0:00:22 > 0:00:25This was a great choice of yours, Oucho.
0:00:25 > 0:00:28The Choccy-oke, a chocolate covered marshmallow making machine from
0:00:28 > 0:00:31Chloe in Huddersfield. We've got everything we need as well.
0:00:31 > 0:00:34We can get this made in about a day, I reckon.
0:00:34 > 0:00:38Then we can just enjoy the hills of Huddersfield. Are you ready, Oucho?
0:00:40 > 0:00:42- Oucho?- I'm not...hoot.
0:00:42 > 0:00:46What do you mean you're not coming out?
0:00:47 > 0:00:49This invention was your idea.
0:00:49 > 0:00:52Why are you trembling back there like a girly jelly?
0:00:54 > 0:00:56I heard the...Lumpas.
0:00:56 > 0:00:59Ah, monsters. Yes, I should have known there was a perfectly sensible
0:00:59 > 0:01:01- explanation for this.- Oh.
0:01:03 > 0:01:06- Oh... Chloe....Lumpas. - Chloe's brother told you about them?
0:01:06 > 0:01:08Oh...papas.
0:01:08 > 0:01:10Sent you this newspaper?
0:01:10 > 0:01:14What? Beware of cactus eating monsters. Turn to page 4.
0:01:14 > 0:01:17The monsters are extremely scary and dangerous.
0:01:17 > 0:01:20These cactus eating monsters can only be tamed with
0:01:20 > 0:01:22chocolate covered marshmallows.
0:01:22 > 0:01:27- Oucho, this newspaper clearly isn't real.- Oh.
0:01:27 > 0:01:29No. Calm down. Calm down.
0:01:29 > 0:01:33Calm down. No shouting in this van. No shouting in this van.
0:01:33 > 0:01:38- No, no, no, no, if we make this invention will you calm down?- A.
0:01:38 > 0:01:39OK, come on then.
0:01:43 > 0:01:47We're about to surprise Chloe and make her dreams come true.
0:01:47 > 0:01:50- You don't think your anti-monster disguise is a bit over the top?- No.
0:01:50 > 0:01:52Ed... rosa?
0:01:52 > 0:01:55Why would I want a rose?
0:01:55 > 0:01:56I haven't got a girlfriend.
0:01:56 > 0:02:00- Ha-ha.- Oh, it is that again, is it? Ed hasn't got a girlfriend.
0:02:00 > 0:02:02Yes, well, I've had one in the past, so...
0:02:02 > 0:02:04What do you mean what were their names?
0:02:04 > 0:02:06Are you the secret police?
0:02:06 > 0:02:09- No, they didn't have moustaches. - Hm-hmm.
0:02:09 > 0:02:12- Argh.- Hi, Ed. Hi, Oucho.
0:02:12 > 0:02:15- Hello. Sorry, he thinks you are a cactus eating monster.- Help! Help!
0:02:15 > 0:02:18- You're not, are you?- No, I'm not.
0:02:18 > 0:02:22- Disguise?- She is not one in disguise. - Phew.
0:02:22 > 0:02:24- Can we come in?- Yes.
0:02:29 > 0:02:31Oi. Lumpas.
0:02:31 > 0:02:33No, we're not eating you like the monsters.
0:02:33 > 0:02:36This is a cake in the shape of you that Chloe has very kindly
0:02:36 > 0:02:38made for us. Would you like a slice?
0:02:38 > 0:02:40No.
0:02:40 > 0:02:42It wouldn't make you a cannibal.
0:02:42 > 0:02:43I've got work to do.
0:02:43 > 0:02:47Now, Chloe, who do you live with?
0:02:47 > 0:02:50My mum, my dad, and my older brother Daniel.
0:02:50 > 0:02:54Now, it's your brother that I am interested in, where is he now?
0:02:55 > 0:02:58Um, well, he's out.
0:02:58 > 0:02:59Yes.
0:02:59 > 0:03:01Very strange that, because normally
0:03:01 > 0:03:05kids are very excited to meet me, you know, international celebrity.
0:03:05 > 0:03:07They want my autograph and stuff, but your brother he is nowhere
0:03:07 > 0:03:09to be seen. It's suspicious.
0:03:09 > 0:03:12- Very suspicious.- Hurry. Hurry. - All right, all right, all right.
0:03:12 > 0:03:14Let's get on with the invention then.
0:03:14 > 0:03:17I need you to put on this, it is the brainstorm helmet.
0:03:22 > 0:03:27Now, tell me, why do you want to invent the Choccy-oke?
0:03:27 > 0:03:30I'd like to invent the Choccy-oke,
0:03:30 > 0:03:34a chocolate making stall that can go anywhere.
0:03:36 > 0:03:39It has a microphone so I can sing my favourite songs,
0:03:39 > 0:03:42a chocolate fountain so I can dip my marshmallows in,
0:03:42 > 0:03:46and whilst waiting for them to dry I will sing my favourite song.
0:03:52 > 0:03:54I like the sound of this Choccy-oke. Ever since I was
0:03:54 > 0:03:58a kid I always wanted to taste chocolate covered marshmallows.
0:03:58 > 0:04:01Unfortunately, it never really worked out.
0:04:02 > 0:04:04Edward?
0:04:04 > 0:04:07Have you seen that bag of alpaca poo for the garden?
0:04:12 > 0:04:14- Ed?- What? Oh.
0:04:14 > 0:04:16Ah, I'm really going to enjoy
0:04:16 > 0:04:19this invention, I'm looking forward to those marshmallows.
0:04:19 > 0:04:23Sabing ma lie. Sabing ma lie.
0:04:23 > 0:04:26Yes, and saving your life from the cactus eating monsters.
0:04:26 > 0:04:30- Better be quick then, we've only got three days.- Three days?
0:04:30 > 0:04:32I read in the newspaper
0:04:32 > 0:04:35in three days there's going to be thousands of monsters.
0:04:35 > 0:04:36Argh! Argh! Help me.
0:04:36 > 0:04:40- Another headline from the Daily News Newspaper Of News.- Help me. No. No.
0:04:40 > 0:04:43OK, no time to worry about that.
0:04:43 > 0:04:45Let's get inventive.
0:04:49 > 0:04:52All this dressing up is just delaying building the machine.
0:04:52 > 0:04:55Ready.
0:04:55 > 0:04:57Oh, where is Oucho?
0:04:57 > 0:04:59I can't see him anywhere.
0:04:59 > 0:05:02There's just this frog with a moustache in front of me.
0:05:02 > 0:05:04I...
0:05:04 > 0:05:06Oh, it's you. Oh, yes, well, your cunning
0:05:06 > 0:05:10disguise will definitely work. You won't be eaten by any monsters now.
0:05:10 > 0:05:11So can we get on?
0:05:11 > 0:05:14Yeah. I don't think you've thought this through properly.
0:05:14 > 0:05:17We've got all this stuff but how are we going to power it? It will
0:05:17 > 0:05:20need electricity obviously. But how does electricity work?
0:05:20 > 0:05:24Oh, Ed...
0:05:24 > 0:05:27Yeah, I know you get electricity if you rub a balloon on your head,
0:05:27 > 0:05:31but that's not really very helpful, is it?
0:05:31 > 0:05:33How about I rub a balloon on my mum's head?
0:05:33 > 0:05:36- Ha-ha-ha.- That's not funny.
0:05:36 > 0:05:39That doesn't even make sense. This is pointless.
0:05:39 > 0:05:42I need to talk to proper grown-ups, people who know stuff.
0:05:42 > 0:05:45People who've done exams. Come on, let's go and see Danielle Darwin.
0:05:48 > 0:05:51Oh, hello. I didn't hear you coming in.
0:05:51 > 0:05:54Oh, and you brought your talking lizard thing with you.
0:05:54 > 0:05:56Hello, you freak of nature.
0:05:56 > 0:06:00He's in disguise. He thinks that cactus eating
0:06:00 > 0:06:03- monsters are trying to get him. - Oh, that's a shame.
0:06:03 > 0:06:04Danielle,
0:06:04 > 0:06:07we're trying to find out what electricity is and how it works.
0:06:07 > 0:06:10Everything in the universe is made of molecules.
0:06:10 > 0:06:13Even handbags and footballs and puppies.
0:06:13 > 0:06:16The molecules are made of something even smaller called atoms.
0:06:16 > 0:06:21Atoms have a nucleus with lots of electrons floating around it.
0:06:21 > 0:06:24An electron is a teeny tiny particle
0:06:24 > 0:06:28that's so small that it doesn't actually take up any space, it's
0:06:28 > 0:06:30almost like it's not there at all.
0:06:30 > 0:06:33Each electron has a tiny electric charge.
0:06:33 > 0:06:36Cos electrons are not stuck together
0:06:36 > 0:06:39they can move from one atom to another.
0:06:39 > 0:06:41When electrons flow continuously
0:06:41 > 0:06:44from atom to atom, this is called electricity.
0:06:44 > 0:06:49Oh, that reminds me, Ed, would you like to try this new nail varnish?
0:06:49 > 0:06:52It's called electric silver, it would really suit your skin tone.
0:06:52 > 0:06:54Er, no, thanks, I don't wear make-up.
0:06:54 > 0:06:57Yes, you do. I can see you're wearing tinted moisturiser.
0:06:57 > 0:07:00- Actually, you haven't blended it very well.- Ha-ha. Ha-ha.
0:07:00 > 0:07:04Anyway, anyway, back to electricity.
0:07:04 > 0:07:06OK, so we need to find something for the electronics to travel on
0:07:06 > 0:07:08in a constant stream.
0:07:08 > 0:07:14- But what?- Look at this hairdryer, right? Inside this plastic coating
0:07:14 > 0:07:16are loads of wires made of metal.
0:07:16 > 0:07:19When I power up this, the electrons come from the power source
0:07:19 > 0:07:25along these wires across a stream of atoms into the hairdryer,
0:07:25 > 0:07:28giving it the electricity I need to blow-dry my hair.
0:07:28 > 0:07:31Or the hair of a football or a puppy.
0:07:31 > 0:07:35When I turn it off this stops the stream so the electrons can't flow
0:07:35 > 0:07:38- so they're not creating electricity. - Thanks, Danielle.
0:07:42 > 0:07:45Hello, Huddersfield.
0:07:47 > 0:07:48Hat, is it?
0:07:48 > 0:07:50- Yo, dey. Mm-hm.- Monster avoiding hat?
0:07:50 > 0:07:55Yeah, he'll never see you, you're virtually invisible, aren't you?
0:07:55 > 0:07:57- Ha-ha.- While you've have been hatting yourself up,
0:07:57 > 0:07:59look what I've done, I've made Chloe's Choccy-oke.
0:07:59 > 0:08:02- Oh. Wow.- Yeah, it hasn't got everything she wanted, really,
0:08:02 > 0:08:04but I'm sure she'll be happy with it.
0:08:04 > 0:08:07What with the credit crunch and everything.
0:08:07 > 0:08:08Lupus crunch.
0:08:08 > 0:08:11- Ha-ha-ha. - More like the monster crunch?
0:08:11 > 0:08:13Yes, yes, great joke.
0:08:13 > 0:08:16Makes perfect sense, boom-boom.
0:08:16 > 0:08:18Chloe!
0:08:18 > 0:08:21- Hi, Ed. Hi, Oucho.- Hellos.
0:08:21 > 0:08:22- Hello, there.- Hi.
0:08:22 > 0:08:26Now, just ignore him, he's in disguise.
0:08:26 > 0:08:31Behold with your childlike eyes your Choccy-oke.
0:08:31 > 0:08:33- It's rubbish. - Whoa, whoa, whoa, whoa.
0:08:33 > 0:08:36She jumped in a bit quick there. Everyone's a critic.
0:08:36 > 0:08:38Come down, have a look.
0:08:38 > 0:08:41You will find it has absolutely everything you wanted.
0:08:41 > 0:08:43You wanted to make chocolate marshmallows.
0:08:43 > 0:08:46Well, you can, you've got a chocolate fountain.
0:08:46 > 0:08:48So you can dip them in there, that's the conveyor belt,
0:08:48 > 0:08:51they can all run along that. And what's this?
0:08:51 > 0:08:53- A microphone.- Yeah, for karaoke so you can sing
0:08:53 > 0:08:57Katie Perry songs. # You're hot and your cold, you do something else...
0:08:57 > 0:09:01# You're beans and you're toast. # See?
0:09:01 > 0:09:02It doesn't move.
0:09:02 > 0:09:05No, it does move, because it is on wheels, you see like that,
0:09:05 > 0:09:07so you can move it around.
0:09:07 > 0:09:09- Ed, they're roller-skates. - Well, it doesn't matter, does it?
0:09:09 > 0:09:11You wanted it to move, it moves.
0:09:11 > 0:09:15- What else don't you like about it? - It's plugged in.- Yes, yes, yes.
0:09:15 > 0:09:18Electricity comes from plugs.
0:09:18 > 0:09:22It's not going to work.
0:09:22 > 0:09:25It does work, you can move it around all you like, you see.
0:09:25 > 0:09:29Oh, dear. Lucky it wasn't switched on.
0:09:29 > 0:09:31Maybe plugs aren't such a good idea after all.
0:09:31 > 0:09:34We need electricity that can move.
0:09:34 > 0:09:37Yeah, you're right, but what though? We need to have a think.
0:09:40 > 0:09:44- Ah, Ed.- Oucho, keep it down, will you?- Ed. Ed.
0:09:44 > 0:09:46- Lupus. Ed.- Oucho, look, we're trying to have a think.
0:09:46 > 0:09:50- We're trying to sort out a very important problem.- Oh, oh. Argh.
0:09:50 > 0:09:54I don't know what to do, if only there was someone we could ask.
0:09:54 > 0:09:57Oucho.
0:09:57 > 0:10:00You are a naughty, naughty little cactus.
0:10:03 > 0:10:06You're not an innocent bystander in a hat.
0:10:06 > 0:10:09The only person stupid enough to be fooled by that stupid hat would have
0:10:09 > 0:10:12to be the winner of the world's most stupid competition for very stupid
0:10:12 > 0:10:14- people!- Rights for potatoes! Rights for potatoes!
0:10:14 > 0:10:17- Now, what's that noise? - Rights for potatoes!
0:10:17 > 0:10:19Oi, Tree-man.
0:10:19 > 0:10:21Actually, I'm an environmentalist.
0:10:21 > 0:10:24- But Treeman will do.- Would you mind keeping the noise down?
0:10:24 > 0:10:27- We're trying to find out how electricity works.- Wait, wait.
0:10:27 > 0:10:32Before you go any further, are you a friend of the potatoes?
0:10:32 > 0:10:35Oh, yeah, yeah, yeah. I love potatoes. Potato crisps, yummy.
0:10:35 > 0:10:39- What?- I, I mean, the bags. I collect the bags.
0:10:39 > 0:10:43In fact, I protect potatoes. Yeah, potatoes, brilliant.
0:10:43 > 0:10:45Good. Yeah.
0:10:45 > 0:10:48Cos, potatoes are people too, you know?
0:10:48 > 0:10:50Well, technically, they're potatoes.
0:10:50 > 0:10:53Anyway, I'll leave you to it.
0:10:53 > 0:10:55I'm trying to find out how batteries work.
0:10:55 > 0:10:57Probably not your thing, toxins.
0:10:57 > 0:11:00Oh, yeah, yeah. That's right. I do hate toxins.
0:11:00 > 0:11:03If you hate batteries so much, how are you powering those light bulbs?
0:11:03 > 0:11:09Ah. Well. Instead of using nasty chemical batteries, I use natural
0:11:09 > 0:11:11acid to create a chemical reaction.
0:11:11 > 0:11:14And all from this,
0:11:14 > 0:11:17the simple lemon.
0:11:17 > 0:11:20Right. A lemon-powered battery.
0:11:20 > 0:11:22- Brilliant. - You can mock all you like.
0:11:22 > 0:11:26But the principle of a lemon battery is the same as any other battery.
0:11:26 > 0:11:29A lemon battery is essentially a lemon with two pieces of metal
0:11:29 > 0:11:33stuck in it. It just uses lemon juice, or citric acid
0:11:33 > 0:11:36to create the chemical reaction between two metals.
0:11:36 > 0:11:39One of the pieces of metal is made from copper.
0:11:39 > 0:11:42And the other piece of metal is made from zinc.
0:11:42 > 0:11:47What happens, is that the citric acid reacts with the copper.
0:11:47 > 0:11:49It takes away some of the electrons.
0:11:49 > 0:11:54The citric acid also reacts with the zinc, but it gives it electrons.
0:11:54 > 0:11:59So what you get is zinc, with tons of electrons,
0:11:59 > 0:12:01and some copper, with not very many.
0:12:01 > 0:12:04If you put a wire between the copper
0:12:04 > 0:12:08and the zinc, then all the extra electrons on the zinc
0:12:08 > 0:12:12travel along the wire to the copper, where there are not that many.
0:12:12 > 0:12:16This creates electricity and lights up those light bulbs.
0:12:16 > 0:12:19- Oh, yeah.- Actually, you couldn't help me, could you?
0:12:19 > 0:12:21Because I'm trying to power my entire house with lemons.
0:12:21 > 0:12:24It's going to take about 3 million lemons to power it for a week.
0:12:24 > 0:12:27Where are you going to get all those lemons from?
0:12:27 > 0:12:31Ah, well. I'm going to cut down every single lemon tree in Europe.
0:12:31 > 0:12:34And if that doesn't provide enough power, then I'm going to move on
0:12:34 > 0:12:36to Asia. There are loads of lemon trees there.
0:12:36 > 0:12:42Much more environmentally friendly than nasty, chemical batteries.
0:12:42 > 0:12:43Chop down the lemon trees!
0:12:43 > 0:12:47- I've had a brilliant idea with no help from anybody else.- Oh, wow!
0:12:47 > 0:12:50We're going to use batteries to power your Choccy-oke.
0:12:50 > 0:12:53- Yeah!- It's obvious, isn't it?
0:12:53 > 0:12:54- Yes.- Where's Oucho gone?
0:12:54 > 0:12:58- There.- Oh, I didn't recognise you, it must be the hat.- Ha ha!
0:12:58 > 0:13:00Let's build this thing!
0:13:09 > 0:13:10Good work, team.
0:13:10 > 0:13:12This is really coming together.
0:13:12 > 0:13:14Oucho, stop trying to eat Chloe's fingers. We're going
0:13:14 > 0:13:16to have chocolate-covered marshmallows to eat soon.
0:13:16 > 0:13:19Let's have a recap about how this works.
0:13:19 > 0:13:23The marshmallows go in the melted chocolate, set on this tray.
0:13:23 > 0:13:25Then you pot them on that conveyor belt.
0:13:25 > 0:13:28Now, can we please start making some chocolate-covered marshmallows?
0:13:37 > 0:13:39Er, they're stuck.
0:13:39 > 0:13:41They're stuck, Ed.
0:13:41 > 0:13:44This is no good. How are we going to make all these
0:13:44 > 0:13:46chocolate-covered marshmallows, if we can't get them off the trays?
0:13:46 > 0:13:48They're stuck on.
0:13:48 > 0:13:51We got a problem here. We've faced some problems in our time,
0:13:51 > 0:13:53- but this is one of the biggest. - PHONE RINGS
0:13:55 > 0:13:57I wonder who that could be?
0:13:59 > 0:14:01Hello?
0:14:01 > 0:14:03It's the big big cheese.
0:14:03 > 0:14:06Oh, boss. You rang at just the right time, actually, because
0:14:06 > 0:14:08we're just enjoying some lovely
0:14:08 > 0:14:10chocolate-covered marshmallows with Chloe, aren't we?
0:14:10 > 0:14:13- Yes, yes. - Yes. Mmm, yum yum yum yum yum. No.
0:14:13 > 0:14:15No no no, we're not lying. Obviously not.
0:14:15 > 0:14:19Yes, yes, yes, I know it's against BBC policy to lie. Yes.
0:14:19 > 0:14:21Well, you see, the thing is...
0:14:24 > 0:14:26sorry, I'm losing the signal. Bye!
0:14:28 > 0:14:31This is serious. We could get the sack.
0:14:33 > 0:14:36The cactus eating monsters again, I thought we'd forgotten about that.
0:14:36 > 0:14:38No, No. They're still around.
0:14:38 > 0:14:41Yes, yes. How very realistic!
0:14:41 > 0:14:47Ed, we need to find a way to stop the chocolate sticking.
0:14:47 > 0:14:51You know how to make things not stick? You can't even speak English.
0:14:53 > 0:14:57You used to know Marc Gregoire?
0:14:57 > 0:15:00He invented non-stick materials, really?
0:15:02 > 0:15:05Ahh, zis washing up is ridiculous.
0:15:05 > 0:15:11Three hours. Three French hours I've spent scrubbing zees pans.
0:15:11 > 0:15:15Will they ever be clean of the food that's stuck to them?
0:15:15 > 0:15:18Non. Non, I cry.
0:15:18 > 0:15:20And, look at my petite hands.
0:15:20 > 0:15:22They're ruined, I say.
0:15:26 > 0:15:30At least I have you, my beautiful wife.
0:15:30 > 0:15:32Madame Archer Teabaguette.
0:15:32 > 0:15:35I love you. Je t'aime.
0:15:35 > 0:15:38Je t'aime. Oui, je t'aime.
0:15:38 > 0:15:40But what is this?
0:15:44 > 0:15:49It is polytetrafluoroethene? And you made this?
0:15:51 > 0:15:54Why are you wasting French hours like zis?
0:15:54 > 0:15:58When I have all zis work to do.
0:15:58 > 0:16:02Zut alors! Oh, my giddy apple tower,
0:16:02 > 0:16:05you have used it to make this non-stick pan!
0:16:05 > 0:16:08Oh, Arc de Triomphe!
0:16:08 > 0:16:13Now, I no longer have to spend five hours doing the washing up!
0:16:13 > 0:16:20Zis is ze greatest use of French hours in all ze history of France.
0:16:22 > 0:16:27Maybe the non-stick floor was not such a good idea though, my love.
0:16:27 > 0:16:32Aaaahhh, my French leg.
0:16:32 > 0:16:35OUCHO WAFFLES
0:16:35 > 0:16:38And he was hospitalised for months?
0:16:38 > 0:16:41So, you invented non-stick materials?
0:16:41 > 0:16:43When you were a French woman?
0:16:44 > 0:16:46We sound like we don't believe you?
0:16:46 > 0:16:49Really? You big liar.
0:16:49 > 0:16:51It was a lie though, wasn't it?
0:16:53 > 0:16:56Although, France, cooking.
0:16:56 > 0:16:59We could ask Monsieur Pamplemousse, the French chef.
0:16:59 > 0:17:02He knows about that sort of thing. Give him a ring.
0:17:02 > 0:17:04Oh, yeah, you don't speak English.
0:17:11 > 0:17:12Bonjour?
0:17:12 > 0:17:15It is I, Monsieur Pamplemousse.
0:17:15 > 0:17:17Oh, hello.
0:17:17 > 0:17:21Ah, it is Ed Petrie, you horse-faced buffoon.
0:17:21 > 0:17:24Why are you phoning me when we're trying to prepare ze dinner?
0:17:24 > 0:17:27I'm going to be quick, actually.
0:17:27 > 0:17:30We're trying to make chocolate-covered marshmallows.
0:17:30 > 0:17:33And, the trouble is, when the chocolate is drying,
0:17:33 > 0:17:35it sticks to the trays.
0:17:35 > 0:17:38So we need to find something to make it not stick.
0:17:38 > 0:17:42Goodness me, you sports-obsessed English person. Why is he allowed on
0:17:42 > 0:17:45ze television, whilst I'm banned from all major Freeview channels?
0:17:45 > 0:17:49The reason ze chocolate is sticking
0:17:49 > 0:17:52is because of ze electrons, you fool!
0:17:52 > 0:17:54It's electrons again, stupid electrons.
0:17:54 > 0:17:57What school did you go to?
0:17:57 > 0:18:00The school for people with no brain or something?
0:18:00 > 0:18:05Don't you know that everything has electrons?
0:18:05 > 0:18:10Ze chocolate and ze surface of the trays are sharing ze electrons.
0:18:10 > 0:18:13And zis is causing them to stick together.
0:18:13 > 0:18:16It's a bit like, um,
0:18:16 > 0:18:21two English idiots holding on to ze same rolling pin.
0:18:21 > 0:18:26As long as they're holding ze rolling pin, they cannot move.
0:18:26 > 0:18:29But, if they let go of ze rolling pin,
0:18:30 > 0:18:33they can move around.
0:18:33 > 0:18:35Because they're no longer stuck together.
0:18:35 > 0:18:38So, should we find a surface that chocolate
0:18:38 > 0:18:39won't share its electrons with?
0:18:39 > 0:18:43Do you want an award for being a total fool?
0:18:43 > 0:18:47Just find a surface that won't share its electrons with ze chocolate.
0:18:47 > 0:18:49It's not difficult.
0:18:49 > 0:18:53Cooks are always using non-stick surfaces in their cooking.
0:18:53 > 0:18:56Oui? It's not difficult!
0:18:56 > 0:18:59- Like what?- I have not got any more time to waste with you.
0:18:59 > 0:19:02I'm preparing a soup for ze French ambassador,
0:19:02 > 0:19:07using the finest meats in all of Europe.
0:19:07 > 0:19:10Starting with, um,
0:19:10 > 0:19:12ze turkey.
0:19:12 > 0:19:15Come here, turkey chef. Prepare to be plucked!
0:19:19 > 0:19:24Sorry to interrupt. Guys, I've just found out that certain substances
0:19:24 > 0:19:26share their electrons, right?
0:19:26 > 0:19:28So, if we want to make sure that our chocolate doesn't stick,
0:19:28 > 0:19:31we need to find a surface that won't share its electrons with it.
0:19:31 > 0:19:34What we need is some kind of Chocolate Sticking Testing Machine.
0:19:34 > 0:19:38Oh, yeah, there was a delivery for you while you were on the phone.
0:19:38 > 0:19:41Oh. A Chocolate Sticking Testing Machine.
0:19:42 > 0:19:44- Who sent that?- Da's brob Tirry!
0:19:44 > 0:19:47- From Terry?- From Terry?
0:19:47 > 0:19:49- Who's he?- Don't ask.
0:19:49 > 0:19:52Well, let's get testing!
0:19:52 > 0:19:55So, we need to find out which surfaces the chocolate sticks to and
0:19:55 > 0:19:57which are non-stick.
0:19:57 > 0:20:00Got this, a high-tech gun, here.
0:20:00 > 0:20:03Let's have a look at the instructions. Step one.
0:20:03 > 0:20:07Fill the firing arm with warm chocolate but remember to check it's
0:20:07 > 0:20:11not too hot. No, not stick my finger in it to check the temperature.
0:20:11 > 0:20:14I might burn my finger. These are my TV hands.
0:20:14 > 0:20:18I think a thermometer's probably more sensible, don't you?
0:20:20 > 0:20:22That's not going to burn anyone. Excellent.
0:20:22 > 0:20:23Step two.
0:20:23 > 0:20:25Shoot chocolate at the target.
0:20:25 > 0:20:28That's going to be you, then, because it requires a lot of
0:20:28 > 0:20:31running around and you're younger than me. Step three.
0:20:31 > 0:20:35Leave chocolate on the targets to set for a while. Two hours?
0:20:35 > 0:20:39Waiting around. These are the surfaces.
0:20:39 > 0:20:41- What's that?- Cardboard.
0:20:41 > 0:20:43They make food packaging out of that, don't they?
0:20:43 > 0:20:45That could work. That looks like felt.
0:20:45 > 0:20:49I don't think that'll be very good, but you never know.
0:20:49 > 0:20:52- That is... what's that? - It's plastic.
0:20:52 > 0:20:54Oh, it's plastic. Yes. My lunchbox is made out of that.
0:20:54 > 0:20:56That could be good.
0:20:56 > 0:20:59And this looks like... Yeah, it's greaseproof paper. My dad
0:20:59 > 0:21:03wraps his sandwiches in that. OK. Which one do you want to start with?
0:21:03 > 0:21:05- The felt.- Felt.
0:21:05 > 0:21:07Let's go.
0:21:07 > 0:21:10Here we go. Are you ready?
0:21:10 > 0:21:14- Yes.- Here we go.
0:21:14 > 0:21:16Sorry, I got you in the eye.
0:21:16 > 0:21:19That's enough of that one.
0:21:19 > 0:21:20OK.
0:21:20 > 0:21:23Just let the felt dry.
0:21:23 > 0:21:26- So, which one do you want to move on to?- Greaseproof paper.
0:21:26 > 0:21:28I love my job.
0:21:28 > 0:21:30Right, here we go.
0:21:30 > 0:21:33Go left. Left, left. No, sorry right, right.
0:21:33 > 0:21:35No, sorry. Just stay... Oh, dear.
0:21:35 > 0:21:37Good. That's the greaseproof paper done.
0:21:37 > 0:21:39What should we move on to?
0:21:39 > 0:21:41- Cardboard.- To the right.
0:21:41 > 0:21:45I think we should take this down the Tate Gallery.
0:21:45 > 0:21:46We would make a fortune.
0:21:46 > 0:21:49Chocolatey, really, do you think?
0:21:49 > 0:21:52It's quite nice. Just the plastic left, Chloe.
0:21:55 > 0:21:57- Last one.- Last one?
0:21:57 > 0:21:59- Yes.- Yes, it's the last one. There we go. All finished.
0:21:59 > 0:22:02- All done.- You're just saying that.
0:22:02 > 0:22:04No, it is, honestly. Look, look!
0:22:04 > 0:22:06I've got this hat for you.
0:22:06 > 0:22:10There you go. What have I done? I haven't done anything to you.
0:22:10 > 0:22:12What are you doing?
0:22:12 > 0:22:14I think it's set now.
0:22:14 > 0:22:18OK, let's find out which is the best non-stick material.
0:22:18 > 0:22:20So this was the felt.
0:22:20 > 0:22:22Oh, dear.
0:22:23 > 0:22:26- It's stuck good and proper, that, isn't it?- Yep.
0:22:26 > 0:22:28Right, that's no good.
0:22:30 > 0:22:31Plastic.
0:22:36 > 0:22:38Well, it's all right, isn't it?
0:22:38 > 0:22:40It's pretty good.
0:22:40 > 0:22:42It's a bit hard.
0:22:42 > 0:22:44It takes a bit of peeling.
0:22:44 > 0:22:46It's a maybe with the plastic.
0:22:46 > 0:22:48Cardboard.
0:22:51 > 0:22:53Oh, no. No. That's no good at all.
0:22:53 > 0:22:56Do you fancy
0:22:56 > 0:23:00a bit of chocolate? I was worried you might not have enough on you.
0:23:00 > 0:23:02This is the last one, then.
0:23:02 > 0:23:04Greaseproof paper.
0:23:06 > 0:23:09Oh, wow, look at that.
0:23:09 > 0:23:11It's nearly all come off.
0:23:12 > 0:23:14So, what do you think we should use, then?
0:23:14 > 0:23:17- Greaseproof paper.- Yeah.
0:23:17 > 0:23:19OK. Let's line our trays for the conveyor belt with
0:23:19 > 0:23:21greaseproof paper. Brilliant.
0:23:21 > 0:23:23No, no, no!
0:23:23 > 0:23:25Oucho, I told you there's no such thing as monsters.
0:23:27 > 0:23:31THEY SCREAM
0:23:42 > 0:23:46# This week, we chose Chloe's cool Choccy-oke
0:23:46 > 0:23:50# One look at the design and we both said, okey-dokey
0:23:50 > 0:23:55# It looked pretty tricky, we had to find a way
0:23:55 > 0:23:58# If only to keep cactus eating monsters at bay
0:23:58 > 0:24:02# Power was required to run the conveyor belt
0:24:02 > 0:24:05# Danielle filled us in, she made Oucho's heart melt
0:24:05 > 0:24:08# I knocked up a version
0:24:08 > 0:24:12# But like a proper mug, I forgot it should be portable
0:24:12 > 0:24:14# I'd included a plug
0:24:14 > 0:24:16# Batteries
0:24:16 > 0:24:19# That is what we need, man, we had a quick look at a lemon one
0:24:19 > 0:24:22# Made by Paul the Treeman
0:24:22 > 0:24:23# Batteries
0:24:23 > 0:24:25# Electrons moving about
0:24:25 > 0:24:30# Sticking batteries in the Choccy-oke was clearly a pretty good shout
0:24:33 > 0:24:37# With batteries installed, we finally had power
0:24:37 > 0:24:41# Though waiting for the chocolate to set, it takes several hours
0:24:41 > 0:24:45# But once it had gone hard, it was stuck to the conveyor
0:24:45 > 0:24:49# We needed something non-stick or we hadn't got a prayer
0:24:49 > 0:24:53# In the absence of polytetrafluoroethylene
0:24:53 > 0:24:57# Oucho had got hold of the non-stick testing machine
0:24:57 > 0:24:59# We sprayed warm chocolate and then
0:24:59 > 0:25:05# Let it set on surfaces to see if they would share their electrons
0:25:05 > 0:25:07# Non-stick
0:25:07 > 0:25:09# What surface would be best?
0:25:09 > 0:25:13# Cardboard, plastic, and felt, well, they all failed the test
0:25:13 > 0:25:15# Non-stick
0:25:15 > 0:25:19# So, for our conveyor, turns out if we don't want stuff to stick
0:25:19 > 0:25:22# We best used greaseproof paper. #
0:25:22 > 0:25:24Ha ha ha ha ha ha ha ha ha ha ha ha ha.
0:25:24 > 0:25:27Well, we've come a long way with this Choccy-oke, haven't we?
0:25:27 > 0:25:31We've learnt all about batteries, non-stick surfaces.
0:25:31 > 0:25:33Ah. Non-stick surfaces.
0:25:36 > 0:25:41Oucho nearly got eaten by monsters, as well. All right, we'll hurry.
0:25:41 > 0:25:43- Should we show everyone at home? - Yep.
0:25:43 > 0:25:45Chloe asked us for a Choccy-oke, that made
0:25:45 > 0:25:50chocolate-covered marshmallows and had a built-in karaoke machine.
0:25:50 > 0:25:52And here it is!
0:25:53 > 0:25:57Not really. You see, you thought that would be it, didn't you?
0:25:57 > 0:25:59- Ed. It's not funny. - Oh, come on, it is.
0:25:59 > 0:26:02That joke is a gift that keeps on giving. Come on. All right.
0:26:02 > 0:26:04Here it is!
0:26:09 > 0:26:12OK, so we're all ready to go? We've got the melted chocolate,
0:26:12 > 0:26:14- and the chocolate fountain to dip the marshmallows in?- Yep.
0:26:14 > 0:26:17Got the trays lined with greaseproof paper?
0:26:17 > 0:26:18So they can dry on the conveyor belt.
0:26:18 > 0:26:21And then you are going to sell them to your friends up there.
0:26:21 > 0:26:23And sing karaoke at the same time. Microphone working?
0:26:23 > 0:26:25Yes. Hello!
0:26:25 > 0:26:26Lovely. Let's go.
0:26:26 > 0:26:31# Cos you're hot and you're cold, you're yes then you're no
0:26:31 > 0:26:34# You're in then you're out, you're up and you're down
0:26:34 > 0:26:37# You're wrong when it's right, it's black and it's white
0:26:37 > 0:26:41# We fight, we break up, we kiss, we make up. Altogether now!
0:26:41 > 0:26:45# You're hot then you're cold, you're yes then you're no
0:26:45 > 0:26:48# You're in and you're out, you're up and you're down
0:26:48 > 0:26:52# You're wrong when it's right, it's black and it's right
0:26:52 > 0:26:56# We fight, we break up, we kiss, we make up... #
0:26:56 > 0:26:59I think our work here is done, Oucho. It's the monster!
0:26:59 > 0:27:03Hubba blubba waaaaa!
0:27:03 > 0:27:05Oh, yes, if I give him Choccy-okes he'll go away.
0:27:05 > 0:27:10# You're in and you're out, you're up and you're down
0:27:10 > 0:27:14# You're wrong when it's right, it's black and it's white
0:27:14 > 0:27:18# We fight, we break up, we kiss, we make up... #
0:27:18 > 0:27:22Yeah, boss. It went really well. Listen to this.
0:27:22 > 0:27:25Everyone is eating Choccy-okes like there's no tomorrow.
0:27:25 > 0:27:29What's that? Jumping up and down and eating marshmallows at the same time
0:27:29 > 0:27:32can make children sick? Oh, dear.
0:27:37 > 0:27:39From now on, when you say that something exists,
0:27:39 > 0:27:42I'm going to believe you, mate.
0:27:42 > 0:27:44Not like fairies, they don't exist.
0:27:44 > 0:27:46Not dragons, don't be stupid.
0:27:46 > 0:27:49No, the Daleks are in Doctor Who, aren't they? The Chuckle Brothers?
0:27:49 > 0:27:52Don't be stupid. They don't exist.
0:27:52 > 0:27:54No-one that old would be on kids' TV. Think about it.
0:27:54 > 0:27:57They're animated or something.
