This amazing solar bag can be used to explore both simple scientific concepts related to solar energy or complex scientific laws of gases! What makes this long (50 feet long!), black bag float so high in the air?? When the bag is filled with air, the sun heats up the gas molecules inside, which begin to speed up. Since the heated air inside the bag is less dense than the cooler air on the outside of the bag, the solar bag will begin to float!! Do neat experiments with your students, such as calculating the rate at which the solar bag rises!! Or use the bag to have a discussion on how solar energy works in various technological devices such as a solar collector, calculator, solar-powered car, or a solar pool cover!! Just fill the bag with air and let the sun do its job!! Classic demonstration of what awesome energy is really contained in solar power!!
WARNING: This product WILL float away if you are not careful. It is large enough that you could potentially have a dangerous situation occur if it floats away. We HIGHLY recommend the bag be held onto at all times during the experiment, and to be used only under direct adult supervision.
