The document discusses the design of a cart prop for a film set. The cart was designed to look worn and old to match the dirty and distressed set. Primary colors like red and blue were used to make the cart stand out against the brown and cream colors of the rest of the set, as it was a main prop. The size of the cart was scaled proportionally to the rest of the set to seem more realistic. The cart also served a functional purpose by holding "piraguas" or slushies to tie into the story.
