- Vacuum Cleaner
- Propeller Plane
- Solar Powered Fan
Project Line: Engineering
Vacuum Cleaner - A vacuum cleaner uses an electric motor that spins a fan and creates a region of low pressure inside its pipe, and the outside air pushes dust and dirt into the pipe.
Propeller Plane - Propeller produces lift in a forward direction, a force we refer to as thrust. Its rotary motion through the air creates a difference in air pressure between the front and back surfaces of its blades. This pressure difference pushes the plane forward.
Sun Powered Fan - Fans work by moving air, allowing your skin to evaporate sweat faster, and cooling your skin. Solar powered fans harness sunlight to generate electricity to power the motor.
