This video shows the build of a Emergency Water Distillation Portable Still that removes biological, salt and heavy metal contamination from drinking water.The still is made by putting an upside-down stainless steel funnel over a pot of boiling water as a lid. Ideally the pot is designed for cooking, but in an emergency any metal container, such as a soda can, may be used. Connect a 1/2 inch diameter copper pipe to the funnel with three 45 degree elbow fittings. Put a damp rag on the pipe to condense the steam. Fresh, drinkable water will drip out of end of the pipe.
