Dear list members:
  For those that are interested in some interesting sites take a look.
For those that are not interested...delete. Thank you. Dirk

The Rayleigh-Taylor (RT) instability occurs any time a dense, heavy
fluid is being accelerated by light fluid such as is the case with a
cloud and shock system. Two completely plane-parallel layers of fluid
are stable, butthe slightest perturbation leads to tangential
``gravity''. Any small local minimum will quickly be amplified by
material flowing down under the influence of this force. Dimples are
quickly magnified into sets of inter-penetrating ``RT fingers'' as the
heavy material moves down and the light material flows up. This process
is evident in many terrestrial examples from boiling water to weather
inversions.

This was a java simulation of an asteroid striking Jupiter as an example
of Rayleight-Taylor instability....but the link seems to be broken.

Working simulation of comet striking Jupiter (not quite as nice) but at
least it comes up.
