Does Blowing on a cup of tea make it cooler?

Blowing on a cup of tea will not make it cooler. In fact, it may actually make it warmer. When you blow on the tea, you are introducing warm, moist air into the cup. This air can cause the tea to evaporate, which will increase its temperature. Additionally, the act of blowing on the tea can create a breeze, which can also help to cool the tea down. However, the breeze is not strong enough to overcome the heat of the warm, moist air, so the tea will still remain warm.
