Fahrenheit Freezing Point of Water
Next time you see a weather forecast with “32°F,” smirk. You know the secret. You know it could have been 0, or 50, or even 100.
It’s a fun party trick. “Hey, did you know water freezes at 32°F because Daniel Fahrenheit made up a scale using salt slush?” People will look at you like you’re a genius.
And you are. Because you understand that the freezing point of water is not a rule of nature. It’s a rule of thumb. A very, very specific, slightly arbitrary, thumb.
So go ahead. Stare at an ice cube. Whisper “thirty-two.” You’re in on the joke now. The water is just following orders from an old German glassblower. And that’s pretty cool.
