In an earlier blog entry I wrote about the treatment of water in a Reverse-Osmosis system. I feel I have to add a note on storing water, whether it is specially treated or came straight out of the tap. It is certain that the quality of water can be improved in such a way that it flows better and is better capable of dispersing paint particles, provided the paint is also treated which I also described in a previous blog entry. Water, however, is a living organism of a unique and powerful kind.
In 2000 professor Ignatio Ochoa performed a test in which he heated sand from the beach in a glass laboratory test tube until it was white hot. This means that if there had been any form of life in the sand, the heat would have killed it. Then pour distilled water into that tube over the sand. Distilled water also contains no life of any kind. Next, seal the tube hermetically to prevent tiny life forms (bacteria from the air) from entering the tube. By doing these things, everything has been done to remove all forms of life inside the tube.
But lo and behold, after 24 hours in the top layer of the water, DNA structures are formed, which become visible under the microscope.... Out of dead matter life was created. This miraculous achievement of nature may stun all those who have command over more than two properly functioning braincells, but to airbrush artists who strive to perfect the behavior of their gun and the mixture of water and paint that it shoots, this is actually bad news.
So, start with freshly treated or freshly tapped water before each airbrush session if you want to be certain that you will get the maximum spraying result. In any case, do not use water that has been in your little container for a longer period of time. Nature can not be beaten; all you can do is respect its unbreakable creative power and humbly collaborate with it.
