Water Blocks

About this product

PlanToys® Water Blocks are colorful, wooden building blocks filled with liquid that allow children ages 3 and up to explore gravity, color mixing, and spatial relationships. Each block contains water sealed within a transparent window, enabling visual discovery as the liquid shifts when stacked or laid flat. Children can experiment with stacking configurations to observe how the liquid moves and blends colors. Made from wood, plastic, and water, these durable blocks are designed for safe, hands-on play and encourage creative exploration and early STEM learning through tactile interaction.
