A movie of an explosion penetrating an object in super slow motion at a maximum of 5 million fps
Catching an Explosion in Water at 5 Million FPS --The Slow Mo Guys --YouTube
Gavin (left) and Daniel (right) from The Slow Mo Guys are here.
This video was created with the support of Amazon's original work '
The high-speed camera ' Phantom T3610 ' that was used for shooting at 1280 x 720 pixels (720p: HD image quality) and capable of high-speed shooting at 120,000 frames per second (120,000 fps) ...

In addition, we also use the high-speed camera '
Navy SEALs use shaped charges to destroy the locks on closed doors. This time, we used multiple high-speed cameras to capture the moment of the explosion using the molded bomb that can crush the target at a speed of 10 km / s. First, place three copper plates and take a picture of how the molded bomb penetrates the plates.
With a normal camera, the moment the explosion occurs, the copper plate tilts and only raises smoke, making it impossible to recognize what happened.
If you check it nearby, there is a big hole in the part where the molded bomb was installed ...
Although the second piece also penetrated, the hole was small, and the third piece could not penetrate.
Checking this with a 1000fps slow motion movie is as follows. Even in slow motion at 1000fps, you can only see the light spreading at the moment of the explosion, and you cannot see how the blast penetrates the copper plate.
However, if it is a slow motion video shot at 63,000 fps ...
The appearance of the blast penetrating the copper plate is firmly contained.
However, the light generated at the moment of the explosion was too intense to confirm the details.
In the case of slow motion video shot at 1 million fps, a blast hits the copper plate ...
Penetrates the copper plate.
Furthermore, the explosion touched the second copper plate ...
The appearance of the blast spreading on the surface of the copper plate is also firmly contained.
Next, I decided to line up 10 plates and burst the molded bomb.
Click the button.
With a normal camera, it looks like all the dishes have blown off in an instant.
Fragments of the molded bomb sank into the base where the plate was fixed, and even with a screwdriver, the debris could not be removed. It tells the tremendous power of the molded bomb.
So, from here, let's check the slow motion video taken with the high-speed camera. First of all, from the video of 1000fps.
You can see that it is bursting from the plate in the back, but it is not enough to shoot the plate bursting one by one ...
The plate will burst almost instantly. You can see the pieces of the plate scattered toward the camera.
Then a slow motion video shot at 94,000 fps.
At the moment of the explosion, intense light spreads, and about 3 plates in the foreground (left) are swallowed by the light ...
The explosive light spreads further.
From the 5th and 6th plates, an explosion penetrates the plates.
The visual beauty is like a scene from an action movie.
The detonation has reached the 8th plate, and the 9th and 10th plates seem to have been broken by the shock wave caused by the explosion.
Furthermore, the moment of the explosion in the slow motion video of 1 million fps is as follows. First of all, the explosion penetrates the first plate.
When you penetrate the second plate, it looks like this. The blast spreads on the side of the plate on the molded bomb side (left side), and the blast is kept to a minimum on the side through which the blast penetrates (right side).
If you check the slow motion video of 1 million fps in the up, it looks like this.
It is difficult to understand because it is monochrome, but you can clearly see how the blast spreads from the hole in the plate, makes a hole in the next plate, and the explosion that does not enter the hole hits the plate and diffuses.
In addition, with a slow motion video of 5 million fps, you can see the moment when the explosion occurred more clearly. A circular shock wave is created at the moment of the explosion ...
A blast pops out from this back ...
It penetrates the shock wave and extends forward.
Finally, the molded bomb is detonated into the water.
With a normal camera ...
Water spatters with the case in an instant.
I don't know anything other than the tremendous power to blow off the entire case.
However, when I shoot with a high-speed camera, the case cracks and cracks ...
It is possible to capture clearly until the moment when the water splashes.
Furthermore, in slow motion video at 94,000 fps, black smoke and explosion light generated at the moment of explosion hardly occur in water ...
You can see how the explosion grows toward the back of the case.
The case cracked when the explosion went through the water to some extent ...
Along with this, black smoke and bubbles spread, and finally the case burst.
When you rotate a 94,000fps slow motion video sideways, it looks like this. First of all, the central part of the explosion goes into the water ...
The impact spreads into the water, and the air bubbles make the explosive core that travels underwater invisible.
The explosive center part glances from the back of the bubble
And the case is cracked and finished.
The following is a side-by-side video of a slow-motion video of breaking a plate with a molded bomb.
The last one was shot with a slow motion video of 1 million fps. The explosion touches the water ...
A blast spreads on the surface of the water. However, it was not possible to confirm the state of the explosion traveling underwater in the monochrome slow motion video.
