Uprising sheet during simultaneous droplet impacts —Anjan Goswami (Imperial College London)

Upon simultaneous impacts on a solid surface, the interaction of two spreading droplets generates a central uprising sheet, which grows upwardly and sidewise with a semilunar shape and eventually deposits and/or breaks into secondary droplets. The video shows two perspectives of the sheet evolution at 300x slower than real-time.
