>THE PHYSICS OF COFFEE STAINS.  When a droplet of coffee 
>or ink dries, why is the residue ring shaped rather uniform across 
>the footprint of the original drop?  Scientists at the University of 
>Chicago suggest that as the droplet dries the outer boundary of the 
>droplet remains pinned to the surface and that evaporating liquid at 
>the frontier is replaced by liquid from the interior. Along with this
>flow comes most of the particles (e.g., coffee grounds) suspended 
>in the solution.  This new model may not be of much help in 
>cleaning up after parties, but it might come in handy for various 
>industrial processes.
