For more than 100 years, this 5,200 pound granite ball has slowly rotated on its pedestal. It’s movement in not detectable by the naked eye. How then, do we know it moves? When the monument was first set in 1896, the bottom of the sphere was not polished. Within two years, this unpolished spot was visible. The family had the stone reset, but again it rotated and the unpolished spot is visible. It moves approximately 2 inches a year.
Although there are many speculations, there is no definitive theory as to why the ball moves. It weighs too much for a person to move, and there are no scrapes on the ball indicating a group of people have moved it.
Some theorize there is an air or water pocket below the sphere, allowing it to move freely. Others believe the movement is the result of seismic activity, and still others think the ball is heated unevenly causing it to expand and contract unevenly as well. There are also those who believe the movement is due to paranormal activity.*
Many believe touching the ball will bring you luck.
What do you think? Is the movement the result of seismic activity, construction defect, or is it haunted?
