Diet Coke and Mentos

Apparently, videos like this one are some thing of an Internet phenomenon (nod to JD for this one). Someone discovered that Diet Coke and Mentos (also known as "the freshmaker") react violently when mixed together.

I'm a bit cynical. I think the Diet Coke marketing team figured this out and started rumors so as to sell their vile product and get more exposure for it. Why the Diet Coke people and not the Mentos people? Because why single out Diet Coke of all beverages? Why no hubub about Diet Pepsi or regular Coke. In any case, the clowns at that site are soon going to post the results of tests with other beverages and candies. Should be interesting.
