Two types of experiment were studied: experiments on oscillations of bubbles attached to a tip of capillary, and experiments on a bubble rebound from a horizontal solid surface. The bubble deformation is similar during the rebound and during oscillations. In case of rebound, the bubble impacts on the glass wall. In oscillation experiment, bubble is deformed by a movement of capillary on which the bubble grew. The bubble size in both experiments is 1 mm and experiments are repeated in aqueous solution of several surfactants (α-terpineol, SDS, Triton X- 100, Triton X-45 and CTAB) at various concentrations.
