This title was chosen only to make you read the abstract. Tiny cloud droplets are actually falling, very slowly. We will talk about how raindrops grow/ shrink as they fall, and about mammatus clouds in this context. We will then talk about "marine snow": biological debris falling through the ocean. This helps reduce atmospheric carbon, so it is important to understand. We know everything about how spheres in Stokes flow fall, but we know very little else: e.g. how do falling droplets or particles aggregate, how does the resultant object descend, what if the marine snow is eaten by bigger fish etc. I'll present our ongoing experiments on this problem.
