The oft-quoted 1-to-10 rule, that the diameter of the top jet drops is about one-tenth that of a bubble bursting in seawater, holds for bubbles of <500 μm diameter at about room temperature. The diameter of the second jet drops is about 8% larger than that of the top drop. Some of the lower drops are larger and some are smaller than the drop. Both drop size and ejection height decrease with decreasing water temperature. Jet drops are produced from bubbles estimated to be as small as 10 μm in diameter. ¿ American Geophysical Union 1989
