7:33:13 > 7:33:20.
7:33:27 > 7:33:28It may be cold outside,
7:33:28 > 7:33:31- but things are hotting up here in the Blue Peter studio.- That's right.
7:33:31 > 7:33:33Daredevil scientist Greg Foot is here,
7:33:33 > 7:33:36with food that will make you sweat, shake, and shiver.
7:33:36 > 7:33:38I find out if I have got what it takes to make it as a top spy
7:33:38 > 7:33:40- on a new series of M.I. High. - Of course you have.
7:33:40 > 7:33:43And he is tipped for big things in 2014. Elyar Fox is right here
7:33:43 > 7:33:46in the studio performing his debut single, Do It All Over Again.
7:33:46 > 7:33:49That is all coming up on today's live Blue Peter.
7:34:04 > 7:34:07CHEERING AND APPLAUSE
7:34:07 > 7:34:09ALL: Hello!
7:34:09 > 7:34:10How are you doing?
7:34:10 > 7:34:13You're watching Blue Peter, it is a live show, I'm wearing a bowtie.
7:34:13 > 7:34:15It is a special occasion. I have missed you people, I really have.
7:34:15 > 7:34:18- We have missed you. - Welcome back, Barney.
7:34:18 > 7:34:20- Thank you very much, it is good to be here.- Don't leave me hanging.
7:34:20 > 7:34:23- Sorry, didn't see that.- Awkward. You might not be smiling so much
7:34:23 > 7:34:25when you find out about the chilli challenge
7:34:25 > 7:34:27for you and Radzi at the end of the show.
7:34:27 > 7:34:29- I'm not doing that, see you later. - You are. Stay here.
7:34:29 > 7:34:32You are not going anywhere. It is happening.
7:34:32 > 7:34:35- Yes, my taste buds are literally terrified, Lindsey.- They should be.
7:34:35 > 7:34:37And later on, I will be giving you a tour
7:34:37 > 7:34:39of the brand-new series of M.I. High.
7:34:39 > 7:34:42Plus, we will be showing you some real-life spy gadgets
7:34:42 > 7:34:44- in the studio, Barney, incredible.- Can't wait.
7:34:44 > 7:34:46That's songs, spies, seriously hot chillies.
7:34:46 > 7:34:49- What's not to like about today's show?- That's true.
7:34:49 > 7:34:50- Apart from your hair.- Stop it!
7:34:50 > 7:34:52Speaking of spies, we want to know,
7:34:52 > 7:34:56if you had to design a secret spy device, what would it be, and why?
7:34:56 > 7:34:59- I would have a watch that fires some kind of disc out of it.- Oh!
7:34:59 > 7:35:01Like disc golf?
7:35:01 > 7:35:04Like the thing you did last week, yes, some sort of proper, like...
7:35:04 > 7:35:07whatever you fire it into, it then, maps the location,
7:35:07 > 7:35:10- to let others know. Something cool like that.- It's not very clear.
7:35:10 > 7:35:12You need to go away and think about your spy gadgets!
7:35:12 > 7:35:14I should have thought about it before I came on.
7:35:14 > 7:35:16I'd have a hand-held gadget, I'd press it, just disappear.
7:35:16 > 7:35:18Really nice. Whatever your ideas are, let us know.
7:35:18 > 7:35:22We are live and we want you to get involved.
7:35:22 > 7:35:25- We love when you get in touch. - We do love when you get in touch.
7:35:25 > 7:35:27So much so that like a proud parent with a big fridge,
7:35:27 > 7:35:30- we stick your stuff up on our big badge wall over here.- Stop it!
7:35:30 > 7:35:33I got a onesie for Christmas, I am genuinely the most excited
7:35:33 > 7:35:36I have been. I haven't worn onesies before, and I am loving it.
7:35:36 > 7:35:39Abigail knew this, she sensed it, in the Christmas spirit,
7:35:39 > 7:35:43and she has designed onesies for you and me, and...whoever else is here!
7:35:43 > 7:35:47- These two are being so annoying today.- I have missed being here.
7:35:47 > 7:35:51Don't give me a live TV show, because it is going to go...brilliantly.
7:35:51 > 7:35:54Right, so there you go. Bob skeleton and a radio there.
7:35:54 > 7:35:56This is Radzi's onesie,
7:35:56 > 7:35:58and then you have got Lindsey's onesie at the back,
7:35:58 > 7:36:01which has got musical notes on it, and lots of flags.
7:36:01 > 7:36:03Because we know you like flags.
7:36:03 > 7:36:05I like languages, that is why that is there.
7:36:05 > 7:36:09And my onesie has got Radzi gunged on the sleeve,
7:36:09 > 7:36:13- and Lindsey in my armpit. - Oh, lovely!- That is the pits.
7:36:13 > 7:36:17- Lucky me.- Oh! Don't leave me hanging!- Take two!
7:36:17 > 7:36:19This is from Chloe.
7:36:19 > 7:36:22We were at the big badge wall. This is the big badge book.
7:36:22 > 7:36:26And if you look inside, it has got all the Blue Peter badges.
7:36:26 > 7:36:29The orange one, the purple one, the sports one, the silver one,
7:36:29 > 7:36:31but the most important one, the gold one!
7:36:31 > 7:36:33- We all want the gold one.- Oh, yes.
7:36:33 > 7:36:35And it's not just post and e-mails you have been sending in.
7:36:35 > 7:36:38Check this out, it is from Jasmine and Harry from Buckinghamshire.
7:36:38 > 7:36:41And they have changed the Blue Peter theme
7:36:41 > 7:36:42into a jazzy song called Blues Peter.
7:36:42 > 7:36:45Very good. We absolutely love this.
7:36:45 > 7:36:47Their grandad filmed it, and best of all,
7:36:47 > 7:36:50it is on my favourite instrument, the saxophone. Take a look at this.
7:36:50 > 7:36:54JAZZY BLUE PETER THEME
7:37:04 > 7:37:07CHEERING AND APPLAUSE
7:37:07 > 7:37:09- Take a bow, guys. - So good.- Absolutely brilliant.
7:37:09 > 7:37:12I love that Jasmine's name is actually jazz-min.
7:37:12 > 7:37:14- How cool does that look? Brilliant, thanks very much.- I like that.
7:37:14 > 7:37:17Now, we know you love it when we go behind the scenes.
7:37:17 > 7:37:19So when I got the chance to do just that at the brand-new
7:37:19 > 7:37:23series of M.I. High, I jumped at the chance. You are going to love this.
7:37:23 > 7:37:27Linds, Barney, four words for you. Oh, yeah? Spy in the making.
7:37:36 > 7:37:38Today is a very exciting day.
7:37:38 > 7:37:41I am set for a brand-new series of M.I. High.
7:37:43 > 7:37:47M.I. High is set in a school that has got a top secret.
7:37:47 > 7:37:49There are more than just teachers and pupils here, and it is not
7:37:49 > 7:37:52just their homework that MI9 agents are battling with.
7:37:55 > 7:38:00So, here I am at the M.I. High spy base. How cool is this?
7:38:00 > 7:38:02But, I have work to do.
7:38:02 > 7:38:04I am on a mission to find out what skills
7:38:04 > 7:38:07I will need to make it as a great spy.
7:38:07 > 7:38:09I wonder who I could ask.
7:38:17 > 7:38:19Sam, Oyiza and Oscar, or better known as Agent Dan,
7:38:19 > 7:38:21Agent Aneisha and Agent Tom.
7:38:21 > 7:38:24What has the new series got to offer us, do you think?
7:38:24 > 7:38:27- Are we going to see more action? - Definitely.- More baddies?
7:38:27 > 7:38:30- More baddies, more action, more fighting.- More saving the world?
7:38:30 > 7:38:32More saving the world.
7:38:32 > 7:38:34What are your characters' strongest skills, do you think?
7:38:34 > 7:38:36Practicality in the field.
7:38:36 > 7:38:39Not too much into the technical side of things
7:38:39 > 7:38:42as much as he is going out there and doing it.
7:38:42 > 7:38:45Aneisha joined as the master of disguise, so she can tell
7:38:45 > 7:38:48when something's not right. She's really good at reading people.
7:38:48 > 7:38:51Tom is an electronics genius.
7:38:51 > 7:38:54Really, he's the main one, to be honest.
7:38:54 > 7:38:58- He's modest, as well, isn't he? - Very modest! Very handsome!
7:38:59 > 7:39:01I'd love to be a spy.
7:39:01 > 7:39:04- We've got some challenges. Are you up for it?- ALL: Yes.
7:39:04 > 7:39:07That's what I'm talking about. The first one is on the screen.
7:39:07 > 7:39:09Radzi, I hear you want to be a spy.
7:39:09 > 7:39:14You're going to have to be able to crack codes. In the following story, there is a coded message. Crack it.
7:39:14 > 7:39:15'So the spy master is saying'
7:39:15 > 7:39:19somewhere in the text on the screen there is a hidden message.
7:39:19 > 7:39:21'The answer is in there somewhere.'
7:39:21 > 7:39:24- What are our thoughts, guys? - I have no idea.
7:39:24 > 7:39:29You kind of think it's going to be like the first letter of one word and the second letter.
7:39:29 > 7:39:36Oh, OK, go on. What about if it was the last letter of a sentence? T-Y-Y.
7:39:36 > 7:39:38That doesn't make sense. We've got to get this.
7:39:38 > 7:39:41- Is intelligence important to being a spy?- Apparently not!
7:39:41 > 7:39:43LAUGHTER
7:39:43 > 7:39:48- Um...- What if it was the first letter in a sentence?
7:39:48 > 7:39:50Blue Peter love...
7:39:50 > 7:39:52- S...- Loves.
7:39:52 > 7:39:56- M-I... - Oh, we all know what it's going to be.
7:39:56 > 7:39:59- What are we thinking? - Blue Peter loves M.I. High.
7:39:59 > 7:40:01- That's sweet, that.- High-five!
7:40:01 > 7:40:04'Code cracked. Mission one complete.'
7:40:04 > 7:40:06Boom! Job done.
7:40:06 > 7:40:08Radzi, you did better than I expected,
7:40:08 > 7:40:11although I'm not sure how you would have coped without my team.
7:40:11 > 7:40:13All agents need to be able to solve problems.
7:40:13 > 7:40:17I have two water carriers, one of five litres and one of three.
7:40:17 > 7:40:20You need to fill one of them with four litres of water.
7:40:20 > 7:40:23Use as much water as you like and good luck.
7:40:23 > 7:40:25How are going to do it?
7:40:25 > 7:40:26'This one is tricky.'
7:40:26 > 7:40:30Exactly four litres from three- and five-litre bottles
7:40:30 > 7:40:31without a four-litre bottle.
7:40:31 > 7:40:35'We've got some serious spy sums to do to get this one right.'
7:40:35 > 7:40:38What now? 'How would you do it?'
7:40:38 > 7:40:41That is better. Smart.
7:40:41 > 7:40:44Oh, no! It's gone pear-shaped.
7:40:44 > 7:40:45I've got it, I've got it, I've got it.
7:40:45 > 7:40:47- No, no, no.- Stop, stop, stop.
7:40:47 > 7:40:52- You put one litre from here into there. Fill it with three litres. - Yes!- Wa-hey!
7:40:52 > 7:40:55- Done.- Yes! OK.
7:40:56 > 7:40:58'Mission two complete.' Job done.
7:40:58 > 7:40:59'Training is going well,'
7:40:59 > 7:41:03but now it's time to get some top tips from M.I. High's newest recruit.
7:41:03 > 7:41:07'Julia plays Keri, a quick-learning high-kicking super-spying agent.'
7:41:07 > 7:41:12- What can you tell us about Keri? - Well, there's lots of secrets to Keri, so I can't say much.
7:41:12 > 7:41:16She is extremely friendly, bubbly and a bit ditzy!
7:41:16 > 7:41:19Like yourself, I'd like to be a spy. Have I got what it takes?
7:41:19 > 7:41:20I think you definitely do.
7:41:20 > 7:41:22If you just pick up the sneaking-around skills,
7:41:22 > 7:41:24I think you'll be all right.
7:41:24 > 7:41:27'So, I've disguised myself as the janitor.'
7:41:29 > 7:41:32All right, so yellow is a bit bright to blend in,
7:41:32 > 7:41:34but everyone's too busy filming today, anyway,
7:41:34 > 7:41:37and that means I can get an exclusive behind-the-scenes look
7:41:37 > 7:41:39at the new series.
7:41:40 > 7:41:42Once again, the school is under threat
7:41:42 > 7:41:44and it's only MI9 standing in the way.
7:41:49 > 7:41:51They did not look too friendly.
7:41:53 > 7:41:55Uh-oh. We've got company.
7:42:00 > 7:42:01And action.
7:42:14 > 7:42:17And that is what happens when you mess with spies.
7:42:19 > 7:42:21What a day that was.
7:42:21 > 7:42:25Thank you so much everybody at M.I. High. Their series has started.
7:42:25 > 7:42:29You can catch it on CBBC every single Monday at 5:30.
7:42:29 > 7:42:33If you did miss the first episode, go on to CBBC iPlayer.
7:42:33 > 7:42:34Plus, when I was filming,
7:42:34 > 7:42:37I also filmed an exclusive backstage diary
7:42:37 > 7:42:39and if you want to see that,
7:42:39 > 7:42:43go onto the Blue Peter website and click Blue Peter backstage.
7:42:43 > 7:42:46Many of the spy gadgets you see in films
7:42:46 > 7:42:48or on TV programmes are inspired by the real thing
7:42:48 > 7:42:52and we've been lucky enough to have them in the studio.
7:42:52 > 7:42:55Everyone knows I love gadgets and, up until today, I thought I'd seen
7:42:55 > 7:42:58pretty much all there was to see, but I'm wrong.
7:42:58 > 7:43:02This is Mandy Mason, a curator at the Imperial War Museum. Hi.
7:43:02 > 7:43:05What have you brought? It's intriguing. It is nothing I've seen before.
7:43:05 > 7:43:08- What is this down here? - This little thing is a camera.
7:43:08 > 7:43:13It's a very tiny camera made during the Second World War by Kodak
7:43:13 > 7:43:18and they were making these miniature cameras for the use of spies, secret agents.
7:43:18 > 7:43:20They are called matchbox cameras.
7:43:20 > 7:43:22When spies were sent out with these cameras, they were given
7:43:22 > 7:43:26special covers so it would look just like a matchbox.
7:43:26 > 7:43:30They were given different covers and designs, depending on which country they were spying in.
7:43:30 > 7:43:32It's very clever. Was this actually used?
7:43:32 > 7:43:35This one was used by an American spy at the end of the war.
7:43:35 > 7:43:38Camouflage is a very important thing if you're a spy.
7:43:38 > 7:43:40You don't want people to know you or your gadgets are there.
7:43:40 > 7:43:45They have used some pretty creative ways to hide gadgets over the years.
7:43:45 > 7:43:47Yes, they were hidden in all sorts of things.
7:43:47 > 7:43:48One of the most unusual,
7:43:48 > 7:43:53they had small explosive devices, about so big, called tyre-bursters.
7:43:53 > 7:43:59They hid these tiny explosives in animal poo, or fake animal poo, sometimes.
7:43:59 > 7:44:03So horse poo, mule poo, and they put them on roads and bridges,
7:44:03 > 7:44:06anywhere where there would be a lot of enemy traffic.
7:44:06 > 7:44:08If an enemy vehicle was to drive over one of these, the pressure
7:44:08 > 7:44:11would set off the explosive and burst the vehicle tyres,
7:44:11 > 7:44:14- basically stopping it from going anywhere. So very clever.- I love it.
7:44:14 > 7:44:16That's one of my favourite things about being a spy -
7:44:16 > 7:44:19you get gadgets and you can hide stuff in animal poo.
7:44:19 > 7:44:22Moving on, we have some feet made of rubber.
7:44:22 > 7:44:25They are a gadget and it's like nothing I've seen before
7:44:25 > 7:44:27and they are very clever, as well.
7:44:27 > 7:44:30These rubber feet were made for the use of agents operating in the Far East,
7:44:30 > 7:44:33where they might be landing on beaches in the dead of night.
7:44:33 > 7:44:36The idea was you'd strap these on under your normal shoes
7:44:36 > 7:44:39or boots and when the agents landed on the beach
7:44:39 > 7:44:41and stirred and walked, it would leave a footprint
7:44:41 > 7:44:43that would looked like a normal bare foot,
7:44:43 > 7:44:47so the sort of footprints left by somebody who is a native to that island,
7:44:47 > 7:44:50rather than a giveaway footprint of a big British Army boot.
7:44:50 > 7:44:52How clever is that? It's brilliant. I want a pair of those.
7:44:52 > 7:44:54If you are going to be a secret agent,
7:44:54 > 7:44:58you'll need a catalogue to find the devices you need to do your job.
7:44:58 > 7:45:01This is said catalogue, with lots of different things.
7:45:01 > 7:45:03One thing I spotted was the itching powder.
7:45:03 > 7:45:06Anyone who's been to a joke shop knows what that is,
7:45:06 > 7:45:08but I was surprised to see it being used by a secret agent.
7:45:08 > 7:45:11Some of the inventions were very technical and complex.
7:45:11 > 7:45:16Some were very basic so, as you say, some were given itching powder.
7:45:16 > 7:45:20The idea was you would try to put it into enemy clothes and uniforms.
7:45:20 > 7:45:24There was one account where somebody managed to put some through a laundry
7:45:24 > 7:45:27into some German submariners' uniforms.
7:45:27 > 7:45:30If you are in a submarine, you're away underwater,
7:45:30 > 7:45:33you can't change your clothes, you can't wash very easily,
7:45:33 > 7:45:36so it would be uncomfortable to have some nasty, itching painful skin.
7:45:36 > 7:45:39Is that what Mucuna is, is that the ingredient?
7:45:39 > 7:45:42Mucuna is the name of the plant and it was the seeds from this plant
7:45:42 > 7:45:44that made the really nasty itching powder they used.
7:45:44 > 7:45:46You've no idea how much fun I'm having right now.
7:45:46 > 7:45:49Gadgets and itching powder, I'm loving this. Mandy, thank so much for coming in.
7:45:49 > 7:45:52If you fancy the idea of becoming a secret agent,
7:45:52 > 7:45:54why not head to the IWM North throughout February?
7:45:54 > 7:45:56You've got lots of activities,
7:45:56 > 7:45:58so that you can try your hand at being a secret agent.
7:45:58 > 7:46:01Don't forget to give us your ideas for your spy gadgets -
7:46:01 > 7:46:05that's the Blue Peter website. Mandy, thank you very much.
7:46:05 > 7:46:08Ugh, gadgets hidden in poo, that is disgusting.
7:46:08 > 7:46:10Though kind of ingenious. I like it.
7:46:10 > 7:46:12Now, from the secrets of being a spy
7:46:12 > 7:46:14to the secrets of seriously hot food.
7:46:14 > 7:46:16We know you love growing your own vegetables.
7:46:16 > 7:46:18Have a look at this. It's from Cameron.
7:46:18 > 7:46:19He is 11, from Manchester.
7:46:19 > 7:46:22It's a photo of him in his garden, growing chillies.
7:46:22 > 7:46:24Well done, Cameron, good job.
7:46:24 > 7:46:27Speaking of chillies, I got to go to a chilli farm in the UK
7:46:27 > 7:46:30a few weeks ago and find out what makes them so fiery.
7:46:31 > 7:46:34If you've ever eaten anything hot, you know how that feels.
7:46:34 > 7:46:36But there are two different kinds of hot.
7:46:36 > 7:46:39This steaming cuppa is what we'd call hot hot,
7:46:39 > 7:46:41which means it can physically burn you.
7:46:41 > 7:46:44But the other type of heat is spicy hot
7:46:44 > 7:46:47and that comes from these little bad boys - chillies.
7:46:47 > 7:46:50Chillies have been grown and used in cooking for centuries
7:46:50 > 7:46:53and people are now finding ways to grow them hotter and hotter.
7:46:53 > 7:46:57Even though they seem exotic, loads of chillies are grown in the UK
7:46:57 > 7:47:01and Alex is one of the few farmers cultivating super-hot chillies.
7:47:01 > 7:47:04Today, I've come to meet him on his farm.
7:47:04 > 7:47:06Alex, what's the deal with these chillies,
7:47:06 > 7:47:09because they are not that hot to hold, but to taste...
7:47:09 > 7:47:14They are quite hot. Oh! That is really hot.
7:47:14 > 7:47:16My lip has gone a bit numb.
7:47:16 > 7:47:18My mouth feels like it's on fire and I feel I can want to cry.
7:47:18 > 7:47:20On the outside of the skin, there is no capsaicin.
7:47:20 > 7:47:23Capsaicin is what makes them hot, that's oil.
7:47:23 > 7:47:24It affects your pain receptors in your mouth.
7:47:24 > 7:47:27It's not physically hot, it won't burn you,
7:47:27 > 7:47:29it won't burn your skin, but it tricks your mind
7:47:29 > 7:47:31into thinking there's something very hot in your mouth.
7:47:31 > 7:47:33So it's nothing to do with the seeds,
7:47:33 > 7:47:36it's to do with the liquid in the chilli that makes it really hot?
7:47:36 > 7:47:38That's right. The seeds are heatless,
7:47:38 > 7:47:42but the hotter part of the chilli is the bit that holds the seeds in place.
7:47:42 > 7:47:44- In the middle.- The white pith stuff.
7:47:44 > 7:47:48- Actually, it's cooled off now. Shall we go find a really hot one? - Why not?
7:47:48 > 7:47:51'The amount of capsaicin in a chilli determines how hot it is.'
7:47:51 > 7:47:54We measure that on the Scoville scale.
7:47:54 > 7:47:57A chilli with a Scoville score of one means you need to add
7:47:57 > 7:47:59one drop of water to one drop of chilli extract
7:47:59 > 7:48:01before you can no longer takes the chilli.
7:48:01 > 7:48:03The scale goes all the way up to
7:48:03 > 7:48:05a tongue-torching two million Scoville units,
7:48:05 > 7:48:07which means the hottest chillies in the world
7:48:07 > 7:48:09would need two million drops of water
7:48:09 > 7:48:12before you couldn't taste just one drop of chilli extract.
7:48:12 > 7:48:15'And you'd be back to zero heat.'
7:48:15 > 7:48:17How super-spicy are these chillies?
7:48:17 > 7:48:18These 7-Pot Habaneros
7:48:18 > 7:48:21are over one million Scoville heat units.
7:48:21 > 7:48:24Just one teaspoon of extract from this chilli would take
7:48:24 > 7:48:285,000 litres of water in order to dilute it to zero heat.
7:48:28 > 7:48:33- OK, Lindsey, here is 5,000 litres of water.- That is nuts.
7:48:33 > 7:48:36So it takes this much water to cancel out
7:48:36 > 7:48:38the teaspoon of one of these chillies?
7:48:38 > 7:48:41- That's right. - So they really are very spicy?
7:48:41 > 7:48:44They are very spicy and that's why we recommend wearing gloves.
7:48:44 > 7:48:47If you got that on your finger and touched your eye, or something,
7:48:47 > 7:48:50it's not a good idea? Surely you can't use this much water
7:48:50 > 7:48:54every time you want to measure a chilli, so how is that done?
7:48:54 > 7:48:57These days, it's done totally differently, in laboratories.
7:48:57 > 7:48:58Right. Better get to the lab.
7:48:58 > 7:49:01With my extreme-strength chilli picked,
7:49:01 > 7:49:02it's time to measure exactly how hot it is,
7:49:02 > 7:49:05and no-one is better qualified than plant scientist Andrew Dukes.
7:49:05 > 7:49:08He is the man that chilli farmers send their super-hot chillies to.
7:49:08 > 7:49:11He's measured two of the hottest chillies in the world
7:49:11 > 7:49:13in the ongoing search for record breakers.
7:49:13 > 7:49:17Andy, how do we go about measuring the spiciness of this chilli?
7:49:17 > 7:49:22What we need to do is separate the chilli into its component parts.
7:49:22 > 7:49:26To do that, we use a process called liquid chromatography.
7:49:26 > 7:49:28That might sound science-y,
7:49:28 > 7:49:31but, actually, it's a way of using liquid to separate
7:49:31 > 7:49:33the different chemicals in something,
7:49:33 > 7:49:35like the ink in these pens.
7:49:35 > 7:49:37Andy, what is this?
7:49:37 > 7:49:39This tube is our piece of paper
7:49:39 > 7:49:43and we are pumping this liquid through the tube
7:49:43 > 7:49:45and that's carrying our chilli sample
7:49:45 > 7:49:48and separating the different chemicals.
7:49:48 > 7:49:51The same way as the colour was running up the paper,
7:49:51 > 7:49:55this time, the chilli is running up the tubes, is that right?
7:49:55 > 7:49:57And that's how we can separate all the different parts
7:49:57 > 7:49:59of the chilli out and find its spice factor.
7:49:59 > 7:50:02- Shall we get a real chilli, then? - Let's go for it.- Let's do it.
7:50:02 > 7:50:07'So now we just need to prepare the chillies. Simple, right?'
7:50:08 > 7:50:11'Yeah, it really gets up your nose.'
7:50:11 > 7:50:13Carry on!
7:50:13 > 7:50:14COUGHING
7:50:14 > 7:50:17'And your throat...and your eyes.'
7:50:17 > 7:50:19Goggles are steaming up.
7:50:19 > 7:50:22'Basically, it's just really hot.' Straight up the nose.
7:50:22 > 7:50:25'Well, I've helped Andrew with the strength test,
7:50:25 > 7:50:28'but Barney and Radzi are going to have to wait for those results.'
7:50:28 > 7:50:31Thanks, it's been a really cool day. I say "cool"...
7:50:31 > 7:50:33Chilli!
7:50:33 > 7:50:36No? OK.
7:50:37 > 7:50:39I can still feel my mouth burning.
7:50:39 > 7:50:41What we are about to do is a little bit dangerous.
7:50:41 > 7:50:43It's called the Blue Peter Chilli Challenge,
7:50:43 > 7:50:45so please do not try this at home.
7:50:45 > 7:50:51- Here to help us today is daredevil scientist Greg Foot. Hello, Greg! - CHEERING
7:50:51 > 7:50:54Yay! Thank you so much for being here today.
7:50:54 > 7:50:57- You're welcome. I'm looking forward to this.- I'm excited.
7:50:57 > 7:50:58I'm nervous for you two.
7:50:58 > 7:51:01You have toured all over the UK with live science shows
7:51:01 > 7:51:03and you love anything that mixes science and adrenaline.
7:51:03 > 7:51:05Absolutely.
7:51:05 > 7:51:07Which is why it's perfect you are here today.
7:51:07 > 7:51:10Tell us a little bit about the challenge they are about to do.
7:51:10 > 7:51:13In your video, when he went to the chilli farm
7:51:13 > 7:51:17you found the chemical inside the chilli that makes a chilli hot,
7:51:17 > 7:51:19makes it feel like it's burning, is capsaicin.
7:51:19 > 7:51:23The more capsaicin you have in a chilli, the hotter it is.
7:51:23 > 7:51:27I've got three different chillies. They go from mild to wild.
7:51:27 > 7:51:29Mild to wild, I like it.
7:51:29 > 7:51:33- Are you guys ready for this? - Nope.- Er... Ready as we'll ever be.
7:51:33 > 7:51:36I'm nervous. Shall we start with chilli one? Don't try at home.
7:51:36 > 7:51:39We've got gloves on. That's how hot these chillies are.
7:51:39 > 7:51:43- You've got to have gloves on to taste them.- Absolutely.
7:51:43 > 7:51:45The first one is a jalapeno.
7:51:45 > 7:51:47Jalapeno is what you get on your pizza
7:51:47 > 7:51:48if you have a hot and spicy pizza,
7:51:48 > 7:51:52but they are normally only around 2,500 to 5,000 Scovilles,
7:51:52 > 7:51:54which you talked about in your film. This one, however,
7:51:54 > 7:52:00is a nice, whopping, slightly punchy 30,000 Scovilles.
7:52:00 > 7:52:02- We're starting low. - That is quite spicy, isn't it?
7:52:02 > 7:52:05We laugh in the face of 30,000 Scovilles!
7:52:05 > 7:52:07No time like the present. Cheers.
7:52:08 > 7:52:13- Oh, no.- That's a good bite, Radzi. - I went in far too strong.- You did.
7:52:13 > 7:52:15- How does it feel? - It's a long race.
7:52:15 > 7:52:17The tongue has got very hot, very quickly.
7:52:17 > 7:52:19Let's have a look at the tongue,
7:52:19 > 7:52:21because this is where the action is happening.
7:52:21 > 7:52:26Here is your tongue, it's quite rough. It's lumps and bumps.
7:52:26 > 7:52:29It's got big bumps at the back and little bumps at the front.
7:52:29 > 7:52:33Each of those bumps is called papilla. They're called papillae.
7:52:33 > 7:52:36If you zoom in, this is one from the side.
7:52:36 > 7:52:41You get gaps down the side, these pits. These are your taste buds.
7:52:41 > 7:52:44Each of these green lines, they are neurons going to the brain.
7:52:44 > 7:52:47They send signals about what you are eating to the brain.
7:52:47 > 7:52:50There are receptors inside working out whether it is salt,
7:52:50 > 7:52:53sweet, hot or cold.
7:52:53 > 7:52:55The thing about the capsaicin chemical,
7:52:55 > 7:52:58as these guys are now feeling, is it does something to the receptors,
7:52:58 > 7:53:01so even if you are eating something cold, it feels hot.
7:53:01 > 7:53:04Greg, what you are trying to say is the spice they're feeling
7:53:04 > 7:53:07- is just in the head. - It's all in your head, boys. - It's in my mouth!
7:53:07 > 7:53:10Speaking of which, let's get on to chilli...
7:53:10 > 7:53:13I have given this the big one, all day, and I'm regretting that.
7:53:13 > 7:53:16- Radzi, you're sweating.- I bet you are. This is the second one.
7:53:16 > 7:53:19This is Scotch Bonnet. We should say, don't try this at home.
7:53:19 > 7:53:22This is 200,000 Scovilles.
7:53:22 > 7:53:25We've already stepped up the spice a lot here. Let's go.
7:53:26 > 7:53:29Oh! Oh, no.
7:53:31 > 7:53:35Another massive bite from Radzi. That was impressive.
7:53:35 > 7:53:36How are you doing?
7:53:36 > 7:53:38- Oh.- Oh, Radzi, are you crying?
7:53:38 > 7:53:40That has got some venom to it, that.
7:53:40 > 7:53:44I think we're getting a sweaty nose on, as well, from you guys. Yes.
7:53:44 > 7:53:47This is a natural reaction from the body.
7:53:47 > 7:53:49Your brain thinks you're actually burning.
7:53:49 > 7:53:53- It doesn't think, it knows! - Remember, it's all in the head.
7:53:53 > 7:53:55It thinks you are physically burning.
7:53:55 > 7:53:58It kick-starts all your bodily responses,
7:53:58 > 7:54:00your cooling mechanisms, and that is what sweating is.
7:54:00 > 7:54:03Also, you've gone a little bit red.
7:54:03 > 7:54:08- I'm genuinely sweating.- That is your pain response kicking in.
7:54:08 > 7:54:10Your body is flooded with endorphins and adrenaline
7:54:10 > 7:54:14- and that's why you're flushing red. - Can I say that was...
7:54:14 > 7:54:17- LAUGHTER - Barney's gone.- Is he?!
7:54:17 > 7:54:20- Oh, he's back.- Barney's back.
7:54:20 > 7:54:22I think... Who's feeling brave?
7:54:22 > 7:54:25- Aargh!- I need a drink.
7:54:25 > 7:54:28- OK.- I'm going to do it.
7:54:28 > 7:54:32- OK, let's do this.- This top one is a real top one. OK, are you ready?
7:54:32 > 7:54:34Barney is trying to leave the studio.
7:54:34 > 7:54:38This is the one that you tested and the results are in.
7:54:38 > 7:54:41910,000 Scovilles.
7:54:41 > 7:54:45- It just gets worse, it doesn't get any better.- This is a lot worse.
7:54:45 > 7:54:47This really is going to be spicy.
7:54:47 > 7:54:49- I don't mean this gets worse, that got worse!- Ready?
7:54:49 > 7:54:52- Barns, are you in?- Come on, Barney, we're in this together, mate.
7:54:52 > 7:54:55A little nibble. Don't take much. Just take a little nibble.
7:54:55 > 7:54:57Oh, just a nibble. Don't do too much.
7:54:59 > 7:55:00OK, this is close to 1,000,000.
7:55:00 > 7:55:03I could give you water, but water would not help at all.
7:55:03 > 7:55:06What you guys need is milk. There you go.
7:55:06 > 7:55:09Capsaicin, it's a fatty molecule.
7:55:09 > 7:55:13Think about when you are cleaning your pots and pans at home,
7:55:13 > 7:55:16if it's got fat on there, water does nothing.
7:55:16 > 7:55:19You need something to wash it away. That's what the milk does.
7:55:19 > 7:55:21- Protein in the milk helps wash it away.- Is it helping at all?
7:55:21 > 7:55:26Barney has left the studio. Radzi looks like he's about to cry.
7:55:26 > 7:55:28It's like having an armband in the middle of the Pacific Ocean.
7:55:28 > 7:55:30I can smell it. Oh!
7:55:30 > 7:55:33There you go, it is all in the head and it's down to that capsaicin.
7:55:33 > 7:55:37- Don't try it at home. - We should say a well done to the boys for even giving that a go.
7:55:37 > 7:55:40Greg, thank you so much for being here.
7:55:40 > 7:55:43This is the quietest Barney and Radzi have been all day.
7:55:43 > 7:55:45You can come again!
7:55:45 > 7:55:47Now, at the beginning of the show,
7:55:47 > 7:55:52we asked you to let us know what spy device you would design and why.
7:55:52 > 7:55:54Come with me, guys, come on, you can bring the milk.
7:55:54 > 7:55:57Loads of you have been sending in comments.
7:55:57 > 7:55:59We are going to read a few out.
7:55:59 > 7:56:03I will start, considering Barney and Radzi are struggling to speak.
7:56:03 > 7:56:05Don't cry, guys, you can do it.
7:56:05 > 7:56:07The first is from Red Musical Sea Horse,
7:56:07 > 7:56:10who says, "I would make a super, awesome potato,
7:56:10 > 7:56:12"so that when your enemies are trying to find you,
7:56:12 > 7:56:15"the potato could suck you in so you're hidden."
7:56:15 > 7:56:16A magic potato. I like that a lot.
7:56:16 > 7:56:19- Are you able to read, Radzi? - I'm going to read.
7:56:19 > 7:56:22Magenta Gentle B... Puppy says... Can't read!
7:56:22 > 7:56:25"My gadget would be a newspaper which, when you pointed it
7:56:25 > 7:56:27"at someone, could read his or her mind,
7:56:27 > 7:56:30"because people would think I'm a normal person reading a newspaper."
7:56:30 > 7:56:32Very nice.
7:56:32 > 7:56:36- Are you going to? No, Barney is not even going to attempt it. - LAUGHTER
7:56:36 > 7:56:39Topaz Smiley says, "I would make earmuffs that had
7:56:39 > 7:56:43"a wireless radio inside so I could speak to my spy agents."
7:56:43 > 7:56:46Very nice. Loads of good ideas. Thank you so much.
7:56:46 > 7:56:51Before we finish, we have time to tell you what's on next week's show.
7:56:51 > 7:56:54We are going to be joined by CBBC stars Sam and Mark
7:56:54 > 7:56:57as they tell us all about their next series of Friday Wind-ups.
7:56:57 > 7:56:59It's going to be good.
7:57:01 > 7:57:03BARNEY: Um, also, the big plane might make it.
7:57:03 > 7:57:05I might not make it,
7:57:05 > 7:57:08but will the big wing make it onto the big plane?
7:57:10 > 7:57:13- Um... Right.- I would say calcium is very good for the bones.
7:57:13 > 7:57:15Something that is good for the soul...
7:57:15 > 7:57:17It's time to find out about our next performer, Elyar Fox.
7:57:17 > 7:57:19Let's find out a little bit about him.
7:57:21 > 7:57:23# Ah, check it out. #
7:57:23 > 7:57:24Dubbed the British Justin Bieber,
7:57:24 > 7:57:27Elyar Fox became an internet phenomenon from his bedroom.
7:57:27 > 7:57:30He clocked up over 14 million hits online
7:57:30 > 7:57:34before being snapped up by a record label to record his own music.
7:57:34 > 7:57:37He's just finished a successful tour with boy-band sensation Union J
7:57:37 > 7:57:39and has been working on his debut album
7:57:39 > 7:57:42with some of pop music's biggest songwriters and producers.
7:57:42 > 7:57:44This week, Elyar releases his debut single.
7:57:46 > 7:57:48Earlier on in the Blue Peter studio,
7:57:48 > 7:57:50when I was having a much happier time,
7:57:50 > 7:57:52I managed to get together with Elyar
7:57:52 > 7:57:55and we recorded our own version of One Direction's...
7:57:55 > 7:57:58Yeah, they recorded One Direction's Story Of My Life. It's all online.
7:58:01 > 7:58:04Make sure you check it out. But now it's time to hear from Elyar Fox.
7:58:04 > 7:58:08It's a live acoustic version of his debut single. Let's hear it.
7:58:11 > 7:58:12# Hey!
