0:00:02 > 0:00:05Hello and welcome to the home of Techno and Babble.
0:00:05 > 0:00:07They're my new pets. You like?
0:00:07 > 0:00:09Who's a good little girl, then?
0:00:09 > 0:00:14Ugh! You'll get me all rusty. Come on, let's do this.
0:00:30 > 0:00:34Coming up today, Marcus is getting smart to improve his senses.
0:00:34 > 0:00:36I find it a little bit scary, actually.
0:00:36 > 0:00:40Shay's back with more Minecraft tips.
0:00:40 > 0:00:43You know how we all find Endermen terrifying? Right, guys.
0:00:43 > 0:00:46Plus, Jana is here, and she's feeling peckish.
0:00:46 > 0:00:50Food is amazing, and we all love eating at.
0:00:50 > 0:00:53But first, here's an animated Adam to get you all
0:00:53 > 0:00:56excited about the BBC micro:bit.
0:00:58 > 0:01:00No, I love you more. No, I...
0:01:00 > 0:01:05Oh, sorry, I was just talking to my bit on the side. Wahey!
0:01:05 > 0:01:07This is a micro:bit. What is it?
0:01:07 > 0:01:11Well, it's a computer. Yes, a real computer, but it can do anything.
0:01:11 > 0:01:12Well, almost anything.
0:01:12 > 0:01:15I mean, you can't go to the moon with it, but it is still cool.
0:01:15 > 0:01:18It has tons of features, like 25 LED lights that can show messages
0:01:18 > 0:01:22or even emojis. I'm still working on the poo face emoji.
0:01:22 > 0:01:24It has two buttons that you can programme to do different
0:01:24 > 0:01:27things, from controlling games to skipping songs on a playlist.
0:01:27 > 0:01:30It also has a built-in compass so it knows exactly which way
0:01:30 > 0:01:33you are pointing it, and it even has Bluetooth connectivity.
0:01:33 > 0:01:37Here, mate, just been playing with this micro:bit. It is well good.
0:01:37 > 0:01:38I've had a go at making this maze game.
0:01:38 > 0:01:41You have to try and get the flashing dot to the end of the maze
0:01:41 > 0:01:45without touching the sides. Just like this.
0:01:45 > 0:01:47Uh! Oh! Uh!
0:01:47 > 0:01:49- BEEPING - Oh!
0:01:49 > 0:01:51Nice one, Marcus.
0:01:51 > 0:01:53- Anyway, as I was saying... - What's up, boys?
0:01:53 > 0:01:55You know this micro: bit, yeah?
0:01:55 > 0:01:57Well, I've just made a rocket countdown timer.
0:01:57 > 0:02:00I was only trying to send a text, but managed to end up doing this.
0:02:00 > 0:02:05'Five, four, three, two, one.'
0:02:05 > 0:02:08GUITAR RIFF
0:02:08 > 0:02:11Woo! Rock and roll.
0:02:11 > 0:02:13Excuse me, Leila.
0:02:13 > 0:02:17As you can see, you can pretty much make anything. Even a guitar.
0:02:17 > 0:02:20There's loads of pre-codes and fun things on the micro:bit website.
0:02:20 > 0:02:23Have a go at creating your own, or you can even follow tutorials.
0:02:23 > 0:02:25There are three different ways to write your code,
0:02:25 > 0:02:26some harder than others.
0:02:26 > 0:02:30- But everything this lot have made is possible too.- Even I can do it.
0:02:30 > 0:02:33Well, if Jake can micro:bit, then anyone can.
0:02:33 > 0:02:38All right, you lot, get out of my house, go on! Thanks, Adam.
0:02:38 > 0:02:41That was a micro:bit good. Hee!
0:02:41 > 0:02:44Now, I let Techno choose the name for the message app this week.
0:02:44 > 0:02:47Let's see what she went with.
0:02:47 > 0:02:50Catnipbook. Oh, dear. Wow.
0:02:50 > 0:02:53That's even worse than my past suggestions.
0:02:53 > 0:02:56Vlogster, how will technology help disabled people?
0:02:56 > 0:02:58Lovely question there, Nick.
0:02:58 > 0:03:00I need a sensitive soul for this one,
0:03:00 > 0:03:04but I don't think they are available, so Marcus will have to do.
0:03:14 > 0:03:17- Can I get you a drink, sir? - Hi, I'll have a lemonade.
0:03:17 > 0:03:21No, I'll have a water. I'm sorry, I'm a bit nervous.
0:03:21 > 0:03:24I've got a date, and it is all a bit of a mystery.
0:03:24 > 0:03:27- I've just been told to bring this rose.- Oh, how exciting.
0:03:27 > 0:03:28I'll get you a drink.
0:03:28 > 0:03:32- Hey, beautiful!- Oh, go away, Vlogster.
0:03:32 > 0:03:34Not now. I've got a date.
0:03:34 > 0:03:37I know. Pucker up, beautiful!
0:03:37 > 0:03:38VLOGSTER LAUGHS
0:03:38 > 0:03:40God, no, thanks.
0:03:40 > 0:03:42I don't suppose you're going to pay for the dinner either?
0:03:42 > 0:03:47No time for food, Marcus. We have some techsploring to do.
0:03:47 > 0:03:50I'm sending Marcus to Oxford University to meet techspert
0:03:50 > 0:03:52Professor Stephen Hicks.
0:03:52 > 0:03:56He's a neuroscientist who has been working on a pair of glasses
0:03:56 > 0:03:59that are helping blind people to see.
0:03:59 > 0:04:02These look amazing, it looks like I can see through walls with these.
0:04:02 > 0:04:03You can't quite see through walls, but
0:04:03 > 0:04:06if you are partially sighted, these can show you where the walls are.
0:04:06 > 0:04:09And things like people, other things that you might bump into.
0:04:09 > 0:04:11Sounds like these could be potentially life-saving.
0:04:11 > 0:04:14What's it like for partially sighted people when they use these?
0:04:14 > 0:04:17A lot of people who are partially sighted have some sight left.
0:04:17 > 0:04:19Often it can be dark and cloudy,
0:04:19 > 0:04:22and you can mess with all the interesting details of the world.
0:04:22 > 0:04:25Is there anyway I can see what it is like to be partially sighted?
0:04:25 > 0:04:26If you want to try, we've got these here.
0:04:26 > 0:04:28These demonstrate a bit about what it's like
0:04:28 > 0:04:30for one type of blindness.
0:04:30 > 0:04:33I can see shapes, but I can't fully focus on anything.
0:04:33 > 0:04:35We use a central part of our vision to really work out what
0:04:35 > 0:04:38details are, to understand if that's a person you know, to see
0:04:38 > 0:04:40an expression, or to read text.
0:04:40 > 0:04:43I find it a little bit scary, actually.
0:04:43 > 0:04:45- So, shall I try these on now, then?- Yes, sure.
0:04:45 > 0:04:48This'll put an image in the central part of your field of view.
0:04:48 > 0:04:52Wow. So straightaway I can see a lot more detail.
0:04:52 > 0:04:55For example, I can see your face, I can see your glasses.
0:04:55 > 0:04:58I can even see you smiling there as well, and nodding. Wow.
0:04:58 > 0:05:01Yes, hold a few things up. Let me guess. Five. All five of them.
0:05:01 > 0:05:02- Well done.- Oh, Cheers.
0:05:02 > 0:05:05Everything in the background, there's less detail in it.
0:05:05 > 0:05:06- Yeah.- Why is that?
0:05:06 > 0:05:09What we tried to do is focus on the things that are most important.
0:05:09 > 0:05:12And often that's the thing that is closest to you.
0:05:12 > 0:05:14We do that by dropping out all the stuff in the background,
0:05:14 > 0:05:16just focusing on stuff that is right there in front.
0:05:16 > 0:05:19I'd love to go out and about and try these smart specs.
0:05:19 > 0:05:21Yes, we've made these ones so they're really portable.
0:05:21 > 0:05:24It's got a battery pack so you can run around for about six hours.
0:05:24 > 0:05:26Let's do that. I'm well up for that.
0:05:26 > 0:05:29MUSIC: Theme from Jurassic Park
0:05:33 > 0:05:36Wow, this place is amazing. Why have you brought me here?
0:05:36 > 0:05:39To show you that this is a system that you can take outside.
0:05:39 > 0:05:41It is battery powered, so you can take it to a museum,
0:05:41 > 0:05:43- and kind of see more stuff.- Awesome.
0:05:43 > 0:05:45I notice you have made some adjustments as well.
0:05:45 > 0:05:47That's right. This is like a sunglasses module.
0:05:47 > 0:05:49You can put that on the front. It darkens the background.
0:05:49 > 0:05:51You can pay more attention to what's on the screen.
0:05:51 > 0:05:54- Excellent, so I can focus more on what's going on.- Yes.
0:05:54 > 0:05:57- Let's go check out some exhibits, then.- Yes, let's have a look.
0:05:57 > 0:05:59All right, that way.
0:06:12 > 0:06:15I'm not actually seeing through the camera, am I?
0:06:15 > 0:06:16How do these work?
0:06:16 > 0:06:18No, see, you're just seeing what's on this display,
0:06:18 > 0:06:21- what's on the digital display inside your glasses themselves.- Right.
0:06:21 > 0:06:23So, it's taking a representation of the outside world
0:06:23 > 0:06:26and making it really high contrast, so, getting rid of anything else,
0:06:26 > 0:06:29just focusing on something like a big word or a big obstacle.
0:06:29 > 0:06:31It's very fast video, so you should be able to, you know,
0:06:31 > 0:06:33react to things as quickly as normal,
0:06:33 > 0:06:35avoid things when you walk.
0:06:35 > 0:06:36I'm not sure if we can catch a ball yet,
0:06:36 > 0:06:38but, you know, we're working on that.
0:06:40 > 0:06:43I seem to pick up all the shapes.
0:06:43 > 0:06:45- Are you getting some round shapes? - Mm-hmm.
0:06:47 > 0:06:50This is amazing. What can we expect from the future of this technology?
0:06:50 > 0:06:51It's an artificial intelligence,
0:06:51 > 0:06:53to let you know actually what you're looking at,
0:06:53 > 0:06:56and be able to help you find friends, help you understand,
0:06:56 > 0:06:58you know, if that's a bird, what's on the menu.
0:06:58 > 0:06:59We are testing that at the moment.
0:06:59 > 0:07:02I'll tell you what, that's amazing and this has been amazing as well.
0:07:02 > 0:07:04I cannot wait to see this out and about.
0:07:06 > 0:07:08I've lost her, look! Museum shop!
0:07:08 > 0:07:09Time to get some treats!
0:07:09 > 0:07:11I've got a treat for you
0:07:11 > 0:07:14and it doesn't involve novelty pencil rubbers.
0:07:14 > 0:07:17Now for a wheelchair user in the city.
0:07:17 > 0:07:20Swiss students have built a self-balancing wheelchair with
0:07:20 > 0:07:23a track that lowers to climb stairs.
0:07:23 > 0:07:26The inventors hope future versions will be able to master
0:07:26 > 0:07:28a step every second.
0:07:28 > 0:07:30Amazing! What else have you got for me?
0:07:30 > 0:07:35I give you the ReWalker exoskeleton - a wearable robotic suit.
0:07:35 > 0:07:38This tech skeleton helps people with spinal cord injuries
0:07:38 > 0:07:41to walk by controlling their hip and knee movements.
0:07:41 > 0:07:45The system senses subtle changes in the wearer's upper body
0:07:45 > 0:07:48so that walking, turning and climbing stairs happen freely.
0:07:50 > 0:07:54Next up, full-blown Iron Man suit with built-in forcefield,
0:07:54 > 0:07:56rocket shoes and a radar!
0:07:56 > 0:08:00- OK, maybe not. - There's no maybe about it, Marcus!
0:08:00 > 0:08:04Babblers, did I tell you - I learnt to push over sheep the other week.
0:08:04 > 0:08:05SHEEP BLEATS
0:08:05 > 0:08:10No, not real sheep! Please never do that, it's madness and cruel!
0:08:10 > 0:08:12No, I'm talking about Minecraft sheep.
0:08:12 > 0:08:16And here's Chai to give us a compu-torial.
0:08:16 > 0:08:18Today I'm going to be teaching you some tips in Minecraft
0:08:18 > 0:08:20that you may or may not know.
0:08:20 > 0:08:21Number one - the torch trick.
0:08:21 > 0:08:24So, my least favourite thing in the world is
0:08:24 > 0:08:26when I'm looking for my favourite thing in the world, which is
0:08:26 > 0:08:29obviously diamonds, and I hit into sand or gravel.
0:08:29 > 0:08:31So, if you need to get rid of it quickly, just use a torch.
0:08:31 > 0:08:34If you knock out the bottom block of the stack of gravel or sand
0:08:34 > 0:08:36and you quickly placed the torch underneath,
0:08:36 > 0:08:38then the rest will disappear.
0:08:38 > 0:08:40Tip number two - how not to get scared.
0:08:40 > 0:08:42So, you know how we all find Endermen terrifying?
0:08:42 > 0:08:45Right, guys? It's not just me, right?
0:08:45 > 0:08:48Well, if you are terrified of them and you can't sleep at night because
0:08:48 > 0:08:50of them like me, then wear a pumpkin on your head
0:08:50 > 0:08:51when you go mining.
0:08:51 > 0:08:54If you have a pumpkin on your head, the Endermen won't attack you.
0:08:54 > 0:08:57You can even attack them without being attacked in return.
0:08:57 > 0:09:00Number three - you guys know how annoying it is when zombies try
0:09:00 > 0:09:01and break down your door?
0:09:01 > 0:09:03Well, to create a zombie-proof door,
0:09:03 > 0:09:06just raise the block that the door's on by one.
0:09:06 > 0:09:07Simple.
0:09:07 > 0:09:09Well, I hope you guys learned some new tricks today
0:09:09 > 0:09:11and now you can go and use them in your own Minecraft world.
0:09:11 > 0:09:14Thanks, Chai, buddy. Some tip-top top tips there.
0:09:14 > 0:09:15ALARM SOUNDS
0:09:15 > 0:09:18Oh...there's another alert from Catnipbook!
0:09:18 > 0:09:22Vlogster, could people ever walk on water or levitate?
0:09:22 > 0:09:27Ooh, I like how you just floated that one in! Let's see what I can find.
0:09:27 > 0:09:30Turns out researchers have been trying to find ways to help
0:09:30 > 0:09:34you humans for years, looking at animals that already walk on water.
0:09:34 > 0:09:36Like the basilisk lizard.
0:09:36 > 0:09:40These clever little reptiles slap their big fringed feet onto
0:09:40 > 0:09:44the water surface, creating pockets of air to help them stay afloat.
0:09:44 > 0:09:49One tiny problem - a lizard weighs about 200g, which is
0:09:49 > 0:09:52200 times lighter than the average Babbler.
0:09:52 > 0:09:56That means you'd have to run at 67mph, as fast as a cheetah,
0:09:56 > 0:09:58to stay dry.
0:09:58 > 0:10:01But some clever types in Malaysia have created a pool of water
0:10:01 > 0:10:03that people can actually run on.
0:10:03 > 0:10:07Someone has even cycled a bike over it. That's really good!
0:10:07 > 0:10:10The pool isn't filled with just water, though.
0:10:10 > 0:10:14It has 2,000 gallons stirred up with cornstarch.
0:10:14 > 0:10:18When they mix together, the forces of physics means the starch
0:10:18 > 0:10:20and water form a solid when pressure is applied.
0:10:20 > 0:10:24This is why the pool works so well if you run over the mixture,
0:10:24 > 0:10:28but this isn't quite WATER we're after.
0:10:28 > 0:10:32So, do you know it's possible for scientists to levitate a frog?
0:10:32 > 0:10:35Everything around you humans, including frogs,
0:10:35 > 0:10:37is made from tiny particles called atoms.
0:10:37 > 0:10:40When atoms are put in a magnetic field,
0:10:40 > 0:10:44some of the electrons inside them change the way they move around
0:10:44 > 0:10:49and means the frog is essentially made up of lots of tiny magnets, and
0:10:49 > 0:10:54it's this that can help small objects and animals like frogs to levitate.
0:10:54 > 0:10:56We're getting closer! Ribbet.
0:10:56 > 0:11:00In Japan, techsperts have recently developed a levitating train,
0:11:00 > 0:11:04which set a world speed record of 374mph.
0:11:04 > 0:11:06It's all down to magnets too.
0:11:06 > 0:11:09A special magnetised coil runs along the track
0:11:09 > 0:11:13and this repels big magnets on the train's undercarriage,
0:11:13 > 0:11:17making the train levitate ten centimetres above the track.
0:11:17 > 0:11:21And there we have it - a way you humans can levitate.
0:11:22 > 0:11:25Oh-h-h, sorry, viewers. I've missed my lunch.
0:11:25 > 0:11:29Well, I say "missed", what actually happened was that SOMEONE...
0:11:29 > 0:11:33was a very naughty boy and ate my sandwiches when my back was turned!
0:11:33 > 0:11:36No, don't look like that. They were my favourite, egg sandwiches.
0:11:36 > 0:11:39I should know, I keep smelling them on you. Ugh!
0:11:39 > 0:11:41Jana, talk to me.
0:11:42 > 0:11:43Hey, everyone.
0:11:43 > 0:11:46So, if there's one thing that we can all agree on,
0:11:46 > 0:11:49it's that food is amazing and we all love eating it.
0:11:49 > 0:11:53I'm going to tell you about some amazing apps all about food.
0:11:53 > 0:11:56Let's talk about Kitchen Stories.
0:11:56 > 0:12:00I love cooking, as you can tell, but sometimes finding great recipes,
0:12:00 > 0:12:04clear instructions and all the right ingredients can seem impossible.
0:12:04 > 0:12:06Kitchen Stories makes it easy.
0:12:06 > 0:12:09All you have to do is scroll through the recipes
0:12:09 > 0:12:11and choose one that looks extra delicious.
0:12:11 > 0:12:15There you'll find a video tutorial, all of the ingredients you'll need
0:12:15 > 0:12:17and you can add them to a shopping list.
0:12:17 > 0:12:20Then it's time for the hard part - the tasting.
0:12:20 > 0:12:22When you're cooking a meal, you probably have various pots
0:12:22 > 0:12:24and pans on the go, right?
0:12:24 > 0:12:26You'll need Thyme.
0:12:26 > 0:12:28This is a great app which in essence is a timer.
0:12:28 > 0:12:30But it also has options
0:12:30 > 0:12:33so that you can put separate timers for your pots, your pans
0:12:33 > 0:12:36and your oven so that you can run them all simultaneously,
0:12:36 > 0:12:40meaning that you should have perfect meals every time.
0:12:40 > 0:12:43Now, if you don't fancy cooking but you still love to eat great food,
0:12:43 > 0:12:45you'll love Food Spotting.
0:12:45 > 0:12:49It uses your location to show you the best dishes in your area,
0:12:49 > 0:12:53and it's all submitted by people who love food just like you.
0:12:53 > 0:12:57You can even join in by posting a great meal that you've spotted.
0:12:57 > 0:13:00Just take a picture of it and add the location to help
0:13:00 > 0:13:05the people in your area choose the most delicious option on the menu.
