The Mechanical Effect Demonstrator is an excellent tool for teaching students in a visually and kinesthetically effective manner about power and energy exertion. Kinetic energy exerted by cathode rays (streams of electrons moving from a negatively charged end to a positively charged end of a vacuum) is demonstrated by the rotation of the metal blades inside the bulb.
