The Statue of Liberty is an iconic blue-green symbol of freedom. But did you know she wasn’t always that color? When France gifted Lady Liberty to the U.S., she was a 305-foot statue with reddish-brown copper skin. Her color change is thanks to about 30 years’ worth of chemistry in the air of New York City harbor. Get an education on the chemistry of how this monumental statue transitioned from penny red to chocolate brown to glorious liberty green in this Reactions video.
