Cavitation in slow motion (37,500 fps)

Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid’s vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called “bubbles“ or “voids“, collapse and can generate shock waves. These shock waves are strong when they are very close to the imploded bubble, but rapidly weaken as they propagate away from the implosion.
