Oscillations of soap bubbles

Soap Bubbles: Part 1

love soap bubbles. They're beautiful, delicate, and though they live only briefly, it's a glorious moment. They float on the air, brilliant colors wobbling over their surface, and when they pop into nothingness, it's just an opportunity to make more bubbles! This issue and next I'll talk about the chemistry, physics, and computer graphics of soap bubbles. Here I'll focus on the physics of soap ...

Generating Soap Bubbles by Blowing on Soap Films.

Making soap bubbles by blowing air on a soap film is an enjoyable activity, yet a poorly understood phenomenon. Working either with circular bubble wands or long-lived vertical soap films having an adjustable steady state thickness, we investigate the formation of such bubbles when a gas is blown through a nozzle onto a film. We vary film size, nozzle radius, space between the film and nozzle, ...

Capturing the Reflectance Model of Soap Bubbles

We describe a system for rendering bubbles in natural environments using filtered environment maps. The system incorporates the optical properties of soap bubbles such as the interference patterns generated by the film. We describe a mathematical model to simulate the reflectance properties of the bubbles using a bidirectional reflectance field. This BRDF is used to filter an environment map ca...
