The collected bottles were stuffed with trash and used to form the walls for a classroom addition at a school in Granados, a small mountain town in the Baja Verapaz region of the country. Amazing.
This video shows how the project was done. The music is a fitting addition to a project that brought the widest smiles to dozens of faces.
Imagine what might happen if similar projects happened on a massive scale world wide. There are a lot of plastic bottles on the planet.
