I wanted to make some special "underwater juggling balls". They'd be the "normal" size, but I'd assemble them so they're effectively neutral.aquaticmatt:I like to juggle seashells underwater. It' amazing how easy it is if they're not too small.
Imagine "juggling" where you merely take a ball, set it in the air, grab the next one out of the air, and so on.
(I usually settle for hanging on the deco bar behind the boat and blowing bubble rings for the new students.)
