Galt's exciting Super Marble Run is super fun for the whole family. Kids will enjoy creating and re-creating fascinating marble runs and parents may even want to get in on the act. The 60 pieces slot together set includes nine chutes, nine curves, 24 tubes, six bases, a staircase, rotary drop, paddle wheel, roundabout and eight marbles. The marbles will disappear inside the columns, roll down the chutes, through the paddle wheel and around the roundabout. Marble runs aid child development in a number of ways.Building a marble run encourages children to use their imaginations and problem solving skills. To construct the marble run, they use both fine motor skills and logical and sequential thinking. Galt toys are designed to meet each stage of a child's development and encourage learning through play.
