Zapping etc

My husband built me a zapper. He is an electronics tech so it was a small matter for him. I used it for a long time and never really saw any results, no little beasties, no die off symptoms. And it never really did much good in stopping a cold as Dr. Clark claimed. However, that does not mean that I don't think it works. I did notice that I didn't feel the tingle till I had been using it for a few days in a row and never when I wrap the handholds in wet paper toweling. Hubby says that water alone is not the best conductor, and to add salt to the water for best results. So what I have been doing of late is to moisten my palms with a little saltwater before grasping the handles and I feel the tingle much more readily. I wonder if it will make a difference with the beasties. Anyone else? Tweet
