This is a video from the Faber-Castell pen manufacturing plant in Engelhartszell, Austria detailing how the “superfluorescent” Textliner 48 highlighter is made. The factory in Engelhartszell produces some 35-million pens and markers every year, and I suspect at least half of those eventually spend some time in a person’s butt. And if they made Sharpies I’d say 95%. Nothing wrong with that. My point is this: let’s fill some empty liquor bottles with water and the ink from highlighters and add a blacklight so they glow and we’ll have the coolest room in the whole dorm!
