portions of damage is unavoidable because a hurricane that comes out with such a force. what cause damage, but we're trying our best with global seaman, u. s. president joe biden has declared a state of emergency in florida and some, 2 and a half 1000000 people are under evacuation orders. the government has prepared huge amounts of fuel, water meals and emergency personnel to try and mitigate. what looks likely to be a full blown disaster? stay tuned for our documentary about the science behind explosions. i've been for solon, terry martin will have your use of mixed ah, how did she become at off hitler's favorite director? and how did he become a forgotten, sil pioneer, leniently finished, and arnold funk a documentary about love seduction,

and power ice cold passion starts october 8th 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 she 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 wealth would be very different.

ah. ready ready ready do stud 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 only come motus. she's already started planning the demolition. now they want to inspect the 6th floor rica, motus is afraid of heights and doesn't enjoy writing the elevator. but martin

hopeful is having fun. oh, you can see that we're above the tree tones little than the 20th floor is great because once you get a magnificent view across this industrial mask with motus is glad they only need to go up to the 6th floor. the workers have already started to weaken parts of the walls. this will make it easier to bring down the white giant the 29 of those, some with salmon, him to some bow holes are still missing home. let's see. it was magna, 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 was 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 go forth. people often ask oscillation, don't you have a problem, but you're always destroying style shopping blocks that know we're making room for something new about them. that makes us happy as well. conditions, revulsion, this demolition will shape or rica. marta says future korea because the industry is closely watching what's happening into spoke children house in germany. deep in the forest lies a well hidden research site. here scientists develop explosives for military and civilian purposes. a so called hollow charge

designates in a bunker with enormous force 321. looking to go 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 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 wasn't particularly 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 $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 team on kind of our systems don't have a few words where you contact my them with the lighter. yeah. okay. that wouldn't

work because the kinetic energy of the lighter wouldn't be enough. people to be meters are explosive, the discussion admission. i mean it's you. what makes them very shy? the see guns, we don't ignite with firma lynette. it's you. but with pressure midst amateur 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 rica, motus, 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, no, you don't. okay? oh, okay, 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 suffer great. zach was a household a home 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 bless, fired msm that we only have limited space available off of her go 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 challenges must not interfere with each other. additionally, the left block must also be folded, otherwise it would be too long for the gap. there. sidney pessimistic doesn't, we're not pessimists for the month of 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 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 do, spoke ahead of them there. they want to do blast tests on some walls of the white giant to make sure that the explosive charge is really work. pud stumbles bags. film studios. yeah, it's me mary lou on it. but something's not working. the car should have made a spectacular jump. but the mechanism got stuck power placing is a pyro technician who worked on the special effects in major production, such as game of thrones and die hard

left. so special effects are the go to company for a big bang. to day the team is working on a top secret production in which a car is supposed to explode dog optically, the client is expected on set to morrow, 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 launch pot and that was low this door like clenched. we also use explosives under the car. quite a big long list of the law. i don't want to destroy anything or to create a shock way from the talked 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 been via dish

functional art on formal item. so now i'm going to prepare the load that will put onto the causal. i'm fixing the detonation called 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 for tyrone 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 dominated me the lot on. so the finished load that is going under the car to generate the blast wireless sightings when the technicians mount a compressed air hose with a funnel. what, which way do you want it? this will create a large fire bowl inside the car. the funnel is loaded with pollen

because fine dust explode 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 bullet hells a central push me quash playing not on these micro charges. i'll take one out a so called cylinder 6. looks pretty inconspicuous of the can fire job. i quit talking about 300 milligrams. his one lectured selena this cylinder sinks is used to create large bullet holes rings on branches which day we have them in a range of sizes. and in, in washington closing, saws in this is what our disks look like. classes are. so this is the classic charge for body shop, sir. decry the power of this tiny thing also is enough to rupture a club back to. so she isn't to liquid 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 all this is exactly what we wanted to harden goals. we wanted to rip a large piece out of the bamboo. what and she materials in soft material, i her flying on me wanted to see this root canal that stands green 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 i guess what the 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. the bar from it. the technicians look at a video of the explosion. one shot was one hit. it,

it jumped out of your mind. 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 lasting engineers into our have decided to try out a new approach to increase efficiency. guarantor santiago, mean the comp 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 afterward through the stone crush elsie doors. this is a mechanical device that costs much more than using explosives, direct lender expose. e for direct m o 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 still. he bene calculates a 3 d model of the blasting zone, auxiliaries, yen cell policy, but a 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 drill holes so that the energy is distributed evenly as possible. be shown the analogy sort of prune you from procedure. 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. is it off that doesn't matter for now i only want to focus on the black 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, 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 demolished, the outer blocks could toppled 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 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 are then loaded with explosives. vista it's important to see what happens when we demolish one wall line of on because the other one must remain standing according to how we planned it except one fuse 2 tests for madison. miss martez, she'll take over i believe we start and go ahead. and let's say 2nd plastic. no, i aust, 2nd ball signal ah. attention. all posts all come back.

321 technician when you bring this is 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 toys 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 and happen at exactly the right time tom. we want to win the client's hove 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, i 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. thus for these charges who shoot out the doors crossing quickly prepares 6 black powder challenges and installs them in the car. thus, clinton schwartz the 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'm to 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 is called me a power 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 slide on go ah. the pool table to help find finding empire techniques were great of the client liked it. that's the important. thank you. after 4 seconds am good, we saw all our efforts produced great results, jim 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 you'd play more takes over you to come in some little wheels. you may see yes, it is fun to press the button holes, the blast. as of course, the goal we're working towards it, but it's only a small part of it only takes a 2nd when you 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 sate quite cylinders a night tra glycol, a common explosive inquiries. such a charge can crumble a massive concrete wool. but here they only service boosters to ignite the liquid explosive that's now being filled into the bo huls. ah, in am i meant t as he been now, we'll find out whether his software is superior to the experience of the local demolition experts. the explosive mixture on the truck is a rather slow burning explosive. that's because the engineers want to generate a uniformly high pressure in the rock, which will create many cracks and crush the granite wall. ah,

blasting and jenny as you'd say moon gives the order to clean the area ah. ready he will designate the charge is by remote control from the top terrace of the quarry. ah, 2 o. 240000 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 tele bernard surveys the results. we got all yellow has been done . jeff, 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 to the edge is nice and straight to the 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 induced book the smoke has cleared martin hopper and early come out his one to see which blasting technique worked better. first, the charges that were covered with sand canal,

exactly the wrong way round the explosive charities 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. oh so does this does was we are resolved on whoa for years of you on. so this is what we were afraid of. it that the wall that was supposed to be destroyed hasn't crumbled them with about the wall that was supposed to remain intact, has cracked names either how to your plot that endangers that collapsed process on the felt it involve showed all the direction of the for con, basil possibly now they checked the wall with the bow holes glasses. these are from the one key on this test, destroyed the drilled wall and left the other one intact. v as in positive watched i had lunch with them, were positively surprised why we wouldn't have thought the wall behind it would

remain so instead of them. 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 a does. he's a he's a how so the issue that we were facing with these walls has now been solved on starting in duluth. yeah. now know how we have to adapt our technology and how to proceed. so it runs smoothly, probably intricate, 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 colleagues from ace. thirdly, mid some owe them 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 the home cars 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 elbow bomb 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 hundredths of a 2nd. ah, the onboard computer in a modern car conducts a whole orchestra of airbags and was

really did it, you know, kind of as a correction, has to detect as a crash and then asked to reunite and in flight the correct air back. so i only need the airbag on the right, sorry. do i need run the drivers side of the side air box or 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 they? large pothole them. are well, far yoga. and did of course everything that replaced bank, it's ridiculously accelerated, didn't bring it all your bonds would break really bad injuries. via so it's, it's not was putting your feet on there because it's cosy. jones, obviously presumably 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 set 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 detonated those and tried this. the idea, the crucial thing is the idea no more. 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 been 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 you will 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 wants to inspect the 6th floor with her for ms. mottos, please come here 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 summed what's

what is as rubies with us, we don't like it shortly before gross would 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 him. tomorrow morning. be different fiegel when that's when the excitement cause when consulting i'll be fired out. ready ready ready 18 hours to go before the big blast. ready ready ready 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're using explosives. the problem is there are lots of hard parts in the engine bay beneath the hood. in the event of a collision,

pedestrians can seriously injure their heads. that's why i call manufacturers have developed a so called active heard sod. 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 let'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 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 to hold a drive middle explosives in cars or an alternate. so because we can generate extreme speeds to achieve a certain amount would insulin, these to be detected allows given the signal evaluated. and then an airbag freaks all day has to be ignited, or the hood has to come. i need incredible speed to deborah and high pressure and force get only explosives can do that. under sprinkler manufacturers now, even develop external airbags to protect cars from other cars. so there's more to come. ready ready in display, the time has finally come. martin 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 and it was your head, they haven't even laid the main ignition cable yet. this bomb it was. we have to do that now with with michelle right now like was oh, with my with her 2 years now. the 2 engineers from rica mattresses 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 with conrad 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 with the most charged house line. obama, 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.

marcin hope says last high rise is history hall? ma ma. let's take a look at what happened. a swindle bazillion. the engineer's check for collateral damage. i'm unsung out. he's not met in the beginning. i was counting the seconds at the time delay. but then when everything was in motion, it was just that was a sofa implosion. that was just ah, that was brilliant. yet, there was a moment of shock because the 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 with i'm go file as well. the tension has melted away. you've yes, we just overjoyed that everything worked out the way we planned it over weeks and months ago. all that work has paid off. got the ties, come up. congratulations looked voice for 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. 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 ready ah, patriotism on the right. how does the nation define itself? a question of the lost in the former soviet days. the war in ukraine has given us a new urgency, a report questions,

what's behind the bass all over national identity. close up in 30 minutes on d. w to own or not to own. what about a sharing economy instead? a change in thinking is changing the economy to create something new the economics magazine made in germany 90 minutes on d w. good. hello guys. this is the 77 percent the platform with issues and share ideas. you know, all these channels. we are not afraid to talk to young people clearly have the

solution. good future loans to the 77 percent every weekend on d w with ah ah, ah, this is dw news coming to live from berlin, condemnation and sanctions. as russia declares victory in its so called referendums, moscow installed officials claim up to 99 percent of voters across several ukrainian regions. want to join russia. ukraine and its western allies reject the results and pledge.
