摘要：

The results of experiments on the study of stability of the dome of a water bubble rising through a salt solution are presented. The experimental results are obtained using the PLIF method by recording the flow in the plane that coincides with the axis of symmetry of the bubble, The experiments demonstrate the possibility of the development of instability in the vicinity of the pole of the dome of such a bubble in accordance with the previously published results of computational simulation.
