One of the key experiences at Disney World is the Wishes Nighttime Spectacular fireworks show over Cinderella’s Castle. This show plays every evening, 365 days a year, as does Epcot’s fireworks display, Illuminations. Not surprisingly, Disney is the largest consumer of fireworks in the United States, purchasing over 1 million fireworks each year. If you’re worried about the environmental impact of all of these fireworks, never fear! In 2004, Disney pioneered the use of compressed air, rather than gun powder, to launch fireworks. Disney Cruise Line even uses fireworks made from biodegradable materials, which become fish food when they fall into the ocean. The rumor is that they’re made from potatoes.
