STEAMagination™: It’s the connection of STEAM (science, technology, engineering, arts & math) with a child’s natural curiosity and creativity and it powers the fun of each and every K’NEX® building set. Building with K’NEX puts children on a path towards a fundamental understanding of STEAM/STEM subjects.
Requires 2 "AA" batteries, not included.
