A functioning self sustaining ecosystem within a globule of water, which could be sustained for live durational projection [without intervention of a video-microscope]. Microorganisms and daphnia obtained from a small temporary pond, were enclosed within a small globule of water. The lens shape of this droplet, and its self magnifying properties combined to create a projection microscope.



The addition of the (halogen) light source unit provided a substitute for sunlight; although this also produced very high temperatures. Made from a micro-fiche viewer, pie tin, and a heat resistant glassfrom old slide projectors, a large sweet jar exposed to a halogen light.
Fresh algae rich water circulated into the pie dish along a tube. Cool water was circulated around this, and an air block infused the water with extra air.



The point of this work was that the observation device itself, became both life threatening and the source of "energy input into the system" the light frequencies from the halogen bulb are similar enough to sun light to facilitate photosynthesis.
