- This image is a high-resolution computer simulation of the head-on collision of two tiny drops, one moving up and one moving down. The drops approach each other with a high velocity, so there is considerable energy in the collision. For more information, see this description.
The diameter of each drop is only about twice the thickness of human hair. Imagine how hard it would be to do this experiment and see what actually happens.
Also, compare the image at left with the simulation above: Note how the edge of the disk and film break up into drops in a similar way.
