- stinos 2y agoAlso related, the rather counterintuitive theory / myth that hot water freezes faster than cold water. It comes up every winter here when it starts freezing and people want to leave out water for the birds. I can't help to urge people to just try it instead of simply believing it. I.e., it's not that I don't believe it's impossible under certain specific circumstances, but having tried it myself a number of times and the result always being that the cold water freezes first, it's pretty clear to me that it's a bit silly to just dismiss using warm water.
