we're aggressively pursuing the dolphins and have launched an investigation or wanting to double your news line from berlin. dock film is next, presenting a look and how the discovery of explosives has helped shape humanity. forgot. there is more news and analysis around the clock on our website that is d w dot com. and you can of course, find us on all the majors, social media platforms, our handle there is at steadily news. at the next top of the our terry martin will be with you. i'm nicole really thank you so much for a company with an architect, jacqueline, or not at all women in architecture. why are this so invisible to the larger public? we decided to ask them versus, what is the poetry the secret of a house shattering good glass ceiling?

women in architecture starts april 20th on d. w. i. 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 swill 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 gemini, this is the white giant, a rundown apartment block from the 1970s. ready ready ready ready ready the city council wants to have it demolished. ready 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 6 flo will rica, motus is afraid of heights and doesn't enjoy riding the elevator. but martin

hopeful is having fun. if someone from now you can see that we're above the tree. tony with the 20th floor is a great book. ours is once you get a magnificent you across this industrial landscape, with joe montes is glad they only need to go up to the 6th floor. that work has civil ready started to weaken parts of the wools. this will make it easier to bring down the white giant may 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. and can, you can imagine it's like a tree when i'm home. remember to follow tree honey to cut out of which is how and that's exactly what we'll do here. hang tight, blast out a which i forgot. so this is the high rise was, will blast out of which 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 off to 4 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. decisions with ulcers. 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 that 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 stores 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 politically 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 alum 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 that 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 impact. there were many serious accidents. so guerrero 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 1860 for his brother, a male, and for others died in an explosion in the laboratory. legend hazards nobel finally finds a solution by chance. while in transport nitroglycerine leaks into a cushioning layer of grated diatoms. the resulting mushy substance is safe to handle. dynamite is invented, was a theme on painting. our systems don't have a few words. you contact my them with the lighter, we ok,

that wouldn't work because the kinetic energy of the lighter wouldn't be enough. acute images are explosive to the discretion of michigan. mean it's you that makes them very slave. the so guns we don't ignite with firma, lena? it's you but with pressure midst chemistry and again, it's on a mac 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 martin hot 1st company in east, in germany rica, motus, and her boss have returned from the white giant induced book 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, good. martin hope fir pause over the demolition plan which still needs the approval from a structural engineer from dr. mill's to just confirm the structural stability. suffering great assistance. zach was a household best boy. yeah, this project was a huge challenge that we need to factor in a bunch of things all at once. these are starting with the crammed conditions. i my, the blood fired msm that we only have limited space available off of her gone to the right of the white giant is an underground parking lot that must remain intact in front. is the street up 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 charges must not interfere with each other. additionally, the left block must also be folded, otherwise it would be too long for the gap. because initial pessimistic doesn't, we're not pessimists for the months. we're always optimistic during the planning. oh, but you also have to keep your eyes open for problems on can you simply cannot leave things to chance for during demolition, which we need to discuss everything in advance understand and we're thinking through voice thing. then we're able to bring down the building safely to spell out . 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 mat in hope for work quickly. the explosive stored here contain night traits which causes headaches and they still have a 4 and a half hour drive to deuce burg 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, bobbers bags, film studios, light. oh, some things 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 to an all season song that 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 lodge upon a metal low this door life a thick. she clenched with also use explosives under the car. quite a big lot less of a lot more to destroy anything or to create a shock way from the talk validate we had a bit of dust and then the viewer sees there's something happening will show a locally the patio. it 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 yeah,

it's been real dish langston were lot on form of item. so now i'm going to prepare the load will put onto the causal. i'm fixing the destination code in the form of a snail fingered and forming a snicker here off decides to exempt. so the force will then be distributed across the surface. i should forget 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 nominated new the la dogs, so the finished load that is going on the car to generate the blast wired cycles when the technicians mount a compressed air hose with a funnel. what, which way do you want to use 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 thin filters me quash playing nod on these micro charges. i'll take one out a so called cylinder 6. looks pretty inconspicuous that they can fire job. i quit talking about 300 milligrams, his one lectured selena. this cylinder sinks is used to create large molecules, shrinks on branches which day we have them in a range of sizes and in flashing in closing. saws in this is what our disks look like. classes are so this is the classic charge for body shop, sir. decrepit, power of this tiny thing also is enough to rupture a club back to. so she isn't to liquid than worked his way through a piece of clothing, though it's weak enough not to hurt any one. is alice rock and look 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 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 fly on me. want to see this route open, left standing 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. are. 2 wrong with what their attention. this will be very loud. i'm counting down 3 law to ah, one 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 in far from it. the technicians look at a video of the explosion. one shot was one hit. if it had jumped it behind,

absolutely. 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, guarantor santiago to mean the conf would be the blog if you execute to plaster. and as is the case here, the box to pick re duty of we have to break them up after through the stone crush. elsie or this is a mechanical device that costs much more than using explosive direct lender expose . e for direct m o t l. he been now has developed a method to perfect blasting enquiries. 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 aircraft 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. we welcome using the images still. he bene calculates a 3 d model of the blasting zone, no galleries, yen cell policy, but more of 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 daycare and where crocks 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 analogy. sort of prune you from pushy. the software calculates the exact distance between the bowl holes and the amount of explosives needed for each one. the operator on the drill rake 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 ready into spoke mat in hop fan and our re come out is worry about the white giant. 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 wall as we might have interfering. was it so by it was him come right michel joe? yes. like an improves the collapse does. this is off. that doesn't matter. for now, i only want to focus on the black will kind of will blame you. we don't have any problems with move in. 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 what,

when you hear the thirty's there, the 35 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 are demolished, the outer blocks could topple to soon and crash against each other. then debris would fly around uncontrollably. this must be avoided at all costs. that's why the blasting engineers and 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 explosive sky rectally 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'm of and because the other one must remain standing according to how we planned it and set one fuse, 2 tests for madison. miss martez. she'll take over i believe we start and go ahead and let's i 2nd plastic. no i oh awesome. second ball signal

ah, attentional. oh, so come back. 321 technician when okay, should bring this complete, accomplish my shot. now comes the moment. if tracy with tension is mounting at the potsdam bobbers bags, film studios, how toys sing, and tom taylor prepared the car. their client is already here. oh, to comes up to talk under all effect today. it's absolutely crucial. it all the effects we've planned love can happen at exactly the right time. 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 i and re talked until decline will say yes or not according to what's on yoda 9. luckily they found the fault in the air jack

yesterday. an engineer had changed something for another project and hadn't changed it back. thus for these charges who shoot out the doors crossing quickly prepares 6 black powder charges and installs them in the car. does captain schwartz per line that goes into the black powder? put the igniter in, then 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 go to it, but i need more power and i want to move steel dos. alba is called me up holiday 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. i saw on go ah, the pupil taken it would be helpful to find finding them klembara techniques were great. the client liked it. that's the important. thank you. after 4 seconds am good. we saw all our efforts produced. great, resolved yet, and then that's it. on done 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 yield play more takes over you see going from littler? we'll see you lucy. yes, it is fun to press the button holes a blast. as of course, the goal, we're working towards the left, but it's only a small part, so it only takes a 2nd when you put 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 stablish in a few 1st,

the work has prepared the bull holes. the sate quite cylinders a night trickle. i call 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 bow holes. ah, in a moment's 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 trunk 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 detonate the charge is by remote control from the top terrace of the quarry . ah well oh, $40000.00 tons of granite have come loose. that means 4 days of work for the excavators before del needs, new supplies. together with

a mining engineer, typically bene surveys the results. we got all got, lou hasn't done, jeff, come so the result of the blast is as expected, the movement of the rock masses was well under control. the chunks didn't fly further than twice the height of the demolition edge, which is how it should be to the edge is nice and straight on. the fragmentation is fairly homogenous, love are all in all a very good last illusion to go about most hon. jim, it's the triumph of technology over experience in the future. the corey operators will use t l. e been as software for every blast induced book the smoke has cleared martin hopper and oh, he come out his one to see which lasting technique worked better. first, the charges that were covered with sand canal.

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 is does was we are his off on will for years of you on. so this is what we were afraid of. that the wall that was supposed to be destroyed, hasn't crumbled from the top of the wall that was supposed to remain intact, has crack names on it, or how to your play that endangers the collapse process on the felt. it involves which load or the direction of the for con basil. possibly. now they checked the wall with the bull holes dresses. these are fully run this test destroyed the drilled wall and left the other one intact. within a positive wash that had wanted to be that way positively surprised why we wouldn't

have thought the wall behind it would remain so intact as well. but there are no crack sinners 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 on it. he's a he's a how so the issue that we were facing that these walls has now been solved as fit one think in duluth. yeah. now know how we have to adapt our technology and how to proceed. so it runs smoothly this mean sterling, 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 totally mid some altima, a very good colleague of mine had a fatal accident in his 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. channels on old cars have no air bags and certainly nor side air back. so i thought to myself, we should do something to the if a tree comes from this side or the alpha about from this protection order has an air bag comes out. does. was he obstinate 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

really did a tune, a kind of us and collected as to detect as a crash and then asked to reunite an in flight the correct air back or do i only need the airbag on the right side, do i need run the driver side of the side air box or a cushion, although there were all kinds of airbags that can be deployed. however, the life saver can also become a deadly danger. when was he forces us money? susie, you often see people putting their feet on the dashboard with all the large box. all them are well, far yoga. and of course everything that's placed back, it's ridiculously accelerated and bring it all your bonds would break really bad injuries. it's always, it's not worth putting your feet on that because it's cosy, jones? i guess what reason are you likely wouldn't survive established. so it's my suggestions are here willing to induce books. 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 fur reviews everything. he's nervous in the basement to engineers, a filling the last 4 holes. not yet. the challenge is don't, st. wouldn't get some detonating cord 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 idea. well, it's a unique number. every detonator has one open. when we've programmed each with

a certain destination tungsten site, with a delay of up to 30 seconds. excellent, then gus isn't by. that's unheard of and blasting technologies. i embody this as unique, so we're all excited for him or worry all. i don't know what to think at this. mike is moving. we'll do. so we'll see on trauma, electronic detonate is a more accurate spit. oh, so much more expensive than conventional ones. meanwhile, or rica motus is working on keeping track of everything. so that these colorful pitches of the result of a few night shift. i sat here every evening until 12 she needs to double check 1000 positions on her list. but hopefully now once to inspect the 6th floor with her, for ms. motus, please come here. fatty and i'll take care of everything else later. the sick slow will be blown out. there are hundreds of charges under the piles of sums. what

was as rupees with us? we don't like it shortly before. gross was the ignition system, again. conflict and i checked to see with all the detonated, 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 to school tomorrow morning. be different fagan, when that's when the excitement caused when counting i'll be fired out. ready 18 hours to go before the big blast. ready ready ready ready tom clia is now working on another project. he and his engineers, the trying to better protect pedestrians in the event. this struck by a car. and again they 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 i call manufacturers have developed to so called active heard sarah, small explosive challenges, shoot up the hood during a crash. that's it. perfect. the hood shut up in a hundreds of the 2nd routes is probably 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, like 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 cert. now with the insulin, these to be detected allows given the signal evaluated. and then an airbag, for example, has to be ignited or the hood has to come on. i need incredible speed, double and high pressure and force get only explosives can do that. unrestricted manufacturers now even develop external airbags to protect cars from other cars. so there's more to come. ready ready ready in display, the time has finally come. martine helps. i instructs the security guards. as one goes young,

it's possible that the building tips the wrong way that can happen when you and it can't be ruled out 100 percent of health. the 2nd dangerous that we generate vibration is offered firstly through the blast itself, but also through the collapse of the building shields. that's over $40000.00 tons of concrete that will come down the don't that will rattle the ground a bin. okay, you'll notice that note as well and something could fall from the building due to the vibration house. please think about your safety and it was a shot it. they haven't even laid the main ignition cable yet. the small move us. we have to do that. now with with michelle right now, i was huh. with her 2 years now, the 2 engineers from rica matches his team need to quickly run 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 caught up to

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 wouldn't make it down in time . if something goes wrong. charge the house line was most charged. how's line? obama? the water fountains captured the dust. ferguson missionary lera. okay. to fire crackers the settle beforehand to startle. pigeon said they don't get buried under the rubble.

massena hopes is last high. rise is history home. omar, let's take a look at what happened was swindle brazil. the engineers check for collateral damage among have is not met in the beginning. i was counting the seconds at the time delay i did 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 rights block remained standing for

a very long time. but the additional explosive charge that was meant to fold it, gave it its final impulse. the guns entrepreneur was fine with all the tension has melted away. yes, we just overjoyed that everything worked out the way we planned it over weeks and months to get all that work has paid off. yas untied command. raoul, congratulations your course. if nothing broke except the building that has 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 martine 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 ah, oh man, like freedom. cool, that's iranian women, not taking to the streets with my mom are risking their lives who are fighting against oppression who freedom the women in iran,
