and that's all for now on d. w. news, but stick with us because after the break, it's boom, which is our documentary looking at the science of explosives. remember, you can get all of your news around the clock on our website, which is d, w dot com. you can follow us on social media to a handle is at dw news, and you can also get more news on our breaking news app, which you can download from the app store. i'm jared radian, berlin, thanks so much for watching. have a great time with imagine how many portion of lunch are thrown out in the world. climate change to the very half the story. this is my plan, the way from just one week. how my wife can really go.

we still have time to go. i'm going with what with ah! 1000 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 with a 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 gemini, this is the white giant, a rundown apartment block from the 1970s. 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 germany. it will be his last big project because he wants to hand over his company to lee 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 bloomfield, in the 20th floor, is a great book out. once you get a magnificent you across this industrial mazda 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 wools. this will make it easier to bring down the white giant. yeah, the 29 of those. somewhere down there to some bo holes are still missing room. let's see. it was magnet. it's documented. and oh good was. they want to blow up floors 6 and 7 on can. you can imagine it's like a tree. i'm all remember to follow tree honey to cut out a which is how and that's exactly what we'll do here. hang tight, we're blast out a which i forgot. so this is the high rise or will blast out

a 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. 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. angel 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 cut 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 17th sick metal plates. the stores diaz was undamaged deal, so to 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 structures 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 $18.00. 60 for his brother, a male and for others died in an explosion in the laboratory. legend has at no bell, 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 also as a theme on kind of our systems don't have a few words where you contact my them with the lighter yorkie that wouldn't work

because the kinetic energy of the lighter wouldn't be in norfolk puter, greenacres are explosive to the discussion of michigan in and see what makes them very shy. the see guns, we don't ignite with firma lynette. it's you but with pressure mid chemistry in 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 east in germany will rico mattis and her boss have returned from the white giant induce pork 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 if you don't. oh. okay. okay, good. martin hoc fer pause over the demolition plan which still needs the approval from a structural engineer far from dr. mill's which is confirmed the structural stability, suffering great assistance. zach was a household us boy. this 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 street hope for and matters have developed a bold plan. they want to fold the middle blocks 1st 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. yes, in this person, miss anderson, we are not pessimist them on so we're always optimistic during the planning. oh, but you also have to keep your eyes open for problems and 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 wasting than we're able to bring down the building safely. the spot that 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 hop fer works quickly. the explosives stored here contain nitrate, which causes headaches. and they still have a 4 and a half hour drive to deuce burg ahead of them. they're. 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 with the aids 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. ultimately, the client is expected on said tomorrow, then to an all she's and song will shoot out the doors years old, not up. we have so called launch pods. here with the counterpart in the door, when i put a load of black powder in the launch pot and that was low this door like she clenched. i will also use explosives under the car, quite a big long list of the law 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. here it was. hidden in the trunk is the 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 the and via dish

langston were lot on former item. so now i'm going to prepare the load will put onto the coddle. i'm fixing the detonation cold in the form of a snail fingered and forming a snicker here off the slice to exam. 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 damn, it took me the lot. ok. so the finished load that is going on the car to generate the blast wireless cycles. will the technicians mount 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 thin filters me call sh playing nod on these micro charges. i'll take one out of so called cylinder 6. looks pretty inconspicuously all of the can find your bike. we're talking about 300 milligrams, his one except selina, this cylinder 6 is used to create large bullet. holes shrinks on branches, which day we have them in a range of sizes and in flashing and closing sourcing, this is what our disks looked like. classes. this is the classic charge for body shop, sir, because the power of this tiny thing also is enough to rupture a club back to, to washington, to liquid than worked his way through a piece of clothing. but it's weak enough,

not to hurt any want. is alice rock and look on how many 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 it out in a band. the guys go just as a yoke, and this is exactly what we wanted to harden gauze. we wanted to rip a large piece out of the bamboo and see materials in soft material. i her flying on me wanted to see this ripped open, that stand, lean blindness tires. meanwhile, pricing's colleagues prepare the vehicle. tom teela puts the cardboard with the destination code under the car. next to its 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 ah, that's what they're allowed attention. this will be very loud. i'm counting down 3, slide 2, 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 in bar from it. the technicians look at a video of the explosion. one shot was, or one hit it,

it jumped into 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 dumped 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. got dall santiago to mean the conf would read the blog if you execute to plaster. and as is the case here, the blocks to pick re duty of we have to break them up afterward through the stone crush. elsie, the old. this is a mechanical device that costs much more than using explosives, direct lender expose. e for director, mal t l. he by 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 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 t l he bene calculates a 3 d model of the blasting zone, no garage and cell pon seaborn. 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 day. based off of that, you said, you mean we can optimally place the draw hall's food so that the energy is distributed as evenly as possible. be shown danielle, he sort of prune you from placebo. the software calculates the exact distance between the bowl 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 induced berg mat in hop fat and already 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 m come right? michelle? 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 believe 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,

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 too 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,

reckless 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 you miss martez, you'll take over we start and go ahead and let's say 2nd plastic. no, i am almost 2nd ball signal ah,

attentional. oh, so come back, 321 technician when bringing this alone just complete. my problem is my side. 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, it comes up to talk under effect today. it's absolutely crucial. it's all the effects we've plan. love can happen at exactly the right tire tom. we want to win the client over and what's on demonstrate that this will be the scene that they'll get on the day of shooting. andre talked, anthony klein will say yes or not or couldn't. what's on yard annoying luckily,

they found the faults in the air. jack, yesterday, an engineer had changed something for another project and hadn't changed it back. thus for these charges will shoot out the doors. crossing quickly prepares 6 black powder challenges and installs them in the car. thus contin schwartzbar 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'd already 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 apologize for your style. 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 go, ah, the pure technical totally help with the find finding, including our techniques were great. the client liked it. that's the important. thank you. after 4 seconds, then we're done. we saw all our efforts produced. great, bizarre jip and then that'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 la wheels, you may see yes, it is fun to press the button holes, a blast. as of course, the goal we're working towards it, but it's only a small part of it only takes a 2nd, but a whole week of work goes into that one second focus i key so or 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 sick 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 on crush, the granite wall. ah

blasting and jenny as you blame, gives the orders 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 dell needs new supplies. together with

a mining engineer tele bernard surveys the results. we got all got, lou hasn't done yet. come so the results 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. 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 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 want to see which blasting technique. what better 1st, 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 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 on the field. it involve showed all the direction of the force convo soon. possibly. now they checked the wall with the bull holes because as these are fully run, got this test destroyed the drilled wall and left the other one intact within a positive raj that had 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 cool about on it. if you the house or 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 colleague from ace to leave me some old. i'm of 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. shims of what the worst thing that can happen. channels on the home, 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 over bottom from this protection order has an air bag comes out. does was he objects and kinda dust 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 hundreds of a 2nd. ah, the onboard computer in a modern car conducts a whole orchestra of airbags and was

really did it in a kind of as a collection has to detect if there's a crash and then asked to reunite an in flight the correct air back or do i only need the airbag on the right, so do i need one? the driver side of the side air box or a cushion. although there are all kinds of airbags that can be deployed. however, the life saver can also become a deadly danger. when was he forces us money? fuser you often see people putting their feet on the dashboard. what are the large box? all them are well, far, yoga. and it of course everything that replaced bag it's ridiculously accelerated, didn't bring it all your bones would break really bad. injuries via so it's, it's not was putting your feet on there because it's cosy, jones, obviously prison are you likely wouldn't survive as feminist. 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 stone 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 try and 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. tyson sites with a delay of up to 30 seconds. excellent. then bus is and by that's unheard of been blasting technologies. i embody this is unique. so we're all excited for him or worried or i don't know what to think at this. mike is, is move, it will be so we'll see on trauma. electronic detonate is a more accurate spit, also 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 the few not shifts. 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 montez, please come here. and i'll take out everything else later. the sick slow will be blown out. there are hundreds of charges under the piles of sums. what,

what is, is rupees with us? we don't want to shortly before gross with the ignition system again, 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, you know, tomorrow morning be different fiegel when that's when the excitement comes when consulting i'll be fired out. ready ready ready 18 hours to go before the big blast. ready 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 a so called active heard ha, ah, small explosive challenges, shoot up the hood during a crash. that's it. perfect. the hood shut up in a hundreds of the 2nd it's as far as a venue, 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 sucka 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 ricky 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 insulin, these to be detected allows given the signal evaluate it. and then an airbag, for example, has to be ignited, or the hood has to come on. i need incredible speed or dial and high pressure and force through can 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 display, the time has finally come. martine helps. i 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, i know 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 convent 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 the most george to his line. about them, off the water fountains captured the dust. ferguson missionary. 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 hall? ma. let's take a look at what happened was swindle bazillion. the engineer's check for collateral damage among have is not met in the beginning. i was counting the seconds the time delay i did then when everything was in motion it was just that was the so the implosion that was just odd. 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. with the guns entrepreneurs, with hon. 5 of us, 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, tied comma. congratulations, work boy. nothing broke except the building was 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. martin hop 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, e co, india, ah, the glacier is a melting climate change shows its true phase in the indian state of mashed l pradesh. so the solution,

reducing c o 2 through e buses will this was in 30 minutes on d w. where all that good to go beyond the obvious where as we take on the world 8 our i do all this. yeah. we're all about the stories that matter to you. whatever it takes, 5 police, my follow a deal. we are your is actually on fire made for mines. oh, how did she become at all for hitler's favorite director?

and how did any become a forgotten film pioneer? leaning, he finished and arnold funds between hitler and hollywood. in 1932, they set out into the icy wilderness of greenland to create a life threatening a film project that became a major milestone in their lives. love, seduction and power. ice cold passion starts october 8th on d, w. ah. this is the w news and these are our top stories. the u. s. space agency, nasa has deliberately crashed a spacecraft into an asteroids moon in the 1st ever planetary defense test. the aim was to alter the moon's.
