Rules of Nature

In a recent presentation about electrical safety, the students learned that electricity will always take the easiest route to the ground... even if that means traveling through a person's body. This information was troubling to one of my students. In the days following the presentation, he asked me several times why electricity would always find the easiest route to the ground. Lacking a better explanation, I said, well, I guess you could say it's a rule of nature. I could see this little boy was clearly not satisfied with that answer. When I asked him what was troubling him, he replied, "Well that 'rule of nature' has SERIOUSLY HURT a lot of people!!"
