comment Why sphere minimizes surface area for a given volume?
@DJohnM With the details in this answer, Yes you would need to test all shapes. However, you can in fact write down a hamiltonian for the surface energy and solve that under the constraint of constant volume (technically mass), this will return a sphere.

comment How high will the Ball Jump?
I think you're missing an important factor here: surface tension of the water-air interface. This will result in an opposing force at the moment the ball tries to break the interface which will reduce the height. Additionally, the water-tail that you often see for balls that jump out of the water will increase the effective weight of the ball and reduce its height further

comment How is wind created?
I wonder if there is such a thing as an atomic or molecular level explanation of wind?!

comment Adding a tracer to the surface of a water droplet
If I'm understanding it correctly, you wish to go for a tracer particle technique instead of the mirror technique that @Floris suggested in answer to your previous question. Could you explain your rational? It seems to me that you want your measurement technique to be as non-intrusive as possible, while adding particles certainly doesn't classify as non-intrusive. Moreover, adding particles is probably not even easier to do. Bottom line: I don't see benefits of this method over the mirrors, could you elaborate on your view?

@Hossein If you use a search engine like web of science or scopus you can first do the search and then use refine on article type, where you can select review as the preferred type
