My weekend project:
My first attempt at a completely sealed ecosystem (biosphere) including the ever brave Aquanaut! (Ghost Shrimp)…
It was a fun little project I read about back at MAKE Magazine Issue 10… It’s quite cheap (I recommend Hobby Lobby for the sealable glass containers)… the shrimp and snails you can get for free from a pet store if you bargain to buy the hornwort, neutralizing salt, and calcium carbonate… You can find the duckweed, other important organisms and soot from your local pond…
And the aquanaut from the smaller container, Diomedes, a brave young soul who runs around all day long in circles
The aquanaut in the larger container, Odysseus, was unavailable for photos…
Here are the instructions:
