This was based on an old Make Magazine article (this was back when said rag was actually really good.) The idea was originally that you would seal the jar, creating a self-sufficient chamber worthy of flying through space, or something. You put in what plants you have or can find, some shrimp, some pond scum (which is supposed to have critters in it,) and some other stuff.
I put everything in in January, so the pond scum didn't seem very viable at first. Nevertheless, after a few months, lots of strange swimmers actually started to appear. It only took me a week to chicken out and take the lid off of the jar, so I'll never know if my biosphere would have worked out, but some of the shrimp actually survived for about 7 months without any further input of anything. Now, in August, the jar is a bit of a wasteland...
