Corrected entry: Since the food falls directly out of the machine, and not from clouds in the sky, the food should only be falling in one general area at any given time, which makes the worldwide food storm in the end an impossibility. That being said, the purple food-shaped clouds throughout the film are unexplainable and pointless.

Correction: It's a fictional device which operates as depicted. It is depicted causing food to rain down all over town, and eventually all over the world, so that's what it does. There is no mistake here simply because the details go unexplained.
