The K'Nex Speed Demon Roller Coaster is a building toy for children ages 9 and up. The set includes 625 pieces that are assembled to create a large roller-coaster that sits over 3 feet high. Assembly instructions are included in the box, and feature a step-by-step color coded guide to building the coaster. Once assembled, a motorized chain lift raises the coaster car to the top and the releases it, sending it through the course with the force of gravity. The motor requires 2 "AA" batteries to operate. Over 19 feet of track are in the final build, and more instructions are available from the manufacturer's website for different configurations.
