Catching an Explosion in Water at 5 Million FPS - The Slow Mo Guys

5 million frames per second played back at 25fps is the equivalent of slowing down 1 second of real time to over 2 days of playback.
Big thanks to the Colorado School of Mines for letting us back and for the use of their explosives and Shimadzu camera.

That 5M frames shot was absolutely incredible. This is really something where you need exactly these kinds of cameras to see all the detail.
-
Did we mention already how glad we are that Dan is back at it with his cool weapons and explosives expertise? We love you Dan..
-
I love that Dan just knows all these things. It's refreshing to hear someone lay down so much knowledge I don't know about
-
The inversion of the 5 million fps shot is absolutely insane. That’s actually one of the coolest things i’ve seen on youtube
-
That 5M FPS shot was phenomenal…wow, this may be footage never seen before. What a sick video
-
That 100k water shot was actually incredible. The cavitation wave behind the shockwave, the black tendril climbing down the core, and the thick cracks chasing behind
-
17:45 look at the corkscrew of shrapnel shredding through the water right next to the “smoke monster”… that’s so cool!
-
I’d argue that the 5M shot is one of their best shots of all time. Even the fastest shots they’ve had didn’t show much. This shows everything, including exactly how the explosive worked. Fantastic
-
That cone inversion is one of the coolest things I've ever seen, no joke. I've known about how the physics of shaped charges worked in detail for many years but there is no substitute for really seeing it happen!
-
The prediction of 15:14 is really showing that Dan is experienced. He's enough of an expert to admit what he doesn't know.
-
Always love videos with explosives as Dan gets to flex the knowledge he learned in the army. Really cool episode.
-
Hey, it's insane to realize that the speed of light is 3×10^8 m/s, or 30 cm/ns, meaning that with the 5 million FPS footing you could start to see the effects of the speed of light limit. You could actually build something to observe this effect. For example an array of mirrors at different positions, all reflecting the image of a unique explosive charge toward the camera. The image of the explosion would then appear at different times in the different mirrors due to the limit of the speed of light.
-
Glad they let you boys back! More mental slow-mo for us! Not to mention what a pleasure it is to watch Dan show his expertise
-
SlowMoGuys still nailing it every video ! These guys have been consistently on point for so many years now !
-
I love how you guys know exactly what we want. Never had to rewind cuz u guys did it for us like 10 times that was perfect.
-
Sometimes we forget Dan was literally a military munitions expert... I'm so glad he was!
-
Interesting note: The SPACE between impact layers has been proven to be extremely effective in stopping stupidly fast impacts, as the space allows the shrapnel and debris to spread, effectively absorbing the kinetic energy of the projectile with each additional layer. This is, in fact, so effective in impact protection that a variant of this idea is used to stop micrometeorites from penetrating spaceships, something known as a Whipple Shield.

This channel has to be the #1 for satisfaction and the desire to want more in one sitting. Love it.
-
I cannot get enough of this shimadzu camera footage. I'm blown away. This is a whole new level for you guys.
-
You know... YouTube has it's faults and flaws, but I'm really glad that they provide a platform for people like you guys to shine. You guys rock! 💙
