: : Any spin induced on a paintball must spin not only the shell of the paint, but the liquid paint itself. : : Take a glass of ice water. Rotate the glass (shell) around in your hand. You'll see as the glass makes on revolution the ice water (paint) stays relatively put. Keep twisting the glass fast enough and the ice water will start spinning faster than you're spinning the glass. You can't get a decent accuracy with the shell spinning at a differenct rate than the paint. Just my .02 : Point taken. A few things to consider though... Paint is much more viscous than water. The volume we are dealing with is also much less than the volume in a glass of water, thus it is easier to get the fluid moving as there is less of it. Paint is also composed of several components which are all different in density. If a paintball starts to spin on one axis, I would imagine that the denser components would be separated and be pulled towards the shell, whereas the rest would stay closer to the axis of rotation. Of course, that's only a theory. It assumes that one can separate the components by centrifugal forces. : Spitzer Just to add another variable - paint thickness varies a lot. I've seen RP Marbs that had a bubble in each ball - looked kinda like an eye. When the ball was turned upside down, it would take a minute for the bubble to move to the top of the ball. I've also seen cheap paint that the bubble would only take a couple of seconds to rise to the top. Tom :)
