wand and we have another 75 miles an hour and we have another couple of windy days to come across all parts of the british isles to start the week. hello, this is bbc news with shaun ley. the headlines... as tributes continue to pour in for the love island presenter, caroline flack, her management have criticised the crown prosecution service for refusing to drop charges that she assaulted her boyfriend. lewis burton — caroline flack‘s boyfriend — says his "heart is broken". and laura whitmore, who replaced caroline flack as love island host, also paid tribute. at aged 40, caroline flack made

the decision to take her own life, and i want to talk about it. i'm going to talk about her and give her the respect that she deserves and that she didn't always get. heavy rain and strong winds continue to lash large parts of the uk — there are hundreds of flood alerts in place across the uk, including red warnings, meaning there's a danger to life. american citizens quarantined on a cruise ship injapan are to be flown home after a jump in the number of new cases of coronavirus on board. now on bbc news, it's time for click. this week: kitchen hacks go to pot. football scores, and the flippable foldable phone. flat or bended?

last week, youtube revealed for the first time just how much cash it's making parent company google. that was $15,000,000,000 last year. announcing its results for the first time seems like a right of passage — it has grown up and is standing on its own two feet. i visited their london office to find out how it has come of age. kevin, youtube used to be the place where video went viral, but now it seems a lot of that happens on facebook or tiktok. how do you think things have changed? the internet is bigger. it is much easier to make

a beautiful video now than it was ten years ago. when you look at now what the most popular videos on youtube are, they are not viral hit videos, but coming from channels producing lots of content regularly and that have large audiences. i think youtube has moved from this unintentional kind of quick video thing which we all associate with the early years of youtube to this sort of new world in which you have creators who have businesses and build audiences. few could have predicted some of the most successful genres. tell me about asmr. it is short for autonomous sensory meridian response. these are whispered videos, where people whisper or do things quietly to make audiences react. what sort of things might they do? they might whisper, or cook,

or rub things on the microphone. it is a very unusual form of entertainment. but it is not designed necessarily to make you laugh or do the things that we think about for traditional entertainment. it is designed to help you relax or calm down. another big trend is recipes. making something the old—fashioned way can be time—consuming and fiddly. so some of the videos online, particularly many have gone viral, make it look very simple. but is it always possible to do what you are watching? well, chris fox has been finding out. you've probably seen food hacks like these online before — top tricks for tasty treats — but are they too good to be true? millions of videos like this have turned up on youtube and facebook, but do all the tips and recipes work, or will theyjust

waste your time and ingredients? here is a milk carton flan from the lifestyle channel blossom. this video's had 17 million views. you put the ingredients in the carton, microwave it, cool it, and out pops a perfect carton flan. now, i followed this video step—by—step. i've used the exact same quantities. now, the first problem came when i tried to put this in the microwave, because the milk carton was too tall, it wouldn't fit. and that got me thinking, well, how did they fit their milk carton full of ingredients in the microwave? and it looks like they didn't, because if you rewatch the video, you'll see that they actually just cut the bottom of the milk carton off. not to be deterred, i poured the mixture into a gym shaker and followed the rest of the video, putting it in the microwave to boilfor ten minutes. and did i get a flan at the end of it? no, i did not. next up, gummy bear hacks: easy diy dessert recipes for the weekend, recipes from so yummy. 3.2 million views. in this video, melting gummy bears

turns them into jelly. here's me copying what i saw in the video. it turns out gummy bears are actually very thick and gloopy when they are melted, not runny like liquid jelly. will my spoon go into the jelly just as effortlessly as in the so yummy video? well, no it will not. because, as you might expect, this gummy mixture at the bottom of the glass is rock solid. let's have one more. this is from 5—minute crafts. if you've run out of popcorn, why notjust shove an ear of corn in the microwave to make some popcorn? now, i don't need to tell you that if you put an ear of fresh corn into the microwave it will not come out as popcorn but will just be hot corn. but i was willing to be proved wrong, so i tried it out in the name of science. when it comes out, it is warmer than before! i'm not the only one who has been intrigued by this — ann reardon is a food scientist

and runs a cookery channel on youtube, and she's been investigating, too. it's the fake news of the baking work — it's faked baking. the reason why it works is that it's more clickable, and clickbait content is currently working on the youtube algorithm. and apparently working on facebook, too. ann's been trying a lot of these recipes on her youtube channel, too. there's one on so yummy where they make cake icing out of strawberry ice cream. now, ann tried it, and it didn't work. i've also tried it, and it doesn't work. having a food science degree, i know what properties different things have and whether that will work or not. it's not possible to whip up ice cream, because the fat content is not high enough. even if you get the most luxurious ice cream you will get, it will not whip and make frosting. that's an example of the faked ones, but there are now some which are going to dangerous territory as well. one on 5—minute crafts they have one when they put a strawberry in bleach to make it white.

if a child was to watch that and eat it, they could consume a lot of bleach, which is obviously not good for them. there is another video where molten caramel is put over a spinning whisk to make a sort of birds nest decoration to put on top of a dessert. molten caramel is hot — like, it's hotter than boiling water. so we made a box and put plastic wrap in front of it. the hot caramel melted right through it. while we're here, those melted caramel cake decorations they show, that's not the best way to make those, either. it takes a long time to melt one sweet, and usually theyjust burn and stick to the pan. the professional — and just as easy — way, according to ann, is to put your sweets in a blender, put a thin layer of that on greaseproof paper and put it in the oven forjust a few minutes. that's an easy way to make caramel cake decorations that you can try at home. that was chris, and chris is here now. you didn't manage to bring me lunch, though, did you? i should have saved you some of my sweaty egg flan! i'm not sure it looked that appetising! what did the companies have to say? 5—minute crafts, which made

the popcorn video that didn't pop, they didn't reply to my email. and first media, which runs the so yummy and blossom channel, well, they invited me to their studios in la to prove that the recipes work, but they said i couldn't film them doing it. they told me they only put recipes in the videos that do work, although i suspect not as shown in the video because we tried it and they didn't work, and the food scientist, ann, she said some of the recipes, there's no way they would work, even if you followed the instructions and used the most luxurious ingredients. so why are people so busy sharing these videos? i think they are obviously very visual, they are nicely produced. companies would say that the purpose of this is entertainment, they give you cooking ideas and inspiration. and, crucially, most of the people who watch these videos aren't actually going to actually try these recipes, theyjust like the visuals. clearly. and this is what happened when i asked kevin at youtube about this. viewers seem to love these videos

and share them a lot, but they're clearly not actually trying to make the food. i think for a lot of life hack videos, or kitchen hack videos, it's not about trying to take that fact or hack and use it in your life, it's just oddly satisfying to see it play out in front of you. it's just another form of entertainment. does it not matter? is truth that thing of past? truth is not a thing of the past, but i think that there is some contexts in which pure accuracy, perhaps, is not always paramount. keeping up with the pace of technological change can be difficult at the best of times — particularly for parents, who want to be able to keep track of what their children are doing, how much screen time they're having, whether all the content is appropriate. and never has this been more true than when it comes to videogames. so mark cieslak has been looking at this very problem with a spot of help from one of the best—known faces in football. father—of—three and ex—manchester united and england footballer

rio ferdinand is fronting a campaign to encourage parents to learn about the parental controls they can use in their children's videogames. i was someone who's been fairly involved in gaming throughout my adult life, and my children play, and we thought we've had a good balance in our house. you get in, you do your school work, you do your chores about the house, you have a balance between the gaming and being outside. but having an understanding of what your children are actually doing, that's always so invaluable to me to understand what i can actually do in terms of actually controlling what type of games that they're on. do you think parents have to take more responsibility as far as videogames and their children are concerned? you have to take a key interest, like you take a key interest in your child's school life, take an interest in their game life because it's an integral part of their life nowadays like it or not. the get smart about play campaign is the work of the uk games industry trade body. it provides online guides about parental controls on consoles and computers,

controls which can limit play time and prevent children spending real—world money on virtual items. well, we know that more than half of parents in the uk in particular have concerns about the amount of time their children and people in their care are spending playing games and on screens in general. this is part of an overall society digital literacy agenda. you know, so, really understanding boundaries, understanding how to protect yourself, understanding how to protect your privacy, it's part of a wider thing in society that i think we need to really pay attention to. research suggests that up to 99% of children in the uk aged between eight and 15 play video games regularly. compare this to research carried out by the nspcc which found only i9% of parents with children between aged of five and 15 actually use parental controls on devices which connect to the internet. but some parents think that the games industry should bear a greater response ability. are they trying to empower parents,

or are they passing the buck? they have a purpose and a responsibility to actually protect the mental well—being of our children. that is part of their role as i see it. every company that is producing content for our children has to take on that responsibility. features in games like loot boxes, randomised in—game virtual items which can be bought with real—world cash, have been compared to gambling, and have led to increased scrutiny of the industry. so does it need to clean up its act? we are businesses at the end of the day, and these parental controls and family controls are important, because you can turn off in—game spending. that's why the conversation is really important, so it is a shared responsibility. while learning about parental controls improves digital literacy, perhaps some parents who play video games with their children might enjoy the experience as well. hello and welcome to the week in tech.

it was a week that google started its appeal against a £2 billion fine by the european commission. it's alleged the company abused its power by of favouring abused its power by favouring its own shopping comparison service over others. the world's largest mobile show, mobile world congress, has been cancelled over coronavirus concerns. the decision comes after high—profile companies, including nokia, lg, and vodafone pulled out of the event. and speaking of the coronavirus, in times square in new york, a robot has been providing information to curious passers—by about the virus. us and german intelligence services were outed for spying on governments through the control of a swiss encryption firm. from the cold war era up to the 2000s, crypto ag supplied encoding devices which harvested secrets from countries including iran, india and pakistan. the first human clinical controls of a blood—drawing robot have started this week.

researchers at rutgers university found that it performed as well or better than human clinicians. and, finally, some people are heavy—handed, i know i am, but now there's a robotic hand they can do the heavy lifting as well as have a delicate touch. it is capable of handling various objects and tools, like an egg, and playing the piano. it is expected these hands will be used in industrial sites, as well as everyday life. this week saw samsung's unpacked event. yes, it's phone launch time again. here i have the samsung galaxy z flip. now, whether you find this appealing or not, i have to say that on click, we've been to a fair few phone launches and it's quite refreshing to find one that doesn'tjust look like a rectangle. this is samsung's second foldable

phone and is a more compact offering than the first, even though its ultra—thin foldable glass opens up to a 6.7—inch screen. and on the front here you have a display where it can give you all your notifications, when you get phone calls or text messages, they'll pop up there, and there's also a camera so you can take selfies without even opening the device. but once you do open it, well, some apps are optimised to be able to provide you with a viewing zone and an interaction zone. it wasn't long ago that the motorola razr was announced and one of the criticisms that that's received is that the line in the middle where the phone actually folds is a bit too prominent. now, how much that crease would bother me if this was my regular phone, i don't know. i can see a line there but it is a folding phone, so i don't really know what you'd expect. oh, and it would set you back £1,300, by the way.

here i have the samsung galaxy s20 ultra. now, samsung say the main reason that people upgrade their phones is to get a better camera and that's definitely the focus here. in fact, it has up to 100 times zoom. if you take a look behind me, there are two small figurines up there. i'm going to try taking a photograph of them using this device, zooming in and see how clear it's going to be. the camera has io—times optical zoom and beyond that moves into digital zoom. now, once you're in the realms of using the 100 times, the camera engages al to clean up the image as well. ok, it's definitely zoomed in, but the image is very shaky, so i think you'd really struggle to do this holding onto the phone if on a tripod it still looks like this, but you can see more, you can get a clearer image of what you're looking at. the question is — how much use is that photo? you certainly wouldn't want something that looked like that put on your mantelpiece, would you?

this shot has been taken using the a8mp camera and the ai has helped create a clearer shot. let's compare that to this image, which was taken using the 108mp camera, and then after the photo was taken, the picture was zoomed in on. so, that one is sort of clearer in a way. this one looks more like a work of art. over the past few years, rwanda's become a hub for technology in sub—saharan africa. jane copestake has been to look at a unique project hoping to bring electricity to the whole country and possibly avert disaster. lake kivu in rwanda is one of east africa's great lakes. the beautiful landscape is attracting tourists for kayaking and fishing with hopes of generating a lot of revenue for the country, but something even more valuable

is hidden deep within this lake. we're going 14km offshore to see the kiquatt project. it's where they're extracting methane gas from below the surface of the lake. it's the only project like it in the world. this barge took seven years to construct and lies on the lake's border with the democratic republic of the congo. the engineers here work 2a hours a day in 12—hour shifts, monitoring the conditions of the lake. kivu is highly saturated with gases, including methane and carbon dioxide from millions of years of decomposition and volcanic activity. these gases are kept under pressure at significant depths. the lake is 480m deep. however, any disturbance to the lake from seismic activity or a lava flow could result in the gases leaking out. kivu is one of only three known lakes in the world where the specific conditions for this catastrophic event could occur.

they are known as the killer lakes. in1986, a similarlake, lake nyos in cameroon, suffered a carbon dioxide leak. the resulting gas cloud killed over 1,700 people in nearby villages and all other living creatures in its path. if the gases in lake kivu escaped, it could have even more deadly consequences — it's over 1,700 times bigger than lake nyos and over 2 million people live around it. in lake kivu, there's a lot of concentration here, which, of course, is far much more than what we have in lake nyos, so this is why it's very, very important to embark on such projects to reduce the content of the gas on the lakebed. there are 300 billion cubic metres of carbon dioxide and 60 billion cubic metres of methane in the lake. safely extracting the methane will help generate electricity for rwanda, something it desperately needs.

this project is contributing about 30% to the need of the country. 30% — that's impressive. so, that 30% wasn't there before you started? which was not there before, exactly. large pipes below the barge bring in the gas—saturated water. this water is forced into a separator. at a certain depth, the gas starts to separate from the water. the phenomena there is one we would liken to opening a bottle of champagne. when you're allowing the water to be siphoned upwards, then it's also boosted by the lake pressure itself and it's pushing the water upwards. water with a mixture of carbon dioxide, methane and hydrogen sulphide is sent to the barge's wash towers and cleaned. the carbon dioxide and hydrogen sulphide are removed. the de—gassed water is returned to the lake, and methane is delivered by a suspended pipeline to the shore—based power plant for electrical generation.

this is the definition of innovation, building the project right from the design stage up until construction and now into operation. currently, 51% of rwandans have access to electricity. by 2024, the government hopes that will rise to 100%. the kiquatt project plans to deploy three additional barges here to help the country reach this ambitious target. now, over the past few weeks, we've been showing you some of the films nominated in the oscars best visual effects category, but we have saved the best for last, and this week, we have sam mendes‘ epic first world war drama 1917 in store for you. this was the one that took the oscar, and if you haven't seen it yet, what is pretty remarkable is the way that the film is supposed to look like one continuous shot.

general erinmore: your orders are to deliver a message calling off tomorrow morning's attack. if you fail, it will be a massacre. what sam's always wanted to do is to have this idea of the audience being sort of, a part of the story. that, in itself, brings some really difficult challenges. 91% of that film has a visual effect in it, from digital doubles or environment extensions, atmospherics. we put in houses or trees or bushes or canals, and it works at this angle, but then the camera carries on and two minutes later, we're looking at the reverse angle, something like that, and aesthetically it doesn't work, so we had a lot of logistical sort of issues to work out.

what we talked about really was feeling. it's a strange word to use because obviously with visual effects... to help quantify it is we break it down into shots and this gets digitally stitched together, but actually it's more about a feeling of a sequence or a beat. go, go, go! no man's land is a really interesting sequence, because obviously that sort of sets the tone for the journey. this was all shot in england. one of our primary ideas or principles was to make sure that it looked like the north of france. mpc created cg horses, we did environment extensions, fake barbed wire, added a huge amount of craters. sam had this vision for the end scene. 3, 2, 1, go, go! our work is really to tidy up and emphasise what had already

gone on, because a lot of it was all in camera once again, we were only adding a little bit to the story but we weren't dramatically changing anything from battle apart from adding a few more dangerous, sort of, explosions that were closer to our heroes, and obviously the 500 extras who were on the set at that point. we were really adding a little bit more danger and making sure that from a cinematic point of view, it was visually a beautiful scene for them. colonel mackenzie: there is only one way this ends. well, that's it for this week's show. you can keep track of the team throughout the week on instagram, facebook, youtube and twitter — @bbcclick. thanks for watching.

hello, once again. there was much talk in the early part of the day about a red weather warning for the southern parts of wales. i am here to tell you that from 11 o'clock, that warning will have ceased, but you see that we still have other warnings across northern and western britain. these are amber warnings, a slightly lower level of concern from the met office. they run through until 3pm. the one in the south—east keeps on going right through to six o'clock this evening. and that is a completely separate issue, compared to the number of flood warnings. there are still severe flood warnings in both parts of england and wales, and the relevant websites will keep you right up to date. now, just because the rain is showing signs of wanting to pull away from the north of england and from parts of wales during the course of the afternoon, that doesn't mean to say that the flood situation turns off just as quickly.

it by no means doesn't. and this rain is taking its time to slump its way down towards east anglia, the east midlands and into the south—east. so that is why we have that lingering concern with that with that amber warning down at the south—eastern quarter. on what is still going to be a windy day across many parts of the british isles. many of the gusts up to 40, 50, 60 mph. and there will be a cooler, fresher feel to proceedings than has been the case in recent days. through the early part of the evening, the small hours of monday morning, our concern will turn back to the strength of the wind, particularly across the greater part of scotland, the far north of england and northern ireland. here, some of the gusts of wind, as you can see, through the central belt, 60, 70 mph. further north than that, 75, possibly 80 miles an hour. and a real raft of showers as the centre of storm dennis gradually tracks its way past the northern isles on its way to the norwegian coast. should be a frost—free night for many but it will be a chilly start to the new day on monday.

a day not of persistent rain, but there will be some really heavy, squally showers urged along by a noticeable west to south—westerly wind along all parts of the british isles. and there will be that fresher feel. having said that, at least the persistent rain will have disappeared, the rivers will however take a longer time to disgorge their contents out into neighbouring seas. not a great deal of difference on into tuesday. it is wednesday we will begin to see at last a somewhat quieter day across many parts of the british isles. take care, goodbye.

good afternoon. a major incident has been declared in south wales as the strong winds and heavy rain from storm dennis causes flooding and disruption across the uk. there are a record number of flood alerts and flood
