Experiment for grass tufts

[Gary S]

Reinhard, not to worry, I've been an electrician for 30 years now. To tell you the truth, with the 120 volts that we use over here, every time you walk barefooted on the ground, you are connected to one side of the power source without even knowing it. And, it isn't much different than using a 120 volt electric drill or a vacuum cleaner. Gotta admit though, it is a little more hazardous than the 12 volt model, but only for those who don't know what is going on.
