Thanks for the confidence, I was just looking around Amazon for glass jars and found several sizes available, I did run across a spiral SS wire ball that could be dropped inside the jar for an agitating effect , I suppose it would rattle around like a ball in a spray can , I'm curious if it would have a beneficial effect or not. I really like the cradle feature of the glass jar example above.
