CTDL 148: A home-made biosphere

I’m hoping to do this with my kids this spring/summer.

We started with a Table-Top Biosphere, or as MAKE called it, a “Tabletop Shrimp Support Module” or TSSM. The whole idea is to create an entirely self-sustaining aquatic ecosystem within a completely sealed jam jar. If you do it right, your freshwater shrimp “aquanaut” will be able to survive for months without your ever needing to feed it or even open the jar. The ecological balance you create supplies all the air, filtering and food for all the creatures within the jar to survive in perfect harmony. If only the real world was this easy.
