For instance, the purple bubble uses a chemical called crystal violet lactone. After the bubble pops, the colored splatter disappears with friction, water or exposure to air. In a normal soap bubble, surfactants reduce the surface tension of the water and allow the bubble to form.

Soap bubble - Wikipedia
Soap bubbles are physical examples of the complex mathematical problem of minimal surface. They will assume the shape of least surface area possible containing a given volume. A true minimal surface is more properly illustrated by a soap film, which has equal pressure on both sides, becoming a surface with zero mean curvature.
