This always confuses me. If I paint a spot it vanishes in no time, yet I have a kilgram of both Iodine and KI, so it's not like I don't have access to it. Also I notice that if I put some Iodine on a flat surface like a desk it stains it immediately, then I remove the source and it does something not unlike 'evaporates', so I'm not sure this method of testing means anything. I'm not sure evaporate is the correct term, perhaps its behaving more like a gas, I haven't researched that yet.
