Bouncing bubbles
We discuss here soap bubbles hitting a bath of water and bouncing off the surface. We first describe the characteristics of this event, that is, the bubble deformation during impact and the contact time associated with the rebound. Then we propose a tentative scenario for understanding this behavior, which stresses the importance of the transient film of air between the bubble and the bath, preventing the coalescence from taking place.
