Have you watched the movie? Sangat entertaining okay.
Oh, by the way it’s a story of science and invention where water is used to produce food. From the poster you can see meatballs falling from the sky, no? That’s because the machine was thrown up to the sky (sounds illogical but nevermind, heh) and the water in the clouds were turned into food by the machine.
So instead of having H2O rain, the people are having food rain (or food shower, or whatever you can call it).
