Witch's Balls have been very popular since the 18th century. First in England, then in New England, but their actual origin is considered to be much older. For well over 3 centuries hollow glass spheres have been hung in windows to ward off witch's spells, evil spirits and ill fortune. Hanging these decorative glass balls in the window or on the porch is thought to tantalize mischievous spirits which may be threatening a home's tranquility. The wayward spirit is mesmerized by the ball's reflective beauty. When the spirit touches the sphere it is absorbed and trapped in the web-like strands of the glass inside the ball, deemed forever harmless.
