Seeing the slow development of the flow here was really interesting as you can see the cavities forming within the sane before the air can fully escape.
I think not including music gives more focus on the phenomenon
I like your experiment and capture of it. The fluid motion is nice, but the frame is moving around (I am assuming you hand held the camera). To help compliment the fluid motion having the frame stable I believe would enhance your intent.
Really highlights the liquid nature of the sand! Nice work!
Nice description and visualization of the physics, did you slow the play rate of the video down?
Great idea to start off the video with no air and show the threshold of the compressed air flowing through the sand.
I like how you could see the top of the surface where the compressed air is leaving.
