Totally reengineered, our mousetrap-powered boat is now faster and will travel farther than ever before. With its slick new hull design, the boat glides across the surface of the water with minimal friction. The kit can be built for distance or speed, and the assembly time is between one and two hours for most students. Finished kit is 4" wide and 18" long. Requires glue, long-nose pliers, drill, and hobby knife.
