Made with over 100,000 toothpicks over the course of 35 years, this sculpture of San Francisco, created by Scott Weaver, features multiple ping-pong ball runs that allow you to “tour” the sights in different parts of the city. Weaver’s sculpture will be on display at the Exploratorium when we reopen at Pier 15 on April 17, 2013.
