My kid did a science project once where he got a bunch of human teeth from our dentist and then soaked them in about 20 different liquids, including whiskey. And guess what fluid ate the teeth up as if it was blood from "The Aliens" space monster?
Good ole Coca-Cola. I aint kidding, the stuff is so toxic it should be shipped in special rail train containers. The ones with all the scary signs on them. Next time you guzzle one just imagine that crap seeping into your guts and eating them out. Your better off guzzling Jagerbombs.
Diet coke actually rots tooth enamel almost twice as fast as regular coke, and the artificial sweeteners they use are almost all known carcinogens (as soon as they come out with a new one, they find out its just as bad as its predecessor). I'll take a little extra acidity to black teeth and stomach cancer, thanks.
Plus, diet tastes like flat store brand cola with an old sock soaked in it for a few days.
