Does blowing on our hot food before we put it into our mouths actually make a difference to how hot it is?

I'm thinking that no, it doesn't. Which begs the question of why we do it? Is it a psychological thing?
You're viewing a single thread.
Yes, it does. By blowing over it, you evaporate some of its water, which cools it down. See also https://en.wikipedia.org/wiki/Enthalpy_of_vaporization
Thank you.
I think I saw a show 20 or so years ago that tried to debunk this and obviously either they messed up, or I wasn't paying attention.
(The show was called Brainiac).
You've been unclear on a fundamental concept of basic physics for ~20 years? Because a TV show said so? 😶
I mean it was called Brainiac and it did have John Tickle walking on top of a pool of custard. Are you suggesting I was wrong to use that as my foundation for all knowledge??
Nothing to see here. Carry on, citizen. we're so fucked as a species
