Why do people always assume that electronics are dangerous? Seems like if there is a wire or two, everyone assumes the worst and panics.
Actually, people panic over all sorts of stuff these days. Among other things, I used to play with a chemistry kit and model rockets when I was a kid. The local hobby shop used to sell rocket motors to kids, no questions asked, either. That would probably get someone arrested today.
The local Walmart keeps the rocket motors in a locked glass display case
