Bubbles

Bubbles are pockets of gas trapped within a liquid, forming a sphere due to surface tension which minimizes surface area. Commonly seen in soap solutions or carbonated drinks, they reflect light and often pop when they contact surfaces. Bubbles are stabilized by a thin film of liquid that coats the gas, balancing forces between pressure from the gas and surface tension of the liquid. Their size, shape, and behavior depend on factors like liquid viscosity, gas type, and environmental conditions. Bubbles are fascinating examples of physics, showcasing how forces work together to create transient, delicate structures.
