Floating a bed of air

I remember a while back now that I saw a video demonstration (by NASA I think) of a large heavy metal cylinder container (around one metre in height) which floated on a bed of air from the nozzles on it's base, easy enough to push around with a single finger, until the air was turned off.

This on a metal table in a controlled laboratory environment.


Does anybody else remember this?

Not that specifically, no. But have you ever played air hockey? Or seen an air track? The principle is the same.

I know, but I need a direct reference, and to video if possible.

I found it, the technique is known as "Air Bearings" !

h/t:

I didn't find the clip however, it could have been the BBC/Tomorrow's World, and it may well have been NASA. However, that was what I was looking for.
