Slide-Maker Marble Run
Design possibilities are limitless with this 68 piece marble run. It's made of sturdy, colorful plastic that's easy for younger kids to use and includes 12 marbles to run through the flippers, funnels, ramps, twists, and into the catch-all hoppers at the bottom. It will take quite a while for your kids to get bored of redesigning their marble run and watching the marbles travel through their creations. If you want to build even bigger marble runs, check out the Accessory Set with 36 additional building pieces (spirals, wheels, funnels, and cylinders) and 6 marbles.
