I want to construct a magic apparatus that will enable a small electric shock to travel from the device through my body to the spectator's hand just my touching my hand to theirs. I would really like to buy this device, but it's a little expensive, so I'd rather build one myself. Any tips?
Check the hyperlinked website for a preview of the real device and to understand the desired effect.

I have a 20kg Weight fixed to the end of a wire. If I was to lift the weight 1 Meter thus having 1 Meter of slack in the wire and let go of the weight. What will the force be on the wire when the weight stops. I'm looking for a formulas etc so I can size up either a new rope or alter the design of the weight on the end of the rope so it's not as heavy. I've tried several equations and have now got totaly confused as to which way to go.

Recently I was checking out an electrical failure at a friend's house and put a meter on the output of each of the breakers to see if failure had occurred in one, even tho they were not tripped. I was amazed to see that one of the two sides of the power read over 123 volts to neutral and the other read just at 120 volts.- American "110/220" house power. Appliances must work within a 110-125 range measured to ground but I expected the legs to be almost identical. I admit I haven't measured a bunch of them, so I ask here. [I contacted TXU Electric, but under deregulated power in Texas, they won't answer it referring it over to Oncor, the spun off power delivery company.]
