A milk crown is a very attractive phenomenon. However, it is very difficult to catch a continuous picture. Therefore, there is almost no systematic research. Then, with the digital Video Camera, we took the continuous image and analyzed them. The parameters of the experiment are the velocity of the waterdrops which collides with a thin liquid layer, the depth of a liquid layer, and the viscosity of fluid of the experiment. Surprisingly, we found that crown-like structure at about 10ms to 30ms after the collision of waterdrop expand at the same speed unrelated to the parameters.
