With the 10th anniversary of the Sept. 11th attacks coming up, the memorial site at ground zero ran a test on one of the reflecting pools.
The two pools, each in the footprint of a tower, are an acre in size and 50 feet deep. They're the largest man made waterfalls in America.
What a beautiful way to honor all those we lost.
The memorial officially opens on September 11th, 2011. See the above video for more details about the site.
