By changing the size and velocity of the drops, using water, and utilizing water-ethanol and water-glycerin with different volume concentration, we probed into those factors influencing the steady size. It turns out that along with the increase of the size or velocity, the max-dilated radius will rise; however, the contact angle of the droplet and flat surface will decrease due to the increase of both. Furthermore, in terms of the different volume concentration, when the content of ethanol gets more, the max-dilated radius of drops to the rate of the change of the velocity will increase since the size expands. Nevertheless, as for water-glycerin, the more the contest of glycerin is, the max-dilated radius will be more closer to 1.5 times size of the droplet before crashing.
