How do you get distilled water?

Answer 1

You boil water and trap the vapour by condense them using clean hose or tube cooled with ice or cold water. Condense vapour is your distilled water.

Or you can form a "solar distiller" by tenting plastic film over a container of water that sits over a larger catch container and place it in the sun. Such distillers that can be purchased by consumers often can produce a liter or more of drinkable water a day from a fair sized mud puddle.

How to build a box type solar still is demonstrated in the following video: www.YouTube.com/watch?v=m408EZTGD64
