Collapse of a spark-generated bubble near rigid or deformable surfaces is studied experimentally with a high speed cammera. The formation of a bubble wall jet has been observed and discussed. Results from experimental studies on the effect of liquid viscosity on bubble collapse near the rigid wall are also presented.
