It isn't this video itself that is actually the good watch. It isn't bad, but it doesn't really go in to detail. Rather, it brings up questions and at the end links to a bunch of good videos and channels I've been checking out. I don't have much beyond a high school level of scientific education, but I find the concepts very interesting. I found this video while watching the #1 question on the video. That video and the video for the #2 question are pretty interesting. I haven't had time to look at the others yet.
Anyways, I've clearly vaped too much while watching these vids, but TLDR is this is more of a resource video than the cool watch itself. Check the links during or at the end for what interests you.
