Objectives/Goals The objective of my project was to determine the effect of altering the mass and aerodynamics of a vehicle (rocket) on its fuel efficiency. Methods/Materials A pressurized, water powered, bottle rocket was chosen as the vehicle to remove the variables of ground friction and driver's style. After designing the optimal test rocket and establishing the controlled variables--namely the amount of fuel (propellant) and engine thrust (air pressure)--through testing, experiments were conducted to determine the effect of varying amounts of mass and different aerodynamics on the relative fuel efficiency of the rocket as measured by the altitude achieved during each test flight. The effect of mass on fuel efficiency was determined by placing varying amounts of cargo in the test rocket and calculating the altitude that each flight reached. The effect of aerodynamics on fuel efficiency was determined by placing nose cones of varying angles on the test rocket a
