The sight is remarkable. The Solar Balloon gains buoyancy when the air inside is heated by the sun's radiation. Just like a hot air balloon, when heated, the air inside the solar balloon expands - its low density compared to the surrounding air allows the balloon to float.
A powerful demonstration of buoyancy, convection, thermodynamics and solar power. It also teaches Bernoullis Principle and Pascals Principle. This giant sized science demonstration is great for engaging during science class, at a science party or fair. It's so much fun!
