Pop, pop, fizz, fizz, oh what a mess it is! .... Never, ever put "Emergen-C" vitamin powder into a bottle full of "vitamin water"! Not that you or I ever would, but Sara F did & oh, the mess on my floor -- like a wet, sugary volcano had errupted all over my floor. which I guess it did. Anyway, I had a good laugh at her expense. She didn't care, she was laughing too.
