In 1960, David Latimer planted a tiny garden inside of a large glass bottle and sealed it shut. He opened the bottle 12 years later in 1972 to add some water and then sealed it for good. 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.
