Hook the rubber-band on the knob on the dowel between the back wheels. Turn the wheels backwards to tighten the rubber-band. So the rubber-band doesn't come unwound, hold the wheels and car to set down on the floor. Let go and watch it take off!
The rubber-band car has a finish with a non-toxic mineral oil rated for food contact. This is a child-safe finish that preserves the natural wood feel of the simply designed and sturdy toy. It measures about 7" long and 5" wide at the back to 2" wide at the front.
