talking food

imagine a snack that comes in a package with like 10 cookie like items, you grab the first one and crunch down on it but instead of a steady "crunch" the microscipic layers, designed at different thicknesses to break in a pattern, actually mimic a voice and say one short word, like "will" and as you eat each piece another word vibrates your teeth, this way you could have a sentence in a package, like "will you marry me" or "con grat you lay shuns" etc.
