    You're going to need to clarify what "laws of physics" you're meant to pick from. It seems to me "rubber band powered" anything will have stored energy; what laws will apply to transfer of stored energy?

    With the rubber band powered airplane, you could demonstrate Newton's Laws of Motion, construct a free-body diagram, analyze the flight path and calculate lift coefficient, thrust, or find the rubber band, propeller or wing design that maximizes endurance.
