From the Disney Parks Blog:
It’s very exciting around Disney’s California Adventure park these days. In this video we take you inside the control booth as Walt Disney Imagineers work overnight testing lights, fire and nearly 1,200 fountains for the new nighttime spectacular “World of Color.” You’ll also see some exclusive footage from our time lapse camera and more glimpses of the show. “World of Color” is set to debut on June 11. Enjoy!
