This Water Bottle Folds to Become a Roof Tile

Most water bottles—the disposable kind you grab from the gas station’s fridge—end up in landfills, though they’re really recyclable. It’s one reason cities, such as Chicago, started taxing water bottles. And while such taxes do curb the sales, they don’t eliminate them all together.

In order to do something useful with all those plastic bottles, entrepreneur Donald Thomson created ‘A’Gua water bottles in Costa Rica. Though he never used to drink from plastic bottles himself, he wants to use the product—once they’re empty of water—as concrete-and-waste-paper-filled tiles.
