I've got one of these specially made actually.  It's a specially blown glass
"bubble" in a shape similar to a light bulb... (bulb at the top, a pin goes
up through the middle point upwards and the mill sits down on top of it on
the point) it is pressure sealed and thus there is not very much resistance
inside against the "mills".

If I leave it in the sun it gets up to about 120 RPM.  I find it quite
interesting to observe :)

My opinion, light creates pressure, therefore photons have mass (which makes
sense when you think about how light reacts with things like liquids, or
gravitational lens etc).  But I'm not well enough advanced to be able to
prove any of that yet.

BTW, this should be moved to p.o-t
