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

I'm thinking that no, it doesn't. Which begs the question of why we do it? Is it a psychological thing?

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).
