A thriving sealed world since 1960
On Easter Sunday in 1960, David Latimer embarked on a unique experiment. He placed spiderwort cuttings into a ten-gallon carboy with compost and a quarter-pint of water, then sealed it with a greased cork. Positioned near a sunlit window, this enclosed ecosystem began its decades-long journey.
Sixty-six years and counting
In 1972, twelve years after initiating the terrarium experiment, Latimer opened it for the first and last time to water it. Since then, it has remained untouched. More than 66 years later, this thriving closed terrarium is celebrated as the world’s longest-living sealed ecosystem, verified by sources like “Tropical Glass” and “Wikipedia“.
How it flourishes
The terrarium continues to flourish without external interference. Latimer rotates it occasionally to ensure even exposure to light. He has expressed a desire for it to be preserved, either by passing it down to his descendants or donating it to the Royal Horticultural Society.

The self-sustaining marvel
This carboy functions independently, relying solely on light:
- The Water Cycle: Water is absorbed through the roots, released during transpiration, and then condenses on the glass, returning to the soil.
- The Carbon Cycle: Photosynthesis generates oxygen and sugars during the day. At night, respiration and decomposition processes consume oxygen, releasing carbon dioxide for ongoing growth.
Remarkably, it operates as a self-regulating biosphere where the ecosystem flourishes naturally.

Frequently asked questions
How long has David Latimer’s terrarium been sealed?
David Latimer’s terrarium has been sealed since Easter Sunday in 1960, making it over 66 years old.
When was the last time the terrarium was opened?
The terrarium was last opened in 1972, twelve years after its initial creation, to add water.
How does the sealed terrarium sustain itself?
The terrarium sustains itself through processes like the water cycle, where water is absorbed and then condenses back into the soil, and the carbon cycle, where photosynthesis and respiration maintain the ecosystem.
