Adjust color, motion, to match real soap bubble (inset) Background is my simulation of soap bubble under microscope. Inset is real soap bubble closeup.
Inset: Soap bubble under the microscope. Light reflects on soap bubble inside and outside surfaces. Those two rays interfere. Thickness of the bubble film determines the wavelength (color). Light with a certain wavelengths (colors) are amplified. Thus, different colors in the inset movie correspond to different film thicknesses of the soap bubble. (The movie is from Alexander Klepnev's soap bubble closeup on Wikimedia Commons. Background is my simulation).
