In a beautiful example of a closed but functional ecosystem, David Latimer has grown a garden sealed inside of a giant glass bottle that he has only opened once since he started it almost 54 years ago. He placed some compost and a quarter pint of water into a 10-gallon glass carboy and inserted a spiderwort sprout using wires. In 1972, he opened the garden again to add a bit of water. With that one exception, the garden has remained totally sealed – all it needs is plenty of sunlight!
