The Dynamics of Soft Drinks
Ever noticed how soft drinks react to different foods that you eat? Specifically, the fizziness of the drink. There are some foods that I believe a good Coke enhances and brings out the flavor of, but there are also some foods that react quite violently to carbonated beverages.
For instance: Chocolate + Coke = lots of fizz. This occurs more often with Pepsi, but the effect is present with Coke as well. I have also noticed that anything salty reacts quite violently with Coke. For example, try eating a pickle, sweet or dill, and then chugging a can of coke. The sodium content in pickles causes the coke to literally explode in your mouth. But this fizz effect is limited mainly to the Coke/Pepsi family, and Sprite. Dr. Pepper, Mountain Dew, and other less carbonated drinks tend to be less volitile in the presence of sodium.
Proof of the fizz effect here!

Correction by Ben: It’s sugar not sodium that causes coke to explode. Nice. Should have deduced that from the mentos vid.
