It looks like my anaerobic composter is working. You can see in the picture that the trash can has risen quite a bit. The water lines on the side show just how much it's gone up. When it started out, the top of the barrel was level with the water. Now I need to figure out what to do with it.
Oh, I recently read that hydrogen sulphide (the component of biogas that makes it stinky) is toxic! Go figure. I guess I must've slept through chemistry class the day they went over that.
