Click clack, click clack, there goes another marble down the track. Kids 4 years and up will enjoy building and rebuilding this cleverly designed marble run. The 16 pipes are made from environmentally friendly bamboo-a giant, natural grass-which, when stacked with plastic rings, echo the look of bamboo in the wild. Six bamboo rails create pathways along which 16 brightly colored marbles can roll until they emerge to be corralled in a rope circle, ready for another ride on the rails. A rope and bamboo handle make Scivolino's sturdy box into a great carry-along.
