Smithsonian Motorworks Engine Kit

Make a working internal combustion engine with this educational Smithsonian Motorworks science kit!

Discover how a real working battery-powered four-cylinder, four-stroke gasoline engine works as you assemble this unique see-through working model engine. With this kit, curious learners can make real lights and sounds; a small electric motor rotates the crankshaft so you can see everything work. This Smithsonian Motorworks kit provides a fascinating way to learn the basics of how a typical car engine runs! 

This kit includes a 35" x 23" color poster with detailed instructions; expand the 'Contents' tab below or a complete list of included items. Please note that the motor color may vary, and that you will need to provide two AA batteries, scissors, and a screwdriver (not included).
