When you Microwave it, folow this suggestion. With Top on, and vent open, Microwave for 2 minutes. Swoosh the cup around to swirl the contents. (Easy does it cowboy!) Now put it back in for 1 minutes. When done, taske top off slowly. Should be warm enough that you don't have to fight the top. Easy, right? If not, go back to Home Education Class in HS.
