Re: Aluminum foil wraps prevents black water?
Hi! I'm from Bangkok, Thailand. Silver wire in water seems to be consistent enough on multimeter tests. Water shows a good constant negative water. And it is possible you do not need batteries. Of course whether it works for you or not I do not know. Apparently you are right, silver is a good positive conductor. Apparently it absorbs positive and makes water negative.
I actually tested many metals gold, silver, copper, zinc, and various chemicals. Seems that silver is one hat is most consistent. Gold seems to work along with silver, but I cannot prove that yet based on
Edgar Cayce 's comment that you could double your life span drinking gold and silver vibrational water or something. There is some proof of Dudley Delaney who was treated with Multiple Sclerosis using
Edgar Cayce 's device. He is 63 years old but looks like 33 years old. No kidding since I checked out his profile, etc.
So conclusion: silver makes water negative polarity. Whether it works or not on your health you really need to try it out. It doesn't need batteries. But for proper maintenance you may need to get detergents to clean the silver wire.
