The K'NEX Motorized Creations Building Set lets kids aged 7 and up unleash their creativity in a whole new way. With 325 pieces including gears, wheels, axles, and an electric motor, young builders can construct working models that really move. Kids can build a Ferris wheel that actually spins, a car that drives itself, or a crane that lifts and lowers - the possibilities are endless. Once the basic build is complete, kids can then experiment with modifications to enhance speed, torque, and movement. The motorized functions bring their imaginative designs to life, boosting engagement and hands-on learning. This kid's construction toy's snap-fit pieces stick together securely and can be easily reassembled into other creations, helping to develop hand-eye coordination, fine motor skills, problem-solving skills, and spatial awareness, while providing an understanding of STEM subjects. Encourage curiosity and creative play with this K'NEX toy construction.
