An Education Device is presented for the classroom presentation of one single self-contained impulse, generated within an isolated system, having a substantial observable and verifiable impulse magnitude. The self-contained impulse is generated from a magnitude of spring loaded potential energy performing work on an inertial fulcrum arm structure rotatably suspended within a carriage and bearing upon it multiple inertial mass components in unequal pre-determined spacing. The work of the spring is causing a complex combined rotational and linear motion of the fulcrum arm-carriage structure involving the Hyugens-Steiner theorem. The potential energy magnitude of the spring is distributed into each inertial mass component according to each component mass moment magnitude The fulcrum arm structure is furthermore including a ballistic barrel containing a slidable impulse transfer bolt. An additional flywheel is mounted concentrically onto the final center point of gyration of the fulcrum arm structure for collapsing the acquired momentum magnitude of the fulcrum arm to zero, in a mutual reciprocal inelastic collision. The inelastic collision allows the continuation of the transfer bolt momentum to proceed within the ballistic barrel causing it to collide with a boundary of the isolated system of the device, accordingly propelling the device in a substantial observable longitudinal motion.
