soap bubble physics

Soap bubble physics involves the balance of surface tension, gravity, and air pressure. The thin soap film’s surface tension minimizes its area, creating a spherical shape that evenly distributes the internal pressure. When air is blown into the bubble, pressure forces the film outward, but surface tension resists this, resulting in a stable sphere. The iridescent colors come from light interference within the soap film. External factors like gravity and air currents influence the bubble’s shape and lifespan. Ultimately, the bubble’s structure is a delicate equilibrium between these forces, maintaining its form until it pops due to film thinning or disturbance.
