The Illuminarie Dragonfly Anemometer Stake is a piece of metal garden art that is attractive, eye-catching, and mesmerizing to view, making it a great conversation piece. It is an ideal focal point for any outdoor landscape setting, as the eye is naturally drawn to it - especially when it's in motion. The self-orienting spinners rotate effortlessly in the slightest of breezes. Durable, electroplated and powder-coated parts will make this garden accessory provide years of use and enjoyment. Luminescent crystals in the hand blown art glass gazing ball absorb the Sun's energy during the day and release a subtle green glow at night lasting up to 4 hours, gradually fading over that time. Measures: L 8" x W 8" x H 34"
