ROSEY

Heat expands metal and my guess is that while the metal was expanding the moisture along with air was escaping in the form of steam and that you created a nice strong vacuum seal. Try putting the pan under the faucet in cold water and the metal will shrink back to it's normal size thus allowing the air pressure in the pan to normalize.

Okay, anyone out there who remembers high school physics better than I is free to correct me. I'm not too smart about such matter.
