lcoombes: You need to be good at doing 2 ball isolations in both hands to make this trick look decent. It is pretty simple once you can do that, though. Simply do an isolation in each hand with the balls rotating in opposite directions. You can also do this with the balls going in the same direction, but at opposite sides, for a different effect.
