I needed the reminder. I'd forgotten that, but myth busters says it needs to be distilled water. They also said they couldn't rule out it being possible for other liquids.

I never trusted a microwave and avoid using it, but I do sometimes and could see me making that mistake. I have a gas stove that heats things quick enough.
