This is Scientific Americans' 60-second science.

The early years of the development of gunpowder, it was known as the devil's distillate because of its seemingly sinister properties.

So where do those properties come from?

Well, they come from the three principal ingredients of gunpowder, which are sulfur, charcoal, and salt

peter, three naturally occurring materials, which, when combined, produce something much

greater than the sum of their parts.

He served 34 years in the U.S. Army Corps of Engineers and retired as a Brigadier General.

He spoke at sea aboard a

scientific American cruise August 17th off the coast of Scotland. His subject was how fortifications

had to evolve once gunpowder was widely in use. Wrestler revealed a little basic chemistry

about the constituents of gunpowder and how they're represented in a familiar

uniform. Sulfur of mineral found in nature, yellowish or golden color burns at a relatively

low temperature, and that made it a material of intense interest in the Middle Ages where

alchemists were constantly looking for magical properties
