Touch and Glow

The Touch and Glow is a device that we got from Grandma to turn any lamp into a touch lamp. It works by sensing the difference between the input neutral (which is connected to ground) and the output neutral. It doesn't really work on all lamps because on some the neutral of the bulb is insulated from the main metal of the lamp. I found a way around that by connecting a wire from the neutral of the bulb to some foil tape. I can touch the foil to turn on and off a light. I set up a light like this near my bed and I can touch the tape with my feet to turn on a light.
