Retrieve a discarded water bottle. Tear off the label and fill with any water that’s not too murky from a creek, standpipe, or puddle. Place the bottle on a piece of metal in full sun. In six hours the UVA radiation will kill viruses, bacteria, and parasites in the water, making it safe to drink. Clever.
