Anyone who thinks that marble runs are just for children will be proven wrong here. The Star Coaster is a brilliant, spectacular marble roller coaster featuring dizzying descents over breathtaking steep tracks, through loops, and rapid curves. It poses a tough challenge for teenage and adult tinkerers, guaranteed to make their hearts race. Available in various levels with different sizes and difficulty degrees, the sophisticated system consists of a base plate on which a challenging track is constructed using metal elements, flexible plastic tubes, switches, seesaws, and rotating arms. The included metal marbles speed down at breathtaking velocity. The challenge, size, and complexity of the marble runs increase with each level. The real highlight: after a thrilling descent, the marble lands in a battery-operated elevator, which transports it back to the starting position—ready for the next ride. Even the assembly is both a challenge and great fun at the same time, taking anywhere from several hours to several days, depending on the level.
