Kick-start an interest in mechanical engineering with the Smithsonian Motor-Works Kit — a hands-on STEM activity that lets kids build a functioning model engine from the inside out. Following step-by-step instructions, young engineers assemble cylinders, pistons, gears and ignition components to create motion just like a real internal combustion engine.

Once complete, flip the switch and watch the engine come to life as the pistons fire in sequence — with light effects that simulate spark plug ignition and a clear viewing chamber so kids can observe every moving part. Along the way, they learn how engines generate power, why timing matters, and how machines keep our world moving.

Perfect for science fairs, classroom demonstrations, homeschool lessons or simply weekend building fun, Motor-Works encourages confidence and curiosity through meaningful hands-on exploration. Smithsonian educational quality ensures a kit that both entertains and teaches lasting STEM concepts.

• Care Instructions: Store all components in a clean, dry place and keep smaller pieces in labeled bags or containers to prevent loss. Use included tools, chemicals or materials exactly as directed and under adult supervision when required. Wipe surfaces and reusable parts with a dry or slightly damp cloth after use; never submerge electrical or sensitive components in water. Dispose of single-use materials responsibly after completing experiments. Keep kits away from heat sources, open flames and direct sunlight. Wash hands after handling science materials or experiment elements. For multi-session projects, label progress and store unfinished builds safely to protect components.
