The newspaper also reported that during further exploration of his property he found his compass jittering. He built a "crazy house" and opened the site to the public in June 1941. Tour guides lead visitors through the attraction and perform various demonstrations to showcase the site's unusual effects. Prather died in January 1946; his son Bruce inherited the land and continued running the Mystery Spot with his father's business partner Vaden McCray. The McCray family was photographed for the ''

The Mystery Spot is a

, tilt-induced

visual illusion Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; thei ...

. The illusion experienced by visitors results from the oddly tilted environment as well as standing on a tilted floor. Inside the tilted room of the Mystery Spot, misperceptions of the height and orientation of objects occur. Even when people are standing outside on a level ground, the slant of the building in the background causes misperceptions as humans judge the height of people using the slant of the roof rather than the true horizon. These visual illusions include balls rolling uphill and people leaning farther than normally possible without falling down. Psychologists at Berkeley state that all of the misperceptions stem from the simple fact that the house is slanted at a 20 degree angle. Professor William Prinzmetal states, "When the perceiver's body also is tilted, the distorting impact on vision is greatly magnified—up to two or three times." Another point he makes is that distorted orientation causes other senses to fall back while one's visual senses become heightened. People standing at impossible angles and water flowing uphill are related to the angle at which the house sits. Other suggestions have been proposed to explain the reason behind The Mystery Spot's odd gravitational rules and illusions. Tour guides suggest that "a
