The 3 Tier Aqueduct features three activity tables of varying heights, each equipped with plastic trays. Our Aqueduct bases undergo rigorous testing to ensure they are smooth and splinter-free. Ideal for various mediums including sand and other play materials, the Aqueduct truly shines when used with water. It offers an interactive Sand & Water Play experience, allowing children to connect the tiers using tubes or pipes (not supplied) to transfer water from the highest to the lowest tray.
