Despite popular representations, raindrops are not shaped like teardrops. Small raindrops start out being round. As they collide with other drops and grow in size while falling, however, they begin to flatten, taking on a shape that is more akin to a hamburger bun or a bean. Some raindrops eventually break apart, assuming an arch-like shape during the division process. Raindrops typically divide into smaller drops when they grow to a radius of 0.17 inches (about 4.3 mm).
