I just watched this video seconds ago elsewhere. Pretty amazing if you ask me. I like the fact that Bill gates took just a little sip lol

So which water should we truly be afraid of? I would put money that the water coming out of that machine is cleaner. However, distilled water lacks key minerals (salts) that the body needs.
