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

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

You can test your hypothesis of "no, it doesn't" pretty easily. Feel free to report back with results and method used.

Methods:

Make a cup of Hot Chocolate
Get two spoons, put them in your hot chocolate to warm up to remove the variable of heat transferring into the spoon.
Take one spoon out, fill it up, blow on it for a few seconds, then put it in your mouth.
Take the second one out, leave it out for the same amount of time you would have if you had blown on it, then put it in your mouth.

Report on temperature difference. If you had an instant-read thermometer you could even be more certain of the results.
