Wondering how this works? Well....the contaminated water will go into evaporation because of the sun, the evaporated water will collect in the other bottle giving you fresh water.

I really like this instructable. Short, and to the point. It's one of those things I'll file away in the back of my mind for some day.

Put some foil in an arch under the dirty water bottle to focus the sun's rays.  This'll help the evaporation rate.

I liked it. 4 stars cause it was a bit short.

lay a rag or something over the empty bottle and the lower temp. will increase the condensing action and shorten the time of distillation.
