Soap Bubbles in Space
While aboard the International Space Station, astronaut Don Pettit took some time off to experiment with soap bubbles and films. This NASA Web page presents the surprising and startling results of his soapy ventures in a zero-g environment. Go to: http://science.nasa.gov/headlines/y2003/25feb_nosoap.htm
