And now it's time for "BackTalk." That's where we hear from you. Editor Ammad Omar is back with us. What do you have for us this week, Ammad?
AMMAD OMAR, BYLINE: Hi, Michel, we got a lot of e-mails this week about the George Zimmerman verdict. A ton of listener responses, as you can imagine, and a lot of people were really angry this week. Some people were mad at the jury, some people were mad at the media for the way we covered the case.
This is TELL ME MORE from NPR News. I'm Michel Martin. Our coverage of the George Zimmerman trial verdict drew many strong reactions. Coming up, we will hear some of them. We'll dig into listener e-mail and comments in BackTalk. But first, it's time for Faith Matters. That's where we talk about matters of faith and spirituality in times of crisis, whether personal or involving the country. Many people in this country turn to faith for comfort or understanding.
This is TELL ME MORE from NPR News. I'm Michel Martin. Later we'll head into the barbershop as we do just about every Friday. We'll hear from the guys on why financial planning advice from McDonald's to its employees fell flat and other news of the week, that's later. But first, we turn to Detroit. The city declared bankruptcy yesterday, making it the largest municipal bankruptcy in this country's history. It all comes after decades of decline from the city's bloom years as the center of the nation's auto industry.
Photographer Kirk Crippens says you can't. But that hasn't stopped him from trying. Since 2009, he has been documenting the city of Stockton, Calif., which last year became the largest city in American history to file for bankruptcy — until Detroit filed yesterday. Before bankruptcy, Stockton was the epicenter of the foreclosure crisis. But before that, Crippens says, it "was an all-American city — Boomtown, USA — housing going up everywhere."
Thomas Edison famously said that genius is 1 percent inspiration and 99 percent perspiration — words that could well apply to a new machine promoted by UNICEF that turns human sweat into drinking water.
The Sweat Machine extracts moisture from worn clothes by spinning and heating them, then filters the resulting liquid so that only pure water remains. It was built by Swedish engineer and TV personality Andreas Hammar, and uses a technology developed by Sweden's Royal Institute of Technology and the water purification company HVR.
