M-100 (explosive)

M-100's are a class of powerful firecrackers commonly called salutes.



Description
M-100's generally consist of a cardboard tube 2-1/8" x 3/4". Colors may vary. They contain 10 to 15 grams of flash powder that is ignited via a visco fuse positioned in the center or side of the tube.

In the United States, M-100s are illegal to manufacture, possess, and sell without a proper license, and are regulated by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). M-100s were first banned by the Child Protection Act of 1966.

Accidents
In 1983, an explosion at a secret unlicensed fireworks factory manufacturing M-80 and M-100 fireworks near Benton, Tennessee, killed eleven, injured one, and inflicted damage within a radius of several miles. The operation was by far the largest-known illegal fireworks operation in US history, and the initial blast was heard as far away as 20 mi from the site.
