Ignite the joy of learning while playing with this Robbie Toys V8 Engine, a kit to assemble a V8 internal combustion engine model. The engine includes over 270 parts to reproduce the 4-stroke cycle: the eight pistons move up and down, just like in a real V8 engine. The model has a battery-saving system, as it will run for 30 seconds before turning itself off and also features realistic lights and sound effects. Complete instructions that explain how to assemble the engine, the 4-stroke cycle of car engines, what happens within the model when the start button is pressed, and why it is called a V8 engine are included in the 28-page full-colour booklet. The set requires three x AA batteries, which are not included. Suitable for ages 10 and above.
