As an avid moviegoer, I'm ashamed I didn't think of this earlier...

One of the best parts of the movie theater experience is the popcorn.  There's just something about it that can't be duplicated at home.  But when you're in the theater with the whole family, passing around the popcorn bucket can turn into a hassle.  And if one of the kids drops it, game over!

So try this instead.  Personally, I'll probably use a courtesy cup instead of a napkin; but still, this is a great idea!
