Simply fill with air by running, tie off the ends, and let the solar energy of the sun heat the air inside the tube. Within about five minutes, the tube (which must be tethered with string) will rise into the sky. Absolutely amazing to see, it teaches many scientific principles such as density and buoyancy. The thin, black plastic tube holds over 200 cubic feet of air and measures 50 ft. L x 29 in. dia. A complete set of instructions and a number of classroom activity worksheets are included with the solar balloon.
