What is the shape of a soap bubble?

A bubble is made of transparent water enclosing transparent air. However the soap film is as thin as the visible light wavelength, resulting in interferences. This creates iridescence which, together with the bubble’s spherical shape and fragility, contributes to its magical effect on children and adults alike.
