This is a plastic marble-run construction kit with 10 bases, 55 action pieces and 135 smooth-run tube pieces, plus six colored marbles and a UV light that adds a glow effect to the track. It is aimed at kids 7 and up and leans on hands-on gravity experiments rather than step-by-step model building. Compared with classic fixed marble runs, it offers more open-ended layout freedom and a light feature rivals usually lack, but the pieces are small and the box is compact, so big builds are limited. It suits patient builders who like testing and reworking a track.

This STEM marble run set lets kids build their own tracks and watch marbles roll through them. It includes 10 bases, 55 action pieces and 135 tube pieces, which can be arranged into different layouts.
Six marbles in different colors come with the set for testing each run. A UV light adds a glow feature during play, and the batteries for it are included. Building and testing the tracks explores how gravity works.
