Ethiopia’s Omo Valley | Africa’s Last Frontier, National Geographic Magazine: Nails Meant for a School, Used as Adornment | Omo Valley, Ethiopia

There were some interesting developments between our two trips to Labuk village. The government built a school and for the first time nails were available.  No one goes to the school but the locals took the nails and put them in their chins as decoration, and they also use the hole in their chin to squirt out water to wash their hands.
