Usage

What is TNT? TNT is a yellow, odorless powder at room temperature. TNT is highly explosive and has been used in the making of military weapons and industrial explosives. TNT is often confused and used interchangeably with another explosive: dynamite. While TNT and dynamite are both explosive, they have little else in common. They have totally different chemical properties and are made from completely different ingredients. Because it is highly explosive and highly dangerous, TNT is almost always regulated by government agencies, such as the United States’s Environmental Protection Agency and the Federal Bureau of Alcohol, Tobacco, and Firearms. In the United States TNT can legally be made only by the U. S. military but can be legally purchased from other countries for approved industrial reasons. Using TNT in explosives is frequently depicted in popular culture, such as the Looney Tunes and Mickey Mouse cartoons. Example: Wile E. Coyote is often blown up by his own TNT when he fails to catch the Road Runner.
