Raindrop-formed ‘sandballs’ that erode hillsides tenfold
High-speed images of raindrops rolling on a sandy slope, forming peanut-shaped sandballs (top) and donut-shaped sandballs with hollow centers (bottom).

High-speed laboratory images capture two distinct “sandball” shapes formed when raindrops strike dry, sloped sand and roll downhill. (Top) Peanut-shaped sandballs, where grains coat the surface of a liquid core. (Bottom) Donut-shaped sandballs, which densify into rigid, wheel-like structures with a hollow center, enabling far more efficient sediment transport than splash erosion alone.
