United States (Steamboat Springs)

The largest aerial firework shell weighs 1,268 kg (2,797 lbs), and was achieved by James Cowden Widmann, Eric Krug, Ed MacArthur, and Tim Borden (all USA) in Steamboat Springs, Colorado, USA, on 8 February 2020.

The final shell measures 1.44 m (4 ft 8.75 in) in diameter, made of over 82.07 km (51 mi) of 5.71 cm (2.25 in) gummed paper tape, wrapped in even layers by a machine built especially for this purpose. The completed shell is at least 17.78 cm (7 in) thick, and was filled with 380 individual comet fireworks. A giant mortar, 1.57 m (5 ft 2 in) in diameter and 7.92 m (26 ft) deep, had to be specially built to shoot off the giant firework. The record-breaking shell closed the firework display for Steamboat Spring’s 2020 Winter Carnival, an event that has occurred annually for more than 100 years.
