A Drop in a Vacuum

A Drop in a Vacuum


Some curious individual wondered if the effect of a drop of liquid landing on a surface is different in a vacuum than it is at one atmosphere.


This is the effect I'm familiar with.




Here is a video of  a drop in a vacuum.



 I'm unclear on the physics, but it seems that when the friction between the liquid and air is eliminated, all the energy is efficiently and uniformly dispersed into the receiving body...or something.

I lost the contents of the article, but I remember that what was learned in the experiment had a practical application, which, unfortunately, I can't remember.  Doh!
