laser pointer cheap blue

You will learn how to do a simple "laser pointer blue test" to ensure that your
(http://www.kitlaser.com/80mw-100mw-200wm-aluminum-alloy-laser-p.html)colloidal silver solution actually has silver particles. The laser light test is the
simplest and least expensive method of testing a colloidal silver solution and visually shows billions of submicron silver particles suspended in the solution. Just enter a dark room, a transparent glass colloidal silver, and flash from top to bottom with a red laser light into the solution. However, if you have a red laser light in a glass of pure steam water, there is no laser beam at all because there is no mineral content in the red laser's steam water. This is how you prove beyond any shadow of doubt that your colloidal silver solution actually contains billions of suspended submicron silver particles. You will see a thin thin red light beam in the solution. That is because the red laser is reflected from the surface of billions of tiny submicron silver particles suspended in the solution, which in turn forms a thin beam of light.
