You need 2 small rods of silver (I don't know if its a certain type/grade) I'll ask my mate asap, and a car battery, hook up one rod to the positive and one the the negative terminal, dip the rods in some water, it should start creating bubbles from either rod, leave it for a minute remove the rods and disconnect the battery and drink the water, it should have a blue colour but not that blue, drink this once a day and your resistance to disease and infection will be greatly increased, this WILL keep you healthy now or post shtf
