Welcome to brain Stuff from How Stuff Works, Hey, brain Stuff. Lorn Bogel bomb here. It was theoretical physicist J. Robert Oppenheimer who chose the code named Trinity for his trial run of atomic weapons, though he could never remember why. As a participant in the Manhattan Project, he oversaw the construction of four atomic bombs. By the spring of nineteen forty five, the U. S Military had started looking for
a place to test one of them. Out Sites in California, Colorado, and Texas were considered before the Pentagon chose a patch of terrain at the White Sands Missile Range in New Mexico is the site of the Trinity Project. On July sixteenth, ninety five, at five twenty nine a m Mountain time, a plutonium bomb known simply as the Gadget was detonated at the site. This marked the first deployment of an
atomic weapon in recorded history. Within a month, the United States used two atomic bombs to level both Hiroshima and Nagasaki in Japan, helping bring World War two to an end and sending a very clear and violent message to other world powers. So began the atomic Age. Back in New Mexico, scientists discovered that the explosion that had started at all left something behind. Nuclear physicist Herbert L. Anderson and his driver inspected the Trinity blast site shortly after
the bomb detonated. Over the radio, he announced that the area had turned all green. A layer of small, glassy beads covered the crater. Most were all of green in color, though some samples were black or reddish in hue. The substance is now known as trinotite. Plenty of trinotite was still there in September nineteen forty five, when a Time magazine report described the crater as a lake of green
jade shaped like a splashy star. Physicists realized that this trinotite was desert sand that had melted down during the blast and then resolidified. Our understanding of trinotite has changed recently. At first, scientists assumed that the grains of sand that turned into this material had melted at ground level, but a twenty ten study found that the sand was actually pulled up into the heart of the explosion, where high temperatures liquefied it. The stuff later rained down, cooled, and
turned solid. There are no laws against buying or selling trinotite samples that have already been collected, but it's now illegal to remove this substance from the blast field. You will find much of it on site anyway. America's Atomic Energy Commission bulldozed over the nuclear test site in nineteen fifty three. In the process, a bounty of trinotite was buried underground, and buyers beware, there's a lot of phony
trinotite on the market. Trinotite is indeed radioactive, however, it's been deemed basically safe by a health physics survey, so the glassy beads were snatched up in huge quantities by souvenir hungry visitors to the site. Jewelry created with trinotite was even made for the purpose of propaganda. These kinds of glassy residues are left behind whenever nuclear weapons go
off at the ground level. They've been recovered in the wake of atomic tests over such places as the Algerian Desert, but the name trinotite is typically reserved for specimens found at the original Trinity site at the White Sands Missile Range. Some scientists prefer to call material found in other parts of the world atom site Today's episode was written by
