Catching a Drink
Finding Clean Water
Use any containers laying around and set them out to try and catch any rain water that falls. You can use large leaves to catch raindrops and funnel them into containers.
On The Island:
A good place to find water is by venturing island. The further you travel towards the middle, the better your chances of finding a water source. If the island is large enough, you might find streams and waterfalls that will provide fresh drinking water.
If you have access to a pot and either a stove top or a fire, you can boil any water you find (including ocean water) to make drinkable water. Boiling is the most certain way of killing all microorganisms. Water temperatures above 160F kill all pathogens within 30 minutes and above 185F within a few minutes. To be safe, let the water boil rapidly for one minute, especially at higher altitudes since water boils at a lower temperature
Solar Water Still:
If there's no rainfall or fresh water on the island and you have a sheet of plastic available, then you can make a solar water still.
Create a Solar Water Still:
Step 1: Dig a hole in the sand up near the edge of the trees. You want to dig deep enough that the hole is within the damp sand underneath.
Step 2: Place a container in the center of the hole.
Step 3: Fill the gaps surrounding the container with anything wet, such as wet leaves.
Step 4: Place your plastic sheet over the hole and anchor the sheet in place with larger rocks around the edges of the hole.
Step 5: Place one small rock in the center of the plastic, just over the container.
Step 6: Condensation will occur on the underside of the plastic and run to the center. It will drip into the container filling it with distilled drinking water.
