          1. That seems more like concentrating sulfuric acid than making it. One of my BFFs from high school, back when he was about 10, bought flowers of sulfur from the local pharmacy, burned it over a platinum catalyst at low temp to make SO3, then bubbled that into water to make H2SO4. Now that's making sulfuric acid at home. He also got a visit from a detective from the town police, after the pharmacist thought about it. The detective, after seeing my friend's setup and talking with his dad (dad said "what's the problem? He knows what he's doing and is following proper safety precautions") said "Sir, in the future, we'd prefer it if you purchased materials for your son rather than him buying them directly"

    1. Gee, the bottom structure- you hydrolyze the two methoxys on the left to hydroxyls, and reduce the methoxy on the bottom to H, and you'd have dopamine.

    They'd still be classified if they weren't leaked through Hillary's emails!

    1. I happened upon an old Exxon street map of Baltimore that has been passed down from glove box to glove box, complete with a cartoon tiger on it. The toll for the Harbor Tunnel is listed as less than $1, and did you know they're working on building a bridge over the Patapsco to the south?

      ADC doesn't even publish latitude and longitude in their street atlases any more. Their latest grids aren't even necessarily lined up to true north! Luckily I stumbled across a 30-year old edition of my area of interest.

      The county GIS guy was depressingly happy to hear that someone, anyone was actually using his products.
