Since most oils are less dense than water, they do not sink but instead spread out to minimize their potential energy. What appears as a shimmering, iridescent slick is actually a delicate balance of physical forces, where density differences are overcome by surface tension.
Oil on Water Spherical Droplet Formation and Surface Tension Dynamics
The interaction between the dispersant, the oil, and the water is complex, and the stability of the resulting micelles is a key factor in determining the overall success of the cleanup effort. However, this process trades a visible surface slick for potentially more damaging subsurface contamination.
Variability of the Pattern The specific colors and patterns seen are highly dependent on the thickness of the oil layer, which varies dramatically across the slick. Areas where the film is incredibly thin, approaching the molecular scale, will appear dark or black because the destructive interference cancels out most visible light.

This interaction governs how the oil spreads, how stable it remains, and how it colors the world above it. This tension is also responsible for the shape of the droplets, favoring spherical forms that minimize surface area.
