Through collaboration with a public biology laboratory ‘Biolab Seoul’, it was aimed to create content that anyone can experience and become interested in bio-material, mycelium. The mycelium consumes agricultural waste to grow into the desired shape, and has a white texture as a drawing paper. That characteristic has led to design masks that everyone used to decorate or play with when we were young. There are 5 masks designs inspired by the natural shapes of various mushrooms. Biolab Seoul has been working to introduce various bio-materials to the public in the form of workshops. Workshop has the advantage of learning new things since it provides opportunities for active experience regardless of online and offline channels. As one of those workshops, mycelium mask can provide the experience of the material’s features by playing with it.
