Just go and buy a few shrimp, stick 'em in a jar and have done with it.
Eco-Jar. Cheaper. Doh!

Not quite. If you stick them in jar you still have to feed them. The idea
of the eco sphere is that it is a completely balanced ecosystem in there.
No outside intervention such as feeding is needed.


I thought I'd mention it as I remember a childrens' science programme -
I think BBC's Science Shack - where they housed a few woodlice in a jar
with soil, air and a few plants. The jar was sealed and never opened.
The only thing the ecosystem needed to sustain it was light and heat.
