CLEVELAND -- Do two stuck glasses have you in a jam?

Whether they're Pyrex containers, beer glasses or measuring cups, sometimes stacked glassware won't separate, no matter how hard you pull. You also risk breaking the glass if you try to muscle them apart.

Forget using non-stick cooking spray, or WD-40. The safest, most effective method uses a little science to get the job done.

Fill the top glass or container with ice. Fill a bowl with warm water, and place the two stuck glasses in the water.

As the bottom glass expands from the heat, the top glass contracts from the cold. The difference in temperature is just enough to weaken the seal, allowing you to pull the glasses apart.
