Air as fuel. It's an alternative to petroleum. Air is available 24/7, does not run out and it's free. OWI's Air Power Racer can break down this technology to its simplest form. This is an amazing kit that uses a vision from the beginning of the Industrial Age in the middle of the 19th century. Now, your child can bring that vision to life and gain valuable insight into compressed air propulsion. Assembly and operation is a breeze. A pump-up bar with a pressure meter is built into the car for simple operation. The meter measures the pressure of compressed air. The air chamber made from a PET (polyethylene terephthalate) bottle. Red silicon tubes create an air tight fit. A safety valve is included in the assembly. If the user keeps pumping while the tank is full, the safety valve will open and bleed the air automatically. When the air chamber is full, you can release the compressed air; the air then expands and drives the vehicle a distance up to 50 meters in 35 seconds. The car is fast and furious fun that requires no batteries or specific weather conditions to limit its usage. OWI's Air Power Racer is not only designed with the environment in mind, but is also fun and easy to build! The polyethylene terephthalate (PET) bottle is recyclable.
