Those who think that marble runs are only for children will be pleasantly surprised. The Star Coaster is a brilliant, spectacular marble roller coaster featuring outrageous descents over breathtaking steep tracks, through loops, and rapid curves. It presents a serious challenge for young and adult tinkering enthusiasts, whose hearts are guaranteed to race. Available in various levels with different sizes and degrees of difficulty, the sophisticated system consists of a base plate on which metal elements, flexible plastic tubes, switches, seesaws, and rotating arms are used to construct a demanding marble run, where the included metal marbles race down at breathtaking speed. The challenge, size, and complexity of the marble runs increase with each level. The absolute highlight: after a thrilling descent, the marble lands in a battery-operated elevator that brings the marbles back up to their starting positions – and the next descent can begin. Even the assembly is both a challenge and a huge fun: it can take anywhere from several hours to several days, depending on the level.
