A team of researchers affiliated with several institutions in China has found a way to force liquid drops to spiral as they rebound after landing on a manipulated surface. In their paper published in the journal Nature Communications, ...
Falling droplets bounce as many as fifteen times before they come to rest on a flat surface. In the past, it was believed that this phenomenon is limited to water drops on superhydrophobic surfaces.
