Join us for a special Presentation and Exhibition Preview introducing our two new Spring and Summer exhibitions: Inside the Faraday Cage: The Science of Things That Aren’t So and A Tale of Two Pianos.

Be among the first to experience these new installations ahead of their public opening. Curatorial Director John Leysath will present on Hammond’s 1951 Faraday cage experiments, while Assistant Curator Donovan Lafontaine offers an introduction to the piano exhibition.

Inside the Faraday Cage features a life-size, non-working replica of the experimental apparatus, inviting guests to step inside and explore Hammond’s investigations into ESP alongside physician and parapsychologist Andrija Puharich and psychic medium Eileen Garrett.

Museum Members and VIP guests enjoy complimentary admission.
A $15 fee applies to the general public. Reservations are required. Space is limited.

Looking for a unique and engaging summer program? GMGI’s Summer STEM programming is now accepting registrations!

Our Summer STEM programs are one-week courses designed to give students hands-on science experience in a biotechnology laboratory.

We are thrilled to announce that this year, we are partnering with Maritime Gloucester for our new program, From Harbor to Helix: Training in Environmental DNA. During this one-week course, students will dive into authentic marine science by collecting environmental samples using hands-on sampling techniques. Back in the lab, students will analyze their samples using industry-standard biotechnology methods, including micropipetting, DNA extraction, gel electrophoresis, PCR, and DNA metabarcoding. This immersive experience connects fieldwork to cutting-edge molecular biology, giving students a firsthand look at how scientists study biodiversity and marine ecosystems from sample to sequence.

The course is taught by Gloucester Biotechnology Academy and Maritime Gloucester staff, and does not require any previous science or lab experience. Each student will have ample guidance and support in these real-world investigations.

Registration is open to rising 9th graders through seniors who graduated in 2026 who are interested in real-world science and learning in a hands-on environment.
