Solar Balloon - Kids Science

The black surface of the Solar Balloon, once you fill it, acts as a solar collector. It heats the air until it expands and is lighter than the surrounding atmosphere, causing it to rise like a hot-air balloon.

Solar balloons works best in direct sunlight when air temperature is somewhat cool, with little wind.

Makes a great school or science project!
