What does "be made out of" mean? Is it different from "be made of"?
You can use either "made out of" or made of to say that something has been created using a something, so that the original thing is completely changed. Ex: The new boat was made of bamboo. Ex: The dinner forks were made out of solid gold. There is a slight nuance in which if something has been produced from another thing in an unusual or surprising way, you usually use "made out of". Ex: Her hat was actually made out of plastic bags. Aside from this however the two phrases are essentially interchangeable and mean the same thing.
