Activity uses very inexpensive materials—foam board, a pop-up bottle cap, and a balloon—to teach design and testing procedures. Includes background information on engineering processes and detailed instructions. This project appeared in the August 2011 issue of Tech Directions. It has been reformatted for easy classroom use and also includes a grading rubric, drawings, and additional photos.
