How cool is this, a very simple water distiller that will turn dirty or salty water into fresh, clean, drinkable water with supplies you most likely already have at home. In the video posted below is an example of a small scale system made only using a plastic bowl, a cup, plastic wrap, a rubber band and a rock or weight.
This simple technique can be expanded to be larger to clean much more water if needed. Take this info and keep it in mind, you may need it one day if the water grid goes down or becomes contaminated. This is also a good idea when camping or out in the wilderness to lighten your pack weight.
