Twin airfoils for mounting to a push broom or brush used in the winter sport of curling. Main objective is to aerodynamically enhance brushing performance by utilizi ng a curved surface to create a Coanda effect (tendency of air to follow a curved surface), reducing air pressure on the leading surface of a moving curling stone. As a secondary benefit, these "wings" help reduce ice-contact friction of a brush used as a sliding balanc e during stone delivery. May also modernize or enhance the appearance of a curling brush, similar to how adding an air spoiler to an automobile aids defining a sports car.
