A soap bubble is a very thin film of soapy water that forms a sphere with an iridescent surface. Soap bubbles usually last for only a few moments before bursting, either on their own or on contact with another object. They are often used for children's enjoyment, but they are also used in artistic performances. Soap bubbles can help solve complex mathematical problems of space, as they will always find the smallest surface area between points or edges.
