This is the original EcoSphere, the      world's first completely closed ecosystem      - a complete self-sustained miniature      world encased in glass. The perfect gift      or purchase, this unique mini-aquarium      originates from a technology-transfer by NASA.      It is not just a scientific breakthrough, but a perfect work of      art. Easy to care for, Ecosphere is a fantastic teaching-tool,      which provides a view at life on our planet and the      technology of future space-travel.
