One of the most public and extensively seen demonstrations of these phenomena in history, a stunning ball lightning event took place at the Paris Opera House on July 5, 1846. A big, brilliant sphere supposedly dropped from the chandelier during a performance on a windy evening, sparking audience terror. Eyewitnesses said the ball gleamed with a strong blue-white light and resembled a human head. For several minutes, hundreds of people watched the sphere slowly float throughout the air, apparently against gravity. It allegedly divided into smaller spheres as it moved across the auditorium, then vanished with a thunderous explosion, leaving behind a strong osmell of ozone. The great number of educated witnesses—scientists and Parisian elite members among others—who gave thorough and consistent reports of the events makes this event especially remarkable. The Paris Opera House viewing was crucial in helping ball lightning to be accepted as a real atmospheric occurrence deserving of research. Researchers investigating the characteristics of ball lightning have found great value in the thorough observations given by the audience members—including descriptions of the color, movement, and behavior of the ball. This incident also spurred a public and scientific community alike's growing curiosity in ball lightning, which resulted in more reporting and documentation of related events. Challenging theories linking the phenomena to just outdoor electrical storms, the episode at the Paris Opera House remains one of the most intriguing and well-documented examples of ball lightning in an inside environment. It is still frequently quoted in scientific publications as a perfect illustration of the erratic character of ball lightning and its capacity to show up in unusual places.
