The four wheels of an air-powered car have no power. Its power comes from the thrust generated by the high-speed rotation of the propeller to push the car forward. Propellers are used in many places in life, such as home fans, air condititioners, range hoods, radiators, unmanned aircraft, wind turbines, ships and so on. This car is a great way to help demonstration motion, forces, basic electricity, transportation, air propulsion etc.
