I'm just thinking about those toys...that you push around. It has a clear dome, and when you push it around, some kind of mechanism tosses all the coloured balls around. I never owned one myself, so I don't know how it works. That might help stop the jamming. A stir stick is a really funny idea though. I'm just picturing a big wooden stick rotoating around, moving the balls around.
