Surface tension and zero gravity.

Surface tension is the force that causes drop of liquid turn into a sphere in conditions of zero gravity (free fall). We can only observe this effect for a fractions of a second when we watch raindrops or water running from a tap.

When falling drop hits the water surface it behaves like an elastic trampoline. It bends in then springs throwing drop back in the air. It's good time to take the picture.

For this picture we used glass of milk. We shot it in the bright sunny day to achieve maximum illumination and used extremely short shutter speed to "freeze the time" as much as possible.
