Distiller!

A flat-bottomed flask on the stove top. My kitchen looks like a lab =) It's my experiment. Didn't want to spend too much money on it. Although I believe water is the primary source of energy for the body and it's worth investing even a small fortune, I can't afford 1500 euros to buy an automatic glass distiller. And I didn't want to buy a plastic one. Well, I may give it a second thought now as it takes a lot of time (and cold water) to get just 1 litre. ~2h
