a:  hydrophillic surface of a lipid bilayer ~
b:  the surface of a pond
What:  
The commonalities are the fluidity of the watery surfaces. If you put a small boat on the surface of pond, it will float and slowly move around. The media in which it is sitting is fluid. The frozen surface of a pond is solid. If a small boat were place on top it would just sit there, motionless.
