Unhinged Structure
I, II, III & IV

The problem is to design and build a solution using only balsa wood and glue that folds into the team's structure without coming apart. The team may use material other than balsa wood and glue to serve as a hinge. The team will test its "folded" structure by placing as much weight as possible on it during a performance that also includes three different objects that change appearance by being folded or unfolded. Cost limit: $145 USD.
