How to Make a Pickle Light Bulb
Keep in mind, you are dealing with LIVE AC! Use common sense and all possible caution! I grabbed ahold of one of the wires while discussing it infront of a group of Physics Pholks at Rutgers a few years back and got a rude awakening! Made the demo much more interesting for the audience, but ruined my day (not to mention my shorts...).
1) Get a pickle.
2) Jam electrical wires into opposite ends of said pickle.
3) Plug wires into AC socket.
