he made the decision to allow a time to achieve a roll of consensus. you're watching a dw news alive from berlin off next, a documentary looking at the history of explosive materials as a waste. this is more news and analysis on our website, t, w dot com and kick us social media accounts. we are asked to d. w news on instagram. on twitter. i'm log soccer from unity. 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 person, 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 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 swear less and make room for something new. millions of tons of rock a mind every day with explosives. without them a world would be very different.

ah. ready ready ready ready gemini, 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 germany. 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 re kemati. this 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, thompson we will be in the 20th floor, is a great book. ours is once you get a magnificent view across this industrial last visit, with joe montes is glad they only need to go up to the 6th floor that workers have already started to weaken parts of the wolves. this will make it easier to bring down the white giant. yeah. 29 of those. some with salmon. him to some bow holes are still missing home. let's see. was magna. it's documented . and oh, good was they want to blow up flows 6 and 7. and kind of you can imagine it's like a tree when i'm home. remember to follow tree honey to cut out of which is how in that's exactly what we'll do here in case we're 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 using misty it is not as if or kindergarten children who rec, other kids towers off to 4. people often ask a solution, don't you have a problem? was you're always destroying style shopping blocks. but know we're making room for something new about them that makes us happy. angel distance vultures. this demolition will shape or re come. 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. 321 was blasting engineers all over the world. use hollow challenges to cup through steel. with tremendous pressure, the explosive liquified, its 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 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. 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 or you contact my them with the lighter. we ok, that wouldn't work because the kinetic energy of the lighter wouldn't be in norfolk

puter, greenacres, are explosives need, especially initially, i mean it's you what makes them very slave. the so guns we don't take night with firma, lena jacob, it's you. but with pressure midst machine again. 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 martin hot says, company in eastern germany will rico mattis and her boss have returned from the white giant induced book and, 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 is that you're done. oh, 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, 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 might be black fired msm, but we only have limited space available to fall through. gone to the right of the white giant is an underground parking lot that must remain intact in front. is the street papa and mattis have developed a bold plan. they want to fold the middle blocks fast and then let the outer to tip

into the resulting gap. but 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. because initial pessimistic doesn't, we're not pessimists in a month. 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 voice thing. then we're able to bring down the building safely to spoke out . we go fields with 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 hop for work quickly. the explosive stored here

contain nitrate, which causes headaches. and they still have a 4 and a half hour drive to do some work 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. 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 yog. optically, the client is expected on said tomorrow, in tune all season song will shoot out the doors years old, not up. we have so called launch pod chair with a counterpart in the door when i put a load of black powder in the large pot, and that was low this door life, a thick clenched. we 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 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 yet been via the sh,

langston will arden for both items. so now i'm going to prepare the load will put onto the coddle. i'm fixing the detonation color in the form of a smile thing that and formula 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 let me turn the light on. so the finished load that is going on the car to generate the blast wired cycles. well, 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 create bullitt hells as infiltration. recall spring not on these micro charges. i'll take one out of so called cylinder 6. looks pretty inconspicuous that they can fire job. i quit talking about 300 milligrams, his lin lexa to linna. this cylinder sinks is used to create large bullet holes rings on punchers, which day we have them in a range of sizes. and in fashions in closing. saws in this is what our disks look like. classes. this is the classic chart for body shop, sher declutter power of this tiny thing. holes is enough to rupture a club back to to she isn't to liquid and worked his way through a piece of clothing, though it's weak enough not to hurt any one. is alice rock and look on her knee. months of her lesson. 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 can fly on me. wanted to see this route. i could stand lean 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 of 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. 2 i guess what they're allowed 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 in that wasn't enough in bar from it. the technicians looked at a video of the explosion. one shot was one hit. if it had jumped it to be fine, 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 guarantors and you'll demean the conf would read the blog if you execute a blossom. and as is the case here, the boxes to pick re duty of 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 exclusive director mal t. l. he by 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 is 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. we welcome using the images still. he bene calculates a 3 d model of the blasting zone. now galleries, yen cell policy, barrymore affair, the software is primarily used to design the blast. the, the, 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 said you, we can optimally placed the drill holes so that the energy is distributed as even the as possible, be shown the energy. so pruning from placebo the software calculates the exact distance between the bo 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 ready induce berg mat in hot fire and our re come out is worry about the white giant. they've already logged to 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 m come right michelle? yes. welcome to influence. the collapse does, is it off that doesn't matter for now? i only want to focus on the black one kind of will leave 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're here, the thirty's there,

the $35.00 would from wallet 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 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 are now conducting a test in the basement of the white giant. they have chosen walls that have to be destroyed before the blast anyway. so 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 are 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 said one fuse 2 tests for madison you miss martin, you'll take over i believe we start and go ahead. let say 2nd classic. no, i am austin 2nd ball signal ah. attention,

all posts all come back, 321 technician when complete, my problem is my shot. now comes the moment. if trace with tension is mounting at the potsdam baba's bags. film studios, how toy sing, and tom taylor prepared the car. their client is already here or to comes up to talk under all effect today. it's absolutely crucial. it's all the effects we've plan. 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. i and we talked on 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 back. does for these charges who shoot out the doors crossing quickly prepares 6 black powder charges and installs them in the car. does continued schwartz per line that goes into the black powder, put the igniter in, then close it. so that's a finish charge. so it does really it's, i can kill ready as a lot of power even like this. you bought 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 pool table to help find finding 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

with 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 to come in so little? we'll see you lucy. yes, it is fun to press the button was a blast. as of course, the gall, we're working towards the left, but it's only a small party, so it only takes a 2nd. 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 feel. first, 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. in m, 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. ready 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 del needs, new supplies. together with a mining engineer, typically bene surveys the results we got dollar wasn't done,

just come so the results of the blast is as expected to do, 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. the edge is nice and straight on the fragmentation is fairly homogenous, love are all in all a very good last illusion because most of them would you it's the triumph of technology over experience in the future, the quarry operators will use t l. e been as software for every blast induce 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 sams 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 this does was we are is off on will for years of you are so this is what we were afraid of. that the wall that was supposed to be destroyed hasn't crumbled from it. but the wall that was supposed to remain intact has crack names either. how to your plot that endangers that collapse. process undefended involve showed all the direction of the force con basil, possibly. now they checked the wall with the ball holes versus these are fully ronco. this test destroyed the drilled wall and left the other one intact for years in a positive lodge to have lunch with were positively surprised why we wouldn't have thought that the wall behind it would remain so intact as well. but 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 on it. he's a he's a how so the issue that we were facing with these walls has now been solved on thank in duluth. yeah. now know how we have to adapt our technology and how to proceed. so it runs smoothly 4 pm. 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 collier from ace to league mid. some altima,

a very good colleague of mine had a fatal accident to this vintage vehicle on a country road like this one road was well and he wrapped himself around the tree. shims, it was the worst thing that can happen, child is on hold, 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 or the other bottom from this protection order, has an airbag comes out, does, was he options and 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 then, asteroid night, and in flight the correct air back. so i only need the airbag on the right, so i need one on the driver's side as well. 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 money. susie, you often see people putting their feet on the dashboard. what are they? large pothole them. are well, far yoga and rid of course, everything that's placed back, it's ridiculously accelerated, didn't bring all your bands would break really bad injuries. it's always, it's not worth putting your feet on that because it's cozy. jones, i guess what the prisoner likely wouldn't survive established. so it's my suggestion, does a here believe 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 bull holes. not yet. the challenge is don't, st. would 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 entreating 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 tungsten site, with a delay of up to 30 seconds, excellent,

then bus is and 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 point is, is move, it will do. so we'll see on trauma, electronic detonate is a more accurate spit, also much more expensive than conventional ones. meanwhile, or re kemati. this is working on keeping track of everything so that he's 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. what is not as please come here, fanny, i'll take count everything else, light up the sick slow will be blown out. there are hundreds of charges under the piles of sums.

what was as rupees with us middle market shortly before gross with the ignition system. again, conflict and i checked to see with all the detonators hooked up to the main core doors of guns and then i'll 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 to morrow morning. be different vehicle when that's when the excitement cost. when consulting colby fired out. ready ready ready 18 hours to go before the big blast. 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 hot 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 heard ha, small explosive challenges, shoot up the hood during a crash. that's it. perfect. the hood shut up in a 100, so the 2nd blue roots is possibly 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 a hoodie 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 and vicki vile via mich brings off of the drive, middle explosives and cars are important. so because we can generate extreme speeds to achieve certain them, with the incident, needs to be detected allows give it the signal evaluated. and then an airbag, for example, has to be ignited or the hood has to come, or i need incredible speed or dial and high pressure in 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 this book, 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 danger is that we generate vibrations or firstly through the blast itself, but also through the collapse of the building shields. that's over 40000 tons of concrete that will come down the don't that will rattle the ground a been a good. 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. this moment was we have to do that now with with michelle right now. was huh. with my, with her 2 years now, the 2 engineers from rica matches his team need to quickly run up to the 20th floor . if 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 her fear

of heights, motus would also like to be up that to press the button. but hope for once there 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 with the most charged hows line. obama. the water fountains captured the dust. ferguson, mission, leisure. okay. to fire crackers, the settle beforehand to startle. pigeon said they don't get buried under the rubble

machine hopes his 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 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 gonzalez by noah's uncle, 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 ago. all that work has paid off. yas untied comma congratulations, workforce for nothing broke except the building that was big. want to 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 rebel has been cleared, a green park will replace the white giant. ready ready mm hm. ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ah, the beginning of a story that moves us and takes us along for the ride. it's all about to perspective. culture information this is d w. news and more. d w. made for
