Explosive device used by the residents of Alabama to remove their own hands.

A firework that contains about 3 grams of pyrotechnic powder. Most M-80s are actually pieces of crap that contain tiny amounts of powder compared to genuine M-80s (firecrackers are called M-##, where ## corresponds to the amount of powder it has in grams). Illegal since 1966.

people for whatever reason, consider m80's to be "fireworks" or "firecrackers". but dynomite is an explosive, and whats an m80? quarter stick of dynomite!!

they don't make big colorful sparks in the sky, nor small colorful sparks on the ground/partially in the air. no,the soul purpose is to literally blow something up with an m80. a solid object, not just blown of for the hell of it. make sense? stupid? idk. idc. it's just my point.

M-80s were invented by the military long ago to simulate grenade explosions during training missions. Soon they became extremely popular with the public, and were sold as large firecrackers. legal firecrackers may only have 50 miligrams in them, but M-80s have about 3 grams each, making them incredibly dangerous and capable of blowing up an entire hand.

A big ass illegal firecracker/quarter stick of dynamite.Used by the army as simulation grenades for training, but some ordinary people wanted them to play with so they stared selling them at stores, until people started blowing there hands off. Now there illegal.
