I was talking to a friend and he said on his winter trips, he boils his drinking water before he heads out for the day and hikes in freezing weather. He said it keeps his water from freezing as fast.
In high school I was taught that hot water freezes faster than cold water. I use an insulated sleeve for my water bottles in the winter, this helps a lot.
I told my friend what I thought, and he said there's no way that's true and his water doesn't freeze fast at all.
Any thoughts or experiences you can suggest or enlighten me with? I want to clear this argument up for good, and neither one of us are going to accept each others ideas. What do the members of summit post have to say on this topic?
