Seventy-two years ago today, on July 16th, 1945, the world’s first atomic bomb was tested in a remote stretch of desert in south-central New Mexico known as the Trinity Site. This test occurred only weeks before two of them were dropped on Japan in an effort to end World War II. The mushroom cloud it created was seen for miles, and created an enormous crater in the ground. Today, all that remains of the birth of the atomic age is that crater (eroded to be mostly flat), the McDonald family’s ranch house where the bomb was assembled, and some strange green glass that was created by the detonation. This glass is strewn all across the crater, and every piece is the property of the U.S. government. It is also slightly radioactive. (We put it back down on the ground after examining it!)
This glass, called Trinitite, is found nowhere else in the world.
