Admit it: Hasn't the Godzilla inside you always wanted to grab the Golden Gate Bridge and shake it silly? Finally, you can. In honor of the iconic span's 75th birthday, Exploratorium exhibit developer Dave Fleming presents a dynamic model of the Golden Gate Bridge. What happens to the bridge during an earthquake? How about strong winds and heavy traffic? The model dances and wiggles realistically, displaying the same vibrational modes and motions that occur in the actual bridge.
