0:00:04 > 0:00:07Coming up, there's a feathery feeling on Blue Peter this week.
0:00:07 > 0:00:09Keep watching to see some very cute owls.
0:00:09 > 0:00:12Barney's feeling explosive as he learns how to blow up buildings,
0:00:12 > 0:00:13safely of course.
0:00:13 > 0:00:15And singing sensation Tich is going to be here
0:00:15 > 0:00:18performing for you. That's all on today's Blue Peter.
0:00:34 > 0:00:35CHEERING
0:00:35 > 0:00:37Hello!
0:00:37 > 0:00:39Yes! Well, the clocks have gone forward,
0:00:39 > 0:00:43- which means you have even longer to play out after your tea.- Yes!
0:00:43 > 0:00:46And someone who's definitely got a spring in her step is Emily
0:00:46 > 0:00:49who's made this fabulous 3D picture of flowers.
0:00:49 > 0:00:51- That is SO good. - In fact, we like it so much,
0:00:51 > 0:00:53it's going to take pride of place right there.
0:00:53 > 0:00:55I love it, Emily, thank you very much for sending us that.
0:00:55 > 0:00:58- Now, Barney's not here today.- Aww!
0:00:58 > 0:01:01- But don't worry, he's back next week!- Yeah!
0:01:01 > 0:01:02- I miss Barney, actually.- I... Do!
0:01:02 > 0:01:04No, I've got to admit, I do a little bit
0:01:04 > 0:01:07but don't worry, Radzi, we're about to see his little face.
0:01:07 > 0:01:08And that's because last week,
0:01:08 > 0:01:11Barney went to a block of flats just near the studios here
0:01:11 > 0:01:13to find the answer to a very difficult question.
0:01:13 > 0:01:18And that is, how do you blow up a 13-storey, 9,000 tonne building
0:01:18 > 0:01:22without damaging the houses around it, that are just metres away?
0:01:22 > 0:01:24The answer is, not very easily!
0:01:30 > 0:01:33The Falcon Court building in Manchester.
0:01:33 > 0:01:369,000 tonnes of concrete. And it's 35 metres high.
0:01:36 > 0:01:39It really is a huge part of the skyline here.
0:01:39 > 0:01:42When the tower block was built 40 years ago,
0:01:42 > 0:01:45it was a modern and exciting place to live.
0:01:45 > 0:01:46But in 2014, it's past its best,
0:01:46 > 0:01:49so the local council has decided to demolish it
0:01:49 > 0:01:51to make way for new, more modern homes.
0:01:51 > 0:01:53Yep, they're going to blow it up.
0:01:53 > 0:01:55But how do you demolish something so large
0:01:55 > 0:01:58while protecting the houses that are just metres from the blast?
0:01:59 > 0:02:02If you've every played with one of these,
0:02:02 > 0:02:06you'll know how just easy it is to make something fall over.
0:02:06 > 0:02:08Oops! Yeah.
0:02:08 > 0:02:09But if it goes THAT wrong,
0:02:09 > 0:02:14it could have disastrous consequences for the houses around it.
0:02:14 > 0:02:16Ah! That's better.
0:02:16 > 0:02:21So a successful demolition should fall neatly in on itself,
0:02:21 > 0:02:24like these Dundee tower blocks did back in 2011.
0:02:24 > 0:02:28But not all demolitions are executed as precisely as that.
0:02:28 > 0:02:31In 2009, the demolition of this Turkish factory
0:02:31 > 0:02:33went dramatically wrong.
0:02:34 > 0:02:37Martin Smith is the man in charge of the safety
0:02:37 > 0:02:38of the Falcon Court demolition.
0:02:38 > 0:02:40Do you like what I've done with the place?
0:02:40 > 0:02:42I do, yeah, it's really good.
0:02:42 > 0:02:45it looks like we're in what used to be someone's home.
0:02:45 > 0:02:47It would. This would have been one person's flat
0:02:47 > 0:02:50with a doorway just behind us here.
0:02:50 > 0:02:52You can see, we've started our pre-weakening process
0:02:52 > 0:02:55to remove some of the structural elements of the building.
0:02:55 > 0:02:58The explosives do some of the work, but by pre-weakening it,
0:02:58 > 0:02:59that does the rest.
0:03:01 > 0:03:03The demolition team have drilled holes in the walls
0:03:03 > 0:03:06that are supporting the weight of the building, to make it less stable.
0:03:08 > 0:03:11The team will then place explosives on three floors,
0:03:11 > 0:03:14blasting away walls that help keep the building standing.
0:03:14 > 0:03:16The idea being that, once they go,
0:03:16 > 0:03:19the already pre-weakened building should fall in on itself,
0:03:19 > 0:03:22leaving a neat pile of rubble.
0:03:22 > 0:03:24It's three weeks before demolition day
0:03:24 > 0:03:27and the team are about to carry out a test blast on one piece of wall.
0:03:27 > 0:03:29I would love to see some explosives going in.
0:03:29 > 0:03:31Could you do that for us?
0:03:31 > 0:03:34John is an expert in blasting big buildings.
0:03:34 > 0:03:38This is the explosive. It is filled with PETN, the white powder.
0:03:38 > 0:03:40What does PETN stand for?
0:03:40 > 0:03:42Pentaerythritol tetranitrate.
0:03:42 > 0:03:44Did you write that down?
0:03:44 > 0:03:46We are going to put one length of purple.
0:03:46 > 0:03:51We will make the weak spots and this is the just tool to take it out.
0:03:51 > 0:03:52All yours.
0:03:52 > 0:03:54By carrying out a test blast, John will be able to see
0:03:54 > 0:03:58if his plans for the overall demolition are accurate.
0:03:58 > 0:04:01They look a bit like the pick and mix sweets at the cinema.
0:04:01 > 0:04:03But I wouldn't eat one of those, though.
0:04:03 > 0:04:05On the demolition day itself,
0:04:05 > 0:04:08using too little explosive might not topple the tower block.
0:04:08 > 0:04:11Too much, and it might explode everywhere,
0:04:11 > 0:04:14causing damage to the surrounding buildings.
0:04:14 > 0:04:16What do you want to see when we come back into the building?
0:04:16 > 0:04:19We'll give it ten minutes after the explosive's gone off
0:04:19 > 0:04:21to let the proverbial dust settle.
0:04:21 > 0:04:23But we expect to see a big bag of the concrete
0:04:23 > 0:04:25and when we cut it open,
0:04:25 > 0:04:27there'll be a big section of the wall missing
0:04:27 > 0:04:30and the concrete that was there is sat in the bottom of the bag.
0:04:30 > 0:04:35It's time for us to leave and see if John has got his sums right.
0:04:35 > 0:04:38If you see anything in that period when I'm quiet
0:04:38 > 0:04:41that may need to stop, shout, "Stop, Stop!" OK?
0:04:41 > 0:04:43Are we all ready? Good to go?
0:04:43 > 0:04:44Fire now.
0:04:44 > 0:04:47EXPLOSION
0:04:47 > 0:04:49I wasn't expecting that!
0:04:49 > 0:04:50That was louder than I expected.
0:04:50 > 0:04:53You didn't give me a warning about that one, did you?
0:04:53 > 0:04:56After a few minutes, it's safe to go back in and have a look.
0:04:56 > 0:05:00That wall has effectively gone now, hasn't it, what was there before?
0:05:00 > 0:05:03So how do you know now how successful the blast was?
0:05:03 > 0:05:05We'll cut open the geotextile
0:05:05 > 0:05:10and clip open the chain-link fence beneath and when the debris spills
0:05:10 > 0:05:15out, it will tell us the explosives have done the job as we wanted.
0:05:15 > 0:05:17Would you call that a successful test?
0:05:17 > 0:05:19I would call that very successful.
0:05:21 > 0:05:23Three weeks on, it's demolition day.
0:05:23 > 0:05:26The finishing touches are being made to the building
0:05:26 > 0:05:28while teams from the local council
0:05:28 > 0:05:31are evacuating the homes of local residents.
0:05:31 > 0:05:34It's not because the building's going to fall on top of theirs,
0:05:34 > 0:05:35it's just a precaution,
0:05:35 > 0:05:37to make sure they're safe and away from the blast
0:05:37 > 0:05:40but if that building falls down the way it should do, which it will,
0:05:40 > 0:05:41it's just going to drop.
0:05:41 > 0:05:45At a safe distance away, there's an excited crowd watching
0:05:45 > 0:05:47and I'm being allowed inside the exclusion zone.
0:05:47 > 0:05:49I'm actually getting really excited.
0:05:49 > 0:05:51Everything's moving pretty quickly now.
0:05:51 > 0:05:54I'm with Martin and John, ready for when they push the button
0:05:54 > 0:05:56to bring the block down.
0:05:56 > 0:05:58Century 9, receiving, over?
0:05:58 > 0:06:00'Loud and clear.'
0:06:00 > 0:06:03And it's not just the homes we have to worry about.
0:06:03 > 0:06:05We've placed two cameras at the base of the building.
0:06:05 > 0:06:09Let's hope John's got this one right, or they might get crushed.
0:06:10 > 0:06:13Ten, nine, eight,
0:06:13 > 0:06:16seven, six, five...
0:06:16 > 0:06:21CROWD JOIN IN: Four, three, two, one!
0:06:21 > 0:06:23Fire now!
0:06:23 > 0:06:26BOOM!
0:06:27 > 0:06:29WHOOPING
0:06:37 > 0:06:39Have you ever seen anything like that?!
0:06:39 > 0:06:44Look at the dust cloud coming over here. Wow! That's incredible!
0:06:44 > 0:06:45Four years to build it.
0:06:45 > 0:06:47Four seconds to demolish it.
0:06:47 > 0:06:51You want to see an action replay, don't you? Check this out.
0:06:51 > 0:06:54MUSIC: "Push The Button" by The Chemical Brothers
0:06:54 > 0:06:56# Push the button! #
0:07:09 > 0:07:11That was brilliant!
0:07:11 > 0:07:12Here comes the dust.
0:07:14 > 0:07:17HE PURSES LIPS AND BLOWS
0:07:17 > 0:07:18Oh, I'm so jealous! That looked like
0:07:18 > 0:07:21a really exciting day for Barney, the crew and the local community,
0:07:21 > 0:07:24and if you saw one of cameras there on the day
0:07:24 > 0:07:26that got covered in rubble, this is it. It survived.
0:07:26 > 0:07:29How good is that? Now follow me this way, it's the Big Badge Wall.
0:07:29 > 0:07:32As usual, it's covered in your brilliant post.
0:07:32 > 0:07:34Thanks very much for sending it in.
0:07:34 > 0:07:37I had to mention this from Clifton in Chesterfield.
0:07:37 > 0:07:41It's a book and it's got Blue Peter, it's got absolutely everything in it
0:07:41 > 0:07:44and even at the very back, there is a CBBC Quiz.
0:07:44 > 0:07:48- We've got to do that later. - We will do that later on!
0:07:48 > 0:07:53Nia is from Cardiff and we are all aboard the Blue Peter ship. Aye-aye!
0:07:53 > 0:07:56We love it. This is from Charlotte, she's ten and she's done us three
0:07:56 > 0:07:59but Barney's got a little camera, and if you look carefully
0:07:59 > 0:08:01on the top left, there's an owl.
0:08:01 > 0:08:04There's going to be more from those later.
0:08:04 > 0:08:05I like it. I love this from Ella.
0:08:05 > 0:08:09She has made all of the replicas of the Blue Peter badges.
0:08:09 > 0:08:11But we can't send Ella a Blue Peter badge.
0:08:11 > 0:08:13Why? because she didn't include her address!
0:08:13 > 0:08:16If you do send us post, make sure you include your address.
0:08:16 > 0:08:18Someone who did include their address was Daniel.
0:08:18 > 0:08:19This is brilliant.
0:08:19 > 0:08:22He's done a Blue Peter Bot, Barney's controlling the robot
0:08:22 > 0:08:24there's a poem with it, it's brilliant,
0:08:24 > 0:08:26and he got a silver badge for it
0:08:26 > 0:08:29because it's your second piece of great work.
0:08:29 > 0:08:33And this is from Nicholas, who's 11. He's done an environmental picture.
0:08:33 > 0:08:36Again, as well as all the other animals,
0:08:36 > 0:08:38there's another little owl. We like that very much.
0:08:38 > 0:08:40It's earned you a green badge. Well done.
0:08:40 > 0:08:43To find out more about all of the Blue Peter badges,
0:08:43 > 0:08:48jump on to our website -

0:08:56 > 0:08:58- # Ah- # Ah- # Ah- # Ah
0:08:58 > 0:08:59# Badges
0:09:01 > 0:09:03# Blue Peter badges
0:09:04 > 0:09:07HE RAPS: # There's loads of different colours to adorn your sternum
0:09:07 > 0:09:10# Can't buy them in the shops, you have to earn 'em
0:09:10 > 0:09:12# What did you do to get your
0:09:12 > 0:09:14# Blue Peter badge?
0:09:15 > 0:09:19So you're saying there is more than blue, then, that me and you've got?
0:09:19 > 0:09:20Yeah, there's...
0:09:20 > 0:09:22.. as well as the blue one.
0:09:22 > 0:09:25Wow. You must have worked really hard, especially for that gold one.
0:09:25 > 0:09:26Yeah!
0:09:26 > 0:09:28Er, no, I just borrowed 'em.
0:09:28 > 0:09:30RAPPING: # Anyway, let me talk you through them all.
0:09:30 > 0:09:33# This is the one that you've probably all seen before, right?
0:09:33 > 0:09:36# But "how do I get one?" is doubtless what you want to know
0:09:36 > 0:09:39# Well, it's as simple as sending something into the show
0:09:39 > 0:09:42# Could be a poem or a story, serious or silly
0:09:42 > 0:09:45# Could be a picture that you've done, specifically for Lindsey
0:09:45 > 0:09:47# Got a great idea? Stick it in an e-mail or letter
0:09:47 > 0:09:51# And in return you could be rewarded with this handsome treasure...
0:09:51 > 0:09:53I've already got one, but I've written this really good rhyme.
0:09:53 > 0:09:56Funny you should say that, because if you send something in
0:09:56 > 0:09:58- a second time, you could get a silver badge.- Wow!
0:09:58 > 0:09:59Yeah, and look at it gleam.
0:09:59 > 0:10:03Except, technically, you can't get any cos you're over the age of 15.
0:10:03 > 0:10:05# Have you seen this orange one? It's even more rare
0:10:05 > 0:10:08# If anybody's the owner of one of these out there
0:10:08 > 0:10:11# It's cos they've won or were runner-up in a BP competition
0:10:11 > 0:10:14# It's a miniature trophy you can wear on your britches!
0:10:14 > 0:10:17# Fancy answering some questions about an episode of Blue Peter?
0:10:17 > 0:10:20# Fill in the feedback form and get a purple badge, feast your peepers
0:10:20 > 0:10:22# Or is green more your colour? If it's the green badge you favour
0:10:22 > 0:10:24# Just submit stuff about
0:10:24 > 0:10:26# The environment, conservation or nature...
0:10:26 > 0:10:28What's this about a sports badge, I think I heard you say?
0:10:28 > 0:10:31It's fairly self-explanatory, Stephen - clue's in the name!
0:10:31 > 0:10:34# This one's only available in summer and to get it, in short
0:10:34 > 0:10:37# You have to have inspired other people to get involved in sport
0:10:37 > 0:10:40# Then there's the gold one. Notice the music's gone all celestial
0:10:40 > 0:10:43# You can only get one of these if you do something REALLY special
0:10:43 > 0:10:46# Demonstrate amazing courage in the face of danger
0:10:46 > 0:10:49# Like saving someone's life or something equally major
0:10:49 > 0:10:52# Some gold badge owners you might have heard of, I reckon,
0:10:52 > 0:10:55# Jessica Ennis has got one and so has David Beckham
0:10:55 > 0:10:58# The most famous person to own a badge, by far, though,
0:10:58 > 0:11:01# Is a little northern chap by the name of Gary Barlow...
0:11:01 > 0:11:02Isn't it the Queen?
0:11:02 > 0:11:06- Hmm?- I'm sure it's Her Majesty, the Queen.
0:11:06 > 0:11:09No, no, you're right, it's Her Majesty, the Queen.
0:11:11 > 0:11:12# Badges!
0:11:13 > 0:11:15# Blue Peter badges!
0:11:16 > 0:11:19# There's loads of different colours to adorn your sternum
0:11:19 > 0:11:22# Can't buy them in the shops, you have to earn 'em
0:11:22 > 0:11:25# They can get you into theme parks, castles and zoos
0:11:25 > 0:11:28# They can liven up your jumper or your bag or your shoes
0:11:28 > 0:11:30# What will you do?
0:11:30 > 0:11:32- # What will you do? - # What will you do?
0:11:32 > 0:11:34# What will you do, to get your...
0:11:34 > 0:11:35# Blue Peter badge? #
0:11:35 > 0:11:37I love Brett Domino.
0:11:37 > 0:11:39You can head to the website and check out online
0:11:39 > 0:11:42if you want to show your friends or just see it again.
0:11:42 > 0:11:45Now. You might have guessed, it is time for our feathery feature.
0:11:45 > 0:11:48This is Mumble. We will meet him properly later.
0:11:48 > 0:11:49Before that, do you know what?
0:11:49 > 0:11:52This is the first time I've ever been this close to an owl.
0:11:52 > 0:11:56But for Jake, who's 11, meeting a bird of prey like this
0:11:56 > 0:11:58is just part of his everyday life. Check this out.
0:11:58 > 0:12:04Hi, I'm Jake and I look after real live birds of prey.
0:12:04 > 0:12:06This is what it's like being me.
0:12:07 > 0:12:10My family run a bird of prey centre.
0:12:10 > 0:12:12I help out after school and at weekends.
0:12:12 > 0:12:14As soon as I get home,
0:12:14 > 0:12:19I get changed, grab a bite to eat and head over to the centre.
0:12:19 > 0:12:24We have over 50 different species of birds here,
0:12:24 > 0:12:26including owls,
0:12:26 > 0:12:28storks and eagles.
0:12:30 > 0:12:32But my three favourite are...
0:12:32 > 0:12:35Peregrine falcons are the fastest bird in the world.
0:12:35 > 0:12:38They can even catch other birds in mid-air.
0:12:38 > 0:12:40Kestrels have amazing eyesight
0:12:40 > 0:12:43which helps them catch small animals like mice and voles.
0:12:45 > 0:12:49Vultures wee on themselves on hot days to help keep them cool
0:12:49 > 0:12:50and to kill off bacteria.
0:12:53 > 0:12:55One of my jobs is weighing the birds.
0:12:55 > 0:12:57If they're too heavy, they can't fly.
0:12:57 > 0:12:58If they're too light,
0:12:58 > 0:13:01they don't have the energy and the strength to fly.
0:13:03 > 0:13:05This one is overweight.
0:13:07 > 0:13:09But this one is just right.
0:13:11 > 0:13:13It might look like a glamorous job,
0:13:13 > 0:13:15but I also have to clean out the feathers and poo.
0:13:17 > 0:13:19I also show people around the centre
0:13:19 > 0:13:22and tell them facts. Say hi, everyone!
0:13:22 > 0:13:23ALL: Hi!
0:13:23 > 0:13:25'There is a lot for me to do.
0:13:25 > 0:13:30'But don't worry, I have my mum, dad and my two sisters -
0:13:30 > 0:13:32'Daisy and Lily.'
0:13:34 > 0:13:38'My dad has been working with birds of prey for 30 years.
0:13:38 > 0:13:41'And as I get older, he is training me too.
0:13:41 > 0:13:44'One day I would like to run a centre just like him.'
0:13:44 > 0:13:47DAD: ..here at the centre, all part of our show.
0:13:47 > 0:13:51At the weekends, we put on shows,
0:13:51 > 0:13:54where we fly the birds for the public.
0:13:54 > 0:13:55Those birds are kites,
0:13:55 > 0:13:58they're the oldest species of bird of prey in the world.
0:13:59 > 0:14:01I do have other interests.
0:14:02 > 0:14:04I'm learning to play the guitar.
0:14:04 > 0:14:07ELECTRIC GUITAR RIFF RECORD SCRATCHES
0:14:07 > 0:14:09Well, I said I was learning.
0:14:10 > 0:14:13At the moment, I am hand-rearing a ten-day-old owl.
0:14:15 > 0:14:18It's living with me while it's cold outside.
0:14:18 > 0:14:22Blue Peter viewers have sent in questions for me.
0:14:22 > 0:14:24Star Stone Peach Octopus says...
0:14:24 > 0:14:27"How do you know when one or more birds are ill?"
0:14:27 > 0:14:31They act differently, and sometimes they won't fly
0:14:31 > 0:14:33and they just won't eat.
0:14:33 > 0:14:35Violet Puffy Spangle says...
0:14:35 > 0:14:40"If you could be any bird, which one would it be and why?"
0:14:40 > 0:14:42Probably a Ruppelle's griffon,
0:14:42 > 0:14:44because they soar higher than planes.
0:14:44 > 0:14:46Siam Fuzzy Puma asks...
0:14:46 > 0:14:49"Who is your favourite celebrity?"
0:14:49 > 0:14:53David Attenborough, because he works with wildlife around the world.
0:14:53 > 0:14:56Star Stone Whirling Hamster asks...
0:14:56 > 0:14:58"Has a bird ever pooped on you?"
0:14:58 > 0:15:03One day I was cleaning an aviary and two baby turkey vultures
0:15:03 > 0:15:07were on a perch and one directed it
0:15:07 > 0:15:10right at me, and it went right down my face.
0:15:10 > 0:15:12Star Stone Creative Cheetah wants to know...
0:15:12 > 0:15:14"What is your favourite bird and why?"
0:15:14 > 0:15:16Funny you should ask that.
0:15:16 > 0:15:18This is one of my favourite kestrels.
0:15:18 > 0:15:21She's called Whisper. I have to wear a special glove
0:15:21 > 0:15:23so her talons don't dig into me.
0:15:23 > 0:15:26And this is a pouch where I keep her dinner.
0:15:26 > 0:15:28You feel like flying today, Whisper?
0:15:34 > 0:15:38I like Whisper because I love the way she acts with me.
0:15:46 > 0:15:48I hope you've enjoyed seeing what it is like
0:15:48 > 0:15:49to work with birds of prey.
0:15:49 > 0:15:52And this is what it's like being me.
0:15:53 > 0:15:56Do you know what? Hearing Jake's story about bird poo,
0:15:56 > 0:15:58I'm hoping our next guests are on their best behaviour.
0:15:58 > 0:16:02Normally we give them a big round of applause, but today just a quiet one,
0:16:02 > 0:16:05for Mumble and Atka with Carole and Vicki. Hello!
0:16:05 > 0:16:09Thank you so much for coming in today. Oh, Mumble's getting excited!
0:16:09 > 0:16:11So, Carol, what type of owl is he?
0:16:11 > 0:16:15He is a European eagle owl, one of the largest of all owls.
0:16:15 > 0:16:18- Although he's actually quite a small male.- Oh, really?
0:16:18 > 0:16:19The females are much bigger.
0:16:19 > 0:16:21I thought he was really heavy, what about Atka?
0:16:21 > 0:16:26Atka's a bit heavier than Mumble, a couple of pound more.
0:16:26 > 0:16:30- And what type of owl is she? - She's a female snowy owl.
0:16:30 > 0:16:33Are we likely to see them in the UK? If I looked out my window...
0:16:33 > 0:16:36You wouldn't see Atka. They live in colder climates.
0:16:36 > 0:16:38ATKA HOOTS
0:16:38 > 0:16:41They live in, like, the Outer Hebrides, Iceland...
0:16:41 > 0:16:42But you could see an eagle owl,
0:16:42 > 0:16:44there are a few pairs in this country.
0:16:44 > 0:16:47How old are Mumble and Atka?
0:16:47 > 0:16:50Mumble is coming up to five, and Atka is three.
0:16:50 > 0:16:55- And how old will they get?- They can live 30 years plus in captivity,
0:16:55 > 0:16:58but in the wild, it can be as little as three years.
0:16:58 > 0:17:02So why are they good predators?
0:17:02 > 0:17:07They've got fabulous eyesight, and their hearing is very good.
0:17:07 > 0:17:11Certainly, with the barn owl, they are totally silent in flight.
0:17:11 > 0:17:14These can be quite big, but they don't make a lot of noise,
0:17:14 > 0:17:16so their prey doesn't hear them coming.
0:17:16 > 0:17:21It seems strange they hunt at dusk or dawn, is it not harder to see?
0:17:21 > 0:17:25Different owls have different colours of eyes,
0:17:25 > 0:17:28and that denotes whether they are nocturnal or diurnal hunters.
0:17:28 > 0:17:32Some hunt when it goes dark, some hunt when it's getting light.
0:17:32 > 0:17:36If you look closely at Atka, has she got two different eyelids?
0:17:36 > 0:17:40Yeah, they have what's called a nictitating membrane
0:17:40 > 0:17:44which helps them to clear their eye and when they're flying
0:17:44 > 0:17:46it's like a visor, really.
0:17:46 > 0:17:48It just protects their eye.
0:17:48 > 0:17:50They've got one that protects it
0:17:50 > 0:17:52and one that's a bit like a windscreen wiper.
0:17:52 > 0:17:54Yeah, they don't blink as much with the full eyelid,
0:17:54 > 0:17:56but you will see that one quite often.
0:17:56 > 0:17:59I think we've actually got that in slow motion.
0:18:01 > 0:18:03That is amazing, two eyelids.
0:18:03 > 0:18:06You've brought some eggshells in with you today,
0:18:06 > 0:18:09what is this little one?
0:18:09 > 0:18:10An English barn owl egg.
0:18:10 > 0:18:13- And this big one?- And that one is a European eagle owl.
0:18:13 > 0:18:17- Wow, so this one grows into Mumble? - Yes.
0:18:17 > 0:18:19What do they eat when they're just little babies?
0:18:19 > 0:18:25Their parents will bring them mice, voles, small animals like that.
0:18:25 > 0:18:28The parents will tear it up and feed the chicks,
0:18:28 > 0:18:32until they're old enough to eat the full animal themselves.
0:18:32 > 0:18:34OK, let's do some owl myth-busting.
0:18:34 > 0:18:39- I have heard that they can turn their heads 360 degrees, is it true?- No.
0:18:39 > 0:18:43- Aww! So how far? - Just past 180 degrees,
0:18:43 > 0:18:45but they can turn it different ways as well,
0:18:45 > 0:18:47so they can look upside down.
0:18:47 > 0:18:50They've got a lot of extra vertebrae in their neck
0:18:50 > 0:18:53because they need to be able to see a lot.
0:18:53 > 0:18:56Their eyes are fixed in their skull, so they can't look
0:18:56 > 0:19:00side-to-side like we can, which is why they need to turn their head.
0:19:00 > 0:19:05And owl myth number two is that they're wise.
0:19:05 > 0:19:09- They have to be really clever, yes. - Oh, yes.
0:19:09 > 0:19:15Just to be able to survive, they have to be alert all the time.
0:19:15 > 0:19:18Survival isn't easy for them, so they need to be clever.
0:19:18 > 0:19:20- So they are wise, Mumble's a wise old owl?- Yes.
0:19:20 > 0:19:23- MUMBLE HOOTS - Not particularly old, are you?
0:19:23 > 0:19:25He can hear us speaking about him!
0:19:25 > 0:19:27Thank you very much for bringing them in today.
0:19:27 > 0:19:30I just knew meeting these owls was going to be a hoot.
0:19:30 > 0:19:32CAROLE AND VICKI LAUGH Get it? Over to you.
0:19:34 > 0:19:36That there was a Barney Harwood joke.
0:19:36 > 0:19:37Now, it is time to welcome to Blue Peter -
0:19:37 > 0:19:40put your hands together, make some noise, for Tich!
0:19:40 > 0:19:42APPLAUSE AND CHEERING
0:19:42 > 0:19:45- Welcome to Blue Peter. How are you? - I am very well, how are you?
0:19:45 > 0:19:47I am very, very good.
0:19:47 > 0:19:50It is probably fair to say your pop career has just skyrocketed,
0:19:50 > 0:19:52with four million hits online,
0:19:52 > 0:19:54you've been touring with the likes of Olly Murs, Little Mix,
0:19:54 > 0:19:57One Direction, how on earth are you feeling at this point?
0:19:57 > 0:19:59I am so lucky, I am so happy.
0:19:59 > 0:20:02It is an absolute honour to be able to share the stage
0:20:02 > 0:20:04with such amazing artists.
0:20:04 > 0:20:07- And just live the music dream. - Exactly.
0:20:07 > 0:20:09A little bird tells me that you're a bit of a fashionista?
0:20:09 > 0:20:12I love fashion, I always have done.
0:20:12 > 0:20:16I love going through the magazines, picking out different styles,
0:20:16 > 0:20:19I love experimenting with colours and different shapes.
0:20:19 > 0:20:23- Yes, it is a big hobby of mine. - Well, you will love this, then.
0:20:23 > 0:20:27We will be showing you how to make one of these T-shirts.
0:20:27 > 0:20:30All of the instructions and details are on our website...
0:20:34 > 0:20:37Now, you may have seen something similar to this with tie-dying,
0:20:37 > 0:20:42but this is much less messy, and in my opinion, much cooler.
0:20:42 > 0:20:46You need a plain coloured T-shirt, plastic cups,
0:20:46 > 0:20:49coloured permanent markers, a paintbrush,
0:20:49 > 0:20:51elastic bands, and the important part -
0:20:51 > 0:20:56make-up remover, but this is the liquid, and not the lotion.
0:20:56 > 0:21:01First, Tich, we have to place a plastic cup in between the T-shirt.
0:21:01 > 0:21:04Then you take an elastic band and wrap it
0:21:04 > 0:21:06- round the rim of the cup.- What?
0:21:06 > 0:21:08That becomes our canvas.
0:21:08 > 0:21:13Simply repeat the process and choose a pattern of your desire.
0:21:13 > 0:21:15- I have gone...- Very nice.
0:21:15 > 0:21:20..for the three across the top, much like my favourite crossword.
0:21:20 > 0:21:22- What have you gone for, Tich? - A diagonal,
0:21:22 > 0:21:26I wanted to spread the design throughout the whole T-shirt.
0:21:26 > 0:21:29I like it, but while we do that, there are loads of questions
0:21:29 > 0:21:31the viewers sent in, I think Lindsey's going to ask them.
0:21:31 > 0:21:35- We've got loads for you, Tich. - Oh!- So we'll just dive straight in.
0:21:35 > 0:21:37The first one's from Green Sweet Giraffe, he says...
0:21:37 > 0:21:39"What gives you inspiration for your songs?"
0:21:39 > 0:21:43Inspiration for me comes from real life things.
0:21:43 > 0:21:47- I guess my songs are like a diary. - I like it.
0:21:47 > 0:21:48Ruby Sprinkles Shark says...
0:21:48 > 0:21:51"What's your favourite song to dance to?"
0:21:51 > 0:21:55I think anything from when I was growing up, really.
0:21:55 > 0:22:00- I love Britney Spears.- Yes. - Backstreet Boys.- Nineties.
0:22:00 > 0:22:03- Good pop music. - And Smiling Chimp says...
0:22:03 > 0:22:06"What would you do if you weren't a singer?"
0:22:06 > 0:22:10I think I would aspire to be a chef. Or a baker...
0:22:10 > 0:22:13or a candlestick maker!
0:22:13 > 0:22:17I like what you did there. Poetry as well as a singer!
0:22:17 > 0:22:20Now, it gets a bit messy at this point,
0:22:20 > 0:22:22worth putting a newspaper underneath.
0:22:22 > 0:22:26We need to drip this onto the colours,
0:22:26 > 0:22:28we are not pouring it.
0:22:28 > 0:22:32- And then we will work the colour in with the paintbrush.- Oh, wow.
0:22:32 > 0:22:38- You can possibly see the colours begin to run.- Oh, dear.
0:22:38 > 0:22:42- Tiny drip.- Tich, yours looks good.
0:22:42 > 0:22:44I like how you've mixed the colours,
0:22:44 > 0:22:45that looks really cool. TICH LAUGHS
0:22:45 > 0:22:48Now, there is also something I should have possibly said -
0:22:48 > 0:22:52not to put too much on, otherwise it might look like that!
0:22:52 > 0:22:57- It looks good!- Can I just say, it was meant to be a happy star.
0:22:57 > 0:23:02- Well, it's a something star. - Now it's a star in the night sky.
0:23:02 > 0:23:07Once you have done this on all three of the cups, wait for it to dry
0:23:07 > 0:23:10for two hours, pop off the elastic bands, take the cups out,
0:23:10 > 0:23:13and then you will end up with T-shirts which look like those.
0:23:13 > 0:23:15How good do they look?!
0:23:15 > 0:23:18You might also get permanent marker on your fingers,
0:23:18 > 0:23:19so you can use warm, soapy water.
0:23:19 > 0:23:22The T-shirts, if you want to wash those,
0:23:22 > 0:23:24hand wash them in cool water, do not put them
0:23:24 > 0:23:28in the washing machine, the colour will go everywhere.
0:23:28 > 0:23:31If you have done one, take a photo and send them to us.
0:23:31 > 0:23:33We love when you get involved with our makes. It's...
0:23:35 > 0:23:38We'll try and put as many photos as possible online.
0:23:40 > 0:23:43It's time to take a look at what you've done so far. Wow!
0:23:43 > 0:23:46- That is exceptional work. - Lovely, really nice.
0:23:46 > 0:23:49Something which you are exceptional at is singing, and we're
0:23:49 > 0:23:51going to be seeing you in just a few moments.
0:23:51 > 0:23:53- Thank you so much for coming to visit us.- Thank you.
0:23:53 > 0:23:55Now, whilst Tich goes and gets herself ready,
0:23:55 > 0:23:57here's what is coming up next week.
0:23:57 > 0:24:00The three of us will be taking on a dance challenge
0:24:00 > 0:24:04with the cast of CBBC show The Next Step - you are going to love it.
0:24:04 > 0:24:09And we will be showing you how to make these Easter egg nests.
0:24:09 > 0:24:10And I will be facing
0:24:10 > 0:24:13one of my biggest fears, it is fish.
0:24:13 > 0:24:16And I absolutely hated them, they were terrifying!
0:24:16 > 0:24:18Find out how I got on next week, but now,
0:24:18 > 0:24:20performing her brand-new single - which I love -
0:24:20 > 0:24:24- it is Tich, with Breathe In Breathe Out.- Woo!
0:24:32 > 0:24:34# Woke up too late for the train
0:24:34 > 0:24:35# Routine always the same
0:24:35 > 0:24:40# Another day in a life like any other
0:24:40 > 0:24:42# I ran straight through the rain
0:24:42 > 0:24:44# Saw your face when I felt the flame
0:24:44 > 0:24:47# Both knew it wasn't a day like any other
0:24:49 > 0:24:51# We're in a moment now
0:24:54 > 0:24:56# I can't believe it how
0:24:56 > 0:25:00# One touch, and suddenly I need you
0:25:00 > 0:25:03# Tough luck, won't you tell me that it ain't true?
0:25:03 > 0:25:05# You're gonna push me
0:25:05 > 0:25:08# Promise you'll break my fall
0:25:10 > 0:25:14# Oh, hold me close as I breathe in, breathe out
0:25:14 > 0:25:15# Breathe in, breathe out
0:25:15 > 0:25:19# I'm on the edge, just take me now
0:25:19 > 0:25:21# And if you're gonna push me
0:25:21 > 0:25:24# Then promise you'll break my fall
0:25:27 > 0:25:30# Face down, I hit the floor
0:25:30 > 0:25:32# Nothing to hide any more
0:25:32 > 0:25:34# I've tried, but what is the use?
0:25:34 > 0:25:37# I was always looking from a bird's eye view
0:25:37 > 0:25:40# Dreaming of when I'd find you
0:25:40 > 0:25:43# But I know I will never be the same
0:25:45 > 0:25:47# We're in a moment now
0:25:50 > 0:25:52# I can't believe it how
0:25:52 > 0:25:55# One touch, and suddenly I need you
0:25:55 > 0:25:59# Tough luck, won't you tell me that it ain't true?
0:25:59 > 0:26:04# You're gonna push me, promise you'll break my fall
0:26:04 > 0:26:09# Oh, hold me close as I breathe in, breathe out
0:26:09 > 0:26:11# Breathe in, breathe out
0:26:11 > 0:26:14# I'm on the edge, just take me now
0:26:14 > 0:26:20# And if you're gonna push me, then promise you'll break my fall
0:26:24 > 0:26:26# Breathe in, breathe out
0:26:26 > 0:26:28# Like a love I can't stop
0:26:28 > 0:26:32# Need you here, need you now, cos you've got my heart
0:26:32 > 0:26:34# Breathe in, breathe out
0:26:34 > 0:26:37# Baby, forever free falling
0:26:40 > 0:26:44# One touch, and suddenly I need you
0:26:44 > 0:26:48# Tough luck, won't you tell me that it ain't true?
0:26:48 > 0:26:53# You're gonna push me, promise you'll break my fall
0:26:54 > 0:26:56# You'll break my fall!
0:27:01 > 0:27:05# Whoa-oh-ohhh
0:27:10 > 0:27:14# Hold me close as I breathe in
0:27:17 > 0:27:21# Close
0:27:26 > 0:27:31# Oh, please break my fall-l-l-l
0:27:34 > 0:27:36# Ohhhh. #
