netanyahu has announced he is putting a plan judicial over hold on hold full several weeks. the delay comes after months of mass protests and a general strike. as a yahoo said he made the decision to allow time to achieve a broad consensus. watching g w. news live from berlin up next, a documentary, looking at the history of explosive materials, allows leica and for me and the entire team here in berlin. thanks very much for your company. taking about ah, when you work as an architect, jacqueline, or not at all women in architecture, why are they so invisible to the larger public? we decided to ask them. the press is, what is the poetry the secret of a house?

shattering the glass ceiling, women in architecture starts april 20th on d. w. for 1002 years ago, the chinese made a discovery that changed the world explosives. for centuries they were used to kill and destroy. but explosives can do so much more. they save lives and take us to the stars they swell 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.

ah. ready ready ready ready deuce germany, this is the white giant, a rundown apartment block from the 1970s. ready ready ready ready the city council wants to have it demolished. ready ready martine hopeful will carry out this task. he's one of the most experienced to demolition experts in germany. it will be his last big project because he wants to hand over his company to only come motus. she's already started planning the demolition. now they want to inspect the 6 flow rica, motus is afraid of heights and doesn't enjoy riding the elevator. but martin

hopeful is having fun. oh, you can see that we're above the tree tones with the 20th floor is a great book. ours is when 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 work has civil ready started to weaken parts of the walls. this will make it easier to bring down the white giant. yeah. 29 of those. some with fell on him to some bull holes are still missing from home. let's see. it was magna, it's documented. and oh, good one. they want to blow up floors 6 and 7, and kind of you can imagine it's like a tree. i'm all remember to follow tree honey to cut out of which is how and that's exactly what we'll do here. and taylor blast out a widget for hall. so this is the high rise was, will blast out a wage,

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. missing misty. it is not as it were. kindergarten, children who, rec, other kids town. after 4 people often ask a decision, don't you have a problem, but you're always destroying. sto, shopping, blood, but know we're making room for something new. belgium that makes us happy, angel conditions, vultures, this demolition will shape or re come. marta says future korea because the industry is closely watching what's happening. induce book 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 cup through steel. with tremendous pressure, the explosive liquified, its copper casing, and drives the particles through the steel. this charge has forced to hold through 17 sick metal plates. the stores diaz was pan dormant, steel is or behave like a liquid. this being displaced by the explosion due to the high velocity of the particles emitted. it wasn't politically the liquid copper cut through steel like a knife hollow charge is that the best way to blow up stretches made of steel. in

the elaborate tree, the engineers can design explosives for almost any purpose. these gray blocks contain explosives mixed with alum minium powder. this creates a lot of pressure and is useful for blowing up buildings. a lot has happened since explosives were invented 1000 years ago. at that time, chinese researchers mixed so peter, sulphur and charcoal. the resulting black powder was 1st used for fireworks and later for warfare. black powder only detonated when its constrained. then it develops its explosive force and burns at 300 to 600 meters per 2nd. around 800 years later, the italian chemist, oscar neo. so guerrero invented nitroglycerin. it's an infernal liquid that already

contains all the ingredients for an explosive reaction. it's 4 times stronger than black powder, but very unstable and sensitive to impart. there were many serious accidents. sererow 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 1864, 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 painting. our systems don't have a few words. are you conduct my them with a lighter yeah. okay. that wouldn't work because the kinetic energy of the lighter

wouldn't be in norfolk feel to be meters, are explosive the discussion admission. i mean it's you what makes them very so 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 martine hop 1st company in eastern germany rica, mattress and her boss have returned from the white giant induce pork and her now finalizing their plans. meanwhile, an engineer is cutting destination cords. these red tubes are filled with an

explosive. they will need several 100 of these detonators for the white giant. they marked down each charge with its number and position in a large table. the bottom is that you're done. oh, okay, okay, good. martin hop fer pause over the demolition plan which still needs the approval from a structural engineer for from dr. mill's to just confirm the structural stability. sasa great, this isn't a sack, was a household best boy. yeah, this project was a huge challenge that we need to factor in a bunch of things all at once. these are starting with the crammed conditions. i might be black fired msm, but 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 out to,

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 because initial pessimistic doesn't. we're not pessimists, the months 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 deuce berg ahead of them there. they want to do blast tests on some walls of the white giant to make sure that the explosive charges really work potsdam, bobbers bags, film studios, light b, r a. something's not working. the car should have made a spectacular jump. but the mechanism got stuck, piled poor thing 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. log optically, the client is expected on said tomorrow, then to an all season song that will shoot out the doors and years old. another we have so called launch pods here with a counterpart in the door. when i put a load of black powder in the large pot, a metal low this door life of egg. she 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 visit. 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 a compressed air control to make the car jump. a total of 17 different effects will create a perfect illusion. while his colleagues work on the car pricing prepares the explosives in his workshop so yet been via dish langston will arden for

one item. so now i'm going to prepare the load the we'll put on the the coddle. i'm fixing the destination code in the form of a smile, fingered and forming a snicker here off decides to exempt so the force will then be distributed across the surface. i should for t. iron power pricing uses the same type of explosive code that will be used on the white giant. however, this code is my center, so nothing happens to the car. so i'm, it took me the lot on. so the finished load that's going under the car to generate the blast wireless cycles. when the technicians mount a compressed air hose with a funnel. what, which way do you want to do this? we'll create a large fire bowl inside the car. the funnel is loaded with pollen

because fine dust explodes spectacularly when ignited pricing is pressed for time because he needs to finish a project for another film. he's prepping bamboo poles with small explosive charges that will create bullitt hells. a thin filters 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 molecules, shrinks on branches, which day we have them in a range of sizes and in flashing and closing. saws in this is what our disks look like. classes are. so this is the classic charge for body shop, sir. declutter 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, want to see his routine conduct left standing blindness tires. meanwhile, pricings colleagues prepare the vehicle. tom teela puts the cardboard with the destination cord under the car. next to it, he places 2 small metal containers with gas cartridges. they'll create fireballs to cover the hydronic ram that makes the car jump. pricing

will trigger the effects by remote control. the engineers are putting in the doors, but they won't shoot them out until tomorrow when the customer arrives. because with explosives you never know if you get a 2nd chance. 2 i guess what the 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 was one hit. if it had jumped it behind,

absolutely. they only have until tomorrow morning to figure out the problem. to are in western france. this is one of the largest granite quarries in the country. here, engineers blast $6.00 to $7.00 times per month. the quarry provides hundreds of thousands of tons of rock and gravel for road and railway construction. the quality of the material is so good that it's used all over the country. 3 large 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 go doors and you'll demean the comp would read the blog if you execute to plaster. and as is the case here, the boxes to pick re duty will 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 expose. e for direct m o t l he been 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 air craft delivers images from various angles. it flies a predefined course and photographs the edge of the quarry.

after about 5 minutes, the job is done. thanks very much. we welcome. using the images steely bene calculates a 3 d model of the blasting zone or galleries, yen cell policy, but a more of the software is primarily used to design the blast. to put the data from the drone allows us to accurately calculate the geometry of the fracture. the software also calculates how the pressure will spread. thank you and where cracks are likely to form on the 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 energy. so to prune you from procedure, the software calculates the exact distance between the bo holes and the amount of explosives needed for each one. the operator on the drill rig receives the data on a usb stick. not only is the exact position importance,

but also the angle at which the holes drilled. the machine drives 17 meters deep into the granite. there needs to be 49 holes drilled by tomorrow morning. ready ready induce broke mat in hop fan and our re come out is worry about the white giant. ready they've already logged the detonators and challenges for the test blast into their system. now it's time to check the walls, cd or this was we might have interfering, was it so by it was m come right michel joe? yes, luck and influenced the collapse does, is it off that doesn't matter for now i only want to focus on the blah, blah, blah. here 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?

whoops. when you're here, the thirty's there, the $35.00 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, the demolished the outer blocks could toppled too soon and crashed against each other, then debris would fly around uncontrollably. this must be avoided at all costs. that's why the blasting engineers 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. so the building can collapse more easily. they're trying out 2 different methods in one spot. they place explosives directly

against the wall and then cover them with sand. when ignited, the charges should push against the sand and destroy the wall. in a 2nd location, they drill holes into the walls, which takes a long time. these holes. 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 said one, fuse 2 tests from madison mismatch. as you'll take over i'm sure we start and go ahead. let's i 2nd plastic. no i oh awesome. second boss signal

ah. attention, all posts all come back, 321 technician when okay, should bring on. there's a lot complete calmness my shot. now comes the moment if trace blue tension is mounting at the potsdam baba's bags. film studios, how toys sing, and tom t la prepared the car, their client is already here or to comes up to talk under other effect today. it's absolutely crucial. it all the effects we've planned love happen at exactly the right time. 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 they talked on to the client or say yes or not according to 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 bag das for these charges who shoot out the doors crossing quickly prepares 6 black powder challenges and installs them in the car. does captain schwartz the 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 body, it's that i need more power and i want to move steel dos. alpha is called me of holla and i fear sky. so i'll start typing it as a function and it's a tape. 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 light rolling your line. right. so i go, ah, the pool table to help find finding empire techniques were great of the client liked it. that's the important thing. after 4 seconds, even though we saw all our efforts produced, a great bizarre jip and then what'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. this 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 common some little wheels you may see yes, said spun to press the button holes, the blast. as of course, the gall, we're working towards the left, but it's only a small party, so it only takes a 2nd window, but a whole week of work goes into that one second focus i key. so our motivation is not just this moment. i'm old. we really have to take care of all the status in of yeah. first 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'd say moon gives the order to clean the area. ah, he will detonate the charge is by remote control from the top terrace of the quarry . ah, we owe $40000.00 tons of granite have come loose. that means 4 days of work for the excavators before thou need new supplies. together with

a mining engineer, typically bene surveys the results. we got all got lou as you don't, you have come. so the result of the blast is as expected to do, the movement of the rock masses was well on the 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 enough all in all a very good last lujan to go about. most of the 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 early 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. oh that the wall that was supposed to be destroyed, hasn't crumbled done with the wall that was supposed to remain intact as crack names. either how to your plot that endangers that collapse process. i'm defaulted involve showed all the direction of the force convo soon. possibly. now they checked the wall with the ball holes versus these are fully run co. this test destroyed the drilled wall and left the other one intact within a positive raj that had wanted to be that were positively surprised online. 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, if you look at it from the other side, there's nothing to say. i wonder why the material, blue eyed exactly in the area with the whole soil global on it. he's a he's a how so the issue that we were facing with these walls has now been solved on the thank 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, midsummer 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. shims of what the worst thing that can happen, channels on the home cause 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 hundredths of a 2nd. ah, the onboard computer in a modern car conducts a whole orchestra of airbags and was

ricky, did it, you know, 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, 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 us all your bonds would break really bad injuries. weird, so it's, it's not worth 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. 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 ideal. 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. he swinton bus isn't bought, that's unheard of and blasting technologies. i embody this as unique. so we're all excited for him or worried all i don't know what to think at this. my 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 that these colorful pitches of the result of a few not ships. i sat here every evening until 12 she needs to double check 1000 positions on her list. but hope for now wants to inspect the 6th floor with her. for ms. martinez, please come here. i count everything else, light up. the sick slow will be blown out. there are hundreds of charges under the piles of sums

what, what is a smokeless little mug shortly before engrossed with the ignition system, beginning 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 can all think 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're using explosives. the problem is there are lots of hot parts in the engine bay beneath the hood. in the event of a collision,

pedestrians can seriously injure their heads. that's why ca, manufacturers have developed to so called active heard ha, small explosive challenges, shoot up the hood during a crash. that's it. perfect. the hood shut up in a hundreds of the 2nd blue roots of possibly luther and now the how it is after mileage. this is the best position for a pedestrian to fall on to it and be protected from the hard components underneath the hood. doctor 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 he reached via, via mich brings awful, that right middle explosives and cars are important. so because we can generate extreme speeds to achieve a sir. now with the insulin, these to be detected allows given the signal evaluated. and then an airbag, for example, has to be ignited, or the hood has to come on. i need incredible speed or dial 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 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 at salvador, 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 movers we have to do that now with michelle right now like was oh with my with her 2 years now. i was one of the 2 engineers from rica mattresses team need to quickly run up to the 20th floor of a neighboring high rise and set up the master control. they chose this location because it offers the best overview the convert of can below the ignition 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 most charged to his line. obama, the wood 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 for his last high rise is history hall? ma ma. let's take a look at what happened was swindle bazillion. the engineer's cheque 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 its, its final impulse with the guns entrepreneurs with hon. 5 as well. the tension has melted away. we just overjoyed that everything worked out the way we planned it over weeks and months ago. all that work has paid off job tied comma roll, congratulation workforce 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 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 oh eco, india, how to clean and light a village all at once and we were to keep stalking lowered, escobar addressed to well. so this is a perfect as her mission in the, in the village of kanji, ron gall, generates electricity from waste, with
