Ok so I saw a show on tv the other day that was talking about how distilled water will not boil like tap water will. They heated it up and it stayed calm, that is until they added an impurity(in this case sugar) and it immediately "exploded" into a boil. So I was just wondering what might happen when using distilled water in a cooling system (w/o antifreeze). Could it be... Nothing? A catastrophic explosion that kills 12 ppl? Or an 87.3hp gain? or what?
