1) if i have a friend pee the night before, would the testers be able to tell? i heard that pee holds its integrity for about 18 hours, but i'm not sure. is this true?
2) does anybody have any advice to keep the pee warm for 1-2 hours? i tried using body heat via ballsack/gouche but i was a couple degrees shy of normal temperature on every trial that i did. i can't seem to find hand warmers ANYWHERE cuz its summer... and apparently battery powered heating pads dont exist. IDEAS?!1
any help would be appreciated, thank you
