Hi folks, I agree that the eroding copper and polish residue creates some of the foam, but I believe the majority of it is the result of the sickness coming off the bottle, the small amounts of PVC coming off the inside of the tube, and the nylon, plastic, silicone, rubber, etc. coming off your stopples and 3 or 4 prong "fingers". I have noticed considerably higher amounts of foam when tumbling very sick bottles, using new tubes or stopples, or using any cutter which will eat away at the inside of your tubes etc. more than the polish will. Of course if you are using any type of detergent/ SOS pads, etc to clean up and rinse off your bottles before loading them up for a spin, even the small amounts of detergent residue that make it's way into your tumbler, will increase your foaming action. Just my opinion for what it's worth.
