zero-Celsius physics
When I was a child in Florida, I heard of people putting salt on the roads in places far to the north. I marveled at the idea. Yesterday afternoon, at the age of nearly fifty-six, I salted my front steps and walk for the very first time.
And then I observed the next morning, after a night well below freezing, that there was no ice in places that didn't get salted, nor was there liquid water. The places that I salted? Damp. Somebody forgot to tell the local weather gods that sublimation isn't supposed to happen on this planet or something.
