Flint Lockwood: The machine emits microwave radiation to mutate the water molecules. The more we ask it to make, the more clouds it takes in, the more radiation it emits, the more the food molecules could overmutate. I think that's what's making the food bigger.

Here's what I heard: "Science, science, science, bigger." And bigger is better. Everyone's gonna love these new portion sizes. I know I do. My dad thinks I should turn it off. Geniuses like us are never understood by their fathers, Flint. But what if things go- Who needs the approval of one family member... ...when you can have it from millions of acquaintances? Not to mention that little cutlet, Sam Sparks. And me. I've always felt that you were like a son to me, Flint. And I'm gonna be so proud of you tomorrow when you cut that ribbon... ...save the town... ...and prove to everybody what a great inventor you are. So here's the cheese: You can keep it going... ...get everything you've ever wanted...
