k, problem with the video is the boy is dragging the bottom of the loader across that mat as he does the drop. i belive those mats are rubber backed and furry on top as you can see. now, if we go back to secondry school physics, what happens when we rub furryness against polycarbonate?? yes thats right, static electricity. WHEEEE.
so, the same thing could possibly happen with dirty reballs that are slightly furry, but they would have to be actual hairballs for that to happen. My two pence...shenanegans!!!!
