I might have to look into these. I went looking for an Erlenmeyer flask a couple months ago and found out you can't buy one in the state of Texas. Apparently people use them to make meth so you can't buy one without applying for a permit. I looked into getting a permit out of curiousity and you basically have to sign a waver that gives a narcotics agent access to search your home and interrogate you. I decided it wasn't worth it and found a glass jug to use instead. Who knows what kind of "contraband" a narcotics agent might find while going through my homebrew equipment.
"Say, what is this thing you call a "hygrometer" and what do you use it for? And please explain this copper coil that suspiciously looks like something off a moonshine rig I saw on the Dukes of Hazzard."
