Some of this research has been done before. One of my more memorable experiences was having had the opportunity to smell the chemical that is added to gas pipelines… It’s added in unbelieviably small quantities and has a persistant annoying quaility that is difficult to ignore. If the dosage was upped, I’m pretty sure that it would repell all but the most hardened anti-globalization freak.

Also buteric acid… you know… vomit. Had a prof in hs that would dose a filter pad with it and then drop it in the locker of the kid he hated the most… on monday, he’d come in early and remove the filter pad (teachers have the locker combos)… meanwhile everything in the kid’s locker smells like a frat house after homecomming without the incriminating mess.
