‘Rope tricks’ are seen in this image of a nuclear explosion taken less than one millisecond after detonation. During operation Tumbler-Snapper in 1952, this nuclear test device was suspended 300 feet above the Nevada desert floor, and anchored by mooring cables. As the ball of plasma expanded, the radiating energy superheated and vaporized the cables just ahead of the fireball, resulting in the ‘spike’ effects. (Dept of Defense image via The Atlantic)
