Everything nowadays seems so complicated that we need to break it down into its simplest form in order to understand it. When I was in the jungle, I carried the explosives we used two destroy the cocaine labs. Trying to understand the scientific facts of how explosives work can be complicated. It wastes a lot of time looking at formulas, trying to figure out the best locations to place the dynamite.
We didn’t have a lot of time to do that. I learned in my training the simple fact is energy caused by the explosion always travels along the path of least resistance. If you wanted the explosion to travel in a certain direction, he just had to pile rocks and other heavy objects against the charge on the side opposite of the direction you wanted the explosion to travel. You don’t have to complicate things in order to obtain great results.
