But then I met a biologist, and now I think of materials like this -- green tea, sugar, a few microbes and a little time. I'm essentially using a kombucha recipe, which is a symbiotic mix of bacteria, yeasts and other micro-organisms, which spin cellulose in a fermentation process. Over time, these tiny threads form in the liquid into layers and produce a mat on the surface. So we start by brewing the tea. I brew up to about 30 liters of tea at a time, and then while it's still hot, add a couple of kilos of sugar. We stir this in until it's completely dissolved and then pour it into a growth bath. We need to check that the temperature has cooled to below...
