Fill the UFO Solar Balloon with air, attach the line and watch it magically rise. Bright direct sunlight warms it in a few minutes and it soars! But how does it work? 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. Solar balloons have been proposed for exploration on the planet Mars, as well as many other scientific uses. The UFO Solar Balloon makes an excellent gift for young and old alike. This educational toy is great for summer fun in the sun, an awesome stocking stuffer and even a winning science project!
