Member Excursion: Black Sand Treasure Hunt

Saturday, September 20, 2014 • 10:30 a.m.–noon
Exploratorium Pier 15

Note: For members only

Search for elusive “black sand” (a.k.a. the magnetic mineral magnetite) at Ocean Beach. You’ll take home black sand and magnets, so you can make your own miniature Black Sand exhibit—just like the one at the Exploratorium that intrigues visitors of all ages. Tools and materials will be provided.

Preregistration is required. The deadline to sign up for any excursion is noon on the day before the excursion. Once you are registered, you’ll be contacted by our program staff regarding details such as where to meet.
