Galt Toys Marble Run consists of 24 brightly coloured pieces in 4 different shapes (chutes, tubes, curves, bases) to build together into a marble run, plus 6 marbles. An intriguing and fascinating construction set! Children can create small, simple marble runs or more complex structures with the colourful slot- together plastic pieces. The marbles will disappear inside the columns, roll down the chutes, through the curves and tubes. Building a variety of challenging marble run structures will provide many hours of fun. Children will enjoy devising a variety of routes for the marbles to roll along as they descend to a home base.
