568. How can you make a makeshift water distiller with common materials? - VL
To distill water, you need to condense steam on a cold surface and collect the condensate. You could boil water in a teapot and allow the steam flowing out of its mouth to pass across the underside of a clean metal bowl full of ice water. The steam would condense as pure distilled water on the outside of the bowl. If you then placed a clean cup under the metal bowl, the distilled water would drip into that cup.
