The bubble life times of various water samples were measured in the laboratory. The statistical features of bubble life time on water surfaces are discussed. The measurement results showed that the distribution of bubble life times of various water samples follow a Rayleigh distribution and that the mean life times are a function of the bubble sizes. The total of life times of various sizes for tap water is 2.24 s, it is 2.98 s for Delaware Bay water, and 3.89 s for Atlantic Ocean water, respectively. Comparing the statistical features of the bubble life time generated under different conditions, we found that the bubble life times are independent of the methods used to generate them.
