Colloidal Silver Test in our Petri Dish
When we first received our order of colloidal silver from you, I also purchased a batch of sterile petri dishes and swabs from a laboratory. I swabbed several surfaces (from the toilet bowl, the kitchen sponge, etc.) onto separate petri dishes, and then "flushed" half of the treated dish with colloidal silver.
After a proper incubation of several days, the side of the dish untreated with colloidal silver was rampant with bacteria. The side that had been flushed with your colloidal silver was either free and clear of bacteria in most cases, or had very little.
