My teenage son had the great idea to stack two wet tall-glasses in the sink; resulting in said glasses being stuck together solid.

Being a ninja, I quickly used teh Google to get me out of that jam. Lo and behold, physics was going to be my savior again.

I simply had to fill up a bowl with hot water, fill the inner glass with cold water, and put both glasses in the hot water. The outer glass expanded and the inner glass contracted enough for me to separate them within seconds.

Tada! Good too, because I like those tall-glasses. 🙂
