Recycling the Sound of Music

The village of Catuera in Paraguay is literally built on a garbage dump that grows by more than 1,500 tons of solid waste each day. The people, including children, who live around this trash heap survive by sorting and recycling the garbage.

Several years ago, Favio Chavez, an ecological technician who worked at the landfill, befriended the poor scavenger families and became acutely aware that the children who worked on the trash pile yearned for something uplifting in their lives. He decided to share his love of playing music by teaching the children to play instruments. At first, Chavez used his own musical instruments to teach them, but so many children wanted to learn that he tried cobbling violins and cellos out of oil cans, jars, scrap wood, forks and other junk to give them something to play, After about four years of experimenting, Chavez and his team began discovering which materials created the best sound. The result is a youth orchestra, now 30 members strong, that produces the sweetest sounds from their recycled instruments. Recently their story has been turned into a documentary, directed by Graham Townsley. It’s an inspiration on many levels.

Oberhausen’s Slinky Springs Bridge

If this bridge in Oberhausen, Germany, reminds you of a slinky toy, that’s exactly what inspired it. German artist Tobias Rehberger spiraled 496 coils around a rainbow colored walkway that crosses over a canal to connect two existing parks. Rehberger collaborated with structural engineers Schlaich Bergermann and Partner to realize his design. The structure consists of pre-cast concrete plates, spiral bars and railing made of steel and net cable, all attached to high-strength steel stress ribbons connected to the inclined supports on both sides of the canal. The 1,332 foot walkway has a synthetic finish that kind of bounces when you walk. It is presented in 16 different colors, matched in color on the underside of the bridge which is made out of a different material. The Slinky Bridge is luminous with color and definitely puts a spring in your walk.
