Step 1: Materials
1) A 5-gallon bucket or another similar sized container
2) A small towel or rag (in an emergency this could be a shirt or a rag also)
3) A cup or a smaller container that will fit easily inside the larger container or bucket
4)A plastic tarp or a large piece of plastic rap
5)A bungee cord, paracord, or other tie that fits around the larger container
6) A rock, about 1-2 inches in diameter, or another small, weighted object such as a few bolts or bolt nuts.
Step 2: How to Build the Kit
First, get the towel very wet and place it in the bottom of the larger container, wrapped around the bottom with a space in the center.
Place the smaller container in the middle of the towel.
Then, cover the larger container with the plastic and tie the outside to keep it sealed.
Place the rock (or another small, weighted object) in the center of the plastic directly above the smaller container.
The water from the towel will evaporate onto the plastic and drip off of the point that drops down because of the rock. This works the best in hot weather. The water that ends up in the cup will be much cleaner than the water stored in the towel since water leaves behind dirt and sediments when it evaporates.
See the introduction picture or the next slide for a diagram on how to put the kit together.
