Now on bbc news, formerfootballer Rio Ferdinand is on a mission to educate parents about the gaming habits of their children, in 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 its 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 the service has matured, grown up and is standing on its own to feed. 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. Quietly to make audiences feel relaxed. Whispering 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. Youve probably been seeing 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 the 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 videos 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. Ive 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 wouldnt 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 didnt, because if you rewatch the video, youll see that they actually just cut the bottom of the milk carton off. Not to be deterred, i put 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. Heres 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. Lets have one more. This is from 5 minute crafts. If youve run out of popcorn, why notjust shove an ear of corn in the microwave to make some popcorn . Now, i dont 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 im not the only one who has been intrigued by this ann reardon is a food scientist and runs a cookery channel on youtube, and shes been investigating, too. Its the fake news of the cooking work its faked baking. The reason why it works is that its more clickable, and clickbait content is currently working on the youtube algorithm. And apparently working on facebook, too. Anns been trying a lot of these recipes on her youtube channel, too. Theres one on so yummy where they make cake icing out of strawberry ice cream. Now, ann tried it, and it didnt work. Ive also tried it, and it doesnt work. Having a food science degree, i know what properties Different Things have and whether that will work or not. Its 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. Thats 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 do 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, its 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 were here, those melted caramel cake decorations they show, thats 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. Thats an easy way to make caramel cake decorations that you can try at home. That was chris, and chris is here now. You didnt manage to bring me lunch, though, did you . I should have saved you some of my sweaty egg flan im not sure it looked that appetising what did the companies have to say . 5 minute crafts, which made the popcorn video that didnt pop, they didnt 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 couldnt 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 didnt work, and the food scientist, ann, she said some of the recipes, theres 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 arent 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 theyre clearly not actually trying to make the food. I think for a lot of life hack videos, or kitchen hack videos, its not about trying to take that fact or hack and use it in your life, its just oddly satisfying to see it play out in front of you. Its 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 theyre having, whether all the content is appropriate. And never has this been more true than when it comes to video games. 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 childrens video games. I was someone whos been fairly involved in gaming throughout my adult life, and my children play, and we thought weve 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, thats always so invaluable to me to understand what i can actually do in terms of actually controlling what type of games that theyre on. Do you think parents have to take more responsibility as far as video games and their children are concerned . You have to take a key interest, like you take a key interest in your Childs School life, take an interest in their game life because its 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 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, its 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. A greater responsibility. 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 are important, because you can turn of in game spending. Thats 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. Its alleged the company abused its power by of favouring its own shopping Comparison Service over others. The Worlds 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 20005, 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 theres 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 samsungs unpacked event. Yes, its a 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, weve been to a fair few phone launches and its quite refreshing to find one that doesntjust look like a rectangle. This is samsungs 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, theyll pop up there and theres 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 wasnt long ago that the motorola razr was announced and one of the criticisms that thats 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 dont know. I can see a line there but it is a folding phone, so i dont really know what youd 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 people upgrade their phones is to get a better camera and thats 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. Im going to try taking a photograph of them using this device, zooming in and seeing how clear its going to be. The camera has io times optical zoom and beyond that moves into digital zoom. Now, once youre in the realms of using the 100 times, the camera engages al to clean up the image as well. Ok, its definitely zoomed in but the image is very shaky, so i think youd 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 youre looking. The question is how much use is that photo . You certainly wouldnt want something that looked like that on your mantelpiece, would you . This shot has been taken using the a8mp camera and the a has helped make a clear shot. Lets compare that to this image taken using the 108mp camera and then after the photo was taken the picture was zoomed in on. That one is sort of clear in a way. This one looks more like a work of art. Over the past few years, rwandas 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 africas 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. Were going iakm offshore to see the kiquatt project, its where theyre extracting methane gas from below the surface of the lake. Its the only project like it in the world. This barge took seven years to construct and lies on the lakes 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. Ini986, 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 its over 1,700 times bigger than lake nyos and over 2 Million People live around it. In lake kivu, theres a lot of concentration here, which, of course, is far more than what we have in lake nyos, so this is why its very important to embark on such a project 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 , thats impressive. So that 30 wasnt 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 youre allowing the water to be siphoned upwards, then its also boosted by the lake pressure itself and its pushing the water upwards. Water with a mixture of Carbon Dioxide, methane and Hydrogen Sulphide is sent to the barges 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, weve 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 havent 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 mornings attack. If you fail, it will be a massacre. What sams always wanted to do is to have the idea that the audience be in, sort of, a part of the story. Instead of being in a window to the world of something, it gives the idea that the audience is travelling and going along with the story as an extra character, should we say. That in itself brings in 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, and the camera carries on and two minutes later, were looking at the reverse angle, Something Like that, and aesthetically it doesnt work, so we had a lot of logistical, sort of, issues to work out. What we talked about really was feeling. Its 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 its more about a feeling of a sequence or a beat. Go, go, go no mans land is a really interesting sequence, because obviously that 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 seen. Three, two, one, 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, sam had this vision for the end scene. Three, two, one, 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 werent 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. Dramatic engine noise well, thats it for this weeks show. Well, thats it for this weeks show. You can keep track of the team throughout the week on instagram, facebook, youtube and twitter bbcclick. Thanks for watching. Storm dennis is arriving. The winds have been picking up, the rain has been moving in as well and we will find reverent levels rising too.
