www.SisterZone.com: "SisterzOn Bridges shows how to build an 'Elementary Level' balsa wood bridge. This particular bridge won 1st place at California Region 11 and California State competitions. It also won 3rd place at the 'Destination Imagination' Global bridge building competition in Knoxville, Tennessee in May 2005. It is especially useful to kids who want to understand the process of building balsa wood structures."
