Time for the "Shoutout."
Which of these U.S. cities is oldest? You know what to do.
Is it Baltimore, Maryland, Pittsburgh, Pennsylvania, Chicago, Illinois or Savannah, Georgia?
You've got three seconds, go.
Founded in 1729, Baltimore is the oldest U.S. city on this list.
Its harbor connects to the Chesapeake Bay.
That's your answer and that's your shoutout.
The Frigate Constellation,the first ship of the U.S. Navy launched in Baltimore Harbor.
The Battle of Baltimore inspired Francis Scott Key to write the lyrics to the "Star-Spangled Banner."
Despite its reach history, Baltimore Harbor's also been rich in pollution.
At one point, it was labeled un-swimmable and unfishable.
The new installation is helping to change that.
The water will powered trash in receptor's purpose is to collect all of the trash and debris that comes down this river,and this river drains a big part of Baltimore City and Baltimore County.
And now that our children can't swim in the harbor or the streams feeding the harbor because it's polluted.
It works from river current and solar power.
The river current itself brings the trash to it,lows on the conveyor.
The conveyor is powered by the water wheel, it's really like an engine.
So far it's collected over 100 tons of trash in the four months that it's been in here.
It's almost all cigarette butts, plastic bottles.
We get plastic bags, chip bags.
There is needles, there is, you know, sewage.
We can pick up as much as 40,000 pounds a day.
