“colloidal silver generator”
Sounds like something I may want to know how to make
For a colloidal silver generator you need a 1 pint fruit jar, three heavy duty 9V plugs (get at Radio Shack) two alligator clips (one red, one black) three 9V batteries and a 99% pure 1 OZ (we use Johnson Matthews) silver bar. Instructions for assembly are on YouTube.
