For my AP Physics class, we had to built a boat and race across our pool, given only two large sheets of cardboard and 2 rolls of packing tape.

Using our knowledge of buoyancy and Archimede's principle, we wanted to optimize the volume of the boat that would be submerged in water for maximum buoyancy. However, the boat still needed a hydrodynamic shape to be competitive in forward motion.

My partner, Rachael Kricorian, and I decided to use a fin on the the bottom to direct our path of trajectory, however, we found out that further support was required to hold the boat intact and respond to both compression (caving) forces and tension forces.

As a result, we relied on using a bed of truss triangular structures that Rachael could sit on to serve as a compression response mechanism. In addition, we used the strong longitudinal tension properties of cardboard to keep it from tearing apart.

Result: Our boat was extremely successful and lasted for 3o minutes, having taken 6 different riders! We easily won the competition and earned first place.
