A soap bubble is a very thin film of soap water that forms a sphere with an iridescent surface. Soap bubbles usually last for only a few moments and then burst either on their own or on contact with another object. They are often used as a children's plaything, but their usage in artistic performances shows that they can be fascinating for adults too. Soap bubbles can help to solve complex mathematical problems of space, as they will always find the smallest surface area between points or edges.The bubble's 'skin' consists of a thin layer of water trapped between two layers of molecules, often soap. The surfactant possesses hydrophilic heads and hydrophobic tails. The hydrophilic heads are attracted to the thin water layer and keep the bubble intact. When the hydrophobic tails are disturbed, the bubble pops. It may also burst when it hits a surface.
