NOTE: This is a method of filtering water – not purifying it! While the method is really cool, you should always use water purification tablets or boil your water before consuming, unless there is no other choice!
Water is the lifeblood of all of us.
You can last about three to four days without any water at all, although you will start to see a rapid decline in bodily functions and capabilities before that!
That means in a survival situation, after securing a safe shelter, water has to be at the top of your list.
But if you are in the wilderness or infrastructure has broken down, finding drinkable water will be a challenge.
Fortunately, if you have a plastic bottle with cap, a retainer vessel, gravel and fibrous material (like paper towels, clothes, tissues) you have what you need for filtering water in an emergency situation.
The video on the next page will show you how.
