You know what a Radiometer is, I have two of them.If I set them in the
Sunlight or near an Incandescent light bulb, the little black and white
vanes spin around fast.If I set them near a flourescent light, the vanes
do not spin around at all.Light, real Light has mass and pressure.


That isn't what makes the vanes go around. If it were light pressure,
both sides of the vanes could be the same.
