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. i don't want you getting too co mforta ble, show. 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 wa nt to you're ready to take part. do you want to see some tech? crowd: yes! i don't believe you. do you want to see some tech? crowd: yes! i think so. all right. 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 thing, but we're going to put them to one side just for the moment. i'd like to introduce you to the power of your own like to introduce you to the power of yourown mind. like to introduce you to the power of your own mind. breathe slowly and gently, and i'll discover more about you. ..with just gently, and i'll discover more about you. ..withjust a candle. now, gently, and i'll discover more about you. ..withjusta candle. now, i sometimes get some powers and signal 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. . . get pieces of information that come... i'm starting with a "".g let mejust put this come... i'm starting with a "".g let me just put this down for a moment. there's a "g" — 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" i'm getting a "".g let's start with 'g" _ i'm getting a "".g let's start with "g" - gareth? i'm getting a "".g let's start with 'g" - gareth? ithink i'm getting a "".g let's start with 'g" - gareth? i think this is him. 'cause those are two different sites. hello, gareth. how are you? we have joe, and sites. hello, gareth. how are you? we havejoe, and he's sites. hello, gareth. how are you? we have joe, 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 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 — appropriately that i'm dressed like this, because you've lived with a priest, haven't you? laughs have you lived with a priest?|j have, have you lived with a priest?” 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. andrea priest. laughter 0h, right... laughter oh, 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

searching as much as we can about the people that are in front of us. do you have children called jab and sasha? we have cats called jack and sasha. it's close! it's close. i've set upa sasha. it's close! it's close. i've set up a free wi—fi network. most people quite happily click "free wi—fi". people 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. fortu nately, the first thing to work from. fortunately, because it's quite a big event, people have a facebook page. people will say, "i'm at bbc click." we page. people will say, "i'm at bbc click. " we can page. people will say, "i'm at bbc click." we can see that publicly and openly. this is legal. completely legal, yes. that's a question we get asked a lot. we'rejust looking legal, yes. that's a question we get asked a lot. we're just looking at information people have made available themselves? . congratulations on your 4—year anniversary. applause there's two main lessons — be careful what you're signing up for. what's helping us the most right now — people's social media profiles are open and public. we're not saying

not to use it, but 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 see their pictures, their statuses. asa see their pictures, their statuses. as a total stranger, you probably don't want me reading that information. so just don't want me reading that information. sojust — don't want me reading that information. so just — you 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 in your house and small speakers that you wear in your ears oi’ speakers that you wear in your ears or that are built into your smartphones. i'm using 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? we've got a few ultrasound demos here. so i'll tell you what — rather than explain

more about it, shall we, ah, just give it a whirl? 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 unusualfor a you can't hear it again. so this is unusual for a speaker, 'cause 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. 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 a nd wow! this is the weirdest and slowest and most continuous mexican wave i've ever seen... i have no idea what you're hearing, 'cause he's never pointed it in my direction. whoa! seriously? sorry, it's wise unpleasant, isn't it? it can make normal sounds as well. ultrasound is really high—frequency sound, then you're tying other stuff

into that, and sending it around the room? ultrasound is out of the range of human hearing, can is pretty much the definition. we can hear up to 20,000 hetz. anything above that is ultrasound. we can't hear resultened is, but this is an ultrasound wave that's been combined or modulated with a signal. this is notjust the only ultrasound weirdness we've got -it only ultrasound weirdness we've got — it gets even weirder. pop that down, for goodness 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? if we can in here, you can see there's quite a regular pat torn some of these. i can't get too close because it disrupts the sound field. maybe you can see there's a few balls — a bit ofa gap. can see there's a few balls — a bit of a gap. how are you using ultrasound to make stuff levitate? these speakers are producing a big ultrasound signal, that's making a standing wave. in between the gaps of the standing wave, the balls can get trapped and they get kept in the same place. wow! 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, ah, 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. i'm going to try this. my tongue's not long enough... really slowly... laughter 0h! laughter oh! you got it! applause that's really... ..coffee—ee. that's really... ..coffee—ee. 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 it 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 microbit processor orchestra... let's have some more microbits over here in the air. let's have a few at the back... i can see them all in the back... i can see them all in the sky... we are still waiting on the guinness book of world records to get back to us, though. we explored the potentials of ar with our lucky audience members left cowering as a full—scale aircraft suddenly appeared over their heads... hello, world! 300,000 people joined us heads... hello, world! 300,000

peoplejoined us on facebook heads... hello, world! 300,000 people joined us on facebook live during the evening as we asked them whether robots should feel pain. edward nemil, thank you for this question on face bbcback: "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 going to keep having a servant class of robots, then we shouldn't going to keep having a servant class of robots, then we shouldn't go going to keep having a servant class of robots, then we shouldn't go down that route. but the aims are increasing intelligence may make that possible. we watched drones that possible. we watched drones that study the landscape and 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, and 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. course. my name's tom london. i'm a magician, hackerand programmer. you see, 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 anything. to my right here, i've got a nova, an ai anything. to my right here, i've got a nova, an a! machine you can use something called open cv — a library that allows you to create ai, which is hooked up to the cloud through the internet, which allows me to do a large amount ofputing in just 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. 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.

tom. lovely to meet you. i need toical calibrate alexa. in order to do that. i need you to look into the camera and say that for me. alexa, ask your mind to calibrate. alexa: to calibrate, please look into the colour. think of the colour red. think of the colour red. now think of the colour black. 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 canjust 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. all exa, and your mind — "am i thinking of red or black?" your mind — "am i thinking of red or black? " alexa: your mind — "am i thinking of red or black?" alexa: you're thinking of the colour red. can 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. this time, would you like to pick a card? any card you like. 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 little bit closer so i can see you... iwant 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, following — ace, 2, 3, 4, 5, 6, 7. think of the number7, 8, 9, following — ace, 2, 3, 4, 5, 6, 7. think of the number7,8, 9,10, jack, queen, king — calibrated. think of the number7,8, 9,10, jack, queen, king - calibrated. ok, a little bit nervous. it had to do seven a little bit nervous. it had to do seven twice. 0k. can you look into the camera for me and, nice and loud, read out that statement? ok. 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

clu bs. applause 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 our finale... music plays music increases in volume so, um, the psychic career didn't

la st very 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, sol wants a butler, and they can make a lot of money in london, so i thought - "we'll lot of money in london, so i thought — "we'll change, and we'll see if! get more comfortable as a butler." but i've got cards, sol 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 vouve kowlie—kaiter. 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 — we've invited some very special gu ests to — we've invited some very special guests to talk about future food. simmons, bea 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 do 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, viva? they're eating three-d printed raspberries. it's notjust any raspberry — this raspberry has a special recipe. and we print it with this little printer called newfood. we load interesting recipes 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

clea n designed it so it's very easy to clean — it takes very little space on your counter. and you can load any ingredient, and you can —— any kind of liquid ingredient. it can be savoury, kind of liquid ingredient. it can be savoury, it can be sweet, it can be even alcoholic. oh, - that's an even alcoholic. oh, now that's an idea! now, what about the nutritional implications of having three—d—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 all the vitamins and nutrients for yourday ina all the vitamins and nutrients for your day in a very tiny, very tasty flavour bite. so i'm going to try my

own three—d—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. 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. ok. we've got three tie fighters and three x—wings? drones? yes. ok. 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't just toys of star wars drones. these drones aren'tjust toys — they of star wars drones. these drones aren't just 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 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 99% accurate to flying a drone in the realworld. the barometric pressure keeps it a specific height. and they also do one other fun 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... feeling? nervous. like, really nervous. ifeel... ..i don't feeling? nervous. like, really nervous. i feel... ..i don't know, i'mjust nervous. i feel... ..i don't know, i'm just nervous. nervous. i feel... ..i don't know, i'mjust nervous. how's 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, 2and4 automatically turn and go. drones i, 2 and 4 all with the same amount of

points right now. it is all to play the imperial pilots are doing awfully right now. the rebel pilots are doing well, and now shooting against one another. still piloti 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 ititant 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. following what has been a pretty stormy start to 2018, the weekend holds something a little quieter for the most of us, but colder, and it will feel cold as well as the wind, northeasterly wind, strengthens. and of course it is getting colder, so what we have seen through the day on friday is a smattering of snow on the hills. those weather fronts have continued southwards through the night so a further smattering of snow and clearly an ice risk across many northern areas. but even further south, as temrperatures fall close to freezing as well for dawn this morning, and some showers around, that poses a risk of fog as well, some dense fog, potentially through parts of southern areas but particularly across parts of wales, the midlands, east anglia,

lincolnshire and the vale of york but not to be excluded further south either where we will keep a lot of showers through the day ahead and quite cloudy skies. as the wind starts to strengthen, it will be quite bitter. the wind is a feature further north but the list with the sunshine here it will be a sparkling start of the day. it will still be cold. wintry showers are still there across parts of north—east england, in scotland but for western scotland, northern ireland, the lion's share of the sunshine through the day ahead but it does brighten and across much of northern england, north wales, perhaps the north midlands later and the fog will lift. before that, the wind strengthens and with the cloud covering the south and the showers, quite sharp at times, it will feel cold, for example if you are heading off to fleetwood against leicester in london for the fa cup third round, it will be quite a bracing wind, particularly by the end of play. for most of us here, 6—8 celsius but feeling colder as the wind strengthens. the wind starts to ease and the sunshine further north but again 3—5 degrees, it is cold air. that cold air continues its progress southwards

during tonight, still though we have the cloud generally, showers close to the south coast, touch and go for frost but most areas will have a much colder night. —io, —12 in the glens of scotland, particularly with the snow cover, but colder further south and a risk that of some slippery whether we have had the showers. it looks like a sunny day on sunday but look at the north—easterly wind. it is biting. always the risk of a bit more cloud for the south but lovely sunshine further north, just cold, temperatures, was struggling to get above freezing in a few areas because of the high pressure, light winds in the north, the strong north—easterly is in the south and these were the front sitting out in the atlantic which will slowly start to come in next week but another day of largely dry weather, just picking up some cloud and freezing drizzle by monday. it looks more grey by that stage. to get up—to—date, there is more of course on our website. bye— bye. welcome to bbc news, broadcasting to viewers in north america on pbs and around the globe. i'm duncan golestani.

our top stories: the united states is criticised by fellow un security council members for calling an emergency meeting over protests in iran. the author of a damning book on donald trump says he stands by everything he wrote in his depiction of a chaotic white house. i will tell you the one description that everyone gave, everyone has in common they all say he is like a child. at least 19 people have died, and temperatures could fall to minus 40 in some places this weekend.
