People are always filtering, purifying, and even distilling their water to make it as pure as possible. Of course, it's a good idea to get rid of germs and toxins, but what if we achieved perfectly pure water, with nothing but H2O? That might not be such a great idea. David Rees talked with a water scientist named Kim at ThermoFisher Scientific about the properties of pure water. Kim really needs a last name because she has the best line in the video.
As far as drinking ultra-pure water, it’s not something we need to worry about. The water made in this lab is not comparable to water available to the public. And drinking distilled water will only hurt you if that’s the only water you consume and you don’t make up the difference in minerals with the food you eat. -via Boing Boing
