Crystal balls are imagined to provide a way to see into the future, though there is no evidence they actually have this power. In the movie The Wizard of Oz, crystal balls are used to view events elsewhere or what may happen. While a crystal ball cannot truly predict the future, some people still use the information they provide to make decisions. Additionally, crystal balls can make beautiful decorative objects for the home, coming in many sizes, shapes, and themes. Though they cannot show the future, they remain interesting conversation pieces and accessories.
