Society has always compared rain to falling tears, which has led to many believing the shape of raindrops to be in a similar shape. In fact, they are not at all. When a raindrop begins to fall it starts in nearly a perfect circle, and then begins to change in shape.
Because of air resistance and speed, the drop morphs into a shape of a flattened bottom with a curved top, or similar to a hamburger bun! Scientists used high-speed cameras to intricately watch falling raindrops, and were surprised at the odd shape the drops form.
