Watering Water

One of the things that is needed is water for life. It's a known fact that boiling removes most all the contaminants. The only thing it doesn't remove beyond doubt though is heavy metals and salts. To do this at home, you will need a supply of water from somewhere fresh like the sea. You will need a pot to boil it in say over the fire and also a good filter. This filter should be what is known as a semi-permeable membrane. If you haven't that, then a good fire will do. Set a pot or a kettle atop that has a good lid and also a tube attached to the top. The water as it boils will collect in this tube, leaving the salt in the bottom of the pan. When using this method, you haven't need for a filter. With the other method, you will need both filter for the salt and boiling to remove other impurities. Perhaps though, the boiling needed won't be quite as long.

Water is basically made up of two main components that allow this to happen: oxygen and hydrogen. Its chemical name is spelled out as H2O because of the two molecules of hydrogen and one of oxygen. Yet it isn't just that, now is it. It's that and whatever other additives that are mixed in with it. This is why boiling water helps remove impurities so well, but it also will turn water into steam, or back into its same exact original form. There it combines with the air in the form of oxygen and hydrogen. Because of its' structure, it will settle back down again as vapor or condensation when it has cooled. Large enough molecules will even form rain if there is an unlimited supply. What do you think?
