Have you ever been in the situation where you or someone you know must have a drink of something but no one has a cup? This has happened to me several times when I have desperately had to take a migraine pill. Frantic! There used to be accordion fold up cups but I don't know if they still exist.
Anyway, I found this tutorial to make a cup from a sheet of paper. It looks like something I learned in Girl Scouts, but that was so long ago ....etc.... etc. As you can see from the pic below the tutorial is a moving pictorial. This moving stuff could drive you crazy after a while but it is effective.
So click here for all the particulars. The tutorial is from www.Wikihow.com
Meanwhile .... keep it simple and have a great day.
