Hang the weight and watch as the fall turns gravitational energy into light. A great hands-on physics demo kids understand instantly.
Turn the crank to produce electricity with your own power. The transparent body shows the gears at work in real time.
The mechanism is fully visible: colorful gear wheels and a dynamo clearly demonstrate the conversion of energy into light.
Discover the principles of mechanics and electricity in a fun way. This clever experimental kit uses a hand generator or gravity drive to light a bulb in a transparent body with visible gears. Ideal for home experiments, school projects, and eco-friendly inspiration.
Thanks to the clear casing, you can see exactly how the gears and dynamo work together to produce energy. The kit develops logical thinking, fine motor skills, and children’s natural curiosity about how the world works—without any batteries.
