If you've ever dreamed of owning your own tabletop biosphere, or looking for a fun project either to display in your home or give as a gift, look no further. Here are some resources to creating your own living biosphere ...

Make Magazine's online labs have put together some great resources on how to create your own biosphere. This guide, detailed in a PDF, shows how to create one that is home to a shrimp. For those who aren't familiar with what a tabletop biosphere is, the non-ecologist definition is basically a sealed living system (with the exception of light) designed to maintain and balance itself in terms of gas, nutrients, etc., and something that is generally composed of a glass jar, plants, and microorganisms. This version will supply the shrimp with food, oxygen and help process its waste.

Other biospheres can be made without a shrimp, consisting of just plants, water and some specialized chemicals. This video podcast will show you how:
