The soap bubble is a very thin film of soapy water surrounding the air that forms a hollow ball with the iridescent surface. Soap bubbles usually last only a few seconds before they burst, either alone or in contact with another object. They are often used for children’s enjoyment, but are also used in artistic performances. Assembling several bubbles leads to results in foam.

When the light shines on a bubble, it appears to change its color. Unlike observed in a rainbow, arising from differential refraction, the colors visible in the soap bubble are due to light disturbances reflecting the front and back surfaces of a thin soap film. Depending on the thickness of the film, different colors interfere constructively and destructively.

Soap Bubble Uses in Art

The performance of soap bubbles combines entertainment with artistic achievements. They require a high level of skill. Some performers use commercially available bubble liquids, while others make their own solutions. Some artists create giant bubbles or tubes, often enveloping objects or even humans. Others create bubbles that form cubes, tetrahedra and other shapes and forms. Sometimes bubbles are handled with bare hands. Soap bubbles can be filled with flammable gas, like natural gas, and then ignited.
