There's a difference between "not fully understanding the functioning principles" of something and "not understanding what is potentially lethal about the functioning principles" of something. I messed around with plenty of things I barely understood as a kid but I knew where to draw the line when it came to messing around with things I didn't fully understand. I knew to hold off and do my research (basically, ask a competent adult) before messing around with anything to do with flammable and/or "powerful" chemicals (think heavy duty, old school brake dust cleaner from my grandfathers garage), electricity (this saved me from electrocuting myself with the capacitors in a CRT TV), and high temperatures. There are certain things that will make sense to someone with a pretty extensive knowledge of the subject at hand but are still in the category where the factors at play should make one pause and consult a professional. One example would be people who hook up generators to their 220V dryer connection in order to power their house in an emergency (it's called backfeeding). Technically, that should work but if you don't think to throw the main you'll wind up injuring or killing the lineman expecting a deenergized line when they come to restore power to your neighborhood.
