This question already has an answer here:
Lets say you have a nice bowl of piping hot soup. You use your spoon and take a sip and realize its too hot. So you blow on it a few times and now its cooled enough that it doesnt burn your mouth.
Obviously, blowing on the liquid will reduce the temperature, but is that really what is cooling it? Or perhaps the heat is moving to the metal spoon?
Is blowing on the liquid cooling the liquid more than the heat being transferred to the metal spoon holding the liquid?
