Tinkering Studio coordinator Bruce Gemmell will share his knowledge of building bridges. Learn the history and nature of bridges, the integral concepts underlying their construction, and the various types of bridges in common uses today. Challenge Saturday (September 28) will culminate in two visitor contests: first an ultimate strength challenge to see whose bridge will support the most weight; second to explore the ratio of strength to load-bearing capability, or whose bridge can support the most times its own weight. Activities included with admission.
