Hand Crank Wheel System to Run Propeller – Simple DIY Mechanism!


In this exciting DIY project, we demonstrate how a simple hand crank wheel system can be used to power a propeller without any battery or motor directly connected to it. This fun and educational setup is perfect for science enthusiasts and kids looking to understand basic mechanical energy transfer.

The mechanism uses two yellow plastic wheels connected to a hand-cranked gear. As you rotate the handle, the wheels spin and create rotational energy. A thin wire or string connected to the wheels then transfers this motion to a small propeller, causing it to spin.

This project is a brilliant example of converting manual energy into mechanical motion. It shows how wheels, gears, and simple transmission can work together to perform useful work without the need for electricity.

Such experiments help children grasp fundamental physics concepts like rotational motion, torque, and mechanical advantage. It’s ideal for school science fairs, home experiments, or just as a creative weekend activity.

All the components used in this setup are easily available and low-cost, making it accessible to anyone. The entire system is assembled on a cardboard base, making it lightweight and portable.
