strip charges constructive as well as destructive

A class A bomb, take apart on scene. 1). Always prepare for the anti-handling devices.  One that I came across was a box full of explosive that was prone to inch its way down the road by itself instead of staying still???. Carefully taking it apart the timer was a starving rat. the circuit was a spring held apart by a piece of cord dipped in beef fat. Device. 4 holes in the base, rats feet thro. held by rubber bands. Rat eats cord, spring closes and Bang. Fault: the bomb builder didnt measure components, the cord was too far from the rat or the rat was too short for the bomb, he couldnt reach it, carrot and the donkey....the rat would inch its way forwards trying to eat the beef fat and the device would move down the road. Close thing as the device could vaporise people.
