tariffs on turkey, amid worsening relations between the two countries. it adds further pressure to turkey's economy, the lira falling to an all—time low after the announcement, losing 20% of its value in 2a hours. the saudi—led coalition has announced it will investigate its air strike in yemen which killed at least 29 children. the attack targeted a school bus in the town of saada which is under the control of iranian—backed houthi rebels. the un says investigations must be credible and transparent. tens of thousands of romanians have been protesting in the capital city over corruption and low wages. police used tear gas and water cannon to disperse crowds. now on bbc news, click. this week, it's a summer sizzler

with wheels. slides. and a very scary chicken. the sun is shining, the temperature is soaring. the science says we are going to have more and more of this weather in the future and fortu nately, weather in the future and fortunately, the uk heatwave is less

punishing than many places so we have done that british thing of dressing inappropriately in letting the robots do the work. they do know this is astroturf? i'm afraid the heat has finally got to us we are cracking open the summer gadgets, and my legs, sorry about those. first, fire up the barbie and forget coal, forget gas, this is the gosun go which focuses the heat on to a tube where the temperature can get up tube where the temperature can get up to 280. you can fill it with water if you fancy tea on the go. we have loaded it with lunch so we will see how it is going a bit later. and while we wait to say —— to see whether the beefsteak browns, stephen beckett has been cooling off the only way that he knows how.

welcome to erding, one of the largest thermal baths in europe, the best place to relax, have a drink, do some pool yoga. and did i mention, there are also 27 waterslides. there is a water slide, there is another one, that is a water slide. yes, this is also europe's biggest waterslide park. but with 4500 europe's biggest waterslide park. but with a500 people visiting the everyday, is 27 slides enough? what if you could change the slide at the click of a switch? it's time to get my trunks on for some serious journalism. to go of the newest rides in the park, i will need more than my togs and a tube, i will need one of these. it was actually amazing. i was a bit

sceptical. i needed a bit of practice, i was going backwards and forwards and didn't feel in control, i went down that slide with my eyes shut. i am i went down that slide with my eyes shut. iam no i went down that slide with my eyes shut. i am no slide, i went down that slide with my eyes shut. iam no slide, server i went down that slide with my eyes shut. i am no slide, server that was good. because it's a br slide, how about sliding through the snowy mountains, outer space, the alien planet. for virtual slides packed into the twists and turns of one real slide. you make some slides, i like it, more without glasses because they are overloaded with the system but the young people, the kids in the young people and families we have here, about 10— 29, they like it and love it and they say it's the best thing they ever did in their laughs and now we get

about more than 50,000 visitors. normal bland blubbing vr headsets have already got a bit of a rap about being compared to use sick getting the aquatic version to work well has been a challenge. it was very difficult, the first thing we have to convince the owner that we wa nt to have to convince the owner that we want to do it. and then the owner tried it and after two tries, he was sick and he said, no, i don't like this, i don't want. the difficulties if you go on the slide in the left side we gone the right side, you get this motion sickness. and to see how to solve that problem, first we need to solve that problem, first we need to get rid of some of this water. all along this slide of these sensors and that so the virtual reality headset knows where you are at exactly the right time because you want what you are seen to be the

same as what to appealing. get it wrong and you could end up feeling a little bit sick. stephen greenwood and his team spent months building and his team spent months building and crucially testing the system. we did hundreds of tests going down the slide, each one of us has ridden the slide, each one of us has ridden the slide hundreds of times because we had to make sure that we got it right. stephen's next plan is to ta ke right. stephen's next plan is to take the vr offers slides and into the wild. this is a diving mask version. you got a virtual reality headset. the idea of this is that people need to practise diving, repairers and astronauts, can train in one of these but i'm just going to go on the shipwreck. when you combine that sensory feeling of being a different and brian meant and that virtual world of the rise, it's a powerful combination. there

isa it's a powerful combination. there is a huge potentialfor military it's a powerful combination. there is a huge potential for military and marine technician training. these prototypes still need some work. for me, the image was imperfect and more importantly, the waterproof phone thatis importantly, the waterproof phone that is hidden inside only knows where you are looking, not where you're moving. solving that problem is the next big challenge and in terms of the slide, they have plans for that too. we are considering more features like sound and other sensory elements. there is a big therapeutic factor, there is a lot we can do with physical therapy, meditation, rehabilitations, and some of the psychological benefits you can have from floating in water and having a relaxing experience in front of your eyes. it sounds like this could be the start of aquatic vr. right now, ijust will do the testing. that seemed like a really tough assignment. it is hard, it was difficult, i did it for you guys.

you've done a lot of work with br over the last two or three years and it seems we are talking more about vr coming to these theme park areas. the thing is, headsets are still quite expensive, they are getting cheaper but they are quite expensive and are difficult to use selena themepark environment, it can be controlled and managed and this is the thing, not everyone has a rollercoaster or a waterslide in our home. that's true. it does seem that adds to the experience, it adds to the sense is because vr doesn't do that. the promise of a br that we see in sci—fi films is that vr will totally immerse us but at the moment, vr only full is to sensors, oui’ moment, vr only full is to sensors, our rise and arias, and it doesn't do that particularly well so maybe this is the first step of the sense of motion, the sense of touch. did you enjoy it, stupid question?” enjoyed it. i had reservations about going down the slide with my eyes

closed but once you do that, it's fun, it's good. well done, take a long deserved break, it was arduous. it is hard. we've been in the water in time to go for a bike ride. gone are the days and you could slap on a cycling helmet, these days you have to load up with the latest cycling tech. it's the law and that is what la ra tech. it's the law and that is what lara has been doing with the help of click‘s own boss, simon. meet simon. a regular cyclist and the editor of click. -- a regular cyclist and the editor of click. —— click mac. first off is the smart cycle helmet connecting via bluetooth and you can hear any sound from your phone that can be directions or music without blocking out the sound of the road around you. be safe. thank you. it can be controlled via a remote or its app

which allows you to save routes and share data with friends. it also has a wind resistant microphone designed for calls if you consider chatting on the phone while cycling is a good idea, that is. we had a nice chat on the phone there, the sound was amazing. probably the best thing i tried on a bike like that. with this you got the added i mention of making sure the bone conduction things are on the right place. getting jawbone writers always a difficult and with this, really after a couple of weeks of trying to perfect it to get the perfect signal, the kind of have to get it so tight you are almost garrotting yourself. when you are in the middle of london and there is loads of traffic, it's kind of difficult to hear, i suppose, some people would say, it's better to hear the traffic than the music anyway. this is

r-pur, than the music anyway. this is r—pur, and antipollution mask the cyclists and non— cyclists, which claimed to keep pollution, pollen and viruses and bacteria at bay and based on where you've been cycling, the apple axis pollution data at the ground and you need to replace the filter. you looks slightly menacing in that. it's also 30 degrees london today. it's pretty harsh. it's better than some i have tried. it's a lot more comfortable than some i've tried before and it's a slightly nicer design perhaps. that said, is very expensive compared to other masks. how about the idea that it connects to an end aims to track the pollution you are going to be encountering? to me, that sounds like a bit of tech overdesigned. you can use commonsense of the bit to know when to change filters. finally, we have blinkers which are

claimed to be the next generation of bike lights. they can shine a laser light in the street and provide normal functions but the question is, are they any better? they are all yours to give ago. so the conclusion? you got the brake light which lights up as you slow down, presumably because it's got to mix barometer, it's very impressive and when you are in cyclist, you worry that people not noted sing when you come to a halt. left right indicators, there are so few cyclists use that as a method of indication, i haven't seen that much and instructions say, don't rely on this on its own, also got to use the arm. that would me. they are very, very bright lights. there is almost an arms race in cycle lights. brighter and brighter and these are very impressive. welcome to the week in tech. it is

the week google released its latest operating system. an indian ridesharing revealed plans to move to the uk by 2018's end. and it looks like master chief will be getting his own tv show. halo live action series will go to air. it was also the year that alex jones and infowa rs were removed. also the year that alex jones and infowars were removed. the conspiracy theorist was removed from several platforms the using hate speech. twitter didn't follow suit stating it hadn't violated its rules. facebook debuted its our messenger games allowing people to play games in group chat. it does paris brighton resemblance to snapchat‘s sna pables. small squishy

spider robots for reconfigurable pneumatic hydraulic devices. eight lego box body is made entirely from silicon and fluids are pumped into its legs to make its move. the team hope these kind of micro— bots could be used for delicate surgery in the future. and finally, research as have taught an ai how to dribble. no, not likea have taught an ai how to dribble. no, not like a baby, our basketball. the team from carnegy melbourne university in deep motion inc used to motion capture to approve this bill is about virtual player. slam dunk. no summer party is complete without a warm bottle of red wine. did you know if you open a bottle of wine and don't finish it within a week, which is possible, the air that gets into the wine starts to turnit

that gets into the wine starts to turn it and it doesn't taste as good. instead, you might like to use wind poorer which are clamped to the bottle. this only works if it's got a cork, not a screw top on the top so what you do is you clap it there and drive at being bashed at the net needle through the core and into the bottom and when it's time to floor, this thing pumps argon gas into the wine bottle instead of air and that lets the liquid out but then there is no air in the bottle to make the wine go bad. then, when you take it off, rather violently, there is pretty much no hole in the cork, so the wind doesn't come out. what a cork. cheers. itell you, the views from the top ofjohn lewis here in 0xford from the top ofjohn lewis here in oxford street are produced backpack villa, but they are nothing compared to what we have next. —— pretty

spectacular. 0ne daredevil is taking grand vistas to an entirely new height, literally. nick kwek went to marseille to meet him. that's right, i have popped down to france to poke about a frenchman's garage. we are in our workshop. it is where we do all our research and development. a formerjet ski world champion, frankie zapata has been at the forefront of water powered vehicles for decades. he has been beavering away the gears on several airborne inventions. i started with this prototype in 2011. two years after, i got the idea of the hoverboard. and then we got the idea to create the lie right. this is self alan singh. you just press the trigger and you fly. but recently he

has developed a pen shone for rocket fuel. —— penchant. this bad boy has five jet engines packed tightly together to blast frankie into the stratosphere. well, maybe not that high, but it can reach a top speed of 110 mph. we have a plan b for everything. band eight, plan b n clancy for electronics. and you can lose an engine. so if one of these five engines lows but you can lose two engines lows but you can lose two engines and keep flying. the explosion would the contained by some kevlar protection. the explosion? if it explodes. it can hold somebody weighing up to 100 kilos at 500 feet to six minutes. at $250,000 a pop, surely... it is not

something that we plan to cell. why not? if i tried this today what would happen? this one? today? you would happen? this one? today? you would kill yourself. right. a wired hand—held jaw streak lets him control his yaw and thrust, but it is his body which surprised the real conditional power. to stay on the board for more than 12 minutes you have to be able to absorb a two g force, with 25 kilos in the bag. no problem. you need about 1000 hours on that or not. the same as the water fly board, but 20 times more. how hard can it be? yeah! 0h, water fly board, but 20 times more. how hard can it be? yeah! oh, yes. yelping. about five days a week,

doing some kind of crosstraining. just to resist, with the stress, that you have in your leg. as well, he has also developed the easy board, a version with sticks, karalee being trialled by the us military. we did some tests with the us military. that was the first soldier we trained. the fly border is more like a demonstrator. that's my is more like a demonstrator. that's b, is more like a demonstrator. that's ou is more like a demonstrator. that's b you know? is more like a demonstrator. that's my baby, you know? it is my roman suit. tony stark. i can hear the jets flying up now. frankie is ready to ta ke jets flying up now. frankie is ready to take off. he's off! he's off! look at him go! that's amazing. see

you later, i am off on a hoverboard. and how does it feel when you are up there, flying around? it isjust out of this world. one of the best things i ever did in my life. to be able to do this you do have to be ultra— specialist and physically brilliant. so for me, that means sitting back happily on terra firma, enjoying the beautiful marseille coastline, with a man flying around my head. i'm getting a selfie. bright, time to see how lunch is doing, and i'm going to test the temperature of our stake using a meat thermometer. not any old meat thermometer. this is the meater, which of course talks to my smartphone. through the hour, you can tell it what you are cooking, what your desired temperature is, and it will monitor the temperatures

for you. and it will monitor the temperatures foryou. —— and it will monitor the temperatures for you. —— through the app. it will alert you when you are medium, well done, all raring to go. not long later the stake is really well done indeed. i hope you like the nail polish i had time to apply while waiting. now, from stake to chicken. go with me on this. day lee has been touring silicon valley to look at how some tech professionals are choosing to unwind. —— dave lee. across california there are as many as 60,000 chicken co—ops. lots of them are here in silicon valley. many are owned by techies because owning chickens has become something ofa owning chickens has become something of a status symbol. down there is one, they have one as well. we will hear more from him later. now, i've just arrived at my first stop. heather ‘s role at herjob is to help top tech executives communicate with each other. when she comes home, she commuters with her

chickens. hey, guys. come here. it is like digital detox. it is about as farfrom is like digital detox. it is about as far from tech as you can get. it ta kes you as far from tech as you can get. it takes you back to the farmland. my pa rents, takes you back to the farmland. my parents, i grew up on a dairy farm. this is a nice reminder of when i was a kid, back on the farm. this coop is a place of real luxury, a property in keeping with the mega homes that surround it. we built an irrigation system that connects to the sprinklers. we never had to fill up the sprinklers. we never had to fill up the water. so it kind of looks after itself? yeah. we fill up the feeding tubes in the back about once every ten days. and then it is just scooping poop and holding a chicken. they love to be held. isn't she lovely? her children are, of course, fully paid—up members of the smartphone generation. but they have a lot of time for their foul friends. it is about the only thing that gets them outside. hello. your

home, how is it going? i have come to see your chickens. yes, please. johan's dayjob to see your chickens. yes, please. johan's day job has to see your chickens. yes, please. johan's dayjob has him of the cutting edge of self—driving car technology, but when he gets home he likes to get his hands dirty. when you are working, not looking after the animals, what is a typical day? long days, intense days, lots of pressure. we want to do a lot, we have ambitious plans. it requires ha rd have ambitious plans. it requires hard work to achieve this. johan shares his home with a wife, for children, five sheep, 13 chickens. you are living in a part of the world were the latest technology is readily available and people are worried about how looped into that we are? how important is it to insure the kids get a sense of the real world ? insure the kids get a sense of the realworld? very insure the kids get a sense of the real world? very important, insure the kids get a sense of the realworld? very important, right? it is easy to them to just get caught up in this area, where there isa caught up in this area, where there is a lot of pressure, school, what not. looking after the chickens and selling eggs to the neighbours, at least the ones who don't have their

own chickens, is all about considering the value of removing tax from these kids' lives, if only for a small part of each day.” tax from these kids' lives, if only for a small part of each day. i can see the appeal to looking after chickens. getting back to nature. realising what is important. and for people in the tech business, it seems to really help. for people in the journalism seems to really help. for people in thejournalism business, not so much. i've got to put him down. he is going to pick me like crazy. though away. —— go away. that was dave lee, recuperating in silicon valley. i've never seen anybody is scared of a chicken as he was. that is all from our summer sizzler. i hope you've enjoyed it as much as we did. we live on facebook and twitter as well. now, after such an intense summer of sport, next week we are going to look back at some of the new technology that has been brought into play in the last few months. and we will leave you with one more

thing, which we hope illustrates the perils of filming someone going down avr perils of filming someone going down a vr waterslide. enjoy this. our cameraman nick kwak certainly did. this isn't working at all! good morning. weekend weather coming up, but first let's take a look back on friday, a day of mixed fortunes, with heavy way around for some, so much so that weather watches had to shelter underneath hastings pier get this dramatic shot. there was some sunshine to be found, particular cross the channel isles, as you can see at guernsey. there was this kind of changeable theme that moves us towards the weekend, in actual fact.

something that will be quite important will be the feel of the weather. that is because we have these clear skies moving across us as we speak. the air direction coming from the north—westerly, quite quiet. the showers disappeared. not much in the way of significant weather to talk about. temperatures are falling away. that is worth bearing in mind if you are up and off early saturday morning. likely to see single figures, may be low single figures in rural spots. a chilly start to saturday. lots of sunshine around. that bodes well for day three of the cricket. it looks as though we could get a decent day's play in there. perfect weather conditions for spectators and players. we have already talked about the clear skies, plenty of sunshine around first thing on saturday. as we go through the day the cloud will gather into the south—west. rain putting into south—west england and wales, eventually into the midlands. clouding over a little bit. sunshine turning hazy. nevertheless, eastern areas staying dry, highest values potentially of 23 degrees. the breeze will pick up a little along the west facing coast as we start to see the rain arriving through the evening and the overnight period. the rain will push in. a few bursts through the night. there is a level of uncertainty as to how much wet weather we are likely to see on sunday.

this area of low pressure still producing 12 headaches from time to time. it looks at the moment as though the rain is likely to linger first thing in the south—east. behind is that they will be quite a lot of cloud on sunday, a muddy humid field for all. isolated showers. if we get some brightness then temperatures will start to respond. and they will start to pick up. generally speaking, we are looking at them sitting in the local 20s. as we move out of sunday into monday, the area of low pressure still sitting out to the east. we are likely to seek showers around. as we go through the week this ridge of high pressure will build. it is an improving picture. after a slightly disappointing start on monday we could start to seek more warmth pushing into

the south—east for some on tuesday. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is nkem ifejika. our top stories: the saudi—led coalition says it will investigate an airstrike that killed 29 children in yemen — the un demands it be credible. in romania, tens of thousands attend anti—government rallies. more than 200 people are injured. turkey's lira hits an all—time low, as president trump doubles tariffs on their metal exports. an immigration reprieve for a 9 year—old chess prodigy — we meet the boy whose talents mean his family can stay in the uk.
