This Solar Watermill Fountain with Spinner is full of surprises! The watermill is powered electrically, which in turn twirls the helix spinner at top, while the lights in the left cottage are solar powered. It's a wonderful sight to hear and behold! Our self-contained Solar Watermill Fountain with Spinner comes with a quiet, submersible pump, allowing water to flow from the upstairs spout, down the watermill and into the basin. Made of weather-resistant resin, it's durable enough to be displayed outside in a garden or on your porch, but so much fun that you might want to showcase it inside.
