A solar balloon is a balloon that is filled with air and gains buoyancy because the air inside the balloon has been heated by radiation from the sun. The black balloon material absorbs the heat of the sun’s rays, causing the air inside the balloon to expand and reduce in density compared to the air outside of the balloon, giving it buoyancy. This balloon functions just like a hot air balloon, with the sun acting as the heat source. The UFO Solar Balloon makes an excellent gift, and is highly recommended for the classroom setting.
