If you've ever worried about the effect of Pop Rocks on soda, you should definitely check out what a Mentos can do to a 2 litre bottle of Diet Coke (like cause a 100 foot geyser). According to AdFreak, the two companies have had completely different reactions to the viral videos circulating. Mentos loves it, while Coke is not amused, and doesn't think it fits their Diet drinker profile. In any case, I'm just glad to see that kids have finally moved beyond experimenting with the traditional baking soda and vinegar explosions.
