Bridge is a build event with the goal of building a bridge that is light and able to support the most weight. For this event, you must submit a design log with a variety of things. More details on the design log can be found in the rules.
Tips: Balsa wood is the lightest wood, and wood glue is very strong. Triangles are the strongest shape. Use the previous three to create a bridge for optimal results. You can buy balsa and wood glue below, and there is a website with tips as well. You can mix balsa with other woods, such as basswood, to make your bridge stronger.
It is suggested to make as many bridges as possible and log the designs before you test them so that you can experiment and determine which one is the strongest. The coaches will provide anything that you need to test your bridge, but you may also buy supplies to test it yourself at home.Â
Eye protection is required for this event. Please check the link below for eye protection details.
