In this Demonstration, the macroscopic behavior of the contact line during spontaneous spreading of a nonvolatile droplet on a substrate is studied. A droplet is placed on a substrate and initially makes contact with the substrate at some nonequilibrium contact angle . The drop then begins to spread until it reaches its equilibrium contact angle . The dynamics of this process are simulated in this Demonstration.
