Smithsonian Motor-Works

Smithsonian Motor-Works Kit is a transparent, hands-on model engine that brings mechanics to life. Designed for curious learners ages 8 and up, the kit includes over 100 parts that screw together to form a working, battery-powered four-cylinder engine. Watch the spark plugs fire, valves rock, and pistons move—thanks to built-in lights and sounds, all visible through its clear casing. This immersive STEM-building experience naturally enhances understanding of mechanical systems, energy transfer, fine motor skills, and scientific curiosity without screens.
