This video explores the dynamics of liquid droplets impinging on superhydrophobic surfaces. Theses surfaces represent radical departure from conventional smooth surfaces. The way these surfaces interact with liquids (droplets, streams, puddles, etc.) is important in applications such as self cleaning surfaces and glass, anti-icing surfaces for airplane wings, drag reducing surfaces, etc. The present research shows that the dynamics of impinging droplets is influenced by viscosity to a much greater extent than previously thought and the visualization reveals fascinating dynamics and images.
