Letter: Dome-shaped splashes generated by the impact of a small disk on a sessile water drop

We investigate experimentally the splashes arising from the impact of a small solid disk on awater drop resting on another disk of the same diameter. The impact leads to an impulse radial ejection of water from the gap between the rapidly approaching disks. We revealed that the splashes have a complex spatial shape, which is a consequence of increasing liquid ejection velocity with time. Published by AIP Publishing.
