Remember this classic quacker? No batteries or remote required—just wind it up and let it ride. Pick up the tin duck on a bike ($12) at San Francisco's Zeum, an art and technology museum with a flair for kids' fun. Visitors can get creative at a DVD Claymation station or take a spin on a century-old carousel before browsing the museum shop for other retro playthings. (415) 820-3320, zeum.org.
