What is it????

My only guess for the mystery package that we saw in class is that it is a package of "junk e-mail." I think the whole purpose of this exercise to expand our brains into a new way of thinking. While I was examining the package my brain went through every possible option conceivably possible. At first I was thinking it was propaganda, or information to join a cult. However I am still drawing a blank on what it actually could be.
