Smithsonian Motor Works Engine Kit

Engineers-in-training, start your engines! 

With this hands-on kit, kids build their very own working 4-cylinder engine—then flip the switch to see it come alive. Spark plugs light up, pistons pump, valves rock, and the whole engine turns just like the real thing.

Perfect for curious minds, the included STEM poster breaks down how internal combustion engines work and teaches the four essential cycles in a fun, easy way.

What Makes It Challenging:
• Realistic working engine model
• Moving pistons, rocking valves & firing spark plugs
• Light-up, battery-powered action
• Encourages STEM learning
• Ages 8+ (batteries not included)
