M-80 (explosive)

M-80s are a class of large firecrackers, sometimes called salutes. The Simulator, Artillery, M80, was originally made in the early 20th century by the U.S. military to simulate explosives or artillery fire; Later, M-80s were manufactured as fireworks. Traditionally, M-80s were made from a small cardboard tube, often red, approximately 1+1⁄2 inches (3.8 cm) long and 9⁄16 inches (1.4 cm) inside diameter, with a fuse or wick coming out of the side; this type fuse is commonly known as cannon fuse or Visco fuse, after a company responsible for standardizing the product. The tubes often hold approximately 2½–3 grams of pyrotechnic flash powder; one source states that an M-80 has at least 3 grams of powder. Some contain up to 5 grams or more.
