Science Experiment: Mentos and What??

For my daughter's Science Birthday I was dying to do the famous Mentos and Diet Coke explosion experiment.  It is so cool looking.  But... it's not that pretty.  So for the Sparkly Science party, we decided we'd test out different kinds of sodas. We did the Diet Coke, but we also did Diet Cherry 7-Up, and diet orange soda.  It was awesome!  All the sodas worked just fine, and since we had a variety of drinks the kids could compare to see which went the highest!  I preferred the colored choices for sheer coolness factor, and they went plenty high!  Here are some pics
