An activated by an electric current of water appear special properties: such moisture has a significant influence on the course of redox processes in animate and inanimate nature. Using the activated water, the enthusiasts achieve success in a wide range of areas from production to consumer (publications on obtaining “live” and “dead” water, see the journal “modelist-Konstruktor” № 12’83, 3’87, 3’96, 12’2000). Today’s collection is about the activators that can be done in a home workshop, based on the materials of the popular Bulgarian weekly “Guide yourself.”
