HQ Windspiration 501923 Star Coaster: Level 3, marble run, construction toy.

Our spectacular ball roller coasters, featuring hilarious descents across breathtaking steep tracks, looping and fast-paced curves, are a serious challenge for youthful and adult tinkering fans. The versatile components create a sophisticated marble run on which the included metal balls float down at a stunning speed and end up in the battery-powered elevator, which brings them back up to their starting position. The construction is challenge and fun at the same time: it can take several hours to several days depending on the level. For level 9 we recommend an academic degree – if possible with a doctorate degree. Age: 14+
