A germane chemistry story but not about lubricants. I grew up in Atlanta. My mom was a scientific librarian and for a while she worked in the chemistry department at Coca-Cola. She worked with the guys who knew the syrup secret formula ("7x"). She told me she had to burn her carbons (this was before duplicating machines). She could take shorthand and perfectly type organic chemistry expressions using just a regular typewriter; truly lost skills, anymore.
