[at-l] Speed of rain drops in a vacuum

[ryan at hack.net (Ryan K. Brooks)]

A neat demonstration for kids (or perhaps adults ;-), is to place a 
beaker of water in a vacuum.  As the pressure drops, the water boils, 
complete with visible vapor, "bubbling" and condensation. 

Then see if you can convince someone to touch the "boiling hot" beaker.

PV=nRT and all that,
