What Your Nose Knows invites the passerby to participate in a sensorial performance based on the sense of smell. Laure Drogoul, with her small mobile smell laboratory travels to different locations to engage the audience in a olfactory experience. What Your Nose Knows is a project about smell perception, memory and place. The artwork is variable in duration and is mobile. The performance is part of an on-going work Olfactory Factory, including an interactive Global Smell Map.
