The Realistic V8 Model Engine is a fun and engaging way to learn about auto mechanics. Once assembled, a simple press of a button turns on the power, spins the cooling fan and makes the pistons fire up and down. Flickering lights mimic the air-fuel combustion process, while the engine roars with authentic sound effects. Contains more than 250 pieces, plus an easy-to-follow instruction book with fascinating facts about V8 engines.
