Hello! Wooden marble walkways are truly an amazing combination of creativity, craftsmanship and physics. They are made up of wooden paths, ramps, and blocks that allow you to build intricate structures that the balls can navigate through. As the balls roll down the lanes, you'll witness a mesmerizing display of gravity, momentum, and cause and effect. Some kits may require some precision and problem solving, but overall they are designed to be easy to use and fun for kids and adults alike.
