In the aftermath of the Parkland mass shooting at Marjory Stoneman Douglas High School, some of the surviving students came together with their parents to form Shine MSD. The organization is devoted to promoting healing through the arts, and their latest project is a trumpet made out of bullet casings that's touring the country. It's called the "Instrument of Hope". In this World Cafe special, we meet Shine co-founders Sawyer Garrity and Andrea Peña, as well as Josh Landress who created the trumpet at his shop in New York City.
