Rain, Rain, Come Today?


Philipp Lenard studied the shape of raindrops in 1898. His research dispels the common belief that raindrops are 'teardrop' shape. According to his findings, small raindrops are nearly spherical, but larger ones become increasingly flattened on the bottom, like hamburger buns. Very large raindrops are shaped like parachutes.

Makes sense. The air resistance increases as the raindrop gets larger, and the greatest concentration would come in the center, as it gradually has less and less places to escape. Still, not something I'd ever thought of before. Very cool.
