You'd have to be a pretty bad gardener to kill this on off!
Just stick it in some indirect sunlight or artificial light and off it goes without needing further help (or hindrance) from yourself!
the Original EcoSphere contains active micro-organisms, (that's red shrimp and algae to you and me) in filtered sea-water.
The EcoSphere demonstrates the delicate balance of a closed ecosystem.
Comes in various sizes and batteries are not included - not that you need any.
"Why is it pointless?"
It'll probably just collect dust on the shelf, until the dust is so thick that no light can get though to the organisms.
"Why is it cool?"
Watch things grow and be fascinated by the fact that the EcoSphere is completely enclosed.
