The skies over Steamboat Springs, Colorado, erupted in red as the world's largest firework launched Saturday night at the city's annual winter carnival. The firework shell weighed almost 2,800 pounds, about the weight of a Toyota Corolla, and was 62 inches -- a little more than five feet -- in diameter. A team at Steamboat Fireworks launched the shell from a 26-foot steel tube buried in Emerald Mountain, which overlooks the festival. Explosives propelled the shell out of the tube at 300 mph, and it rose nearly a mile in the air before exploding. The former world record for the largest firework was set in the United Arab Emirates in 2018 with a 2,397-pound shell.
