Explore Nook Wooden Waterways lets children design and build their own water channels, then observe how water flows through different wooden patterns. The set includes 9 patterned channels, 3 wooden funnels, and 9 adjustable blocks to modify heights and angles. Perfect for collaborative problem-solving and learning about water conservation. The channels also work with marbles for extended play. Suitable for ages 3+. Designed by an Australian early childhood educator and crafted in Vietnam. Note: Natural timber requires regular maintenance—sand and re-oil as needed, dry after use, and store under cover to preserve longevity.
