    Ring is cut from a white plastic bottle from pool chemicals.
    Paint job on the coke bottle was fun. Sprayed some black paint into the bottle, put cap on, shook it up. Took cap off and let it dry. Repeated twice. Thus all the paint is on the inside. The fins and the inside of the ring were blackened with a marker. The red oN the outside of the ring is Mylar tape.
