The video shows a fluidized bed of sand. Using air compressors and plastic tubing buried under the sand. The sand is seen to behave as a fluid.

Very cool, I like how you are only showing us what’s happening at a small part in the setup and how the air and sand are acting.
The slow motion here seems to work well to highlight the details that you wanted to be highlighted.
I like the experiment, the focus of the camera is going in and out and makes it kind of distracting from the fluid flow.
I like the focus on one large build up and “explosion” for the air bubbles
I like the clear instabilities in the sand, what is the playback rate of the video?
I like the use of slow motion here. Really highlights the motion of the sand!
I like the focus on the section view and the slow motion.
Nice editing and it’s good that you slowed it down. Cool choice of music!
This video shows very neat flow physics of compressed air. The slow speed of the video is a nice touch.
