Better living through chemistry.

It would be more physics than chemistry. So far as I know, the explosion has nothing to do with chemical reaction and is related to carbon dioxide and surface area in ways I may have understood in 11th grade but surely don't any longer.

SciAm had a blurb on their web site about this. Soda Fountains, or Diet Coke, Mentos and Surface Tension (http://blog.sciam.com/index.php?title=soda_fountains_or_diet_coke_mentos _and_s&more=1&c=1&tb=1&pb=1)

I just tried this with another surfactant (granulated dish detergent) and got similar, although less spectacular, results. I'm guessing that part of the reason that it wasn't as violent a reaction is that the granules seemed to dissolve slower.
