This is a bridge that Michael and I built and tested in our high school engineering class. Overall it had a mass of 85 grams (0.19 lbs) and held 202 lbs. We used wood glue to connect the pieces of balsa wood. Restrictions: - No more than two pieces of balsa wood could be laminated together with wood glue Thanks to Chris for filming! Tested on 12.13.2010
