It's sink or swim time! In this episode, a master kayak builder challenges the Design Squads to create their own lightweight boats. But here's the catch: their ten-foot-long kayaks must be made out of non-traditional materials. That means plastic pipes and heat-activated shrink wrap. The winning kayak needs to be sleek, waterproof, and stable enough to get paddled through an obstacle course.
