You know, I actually got a potential idea for the use of potions while watching TV (on the WB), one day--it definately is an interesting possibility! Okay, okay, so it was while watching Felicity (now, don't look at me that way--it's not like *I'M* the one who convinced her to cut her hair!). Anyway, her roommate (if I recall correctly) was a Witch (albeit a rather messed uo "Witch" that didn't have her crap together) was hexing Felicity's ex. by brewing a potion and then throwing a pinch of his hair into the brew to manifest her desired goal (to get him toi trip and fall). Anyway, it *does* have interesting applications with re: the Sympathetic Magick, amongst others, I'm sure.
