Sandra from San Antonio Palopo

Sandra from San Antonio Palopo lived in a very dark house. She doesn't
have electricity connected.
She was thrilled to receive a "liter of light" to have in her house.
This is a soda bottle half filled with water and bleach.
When installed in the roof, the natural light pours into the dark room
and lights it up.....for free!!!!
As you can see from Sandra's face she was very excited to see this!
