1 day after people, in the rotunda of the National Archives Building, the United States Constitution is now on permanent display, with no one to take the document on its nightly journey to the security vault. The parchment is preserved in a shatter-proof encasement filled with Argon. Argon is an inert gas that replaces Oxygen and moisture in the air that would cause damage to the document over time, how long can it protect one of America’s most precious treasures?
250 years after people, centuries without maintenance have caused the rotunda of the National Archives has collapsed, exposing the US Constitution to the elements. Still protected in it’s encasement, wind and rain are the biggest threat, it’s sunlight. The damaging ultra-violet rays cause ink to fade, and within a few years the words are erased from history.
