This is a 5L bottle for wine. I found it on the dumpster. Taken home, cleaned, and thought about what I could do with it.
I wanted to have some life in the apartment. I recall a video about the ecosphere experiment posted on Reddit. That inspired me to follow the same path.
I get to the nearby lake. I took some mud, algae, water, and one plant. Then put it all back to the bottle ecosphere.
It was 5/31/2020 middle of the sunny day when the experiment has begun!
From time to time I will do a report about the life in ecosphere. I'm not a biotanist so I can only write what I saw.
