of worship is attended the south and finland is hiding to the poles, to elected government. sosa, democrat, prime minister, santa marinas, hoping to secure a 2nd term in office, but she's facing a strong challenge from the far right. and that's all for me for now. coming up next, doc film explores the science of explosives and don't forget this or miss more news on our website. that is d w dot com and our social media handled is ad d de leon use. i monica jones from the team. thanks for watching. when you work as an architect, jacqueline, or not at all women in architecture, why are they so invisible to the larger public? we decided to ask them. the press is, what is the poetry the secret of a house?

shattering the glass ceiling. women in architecture starts april 20th on d. w. for 1002 years ago the chinese made a discovery that changed the world ah explosives. for centuries they were used to kill and destroy. but explosives can do so much more. they save lives and take us to the stars they thrill us and make room for something new. millions of tons of rock a mind every day with explosives. without them our worlds would be very different.

ah. ready ready ready ready germany, this is the white giant, a rundown apartment block from the 1970s. ready ready ready ready the city council wants to have it demolished. ready martine hopeful will carry out this task. he's one of the most experienced to demolition experts in gemini. it will be his last big project because he wants to hand over his company to only come motus. she's already started planning the demolition. now they want to inspect the 6th floor rica, motus is afraid of heights and doesn't enjoy writing the elevator. but martin

hopeful is having fun. oh, you can see that we're above the tree tones lou old in the 20th floor is a great lookout. once you get a magnificent view across this industrial mask with joe montes is glad they only need to go up to the 6th floor. their workers have already started to weaken parts of the walls. this will make it easier to bring down the white giant. the 29 of those, some with salmon, him to some bow holes are still missing from home. let's see. it was magna, it's documented. and oh good was they want to blow up flows 6 and 7 on kind of you can imagine it's like a tree. i'm all remember to follow tree honey to cut out of which is how and that's exactly what we'll do here. and taylor blast out a, which i forgot. so this is the high rise was, will blast out

a wage. so falls down the even plan to have to which is one in the basement and one on the 6th floor. so the white giant collapses in on itself. the whole process should only take about 15 seconds. no single misty, it is not as it were. kindergarten, children who rec, other kids towers, oscar for people often ask a solution, don't you have a problem, but you're always destroying style shopping blocks that know we're making room for something new about them that makes us happy as well. conditions, revulsion, this demolition will shape or rica. marta says future korea because the industry is closely watching what's happening into spoke children house in germany. deep in the forest lies a well hidden research site. here scientists develop explosives for military and civilian purposes. a so called hollow charge

designates in a bunker with enormous force 3211 blasting engineers all over the world. use hollow challenges to cup through steel. with tremendous pressure. the explosive liquefied sits copper casing and drives the particles through the steel. this charge has forced to hold through 17 sick metal plates. the stars diaz was pan dormant. steel is or behave like a liquid. this being displaced by the explosion due to the high velocity of the particles emitted. it wasn't political. the liquid copper cut through steel like a knife hollow charge is that the best way to blow up stretches made of steel. in

the elaborate tree, the engineers can design explosives for almost any purpose. these gray blocks contain explosives mixed with alan minium powder. this creates a lot of pressure and is useful for blowing up buildings. a lot has happened since explosives were invented 1000 years ago. at that time, chinese researchers mixed so peter, sulphur and charcoal, the resulting black powder was 1st used for fireworks and later for warfare. black powder only detonated when its constrained. then it develops its explosive force and burns at 300 to 600 meters per 2nd. around 800 years later, the italian chemist, oscar neo. so guerrero invented nitroglycerin. it's an infernal liquid that already

contains all the ingredients for an explosive reaction. it's 4 times stronger than black powder, but very unstable and sensitive to impart. there were many serious accidents. sererow himself was injured so badly that he stopped his research. but some one else continued. alfred nobel, he wanted to use nitroglycerin in mining, but he paid a high price. in 1864, his brother, a male, and for others, died in an explosion in the laboratory. legend has its no bell finally finds a solution by chance. while in transport nitroglycerin leaks into a cushioning layer of grated diatoms. the resulting mushy substance is safe to handle. dynamite is invented also as a team on kind of our systems don't have a few words where you contact my them with the lighter. yeah. okay. that wouldn't

work because the kinetic energy of the lighter wouldn't be enough. people to be meters are explosive the discussion initially. i mean it's you what makes them very slave? the so guns we don't ignite with firma lynette it's you but with pressure mid machine . okay, so let me talk modern explosives, need a detonator that triggers the chemical reaction. this tube contains a multi stage explosive device. a glow wire ignites the trigger. this sets off a range of increasingly powerful charges until the explosive finally detonate. the headquarters of martini hope. first company in east, in germany rica, mattress and her boss have returned from the white giant induce pork and now finalizing their plans. meanwhile, an engineer is cutting destination cords. these red tubes are filled with an

explosive. they will need several 100 of these detonators for the white giant. they marked down each charge with its number and position in a large table, the bottom. okay, okay, good. martin hop fer pause over the demolition plan which still needs the approval from a structural engineer from dr. mill's to just confirm the structural stability. sasha, great. this isn't a sack. was a household as well? yeah, i guess project was a huge challenge that we need to factor in a bunch of things all at once. these are starting with the crime to conditions. i my, the blood fired msm does. we only have limited space available off of who gone to the right of the white giant is an underground parking lot that must remain intact in front is the st. hope for and matters have developed a bold plan. they want to fold the middle blocks fast and then let the outer to tip

into the resulting gap about the explosive challenges must not interfere with each other. additionally, the left block must also be folded, otherwise it would be too long for the gap. yesenia pessimistic doesn't, we're not pessimists for them on. so we're always optimistic during the planning. oh, but you also have to keep your eyes open for problems and you simply cannot leave things to chance during demolition, which we need to discuss everything in advance understand and we're thinking through wasting. then we're able to bring down the building safely, the spot we go fuel to the, to drive to the company's explosives warehouse to pick up charges for a test blast. it's a missile defense bunker that's no longer in use. only few people know the location where we come,

artists and martin hope for work quickly. the explosive story here contain night traits which causes headaches and they still have a 4 and a half hour drive to do, spoke ahead of them there. they want to do blast tests on some walls of the white giant to make sure that the explosive charges really work. potsdam bothers bags, film studios, lights, b, r a phonics, something's not working. the car should have made a spectacular jump, but the mechanism got stuck. power placing is a pyro technician who worked on the special effects in major production, such as game of thrones and die hard

left. so special effects are the go to company for a big bang. to day the team is working on a top secret production in which a car is supposed to explode. dog optically, the client is expected on said tomorrow, then tune all season song will shoot out the doors years old. not up. we have so called launch pods here with a counterpart in the door when i put a load of black powder in the large pot and that was low this door like she clenched will also use explosives under the car. quite a big lot less of a lot of money to destroy anything or to create a shock way from the talk village. we had a bit of dust and then the viewer sees, there's something happening with shallow locally, the prostitute was hidden in the trunk is a compressed air control to make the car jump. a total of 17 different effects will create a perfect illusion. while his colleagues work on the car pricing prepares the explosives in his workshop. so yet been via dish blanks,

nor loudon fort loudon. so now i'm going to prepare the load will put onto the causal. i'm fixing the detonation called in the form of a smile, fingered, and former snicker here off decides to exempt, so the force will then be distributed across the surface. i should for t. iron power pricing uses the same type of explosive code that will be used on the white giant. however, this code is my center, so nothing happens to the car. so i'm, it took me the lot on. so the finished load that's going under the car to generate the blast wireless sightings when the technicians mount a compressed air hose with a funnel. what, which way do you want to do this? we'll create a large fire bowl inside the car. the funnel is loaded with pollen

because fine dust explodes spectacularly when ignited pricing is pressed for time because he needs to finish a project for another film. he's prepping bamboo poles with small explosive charges that will creates bullet hells a central push me quash playing loud on these micro charges. i'll take one out a so called cylinder 6. looks pretty inconspicuous that they can fire job like we're talking about $300.00 milligrams hedgeland lakeside selina, this cylinder sinks is used to create large bullet holes rings on branches which day we have them in a range of sizes. and in, in washington colson sourcing. this is what our disks look like. classes are. so this is the classic charge for body shop, sir. decry the power of this tiny thing also is enough to rupture a club back to. so she isn't to liquid and worked his way through a piece of clothing, though it's weak enough not to hurt anyone. as alice walk and walk on how many

months of pallets, small lead plates sit under the explosive charges to protect the actors. the bamboo is not protected. on the contrary, i don't test this out in a band. the guys go just as a yoke and all this is exactly what we wanted to harden goals. we wanted to rip a large piece out of the bamboo. what and she materials in soft material, i her flying on me wanted to see this ripped open, that standby in blindness tires. meanwhile, pricings colleagues prepare the vehicle. tom teela puts the cardboard with the destination cord under the car. next to it, he places 2 small metal containers with gas cartridges. they'll create fireballs to cover the hydronic ram that makes the car jump. pricing

will trigger the effects by remote control. the engineers are putting in the doors, but they won't shoot them out until tomorrow when the customer arrives. because with explosives, you never know if you get a 2nd chance. on guess what? they're attention. this will be very loud. i'm counting down 3 law to i won't go. the shockwave under the car worked. the pollen exploded and the gas cartridges ignited . but the car didn't bounce. that when that wasn't enough, the bar from it. the technicians look at a video of the explosion. one shot was one hit. if it it jumped it behind absolutey. they only have until

tomorrow morning to figure out the problem. to are in western france. this is one of the largest granite quarries in the country. here engineers blast $6.00 to $7.00 times per month. the quarry provides hundreds of thousands of tons of rock and gravel for road and railway construction. the quality of the material is so good that it's used all over the country. 3 large dump trucks feeds a gigantic stone crusher. it can crack boulders up to one and a half meters in diameter. the crushed stones then fallen to a conveyor belts ready for further processing. however,

the blasting engineers into our have decided to try out a new approach to increase efficiency gold doors and you'll demean the comp would read the blog if you execute to plaster. and as is the case here, the boxes to pick re duty of we have to break them up after through the stone crush . elsie or this is a mechanical device, the costs much more than using explosive direct lender expose e for the electoral t l he been now has developed a method to perfect blasting inquiries. first, he placed his market boards on the quarry edge. they serve as guides for the drone that's about to photograph the terrain. the air craft delivers images from various angles. it flies a predefined course and photographs the edge of the quarry.

after about 5 minutes, the job is done. thanks very much me welcome. using the image is still, he bene calculates a 3 d model of the blasting zone galleries, yen cell punchy barrymore affair. the software is primarily used to design the plasticity of the data from the drone allows us to accurately calculate the geometry of the fracture. the software also calculates how the pressure will spread . thank you and where crocs are likely to form on time. based off of that, you said, you mean we can optimally place the draw hall's food so that the energy is distributed as even the as possible. be shown the energy so bruni form was here. the software calculates the exact distance between the bow holes and the amount of explosives needed for each one. the operator on the drill rig receives the data on a usb stick. not only is the exact position importance,

but also the angle at which the holes drilled. the machine drives 17 meters deep into the granite. there needs to be 49 holes drilled by tomorrow morning. ready ready ready in do spoke mat in hop fan and already come out is worry about the white giant. ready they've already logged the detonators and challenges for the test blast into their system. now it's time to check the walls. to deal with this wallace as we might have interfering. was it so by it was m come right michel joe? yes, that could influence the collapse. does this is off that doesn't matter for now, i only want to focus on the black, credible, believe you, we don't have any problems with marvin. and here we'll have to talk with the planner about what we can change, and where are your test blasts in this area now?

whoops. when you're here, the thirty's, there were the $35.00 would from all that start. the problem is that the middle blocks need to come down while the out to ones have to remain standing for a moment. the critical points of the joint walls between the blocks. if these walls collapse, when the middle blocks, the demolished the outer blocks could toppled too soon and crashed against each other, then debris would fly around uncontrollably. this must be avoided at all costs. that's why the blasting engineers now conducting a test in the basement of the white giant. they have chosen walls that have to be destroyed before the blast. anyway, said the building can collapse more easily. they're trying out 2 different methods in one spot. they place explosives directly against

the wall and then cover them with sand. when ignited, the charges should push against the sand and destroy the wall. in a 2nd location, they drill holes into the walls, which takes a long time. these holes. so then loaded with explosives, vista, it's important to see what happens when we demolish one wall. i know one because the other one must remain standing according to how we planned it except one fuse 2 tests for madison miss martez, you'll take over i'm sure we start and go ahead. let's say 2nd classic now i am almost 2nd blah signal ah.

attention, all posts all come back, 321 technician will complete. my problem is my side. now comes the moment. if trace blue tension is mounting at the potsdam baba's bags. film studios, how coursing and tom taylor prepared the car, their client is already here, or to comes up to talk under other effect today. it's absolutely crucial. it all the effects we've planned love happen at exactly the right time tom. we want to win the client's hope and what's on demonstrate that this will be the scene that they'll get on the day of shooting. andre talked on to the client will say yes or not, or couldn't. what's on yoda 9?

luckily they found the faults in the air jack yesterday. an engineer had changed something for another project and hadn't changed it bag das for these charges who shoot out the doors crossing quickly prepares 6 black powder challenges and installs them in the car. does captain schwartz per line that goes into the black powder? put the igniter in them, close it. that's a finish charge. so it does really it's, i can kill ready as a lot of power even like this. you body, it's what i need more power and i want to move steel dos. alpha is called me of holla and i fear sky. so i'll start typing it as a function and it's a table. this charge will shoot out the trunk. to be on the safe side, the technicians attached a steel cable, so it doesn't fly too far. although black powder burns relatively slowly,

it develops a high pressure. everything is now ready. your oil rolling your line. right. so i'll go ah, the fuel technical to help with the find finding include our techniques were great . the client liked it. that's the important thing. after 4 seconds, even though we saw all our efforts produced a great bizarre jeep and then what's it on? don, last us the scene will be the grand finale of the film. into all the preparations for the blast reached the final stretch. a special truck quiz

10 tons of explosives has just arrived at the quarry. the engineers use a trick to make the transport safer. there are 2 separate tanks on the truck. the liquids inside only become explosive when they're mixed together. t as a banner and his software did the groundwork now blasting and ginny, as you play more takes over you see coming from the low wheels, you may see yes, said spun to press the button holes, a blast. as of course, the gall, we're working towards it, but it's only a small part, so it only takes a 2nd renew, but a whole week of work goes into that one second focus i key. so our motivation is not just this moment. i'm old. we really have to take care of all the status in a few 1st,

the work has prepared the bull holes. the sate quite cylinders a night tra glycol, a common explosive inquiries. such a charge can crumble a massive concrete wool. but here they only service boosters to ignite the liquid explosive that's now being filled into the bo holes. in am, i meant t as he been now, we'll find out whether his software is superior to the experience of the local demolition experts. the explosive mixture on the truck is a rather slow burning explosive. that's because the engineers want to generate a uniformly high pressure in the rock, which will create many cracks and crush the granite wall. ah.

blasting engineers, you blame, gives the order to clear the area. ah, he will designate the charge is by remote control from the top terrace of the quarry. ah, 2 ah $40000.00 tons of granite have come loose. that means 4 days of work for the excavators before thou need new supplies. together with

a mining engineer, t eli bernard surveys the results. we got all yellow has been done. jeff come saw the results of the blast is as expected, the movement of the rock masses was well on the control. the chunks didn't fly further than twice the height of the demolition edge, which is how it should be. do the edge is nice and straight on the fragmentation is fairly homogenous enough all in all a very good last allusion to go, but most of that would you it's the triumph of technology over experience in the future. the corey operators will use t l e. bernard software for every blast induced book the smoke has cleared martin up, sir, and oh, he come at his wants to see which lasting technique worked better. first, the charges that were covered with sam's gonna

exactly the wrong way round the explosive challenges in the sand pile should have torn a hole in the wall. instead, they only caused a few cracks. the wall on the other side however, should have remained intact. they go take a look. i was a, does this does was we are resolved on world for years of you are. so this is what we were afraid of. it that the wall that was supposed to be destroyed, hasn't crumbled done with the wall that was supposed to remain intact. has crack names either. how to your plot that endangers that collapse process undefended in fog road or the direction of the forefathers con basil possibly. now they checked the wall with the boar holes glasses. these are fully ranked. this test destroyed the drilled wall and left the other one intact was in a positive a rush that had wanted to be that were positively surprised. we wouldn't have

thought that the wall behind it would remain so instead of them, there are no cracks in it at all. if you look at it from the other side, there's nothing to see. one of the material, blue eyed exactly in the area with the whole soil global one of either he's the house or the issue that we were facing with these walls has now been solved on the thank in duluth. yeah. now know how we have to adapt our technology and how to proceed, so it runs smoothly. this means drilling even more holes. there's not much time left until the grand finale. about 300 kilometers further south in bavaria. tom clear developed safety systems for cars,

pseudo colleague from ace to league mid. some owed them a very good colleague of mine at a fatal accident to this vintage vehicle on a country road like this one road was well and he wrapped himself around the tree. seems to want the worst thing that can happen. child is an old cause, have no airbags and certainly no side airbag. so i thought to myself, we should do something to the if a tree comes from this side of the alpha above and there's protection, or there has an airbag comes out, does was he opted some kind of just on the other guy was called tom clear is on his way to meet his team at a special test site for airbags stop the engineers use high speed cameras to check how the airbag reacts. it has to fully inflate in just 5 hundredths of a 2nd. ah, the onboard computer in a modern car conducts a whole orchestra of airbags there was

rekey, did it, you know, kind of as a collection has to detect there's a crash and then asked to reunite and in flight the correct her back or do i only need the airbag on the right, sorry i need were on the driver's side is oh, the side air backs or cushion. although there are all kinds of airbags that can be deployed however, the life saver can also become a deadly danger. remedy forces us months and it's susie, you often see people putting their feet on the dashboard. what are the large box? all them are well, far yoga and rid of course, everything that's placed back, it's ridiculously accelerated, didn't bring it, all your bonds would break really bad injuries via so it's, it's not worth putting your feet on there because it causes jones always wanted reason. are you likely wouldn't survive established? so it's my suggestions are here willing to induce book. the white giant is nearing it, sends excavators the piling mounds of earth around the building to catch flying

debris. the basement flows have been dug out, said the explosive charges can flattened, the high rise. martin hope for reviews, everything. he's nervous in the basement to engineers, a filling the last 4 holes. oh, yes. the challenge is don't, st. would get some detonating chord and a threading iron and put it in. come on, let's do something else. in the meantime. hopeful has wired up hundreds of electronic detonate. is that those and tried this? the idea, the crucial thing is the ideal. well, it's a unique number. every detonator has one open when we've programmed each with

a certain destination. tyson sites with a delay of up to 30 seconds. excellent. then bus is and bought out on heard. i've been blasting technologies. i embodied this is unique. so we're all excited for him or worry all, i don't know what to think at this point is, is move it will do. so we'll see on trauma, electronic detonate is a more accurate spit. oh, so much more expensive than conventional once. meanwhile, or rica motus is working on keeping track of everything so that these colorful pitches of the result of the few night shift. i sat here every evening until 12 she needs to double check 1000 positions on her list. but hope for now once to inspect the 6th floor with her. for ms. montez, please come here and i'll take care of everything else. light up the 6th floor will be blown out. there are hundreds of charges under the piles of summed what's,

what is a smokeless with us? we don't like it shortly before. gross was the ignition system again and conflict and check to see with all the detonate is hooked up to the main coin tosses guns. and i can all go through it again with mr. norbert, when no one else is in the building, even just us without plans double checking each floor again. well, come now just him tomorrow morning. be different fiegel when that's when the excitement cause when consulting i'll be fired out. ready ready ready 18 hours to go before the big blast. ready ready ready tom clear is now working on another project. he in his engineers the trying to better protect pedestrians in the event. this struck by a car. and again, they're using explosives. the problem is there are lots of hard parts in the engine bay beneath the hood. in the event of a collision,

pedestrians can seriously injure their heads. that's why ca, manufacturers have developed a so called active herds. ha, small explosive challenges. shoot up the hood during a crash. that's it. perfect. the hood shut up in a 100 to the 2nd blue. rid supposedly luther and now the how it is after mileage. this is the best position for a pedestrian to fall on to it and be protected from the hard components underneath the hood. we thought the will dog a sensor in the bumper detects whether the impact comes from a leg or from a sucker bowl. for example. it then ignites the explosives. everything happens so quickly that the hood is raised in time before the head hits the metal.

explosives are increasingly being used for safety systems. meanwhile, car manufacturers have even installed airbags between driver and passenger to prevent the 2 from colliding. first of all, these vans any vicki vile, via mich brings to hold a drive. middle explosives and cars are important. so, because we can generate extreme speeds to achieve a sir. now with the insulin, these to be detected allows given the signal evaluate image. and then an airbag, for example, has to be ignited or the hood has to come on. i need incredible speed to deborah and high pressure and force get only explosives can do that. under sprinkler manufacturers now, even develop external airbags to protect cars from other cars. so there's more to come. ready ready in this book, the time has finally come. martine helps instructs the security guards as one basil

. it's possible that the building tips the wrong way that can happen when you and it can't be ruled out 100 percent failed. the 2nd danger is that we generate vibrations or firstly through the blast at salvador, but also through the collapse of the building. schultz. that's over $40000.00 tons of concrete that will come down the door that will rattle the ground a bin. okay, you'll notice that notice bell and something could fall from the building due to the vibration house. when please think about your safety and it was a shot it, they haven't even laid the main ignition cable yet. this bomb it was. we have to do that now. with michelle right now was oh, with my with her 2 years now. the 2 engineers from rica matches his team need to quick. he went up to the 20th floor of a neighboring high rise and set up the master control. they chose this location because it offers the best overview the convert of can below the ignition court

dogs. lawson. yes. despite have fear of heights. motus would also like to be up that to press the button. but hope for once they're on the ground with him. he's worried that she won't make it down in time. if something goes wrong. charge the house line was most charged to his line. above them, off the water fountains captured the dust. ferguson missionary. okay. to fire crackers the set off beforehand to startle pigeon said they don't get buried under the rubble.

maxine hopes is lost. high rise is history hall ma ma. let's take a look at what happened was swindle bazillion. the engineer's check for collateral damage. i'm unsung out. he's not met in the beginning. i was counting the seconds at the time delay. but then when everything was in motion, it was just that was a sofa implosion. that was just ah, that was brilliant. yet. there was a moment of shock because the right block remained standing for

a very long time. but the additional explosive charge that was meant to fold it, gave it to its final impulse. the guns entrepreneur was i'm fine with all the tension has melted away. we just overjoyed that everything worked out the way we planned it over weeks and months to get all that work has paid off. yeah, the tide come on. well, congratulations, your voice for nothing broke except the building of the house. big ones go take a look with the white giant collapsed as planned and didn't cause any collateral damage or rica mattress and

her young team of engineers could not have wished for. a better start. martin hope for can safely hand over his company. and when the rubble has been cleared, a green park will replace the white giant. ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ah, a sex drugs and rock and roll a

breaking it's heavy. the rolling stones, the most successful, valuable time, it would be, are you $21.00 or 30 minutes to w. o. d w. this award winning offer is available worldwide in german has never been simpler. german to go will you become a criminal? mm franklin mayo already know who's with hackers and paralyzed me tighter societies. computers that oh sure you and governments that go crazy for your data. we explain how these technologies work,
