Did you know that the smaller it is a drop the higher the pressure in it due to surfece tension, this is why the drops in the 3rd picture are so spheric, they must be very small. ParkerMB i like that the drops on the caterpillar magnify the tiny spots. treehugger- interesting fact, i did not know that. but yeah, it makes now sense that a perfect sphere would be the most efficient and only natural shape for them.
