0:00:06 > 0:00:07Time now for Click.
0:00:07 > 0:00:09This week, deep concentration in Malawi, nanotech candyfloss
0:00:09 > 0:00:13in Cambridge, and in Switzerland...
0:00:13 > 0:00:18I have no idea what that is, but I want one.
0:00:56 > 0:01:02I'm looking for something that is thinner than a human hair.
0:01:02 > 0:01:04And that's because nanotech is about building things
0:01:04 > 0:01:07on the nanoscale, up to about 100 nanometres in width, or one 200th
0:01:07 > 0:01:09of the width of a human hair.
0:01:09 > 0:01:24No, I still can't see it.
0:01:24 > 0:01:27It's not in there yet!
0:01:27 > 0:01:27Right!
0:01:27 > 0:01:30That'll be why.
0:01:30 > 0:01:34Last week, we looked at one instance of nanotechnology - graphene.
0:01:34 > 0:01:37Remember, those sheets of carbon that are just one atom thick
0:01:37 > 0:01:48and that have amazing properties.
0:01:48 > 0:01:51Well, now I've come to Cambridge, where researchers seem to be
0:01:51 > 0:01:52pulling nanotech out of the air.
0:01:52 > 0:01:55These are carbon nanotube fibres.
0:01:55 > 0:02:05What we are looking at is carbon-nanotube based fibre.
0:02:05 > 0:02:08So even that is not one carbon nanotube, that's like thousands
0:02:08 > 0:02:09of them entwined.
0:02:09 > 0:02:10Thousands of entangled carbon nanotubes.
0:02:10 > 0:02:13And here in this lab, they've finally cracked how to
0:02:13 > 0:02:15incorporate these tiny tubes into a copper cable to make something
0:02:16 > 0:02:16they're calling UltraWire.
0:02:16 > 0:02:18OK, having a lighter, more conductive copper wire,
0:02:18 > 0:02:28because of the carbon nanotubes inside, who benefits from that?
0:02:28 > 0:02:30The biggest beneficial is the transport industry.
0:02:30 > 0:02:32In a single aeroplane, you may find from a few hundred
0:02:32 > 0:02:43kilograms of copper cables up to five tons of copper cables.
0:02:43 > 0:02:44Wow.
0:02:44 > 0:02:47It would bring huge savings on fuel consumption, it would reduce
0:02:47 > 0:02:48CO2 emission, and who knows?
0:02:48 > 0:02:57Even possibly provide some extra space for your luggage!
0:02:57 > 0:03:01Always about the excess luggage, tell me about it!
0:03:01 > 0:03:06And nowhere will this make more of a difference than in space travel.
0:03:06 > 0:03:08At the moment, it gusts an average of $20,000 to
0:03:08 > 0:03:11send each kilogram of a payload into space on one of these.
0:03:11 > 0:03:14Well, swap out any wiring for something perhaps even half the
0:03:14 > 0:03:17weight, and it's easy to see how everyone from Citroen to Nasa are
0:03:17 > 0:03:23interested in this kind of tech.
0:03:23 > 0:03:26But beyond its weight, the increased conductivity of the
0:03:26 > 0:03:32wire will mean faster data speeds.
0:03:32 > 0:03:34Carbon nanotubes can take many forms,
0:03:34 > 0:03:37so not only do we have these long strands, which are carbon nanotubes,
0:03:37 > 0:03:40or intertwined, we also have a film of carbon nanotubes here, we have
0:03:40 > 0:03:48a powder that is carbon nanotubes.
0:03:48 > 0:03:50This is interesting, these are the scrapings
0:03:50 > 0:03:52from the inside of their furnace!
0:03:52 > 0:03:54They are also carbon nanotubes, and they also work.
0:03:54 > 0:03:56There are thousands of projects now operating on the nanoscale.
0:03:56 > 0:03:59On a more everyday level, nanotech could see the creation
0:03:59 > 0:04:15of clothes that clean themselves.
0:04:15 > 0:04:18Researchers at RMIT university in Melbourne in Australia have ,
0:04:18 > 0:04:20with a cheap way to grow nanostructures directly onto
0:04:20 > 0:04:22textiles that, when exposed to light, degrade organic matter.
0:04:22 > 0:04:26And then there's this, which is a lavatory which does not need water.
0:04:26 > 0:04:28In fact, it produces clean water from what you...put
0:04:28 > 0:04:36in.
0:04:36 > 0:04:39A nano-thick covering seals off any waste material that goes into the
0:04:39 > 0:04:42bowl, preventing any smells, and that waste is passed through a nano
0:04:42 > 0:04:46carbon filter that is so fine that what comes out the other end, so to
0:04:46 > 0:04:52speak, is technically OK to drink.
0:04:52 > 0:04:55Although we are told it does whiff a tiny bit, so you may just want to
0:04:56 > 0:04:59water your plants with it instead.
0:04:59 > 0:05:01Now, obviously, nanotechnology requires you to take
0:05:01 > 0:05:03really, really accurate measurements, and for that you need
0:05:03 > 0:05:04no vibrations, absolute silence.
0:05:04 > 0:05:08Well, LJ Rich has managed to gain access to some really high precision
0:05:08 > 0:05:10research in one of the quietest places on earth.
0:05:10 > 0:05:26This building in Zurich hides a lab unlike any other.
0:05:26 > 0:05:28Welcome to one of the quietest places in the world,
0:05:28 > 0:05:30this is IBM's noise-free labs.
0:05:30 > 0:05:33We are six metres underground, eight metres underground if you count the
0:05:33 > 0:05:36two metres of extra work that's gone on to make this place so quiet.
0:05:36 > 0:05:39And behind these doors, some amazing nanotechnology is taking place,
0:05:39 > 0:05:47and we get to have a look.
0:05:47 > 0:05:48Six labs designed for incredibly sensitive work reside
0:05:48 > 0:05:50in IBM's answer to the Batcave.
0:05:50 > 0:05:52It's taken years to build this place.
0:05:52 > 0:05:54Experiments here are on a truly tiny scale.
0:05:54 > 0:05:55In some cases, manipulating single molecules.
0:05:55 > 0:06:06Noise of any kind has to be supressed.
0:06:06 > 0:06:09So if you start playing around with single molecules, these are
0:06:09 > 0:06:11incredibly small building blocks, typically one nanometre in length,
0:06:11 > 0:06:15and if you want to make contact with single molecules, of course you have
0:06:15 > 0:06:17to work in a very stable environment, because vibrations
0:06:17 > 0:06:26can interact with your molecule.
0:06:26 > 0:06:30Noise-free is not just about damping down sound, though they do down here
0:06:30 > 0:06:31with these sound absorbing tiles.
0:06:31 > 0:06:33There's also magnetic material in the walls and ceiling.
0:06:33 > 0:06:35This prevents electromagnetic fields from entering the room
0:06:35 > 0:06:40and interfering with measurements.
0:06:40 > 0:06:42Even the natural vibration of the earth is cancelled out.
0:06:42 > 0:06:44All the equipment rests on a suspended platforms
0:06:44 > 0:07:02so finely balanced that I can push it with my feet and move 36 tons.
0:07:02 > 0:07:02Pleasing!
0:07:02 > 0:07:05Most of the work here is involved in making transistors smaller.
0:07:05 > 0:07:07They're the building blocks of pretty much every bit of
0:07:07 > 0:07:11technology we use, and it feels like the set of a science-fiction movie.
0:07:11 > 0:07:13In there is an electron lithography machine for making transistors
0:07:13 > 0:07:19at sub five nanometre levels.
0:07:19 > 0:07:20That is absolutely tiny.
0:07:20 > 0:07:22The thing is, it's experimental, so they don't know
0:07:22 > 0:07:23if they're going to work.
0:07:23 > 0:07:26Now, we all know that smaller components mean, eventually,
0:07:26 > 0:07:28smaller tech, but with small tech comes the problem of lots
0:07:28 > 0:07:32of excess heat, which is why work is being done here to explore what
0:07:32 > 0:07:43happens when our gadgets get hot.
0:07:43 > 0:07:44This ultra sensitive thermometer actually touches
0:07:44 > 0:07:47the substance to measure its temperature, which is why the
0:07:47 > 0:07:57noise and vibration-free environment makes for a more reliable reading.
0:07:57 > 0:08:00So if you can better understand and see where the heat is dissipating,
0:08:00 > 0:08:03we may change the device design, and by this we can improve the
0:08:03 > 0:08:06efficiency and the performance of mobile devices, our computers, and
0:08:06 > 0:08:16basically make them operate faster and more energy-efficient.
0:08:16 > 0:08:18Sometimes, to see something small, you need to go big.
0:08:18 > 0:08:21This is a four metre high massive electron microscope that allows you
0:08:21 > 0:08:23to measure at the subatomic level.
0:08:23 > 0:08:25And thanks to the fact that we are in
0:08:25 > 0:08:28a noise-free environment, this thing is the most accurate in the world.
0:08:28 > 0:08:30The microscope excites molecules with a laser
0:08:30 > 0:08:48and measures what happens.
0:08:48 > 0:08:50Here is a bigger version of the experiment.
0:08:50 > 0:08:51As the distance changes between these magnets,
0:08:51 > 0:08:54you can find the exact point at which they zap together.
0:08:54 > 0:08:57But before you, like me, lust after the thought of working somewhere
0:08:57 > 0:08:58completely quiet, here is the catch.
0:08:58 > 0:09:01Lab techs actually spend most of their time here, with all
0:09:01 > 0:09:02the air-conditioning units.
0:09:02 > 0:09:04This is the room which keeps everything constant.
0:09:04 > 0:09:06Specially built temperature maintenance systems, electronics,
0:09:06 > 0:09:08and basically anything noisy is kept in this room.
0:09:08 > 0:09:10And all the experiments are done with the scientists outside
0:09:10 > 0:09:13the quiet room, because, well, even humans make quite
0:09:13 > 0:09:16a din with all that breathing, heat and everything else we generate.
0:09:16 > 0:09:21Wow!
0:09:21 > 0:09:24Well, it is pretty obvious to me that a lot of the stuff going
0:09:24 > 0:09:29on here is, you know, ten, 20 years in the future.
0:09:29 > 0:09:32Meanwhile, it's time for me to go back to the noisy world upstairs.
0:09:32 > 0:09:35That was LJ, and as LJ says, nanotech research takes time.
0:09:35 > 0:09:37This is Bojan Boskovic, the boss of the company set up to
0:09:37 > 0:09:40make the most of nanotech research here in Cambridge and elsewhere.
0:09:40 > 0:09:43I think a lot of people, when they hear the word "nanotechnology",
0:09:43 > 0:09:46think of tiny robots and tiny motors the size of molecules.
0:09:46 > 0:09:57Should we be thinking like that?
0:09:57 > 0:09:59Well, we're pretty much there with the size wise,
0:09:59 > 0:10:01so the size of the smallest carbon nanotube, single-walled carbon
0:10:01 > 0:10:04nanotube, is already in the range of the DNA molecule.
0:10:04 > 0:10:07So we're not going to get much smaller than the atomic level,
0:10:07 > 0:10:10and what is going to happen, those molecules and atoms, we will
0:10:10 > 0:10:13learn how to manipulate them, and that is all about nanotechnology
0:10:13 > 0:10:14engineering, at the nanoscale.
0:10:14 > 0:10:17So we will learn to use them, but probably robots like we think
0:10:17 > 0:10:31of small tiny parts going inside, it's not going to happen.
0:10:31 > 0:10:34But could you make cogs and motors that are the size of molecules?
0:10:34 > 0:10:35Yes, yes, yes.
0:10:35 > 0:10:38And put them together into something very tiny that could
0:10:38 > 0:10:39be called a machine?
0:10:39 > 0:10:43It could be, it could be, and we will see more and more tiny
0:10:43 > 0:10:46machines, but the real stuff is not probably going to be machines
0:10:46 > 0:10:49in the sense that we think it now, of a lot of mechanical parts.
0:10:49 > 0:10:52It is going to be what we call molecular machines,
0:10:52 > 0:10:54so clever molecules doing things the way how we want.
0:10:54 > 0:10:57It could be a drug-delivery vehicle, for delivering drugs exactly to
0:10:57 > 0:10:59the cell that we need it.
0:10:59 > 0:11:01They can also use, be used to kill the cancer cells,
0:11:01 > 0:11:03rather than shooting in the dark.
0:11:03 > 0:11:06Many things would be basically far more precise and far more
0:11:06 > 0:11:24controlled, and that's the way how the nanotechnology is taking us.
0:11:24 > 0:11:27In this week's tech news, one of the Old Masters, Rembrandt,
0:11:27 > 0:11:28makes a return with a new painting.
0:11:28 > 0:11:31Or at least, a computer has analysed and copied his style.
0:11:31 > 0:11:34A team of Dutch researchers, with help from Microsoft, have created
0:11:34 > 0:11:36a Rembrandt style image using a 3D-printing paint technique.
0:11:36 > 0:11:39The 3D printing creates the same texture as an oil painting.
0:11:39 > 0:11:42It was the week that Chinese outfit Huawei launched a brand-new phone
0:11:42 > 0:11:52fitted with two cameras on the back.
0:11:52 > 0:11:54Like Lytro cameras, the P9 smartphone is capable
0:11:54 > 0:12:05of refocusing part of an image after a photo has been taken.
0:12:05 > 0:12:08And it was also the week that games giant Valve found a new use
0:12:08 > 0:12:11for virtual reality, as a means of allowing e-sports spectators to
0:12:11 > 0:12:18get a whole new VR perspective on competitive gaming events.
0:12:18 > 0:12:21Next, have you ever wished that your web browser was more complicated?
0:12:21 > 0:12:22You have?
0:12:22 > 0:12:24Well, then the Vivaldi browser, designed for power users,
0:12:24 > 0:12:25could be for you.
0:12:25 > 0:12:28It's the brainchild of one of the guys behind the Opera browser.
0:12:28 > 0:12:30Instead of stripping back features for simplicity, Vivaldi is
0:12:30 > 0:12:33customisable to a mind-boggling degree, allowing users to have stuff
0:12:33 > 0:12:51bursting out of every corner of the screen - if that is what they like.
0:12:51 > 0:12:55Right, next, we're off to Malawi in Africa, and to a clever scheme
0:12:55 > 0:12:57that we've reported on before.
0:12:57 > 0:13:00We visited a school in Lilongwe, which had just been introduced to
0:13:00 > 0:13:0430 tablets used to teach the children maths.
0:13:04 > 0:13:07And the results were really startling, so much so that the same
0:13:07 > 0:13:14tablets and apps are now being used in the UK with similar results.
0:13:14 > 0:13:17Well, that the small scheme has grown at a phenomenal pace
0:13:17 > 0:13:18since we first visited.
0:13:18 > 0:13:34Dan Simmons has been back to Malawi to see what's new.
0:13:35 > 0:13:37BELL RINGS.
0:13:37 > 0:13:39This is the primary school, one of the busiest in
0:13:39 > 0:13:40the whole of Malawi.
0:13:40 > 0:13:42There are 9000 pupils attending this primary school,
0:13:42 > 0:13:44and classes of up to 250, which makes teaching,
0:13:44 > 0:13:45well, quite a challenge.
0:13:45 > 0:13:47It makes getting through the playground quite
0:13:47 > 0:13:48a challenge as well!
0:13:48 > 0:13:49Hello, hi!
0:13:49 > 0:13:50Hi!
0:13:50 > 0:13:54It is seven o'clock, and the first shift of school begins.
0:13:54 > 0:13:57These children will either come for the morning or the afternoon,
0:13:57 > 0:14:00because you can't teach 9,000 kids otherwise.
0:14:00 > 0:14:03First class of the day -
0:14:03 > 0:14:08how to deal with 100 schoolkids wanting to shake hands!
0:14:09 > 0:14:13This teacher is brilliant, she's fun, engaging, authoritative.
0:14:13 > 0:14:18Even though it's maths, she manages to hold the children's attention.
0:14:18 > 0:14:22Well, most of them, anyway.
0:14:22 > 0:14:25But she can't monitor what they've written down -
0:14:25 > 0:14:27whether it's legible, whether they're all keeping up -
0:14:27 > 0:14:32and after this there will be another class of 80.
0:14:32 > 0:14:35The classes are so large here, many are held outside.
0:14:36 > 0:14:38If it rains, school is off.
0:14:38 > 0:14:42A few years back, Malawi made primary education open to all,
0:14:42 > 0:14:48before it had enough schools to cope, and it still doesn't.
0:14:48 > 0:14:50In the last year or so,
0:14:50 > 0:14:54a different kind of classroom has been popping up across Malawi.
0:14:54 > 0:14:59It's very much shoes off and time to plug in.
0:14:59 > 0:15:02Everything is really quiet,
0:15:02 > 0:15:07because everyone's wearing headphones.
0:15:07 > 0:15:11The UK's VSO charity is working with onebillion.org
0:15:11 > 0:15:15and 68 schools to teach maths and, this year, the local language,
0:15:15 > 0:15:19Chichewa, as well as English, to four and five-year-olds.
0:15:19 > 0:15:24And when someone does well, the whole class knows about it.
0:15:24 > 0:15:27What it does mean is that, for the first time here,
0:15:27 > 0:15:30teachers are able to monitor every pupil's progress.
0:15:30 > 0:15:33Staff at the school or back in the UK can watch
0:15:33 > 0:15:37what works and tweak the lessons to get better results.
0:15:37 > 0:15:40Early analysis by independent universities suggests this method
0:15:40 > 0:15:45is hugely effective and it needs to be, because each child enrolled
0:15:45 > 0:15:50gets just two half-hour sessions in this room each week.
0:15:50 > 0:15:52This is a big deal.
0:15:52 > 0:15:55Reading even one sentence after two years' schooling has proven
0:15:55 > 0:15:58a challenge for most children.
0:15:58 > 0:16:01This British project has set its sights on teaching more
0:16:01 > 0:16:04than 20,000 children here how to read complete books
0:16:04 > 0:16:09in their own language by the time they leave.
0:16:10 > 0:16:12And how about this for interactive lessons?
0:16:12 > 0:16:15This project it is the first in the country,
0:16:15 > 0:16:20maybe even the continent, to run off a solar panel.
0:16:20 > 0:16:25Using sunlight is a classic African answer to an African problem,
0:16:25 > 0:16:29but the key thing with this project is the projector uses very low
0:16:29 > 0:16:34power, so three hours' worth of exposure to the sun
0:16:34 > 0:16:38will give these guys three days' worth of lessons.
0:16:38 > 0:16:41Every school in the area now wants one of these projectors,
0:16:41 > 0:16:46because the electricity here is so unreliable.
0:16:46 > 0:16:48Now, you might think Malawi, being one of the poorest ten
0:16:48 > 0:16:52countries in the world, doesn't have much to boast about,
0:16:52 > 0:16:56but directly across the valley is Lilongwe's new $70 million
0:16:56 > 0:17:00stadium, being built and paid for by the Chinese -
0:17:00 > 0:17:04a loan for Malawi to pay back.
0:17:04 > 0:17:06It sticks in the throat a little that those
0:17:06 > 0:17:09on this side of the valley have to pump their own water
0:17:09 > 0:17:11and now make their own electricity.
0:17:11 > 0:17:16But the marriage of self-sufficiency and technology is hugely empowering.
0:17:16 > 0:17:18Unlike the yet to be opened stadium,
0:17:18 > 0:17:23any power cuts here won't be stopping work.
0:17:31 > 0:17:33It doesn't take being part of a generation
0:17:33 > 0:17:36who grew up with smartphones, social networks
0:17:36 > 0:17:40and surfing the web to be making the most of life online.
0:17:40 > 0:17:43One example of a growing number of apps and websites aimed
0:17:43 > 0:17:47at the old market is Stitch, which has been referred to as Tinder
0:17:47 > 0:17:50for the over 50s.
0:17:50 > 0:17:55Nicole met her partner a few months ago using the app.
0:17:55 > 0:17:59I think, within about two days, I'd stitched with someone,
0:17:59 > 0:18:01which meant that we'd both seen each others' profiles
0:18:01 > 0:18:02and we both liked each other.
0:18:02 > 0:18:06That meant we could talk to each other via the messaging service
0:18:06 > 0:18:09on there, we started messaging, and then we rang each other
0:18:09 > 0:18:11on Christmas Eve to see how we would get along
0:18:11 > 0:18:13speaking on the phone.
0:18:13 > 0:18:16And, of course, there's always a little bit of anxiety, I'm sure,
0:18:16 > 0:18:18when you meet someone you haven't met before, but there
0:18:18 > 0:18:21is a sort of verification process with this app,
0:18:21 > 0:18:23isn't there, that doesn't exist with all dating sites?
0:18:23 > 0:18:27Yes, when you join to be a verified member, you have to show that you've
0:18:27 > 0:18:28got another profile somewhere else -
0:18:28 > 0:18:31on Facebook or LinkedIn, so you've got that little bit
0:18:31 > 0:18:36of security there that the person is a real person.
0:18:37 > 0:18:40And there is a stricter level of identification to become
0:18:40 > 0:18:43what they call a trusted member, but for Nicole the app overcame one
0:18:43 > 0:18:48of her great irritations.
0:18:48 > 0:18:50Well, Stitch is for over 50s.
0:18:50 > 0:18:54The major thing with other dating websites is that the men, generally,
0:18:54 > 0:18:58seem to want women who are about 20 or 30 years younger than themselves.
0:18:58 > 0:19:01At least if you go onto Stitch, you know that everyone
0:19:01 > 0:19:03is going to be over 50.
0:19:03 > 0:19:05You also actually meeting up with some other people
0:19:05 > 0:19:08that you've met as a community through the app, haven't you?
0:19:08 > 0:19:10That is right, since I've met the person that I'm now seeing,
0:19:10 > 0:19:13I've changed my profile, so I don't see people
0:19:13 > 0:19:15who are looking for dates now.
0:19:15 > 0:19:18But I can still see people that want to be friends, and
0:19:18 > 0:19:20I can also join in the discussions, the book groups,
0:19:20 > 0:19:21and the different forums.
0:19:21 > 0:19:24So we decided it might be quite fun to actually meet,
0:19:24 > 0:19:31and so we're planning a trip to Vegas in June or July.
0:19:31 > 0:19:33And here is something aimed at older adults whose focus is less
0:19:33 > 0:19:38on new people but more about engaging in a more meaningful
0:19:38 > 0:19:41way with their loved ones.
0:19:41 > 0:19:45The Kindeo app creates an easy way of filming and storing videos
0:19:45 > 0:19:49of important moments of your life, so the experience prompts
0:19:49 > 0:19:53you to answer specific questions about each area of your life,
0:19:53 > 0:19:56so there's family, childhood, work, places, friends.
0:19:56 > 0:20:03And once you tap on them, you'll go through a list of questions.
0:20:03 > 0:20:05We all experience relatives and family getting older,
0:20:05 > 0:20:08and it's very difficult thing to talk about sometimes.
0:20:08 > 0:20:10What Kindeo does is give people a really easy way
0:20:10 > 0:20:16to express how they are feeling.
0:20:16 > 0:20:19For anyone who feels they are no spring chicken,
0:20:19 > 0:20:22here is a website that might be able to help.
0:20:22 > 0:20:25It's a place where learning mindfulness, tips on overcoming
0:20:25 > 0:20:29loneliness, shopping and exercise advice come together.
0:20:29 > 0:20:34The team, aged from 18 to 82, keep it up to date
0:20:34 > 0:20:39with the latest products and ideas tailored towards seniors.
0:20:39 > 0:20:41Begin to inhale...
0:20:41 > 0:20:44And after all that screen time, with over 180,000 downloads,
0:20:44 > 0:20:49Tai Chi for Seniors is one of many apps encouraging
0:20:49 > 0:20:51you to get on your feet,
0:20:51 > 0:20:58providing a spot of clearly explained gentle exercise.
0:21:04 > 0:21:08Look into my eyes.
0:21:08 > 0:21:11Go one, I dare you.
0:21:11 > 0:21:14Yes, they're not that practical, but these glasses are just one
0:21:14 > 0:21:18of a number of crazy inventions recently shown off at the very first
0:21:18 > 0:21:25IBM Mad Scientists evening.
0:21:25 > 0:21:28It had everything from soap dispensers that talk to you to
0:21:28 > 0:21:30boxes that send messages into space.
0:21:30 > 0:21:34No, not that box - this box.
0:21:34 > 0:21:36All designed to attract kids of all ages and show
0:21:36 > 0:21:40the fun side of coding.
0:21:46 > 0:21:50They are testers, they write books, they write code, they are IT
0:21:50 > 0:21:52specialists, they are programmers, those sorts of people,
0:21:52 > 0:21:56all sorts of stuff, and we thought it would be good if we could show
0:21:56 > 0:22:00these guys some of the cool stuff that we've done.
0:22:00 > 0:22:03And it doesn't get much cooler than a BB-8 unit
0:22:03 > 0:22:07controlled by the power of the mind.
0:22:07 > 0:22:10You think of a song... I think of a song.
0:22:10 > 0:22:14And it goes in a certain direction. And it goes in a certain direction.
0:22:14 > 0:22:15Do you realise how insane that sounds?
0:22:15 > 0:22:20Completely insane, but it's part of the event.
0:22:20 > 0:22:22So you think of a song and it goes one way,
0:22:22 > 0:22:24how do you get it to turn round?
0:22:24 > 0:22:27By smiling.
0:22:27 > 0:22:30That's just mad!
0:22:30 > 0:22:33Luke's brainwaves are actually being analysed by a system
0:22:33 > 0:22:38that is taking signals from his headset and then
0:22:38 > 0:22:41interpreting them using a Raspberry Pi.
0:22:41 > 0:22:44Those commands are then transferred via Bluetooth to BB-8,
0:22:44 > 0:22:50although it's much more fun to say that Luke is using the Force.
0:22:51 > 0:22:54But if you can't get something to move with your mind,
0:22:54 > 0:23:00then how about controlling a drone using a tweet.
0:23:02 > 0:23:06Good, trick zone, OK, let's do a backflip, OK, right.
0:23:12 > 0:23:15This project teaches kids the importance of accuracy
0:23:15 > 0:23:18in programming, both in spelling the commands correctly and in
0:23:18 > 0:23:22fully testing things before deployment.
0:23:22 > 0:23:24I'll tell you what, just for a laugh, I'm going to fly
0:23:24 > 0:23:27into the camera now.
0:23:31 > 0:23:36Got you!
0:23:39 > 0:23:42And I will leave you with a dance floor that is controlled
0:23:42 > 0:23:43using Twitter.
0:23:43 > 0:23:44Why?
0:23:44 > 0:23:46Because.
0:23:46 > 0:23:49So anyone can change the pattern on it just by sending commands so...
0:23:49 > 0:23:52# Come and get your love... #
0:23:52 > 0:23:56Or you can send texts, which it will display too,
0:23:56 > 0:24:00and I can't foresee any problem with that whatsoever.
0:24:00 > 0:24:03So that it from the mad scientists at IBM, thank you for watching.
0:24:03 > 0:24:07You can follow us on Twitter throughout the week @BBCClick.
0:24:07 > 0:24:09That worked, see?
0:24:09 > 0:24:11Brilliant, see you soon!
0:24:36 > 0:24:37Good morning.
0:24:37 > 0:24:39If you were lucky enough to have spring sunshine yesterday,
0:24:39 > 0:24:41you probably got some spring warmth as well.
0:24:41 > 0:24:44In fact, it was beautiful - warmest day of the year
0:24:44 > 0:24:46so far across England and Wales.
0:24:46 > 0:24:49We had highs of 19 degrees.
