This paper describes a demonstration and explanation of sound absorption in water due to bubbles,and in air due to a fog of water droplets. It is suitable for 10–12 year olds, but the paper indicates where further exploration of the simplifications in the explanations provided for that age range would allow the demonstration to be used for undergraduate and Masters-level teaching. Applications to submarines, the space shuttle, and neutron generators are described. The demonstration is designed for transportation in a family-sized car.
