PEPCON Disaster - The Greatest Chemical Explosion in American History
The PEPCON disaster was an industrial disaster that occurred in Henderson, Nevada on May 4, 1988 at the Pacific Engineering Production Company of Nevada (PEPCON) plant. The chemical fire and subsequent explosions claimed two lives, injured 372 people, and caused an estimated US$100 million of damage. A large portion of the Las Vegas metropolitan area 10 miles (16 km) away was affected, and several agencies activated disaster plans.
Pepcon was one of the only two American producers of ammonium perchlorate, an oxidizer used in solid fuel rocket boosters, including the Space Shuttle and military weapons. The fire and explosions were caught on videotape by television engineer Dennis Todd, who was on Black Mountain performing maintenance on a television tower.

Bullet Ant
Paraponera is a genus of ant consisting of a single species, the so-called BULLET ANT, named on account of its powerful and potent sting, which is said to be as painful as being shot with a bullet. It is called by the locals "Hormiga Veinticuatro" or "24 (hour) ant", from the 24 hours of pain that follow a stinging. The bullet ant inhabits humid lowland rainforests from Nicaragua south to Paraguay. Workers are 18–25 mm long and resemble stout, reddish-black, wingless wasps.
The pain caused by this insect's sting is purported to be greater than that of any other Hymenopteran, and is ranked as the most painful according to the Schmidt Sting Pain Index. It is described as causing "waves of burning, throbbing, all-consuming pain that continues unabated for up to 24 hours". It is thought that the ant has evolved this way to ward off any predators who would normally unearth them. In some indigenous communities, to enter manhood, a boy has to endure being stung by the ant 20 times without screaming. A paralyzing neurotoxic peptide isolated from the venom is poneratoxin.
