Re: Purple Side Down
Okay, that's odd. I looked through my photos and almost always the balls with the black or purple halves end up with the purple or black side down (anyone have a ball that is purple on one side and black on the other?) I spotted one or two that did not fit this description (though one may have still been in motion) and several balls that were kind of centered (though half of them were leaning more toward the black/purple side). I've looked at enough photos to think there's something more than an coincidence...
One proposed theory is that the darker sides draw in more heat and are therefore a tad bit softer and the balls then just rest on the softer sides more often.
