Make this 50-foot bag rise high in the air, simply by filling it with air and letting it warm in the sun. What a great science fair experiment! Thermodynamic energy at its best.
The Solar Bag™ measures 50 feet long and 29 inches in diameter. Simply fill with air by running, tie off the ends, and let the solar energy of the sun heat the air inside the bag.
Within about five minutes, the bag will rise into the sky.
(Polybagged with Activity Guide. String not included.)
