Contrary to urban legend, an M-80 that contains 3,000 mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin -based high explosive, whereas M-80s or any other kind of firecracker contain a low explosive powder, like flash powder or black powder.

Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement.

In 1975, U.S. federal regulations were passed to limit all consumer-grade fireworks in the United States to a maximum of 50 milligrams flash powder, down from a previous maximum of 200 milligrams (though firecrackers mounted onto a rocket stick, or other aerial firework devices, such as Rockets, Roman Candles, and Cakes, may have up to 130 mg).

2022年2月27日 · Testing flash powders (for homemade firecrackers) from the most known ingredients at home. Sulfur, Sb2S3 as catalyst increased performance highly in all cases. In the case of sulfur, 10% catalyst was ideal. KClO4 Al 70/30 and KClO4 Mg/Al 50:50 they operated with significantly worse efficiency wit...

Traditionally, M-80s were made from a small red cardboard tube approximately 1.5 inches long and 9/16 inches in diameter, with a visco fuse coming out of the side. They contained approximately 2.5-3 grams of flash powder compositon. Today, M-80's whether professional grade or homemade are illegal to possess, use, or make.

2025年3月28日 · Flash powder is a rapidly-burning mixture of an oxidizer and a fuel—commonly potassium perchlorate and aluminum powder—and is guaranteed to light things up.

This document provides instructions for making dangerous explosive devices known as M-80s and M-100s using flash powder, along with formulas for different types of flash powder. It lists ingredients like potassium perchlorate, aluminum powder, barium peroxide and others that can be combined to produce explosions of varying intensity.

To comply with BATF and Consumer Product Safety Commission (CPSC) regulations, first-time customers of ours who want to buy flash-grade aluminum are refused automatically. Typically, this means M80's, cherry bombs, silver salutes, firecrackers, aerial salutes, rocket headings, and other flash-powder based items.

Real military spec. M-80s contained 3 grams of a mixture of aluminum flake, antimony trisulfide, potassium perchlorate flash powder in a 1/2"ID 2" long tube. There is a more exact mil-spec. John Conkling published what he claimed was the exact M-80 formula.

M80’s – The original M80 was a military simulator that was sold as a firecracker. It contained two grams of flash powder and was responsible for hundreds of serious injuries due to its powerful blast. These items were banned by the CPSC in 1966, and made illegal by ATF in the 1970’s.
