hello, welcome. welcome, how are you? hello... 7 welcome, welcome... second script — "how are you? how are you?" hello, everybody! i am literally being built from the skin out, currently, by these two lovely ladies who are going to try to make me look like my publicity photograph. all right, then. we are all good to go, brendan, you happy? so what we're going to do is go to silence, please, and go to black. lose the house lights. vt10 next. announcer: this is bbc click live.

please welcome your host, spencer kelly! cheering and applause erm...right! there. hello! welcome. my own floor! welcome to click live, and have we got a show for you! have we got a show for them? we have, we're ready to go. laughter we have some really amazing things for you tonight. we've got some things that noise, we've got some things that fly, we have some things for you to taste. some of it won't work, 0k? laughter bear with us, because hopefully the stuff that does work — fingers crossed, and a lot of it has in rehearsals — it is a world—first, and you won't see this anywhere else, and no—one has seen this before you. before any of that, i have to introduce you to the other half of the show. please welcome to the stage kate russell. applause

brilliant, isn't it? when they said i'd have my name in lights, i was expecting more broadway than boardwalk — but it's a start! it's going to be a really, really crammed show. and i don't want you getting too comfortable, because there's a lot of audience participation. so i hope you're ready to take part. do you want to see some tech? crowd: yes! good stuff. i don't believe you. do you want to see some tech? crowd: yes! i think so. all right, so first of all, we need you to settle down, because our first guest tonight is very mysterious. his name is psychicjoe, and i'm told things are about to get very strange... eerie music playing hello. computers are a wonderful thing, but we're going to put them to one sidejust for the moment.

i'd like to introduce you to the power of your own mind. breathe slowly and gently, and i'll discover more about you, with just a candle. now, i sometimes get some powers and signals through, and sometimes i get things wrong. but most of the time, it's right. so stay with me. i mightjust get pieces of information that come... i'm starting with a "".g let me just put this down for a moment. there's a "g" — so i'm going to start to pull something out of the audience. hopefully it's one of you. i'm getting a "".g let's start with "g" — gareth? i think this is him. because those are two different sites. hello, gareth. how are you? we havejoe, and he's going to identify some people in the audience, and he's going to pretend to read their mind by telling them things about them, by reading information from them. it's actually us researching these

people online and feeding that to him through a hidden earpiece. les? les...? it could have been a man, but i won't make wild assertions. is there a les? leslie? welcome to the show. glad you've got a microphone with you now. what can i tell you about yourself? um, you have — appropriate that i'm dressed like this, because you've lived with a priest, haven't you? laughs have you lived with a priest? i have, yes. you've actually lived with a priest? she's right here. you don't look like a priest at all, do you? what's your name? andrea priest. laughter 0h, right... so we're researching some of the people in the audience right now. the gentleman who's just sat down in front of us — i've just found the address details of somebody who sat down at the front with her partner as well. so we're researching as much as we can about the people that are in front of us. do you have children called jack and sasha? um. . .we have cats called jack and sasha.

oh, it's close! it's close, isn't it? i've set up a free wi—fi network. most people quite happily click "free wi—fi". it says please type in their name, click "connect", and that is how we start. we then have their name. it's the first thing to work from. fortunately, as well, because it's quite a big event, people will like the facebook page. people will say, "i'm at bbc click." we can see that publicly and openly. is this legal? completely legal, yes. that's a question we get asked a lot. we're just looking at information people have made available themselves. but congratulations on your four—year anniversary. a round of applause please. applause there's two main lessons - be careful what you're signing up for. the biggest thing that's helping us the most right now — people's social media profiles are open and public. we're not saying not to use it, just check that your profile is private. i'm a complete stranger to everybody in this audience, but so far i've been able to go onto all of their profiles and look at where they were born, their pictures, their statuses.

as a total stranger, you probably don't want me reading that information. so just — we're not saying don't use it — just make it private so only your friends can see. that would protect you from all of the things we've found out so far, actually. we listen to radio, to tv, to music, to podcasts, using speakers. big speakers in your house and small speakers that you wear in your ears or that are built into your smartphones. so i'm just choosing the perfect bit of coffee for the levitation. it has to be both kind of small, but also regular, and i don't think they normally make coffee beans with levitation in mind. one of the things that steve has been working on is ultrasounds, 0k? and we've got a few ultrasound demos here. so i'll tell you what — rather than explain more about it, shall we, uh...just give it a whirl? so i'll tell you what — who's getting something there? raise your hand if you can hear this, then drop your hand as soon as you can't hear it again.

so this is unusual for a speaker, because usually when you switch a speaker on, everyone can hear it. right now, we're getting a really narrow beam. really focused beam of sound. so if you imagine this is a lot like a flashlight, imagine i'm pointing a torch around the room. you'd only see certain parts of it. this is the same idea, except with sound. so we're focusing the sound and we can focus all that energy, all that sound energy, in a specific place. wow! this is the weirdest and slowest and most continuous mexican wave i've ever seen... i have no idea what you're hearing, because he's never pointed it in my direction. beeping whoa! seriously? sorry, it's quite unpleasant, isn't it? it can make normal sounds as well. so ultrasound is really high—frequency sound, and then you're tying other stuff into that, which you're then sending around the room? so ultrasound is out of the range of human hearing, is pretty much the definition. we can hear up to 20,000 hertz, and anything

above that is ultrasound. we can't hear ultrasound, but this is an ultrasound wave that's been combined or modulated with an audible signal. i tell you what — this is not just the only ultrasound weirdness we've got. it gets even weirder. pop that down, for goodness‘s sake. this looks like it's landed from another planet. this is incredible. stephen, for the second time tonight, what on earth is going on? so, if we can in here, you can see there's quite a regular pattern on some of these. i can't get too close because it disrupts the sound field. but maybe you can see there's a few balls — a bit of a gap. so how are you using ultrasound to actually make stuff levitate? well, these speakers are producing a big ultrasound signal, that's making a standing wave. and in between the gaps of the standing wave, the balls can get trapped and they get kept in the same place. oh, wow!

well, that's fantastic. in fact, that's so amazing, steve, i think we deserve a drink. would you mix us one? yes, of course, spencer. fantastic, right. this is the weirdest drink... we rehearsed that, could you tell? what is this, steve? we've got a lovely, lovely delight for you today. it's a single grain of coffee with a, uh...drop of milk, all levitating in the middle of the air. it's a latte. laughter you have to have it in, though. you can't have it to go, unfortunately. right, so i'm going to try this. my tongue's not long enough... really slowly... laughter 0h! you got it! applause that's really...coffee—y. that's like really, really strong. is that supposed to be that strong? yes, yeah. that's what we've found. sugar tastes sweeter, and coffee's bitter. fantastic. sri, steve, thank you very much.

a round of applause for sri, steve and the ultrasound latte! applause there were so many amazing demos and displays in the show that we just can't fit into this program. here's a look at some of the other highlights from our evening of delight. we transformed our tech—loving audience into musicians, as kate and i conducted the biggest ever micro:bit processor orchestra. let's have some more micro:bits over here in the air. ok, let's have a few at the back. hold those up. 0h, great. i can see them all in the sky. we are still waiting on the guinness book of records to get back to us, though. we explored the potential of ar, with our lucky audience members left cowering as a full—scale aircraft suddenly appeared over their heads. hello, world! 300,000 peoplejoined us on facebook live during the evening as we asked them whether robots should feel pain. edward nemil, thank you for this question on facebook: "sacrificing a robot for the greater

good might be necessary. why would you want it to feel pain?" if we're going to keep having a servant class of robots, then we shouldn't go down that route. but the aims of increasing intelligence may make that impossible. we watched drones that study the landscape and drones that dive, as we looked at how they could help in the future. hello, everybody. i'm an environmental scientist. i'm interested in how landscapes, in particularly plants, function. we use what we call remote—sensing techniques — we fit cameras to drones and aircraft, and even use satellites, to monitor the health of ecosystems. we use thermal imaging on these drones to monitor the status of the hydrological status of ecosystems. and it's not a click live without a little bit of magic — using artificial intelligence, of course. my name's tom london.

i'm a magician, hacker and programmer. with technology, machines can think a thousand times faster than we can. and, because of this, i've worked out a way how to accomplish a thing i've wanted more than anything. to my right here, i've got a creoqode nova, an a! machine you can purchase and learn to build ai using something called 0pencv — an open—source library that allows you to create ai. that's hooked up to the cloud through the internet, which allows me to use multiple instances of service to do a large amount of computing injust a second. 0n the other end, i've got an alexa, which i'm sure you're all familiar with. i'll try and see if we can get it to read someone's mind. who would like to have their mind read? immediately, this gentleman over here is like, "yes, i definitely want to have my mind read." do you want to give this gentleman a round of applause as he comes onto the stage? applause hi, there. what's your name? mark. mark, tom. lovely to meet you. i need to calibrate alexa.

in order to do that, i want you to look into the camera and say that for me. alexa, ask your mind to calibrate colour. alexa: to calibrate, please look into the camera. think of the colour red. now think of the colour black. think of the colour black. calibration complete. fantastic. the calibration is now completed. hopefully what should happen now is you should be able to get this right. to make this more visual, i've got a pack of cards over there. can you grab those for me? 0pen them up. never before does the magician ever give the cards away to a spectator. it's kind of rule one in the magic world. because i'm not doing any magic today, i have no problem with doing this. do you want to take them out, give them a little shuffle? yeah, you can leave them over there. i don't want to see it. they're all normal, just playing cards. i wanted to have a really visual aid of the colour you're thinking of. pick a card, put the rest of the cards down, then head over to my ai.

fantastic. if you can just stand over here and, once again, look at the camera. fantastic. i want you to read this out for me, nice and loud. we'll see if we can get this to work. ready? go for it. alexa, ask your mind — "am i thinking of red or black?" alexa: you're thinking of the colour red. can you please show the card to the camera over there? ladies and gentlemen, it is, in fact, the colour red. applause because i have all this computing power at my hand, we can actually try something a lot more daring. would you like to pick a card? any card you like. it's up to you. same thing again. and you can — yeah, go for it... before we do this, just stand in front of the camera and — just a little bit closer so i can see you... i want you to read this out nice and loud. alexa, ask your mind to calibrate playing cards. alexa: to calibrate,

please look into the camera. think of the following — ace, 2, 3, 4, 5, 6, 7... think of the number 7, 8, 9, 10, jack, queen, king. calibrated. 0k, a little bit nervous. it had to do 7 twice. can you look into the camera for me and, nice and loud, read out that statement? alexa, ask your mind — "what card am i thinking of?" alexa: i'm not quite sure how to help you with that. laughter alexa, ask your mind — "what card is he thinking of?" alexa: you're thinking of the 6 of clubs. mark, please show the card to the camera. it is, in fact, the 6 of clubs. can we have a massive round of applause, please, for mark? thank you so much. i'll take those. take a seat.

did anyone try the drones in the media cafe before you came in? anyone have a go at flying those drones? if you've earnt your wings and you were given a gold badge with wings on it, i'd like you to come to the front. you've got a chance of winning, later on in the show, and be part of ourfinale... music plays so, um, the psychic career didn't last very long? not very long, no. i made a few mistakes. i thought i'd change it for something more profitable.

kate's decided that she wants a butler, and they can make a lot of money in london, so i thought — "we'll change, and we'll see if i can get more comfortable as a butler." but i've got cards, so i know who i'm talking to this time. they're definitely going to be at the table. doorbell rings piano playing announcing ms kate russell and dr vaiva kalnikaite. applause thank you, simmons. do take a seat, viva. we have set a very special table here in the click live studio — we've invited some very special guests to talk about future food. simmons, be a good chap and deliver some simple morsels to the audience. now, we are delivering to you some raspberries to taste. please, if you have food allergies, do not taste them — they may not necessarily

be raspberries. if you have no food allergies, please help yourself to a sumptuous fruit and see what you think. you're doing a terribly good job there, simmons. now, quick — just a nod. do you like it? is it tasty? so, what are they eating, vaiva? they're eating 3d—printed raspberries. it's notjust any raspberry — this raspberry has a special recipe. and we print it with this little printer called nufood. we load an interesting recipe that have interesting ingredients — for example, raspberry — and we design a shape on an app, and when we press "play"... let's start building a raspberry! this is the kind of device that one could, in the future, expect to have in one's kitchen, perhaps? exactly. we've designed it so it's very easy to clean — it takes very little

space on your counter. and you can load any ingredient, any kind of liquid ingredient. it can be savoury, it can be sweet, it can be even alcoholic. oh, now that's an idea! now, what about the nutritional implications of having 3d—printed food capabilities in the kitchen at home? i mean, could we help solve the nation's obesity crisis, for example? brussel sprouts — who likes brussel sprouts? i mean, i do. but if you can make brussel sprouts taste like chocolate cake, surely that's going to be a good thing, right? exactly. you can make things taste really delicious with the flavours you like, but you can also tailor nutrition to make sure that you have all the right vitamins and nutrients in every single bite. so imagine having breakfast where you just take a superberry that has all the vitamins and nutrients for your day in a very tiny, very tasty flavour bite.

so i'm going to try my own 3d—printed raspberry... mm! oh, gosh. it's quite hot. it's given me sucking—cheeks effect. that's brilliant, and absolutely fascinating that it literally built it here on its own. i'd like to introduce you to our head pilot for the evening. this is jack bishop. jack, welcome. thank you. ok, so, can you... ..we're going to fill the drone cage in a second with six star wars—themed drones? yes. 0k. we've got three tie fighters and three x—wings? correct. can you explain why we're showing these drones, why they're easy to fly and fun to watch? sure.

we're from propel, and we've created a set of star wars drones. these drones aren'tjust toys — they actually have some of the latest and greatest technology that's available to us today. they're super, super easy to fly with the help of a barometric air—pressure sensor, which knows how high the drone is, and maintains that height. we've also built an app that teaches you — if you're a brand new drone pilot that's never flown before — from a complete beginner to an advanced drone battle pilot. that's without using the drone, so you don't crash it? correct. we use a bluetooth connection to your android or apple device. there's virtually zero latency — it's 98%, 99% accurate to flying a drone in the real world. the barometric pressure keeps it a specific height. and they also do one otherfun thing...? they fire lasers. they fire laser beams! that's what we're going to do now. to demonstrate this... how are you feeling? nervous. like, really nervous. i feel... ..i don't know, i'm just nervous. how's your pilot training going? it's good. excited? yeah. we've got our six specially trained — and they now have been trained in the five minutes since they've left —

specially trained pilots to have a battle to the death. the pilots are ready. without any further ado, let's get this battle started...! music plays these guys have taken off, and they're firing their lasers... these guys are actually scoring points against one another. currently, we have piloti in the lead with two points, and pilot 2 also with two points... remember to keep your drone facing away from you. so these guys are all shooting at each other. when you see a drone shake in the air like this, that means that it's been hit — it loses a life. after you lose all three lives, your drone will automatically turn and go. drones i, 2 and 4 all with the same amount of points right now. it is all to play for! the imperial pilots are doing awfully right now. the rebel pilots are doing well, and now shooting against one another. still pilot! and pilot

2 in the lead so far. we've got one still in the air, which means our winner is a rebel pilot! cheering and applause congratulations for that, rebel pilot — staying in the air for the most amount of time. you are the winner! i think nearly everything worked, as well, but that is it for tonight. i've had a ball. have you had a ball? it's been absolutely amazing. have you had a good time? crowd: yes! thank you very much for watching, and we will see you soon. bye. cheering and applause cut it. well done, well done, well done. hello there.

sunday is set to be another very cold day. we have clear skies which is set to bring us a good deal of sunshine by day, but dawn could well look something like this. a lot of sharp frost around, the potential for temperatures close to —15 degrees across the sheltered glens of scotland. so a very cold start with some icy stretches to watch out for as well. a lot of sunshine on offer, though, as we move through the day on sunday. let's look at the morning. it's across the rural glens of scotland that we will have the coldest temperatures, as i say, potentially close to —15. around about —8 eight by 9am. a few showers for the northern isles of scotland. down across northern ireland and northern england,

lots of sparkling sunshine, frosty — watch out for some icy stretches, particularly where we have had some showers. there could still be a few showers across the north—east of england. a lot of dry, sunny weather towards the south—east. just a little bit of cloud drifting around. bit of wind chill with the brisk north—easterly winds across southern england and wales, too. but through the day, it is looking dry, fine and settled after that cold, frosty and icy morning. there will be a lot of sunshine on offer for most places. quite breezy, i think, in the far south, and also for the northern isles of scotland with one or two showers. elsewhere, dry, but temperatures only between around about zero to six degrees for most of us. sunday also ending on a cold note. another very cold night ahead sunday night and on into monday morning. if you're heading to work during the early hours of monday, do watch out for some icy stretches forming once again on the roads because even in towns and cities, the temperatures will be down below freezing. just a little milder along the south coast because we will have a bit more cloud filtering in here through monday morning. and that's going to be a theme for monday.

the cloud in the south will nudge its way further northwards, so clouding over, i think, for parts of east anglia, the midlands into wales later on in the day. it will still cold where you have the cloud around, too. lots of sunshine and northern england, scotland and northern ireland, too. fairly light winds across much of the country. another largely dry day, 2—6, but that cloud just thick enough potentially for a little bit of drizzle along the south coast. and then eventually, we lose the blue colours, the cold air mass, and we'll see something a little milder creeping in from the atlantic as we head through monday night and into tuesday, too, with eventually some wet weather arriving in the west. but actually, much of tuesday again dry, fairly cold, fairly cloudy, the breeze picking up from the west. that is ahead of this band of rain which will bring milder but also wetter weather from the west as we head through the end of the day. temperatures around 4—6 degrees on tuesday. slowly turning a little bit milder with some outbreaks of rain through the course of next week. goodbye. this is bbc news, i'm duncan golestani. our top stories: in the next few
