What is it about?
Vapour bubbles form in water when it is suddenly exposed to strong tensile stress. Small gaseous nuclei on the surface of particles present in the water are the origin of the bubbles, and the initial bubble growth makes the particle move away from the bubble at high speed. This is shown experimentally, and it is explained theoretically, hereby revealing a source of cavitation bubbles in water.

Why is it important?
Often cavitation is a serious problem in hydrodynamic flows, but it also has valuable applications. Therefore it is important to know why and how it arises.
