In this paper an experimental study is presented to investigate the dynamic behavior of impacting droplet onto a liquid film. The main parameters are the droplet velocity and the thickness of the liquid film photographic images are presented to show the formation of crown, height, central jet height and the size of disintegrating droplet from the central jct. The diameter and height of crown height of crown are higher for faster droplet and thinner liquid film. On the other hand, the height of cen-tral jet are higher for faster droplet and thicker liquid film. The size of disintegrating droplet from the central jet heavily depends on the droplet velocity; Larger droplet is produced with faster falling droplets.
