WATCH: Slow-Mo Video Reveals Raindrops On Sand Behave Like Asteroid Impacts.
This amazing video shows the impact of water drops on the surface of granular particles, a phenomenon that is likely familiar to all of us who have watched raindrops splashing in a backyard or on a beach.
The high-speed photography from APS Physics reveals the detailed liquid drop impact dynamics at various impact velocities.
This information allowed them to construct a simple model for describing the morphology of raindrop imprints in a granular bed.
Surprisingly, they found that liquid drop impact cratering follows the same energy scale and reproduces the same crater morphology as that of catastrophic asteroid impact cratering.
