This engineering educational toy consists of 275 classic parts and pieces that are responsibly made in America at a landfill-free, zero-waste green manufacturing facility in Hatfield, Pennsylvania. The pieces include rods and connectors that are attached to one another to build a fast and furious land rocket replica. It also allows builders to create a Mach speed car by following the downloadable instructions. These models boast ergonomic body style and visible moving parts. You no longer have to look for batteries to operate the vehicles, as the replicas do not require battery power to make them move. Simply push the models and watch them come to life! K'NEX supports key areas of children's developmental growth. As they click the different parts together and discover how the building system works, they're strengthening their hand-eye coordination, fine motor skills, problem-solving skills, spatial awareness, and imaginations! It also enhances the connection of STEAM (science, technology, engineering, arts, and math) with a child's natural curiosity and creativity, as this powers the fun of each and every K'NEX building set. Building with K'NEX puts children on the path to a fundamental understanding of STEAM/STEM subjects. This building set comes with a sturdy box for a hassle-free storage. It is recommended for ages 7 and up. Let your kids unleash their creativity as they make their own designs for open-ended, high-speed fun!
