Watch our giant solar tube gently lift into the air. Simply run to fill with cool air, tie off the end, and move it into the sun. As the tube heats, the air expands and becomes less dense. Then the Solar Tube begins to float! At 60 feet long, this lightweight, black plastic tube is the largest Solar Tube available, 10 feet longer than any solar bag on the market! Perfect for teaching density, buoyancy, solar energy, and Charles' Law. Can be easily cut into three twenty foot tubes. Includes: Solar Tube, string, and instructions.
