I usually pee in the toilet a little. I can usually keep the Qf around 98 degrees for up to 3 hours just storing it in my shorts.
If it gets to hot blow on it a little once you rour it in the cup. There will be a temp strip on the cup. If its a little low rub your thumb against your clothes for a few seconds and then hold your thumb against the temp strip. Walk out of the room when it says 98 degrees
