It's impossible not to delight in the vibrant splendor of this set of 3 Hummingbird, Butterfly, and Bell kinetic wind spinners. The eye-catching garden stake designs are brought into motion whenever the wind blows, and the attached bells jingle cheerfully in the breeze. The colorful pieces are made of powder-coated metal with weather- and rust-resistant finishes to prevent fading. Light assembly is required. Once the stakes are put together, installing your kinetics is easiest in moist soil or grass. If your soil is dry, pour 1 gallon of water onto the area and allow the liquid to soak in. Push the bottom prongs into the soil until they are completely covered. No tools are necessary. Wind direction varies on high and low pressure, so there is no optimal direction to place the kinetics.
