Strategic National Ontological Weapon (SNOW)
SNOW is a suitcase-sized product of early Cold War Weird Science, and it shows: everything about it is glass and dials and a steel casing that can absolutely shrug off a bullet. It was ‘invented’ in 1946 by the State Department’s Interim Research and Intelligence Service (IRIS). More accurately, it was invented in 1942 by a tame mad scientist seconded to the Office of Strategic Services’ Research and Analysis branch, who then got transferred over to State in 1945, along with the rest of what would become IRIS. Once that happened, the State Department felt comfortable officially telling Harry S Truman that he happened to have a single-use cosmic reset button.
