Description: Yes, there's a serious side to this big bag of wind. It will help your class learn the properties of air and air pressure and the principles of density and buoyancy as affected by heat. After mere minutes in the sun, the air in our huge plastic bag expands enough to lift into the sky. Inflate it further by running, then tie off the ends and watch the bag rise silently. 50 feet long and 3 feet in diameter, it's as big as you can get. Can be cut into several smaller bags. Includes: instructions with class activities and student worksheets. You need string or line.
