Groupon offers the Small Aquatic Ecosystem Sphere (pictured) or Pod for $49 plus $5 for shipping. That's $30 off and the lowest total price we could find. This glorified fish bowl was developed by NASA and includes microorganisms, shrimp, algae, and bacteria that feed off and sustain an independent ecosystem (for about two years). Deal ends August 27.
