Has anyone actually TRIED combining Mentos and Diet Coke before? I always want to, but I'm afraid to make a mess.
I DID, however, try the Pop Rocks and Coke thing. There's an urban legend that bad things happen if you try to drink Coke and eat Pop Rocks at the same time, but to be honest, all it did as push the Pop Rocks to the back of my throat. Bummer.
