I never heard that shape of trenches is to dissipate shock wave. I was taught that it is to a) stop shrapnel and to limit visibility/cut short line of aim down the trench in case enemy forces manage to invade it.

This is the correct answer

About the small scale trench thing, how is everyone carrying on about margin of error? The waves are produced mechanically and perfectly consistent, removing any possible errors. Consistency equals accuracy, and i think they nailed it.

[@cobusvanderlinde6871]

I imagine that there's a lot more you could do to mitigate shockwave propagation through a trench. So have the trench step back and forth (at the end of the test trench there would be another two turns to get the trench back in line with the original line of the trench... BUT, have the trench always overshoot the passageway that connects the forward and rearward trenches. That way the blast can partially continue forward into a dead end, and the portion of the blast that travels down the branch to the other line would also split left and right into the dead end here as well.

[@stanislavczebinski994]

The main difference between an artillery gun and a mortar is the firing angle - not the projectile weight. Some guns are able to work in both roles due to a big angle range. A mortar has usually a shorter barrel than an artillery gun. Back in WW1 - some really huge mortars were used. The German 42cm Gamma-Gerät shot heavy shells of 1160kg.

[@Manuelslayor]

​@stanislavczebinski994 Artilery is generally heavier than mortars. 105mm is considered light artillery 155 is standard and 180+ is heavy. Light mortars are 50mm standard is 80 and heavy is 120. Though it is true that some of the heaviest ever used where mortars

[@andybrown4284]

Airbags aren't designed to hold the gas inside the way a balloon does, the safety comes from the controlled deflation in a similar way to the crashbags stunt performers use for jumping off buildings safely. Trenches should really have been twice as long with the explosion in the middle as an explosion at one end is directing the blast down the same way, skews the numbers quite a lot when comparing to the surface control.

[@MajorWhite]

There is something I have not seen them test via trenching. When you carve out tunnel shelters in a snow bed, you usually want to make sure that the breeze does not funnel in to your room. What you would do to counter that, is make something like a T junction, where at the end of a sharp corner you just continue digging 2-4 feet further past the next turn, to force the pressure from the breeze to just stop and push back on itself. If that were to be tested with explosives, I can for certain expect a drastic amount of change in the pressure wave going through the whole thing.

[@borntoclimb7116]

[@allanshpeley4284]

The square vs rounded trench data they obtained from the large scale experiments was almost identical - probably within the margin of error.

[@eqe2e23e]

48:16 not just that, but also if the first measurement is at the same distance and before the first curve in all cases the dampening effect should also be about the same in all cases, but was significantly stronger (76 vs 60 vs just 39) in the rounded trench so the end result of rounded trench is dampened more (from 76 to 8 is by 68) than at square (from 60 to 7 is by 53).

[@MrJinxmaster1]

Problem is that by not having walls on the rounded corners more of the force would have gone into the soft earth than in the right angle trench. They shouldn't have put those walls in if one test was going to lack them. Minimise variables.

[@allanshpeley4284]

@@MrJinxmaster1 Agreed. That crossed my mind as well. You'd think they would have learned these lessons by this far into the show.

[@d4slaimless]

That's the problem of doing test only 1 time. No statistics. And the blasts didn't have the same energy at the start position. If anything trench with rounded corners had higher starting pressure, but finished at almost the same number as trench with sharp corners. They should have declared those results inconsistent due to different initial conditions. But then it would be rather unsatisfying conclusion for the show. So they went with rather dubious one. I think it was possible to make a small scale test with explosives making 3 runs of each type of trench. But it is not as spectacular as a full scale blast. Anyway, it was a show, not a science research. Pretty sure some articles on the matter can be found.

[@jarrodbright5231]

@@d4slaimless I'd say they squibbed the conclusion completely. Should have said both provide protection but the square corner ones provide slightly better protection so half the myth is confirmed and half the myth is busted.

[@rwandaforever6744]

I am a bit confused by the numbers in both experiments. 1. Trenches Open air explosion: 39-12-7-5 Straight trench: 397-65-38-21 Sharp Corner Trench: 60-19-12-7 Round Corner Trench: 76-21-13-8 While the myth seems plausible, I do not get the enormous difference at 20ft. That is before the first ned is reached, meaning at that point all trenches were identical. And should have given the same values. There is no reason why the straight trench should give 5-7 times more pressure at 20ft than the other two. This is fishy. The difference between round and sharp corners is small. This could easily be explained by various variables like how the explosive was packaged, how it was placed, how it burned, etc. If it was angled slightly downward, this could make all the difference. And again, at 20ft. there should be no difference at all, yet there is. And I did not get the reason why they shored it up. You can cut a more precise corner with just earth. Trenches in WW1 rarely were shored up, because they were temporary. Only in long-term trench warfare like Verdun and others did it make sense to put time and effort in shoring up. And, yeah, with n=1 you can't really say anything. 2. Balloons The test rig did not work correctly. The drop distance of the weight was different, because the height of the balloons differed. Thus the better dog-balloon cushion lost only because the weight dropped nearly double the distance before contact with the balloons. I am not really impressed with this episode.

[@ChilledfishStick]

Very much agree. The balloon test was even worse than you describe, because a clown isn't in the shape of a circle, and he wouldn't have been launched into a cylinder containing both himself and the balloons.

Tbh the ballon test is pretty useless, the reason an airbag works is because its a fixed ballon. During the car crash the "passenger" pushed the ballons out of the way. Which will always be the case for unfixed ballons, it will always just move out of the way instead of absorbing the energy. Now the ballon crusher was also a bad rig, since the baloons were confined to the tube forcing them to actually absorb the load, which wouldn't have hapenned in the actual car, once again they would have simply been pushed out of the way. And the last car also wasnt a perfect comparison since its the first car completely filled with baloons so the baloons couldnt move outof the way. (They basically controlled for it) the last tests with ballons bunched together is fairer since its pretty obvious it cant be compared to the starting test

[@EL-SKiN]

Can someone explain why the two angled trenches produced significantly lower numbers on the first 10ft measurement than the straight line trench. The 10ft measurements were all taken before any corners. I can understand why the trench amplifies the blast wave. I would've expected that to be the case. and I can understand why standing at the far end of the sharp angled trench would be the safer option. Again, its what I was expecting But I would've expected the first set of measurements from the blasts in the trenches to be around the same point. They were closer to the above ground test than the straight line though.

[@kikixchannel]

This is just an assumption, but maybe the corner right after the measuring device had some of the early wave bounce back and mitigate the following pressure surge. In the straight one, the wave had a clear, funneled path all the way to the point where it basically was irrelevant, so the the full, magnified brunt of the blast was able to pass on without interference from itself. Though quite frankly, not knowing the physics behind explosions well enough, I would still expect it being more of a case of accidentally using too much power in the straight one...

[@carneeki]

I wouldn't be surprised if they did the same experiment several times for each trench to get a spread of varying measurements. The problem with TV is that rigorous stats does not make for great viewing, and they probably had a budget and deadlines to meet so it's just not worth the extra digging and blowing up and filling back in again. Also weren't the walls different? Exposed dirt for one of them. Perhaps the soft surface or rough texture did more to absorb than smooth plywood? The explosive loads may not have been accurately and precisely matched either. Hence the need for more rigour in testing, but that's boring compared to boom time.

[@scottll]

Got to be an error with the sensor. The reading was wildly different.

If the driver clown with a seatbelt on experienced 150G - 130G with balloons only would, for most people, still be survivable IMO. Survivable doesn't mean no injuries - or even pleasant. 100G is a very rough estimate for fatality. There is certainly a difference between a 90-year old grandma and a fit 25-year old man.

[@DispleasedSwede]

Also, most car accidents aren't going to be a complete stop into a solid wall, going from driving speed to 0 in an instant. Cars often "bounce" to the side. Side impact airbags are mostly designed to prevent you from cutting you from sharp edges. Part of the airbags job is to prevent you from cuts and sharp edges, in addition to cushion the g-force. There was a reduction in g-forces from the balloons. In some car accidents, it could definitely have been enough. The fact that they showed a large reduction from no balloons is proof that it is plausible.

[@Ellerion2]

Ok, just one crucial observation - the clowns were not crashing by a free fall, they had horizontal vector of travel ( where the mass of the car DOES NOT influence the speed of the crash as much as if the car fell vertically). The speed of 35Mph is roughly about 50 Km/h, so that in itself should not be quite as lethal even if the passenger clown was not strapped in but was alert enough to brace himself before the crash.

[@asdads3948]

Mass has influence on the gravitational acceleration? It doesn't matter if you go 50 on a road and crash into a wall or if you fall with 50 and crash into the ground. But i agree that they tested with a pretty high speed, which might not be entirely fair.

[@notfeedynotlazy]

@@asdads3948 50 Km/h is NOT a pretty high speed for a car to actually be travelling at, even at an urban road.

[@d4slaimless]

It doesn't matter if the car accelerated by gravity or by ICE as long as they made it crash at required speed.

[@kikixchannel]

@@d4slaimless When a car falls, the passengers also 'fall'. There is a difference. If you drive horizontally, there is gravity pulling you downwards, so at a 90 degree angle relative to the direction of the movement. Thus, gravity does NOT magnify the crash rate. In a freefall crash, you are actually adding the force of gravity to what you accumulated thanks to the speed. Result is, there's more G's affecting you. If you don't believe there's a difference between moving horizontal and vertical, then just think about it. What direction takes more energy to roll a wheel. When you roll it forward or when you roll it down? Yeah. Those are two completely different situations because the forces are interfering in one while they are working together in the other. There's also another part to it, too. If you crash horizontally, all the energy that pushes you forward is dissipated and there's only gravity pulling you downward that remains. But in a freefall, you and the car are still pulled by the gravity 'forward' even after the crash. That adds extra energy throuought the entire event, and that's also extra mass behind you that keeps on pushing you (instead of slowing/stopping as the momentum was absorbed by the destruction of the cars frame).

2:15 The Germans also had a purely defensive mindset. While they were initially on the attack once trench warfare set in they switched to pure defense as they were on French soil and so they could just wait for the allies to attack them which they did many times. The Germans were fighting a 2 front war and so they minimized troops on the western front as much as possible to sent as many to the east as possible to beat Russia and then launch a massive counterattack on the west once Russia was defeated. This meant that the German Trenches were permanent while those of the allies were temporary.

I think that the main reason why trenches zigzag is to not expose every single soldier to the enemy when and if the enemy enters said trench. A couple of enemy soldiers with a light machine-gun in a straight trench could finish or wound every single soldier in it. Trenches had been used in the past where artillery did not exist. Another thing to remember is that airburst shells reduced the advantages of zigzagging trenches to a significant extent, as the shockwave starts higher up, thus reaching more of the trench system. With that said, against impact and delayed fuzes, zigzag trenches do offer a lot more protection, as the fuzes will initiate upon hitting the trench or shortly after.

[@FluffyBlueCow]

There's a serious flaw in dropping the car as a test... In a normal car, your body shares the acceleration of the car, which at cruising speed is zero. Then when you hit something that's the starting point of the sudden deceleration. In the clown test, the 'people' are now rapidly accelerating as the car falls, then thrown into sudden deceleration, greatly affecting any possible results.

48:16 everything is not in the last number. if the first measurement is at the same distance and before the first curve in all cases the dampening effect should also be about the same in all cases, but was significantly stronger (76 vs 60 vs just 39) in the rounded trench so the end result of rounded trench is dampened more (from 76 to 8 is by 68) than at square (from 60 to 7 is by 53). it's as if different amounts of explosives were used.

They would call this tv show racist nowadays. Sad to see how everything has turned into unison and all kind of dissidents are immediately cracked down.

Sad to see the 2 helium balloons that didnt fit in the car float away... and to see them straight up spray paint directly into the ground... not the most nature friendly show

All of humanity is polluting our every medium, land, sea and air for years and years, exponentially as technology progresses( as does the population overall). But... I think the disclaimer would be something like : No sand grains were seriously harmed during these takes compared to e.g. the Sedan Nuke or the creation of the Soviet Nuclear Lake. (the latter even still contains radioactivity in the "water")
