Studying cavitation in space |
Bubbles collapse without weight (Sep 13)
http://physicsweb.org/article/news/10/9/6
Cavitation is an unusual process whereby tiny air bubbles grow and
collapse inside water droplets. It can be a big problem in industry,
where it can erode everything from ship propellors to pipelines. Now,
however, researchers in Europe have obtained new insights into this
process -- by studying cavitation in space. The work let them create
isolated, spherical droplets of water that would be impossible to make
on Earth (Phys. Rev. Lett. 97 094502)

Actually, those are bubbles of *water vapor* formed when the dynamic
pressure of the water drops below the vapor pressure - the water
evaporates.
