Title: Spinodal dewetting under electrowetting

Description: A water drop is spreading in ambient silicone oil driven by electrowetting. The video shows a view of the substrate-drop interface viewed through the transparent substrate. The interference fringes show that an oil layer is dynamically entrapped (in a Landau-Levich-Derjaguin type fashion) by the moving contact line. Subsequently, the entrapped film becomes unstable under the influence of the electric field and decomposes into many drops.
