Caption: "Animation of a water drop falling from a tap. The animation consists of 18 individual images, out of a series of about 300 images. The animation is not a series of the same drop, but different pictures of different drops arranged to make them look like a series of pictures of one drop." (Slightly edited.)

An illustration of fluid dynamics (AKA hydrodynamics).
