︎︎︎ONION OPTICS In an oddly poetic act, moths will on occasion drink the tears from the eyes of a sleeping bird. Sounds harmless, but this rare interaction is an unmistakably one-sided affair. Scientists actually have a word for this unique tear-feeding behavior, which they call "lachryphagy." Onion optics is a project about tears initiated in a workshop with Dutch artist and designer Karel Martens. I made a series of glasses to collect and analyze various reasons for crying and discovered that, under a microscope, a tear of joy has a different salt pattern than a tear from an onion or from sadness would form.
