This movie shows numerical simulation of the dynamics of bubble shape for the initially excited shape modes n = 3, 4. It is seen that the bubble translates along the x direction. Such motion can be explained by the energy transfer from the excited couple of shape modes to the mode n = 1, which corresponds to the bubble translation.
