You don't need petrol to go far. Speed through the streets in your air-powered car. Ever wondered if a car could run on air? Well, now you can build one. This project includes all the elements required to build an air-powered car, air-pump and lock-and-raise tracks to play with.Children have to assemble the car and the track as per instructions. Once assembled, children can pump air from the included air-pump, and use the track with lock-and-raise mechanism to understand the effect of friction, incline and propulsion on the movement of the car.
