Circle of life demonstrated. The zero waste cycle.
David Latimer watered this spiderworts plant once 40 years ago and sealed the bottle. The plant has grown and thrived. The water gets taken by the roots and then transpired at night where it condenses on the bottle top and falls back down. The dead leaves and sunlight provide the food and drive photosynthesis.
