A Solar Bag is a http://www.SteveSpanglerScience.com product consisting of a long plastic bag made from a very thin plastic and colored black to absorb solar energy. The heated air inside the bag provides buoyancy and causes the bag to float. Over the years, it’s become a very popular science demo for teachers to share with their students as they explore the properties of air.
You can imagine how surprised we were to learn that scientists from Pioneer Astronautics and Jet Propulsion Laboratory conducted successful tests of its Mars solar balloon inflation system using our Solar Bag. This video give you a bird’s eye view of what our Solar Bag looks like at about 120,000 feet above the Earth.
