When the water is first poured into the disc, it condenses into patterns that resemble interstellar clouds of gas, but soon it contracts into precise spherical droplets, alive and trembling, which in turn become increasingly homogeneous, covering the entire surface of the disc. The water in the disc both influences the total equilibrium and is influenced by it, exerting an effect on the movement of the balls.
