Okay I confess to being a major nerd. I enjoy all those things which most people cringe over and proudly declare that I enjoy activities most are convinced that I should grow out of...someday. Anyway, point is, a lot of the references in Physical Chemistry are from my own stock of personal experiences. The below video just tickled me pink. I find the greatest things on Youtube. :P
P.s. It should actually be a D20 but it doesn't rhyme as well. See, told you I was an epic nerd.
