An innovative construction set for assembling a spectacular hotrod, complete with working mechanical details: steering wheels and reciprocating pistons. With over 211 components, this kit allows for hands-on experimentation with the principles of mechanics and an authentic STEM experience. The model is designed to faithfully reproduce real mechanisms, transforming the car into a true engineering laboratory. Thanks to the illustrated manual and interactive 3D instructions, children can build the car step by step, learning independently. It is part of Clementoni's new Science & Play Mechanics line, offering larger, more detailed, and engaging models. Mechanics that run fast. A hotrod with wheels, working gears, steering, and pistons that really move. For children discovering a passion for the world of mechanics. Over 200 components... zero boredom! With 211 pieces to assemble, exploring STEM principles becomes a hands-on and exciting game. A laboratory inside a car. The model reproduces realistic mechanical movements: from the transmission to the reciprocating motion of the pistons. Guided, yet always the protagonist. The illustrated manual and 3D instructions make construction clear and stimulating, without frustration. The new era of mechanics, branded Clementoni – part of the new Mechanics generation: more details, more gears, more educational value and fun. Entirely made in Italy.
