Abstract The soap bubble, as a nonlinear fluid, has a very complex non-linear response to external actions. This paper attempts to give a theoretical explanation to this process by a small and light sphere which has similar size of soap bubble and travels in suds, from the view point of statistics. The experiments show that the original description thought is reasonable.
