Too much fizzy drink will rot your teeth, but if you are a small rodent, and if the drink happens to be called Mountain Dew, then it's actually capable of dissolving your entire body.This doesn't pass the sniff-test for me. Assume, for the moment, that a mouse fell into the can. the can goes down the production line, the soda is poured into the can and the top is crimped onto the can. A mouse weighs about an ounce or so. Since mice can swim, assume that they have a positive buoyancy, so let's go with they have a full-volume displacement of 1.3oz. In a 12 ounce can of soda, that means that 10.7 ounces will be Mountain Dew, the rest being our unfortunate mouse.
So claims PepsiCo, the global drinks behemoth which has cited the extraordinarily-corrosive nature of its bright green, citrus-flavoured product in an effort to defend itself against a personal injury lawsuit.
Is 10.7 ounces of Mountain Dew enough to dissolve a mouse? I have my doubts, but I'm not undertaking a research study.
Either way, ingesting a liquid that can dissolve small mammals does not seem to be terribly wise. If what you want is a achingly sweetened cold drink with caffeine, might I suggest that you switch to iced coffee or tea? You can make moth at home for a lot less money than buying cans of Pepsi Mouse Dissolver.
