As the minutes tick toward midnight on Saturday and you are running out of conversation topics, why not bust out some trivia about the science of champagne to impress your friends.
The Discovery Channel says they may already know about French law, which decrees that grapes must be grown in the region of Champagne in order for sparkling wine to qualify as true champagne.

This law of physics states that the pressure of a gas above a solution is proportional to the concentration of the gas within the solution. For champagne, carbon dioxide is the gas that forms those delightful bubbles. And, in an unopened bottle of champagne, there is equilibrium between the CO2 inside the liquid and the gas in the spaces of the cork.
