I stumbled across videos at www.youtube.com that showed what happens when you combine Mentos (the mint kind) and a soft drink. Most of the videos used Diet Coke. Perhaps everyone knows not to eat those two in combination but I never heard of it or gave it a thought.
Now I did have an episode during my high school years. We were given brand new uniforms that the band boosters spent several years in fund raisers to get for our little foothill school. We were performing a Christmas concert in our high school gym and during intermission I ate a Three Muskateers bar and then drank some cola. It was like Old Faithful. I tried to hold back the increasing pressure. My cheeks bulged out, my eyes widened, yes, I ruined the brand new uniform. It has a similar reaction to mixing baking soda and vinegar. But what happens if you swallow the Coke first and then eat Mentos. Could the massive expansion in your stomach kill you?
