None of the answers for the question "why clouds are white" got to the
core of the matter.  Obviously they scatter light better than their 
surroundings -- why (Rayleigh scattering is only part of it)?

Hint: estimate an upper limit on the size of a water drop in a cloud. What
would you see as you looked at a cloud whose water drops were increasing in
size through this limit?
