0:00:02 > 0:00:04MUSIC PLAYS THROUGH EARPHONES
0:00:04 > 0:00:07All right. Don't bore us. Get to the chorus!
0:00:07 > 0:00:08Now!
0:00:24 > 0:00:27This week on Click, we're using data from the dancefloor
0:00:27 > 0:00:31to build the ultimate dance anthem, live.
0:00:31 > 0:00:33Should be right up my street.
0:00:33 > 0:00:35We take a look at the smartphone tech
0:00:35 > 0:00:38that's helping people with autism cope with anxiety.
0:00:38 > 0:00:42And we have some fresh developments in food labelling
0:00:42 > 0:00:45that should stop you munching on mush. Plus we'll bring you
0:00:45 > 0:00:49some very random moments from your past, in Webscape.
0:00:53 > 0:00:55Welcome to Click. I'm Spencer Kelly.
0:00:55 > 0:00:58And welcome to the London Science Museum.
0:00:58 > 0:01:01We're here because Click and this other famous institution
0:01:01 > 0:01:04are teaming up for a unique experiment. Come on.
0:01:05 > 0:01:09We talk a lot on this programme about data analysis
0:01:09 > 0:01:12and crowdsourcing and its myriad applications.
0:01:12 > 0:01:15But we did want to have a play ourselves.
0:01:15 > 0:01:20So we're putting on our own democratic dance event in this room.
0:01:20 > 0:01:22Now, that over there is LJ Rich. You probably recognise her
0:01:22 > 0:01:25from all the music hacking she's done for us over the years.
0:01:25 > 0:01:27She's been very busy over the last few weeks
0:01:27 > 0:01:30trying to use the power of coding
0:01:30 > 0:01:34to scientifically create the ultimate dance anthem.
0:01:34 > 0:01:37LJ, hit it.
0:01:37 > 0:01:38DANCE MUSIC PLAYS
0:01:40 > 0:01:42Who knows more when it comes to music -
0:01:42 > 0:01:44the composer,
0:01:44 > 0:01:46the performer,
0:01:46 > 0:01:48the audience?
0:01:48 > 0:01:51It's a question I've been obsessed with for a while.
0:01:51 > 0:01:55Dance music's all about making people feel good,
0:01:55 > 0:01:57and if the audience could control the music,
0:01:57 > 0:01:59maybe we'd learn something.
0:01:59 > 0:02:04Perhaps we could use that data to make the ultimate floorfiller.
0:02:04 > 0:02:08That data could help to compose some epic tunes
0:02:08 > 0:02:11that I think people would universally enjoy.
0:02:11 > 0:02:13I blogged about my quest,
0:02:13 > 0:02:17and thus the Democratic Dance Music experiment was born.
0:02:19 > 0:02:22Time to enlist some fellow hackers on my musical journey.
0:02:27 > 0:02:30The Dance For Science Alliance.
0:02:30 > 0:02:33First up, my crude analysis of commercial dance tracks
0:02:33 > 0:02:36with a wide appeal. Yep, spreadsheets!
0:02:36 > 0:02:40The most popular tracks were slower than I thought -
0:02:40 > 0:02:43between 125 and 129 beats per minute.
0:02:43 > 0:02:48I also collected data on the kinds of sounds and song structures
0:02:48 > 0:02:50common to the most popular tracks.
0:02:50 > 0:02:54Among other things, these songs all have a theme...
0:02:54 > 0:02:57a build...
0:02:57 > 0:02:59and a drop.
0:02:59 > 0:03:04So I composed some tunes based on my analysis.
0:03:04 > 0:03:07These tunes go to Adam.
0:03:07 > 0:03:10His programme will play a specific piece of each track.
0:03:10 > 0:03:14Which piece depends on commands sent by Rob's machine.
0:03:14 > 0:03:17Now, Rob's computer should let dancers
0:03:17 > 0:03:20press a button on their mobile screen to control the music.
0:03:20 > 0:03:24When 80% of the audience press a button on their phone screen,
0:03:24 > 0:03:27a command goes to Adam's machine to trigger the drop,
0:03:27 > 0:03:30or introduce the bass, in more formal language.
0:03:30 > 0:03:34Emi is working on a generative visual display
0:03:34 > 0:03:36based on the output from Adam's computer.
0:03:36 > 0:03:39It's a mammoth undertaking.
0:03:39 > 0:03:41It's going to be amazing.
0:03:41 > 0:03:44But there's a lot that could go wrong.
0:03:46 > 0:03:48A few weeks in, and we're checking out the space.
0:03:48 > 0:03:52Turns out the Science Museum has a rather spiffing sound system.
0:03:52 > 0:03:54Techies David and John hook us up
0:03:54 > 0:03:57while we each work on our respective areas.
0:03:57 > 0:04:00And before we know it, the event is upon us.
0:04:00 > 0:04:03Word has got out about our little experiment,
0:04:03 > 0:04:06and attendance is nearly a third higher than usual.
0:04:06 > 0:04:10There's clearly something about my idea that, er, strikes a chord.
0:04:10 > 0:04:12You have a sort of narrow band
0:04:12 > 0:04:14in which you want to keep your listeners.
0:04:14 > 0:04:16When people know that the drop is going to happen,
0:04:16 > 0:04:19that will be more pleasurable than when they don't know.
0:04:19 > 0:04:21Raising their level of arousal
0:04:21 > 0:04:24and then subsequently bringing them back down
0:04:24 > 0:04:26to a kind of warm homely feeling
0:04:26 > 0:04:30where they feel that their expectations have been confirmed.
0:04:30 > 0:04:32And expectations are high.
0:04:32 > 0:04:35A month's solid work, and we still haven't had a chance
0:04:35 > 0:04:38to fully test our six-computered, eight-handed hack.
0:04:38 > 0:04:40It's 40 minutes to go.
0:04:40 > 0:04:42We are trying to finish all of the coding,
0:04:42 > 0:04:45all of the cutting up of the pieces and everything
0:04:45 > 0:04:48before the public come in and start experimenting with us.
0:04:48 > 0:04:52Er...I'm actually terrified,
0:04:52 > 0:04:55and I'm also really super-excited at the same time.
0:04:55 > 0:04:57Just have to hope everything's working!
0:04:59 > 0:05:01Time to load our audience.
0:05:01 > 0:05:03We're asking them to connect to our network
0:05:03 > 0:05:06and keep a finger pressed on their smartphone screen.
0:05:06 > 0:05:08We'll track the motion sensor on their phone,
0:05:08 > 0:05:11and from that derive the "wiggle index".
0:05:12 > 0:05:14'People will be able to control the music
0:05:14 > 0:05:16'when the drop button becomes available.
0:05:16 > 0:05:18'But...oh, no.'
0:05:18 > 0:05:21I think we've actually got more than eight people participating.
0:05:21 > 0:05:25'I sense a tiny problem with our system.'
0:05:25 > 0:05:29Oh, er, the wifi is being broadcast from a laptop,
0:05:29 > 0:05:33and when people are trying to join, everyone's kicking each other off,
0:05:33 > 0:05:35and it seems to be capping out at about eight.
0:05:35 > 0:05:37It even kicked off our laptop here that's running on the screens.
0:05:37 > 0:05:42If you can't get online, don't worry - we're sorting it out.
0:05:42 > 0:05:44OK. We've done our first session.
0:05:44 > 0:05:47Our wifi fell over, predictably enough.
0:05:47 > 0:05:49I mean, when you're working with so many different things
0:05:49 > 0:05:52and there's not enough time to get those redundancies checked out,
0:05:52 > 0:05:54things are bound to go wrong.
0:05:54 > 0:05:56But the show must go on.
0:05:56 > 0:05:58It's not my first time on one of these stages,
0:05:58 > 0:06:00and we're actually 80% working.
0:06:00 > 0:06:03I have a contingency plan - manual measurement.
0:06:07 > 0:06:11So, essentially, we're now doing what DJs do -
0:06:11 > 0:06:13reading signals from the crowd - albeit more overtly.
0:06:13 > 0:06:16Everything else works, the visuals look great,
0:06:16 > 0:06:18and the crowd seem to like the music.
0:06:18 > 0:06:22Every time we do a project that's something that's never been done,
0:06:22 > 0:06:24we realise halfway through, "There's a reason
0:06:24 > 0:06:27"why no-one's ever done this - because it's so difficult."
0:06:27 > 0:06:29But, er...people are still really getting into it
0:06:29 > 0:06:32and we're getting usable data, which is what we were after,
0:06:32 > 0:06:33so I'm pretty pleased.
0:06:33 > 0:06:36On the night, maybe we couldn't do the actual mobile phone things,
0:06:36 > 0:06:39but we've still got some useful research.
0:06:39 > 0:06:41And we're going to try it again.
0:06:41 > 0:06:43'Much of that useful research
0:06:43 > 0:06:46'is how to make this work better for next time.
0:06:46 > 0:06:48'Essentially, we beta-tested in public.
0:06:48 > 0:06:52'We are optimistic that we can find the elusive wiggle index,
0:06:52 > 0:06:55'so we're planning on giving the Dance For Science Alliance
0:06:55 > 0:06:59'another outing. After all, we can't keep this guy waiting forever.'
0:07:02 > 0:07:05LJ Rich. And a few technical glitches are to be expected,
0:07:05 > 0:07:08of course, when you are that close to the cutting edge of science.
0:07:08 > 0:07:11Don't worry - LJ and her team of hackers will be back soon,
0:07:11 > 0:07:15so watch this space. Actually, coding and tech development
0:07:15 > 0:07:18can sometimes be more about the journey than the destination.
0:07:18 > 0:07:21Talking of which...
0:07:21 > 0:07:25this super-smooth video of a New York walk
0:07:25 > 0:07:29has been created using Instagram's new app Hyperlapse.
0:07:30 > 0:07:34It is really hard to keep a camera dead steady as it is,
0:07:34 > 0:07:38but over a journey of a number of minutes it's even harder.
0:07:38 > 0:07:41Well, Hyperlapse uses some pretty clever processing
0:07:41 > 0:07:44to produce a much more watchable result.
0:07:44 > 0:07:46Once you've recorded your journey,
0:07:46 > 0:07:50you can decide how fast you want the final video to run.
0:07:50 > 0:07:53Now, the app itself looks pretty simple,
0:07:53 > 0:07:56but what's going on behind the scenes inside your smartphone
0:07:56 > 0:07:58is actually quite impressive.
0:07:58 > 0:08:01When video footage shakes, if you think about it,
0:08:01 > 0:08:04the middle part of the picture stays pretty similar.
0:08:04 > 0:08:07So by zooming in a bit and twisting a bit when you need to
0:08:07 > 0:08:10and then getting rid of all those wobbly edges,
0:08:10 > 0:08:14you can create smooth, albeit slightly lower resolution, video.
0:08:14 > 0:08:18Now, this kind of technology has been available on computers
0:08:18 > 0:08:23for a while. That's why Click looks so fantastically smooth every week.
0:08:23 > 0:08:27The smartphone version, though, has an extra trick up its sleeve,
0:08:27 > 0:08:30by mixing in data from the phone's built-in gyroscope
0:08:30 > 0:08:33as well as analysing the video footage.
0:08:33 > 0:08:36And because you're speeding the video up,
0:08:36 > 0:08:40the app can throw away frames which would make the end result shaky,
0:08:40 > 0:08:43giving those videos a ghostly smoothness.
0:08:43 > 0:08:45This is not a video sharing app.
0:08:45 > 0:08:48This is actually a creative tool that you can use with Instagram
0:08:48 > 0:08:50or with other social networks.
0:08:50 > 0:08:52The idea was that it was a fantastic creative tool
0:08:52 > 0:08:54that was created as a hack in our office.
0:08:54 > 0:08:57Engineers just started playing with our technology,
0:08:57 > 0:08:58and found a really good method of using it.
0:08:58 > 0:09:01You've previously needed really high-powered technology,
0:09:01 > 0:09:04not a smartphone, to do this, and this was the test
0:09:04 > 0:09:06that came alongside the video compression technology
0:09:06 > 0:09:09that we already had in Instagram. And when you link the two together,
0:09:09 > 0:09:12you've got this really fantastic creative tool.
0:09:12 > 0:09:13And that's how this was born.
0:09:13 > 0:09:18It looks like Instagram is trying to steal a march on Apple's iOS 8,
0:09:18 > 0:09:22due out this autumn, which also touts a timelapse feature.
0:09:22 > 0:09:25Microsoft has also demo-ed a similar technology a few weeks ago,
0:09:25 > 0:09:30and it says it's working on putting it in an app for Windows phones.
0:09:30 > 0:09:33Instagram does plan to release an Android version of its app,
0:09:33 > 0:09:36but until then, you will have to have an iPhone
0:09:36 > 0:09:39to create your Hyperlapses.
0:09:41 > 0:09:43Very cool, and we'd love to see
0:09:43 > 0:09:46what you can do with this kind of feature.
0:09:46 > 0:09:48So tweet us @bbcclick
0:09:48 > 0:09:51or email your results to click@bbc.co.uk
0:09:51 > 0:09:54Next up, a look at this week's tech news.
0:09:54 > 0:09:57A safety advisor at Facebook is going to call on the company
0:09:57 > 0:10:01to introduce safeguards to prevent users coming across gruesome images.
0:10:01 > 0:10:05Users have complained about violent images from a part of Syria
0:10:05 > 0:10:07controlled by the jihadist group Islamic State.
0:10:07 > 0:10:10Facebook initially refused to delete the images,
0:10:10 > 0:10:13saying they didn't contravene its guidelines,
0:10:13 > 0:10:16but later blocked the material after being contacted by the BBC.
0:10:16 > 0:10:20Google has shown off delivery drones it's been developing
0:10:20 > 0:10:23in secret for two years.
0:10:23 > 0:10:27Project Wing could rival Amazon's delivery drone plans,
0:10:27 > 0:10:28announced last year.
0:10:28 > 0:10:31Google says the longer-term goal is to use the drones
0:10:31 > 0:10:34to drop disaster relief into isolated areas.
0:10:34 > 0:10:37Project Wing came out of Google's
0:10:37 > 0:10:39clandestine research centre Google X,
0:10:39 > 0:10:43where its autonomous car was also developed.
0:10:43 > 0:10:48And you can finally achieve that perfect dog point-of-view video
0:10:48 > 0:10:50with the Fetch, from GoPro.
0:10:50 > 0:10:54The harness securely holds a GoPro camera on a dog's back or chest
0:10:54 > 0:10:57if they weigh between 15 and 120 lbs.
0:10:57 > 0:11:01No fur is pinched, and it has padded adjustment points.
0:11:01 > 0:11:04But please do note, it's not designed for cats,
0:11:04 > 0:11:07so no cat videos, please.
0:11:11 > 0:11:13We've all been in situations which make us nervous,
0:11:13 > 0:11:16but for a person living with autism,
0:11:16 > 0:11:20noisy, busy environments can cause overwhelming anxiety.
0:11:20 > 0:11:23But researchers at the University of Lancaster
0:11:23 > 0:11:25have been working on a device which may just help,
0:11:25 > 0:11:28and Victoria Gill has been to meet them.
0:11:28 > 0:11:30Just mopping the cup, son.
0:11:30 > 0:11:33'Like one in every hundred people in the UK,
0:11:33 > 0:11:37'Valerie lives with autism.
0:11:37 > 0:11:40'She was diagnosed 15 years ago at age 37,
0:11:40 > 0:11:42'so it was only at that point she realised what it was
0:11:42 > 0:11:45'that affected how she made sense of the world.'
0:11:46 > 0:11:50'Having autism can make my life difficult.
0:11:50 > 0:11:53'I sometimes do not understand what people are saying to me.'
0:11:53 > 0:11:56I don't know where we're all going to sit, though.
0:11:56 > 0:11:58'When I am going somewhere new
0:11:58 > 0:12:01'or doing something I have never done before,
0:12:01 > 0:12:06'I start to think about it too much and start to get worried.
0:12:06 > 0:12:10'Going out in the community can be difficult for me.'
0:12:10 > 0:12:14A trip to the shops is something a lot of us just take in our stride,
0:12:14 > 0:12:17but for many people who live with autism, the unpredictability
0:12:17 > 0:12:21of a high street like this can be a source of huge anxiety.
0:12:21 > 0:12:25So what if there was something that many of us keep with us all the time,
0:12:25 > 0:12:28that could alleviate this social stress?
0:12:29 > 0:12:33Researchers at Lancaster University have combined what looks like
0:12:33 > 0:12:37a stress ball, a pressure-sensitive squeezable game controller,
0:12:37 > 0:12:40with a smartphone app to develop a prototype piece of technology
0:12:40 > 0:12:45that could help people escape episodes of crippling social anxiety.
0:12:46 > 0:12:51The squeezy ball is connected via Bluetooth to the smartphone.
0:12:51 > 0:12:54And the smartphone can be put away in your handbag or your pocket,
0:12:54 > 0:12:58and then whenever you pick this up and start using it
0:12:58 > 0:13:01or start playing with it when you're getting anxious,
0:13:01 > 0:13:04the smartphone is recording that information and how you've used it.
0:13:04 > 0:13:07As well as measuring what's making the user anxious,
0:13:07 > 0:13:10the app can respond, posting to a social network
0:13:10 > 0:13:12or sending a message to a friend asking for help.
0:13:12 > 0:13:15It can also be set to send a distraction -
0:13:15 > 0:13:18a favourite song or online video,
0:13:18 > 0:13:21to take someone away from whatever's making them so uneasy.
0:13:23 > 0:13:25Every individual with autism is different.
0:13:25 > 0:13:28But for Val, even for a trip to the supermarket
0:13:28 > 0:13:30she needs the company of her support worker.
0:13:30 > 0:13:33Now, which sort of soap? Do you think that one would be good?
0:13:33 > 0:13:37'Technology like this could help her use her phone
0:13:37 > 0:13:39'to gain much more independence.'
0:13:41 > 0:13:44If this technology did come into play and Val was able to use it,
0:13:44 > 0:13:48it would be help her to gain ownership over what she does.
0:13:48 > 0:13:51Rather than having to have me physically there,
0:13:51 > 0:13:54she wouldn't need that, because she'd have prompts on her phone,
0:13:54 > 0:13:56and then if she was to become anxious
0:13:56 > 0:13:59she'd then be able to, you know, use the technology
0:13:59 > 0:14:02and have either a song that she likes come on
0:14:02 > 0:14:04or a shopping list come up on the phone.
0:14:04 > 0:14:08And it might be squeezy balls, or it might be, like I say, a ring,
0:14:08 > 0:14:10- that you could play with.- Yeah.
0:14:10 > 0:14:13'The researchers worked with a small group of people with autism
0:14:13 > 0:14:15'to help them develop their prototype.
0:14:15 > 0:14:18'Later versions could be tailored to different objects
0:14:18 > 0:14:21'or even different fidgeting habits - whatever each individual
0:14:21 > 0:14:24'tends to do with their hands when they become anxious.
0:14:24 > 0:14:26'Val's diagnosis was the first big step
0:14:26 > 0:14:28'to a better and more independent life.
0:14:28 > 0:14:31'Technology like this could give her another tool
0:14:31 > 0:14:35'to help her make sense of a world that can sometimes be frightening.'
0:14:35 > 0:14:39Since I've been diagnosed with autism,
0:14:39 > 0:14:42my life has changed for the better.
0:14:42 > 0:14:45I've learned to cope.
0:14:45 > 0:14:48I've learned to cope with situations.
0:14:48 > 0:14:52I've learned to think for myself.
0:14:54 > 0:14:56Victoria Gill. It's amazing how the best ideas
0:14:56 > 0:14:58are often the simplest, isn't it?
0:14:58 > 0:15:00I have another one here which I'd like to demonstrate to you
0:15:00 > 0:15:02through the medium of pre-packaged ham.
0:15:02 > 0:15:06Now, we're all used to seeing these use-by dates on the packaging, here,
0:15:06 > 0:15:10but this package of ham also has use-by bumps.
0:15:10 > 0:15:12When the meat is still edible,
0:15:12 > 0:15:14this bit up here feels smooth,
0:15:14 > 0:15:17but when it starts to go off, like this one has,
0:15:17 > 0:15:21this starts to feel bumpy.
0:15:21 > 0:15:25Now, this has been entered for the James Dyson design award.
0:15:25 > 0:15:28It's already won an award for inclusive design.
0:15:28 > 0:15:31The inventor is Solveiga Pakstaite. Hi, Solveiga.
0:15:31 > 0:15:35- Hi.- Now, this idea of accessibility and inclusivity
0:15:35 > 0:15:38was the inspiration behind these bumpy labels, wasn't it?
0:15:38 > 0:15:41I realised that blind people don't have any access
0:15:41 > 0:15:44to expiry information on their food.
0:15:44 > 0:15:48So I wanted to create a tactile solution that they could access,
0:15:48 > 0:15:52but because retailers wouldn't find it enough to change something
0:15:52 > 0:15:56just for a minority of people, I needed to add added value,
0:15:56 > 0:15:58so that's when I thought...
0:15:58 > 0:16:00What's another problem that we have?
0:16:00 > 0:16:03It's food waste, and how can I reduce that?
0:16:03 > 0:16:06I've used a natural substance, gelatine,
0:16:06 > 0:16:10er, which when you first set it, it's a solid.
0:16:10 > 0:16:12You set it over these bumps,
0:16:12 > 0:16:15and at first you can't feel the bumps because it's rigid,
0:16:15 > 0:16:18and gelatine, because it's a protein and it's a natural substance,
0:16:18 > 0:16:20it decays at the same rate as the food inside the package,
0:16:20 > 0:16:24and then it has the property of when it expires,
0:16:24 > 0:16:27it turns back into a liquid, which then enables you
0:16:27 > 0:16:29to run your finger over and feel the bumps underneath,
0:16:29 > 0:16:34indicating that the food inside the package is also off.
0:16:34 > 0:16:37Different food goes off at different speeds, so how do these things know
0:16:37 > 0:16:40whether they're attached to something that goes off in two days
0:16:40 > 0:16:43or something that goes off in two weeks?
0:16:43 > 0:16:45You can use the exact same formulation,
0:16:45 > 0:16:48you just need to increase the concentration of the gelatine.
0:16:48 > 0:16:53So the higher it is, the longer the formulation will last.
0:16:53 > 0:16:56So I guess the point is that if there's a printed use-by date,
0:16:56 > 0:16:59that commits to a certain date, that doesn't take into account
0:16:59 > 0:17:02how the food's been stored - whether it's been stored in a fridge
0:17:02 > 0:17:04or in a warm cupboard.
0:17:04 > 0:17:06Absolutely, and that's not the only problem.
0:17:06 > 0:17:10We don't know if retailers are actually being honest
0:17:10 > 0:17:14with the way that they transport and store the food
0:17:14 > 0:17:16before it even hits our fridge.
0:17:16 > 0:17:22For all we know, a lorry could unload a crate of meat
0:17:22 > 0:17:25and it might not go straight into the fridge, as it should,
0:17:25 > 0:17:29and we're trusting this date that says it's still safe to eat,
0:17:29 > 0:17:31when in fact it might not be.
0:17:31 > 0:17:35OK, Solveiga, thank you very much for your time and very best of luck.
0:17:35 > 0:17:37Now, when it comes to labelling our fruit and veg,
0:17:37 > 0:17:40things could be changing already.
0:17:40 > 0:17:42Lara Lewington has been given exclusive access
0:17:42 > 0:17:46to a project which is trialling laser food labelling on fruit,
0:17:46 > 0:17:51which could soon come to around 100 UK branches of Marks & Spencer.
0:17:53 > 0:17:56A grape and citrus packing plant.
0:17:56 > 0:17:59Every year, 1,500 tonnes of fruit are checked, packed
0:17:59 > 0:18:02and given their obligatory labels here
0:18:02 > 0:18:05before being sent on their way to the shops.
0:18:05 > 0:18:09But hidden away at the back is this laser machine
0:18:09 > 0:18:13that could change food labelling as we know it.
0:18:13 > 0:18:17Only a couple of months ago, the EU gave the go-ahead for this technology
0:18:17 > 0:18:21which uses safe iron oxides and hydroxides
0:18:21 > 0:18:23to label fruit and vegetables.
0:18:23 > 0:18:27But now we're there - logos, barcodes, prices,
0:18:27 > 0:18:31use-by dates, and even food traceability information
0:18:31 > 0:18:35could be permanently tattooed on our produce.
0:18:35 > 0:18:39Yes, there have been laser labelling systems around before.
0:18:39 > 0:18:42What the difference between those systems and this system is
0:18:42 > 0:18:46is that this system doesn't damage the fruit in any way whatsoever.
0:18:46 > 0:18:51What it does is remove a tiny amount of pigment from the fruit surface.
0:18:51 > 0:18:53So it doesn't compromise the surface of the fruit
0:18:53 > 0:18:55or the interior in any way at all.
0:18:55 > 0:18:59Or speed up the ageing process.
0:18:59 > 0:19:01Hmm. I don't think I've ever really thought about
0:19:01 > 0:19:03the stickers on oranges before.
0:19:03 > 0:19:07But once you learn that Marks & Spencer in one year alone
0:19:07 > 0:19:11produce seven tonnes of labelling for their oranges,
0:19:11 > 0:19:14you start to see how this could be the future.
0:19:14 > 0:19:17There's a lot of environmental benefits to this, because currently
0:19:17 > 0:19:21paper labels have to be applied to loose products for identification.
0:19:21 > 0:19:23Those labels have to be produced in factories
0:19:23 > 0:19:26and then shipped around the UK and around the world
0:19:26 > 0:19:28to be applied to the products.
0:19:28 > 0:19:31With this technology, it's sent by modem to a machine,
0:19:31 > 0:19:35so there's no stock of labels, designs can be changed easily,
0:19:35 > 0:19:37the carbon footprint is much lower.
0:19:37 > 0:19:39It's a fraction of what it is currently.
0:19:39 > 0:19:42We're going to do the trial first on oranges but we're also looking at
0:19:42 > 0:19:45other products, and one of the products we're excited to look at
0:19:45 > 0:19:46is pumpkins for Halloween.
0:19:46 > 0:19:49Because with pumpkins we can actually etch the image of a face
0:19:49 > 0:19:53on to the side of the fruit to make it easy for customers to cut out
0:19:53 > 0:19:55the shape of the Halloween face.
0:19:55 > 0:20:00So there are options aplenty. But what will the public make of it?
0:20:00 > 0:20:02I think it's better like this.
0:20:02 > 0:20:05It's clear and it's not going to fall off like a sticker would.
0:20:05 > 0:20:08I don't mind that, because that can't come off,
0:20:08 > 0:20:10so I don't mind that at all.
0:20:10 > 0:20:13Personally I think that's a lot clearer. It's an improvement.
0:20:13 > 0:20:15If it was a fruit that you were biting into,
0:20:15 > 0:20:17if you saw that, would you have reservations?
0:20:17 > 0:20:20Well, I wouldn't, but there's possibly people who would have.
0:20:20 > 0:20:22No, I wouldn't like that on an apple.
0:20:22 > 0:20:25And why is that, even if you knew it was safe?
0:20:25 > 0:20:28I think it's just cos it's an apple, I don't know!
0:20:28 > 0:20:31No, I think I would eat it with an apple. I would, yeah.
0:20:31 > 0:20:34You might have two packets of apples in your house.
0:20:34 > 0:20:36'With reactions looking encouraging,
0:20:36 > 0:20:39'this could be a realistic taste of the future.
0:20:39 > 0:20:43'Even if not everyone wants it on their apples.'
0:20:44 > 0:20:47Lara Lewington, lasering fruit.
0:20:47 > 0:20:51Back here at the Science Museum, this is Babbage's Difference Engine.
0:20:51 > 0:20:53It was designed in the late 1840s
0:20:53 > 0:20:57and it's essentially one of the first mechanical calculators.
0:20:57 > 0:20:59This is actually Difference Engine number two.
0:20:59 > 0:21:02If you're wondering what the difference is between two and one,
0:21:02 > 0:21:05apparently it's one.
0:21:05 > 0:21:07Now, I might be getting a little overexcited about this,
0:21:07 > 0:21:10but I'm not alone in that. There's a fair amount of geek blood
0:21:10 > 0:21:14flowing through Kate Russell's veins and she's up next, in Webscape.
0:21:16 > 0:21:19# There's a place and time
0:21:19 > 0:21:22# In the back of my mind... #
0:21:22 > 0:21:24Some dates you always remember,
0:21:24 > 0:21:27like birthdays and hopefully your anniversary.
0:21:27 > 0:21:33But that doesn't make the other 364 days of the year any less special.
0:21:33 > 0:21:37Timehop is a fun free app for iOS and Android
0:21:37 > 0:21:41that reminds you of random things you were doing each day in the past
0:21:41 > 0:21:42by showing you something
0:21:42 > 0:21:45you posted on your social media accounts on that day.
0:21:45 > 0:21:48# There's a place and time... #
0:21:48 > 0:21:51The amount of noise the world makes on social media
0:21:51 > 0:21:55has grown to such an extent it almost defies comprehension.
0:21:55 > 0:21:57Collectively on the web,
0:21:57 > 0:22:00we create as much information in two days now
0:22:00 > 0:22:05as was made from the dawn of civilisation up to 2003.
0:22:05 > 0:22:10So this glance into the past could prove a valuable link
0:22:10 > 0:22:12to those long-forgotten memories.
0:22:14 > 0:22:17You can connect your account with several social channels
0:22:17 > 0:22:20like Facebook, Instagram and Foursquare,
0:22:20 > 0:22:23and then get ready for a daily dose of nostalgia.
0:22:29 > 0:22:33Listening to the chatter online, you might wonder what it all means.
0:22:33 > 0:22:37Test your tech jargon know-how with this quick quiz
0:22:37 > 0:22:40and let us know how you stack up.
0:22:40 > 0:22:43# Get my geek on Get my, get my geek on
0:22:43 > 0:22:46# Get my geek on Get my, get my geek on... #
0:22:46 > 0:22:50It seems there is a neverending supply of quizzes and tests
0:22:50 > 0:22:54to amuse yourself online, from What Computer Am I?
0:22:54 > 0:22:56to What Rodent Are You?
0:22:56 > 0:23:00to Which Hot Dog Represents Your Inner Self?
0:23:00 > 0:23:04If all that seems like a colossal waste of time,
0:23:04 > 0:23:07why not try doing nothing instead?
0:23:09 > 0:23:14To help you, this quirky website asks you to sit and be peaceful
0:23:14 > 0:23:16for two minutes.
0:23:16 > 0:23:18No mouse, no keyboard,
0:23:18 > 0:23:20just sit there.
0:23:20 > 0:23:23The big question is, can you do it?
0:23:28 > 0:23:321:58, 1:59...two minutes!
0:23:32 > 0:23:34Did I miss anything?
0:23:34 > 0:23:37Anyway, that's it from Click at the London Science Museum.
0:23:37 > 0:23:40Hope you enjoyed the programme, and if you'd like to get in touch
