CNN reports on new methods of tracking terrorists using unique explosive “fingerprints”.
The blast chamber looks like a giant meteor. Weighing 20 tons, it is made of 9-inch-thick slate gray steel.
It sits on rubber shock mounts which cushion the force of blasts that expand the walls of the massive sphere.
High explosives used to ignite nuclear weapons have been tested here. The device scientists are preparing to test today is simpler. It’s made of a half-pound of high explosives and looks like a thin red pencil, wired to sensors that will record the shape and energy of the blast.
