Believe it or not, David Latimer has successfully grown and kept a garden sealed inside of a giant glass bottle that has been opened only once since creating it nearly 54-years-ago. He first planted the garden on Easter Sunday in 1960, placed some compost, added a quarter pint of water, and then inserted a spiderwort sprout using wires into a 10-gallon glass carboy.

According to The Daily Mail, "The bottle garden has created its own miniature ecosystem. Despite being cut off from the outside world, because it is still absorbing light it can photosynthesize, the process by which plants convert sunlight into the energy they need to grow. Photosynthesis creates oxygen and also puts more moisture in the air. The moisture builds up inside the bottle and 'rains' back down on the plant. The leaves it drops rot at the bottom of the bottle, creating the carbon dioxide also needed for photosynthesis and nutrients which it absorbs through its roots."
