This woman invented the World's Worst Smell! Can you guess what it is ? I sat down with Dr. Pamela Dalton, cognitive psychologist at the Monell Center of Chemical Senses and Guinness Book award winner to talk about her invention-- the worst smell ever. I caught up with her on a recent visit to Cincinnati. She shared how our sense of smell and taste work, and how she used what she knew about science to make the world’s worst odor! Fun fact: Her favorite scent is diesel!
