Detonation dissolved the bonds holding the centrifuges together so that 
each of a thousand or so ballisticules suddenly flew outward. The enclosing 
shell shattered easily, and each ballisticule kicked up a shock wave, doing 
surprisingly little damage at first, tracing narrow linear disturbances and 
occasionally taking a chip out of a bone. But soon they slowed to near the 
speed of sound, where shock wave piled on top of shock wave to produce
a sonic boom. Then all the damage happened at once. Depending on the initial 
speed of the centrifuge, this could happen at varying distances from the 
detonation point; most everything inside the radius was undamaged but 
everything near it was pulped; hence, "cookie-cutter." The victim then made a 
loud noise like the crack of a whip, as a few fragments exited his or her flesh 
and dropped through the sound barrier in air. Startled witnesses would turn 
just in time to see the victim flushing bright pink. Bloodred crescents would 
suddenly appear all over the body; these marked the geometric intersection of 
detonation surfaces with skin and were a boon to forensic types, who could 
thereby identify the type of cookie-cutter by comparing the marks against a 
handy pocket reference card. The victim was just a big leaky sack of 
undifferentiated gore at this point and, of course, never survived.
