The focus of the experiment is to observe the interaction between liquid crystal molecules and solids during the collision and expansion of liquid crystal droplets on various surfaces, resulting in different arrangements of liquid crystal molecules, which are discussed by measuring the static contact angle of the droplets. We intend to know the correlation between the liquid crystal droplet and various surfaces. If there is a solution on the glass slide, the liquid crystal molecules will align parallelly after the liquid crystal droplet hits the surface. The liquid crystal molecules align homeotropically to the surface on a completely dry surface.
