t-shirt

[luciab]

For the last two weeks I've been reading about the production of paper, parchment and vellum, complete with chemical descriptions. Every time I read this I want a t-shirt that says "Free the Radicals!" Sort of a flashback reaction, I guess. And yes, I know the more appropriate t-shirt would be this one but I obviously can't control my free association. Maybe I need a t-shirt that says "Free the Associations!"
