Inside these sealed glass balls live shrimp, algae, and bacteria, all swimming around in filtered seawater. Put it somewhere with some light, and this little ecosystem will chug along happily for years, no feeding or cleaning necessary, totally oblivious to the fact that the rest of the world exists outside.
we used to have these guys at anthropologie. they perched on the register counter and EVERYONE who passed them by touched, poked or shook this small world like a snow globe. ecospheres are pretty amazing though..
