Hey guys, I'm looking for an anime movie possibly from the 80's that I saw quite a long time ago. All I remember is that it was set in the future and the main character which is a boy lives on a floating ship with I'm guessing is his elder brother and some other people. I also remember the boy kept eating throughout the movie and someone eating quick noodles in a cup with a string attached which you can pull to cook the noodles instantly (this the only part of the movie that I can really remember). The ending shows the destruction of a prominent city with an oldies playing in the background. I know the description I gave doesn't have any heads or tails but its all I've got. Any ideas??
