Our Freestanding Water Wall is designed with moveable troughs (6 short and 2 medium lengths provided), allowing you to attach them to the grid wall to change the water flow. It also includes a water pump to send water to the top of the wall and a large trough. Just fill it with water, and children will enjoy hours of fun, especially on a sunny day. While the Water Wall provides entertainment, it also serves as an educational tool. Children begin to understand how water flows, how trough angles affect water flow, and they start developing their knowledge of math and science.
