all in the final group stage game of the tournament. on monday chi harvard's fire in a beauty after 67 minutes to give germany a to new lead. but then luke shaw pulled one back from england. mason mounted the 2nd, and harry came converted to penalty. had responded with his 2nd of the night to snag appoint for his team and that's all for now. and d, w stick with our star after the brackets boom, which is our documentary looking at the science of explosives, this more d w dot com and dw news on social media. i'm tired read. thank keith. what with pleasure. gregory, this is the thoughts they will grey you. moon

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 they thrill us 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.

ready ready ready gemini, this is the white giant, a rundown apartment block from the 1970s. ready ready ready ready ready the city council wants to have it demolished. ready marteen hops, i 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 early cur mattis. 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 riding the elevator. but martin hopper

is having fun. how much? how you can see that we're above the tree tones, little than the 20th floor is a great book. ours is once you get a magnificent view across this industrial miles with marti's is glad they only need to go up to the 6th floor. their workers have already started to weaken parts of the walls. this will make it easier to bring down the white giant. the $29.00 of those somewhere fell on them to some bull holes are still missing. well, let's see. it was martina, it's documented. all good was they want to blow up floors 6 and 7 and can, you can imagine it's like a tree. i'm home. remember to follow tree honey to cut out of which is how and that's exactly what we'll do here. hang tight will blast out a, which i forgot. so this is the high rise was, will blast out

a wage. so it 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. this is misty, it is not as if we're kindergarten. children who rec, other kids towers. awful people often ask us an issue. don't you have a problem, but you're always destroying style shopping, blood, but know we're making room for something new. belgium that makes us happy angel editions. vultures. this demolition will shape or re come. marta says future korea because the industry is closely watching what's happening. induce book open 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 cup through steel. with tremendous pressure, the explosive liquified is its copper casing, and drives the particles through the steel. this charge has forced to whole through 17 sick metal plates. this dog deals with brand almond 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 putting 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 grey blocks contain explosives mixed with alum minium powder. this creates a lot of pressure and is useful for blowing up buildings. a lot has happened since explosives were invented 1000 years ago. at that time. chinese researchers mixed so peter, sulphur and charcoal. the resulting black powder was 1st used for fireworks and later for warfare. black powder only detonated when its constrained. then it develops its explosive force and burns that 300 to 600 meters per 2nd. around 800 years later, the italian chemist,

oscar neo. so guerrero invented nitroglycerin. it's an infernal liquid that already contains all the ingredients for an explosive reaction. it's 4 times stronger than black powder, but very unstable and sensitive to impact. there were many serious accidents. so guerrero himself was injured so badly that he stopped his research. but some one else continued. alfred nobel, he wanted to use nitroglycerin in mining, but he paid a high price in 1860 for his brother, a male and for others died in an explosion in the laboratory. legend 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, was, was it the mom painted lose? our systems don't have a few words where you conduct my them with

a lighter yorkie. 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 slave? the so guns we don't ignite with firma lynette. i gave it to you, but with pressure midst michelle 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 martini hot 1st company in eastern germany rica, mattress and her boss have returned from the white giant induced book and now finalizing their plans. meanwhile, an engineer is cutting destination cords. these red tubes are filled with an

explosive. they will need several 100 of these detonators for the white giant. they marked down each charge with its number and position in a large table. you've got a minute, you're done. oh, okay. okay. got it on martin hog fer pause over the demolition plan, which still needs the approval from a structural engineer for from dr. mill's to just confirm the structural stability suffer 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 off of her gone to the right of the white giant is an underground parking lot that must remain intact in front. is the street up for and matters have developed a bold plan. they want to fold the middle blocks 1st and then let the outer to tip

into the resulting gap. but 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. is initial pessimistic doesn't. we're not pessimists for the months. we're always optimistic during the planning. oh, but you also have to keep your eyes open for problems 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. 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 hop 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 some work 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, bobbers bags, film studios, lights, b, r o comics. 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. not optically, the client is expected on said tomorrow, then to an all season song that will shoot out the doors years old, not up. we have so called launch pods here when 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 . we also use explosives under the car. quite a big long list of the la don't want 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 been via the sh,

langston will arden forbidden. so now i'm going to prepare the load will put under the coddle. i'm fixing the detonation cold in the form of a smile, fingered and forming a snicker yourself so as to exam, so the force will then be distributed across the surface. like for tyran power pricing uses the same type of explosive chord that will be used on the white giant . however, this code is my center, so nothing happens to the car. so i'm, it took me the lot on. so the finished load that's going on the car to generate the blast wireless cycles, will the technicians mounts a compressed air hose with a funnel. what, which way do you want to use this? we'll create a large fire bowl inside the car. the funnel is loaded with pollen

because fine dust 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 creates bullitt hells. a central cliche, me course, playing nod on these micro charges. i'll take one out a so called cylinder 6. looks pretty inconspicuous that they can find you by. we're talking about $300.00 milligrams hazelynn lexa to linna. this cylinder sink is used to create large bullet holes shrinks on branches, which day we have them in a range of sizes and in, in flashing and closing sourcing. this is what our disks look like. classes are. so this is the classic charge for body shop, sir. decry the power of this tiny thing also is enough to rupture a club back to. so she isn't the liquid than worked his way through a piece of clothing, but 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 it out in a band. the guys go here. so the yoke and all this is exactly what we wanted to happen gauze we wanted to rip a large piece out of the bamboo and see materials in soft materialize. her flying on we want 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 it, he placed his 2 small metal containers with gas cartridges. they'll create fireballs to cover the hydronic ram that makes the car jump.

pricing will trigger the effects by remote control. the engineers are putting in the doors, but they won't shoot them out until tomorrow when the customer arrives. because with explosives you never know if you get a 2nd chance. are. 2 wrong with what they're attention. this will be very loud. i'm counting down 3 la too. 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 far from it. the technicians look at a video of the explosion. one shot, one hit. if it had jumped it behind. absolutely. they only have until tomorrow

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

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

after about 5 minutes, the job is done. thanks very much me welcome. using the images still, he bene calculates a 3 d model of the blasting zone. girlies yen cell punchy buttermore affair. the software is primarily used to design the plasticity of the data from the drone allows us to accurately calculate the geometry of the fracture. the software also calculates how the pressure will spread daycare and where crocks are likely to form on time. based off of that, you said, you mean we can optimally place the draw hall's food so that the energy is distributed as even the as possible. be shown the analogy sorta bruni form 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 induce book mat in hop fan and our re come out is worry about the white giant. they've already logged the detonators and challenges for the test blast into their system. now it's time to check the walls. to deal with this was we might have interfering, was it so by it was him come right michel joe. yes. like and influence the collapse does. this is off. that doesn't matter. for now. i only want to focus on the black . one kind of will blame you, we don't have any problems with marvin. and here we'll have to talk with the planner about what we can change and where are your test blasts in this area. now,

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 now conducting a test in the basement of the white giant. they have chosen walls that have to be destroyed before the blast. anyway, said the building can collapse more easily. they're trying out 2 different methods in one spot. they place explosives directly against

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

attention all posts all come back. 321 technician when there's a lot of complete calmness. 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 all the effects we've planned love can happen at exactly the right time. we want to win the client's hope and what's on demonstrate that this will be the scene. they'll get on the day of shooting. andre talked until decline will say yes or not according to what's on

yard annoying. luckily they found the faults in the air jagged yesterday. an engineer had changed something for another project and hadn't changed it bag does for these charges will shoot out the doors crossing quickly prepares 6 black powder charges and installs them in the car. does clinton schwartz per line that goes into the black powder? put the igniter in them, 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 slide 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, then we're done. we saw all our efforts produced great results. gibbon 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 play more take sofa. you see coming from the la, we'll see you lucy. yes, said spun to press the button holes, a blast. as of course the gall, we're working towards it, but it's only a small part. so it only takes a 2nd. 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 of yeah . 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 on crush the granite wall. ah,

blasting engineers, you'd say moon gives the order to clear the area ah. ready 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 to ask them 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 quarry operators will use t l. e been as software for every blast induce book the smoke has cleared. martin hopper and early kemati wants to see which lasting technique worked better. first, the charges that were covered with sand not

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. 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 done with the wall that was supposed to remain intact, has cracked. i am solid or how to your plot that endangers that collapsed process. i'm defaulted in vol. august. load all the direction of the 4 con basil. possibly. now they checked the wall with the bull holes versus these are fully ronco. this test destroyed the drilled wall and left the other one intact. b as in positive wash, that had one if it were positively surprised why we wouldn't have thought to the

wall behind. it would remain so in tag 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 when the material blew out exactly in the area with the whole soil global one of either he's the house or the issue that we were facing with these walls has now been solved on starting in duluth. yeah. now know how we have to adapt our technology and how to proceed. so it runs smoothly immigrants this means drilling even more holes. there's not much time left until the grand finale. about 300 kilometers further south in bavaria. tom clear developed safety systems for cars,

pseudo colleague from ace to league mid. some altima, a very good colleague of mine had a fatal accident in his vintage vehicle on a country road like this one road was well and he wrapped himself around the tree. seems to want the worst thing that can happen. child on old cars have no air bags and certainly nor side air back. so i thought to myself, we should do something to the if a tree comes from this side or the alpha above and there's protection order has an air bag comes out. does was he objects 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 500. so the 2nd ah, the onboard computer in a modern car conducts a whole orchestra of airbags there was

rekey, did it, you know, kind of as a collection has to detect. there's a crash and then asked to reunite and in flight the correct her back or do i only need the airbag on the right? sorry i need were on the driver's side is oh, 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 with all the large blocks . all them are well, far yoga and rid of course, everything that's placed back, it's ridiculously accelerated and bring it all your bonds would break really bad injuries. it's always, it's not worth putting your feet on there because it's cosy, jones, i guess what the fusion are, you likely wouldn't survive established. so it's my suggestion doesn't here, willing to induce books. the white giant is nearing it, sends excavators the piling mounds of earth around the building to catch flying

debris. the basement flows have been dug out, said the explosive charges can flattened, the high rise. martin hope for 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 and tried this? the idea, the crucial thing is the id label. 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 and by this, this is unique. so we're all excited for him or worry all, i don't know what to think at this point is, is move it will you will see on trauma electronic detonate is a more accurate spit. oh, so much more expensive than conventional once. meanwhile, or rica motus is working on keeping track of everything so that he's colorful pitches of the result of the few not ships. 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 sick floor with her or miss montez, please come here and i'll take count. everything else light up the sick slow will be blown out. there are hundreds of challenges under the piles of sums. what

was as rubies with us middle mother shortly before gross was the ignition system again and conflict and i checked to see with all the detonators hooked up to the main cold towards his guns. and then i'll go through it again with mister norbert when no one else is in the building, give it to stop without plans. double checking each floor again. oh, come now just to morrow morning. be different legal when that's when the excitement cost when consulting i'll be fired out. ready ready ready 18 hours to go before the big blast. ready ready ready ready tom clear is now working on another project. he in his engineers the trying to better protect pedestrians in the event. this struck by a car. and again they 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 herds law. small explosive challenges shoot up the hood during a crash. that's it. perfect. the hood shut up in a 100. so the 2nd this is probably new thought 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 an alternate song because we can generate extreme speeds to achieve a certain m worthy insulin. these to be detected allows given the signal evaluated . and then an airbag, for example, has to be ignited or the hood has to come, or i need incredible speed or dial and high pressure and force get only explosives can do that. unrestricted manufacturers now even develop external airbags to protect cars from other cars. so there's more to come. ready ready in this book, the time has finally come. martin 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 failed. the 2nd danger is that we generate vibrations or firstly through the blast itself, but also through the collapse of the building. schultz, that's over $40000.00 tons of concrete that will come down the don't that will rattle the ground a bin. okay, you'll notice that notice bell and something could fall from the building due to the vibration house. when please think about your safety and it was a shot it, they haven't even laid the main ignition cable yet. the small move 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 convent of can below the ignition court 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 was a most george. how's line? obama? the wood fountains captured the dust. ferguson missionary lera. okay. 2 fire crackers. the set off beforehand to startle. pigeon said they don't get buried under the rubble.

marcin hope says last high rise is history. hulma. mar, let's take a look at what happened was swindle bazillion. the engineer's check for collateral damage. i'm trying to 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 art. that was brilliant. and 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 gonzandi by noah's uncle 5 of us all the tension has melted away. we just overjoyed that everything worked out the way we planted over weeks and months together. all that work has paid off job tied, comma, congratulations, workforce. for 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. rica massey and her

young team of engineers could not have wished for a better start. martin hope for can safely hand over his company. and when the rubble has been cleared, a green park will replace the white giant. ready ready mm hm. ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ready ah, a pulse ah, the beginning of a story that moves us and takes us along for the ride. it's only about the perspective culture
