M-80 

An explosive firework. Was sold in the United States until the Child Protection Act banned them in 1966 because of the large amount of injuries due to mishandling or stupidity. An M-80 is usually about 1-1/2" x 9/16" with the inside of the tube filled with flash powder. One M-80 can easily remove fingers or send particles into the eyes causing permanent blindness.

"Dude, did you see that M-80 go off? It blew apart that entire mailbox!"

"I know I don't have a hand anymore, I lit an M-80 in my hand and it just blew it clean off. I would give you the finger but I have none left."

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. But the Child Protection Act of 1966 made M-80s and cherry bombs illegal to manufacture in the United State

I blew my finger off playing with an M-80.

M-80 

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.

Real M-80s were so strong that the military used them to simulate grenade explosions.
