Inspire the next generation of engineers with the "Junior Engineer" STEM building set! This 125-piece construction kit allows children to build 5 different motorized models, including a crane, a Ferris wheel, and a spinning fan. The set introduces fundamental engineering concepts like gear trains, pulleys, and mechanical motion through hands-on experimentation.

The battery-powered motor box brings creations to life, adding an exciting dimension to building. With easy-to-follow, pictorial instructions, kids aged 6+ can build independently while developing critical thinking, problem-solving skills, and fine motor coordination. All pieces are made from high-quality, durable plastic that's compatible with other major construction sets, ensuring years of creative, educational fun.
