OV has a terrarium in a bottle, this can be found on the windowsill in Center of Excellence. The terrarium is sealed, with the intention of making it a closed cycle of water and nutrients that can hopefully survive the potential lack of love from future board members. It is not quite a biosphere, but more or less spheroid in shape. In theory there are two closed cycles:
A mix of white gravel and activated charcoal. Stores water and filters out pollutants.
A layer of mostly dead moss. Serves as biomass and nutrient source.
A mixture of organic matter, minerals, gases, liquids, and organisms that together support life. The soil in question is a mix of "plantejord" from Plantasjen and dirt from Gløshaugen.
Various plants have been introduced to the terrarium. Since soil and samples from various sources including outside have been introduced, it is assumed that a variety of microorganism live in the Biospheroid.
