How do those Harmony balls, or Baoding balls, actually work? Answered

The most I've gotten is it's a "sphere within a sphere and there's a bell", but I don't want to cut one of mine open. Is it an ancient chinese secret.? I thought it might be like a rain stick with thin metal soldered to the inside surface with a loose ball to strike them.

I cut one open, inside are a number of metal rods and a ball bearing that hits them as it rolls around. I may still have some pictures somewhere.

Thanks! That's what I thought was in there, but all the chinese websites made it seem way more mysterious. One said it was a "sphere within a sphere", which can be interpreted as a ball bearing in a sphere. Thanks for sacrificing a ball for curiosities sake.
