The K'NEX Double Doom Coaster has over 891 pieces that create a roller coaster that really works. The classic K’NEX parts including rods, connectors and tube style tracks form a roller coaster track complete with a motorised action that stands over 1 metre high. The coaster is designed to be used with the two cars joined together: it is the weight of the two cars that allow the cars to complete the track successfully. A motorised chain lift is included that requires 2 x AA batteries (not included). The Double Doom Roller Coaster will provide hours of building fun for anyone over the recommended age of 9.
