A little bit of air flowing out from under this billiard ball keeps it "floating" in place. The ball is free to spin with little friction and will keep spinning for a very long time.

I like the demo Mr. Nord, watching it before colloquium as usual

Cool video.Did you have to do any sanding or was 3D printing alone good enough for the tolerances?

Printing was not smooth enough. I heated the surface and then jammed a ball onto the surface.

This is really cool! Can I contact you somehow? I've got a physics project and for that I must make air bearing device. I just have some questions and I need answers :)
