DAY FIVE: I was out of town for two days and when I returned, my amended column had lost a little of its water. There were trapped gas pockets in the mud so the mud level had risen and forced a little water to go up and over the edge of the bottle! The plastic wrap was also bulging a bit with trapped gas caught inside the bottle. So I undid both columns and took a bit of water off the top and also released some of the gas trapped in the mud of the amended column. It's interesting that the columns already looks so different. The control column without any oatmeal has hardly changed: the water is clear and I haven't observed any changes in the mud. The amended column with the oatmeal, however, has cloudy water, a lot of gas in the mud, it bubbles occasionally, and the sulfur smell was much stronger than with the other column. I never expected to see changes and differences so soon!
