Yeah, ok, but blowing on something colder than you will warm it up.
I mean, you can see the ice crystals melt on ice cream if you blow on it. This will work. Your breath is at body temperature. It doesn't just make things cold, you're not Superman.
- It works best with soup because soup, being somewhat liquid, distributes temperature better. But yeah, works for ice cream
  
  I think it works better for soup because soup is hotter to you than you are to ice cream.
  And, moreover, when you blow on something, the air that hits the thing youre blowing on is much closer to the ambient air temperature than your internal body temperature.
  
  I mean it works better for soup than for solid hot foods too. Still works for the latter, but takes a bit more to cool down the inside if it’s a thick piece.
  
  Also works for your own hands (though I generally do not recommend eating those)
  
  Maybe just the tips
  
  No no, I've played this game before. Fool me once shame on you, fool me, ya can't get fooled again.
  
  I feel like the moisture from your breath makes your hands colder overall.
  
  Also works for soup because of evaporative cooling.
- you're not Superman
  Speak for yourself!

- I'd think that the ambient temperature of the air is more important than the temperature of your breath. Though it doesn't change much, since it's also higher than the temperature of the ice cream (usually)
  
  If it’s not warmer ambient than ice cream, I think most people drink hot coffee or tea instead of eating ice cream.
