The Knex Dragon Revenge Roller Coaster develops your child's skills through having fun. Creative builders can make a real working roller coaster complete with a burning castle and motorised 'flying' dragon. The set includes over 650 parts with K’NEX rods and connectors that snap together easily with a satisfying 'click”', plus a coaster car and track. A motorised chain lift sends the coaster car screaming through twists and turns, past the ferocious dragon, through the burning castle and back to safety! 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. Easy-to-follow instructions are included for a frustration-free building experience.
