I had a friend at work send this to me after I mentioned they don't make enough Max and Pretzel M&M's to medicate me this week. He suggested I tried mixing the two and see if my results were as good as Diet Coke and Mentos.
It would be fun, but I think it's a perfectly good waste of both of them with no internal benefit to me. But fun, just the same. Almost as good as the synchronized sprinklers at DisneyWorld!
