Thank you for the article. I also explained the properties and benefits of water to my children myself. My children are 6 and 12 years old. The youngest child often asks some unusual questions, recently asked why different water tastes different, how exactly the sewage system is arranged, etc. The older child is already asking questions about water conservation. She heard somewhere in the news about resource depletion and asked me what she could do to conserve it, that was very nice of her. She even often reads some articles about water on Waterzen.com herself, about ecology. I'm glad I have such conscious children growing up.
