How to humidify without a humidifier?


Robert West in upstate New York writes:

I dislike the mess of humidifiers, so in the winter I put out a bowl of water to evaporate, which helps a little. If I put out another bowl of water on the other side of the room, will I double the amount of water evaporating, or will the total remain the same?

Marilyn responds:

More water is better. To increase the effect, place the bowls on or near heat sources. Also, shallow pans work better than bowls.
