Gun powder or black powder is one of the most significant creations in all of history, It is the biggest creation that shaped the war. People don't realize how dangerous gun powder is because it can propel an object a very long distance, which kills. The formula of gunpowder is 15% charcoal, 75% potassium nitrate, and 10% sulfur. Without gunpowder we would have no guns and be hundreds of years behind in the human evolution. Gunpowder has been used for hundreds of years and like all creations it will come out of date in a unknown amount of time when a better creation comes along and is more dangerous.
