NOVA: Mystery of the Senses - Smell

This video explores the many exotic smells circulating in the world around us. Who better to understand about the sense of smell than Sophia Grojsman, a master perfume designer. Grojsman invites us into her perfume lab and explains the way a successful scent is born. An effective perfume incorporates a delicate blend of top notes, middle notes, and bottom notes. Next, we follow our noses to sample a rainbow of scent, from frankincense and truffles to sweaty locker rooms.
