Step 1: Finding Water in the Wilderness Without a Stream or Running Water
For this instructable, we're assuming all you have is a lighter (or matches), a piece of string and an empty water bottle. Any container will do as long as it holds water.
If you can't find a stream or source of running water, look for a mud puddle. If you can't find a mud puddle, try to dig a hole deep enough so water seeps in the hole.
NOT SHOWN: As an added way to filter the dirt, you can place a shirt or piece of material over the opening on the bottle and use it as a filter to prevent large pieces of dirt from entering the bottle as you fill it.
Fill the container with water from the hole.
Step 2: Tie the String to the Bottle
Step 3: Start a Small Fire
Step 4: Hold the Bottle of Muddy Water Directly Over the Flame
Keep the bottle over the flame until it begins to boil. Let the water boil for several minutes to kill any germs or bacteria in the muddy water.
Step 5: You Can Now Let It Cool and Drink the Water
