Build an entire amusement park out of a single box! The K'NEX amusement park in-a-box building set includes a working Ferris Wheel, swing ride, and roller coaster that you can build all at the same time in a fun new miniaturized scale. The set comes with 378 parts, including micro K'NEX rods and connectors that snap together with a satisfying click, plus a coaster car, coaster track, Ferris Wheel seats, and so much more! There are 2 battery-powered motors in the set, including a brand new high-speed blaster motor that launches the coaster car around the track, through twists and turns and back again! Perfect for builders ages 7 and up, K'NEX supports key areas of a child's developmental growth, like fine motor skills, manual dexterity, and spatial awareness, putting them on a path towards greater understanding of STEM subjects. But they won't know that they're learning; they'll be having too much fun building their own working amusement park! Easy-to-follow instructions are included for a frustration-free building experience.
