They can choose to: Produce at least one natural dye, modifying it’s colour and mordanting it in different ways to dye at least 2 different categories of fibers. Explore dyeing with bacteria of different fibers and bacteria.//** grow kombucha in a container to make leather === Inspirations & References === [[http://www.abc.net.au/news/2016-07-31/kombucha-tea-scientists-designer-work-to-make-clothing-textile/7674892| Kombucha clothing: Scientists, designers work to make fermented tea into a textile]] \\ -------- \\ ==1/Measure quantities of tea and sugar == {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_38_.jpg?200x200|}} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_1_.jpg?200x200|}} ==2/ gather the ingredients== 6g tea and 600 ml sugar mix with the amount of hot water needed to fill the container {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_28_.jpg?200x200|}} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_24_.jpg?200x200|}} ==3/Sanitize the container== {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_25_.jpg?200x200|}} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_26_.jpg?200x200|}} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_27_.jpg?200x200|}} ==4/Wait until the temperature drops to 25 degrees Celsius== {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_34_.jpg?200x200|}} ==5/plunge the scooby into the container== taking care to keep the starter liquid and pour it into the container at about 25 degrees Celsius. {{vimeo>253038749?200x200}} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_30_.jpg?200x200| }} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_32_.jpg?200x200| }} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_33_.jpg?200x200| }} {{:fabricademy2017:students:julie.taris:julie-taris-biofabric-kombucha-_36_.jpg?200x200| }} ==6/Calculate the ph of the water == Add vinegar if you want to acidify your bath. 3 PH is good and plays an important role in protecting the SCOBY from microbial invaders.
