This project is a public installation that acts as a bank and station for the biological sharing between dogs and humans. It is an integration of collection, production, and distribution of dog microbiota. It consists of 3 parts: the bottom part acts as a dog playground, which can collect skin microbes from dogs. People can also drop in dog stool in the middle part, where the production of microbiota samples happens. After the whole process, the microbiota bubbles will be released from the trumpet in the top part. The production process involves different steps, from sampling, dilution, colonies, purify, to quality check, fermentation, centrifugation, freeze drying, and integration. Whenever people drop in dog stool, the machine will be triggered to release bubbles that contain beneficial dog microbiota, which can be screened, assessed, and selected through the evolution process.
