Underwater Explosions at 120,000fps - The Slow Mo Guys

[@jackielinde7568]

Too bad they didn't tape up three or four together and light them for a final sequence. That would be interesting to see the different cavitation balls interacting with each other.

[@theslowmoguys]

Jack Linde we actually did but the gaps between the explosions was the equivalent of minutes of slow motion. Not ever did two explosion balls happen at the same time. Too much variation in the bangers at that speed.

[@SnowIsMyTerrain]

Depending on where you guys are, trying something that could be electrically initiated could be super cool (Oxy/Acetylene pops to mind, but not ideal. It's probably too fast if it actually detonates).

Gav: "Do it at the normal frame rate" Dan: TRIGGERED 4:29

[@TheEvertw]

About your question at 5:35: 'whatever is inside it'. The banger produces a certain amount of hot gas, which is what causes the light. That is generated suddenly, at high pressure. That high pressure spike pushes the water away in a spherical bubble. So initially, the bubble is filled with gas. The water around the bubble is accelerated by the gas pressure. As the bubble expands, the pressure in the bubble decreases, causing its temperature to drop. Thus it stops emitting light. At some point, the pressure in the bubble drops below the ambient pressure, and will start to decelerate the waterfront around the bubble. But due to the amount of kinetic energy in the water, it can not stop immediately. The bubble will continue to expand even as the pressure in the bubble drops to near vacuum, but the speed of the water is decreasing. At some point, the water comes to a stand still. At that point, the bubble is at its maximum, and inside is a near vacuum. The water will be drawn back in to fill the vacuum. As that happens, the pressure inside the bubble will rise again, heating up the gas inside. At some point it starts to glow again, just before the bubble collapses. During the internal collisions as the bubble collapses, most energy of the blast is dissipated. Thus we do not see a second spherical bubble. What remains is an irregular 'cloud' of combustion gasses, at near-ambient pressure. This cloud is pushed to the surface by the water it displaces. So the short answer is: the bubble is filled with a modest amount of combustion gasses. When the bubble is at its maximum, the pressure inside is near 0 Pa (absolute).

Justo eso pienso que pasa

[@theaceofspades485]

It does all seem very familiar. A single massive gas explosion throwing out millions of tiny energized particles some of which attached to trace amounts of water, vapor,gas and oxygen. You could imagine for a insignifcant small scale amount of time it bacame a galaxy full of hot,cold, dry,and violent enviroments and within this it produced a life form so small it actually thrived on it's own plane of time, space, and exsistence. It could never be recorded or reproduced,saved, or made perfect, but only for it's limited chaotic time it thrived. Unfortunately for them the same force that originally created this massive vaccum of possibilities was in fact their own perfect failure as it all got pulled back in and went dark.

It would be nice to see interaction of 2 or more explosion cavities.

[@antivanti]

It's interesting that the initial bang isn't the one that throws the most water (or creates the most devestating shockwave) it is when the cavitation collapses with all the energy of the explosion hits that incompressible water and bounces back faster than the initial explosion.

[@Kosaro1234]

[@antivanti]

[@DeathBringer769]

Water is slightly compressible. We often treat it as incompressible when doing fluid flow calculations because the pressure changes involved are too small to make an appreciable change to the density. It makes it much simpler that. But that is just an approximation. It’s a very good approximation, but it’s still just an approximation. Under really extreme pressures, water can be compressed into a solid with various lattice structures different than ordinary ice. In fact it's predicted that ice (frozen *water*) under enough pressure will become a metal (this has been variously estimated to occur at 1.55 TPa or 5.62 TPa) You might find these in exoplanets with very deep "oceans", or gas giant planets in which water is the predominant material. en.wikipedia.org/wiki/Ice#Phases

[@jayjayx5x1]

well actually thats a misconception, as the big bang wasn't well a big bang, yeah it was a rapid expansion, but it wasn't a properly explosion (there was more order to it) and it wasn't big, it was everywhere. the whole idea that the big bang had a center point is complete bullshit, one person who keeps using this non scientific explanation of it is richard dawkins, which makes sense since he likes to piss people off and is a bit of an a hole. anyway besides the point, when george (the guy who invented the big bang theory) a catholic priest was examining stars, he noticed they were slowly expanding away from each other, he tried to find a center, but long story short there was none since everything was expanding from each other equally, yes you would be correct that everything in our known universe (the part of the universe to which we have received light aka photons from) was more or less comprossed down to a point, but not a single point as to where ever you go or a point you pick is in its own way the center of an expansion. anyway point is big bang wasn't a centralized explosion it was all over the universe, before the big bang the universe was hot and dense, and still very much so infinite, but with the laws of infinity it has an infinite amount of space to expand into, even if it wasn't 100% infinite once something is big enough the laws of infinity apply to it. the main thing about the big bang was that all current physics, gravity, laws of mass, time etc. didn't exist in this compressed state, and nor did any atoms everything was in its purest forms, hence why subatomic particles have no age as they have no beginning in the construct that is time, maybe they didn't always exist but since the construct of time didn't exist there is no real way to know. but yeah the big bang doesn't actually mark the universe going bang and suddenly existing, it actually just marks the universe beginning aka the beginning of time itself and the space time continuum, and btw the big bang is a horribly inaccurate name, a much better but less catchy name is the everywhere stretch as that is what happened. now time may have existed before the big bang if you subscribe to the possibility that if the universe can expand it can compress meaning that this wasn't the first big bang, and that before there was a big compression, meaning that the universe may very well have its own lifecycle. once could attribute this miraculous event to a higher power, aka God, i myself believe this as i deem it logical but lets not get too theological here. the point of this comment was to just inform really, as a lot of people misunderstand what the big bang really is because of how lies have been spread and the name itself being misleading, multiple sources said the universe has no beginning when the information about subatomic particles having no age was found out, which really shows how little a lot of people understand as the big bang doesn't make the beginning of the universe but instead the beginning of time and physics and most relative science, and the form of matter and atoms, but before there was always some form of particles existing, stuff has always existed before time.

[@elijah111]

I feel like this is simular to the timeline of our universe. A bang, expansion, and then it all collapses back into nothing.

[@myar4931]

I would agree, but studies have shown that the universe's expansion is speeding up, rather than slowing down, so I'm willing to bet that it will only continue to expand. Take that with a grain of salt, though. The universe is full of surprises.

What is depicted here is the physics of the big bang.

It's a combustion reaction, the two main components are CO2 and H2O. The bubble is mostly that and uncombusted fuel. There's a quick expansion, followed by a recompression as the water pressure pushes it back in on itself. As it recompresses, the temperature rises until it gets hot enough to ignite the leftover combustibles.

[@xavierred6936]

That'd be incredible but it is impossible. Given lightning travels at the speed of *light* and strikes at complete random. There are no cameras capable of recording at that speed; even if they could somehow magically get a lightning bolt into center frame.

[@JackToeRip]

even if they could record that fast, which they pretty much cant, atleast not in a really good resolution. They would have to hold a camera outside for a long period of time to get a single strike in frame, recording a couple seconds at insanely high capture rates can become 9 hours of a single second.

Gavin works with AH and Dan's in the military , so they record a lot of episodes when they meet and release it periodically

[@BarrasGarage]

jake newport true i never knew that to be honest

[@BarrasGarage]

Ameya Kashid i also didnt know one of them were military

[@Nipponing]

WTF is this language?

[@L4veyan]

3:50 the left one looks like a star collapsing in it's own gravity.

[@guillaumedruon9369]

Merci pour le sous titrage, je suis toujours aussi fan de votre travail, continuez comme ça. 😁

[@davidheinrich174]

Anything you guys do with explosions is a thumbs up for me :-)

[@TheRainydayvideo]

It looks like some sort of planetary explosion. Amazing!

[@DizzyMoonTV]

FLINT LOCKWOOOOOOOODDDDD!!!!!

[@NS-xo6qe]

This was the inspiration for the mountain fuel explosion in Solo.

[@DANGJOS]

That was soooo beautiful!!!

[@TheTechnoHash]

How 120,000fps in 4K would look like?

[@Cameron-rc5ef]

ArroGant that is impossible at the moment

[@JackBahh]

It would look like 4k...

[@szszsz927]

ArroGant the file size would be like 25 TBs at 4K and 120,000fps

OG my phone has that...

[@codymccormick2613]

I dunno if anyone’s already answered this but in regards to the cavitation bubble, it’s a completely separate reaction! I don’t know exactly how they work, something like the pressure rapidly compressing the air inside the bubble causing it to release heat and light. Mantis shrimp cause them when they fire their hammers!

[@MrCubFan415]

Cody Mccormick The cavitation bubble, when it collapses, is hotter than the sun for a tiny fraction of a second!

[@EmeraldCrocodil]

Mr. Cub Fan 415 3:56 proves it, at least to me

[@lioneleminence3401]

You mean Pistol Shrimp

[@jaybruhill533]

@Cody. I don;t think a compressing vacuum is the same as the magnetic compression you are thinking of. You can't compress a vacuum, right? Doing so means you have the STP of water.

[@geraldmiller1257]

Could be a Super Nova simulation. The expansion and how it collapsed in on its self. Very cool stuff.

[@goldenkillzz7425]

That perfectly resembles a super nova explosion

[@goldenkillzz7425]

It perfectly resembles a super nova explosion

[@NipItInTheBud100]

The coolest shot was watching what the surface water did at the time of explosion! Really cool shot!

[@garyshaw8449]

show a bullet hitting a persons bare chest in slow mo

gary just got burned bro

[@looseyfur3773]

Show a man blowing his load in slo mo 😀

[@MichaelSodapop]

4:55 looks like one of those underwater nuke tests on KZbin.

[@mikeb.1487]

Keep it up, lots of satisfying slow motion.

[@charlesfuentes6809]

The next "Star Implosion" for an upcoming Birth of a Black Hole motion picture...or Documentary. Good Job, fellas.

[@AaronHamm]

Re: your question at the end... It's certainly a vacuum. You can test it for yourself to confirm by doing the explosion in deeper water so that the oscillations have a chance to stop and you can actually see the size of the bubbles that rise to the surface.

[@cortster12]

Not a perfect vacuum, given the slight emissions from the explosion, but it is still pretty void.

[@Arikayx13]

The explosion only explodes because solid chemicals are being turned into gaseous ones and then heated. Inside the bubble may be lower than atmospheric pressure but it's certainly not a vacuum.

[@AaronHamm]

Did you read past the first sentence? It's obviously not a perfect vacuum, as was implied by the fact that I note that bubbles will still rise after everything is done oscillating. Free space isn't even a perfect vacuum, so by your implied definition, pretty much nothing is a vacuum. At the explosion's greatest extent, it wouldn't surprise me if the pressure was order of magnitude lower than atmospheric pressure though, so for a rough approximation calling it a vacuum is good enough.

[@cortster12]

Aaron Hamm Technically, an explosion is an expansion of gas in general, so it's just a high-pressure heated gas until the gas cools and then the vacuum forms. So it isn't a vacuum until it becomes a vacuum by the expansion.

Best way to get replies on a post? Be casually correct with opportunities for people to make pedantic points...

[@jacknoymer5093]

Dan: sneezes Dan: get that in slo-mo Video idea? 😂
