He’s Alive! Mini complete Aquarium

Try to imagine a mini Aquarium where you never need to feed its people and you never need cleaning. It would seem an object from the Harry Potter Saga, but it is. It is a new concept of a self-sufficient ecosystem that fascinates both young and old. Arousing the curiosity of all those who see it but mostly allows more young ¹ ran assemble one after another the elements that compose it and then say “this ecosystem I did it!”.

DIY autonomous aquatic ecosystem with shrimp

Is Alive! It’s a do-it-yourself aquatic ecosystem ecological plastic PET, provided all the information necessary to be able to directly create at home or at school: small spores of micro algae produce oxygen and food through the process of photosynthesis. The shrimp they use the oxygen and eating the micro algae generating carbon dioxide. In turn this is reused from micro algae that reshape in food and air.
From the outside it must reach only the light (of day or electric) and air (once a month).

Every biosphere with shrimp is a unique, no two are identical!
