Brand: Invento. MPN: 231-5. A ball roller coaster for experienced professionals who are interested in accepting ultimate challenges. Who ever thought that ball roller coasters are just for kids is taught better by Star Coaster. Star Coaster is a spectacular ball roller coaster that guarantees high-speed action rides consisting of wild rotations, daring loop-the-loops and spectacular swivel motions. These ball roller coasters are an ultimate challenge for teenagers and adult enthusiasts alike. Available in different sizes and with different levels of difficulty. The sophisticated system consists of 1 base, on which a challenging ball roller coaster is constructed of metal elements, flexible plastic pipes and switches. Size and complexity increase with each level. The absolute highlight: after a fast action ride the balls land in the battery-powered elevator that brings them back up to their starting positions. The construction of our Spacerails is so much fun and a huge challenge at the same time! Depending of the level, construction can last from several hours up to several days.
