Lathe turns a smokey piece of acrylic into a reflective ball!
Diamond cutting tool turns a piece of smokey acrylic into a smooth reflective dome. They use a diamond lathe, and it is one of the most satisfying things to watch, it becomes so clear it looks like a mirror. It’s hard to tell just what they were doing so we did some searching in the comments. We don’t know what the end plan for this is maybe it’s a glass eye or a lens for a drone,
