Iron sulphate

After sunset, with the beginning of night, we start the process of rising again. Once more Iron sulphate is allowed to rise through the experiment formed during day, after several hours of interruption. The solution passes through the filter paper, reaches the border line formed during the day, passes it and rises higher until the second limit is reached in the early morning hours. Once more the filter paper dries. The second part of the experiment is finished.
