When someone gives you a tutorial, and they say, " works 100%" and can prove, its time to pay attention. I've read the entire thread The definitive Coloidal Silver Tutorial. So I've built a rig and fired it up! Got to hunt arounbd and see if I can find my old laser pointer...lol! If not I'll just pour some into a solo cup, and check the ppm reading with my meter. And don't ya love the ACME label! Shades of Roadrunner! :smoke:
