Inside San Francisco’s Museum of Craft and Design, a long hallway painted eggshell blue is lined with the most extraordinary devices. A glass globe that uses trained bees to detect the presence of disease in a person’s exhalations.

A USB-powered silver necklace that gives off a scent—fragrances include “fascinate,” “annihilate,” and “carouse”—when its wearer’s heart rate tops 110 beats per minute. All the items are here as part of Living With Scents, the museum’s first olfactory exhibit. Read more of Zara Stone’s article for Fast Company here.
