Im in the army and i have a few friends that are in iraq at the moment. They claim that to keep there bottled water cold during missions in extreme hot weather, they first soak a tube sock in cold water without wringing it out they slip the sock over the bottle of water keeping your water cold throughout the day? Does anyone know of this to be true? If so i would love to find out.
