Why is the Statue of Liberty Green?

Did you know the Statue of Liberty wasn't always green? When France gifted Lady Liberty to the U.S., she was a 305-foot statue with reddish-brown copper skin.

Get an education on the chemistry of how this monumental statue transitioned from penny red to chocolate brown to glorious liberty green.
