The purpose of the science project of sound-waves extinguishing fires in zero-gravity is to help put out fire in spaceships and the space station in outer-space. The hypothesis of this project was that sound-waves from a stereo would be able to put out a fire. The procedure that the scientists took was to light a candle surrounded by activated stereos to see if it would extinguish the fire. The results were that the candle was put out in their lab, but it wouldn't work with a very large fire. In conclusion the hypothesis was correct and the sound-waves extinguished the flame.
