This neat DIY project will allow you to transform salt water into drinkable water. You can use containers of various sizes depending on what you intend to do with it. You could have a smaller, portable device that you carry in your vehicle and have a larger one at home. This will be especially useful if you live close to a large body of salty water. This project, in particular, will produce about 1/3 of a cup of drinkable water per hour.
Step 1: Materials
- Metal can
- Empty soda can
- Aluminum foil
- 2-3 ft of tubing
- Rubber band
- Towel / paper towel
- Hot glue gun
Step 2: Salt water canister
Remove any labeling from the container and the lid. Cut four tin foil squares of about 3 X 3 inches each.
Wrap three squares around the top of the metal can. Fold the foil sheets nicely around the edges of the can. Tie them all together with the rubber band and place the 4th square on top.
Step 3: The tubing
Start by making a hole in the foil with the scissors. Insert the tubing in the hole about 1/3 inches deep. Seal it up using hot glue or something similar.
Step 4: The collector container
Cut a square of foil larger than the top of the can. Just like you did with the other container, fold the foil by wrapping it around the edges of the can. You can use less foil here than you did on the other container. When you’re done, make a hole in the foil on top of the can’s opening. You don’t want to make it too large, just make sure you’ll be able to put the tube through.
Step 5: Using the Purifier
Connect the two containers using the tubes and you’re done. It should look roughly like in the picture below.
To use it, start by putting some salt water into the large container. As it heats up, it will expand so you make sure you don’t fill it more than halfway up. Build a fire underneath. You can use a stove or build a regular fire using twigs and branches.
Make sure that the tubes are properly connected to each container. As soon as the fire starts burning, place a wet paper towel around the tube. Make sure the towel stays damp or wet at all times. It will take about 5 or 10 minutes for the purifier to start producing water. As water boils, all bacteria and pathogens are killed. The paper towel helps cool down the steam and turn it back to pure, drinkable water.
