## Description

Ready For Blast Off! Build a space themed roller coaster! The K’NEX Amazin' 8 Coaster building set lets your creative builder make a real working roller coaster. This set comes with 448 parts - rods & connectors that snap together with a satisfying “click”, plus a coaster car and track. A motorized chain lift sends the coaster car screaming through twists and turns. 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 relations, 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 mini working roller coaster! Easy-to-follow instructions are included for a frustration-free building experience. Requires 2 "AA" batteries, not included.

Review: So much fun! - This was a Christmas gift for our 7 year old grandson that lives in another state. He loved putting it together with his dad and plays with it often!
Review: Made for an excellent club fair display - I bought this to draw some eyes to my theme park club at a college club fair. I cut out a piece of plywood to make a solid base and ziptied the coaster to it. It definitely worked to get a lot of people to come over and listen to our spiel. The instructions were easy to follow and the setup is pretty sturdy. Definitely beats out the crappy knock-off lego model we used to have.
