Bubbles are an incredible natural phenomenon that teach us a lot about physics, geometry, and mathematics. A bubble’s shell is composed of a layer of water molecules surrounded by two thin layers of soap. The liquid shell of a bubble is always pulling inward due to the phenomenon known as surface tension. Water molecules minimize the surface area of the bubble and a sphere is formed; a sphere is the shape with the least amount of surface area while containing volume. Bubbles burst if enough of the water molecules evaporate or if anything fractures the tenuous layer of water molecules.
