As some of you might know, I'm currently deployed to Kyrgyzstan. We've had no hot water for a few days now. Showering isn't bad but shaving sucks! I'm talking ice cold water! The hot water should be back by the end of the week. Any tips?
Best one I can think of at the moment is if you have (I dunno if they still have them actually) a MRE heater and a metal cup you could use those to make a military issue scuttle that would at least give you warm lather. Camp stove would also be a good choice if you have one.
Won't be as nice as a near unlimited supply of hot water, but better than a cold shave.
How about one of those camping showers that warms up in the sun? Or leaving a steel bowl filled with water out in the sun. Or soaking a black washcloth and leaving it out in the sun in a metal bowl Or some variation thereof...
