This paper is concerned with the interaction between a weak-plane shock wave and bubbles. The behavior of a liquid microjet produced by the collapse of single and double bubbles was observed using a water shock tube, Ima-Con high speed camera and a PVDF pressure sensor with a high frequency response. The behavior of single collapsing bubble agrees qualitatively with previous experimental results, and it is shown that the present experimental method is effective in investigating the bubble collapse and generation of impulsive pressure. The speed of a microjet within the bubble is estimated to be about 100 m/s, or about ten times as much as that of a microjet penetrating the other side of the bubble surface. In the case of double collapsing bubbles the direction of microjet formation is different from the case of single bubble collapse.
