1. Boil water in the water boiler (used normally to heat water for tea).
2. Let the water cool as much as possible.
3. Pour it in a glass, and place in the fridge
4. Wait a few hours and drink.
This works the best if at least 2 cups are in play. While I drink one, the other cools. Sure, not as easy as filtered water from an American fridge, but you do what you can.
Totally unrelated, and a little whiny; the children's vaccination/baby consult company is in the same building as me. All day I show people where to take their precious little babies for their shots. It's hard to watch all these people with their perfect babies, while yearning for my own.
