K'nex Speed Demon Roller Coaster Overview

Your little daredevil can build the K'Nex Speed Demon Coaster, a new roller coaster building set that stands over three feet tall with over 19 feet of twisting, turning track. The set contains over 625 colorful K'Nex pieces, including a coaster car, motor, chain lift and track.
