Ever wanted to make your own paper or plastic? Or create leather that doesn’t use animals? Why not try collaborating with microbes — tiny microscopic organisms — to design and grow a custom biomaterial at home! This biomaterial is made by the millions of living yeast and bacteria that normally work together to produce kombucha, a fermented tea. But, depending on what you feed your collaborators, they can also grow interesting and different pieces of biomaterial for you! Share the amazing biomaterial you grow with us! How are you using your biomaterial? What did you feed your microbes?
