Soap bubble turbulence: Rainbows spin on the surface of a bubble

Watch more with these video collections:

The soap film is a half-bubble of about 7 cm diameter on the top of a plastic glass. The system is illuminated by light diffusing from the bottom of the glass. The camera is placed on one side of the bubble and what you see is the internal surface of side opposite to the camera. Turbulent motion is induced both from the heating of the light and from the motion of the air around the bubble.
