Echo Valley 4353W Illuminarie Leaf Dual-Motion Windwheel, 15.75 by 5 by 45-Inch Kinetic wind petals will catch the wind on a gusty day and rotate via perpetual dual-motion; Each piece will rotate in opposite direction Kinetic garden stake is made of metal and art glass with an antique copper powder coat finish to withstand the elements and prevent premature rusting for years of use and enjoyment Product is stationary and must face the direction wind is coming from for movement to occur Center glass orb absorbs sunlight during the day and emits a soft, subtle green glow at night. Glow will only occur within the green swirl portion of the globe and is comparable to the glow seen on a watch face piece Note: For best results, place windwheel in a location where it will receive no competing light source at night. Glow will gradually fade over time.
