This water fountain is made from a stainless-steel dish that catches and drains the water from the organic shape above. There is a small pond pump that sits in a five-gallon plastic waste basket below the dish in the rocks. The pump has a tube that recirculates the water back to the top where it falls again down over the copper leaves that mimic Hosta leaves creating drips and beads. Birds absolutely love and depend on this fountain. I have a small pond heater in the reservoir below so that they have a water source year-round. Hummingbirds actually sit right in the bubbler for baths.
