The Solar Balloon uses solar energy to heat air inside the balloon, making it rise.
The balloon measures a whopping 10 feet long with a 2 foot diameter, and includes 60 feet of string, and instructions.
Solar Balloons have been proposed for exploration of the planet Mars, as well as many other scientific uses. How will you use it?
