I believe that’s one of the reasons they typically use an air burst: the combined effect of the shockwave and the shockwave’s reflection maximizes the overpressure.
The shockwaves turned out really nice, we managed to guess height of the pole pretty well 😄 You should also check out this weeks press video, there is good mystery frame from high speed camera to solve ua-cam.com/video/vaLh78WIH14/v-deo.html
@@scrappydoo7887 But doesn't propagate as far, so unless you have a properly massive explosion, fragmentation effects will be rather more effective at causing damage.
I've been in the blast radius of several IED's. My worst injuries came from a 122mm rocket warhead that was detonated approximately 10 Meters from me. It turned out to be a White Phosphorous shell. The blast hit my left side, and it felt like someone decked me with a roundhouse kick. I remember going gray for a few seconds and coming to with the trees and bushes around me on fire, and acrid smoke making it hard to see. My immediate concern was for follow on fire, which the Insurgents in Iraq had a habit on doing on occasion after a blast. My Squad Leader and I both laid prone, guns out, with one arm patting down my body checking for blood or heaven forbid something missing. I was burned across the left side of my face, and my left forearm where my sleeve was rolled up. After a minute or so, we got back up and with the help of fellow Platoon members got back to our HMMWV. The Medic gave me a quick check and an icepack to help with the burns. One of the Soldiers got hit worse than us, and he went to render aid to him. I lost quite a bit of hearing permanently on my left ear. I consider myself lucky that the shell wasn't an HE (High Explosive) because at that range it would have shredded all 3 of us. So all things considered it was a "Good Day". ___________________ Another blast I remember distinctly was on Route Irish (the main highway between the Baghdad Airport and the Green Zone). I was in the turret position when an VBIED (Car Bomb) went off a couple hundred meters in front of us. The blast force was enough to knock me into the back of the turret. We were the first unit to arrive on scene, really in a matter of seconds. There were a couple armored Mercedes ripped apart that belonged to a British contractor (we learned later on), and several civilian vehicles riddled with shrapnel and burning that were collateral damage. One of the civilian vehicles was a white station wagon. It was torn to hell and burning. The driver was dead still sitting behind the wheel. Off to the side another body was smoldering. As some of our Platoon came up to her, she was able to speak long enough to identify herself as an American. Her name was Marla Ruzicka, an Aid Worker who was in Iraq helping people hurt by the war. She was so badly burned that when they lifted her to the stretcher, much of her blonde hair stayed melted to the asphalt. She was the first to be Medevaced out but died during the short helicopter ride to the hospital. ___________________ Explosives are fun to watch, and if you're careful fun to use.

@Ms Moon Boo why's everyone gotta assume that every story is a troll, things actually happen to people sometimes, not everyone sits on discord all day in their moms basement
@Ms Moon Boo I was a Sniper attached to the 1/69th Infantry Battalion NY-ARNG, part of the 256th IBCT LA-ARNG during deployment to Taji (Camp Cooke) Iraq, and later on Baghdad (Camp Liberty/Victory) in 2004 -2005. You're more than welcome to verify that. You can also verify who Marla Ruzicka is. Beyond that, I really don't care what you think.

What is cool is that at 4:55, you can see not only the blast wave being reflected by the ground, but even combining with the direct wave to form a Mach stem!
@@sperzieb00n Nuclear weapons generally try to release as little short-wavelength radiation as possible in the initial blast because it is a waste of energy that could have gone into a bigger blast radius. They do however produce a lot of heat, which does instantly incinerate everything.
These guys host the best parties and even throw in a couch and some balloons for 20EUR. Catering was ok but the 25kg sausages on a stick were a bit spicy. Overall the kids had a blast. Would definitely recommend them again.
awesome! at 4:57 you can even see the formation of Raleigh’s wave (when the original and the bounced shockwave make positive interference). Same way it works for A and H bombs (that’s why they were detonated above the ground- maximize overpressure minimize radioactive fallout). With nuclear devices the pressure impulse is bigger than regular HE)
@@ddrr5988 I believe the heat vs pressure scale differently. So while this is an accurately scaled simulation for the pressure of a nuclear weapon, the heat emitted is proportionally much less. I.e. at 4km from a 300kt nuke you will get your skin melted off, and clearly that kind of heat isn't generated in this simulation. So I don't think a thermal camera will show a lot. EDIT: see e.g. ua-cam.com/video/2BsOm4xoQs8/v-deo.html for heat effects. Things get torched instantly by the thermal radiation travelling at the speed of light, then the blast wave comes through later.
The blast waves in those videos were just amazing! And with the ashes added in the second video, it looks like the entire tree moves in ashes before hitting the car. Amazing work!
WOW this deserves 1000x more views. Honestly one of the best videos I've ever seen on youtube. The party setup shots were amazing and beautyfull, and the shockwave was captured perfectly.
4:56 You guys even almost were able to recreate so called "V-typej shock wave" which forms out of initial shock wave and one that reflected from the ground and actually uses in real deal nukes to increase their demolishing capabilities! Excellent job, gentlemen!👍🏻👍🏻👍🏻
That Mach Y Stem effect was fascinating to see on a TNT test! One of the reasons airbust is used, the reflected shockwave off the ground meets with the main unobstructed shockwave and they reinforce each other thru constructive interference. Neat stuff.

Always happy to see a new explosion video. A similar test was done in Suffield, Alberta, Canada in 1964. It was done with 500 tons of TNT. That is a lot of TNT.
The ash was a great addition. The slow motion shot of the light flash and the blast hitting the tree and car was great! Don’t forget a real nuke would add the heat and set fire to everything. Great stuff!!!
Kinda ironic that this video was produced seeing how Europe is on Defcon 2 and the United States is at Defcon 3. Other than that freaking AWESOME video guys!
It's cool to see the unintuitive things in the highspeed too, like the Volvo's windows actually blowing TOWARDS the explosion instead of the to same direction as the shockwave is travelling, I don't know anything about anything but I'd say it's because of the exsplosions "sucking" all the air around the area. Also I htought I saw another blast wave but turns out it was the shadow of the only blast wave on the hill behind.
With the second explosion it looked like the most damage occured to the car not so much from the shock wave, but the wave causing a low pressure in the car, then the air rushing in caused the back window to blow out !! Great footage !!
I just came here from the latest Hydraulic Press video and now I have a huge smile on my face. I suppose the fact that's it's a fake nuclear explosion allows me to enjoy it. Yet another epic video. Thanks to all involved. Now on to the Pommijätkät version.
The one thing that is nearly impossible to reproduce is the ball of plasma that a nuke creates within which, and even close to which most things are vaporised, even fairly large amounts of steel are boiled away in an instant (but it is not magic and perhaps more than a lot of people think survives in terms of pure material, (there was a great test with steel spheres spaced from a blast to show this), even being somewhat close to it can be enough to cause 3rd degree burns. So very close to the epicentre you get a totally different blast effect than any other type of weapon which is one of the things that makes them so hard to simulate
"Welcome to the Hydraulic Press Channel! Today we are going to press this sphere of plutonium-239. This is extremely dangerous, so we will use the Blast Shield 9 million..."
Finland boasts a staggering 188,000 lakes. It is also a water-rich country in terms of water per person. Finland has much more available water per capita compared to most countries. Finland also has 98,050 freshwater islands and 80,897 sea islands.
the highspeed of the shockewave is beautiful, a crystal clear well defined lens of compresed air, refracting like a jewel as it slides smoothly over the objects, transforming them.
Sick video dude, the way the ash rips off of the tree then gets sucked back in is amazing... ( Also if you could, what would happen if you put pure sodium in the deep sea chamber?)
You mean, sodium in a glass jar with some air in it, glass jar ruptures at high pressure, water meets sodium? I think that would be either really good or really, REALLY bad. Ever heard of a pipe bomb?
The slow motion footage was excellent. You can see smaller versions of phenomena that occur in full scale nuclear blasts, like the Mach stem in the shots of the blast itself and the short reversal of winds in the slow mo shots of the car.
Look at the leather cushions blowing up from the pressure wave smacking it so hard they rupture from overpressure. Now imagine thats your lungs. Also, the drone shot where you can see the pressure propagate through the forest is super cool.
The part where it blew the couch over and table ring off, was quite amusing. The computer being blown over (display and keyboard annihilated) and the rest flying away, was awesome. Both vehicles got FUBAR and the surprise got a whammo as expected. XD
Large surface area structures are more vulnerable to blast damage due to the increased surface area, so it takes fewer PSI to damage a large (area facing the blast) or tall building. Even low damage can cause fires and overwhelm fire control efforts, leading to greater damage. Large scale damage also affects infrastructure and leads to depopulation, which creates humanitarian crises. The Beruit explosion shows how secondary and tertiary effects are more significant in terms of affecting a country's ability to function and fight than the direct damage of the weapons.
Incredibly cool, thanks the awesome video. A few things- as stated in other comments, there were no objects within the circle and the structures were not modified to account for relative sizes compared to what a "to scale" car would look like. If the objects in this video taking the pressure wave were truly to scale, they would suffer greater damage. This demonstration even with those two above issues demonstrates the incredible mind blowing power of a nuclear blast. A true 300 kT nuclear blast would kill hundreds of thousands of people, and blow any city back several hundred years with regards to it's capabilities and infrastructure if not complete eliminate it. Nuclear war would be more devastating than any one on earth (anyone on earth) can currently accurately predict. And this is only talking about a 300 kT bomb, as there are weapons as large as 50 mT which are over 100 times more powerful than that.
Hell yeah! It's been to long since you last made the explosive vids guys....thanks for posting!💯🍻👍 Edit: that shipping container/ lunch room deserved a Vwhat da fak
10:46 The best part. And i want to tell anyone who doesn't know, that you can control youtube videos frame by frame with , and . . You are welcome. Awesome shockwave!
There are two reasons for elevating the blast. The main thing is that the explosion spreads in all directions; if you are detonating a nuke at the ground level all the energy of the blast that goes up into the sky and down into the ground is just wasted and only a thin, narrow ring around the equator is directed towards targets and each row of houses, hills and obstacles absorbs some of the energy and protects whatever is behind it. The targets nearest the blast get completely obliterated, which is just a huge waste of energy. If you elevate the explosion with an air burst, quite a large area of ground under the explosion has direct view of the fireball and is directly subjected to blast overpressure and radiant heat that is enough to cause widespread damage; much less of the blast energy is going in directions where it is wasted. The other reason is fallout. For air bursts there is very negligible fallout and you don't really have to worry about it. If its an airburst the bomb components turn into very fine dust and spread globally with the winds, and it can take years to come down. For ground level bursts like against missile silos and such the fallout is the main danger. If the fireball touches the ground it will mix with sand and dust and other stuff which then gets sucked up in the rising fireball. This dust is heated and partially melted and mixed with the fission products and comes down quite quickly downwind as fallout. This fallout is not a gas or a goo or something; it is more like various fractions between fine silt and coarse gravel. The main danger is gamma rays from short lived radioactive isotopes; fallout is not a serious inhalation risk, the main risk is that it is just sitting there on your lawn or on your roof and emitting gammas in all directions. In the first few weeks you want as much stuff between you and where the dust has settled; one of the best ways is just to be below ground in a basement as only the fallout on the roof will have a decent direct path to you. In an apartment block without basement you can get pretty good protection somewhere near the center of the building, often a stair well, and not on the top floor. The sides of the buildings don't attract fallout; it is just like sand so it will mostly land on the roof and ground. Fallout only poses an acute hazard for some weeks; after that it poses some small theoretical risk of giving you cancer that isn't really quantifiable. There is a simple rule of thumb; if you know the peak dose rate in an area, e.g. 10 Sv/hr after 1 hr; then it will reduce by a factor 10 for every factor 7 increase in time since blast. It is not exponentially decreasing because there is a mix of isotopes with different half-lives. So after 7 hours it will be 1 Sv/hr, after 2 days it will be 0.1 Sv/hr, after 2 weeks it will be 10 mSv/hr and so on. If you were in a heavily contaminated area and just went down into a basement and sat in the corner that's likely enough to survive acute radiation sickness; if you put a sturdy desk there and stack some shit above and round you (water jugs, potting soil etc) that's enough to survive in very heavily contaminated areas. The residual radiation is not much of a big deal as in games or movies. There will be a bit of strontium-90 or whatever have you leaching from those grains of fallout and it will be measurable in a bone sample but it's not really enough to do anything. The key danger of fallout is the gammas in the first few weeks. We know what happens if you explode hundreds of nuclear weapons in the air, in the sea, on the ground, down a hole; we already tested around a thousand nuclear weapons and a few hundred of those were air bursts or tower shots.

Where the reflection crosses the main pressure wave, that is called the "Mach Stem". Beautiful footage.
And I was just thinking a collaboration with these two channels. You should try it!!!
The slow motion of the pressure wave was amazing
Amazing when you remember this was all just pressure, no shrapnel. And super cool setup, with the rings simulating different distances.
Pressure is far more dangerous in general than frag.
Pressure gets everywhere

It's been a while since you went out and just blew some shit up for science! Really cool video.
Finland is full of bunkers, shockwaves diminish dramatically when they try to penetrate ground
Adding the ash on top of the vehicle was a nice touch! Thinking like a filmmaker now lol
Amazing cross-reference of pressure waves
Man, you look great. Did you lose some weight? Thanks for another great video.
I just came here from the latest Hydraulic Press video and now I have a huge smile on my face. I suppose the fact that's it's a fake nuclear explosion allows me to enjoy it. Yet another epic video. Thanks to all involved. Now on to the Pommijätkät version.
“Party is always nice “
That is shirt material for sure
The one thing that is nearly impossible to reproduce is the ball of plasma that a nuke creates within which, and even close to which most things are vaporised, even fairly large amounts of steel are boiled away in an instant (but it is not magic and perhaps more than a lot of people think survives in terms of pure material, (there was a great test with steel spheres spaced from a blast to show this), even being somewhat close to it can be enough to cause 3rd degree burns. So very close to the epicentre you get a totally different blast effect than any other type of weapon which is one of the things that makes them so hard to simulate
Lauri 3 years from now: "Welcome to Beyond the Press Channel, today we are going to put to the test our first 0.4 kiloton nuclear bomb"
"Welcome to the Hydraulic Press Channel! Today we are going to press this sphere of plutonium-239. This is extremely dangerous, so we will use the Blast Shield 9 million..."
This is probably my favourite video you’ve done
And this is why Anni went back to work at Ikea!
4:40 Party's over.
7:37 !! I have to listen to it many times! And 8:56 LOL! Love this!
You rock man, been watching you for years, I think I remember when the channel arrived.
2:10 "But you could live here" Said by every real estate agent since time immemorial. Location, location, location.
I accept this as my birthday present. Kiitos Lauri!
Did anyone else notice the Girl's hair flick out with the pressure wave behind the wooden screen on the second explosion.?
0:42 - Finland always blows my mind geographically-speaking. The land of a thousand lakes and islands.
Finland boasts a staggering 188,000 lakes. It is also a water-rich country in terms of water per person. Finland has much more available water per capita compared to most countries.
Finland also has 98,050 freshwater islands and 80,897 sea islands.
Finland doesn't exist, it's just a contract between Russia and Sweden, look into it.
"The slow motion of the birthday party going wrong is the best thing."
the highspeed of the shockewave is beautiful, a crystal clear well defined lens of compresed air, refracting like a jewel as it slides smoothly over the objects, transforming them.
Sick video dude, the way the ash rips off of the tree then gets sucked back in is amazing...
( Also if you could, what would happen if you put pure sodium in the deep sea chamber?)
You mean, sodium in a glass jar with some air in it, glass jar ruptures at high pressure, water meets sodium? I think that would be either really good or really, REALLY bad. Ever heard of a pipe bomb?
The slow motion footage was excellent. You can see smaller versions of phenomena that occur in full scale nuclear blasts, like the Mach stem in the shots of the blast itself and the short reversal of winds in the slow mo shots of the car.
Look at the leather cushions blowing up from the pressure wave smacking it so hard they rupture from overpressure. Now imagine thats your lungs. Also, the drone shot where you can see the pressure propagate through the forest is super cool.
Loved the second explosion, looked like the car was getting heat damage from a nuke, a bit like the old video of the house in the early nuke tests.
this is good data. the more frames per second the more science!!!
The double shockwave from ground reflection. 😱
You have a really great sense of humour and an interesting way of presenting things
The part where it blew the couch over and table ring off, was quite amusing. The computer being blown over (display and keyboard annihilated) and the rest flying away, was awesome. Both vehicles got FUBAR and the surprise got a whammo as expected. XD
This is like a miniature Nuke Town test 😂
Also I appreciate that because of the height of the dynamite, the explosion was mushroom shaped 👍
Just described a blastwave like a fine wine. "Strong. But pleasant." 👌🏻
Nice to see more content coming out, but I do miss Anni.
Would the addition of, say, 15 kg magnesium powder packed around the device in a plastic bag simulate the intense light flash even better?
5 micron Aluminium Powder...
Maybe, but it would be hard to video.
Finnish badasses (i.e. all of Finland) during nuclear war: "it was strong, but pleasant."
Large surface area structures are more vulnerable to blast damage due to the increased surface area, so it takes fewer PSI to damage a large (area facing the blast) or tall building. Even low damage can cause fires and overwhelm fire control efforts, leading to greater damage. Large scale damage also affects infrastructure and leads to depopulation, which creates humanitarian crises. The Beruit explosion shows how secondary and tertiary effects are more significant in terms of affecting a country's ability to function and fight than the direct damage of the weapons.
You guys are the best.
" Boiyoiyoiyoiyng " Perfect ACME cartoon sound FX 🤣
Incredibly cool, thanks the awesome video. A few things- as stated in other comments, there were no objects within the circle and the structures were not modified to account for relative sizes compared to what a "to scale" car would look like. If the objects in this video taking the pressure wave were truly to scale, they would suffer greater damage. This demonstration even with those two above issues demonstrates the incredible mind blowing power of a nuclear blast. A true 300 kT nuclear blast would kill hundreds of thousands of people, and blow any city back several hundred years with regards to it's capabilities and infrastructure if not complete eliminate it. Nuclear war would be more devastating than any one on earth (anyone on earth) can currently accurately predict. And this is only talking about a 300 kT bomb, as there are weapons as large as 50 mT which are over 100 times more powerful than that.
Good showing the blast wave, and there will also be thermal and nuclear radiation too.
Hell yeah! It's been to long since you last made the explosive vids guys....thanks for posting!💯🍻👍
Edit: that shipping container/ lunch room deserved a Vwhat da fak
Seemed like it went beyond that and went straight to Finnish cursing ;)
10:46 The best part. And i want to tell anyone who doesn't know, that you can control youtube videos frame by frame with , and . . You are welcome. Awesome shockwave!
I love these explosion vids
To simulate a mushroom cloud, in the Army we used a 50 gallon drum of gasoline with a kilo of C4 on top.
Very very cool experiment/visualization!
you guys actually made a mach stem. crazy
There are two reasons for elevating the blast. The main thing is that the explosion spreads in all directions; if you are detonating a nuke at the ground level all the energy of the blast that goes up into the sky and down into the ground is just wasted and only a thin, narrow ring around the equator is directed towards targets and each row of houses, hills and obstacles absorbs some of the energy and protects whatever is behind it. The targets nearest the blast get completely obliterated, which is just a huge waste of energy. If you elevate the explosion with an air burst, quite a large area of ground under the explosion has direct view of the fireball and is directly subjected to blast overpressure and radiant heat that is enough to cause widespread damage; much less of the blast energy is going in directions where it is wasted.
The other reason is fallout. For air bursts there is very negligible fallout and you don't really have to worry about it. If its an airburst the bomb components turn into very fine dust and spread globally with the winds, and it can take years to come down. For ground level bursts like against missile silos and such the fallout is the main danger. If the fireball touches the ground it will mix with sand and dust and other stuff which then gets sucked up in the rising fireball. This dust is heated and partially melted and mixed with the fission products and comes down quite quickly downwind as fallout. This fallout is not a gas or a goo or something; it is more like various fractions between fine silt and coarse gravel. The main danger is gamma rays from short lived radioactive isotopes; fallout is not a serious inhalation risk, the main risk is that it is just sitting there on your lawn or on your roof and emitting gammas in all directions. In the first few weeks you want as much stuff between you and where the dust has settled; one of the best ways is just to be below ground in a basement as only the fallout on the roof will have a decent direct path to you. In an apartment block without basement you can get pretty good protection somewhere near the center of the building, often a stair well, and not on the top floor. The sides of the buildings don't attract fallout; it is just like sand so it will mostly land on the roof and ground. Fallout only poses an acute hazard for some weeks; after that it poses some small theoretical risk of giving you cancer that isn't really quantifiable.
There is a simple rule of thumb; if you know the peak dose rate in an area, e.g. 10 Sv/hr after 1 hr; then it will reduce by a factor 10 for every factor 7 increase in time since blast. It is not exponentially decreasing because there is a mix of isotopes with different half-lives. So after 7 hours it will be 1 Sv/hr, after 2 days it will be 0.1 Sv/hr, after 2 weeks it will be 10 mSv/hr and so on. If you were in a heavily contaminated area and just went down into a basement and sat in the corner that's likely enough to survive acute radiation sickness; if you put a sturdy desk there and stack some shit above and round you (water jugs, potting soil etc) that's enough to survive in very heavily contaminated areas. The residual radiation is not much of a big deal as in games or movies. There will be a bit of strontium-90 or whatever have you leaching from those grains of fallout and it will be measurable in a bone sample but it's not really enough to do anything. The key danger of fallout is the gammas in the first few weeks. We know what happens if you explode hundreds of nuclear weapons in the air, in the sea, on the ground, down a hole; we already tested around a thousand nuclear weapons and a few hundred of those were air bursts or tower shots.
Great video, love the slow mo, amazing to see metal just crumple and fold under the shock wave.
"Here we have qaar" 🤣🤣
Love u dude ❤️ 🤣
10:28 is so cool, you can see the positive pressure wave then see the smoke get sucked by the negative pressure wave.
