Teachers are notorious for saving every box, container, or random thing that might prove useful for a lesson someday in the far future. I admit that I am especially guilty of this as I teach a lot of hands on science that requires ... stuff. My classroom drawers are filled with things like Q-Tips, popcorn, and even chopsticks - don't judge. Someday those chopsticks will be just what I need.
Now and then, one of my colleagues will take an honest look at what is in her maybe someday cupboard. She will realize that someday is really never. The worthless items will then get deposited in the teachers' lounge for some other "resourceful" teacher to carry back to her own classroom. With a frequency that I am loathe to admit, I am more than occasionally that crazy somebody.
