Everyone agrees on .9999 silver(wire, a Maple), distilled water. A few say heat the water, several say agitate or keep the water moving in the glass container by whatever means. A laser or PPM meter to measure. The power source and maybe a resistor added seems to be the most widely varying thing i've seen.
I have most varieties of power sources available but how many volts and amps should a person use to hopefully end up with small particles(that's the goal, right?)?
