This is the precursor of all the other candle holders and river rock products that you see here on this website. Its original name was “self-balancing candle holder”, aka earthquake proof candle holder (see history). A smooth river rock lends weight and stability to the base consisting of an ascending movement of steel. The piece supporting the candle pivots from the top of the base like a pendulum whose counterweight is a smaller river rock. The cup is a by-product of car muffler manufacturing.
