"I can recommend any reader who is not afraid of being late for breakfast to keep a bag of marbles in his bath-room."
A. M. Worthington, A Study of Splashes, footnote on page 121
This animation is assembled from A. M. (Arthur Mason) Worthington's drawings of .15 inch diameter mercury droplets falling from 3 inches onto a glass plate. Some of these were drawn as early as 1876, using a nearby spark for very brief illumination. The thirty drawings (see source scans and references,
from his 1894 book The Splash of a Drop
) are at different phases of the splash, separated by about 1/600 sec., using machines that could repeatably produce a drop and vary the timing of the spark. He refined his equipment and techniques over several decades, eventually moving to photography.
Worthington, a physics professor, wrote and spoke eloquently about his methods, observations, and the physics behind drops and splashes, much of which is summarized in his 1908 book A Study of Spashes
. Its opening line:"The splash of a drop is a transaction which is accomplished in the twinkling of an eye, and it may seem to some that a man who proposes to discourse on the matter for an hour must have lost all sense of proportion."----------------------
