“TinkerFest is an annual celebration for all ages,and it’s all about tinkering and making,” says Chabot deputy director Liz Osterman.“We always do tech, take apart a car, and the whole idea is that kids can experience real tools and be able to explore and engage in different ways.”

Other activities included Lego robotics, wearable tech, scraper bikes, live music, planetarium shows and more.
