Someone mentioned using laser pointers as a way of checking colloidal silver.
I've never done this and I don't have a laser pointer but I read somewhere that you can shine a strong light through colloidal silver and then look for certain things. What I notice is that if I hold a small halogen flashlight against the side of the brown bottle with colloidal silver in it, I see a beam of light through the solution that looks like a fuzzy laser beam. By this I mean that the beam of light going through the solution is the same diameter all the way across the bottle and it looks kind of cloudy. Richard Ausili [email protected]
