Certified scuba divers play a hidden yet crucial role as safety divers in Cirque Du Soleil’s “O” performance at the Bellagio in Las Vegas. This show features acrobatic performances above a massive pool holding 1.5 million gallons of water. While the audience focuses on the stunning acts above water, a dedicated team of divers supports the production from below the surface, ensuring safety and smooth operation. Their work is essential to the show’s success, even though it often goes unnoticed.
