Anyone who thinks that marble runs are only for children will be pleasantly surprised here. Star Coaster is a brilliant, spectacular marble roller coaster featuring outrageous descents over breathtaking steep sections, through loops, and rapid curves. It's a serious challenge for young and adult tinkering fans, 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 a demanding marble run is constructed using metal elements, flexible plastic tubes, switches, seesaws, and rotating arms, allowing the included metal marbles to 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 immense fun: it can take anywhere from several hours to several days, depending on the level.
