Something is living in your showerhead. Scientists need your help to figure out what it is, and why it’s there. Biologist Noah Fierer is enlisting people around the country to search out the tiny, microscopic life in showers. Find out what happens when Lindsay and Marshall sign up as citizen scientists, and turn their bathroom into a lab.
