Happy 250th! Our museum will be OPEN 10am–7pm on July 3 and 10am–5pm on July 4.

Curious Histories Fest is back! Our free annual celebration of science, history, exploration, and experimentation will feature free hands-on activities and family-friendly fun, as well as exciting talks, tours, and highlights from our special collections. Visit our museum; talk to curators and experts; take part in performances, story times, and special events; and immerse yourself in curiosity! Plus, the first 150 visitors will receive a free serving of Siddiq’s Water Ice (limit one per person).

Color Your World

Curious Histories Fest highlights a new theme each year. Inspired by our current BOLD: Color from Test Tube to Textile exhibition, this year’s “Color Your World” theme explores the color in your life.

Have you ever wondered about the color of your clothes? Or your food? Does color have a taste? How do we perceive color? Where do natural and synthetic dyes come from, and how do they work? Do you love tie-dye? And rainbows?

Join us for family activities, hands-on crafts, engaging talks, and live dyeing demos! Then visit our museum and see special collections showcasing strange and wondrous color and dye histories. Enjoy food trucks, special guests, live music, and so much more.
