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.
