This water purifier works by having salt water inside evaporating from inside then sliding down the side and out the hole without all the salt making it perfectly clean good to drink water.

Step 1: Preparing the Milk Jug

First make sure you wash out the milk jug with hot water.

Step 2: Making Water Slot

Cut a square out of the side of the milk jug, then cut down deeper on the left and right hand sides and bend it inward.

Step 3: Cutting the Cap

Cut a large round hole in the top of the cap.

Step 4: Plastic Wrap

Cut a small square of plastic wrap and put it over the hole in the cap. (it doesn't have to be taped/glued because when you pull it tight it doesn't fall off but taping or gluing it is a good idea)

Step 5: Putting It All Together

Screw the cap on to the bottle and you're done!! If you want to test it put some water with salt in it that you've tasted and made sure tastes like salt water. Then put your cup or container next to the hole in the side of the jug and put it in the sun! : )
