Inertial cars

Inertial cars

— a machine equipped with an inertial engine.

There are two types of these engines. The first one is based on the flywheel: you need to "carry" the car with your hand so that the spinning wheels spin the flywheel, and after that the toy, thanks to the supply of rotation, can travel some more distance — though quite a bit. The second option is an engine with a spring or another similar system that starts by pulling the machine back; when released after the factory, such a machine “shoots” forward and can travel a fairly long distance (several metres) at a decent speed. Anyway, the inertial system is usually more interesting for a grown child than a conventional machine without additional devices.
