Distilled Water on the Stovetop
Boil tap water in a covered pot and catch the steam that condenses on the cold, upturned lid. The steam leaves the dissolved salts and minerals behind, so the drops that fall into a bowl in the middle are distilled water: for steam irons, lead-acid batteries, chemistry, humidifiers and topping up anything that must not scale.
It is slow and uses a lot of energy for little water. The notebook shows why, and how to measure your own stove.

Set up the pot
Set up the pot
Stand a trivet in the stockpot and a glass bowl on it. Pour tap water around the bowl to about 5 cm below the bowl's rim, about 4 litres; none may splash into the bowl.

Turn the lid over
Turn the lid over
Put the lid on upside down, handle down, so it slopes to its centre over the bowl. Steam will condense on its underside and run to the handle and drip into the bowl.

Simmer
Heat until the water simmers, then turn down so it keeps a gentle simmer. A hard boil throws spray into the bowl. Start the stopwatch at the first drip.

Ice on the lid
Ice on the lid
Fill the upturned lid with ice. The colder lid condenses more steam. When the ice has melted, ladle the meltwater off with oven gloves on and add fresh ice.

Stop before it runs dry
Stop before it runs dry
Stop while at least 3 cm of water is left in the pot: what stays behind holds all the salts. Turn off the heat, let it cool 10 minutes, and lift the lid away from you; steam scalds.

Weigh and test
Weigh and test
Weigh the distillate and note the time. Read a sample of the tap water and of the distillate with a TDS meter: the distillate should read far lower. Enter your numbers in the notebook.

What it removes, and what it does not
What it removes, and what it does not
Distillation leaves dissolved salts, minerals and most dirt behind in the pot. Substances that boil at or below water's boiling point can travel with the steam, so it is not a guaranteed way to remove solvents or fuels from contaminated water. Laboratory stills use the same principle with a water-cooled condenser, which is faster and uses less ice.
