Almost. What you could have done - take a little piece of this...

HE HUMS

Stick the tennis ball onto here, and hopefully what would happen is,

as you take it over,

very elegantly just drop, thuswise...

And there you go.

-ALL:

-Oh!

-ALARM BLARES

The heavier basketball transfers its energy to the lighter tennis ball,

and fixing it in place helps with aim.

Score!

That's how it's done. There you go.

Now it's time for the quickfire round!

Quick, quick, we've got to go!

HE HOWLS

It's a full moon, and time is racing away,

and it's about to get even quicker with the quickfire round.

Are you ready, teams?

-Yeah!

-Hands on brains!

The Komodo dragon is the largest species of which reptile?

Lizard.

Is correct. Which is the shortest month of the year?

'Bubbly Brainiacs.'

-January... No.

-February.

I have to take the first answer, because it was actually February.

How many colours are there in the rainbow?

'Bubbly Brainiacs.'

Eight.

No, it's seven. Which part of your body vibrates when sound reaches it,

enabling you to hear?

-'Knowledgeable Newtons.'

-Ears.

It's the eardrum. I'm going to give you that.

What name is given to the top of an ocean wave?

-'Bubbly Brainiacs.'

-White horses.

No, crest.

True or false? GP once burped with such a force that he fell over.

'Bubbly Brainiacs.'

False.

No, it's true.

Scientists say global warming is primarily caused by an increase in

the atmosphere of which gas?

-'Knowledgeable Newtons.'

-Helium.

No, its carbon dioxide.

How many centimetres are in a metre?

-'Bubbly Brainiacs.'

-100.

Is right.

Which colourful reptile has a tongue that can extend more than...

Chameleon!

Is right. What is a camel's hump made of?

-Muscle...

-Fat.

Is correct, and that's the end of the road!

ALARM BLARES There we go.

So, wow, what an amazing game that was.

So here we go, then, folks, here are the scores.

In third place, with 20 points...

it's the Blues!

CHEERING, DR BRAIN HOWLS

Well done, you Blues, well done.

In second place, with 34 points...

it's the Greens!

Oh, well done, silver medal.

Winning by one point...

-Oh!

-It's the Yellows, with 35 points.

Well done, you Yellows. Magnificently played.

Look how much fun they've had.

They've had fun, I've had fun, have you had fun?

Oh, I so hope you did.

Join us again soon for more Ultimate Brain!

Oh, that was a brilliant one. They were good, weren't they, the...

Oh, hi, there, GP!

Try that joke again. Now, then.

What's the wobbliest form of transport?

Oh, I've been working on my unicycle skills...

-No.

-You know, I think you can do this...

-No, no, no.

But I couldn't get a unicycle,

so I'm thinking of getting a bicycle and cutting it in half.

No, no, no. It's a jelly copter.

Do you get it? A jelly copter.

Because jelly is wobbly.

You see?

What's it like in your world?
