Spring Unit
For showing conversion of potential energy stored in twisted rubber to kinetic/electrical energy. Elastic bands are looped and stretched between pulley and support. A crank handle and pulley combined with ratchet stop allows the rubber to be wound up and released to drive a dynamo, supplied without dynamo.

Turbine/Pump Unit
This simple unit can help the student understand the operating principle of pump and turbine. The unit consists of a rotor attached to a pulley via a shaft. It also includes 3 metal nozzles and a stopcock. When driven by a motor, the unit works as a pump, raising the water to higher potential energy. Whereas when the rotor is made to rotate by flowing water, the unit acts as a turbine.

Magnetism
Eddy Current Kit
This Eddy Current Unit is a compact demonstration apparatus used to study electromagnetic induction and the effects of eddy currents. It features a conductive metallic disc mounted on a rotating shaft, supported by a rigid base. An adjustable arm allows the placement of a magnet close to the rotating disc, enabling users to observe eddy current effects such as magnetic braking, resistance to motion, and energy dissipation. It is ideal for classroom demonstrations of electromagnetic principles in a clear and interactive way.
Features:
- Metallic conductive disc
- Rotating shaft with support
- Adjustable magnet holder arm
- Rigid base with labeling
- Smooth rotation mechanism

Wind Power Demonstrator
This wind power generator can be used to demonstrate the generation of electricity by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small LED and a voltmeter. Instructions included.

Hydroelectric Power Station
Ideal for classroom demonstration, this hydroelectric power station model allows students to directly observe the process of conversion of water flow to electrical energy that occurs in hydroelectric power plants. The water turbine is mounted on a plastic base together with a dynamo, newton disc, lamp, LED, and a two-way selecting switch. The switch selects delivering power to either a lamp or a Newton’s Color Disc. The LED can be removed if you instead want to draw current from the 4 mm output terminals. Includes instructions.

Hero’s Engine
Hero’s Engine demonstrates the principle of jet propulsion. The apparatus consists of a small Erlenmeyer flask with a rubber stopper and two tubes with tangentially oriented jets. A collar is provided around the flask to hang it above a heating source. When water boils inside the flask, steam escapes the jets and the flask spins.
