We went at about 5:30 pm and it was 28 degrees fahrenheit outside (AKA really cold).
I started to dig for mud, and I found a pencil. The mud was filthy and foul-smelling.
I set up my column the next day (Friday ) at about 10 am. Here is the set up:
The contents needed for the column setup are as follows, starting from left to right:
- 2-liter bottle with pond/lake source water (far left)
- Mud in a gallon Ziploc bag (top middle)
- Old pasta sauce container to act as the column container (bottom middle)
- Raw egg yolk (sulfur source) (top right)
- Shredder newspaper (carbon source and cellulose) (bottom right).
I mixed the mud with source water until the mud became soft and pudding-like in consistency. Then, I added the shredder newspaper and an egg yolk. Then, I added the contents into the old pasta sauce jar and made sure to shake the mud down into the jar to get rid of air bubbles. I topped off the mud in the jar with source water until it reached the brim. Here is a photo of the column prior to adding the cellophane wrapper on top, but after the source water was filled to the brim:
