Survival Skill Spotlight How To Build A Solar Still For Drinking Water

---

When stranded in the wild, especially in arid or coastal regions, access to clean drinking water can mean the difference between life and death. One often-overlooked survival technique is building a solar still—a simple yet effective way to purify water using the sun’s heat. Whether you’re dealing with salty ocean water, contaminated sources, or only have moisture from plants, a solar still can be a lifesaver. This method uses evaporation and condensation to collect purified water without the need for fire or complex tools.
To build a solar still, you only need a few materials: a clear plastic sheet, a container (like a cup or bowl), and a shovel. First, dig a hole in the ground, place the container in the center, and fill the space around it with moisture-rich materials like leaves, wet cloth, or even urine in extreme cases. Cover the hole with the plastic sheet and seal the edges with soil or rocks. Place a small stone in the center of the sheet to create a dip—this directs the evaporated water to condense and drip into your container. It may not yield much water, but it’s clean and drinkable.
This simple device demonstrates the power of survival knowledge and nature combined. While a solar still won’t replace a steady water supply, it offers critical hydration in emergency situations. Practicing this technique before you need it boosts your chances of survival—and teaches valuable lessons in resourcefulness and self-reliance in the wild.
