80-Year-Old Man Hasn’t Watered This Sealed Bottle Garden Since 1972 And It’s Still Alive.
David Latimer planted the terrarium garden on Easter Sunday in 1960. He placed some compost and a quarter pint of water into a 10-gallon glass carboy and inserted a spiderwort sprout, which is not typically an indoor plant, using wires.
In 1972, he opened the plant terrarium again to add a bit of water. With that one exception, the garden has remained sealed – all it needs is plenty of sunlight!
The self contained ecosystem has flourished for nearly 60 years.
For those who are wondering how this is even possible: the garden is a perfectly balanced and self-sufficient ecosystem. The bacteria in the compost eats the dead plants and breaks down the oxygen that is released by the plants, turning it into carbon dioxide, which is needed for photosynthesis.
The bottle is essentially a microcosm of earth.
