The hard part was obviously not measuring temperature. It's communicating people how to visualize/think of something that gives the feeling. Because the feeling is subjective and even I as the person experienced it have hard time explaining it. It's much harder to explain it to others and make sure they did correctly. I don't need results anyway, I _know_ it works so there isn't a chance that "I won't like" the results. I just want more people to benefit and an incorrect experiment may block them, not me, from proceeding further.
