The impact of a water-in-oil compound drop on a dry quartz surface was studied. The impact outcomes depended on a core-to-overall mass ratio and a Weber number. For a Weber number less than 570 and a core-to-overall mass ratio ranging from 0.07 to 0.7, five collision patterns were observed: complete deposition, shell deposition with core partial rebound, shell splash with core-shell deposition, shell splash with core partial rebound, and shell splash with core-shell partial rebound. Past research has indicated that the splash phenomenon depends strongly on liquid properties such as surface tension and viscosity in addition to the properties of the solid surface and the surrounding gas. The liquid properties in a compound drop were made non-uniform by the presence of additional interfaces in the interior of the liquid drop.
