World's Smallest Aquarium
How small is Russian artist Anatoly Konenko's microminiature aquarium? Well, for starters, it holds just two tablespoons of water. Not that you could ever fill it with a spoon, of course! The force would tear the décor to bits. Konenko favors a syringe for that particular task.
Konenko, who uses a microscope for most of his work, currently also holds the Guinness World Record for making the world's smallest book.
