Customer Reviews for K'NEX K'NEX Double Shot Coaster Building Set

Your little builder can create a giant, dueling roller coaster with the K'NEX Double Shot Coaster Building Set. With more than a thousand K'NEX pieces and two contesting cars, this building set not just provides your child the ultimate joy of building a 3.5 feet tall structure, but also lets him experience the adrenaline rush while guessing which car reaches the bottom first. The double shot roller coaster measures more than 32 feet including the twists and turns. Once the motorized chain lift is assembled, all the little engineer has to do is just slide the two roller coaster cars on to their respective tracks and turn the motor on. This motor building set comes with a detailed color-coded instruction booklet.
