This is a ball crashing into a wall of cubes, which magically reveals the name of a program which I used to make this simulation! I am trying out a new feature for my simulations, the ability to change the speed! Just click one of the buttons, and the video will slow down to be viewed better! Unfortunately, the frame rate slows down then the video slows down. There is no way to fix this.
I used Blender 3D 4.1: https://blender.org/download/releases/4-1/ All of my Blender 3D simulations are on my studio: https://scratch.mit.edu/studios/34787653
