This layered waterfall rock has the look of natural stacked stones.  It can be used in bird baths with at least 1.5 inches of water; the water flows from the top over the multiple layers.  It features a hidden water pump for a natural look and is made of a resin material to withstand outdoor weather elements.  The moving water is sure to help attract birds to your backyard.  This waterfall rock has tubing to attach to your outside water hose, no electricity needed.
