Introduction • You have been hired as a mechanical engineer to work as team member for a company called Matercraft Watersports Design, MWD. This company manufactures a variety of different boat designs. In a recent partnership with the town of Blacksburg, MWD has acquired an abundance of recycled materials. They are starting a new project in which these recycled materials will be used for an innovative boat design.
Challenge • Your task is to use the technological design process to invent a scale model of a self-propelled boat that can transport materials back and forth from Conrad Brother’s Marina to Rockhouse Marina.

Materials • Recycled Soda bottles (a variety of sizes and shapes) • Recycled Styrofoam • Recycled Plastic Containers • Old CDs • Rubber bands • Ping-pong ball (to transport only) • Hot Glue • Scissors
Limitations • The boat must transport a ping-pong ball a distance of five feet in at least 30 seconds. • Your boat cannot be any longer than 10 inches. • The boat can only have one propeller. • Your boat can only be created from the materials listed. Not all of the materials have to be used. • The ping pong ball cannot get wet. • Only one large rubber band can be used to spin the propeller.
