This finely balanced wind vane adds movement and elegance to any garden. Young and old alike will enjoy watching the wind push the aluminum cups around this two-toned Kinetic Wind Vane. Based on the design of a centrifugal regulator, as the wind increases, the hinged joints at the top allow the aluminum arms to rise. In doing so, the brass finials at the end of each arm will point to the relative wind speed, depicted in beautiful illustrations on the brass arm below. At the same time, the solid brass arm will gently turn to face the direction of the wind.
