Holographic Chocolate: The Secrets of Structural Color

In–Person Workshop

Location: Harvard Museum of Natural History, Classroom B (Third Floor)

Instructor: Kathy Liu, PhD candidate | Aizenberg Biomineralization & Biomimetics Lab

Price: $30 members / $35 nonmembers

In nature, brilliant colors appear in myriad places—along the surface of a bubble, on butterfly wings, after a rainy day, or through a windowpane. Remarkably, many of these hues don’t involve any chemical dyes or paints. Instead, these colors originate from the internal material structure and their interactions with light. This workshop will dive into the world of “structural color,” zooming in on fascinating structurally-colored materials in nature with microscopes and zooming out to applications of structural color for next-generation materials. As the finale, workshop attendees will craft holographic rainbow chocolate to take home. No prior science background is required to participate in this class. All attendees must be 18 or older.
