This is what happens when you watch a drum shockwave at 10,000 fps using a super slow-motion camera.
Paint Shockwaves on Drum with Robot Camera at 10,000 FPS - The Slow Mo Guys - YouTube

The movie of shooting a bass drum with a slow motion camera was also posted by The Slow Mo Guys in 2016. In the movie below, a slow motion camera is used to film how the shock wave spreads by placing six colors of paint on the bass drum and then hitting it.
Gavin says that because the 2016 movie's goal was to capture beautiful footage in 4K, it could only achieve about 3000 fps, which was not enough to capture the shock waves in detail. Therefore, in the new project, he is using the high-speed camera ' T4040 ,' which can shoot at 9350 fps at full resolution, to capture the bass drum shock waves in more detail.
First, just like in the previous video, we put paint on the bass drum. In the previous video, we used 6 colors, but this time we created an 8-color gradient.
With the paint lined up neatly, the bass drum is struck with a mallet. In the super slow-motion video, you can clearly see the mallet lightly sink into the drumhead.
After that, the paint appears to jump up almost simultaneously.
When photographed from the side, it can be seen that the impact is stronger near the point where the mallet was struck, and weaker further away.
Next, we brought the camera close enough to overlap the bass drum, positioning it so that the shock wave was approaching the camera.
The moment you hit it with a mallet, the entire drumhead ripples.
The paint splashed up first where I hit it.
After that, the impact does not come in waves, from the hit position to the center to the front, but rather appears to occur almost simultaneously in the center and the front.
By using a robotic arm, we can also take photos from directly above.
When photographed from directly above, it was clear that the impact was transmitted in concentric circles.
