[000:00:00;00] sparks' upright hair from a blanket is all nothing compared to what else static electricity is capable of. recently, in the stavropol territory, a fuel truck caught fire during refueling, according to the preliminary version of the investigation , the driver's wool sweater was the cause of the pores of gasoline coming out of the tank mouth. it is enough for one spark to slip through, such cases are often recorded by a video surveillance camera at a gas station. where does so much static accumulate on clothes? everything that surrounds us consists of atoms, and they themselves are made of three elementary particles, negatively charged electrons positive protons and neutral neutrons usually pluses and minuses cancel each other out, so most things are neutral. but electrons are very light, and their bonds to the nucleus are not strong any friction can give them enough energy to

leave their atoms. they eventually become positively charged, and the runaway electrons create a minus, but nature strives for balance, therefore, when one charged body comes into contact with another, the electrons are immediately attracted to plus. their jumping is a discharge that us a popularizer of science from the polytechnic museum is attacked. maxim ivanov explains on a man's clothes. a charge of several hundred per slope can accumulate, a lot or a little of this charge is enough to make it flare up for a short moment. some kind of gas-discharge lamp, for example, a neon bulb of such a neon bulb, in order to light up, a voltage of 90 v is required. maxim placed 15 pieces on a special panel, in order for the entire chain to light up, you need 1.350 v. for comparison, ordinary light bulbs are enough 220

to electrify nylon tights, losing. about balloon. two pieces of cloth repel each other. so, charged equally we place on the foil. and let there be light, but why is the flash so short the charge that we have accumulated on nylon runs out very quickly, the charge is very small, so the flash is very short and it gives light in total. during this very short time , there are quite a few such charges, however , they are quite capable of igniting something combustible and can be deadly for equipment when working with sensitive electronics, they even use antistatic bracelets. they ground a person and the excess charge that occurs during work instantly drains from the surface of the body in large industries when working, for example, with a polymer film, a voltage of ten arises. sometimes hundreds of kilovolts. such electrification can damage the equipment and cause a fire.

special antistatic strips help to avoid this. they separate the molecules of gases that make up the air and are initially electrically neutral and ionize them, receiving positive and negative charged ions. this gives the materials the opportunity to attract the opposite charge, neutralizing the article, but this is a special technique. but what about in everyday life with clothes that beat with current, dispel the myth of accumulating static electricity, not only synthetic, but also natural materials can. it all depends on the ability of tissues to absorb and release moisture. the better the liquid is absorbed, the less stress. after all, water accumulates as a conductor champions in the accumulation of static charge, acrylic and polyester, on which the viewer complained to us in social networks. a miracle of technology denis varfolomeev even in the evening when i watch a movie. my favorite blanket is electric. so it is on this blanket that sparks come from him. we will check 10

anti-static electricity popular on the internet, the most common anti-static agents are for 50 rubles. but these already cost 2.500 and both contain polymer molecules, one end of which binds to the material, and the other picks up moisture from the atmosphere. the surface becomes small electrical conductivity, and therefore can make up for the lack of electrons by accepting them from other objects or vice versa. reset excess in stores and special sheets for washing for 1.200 and antistatic conditioners are sold. we chose the average price for 400 rubles. it is full of foreign methods , for example, treat clothes with hairspray, walk on it with a metal object, wash things with vinegar or rub with laundry soap, and home-made antistatic agents from water and hair conditioner are recommended on the net.

or aluminum foil balls during washing, they allegedly take all the static charge for themselves, which of these works will our masha goretskaya check together with the test laboratory engineer sergey ivanov? to begin with, using a special device, we will measure the electrification of the blanket, the maximum result is 5.83 kilovolts per meter , this is the permissible value, the permissible values ​​\u200b\u200bwe have 15 kw per meter, and as practice shows , we test samples of this value do not exceed cut the blanket into 10 identical pieces. the owner for the sake of science, allowed. we will immediately send four to the laundry with purchased and homemade means. for 50 rub. very sharp. but that seems to be its only

downside. antistatic worked even better , even the pom-pom for dancing, which masha took for clarity, now does not react to the fabric. and what about folk methods , an effective method, in my opinion, i used it at school when the uniform stuck to tights, is it hairspray. the main thing is not to take the one with sequins for 200 rubles. he coped and showed the result he lived better than a special spray for 50. and what about homemade antistatic from an air conditioner for hair and water 0.13 kilovolts per meter

, the other two methods, walk on the fabric with methodical objects and rub with laundry soap. we get a value of 0.23 kilovolts per meter , we traditionally check this with our works and this , in my opinion, is the simplest and most effective way. that is, you don't have to worry. just threw it in the wash. but washing with vinegar disappointed a piece of blanket began to smell bad, yes, and completely failed to cope with static. moreover, vinegar can leave traces. and some fabrics, especially natural ones, generally burn foil balls,

also showed a bad charge result is formed much more, we do not recommend this method. yes, and manufacturers of washing machines obviously do not approve of these. any metal objects. inside the drum , the winners can break, we have an antistatic agent for 3,000 rubles. then hair conditioner yes, mixed with water, but the conditioner also performed well. for underwear, it also showed very good numbers. yes, i also vote for fabric softener, because it is quite economical it. get rid of static electricity quickly clothes won't work. this is how nature works, but you can reduce its amount and air conditioners and antistatic agents from the store work best. they remove the charge and your favorite clothes, unlike home-made ones, they definitely won’t harm. and what surprised us this week

scientists and inventors from different countries right now on the air miracle of technology fifth place in our traditional hit parade of scientific and technological news - computer games for children. perhaps it is worth limiting, but not completely prohibiting, this conclusion was made by researchers from the karovinsky institute in in sweden, they tracked the intelligence of 9,000 boys and girls who were between 9 and 10 years old at the start of the experiment. they were tested for cognitive abilities at the start and after 2 years, and it turned out that those who periodically played on a smartphone or computer showed higher intelligence compared to those who did not. interestingly, watching videos or social networks did not give the same effect to scientists. it is said that their result is in good agreement with the data of many other works, too, which have shown that games can be useful for mind. at the same time, the authors emphasize that they are calling for permission to play no-limit, this

can lead to problems with academic performance and health. this is a miracle of technology further in our issue, ultrasonic with essential oils and poisons. what collars from fleas and ticks really protect pets, and at the same time do not harm. the novelty of the week is a camera toy for preserving childhood memories. is it true that she can recognize faces and sort from the filmed material a miracle goods fan that cools the phone or tablet, we measured the effectiveness of the device and evaluated it the practicality of the idea itself, as well as the best discoveries and inventions from all over the planet. the most interesting is yet to come. the provider is long overdue. include home internet in the tariff

i take on the challenge megafon unique strong, she is always there. your country is your home your family the traditions of your

people together. on the neizvestnaya rossiya tv channel about russia in a new way for all operators of the country soon this is a miracle of technology i am sergey malozemov and we are climbing higher in our hit parade of news from the world of science and technology, that on the fourth line to keep the summer cottage clean, robots will help the belgian company showed a prototype of a modified automatic lawn mower, which is now equipped with hands and can change nozzles doing also, for example, the work of cleaning the dirt from the terraces or picking up cones, leaves and

other debris, as well as pulling out weeds and collecting at the direction of the owner he needs vegetables or, for example, fallen nuts. in all this, the robot is guided by cameras and artificial intelligence, the authors. true, they admit that it is completely a work capable device. they have not yet created and continue to experiment. a carefree walk with your pets in the fresh air. aport but then what every dog ​​owner knows about the problem of fleas and ticks, which do not tolerate up to fatal infections advertising.

as a solution, he offers special collars with essential oils , chemical impregnation and technological ones such as ultrasonic ones. it’s interesting that oksana sobina breeds a mantipa from this . oksana loves and treats small children with food and scheduled walks, and to protect against fleas and ticks, she buys active advertised collars from germany for almost 3,000 rubles. and a spray with essential oils for 1.500 and nods, especially attractive for bloodsuckers, axillary inguinal regions and withers for many years we walk in parks. we walk in a country house, and dogs run through the fields and in the forest and never a single tick on the dog. we did not catch a different approach from

the culinary blogger elena shamugi. she abandoned expensive collars in favor of cheap ones, which she changes every 3 months and examines her cat marik and dog harik after walks elena established after i almost lost my beloved chihuahua, who wore a german collar. just like oksana's, this collar let us down a lot, we caught a very good tick. uh, the dog got paralyzed. he lay all day at one point. he simply stopped moving, and they were already going to take him to the veterinarian to the clinic and remembered about the russian- made penny remedies and i just divorced him by eye. although the concentration has made much more. what was necessary by its weight and literally 15 minutes later. he got up a little, very slowly went to drink water.

harik, still got off lightly, ticks suffer from victoria, ehrlichiosis, anaplasmosis and encephalitis, even one bite can be fatal; however, dangerous and other skin parasites of fleas carry many types of helminths, which can also significantly worsen his place with the animal and, in general, the quality of his life is a bite. uh, just one or two flea kitties. it can itch absolutely everything, so how to properly defend yourself for our test. we took four options collars with simultaneous protection against fleas and ticks. domestic production for 250 rubles. according to the action, it is impregnated with antiparasitic substances, which must act for at least three months. the one from germany for 2.600 at a discount manufacturers promises efficiency up to eight months. collar for 455 rubles. with essential oils of lavender, citranella, eucalyptus and

tea tree, they should scare away parasites and a technological version of the ultrasonic keychain for 2,500 rubles. the human ear does not perceive the frequencies emitted by it, but fleas and ticks, according to assurance sellers are afraid of them. the fearless employees of the all-russian research institute of parasitology agreed to help us in testing with the warmth of their hands, they literally awaken the ticks for the experiment. and what do we see? one even fearlessly climbed onto a piece of materials that would either scare away or have a deadly effect on a cheap sample from a chemical arthropod; the ultrasonic keychain interested the tick and also did not scare it away. maybe he doesn’t make any

vibrations at all, if i were in shoi, you are already from this distance, i wouldn’t hear anything measurements of our permanent expert. physicists vladimir reshetov fix the device, as stated, emits ultrasound with a frequency of approximately 40 khz. but it's like, they say, a scientist from the scientific research institute of parasitology is useless, as far as key fobs with ultrasound are concerned. i have not yet heard that any key fobs worked effectively, they often appear on the market, but we have done a number of studies so far. uh, ultrasound doesn't work. there was no noticeable reaction to ticks and an expensive collar. but one out-of-competition sample

still influenced the behavior of the subjects we pay attention to how the tick crawled at the beginning of the experiment, how it begins to be cautious and literally. e, very timidly begins to move, but with paws. this suggests that the tick is disoriented, the so-called knockdown effect of this collar is not yet on sale, it is the fruit of the work of scientists from the institute. what miracles of chemistry are in its composition, is not yet disclosed, by the way, only after contact with this collar ticks. the next day , the pathogens on the restaurants of diseases died. these organisms are very clever. they change under the conditions of e, external environment. adaptable and adapts very well, so the development of new preparations based. 12 dosage forms are also an urgent task, and

the pharmacological sciences, the scientific community is still looking for one hundred percent effective means of protecting pets from fleas and ticks most effectively. according to international studies, they destroy parasites and midoclaritis paired with lumetrin. they are in the composition of the perforated collar and fipronil is contained in the contestant for 250 rubles. but there is no guarantee that these substances will be the same work well in different regions where bloodsucker populations are not similar and will not harm the pet, for example, permethrin, which is sometimes impregnated with collars, can cause seizures in cats. and the essential oils of tea tree or citrus can poison and allergies with redness of the skin and hair loss, so the veterinarian should choose the means of protection, taking into account the breed, the weight of the sex of the animal, so that it is better to protect your pet, it is better to use several methods at the same time.

i believe that the maximum efficiency showed the use of tablets and, accordingly, barrier methods, such as collars or drops, tablets and drops make animals less attractive to fleas and ticks, but again, not 100% . as for collars, they must also be put on correctly close to the skin and do not forget to remove them before washing after each walk, animals. it's still best to look closely. and then there is a chance that not a single parasite will poison the life of your beloved pet and yours, respectively, do not miss the novelty of the week, children's a camera from a french startup is attached to clothes and records first-person. how long will its batteries last and will be dissatisfied with the quality of shooting, parents and professionals. the videographer asks if she will rip it off? miracle

goods column about when advertising is true, and when not, we check the fan that is attached to phones or tablets and helps to cool them, does it prolong the life of the gadget and is there any danger to long salmon? yes, sucked on the shore. the main thing is that neither ear is torn off, and also the most amazing discoveries and inventions leaders of the weekly news hit parade bright taste of instant coffee, jardine gold and jardinc, the pleasure of feeling the best. the morning starts with the best breakfast. well, maybe it's better to take only fresh products, select good chicken fillet and add a handful of smiles. a spoonful of useful tips we tested several options. i personally had a case of

has decided to change the angle and save the first childhood memories just the way the baby saw them . it is attached to clothing, records first-person video and saves it to the internal memory in active battery mode lasts for 2 hours while sleeping , the gadget can work up to five and turn on by a motion sensor. but most importantly , advertising assures that the camera will take over part of the processing of all tons of footage. she knows how to recognize faces and group. frames in folders svetlana and vitaly kosyanov , happy parents of three children, timofey stephanie and a seven-month-old bazhena, are filming them like most on a regular phone. do you like the novelty? we invited the family to the entertainment complex and asked them to arrange test. the first problem that svetlana and vitaly faced was to mount the device according to

the instructions to attach it to clothes using double-sided tape. it is included in the question. will she tear it off, of course, the adhesive tape turned out to be not sticky enough ; the specialist replaced it with a plastic holder, also from the kit. now the camera is firmly fixed on the dress, we turn on the divine control. whether it is well directed is immediately impossible. this can only be done later by connecting the device to a computer. let's see what happens mowing. and we ourselves while we check how the camera turns on from sleep mode to the movement , our testers even kartamysheva nikita sukhanov and pups play the role of a young family that got a dog turned out to be a camera that really reacts to any movement. it is quite sensitive so. and, if we move away now, everything does not write again, although the dog. look, right up close, the view is small , a wide-angle lens would do. well

, in practice, while parents had fun with their children. they didn't see what the camera was recording. they did it. we are after the fact it turned out all the time in the frame was our film crew hands of god's ceiling, but not the faces of relatives. here timofey comes down the hill and meets his sister in her mother's arms, but the camera did not capture this meeting. the most vivid emotions remained behind the scenes. let's try to put the car in a toy car. dad steers the device, but again the ceiling of a part of the car and only for a short while mom gets into kasyanov's frame . it's just not needed. well it

a toy for 2 days to see how it works and put everything in the far box, yes, to prepare the gadget for work, an additional gadget needs to be charged with what concerns the watch phone, somehow you use it constantly, you charge it, and it seems to me to charge such things, then when well , you need something, but maybe a professional and they can do something with it. having found a creative solution , we asked anna barkova, a children's videographer, to evaluate the quality of filming and, if possible , to mount a memorable video for the family. guys and the faces of the parents will be visible, anna is shocked to see the material of such poor quality. she hasn't had an hour-long shoot yet. she found only a couple of good seconds, a lot of noise on the video, stabilization. weak, everything is shaking, honestly would not advise. it seems to me that this is money thrown away and the promised face recognition of relatives with the distribution of files into folders, of course, did not work. everything that was taken was thrown into one heap. in general, as a result, the adhesive tape does not stick

to the clothes fixed by the holder. the camera collapses and shoots whatever really important. as a result, it doesn’t get into the frame, which makes the whole idea meaningless. our rating is 0 stars out of five. on the air , watch the miracle of technology after a short pause. the tablet and phone are overheating we will check if the gadger fan will save it, is it a miracle or not a miracle, as well as the top line of the hot five of the world's science and technology news, what did we find the most interesting this week? change provider. it’s high time tele2 lock three times include home internet in your tariff it’s easy to connect and you don’t even need go nowhere. come to the side of home internet tele2 moved to the moscow region from the caucasus 15 years ago and during this

finish in the extremely busy tokyo bay, the length of the vessel is 95 m. loading 750 t, a remote operator was responsible for communicating with traffic control services. he is at the direction of the port services. spread corrections to the course. the vessel previously demonstrated the same japanese concerto unmanned tourist a bus, an anfibia and a ferry capable of mooring itself and leaving ports. many thanks to everyone who writes to me through the tuto.ru website and social networks, let me know if you see an advertisement for some interesting, but distrustful device. we will definitely check everything and say a miracle or not a miracle. surely you have noticed how a tablet or smartphone does not like to work under the scorching sun. and they also overheat if you open energy-consuming programs. and in addition , it is almost

impossible to connect charging at this moment, after warming up the device starts slow down and this is not only inconvenient, but also dangerously high temperature shortens the life of gadget parts, it is easy to cool electronics, it promises such a chinese device for a thousand and a few rubles, a small fan can change the backlight and works in three speed modes, a maximum of 6,000 rpm is attached using suction cups and a safety hook is charged via usb in 60 minutes. and then, as it says in the description , it works for 3 hours. how necessary this thing is, at our request, a student undertook to test fedor harnesses the bauman technical university. he often plays on his smartphone and tablet. and he knows firsthand how hot they get. it is very unpleasant to touch the phone when it heats up and the root starts to sweat there and it all turns into a mess with the device overheating. well, they coped with the usual folk methods. you just

play the phone like this, and it overheats here. now you don't have to do it all. play fedor after 10 minutes, using a pyrometer , we measure the temperature of the tablet 43 degrees , put on the fan. good result for minute it was possible to reduce the temperature by 11 degrees, repeat the procedure. only now cool the tablet. let's be natural fedor stops playing and gives the device a break for a minute minus eight degrees is also not bad, but you need to interrupt the game. and whoever likes it, the fan is clearly better compared to folk methods. if it is too hot outside, it will be hot everywhere. this device, of course , will catch up with cold air. and that is , the window sill no longer works. that is, while this device works constantly to blow on

device. this is also unpleasant. this also causes banal discomfort. and better. i 'll just bend my fingers a little and play. e with this pleasant breeze than constantly being distracted from the game and constantly blowing back and forth, and what about a non-gaming application, the karaoke taxi driver georgy liang uses the phone constantly and often heat , adds the sun, sometimes it blows hot air directly from the stove on the gadget and you need to run a lot of applications, including maps and special applications. then the messengers do not have to charge it yet constantly and from this there is heating , let's try to correct the situation with the help of a fan, our testers masha goretskoy and nikita sukhanov are here not only to sing, their task is to check how much

the phone cools down. well, that's it, change the microphone to the meter. mm 38.6 our phone hurts. in fact, with an electronic patient, everything is not so scary, the acceptable temperature for him is 35-40 °. now turn on the fan in the turbo. a minute later, minus one and a half degrees this is not particularly impressive smartphone by itself for that same time cooled down the same way. georgy didn't like that the fan blocks the camera and now the phone doesn't fit in the holder, apparently, the cooler can really come in handy only for those who play, but even this application is an expert. it seems doubtful that the fan cools the case, but not the stuffing, as a rule, the most heating parts. we have this cooling device on top. we cannot use it from above,

because we will cover the camera or from all sorts of cameras and its fit will be minimal, if we are talking about a tablet, then its cooling capacity is practically reduced to zero, because, again, the tablet has a large surface of its own. e, which exactly removes the heat, yes, and if we are talking about tablets with a metal part behind it is corny to attach it somewhere. but if only on some part, where most of all there is a warming up. well, again, not the goal. in different ways, the only sure way to help the device cool down is to reduce the load, for example, you should not play or watch videos and charge at the same time, and if the gadgets give a signal that they too hot to ignore. it does not stand between the motherboard and the heat sink ; heat sink paste is also applied, in addition to this, by the manufacturer. a limit is also set. that is, if

the device is very overheated, then it goes into device protection, which tells us that an error has arisen and the device turns off. we have questions about the security of the device. nonsense fans spin fast smartphone often turns out to be in front of the face that if the user has long hair check it out our brave tester even when the car, by the way, everything is fine, nothing gets there. guys sucked on the earring now. the main thing is not to tear off my ear, the feeling is real, as if someone took it and pulled me hard. in general , long-haired, we have nothing to fear. but, if there is, such long jewelry or a long manicure, then there is a risk of breaking one of these. in addition, during the tests , it turned out that the suction cups can come off, and

the safety hook. even with a weak jerk to break away. in the end, our verdict is the fan will indeed work for three hours and reduce the temperature of the gadget, but the cooling will be superficial and will not give much effect to extend the life of the device. it’s better to take breaks in games to pay more than a thousand for a dubious design. it seems to us that this is not a miracle. well, now what news from the world of science and technology we recognized as the most interesting this week. first place - hot five, one of the most common and formidable eye diseases, cataracts, perhaps to cure without surgery with clouding of the lens in experiments on mice , drops successfully coped with a new drug developed in britain improved the vision of 61%

of the subjects, increasing the transparency of the lens by an average of 46%. however, some types of cataracts have not responded to such therapy, and the operation, which ophthalmologists have mastered well, is still the only way out in these cases. and now on your screens is the question of the weekly quiz. just check yourself or answer the bills in the qr code with your smartphone and follow the link. choose the correct answer and win. one of my books, in which there are a lot of interesting scientific discoveries about useful, safe life food, strengthening, health, and delicious recipes , the winners are determined every month among those who gave at least one correct answer. and the more hits, the higher the chances, drawings and discussions of the correct answers on the pages of our program on popular social networks. well, those who win, we will immediately call. so don't forget to enter your phone number after answering. voting is over with the correct answer on

your screens. thanks to everyone who participated, next question in a week. can become bad blood vessels drugs helps to improve microcirculation, reduce the risk of blood clots, relieve inflammation and strengthen the walls of blood vessels. hi all. this is the country answer. i am ilya for the fall, our heroes guzivs moved to the moscow region from the caucasus 15 years ago and during this

time they got used to everything except the gray sky above their heads. today. we were lucky sunny clear day and we have such days in our lives let's add heroes to these small windows , replace the interior with strip glazing, make it dazzlingly white, like mountain peaks sparkling in the sun, go ahead. when guzeeva moved from karachay-cherkessia to the moscow region, they carried things in bags, and recipes for traditional caucasian dishes were in their heads, an appetizing apartment and aromas were heard in this house already from the threshold of hello. hello. hello, hello, hello, we are waiting for you. hello hello i'm glad. and we are so glad. we are exactly how we felt. this is what sizzles like this in your kitchen, this is what we have pies called syen fillings are different in our case. this is a potato with salted cheese from the meadow. it is very appetizing
