I just got my aluball a few days ago, but I've already used it several times. I started really gentle at first because of the warnings of breaking it. I've gotten more vigorous with it, but I still only fill it half full and the ball only impacts the top (very softly) maybe 1 out of every 6 or so shakes. I'm wondering what other people are doing: Super gentle? Just slamming the ball against the top, bottom, and sides, pretty hard? Or what?
