Tesla Coil


Named after its inventor, Nikola Tesla, this high-energy device is used when great amounts of light, heat and energy are needed for sustained periods of time. The typical coil consists of placing two metal rods (usually steel and brass) in a salt solution, and running a small electric charge into the solution. The electricity runs up both of the metal rods, releasing electrons into the air, with the positive electrons moving to the brass rod and the negative to the steel rod. As these electrons move faster and faster, strong electrical currents are built up and begin arcing between the two poles. You see the same thing happen anytime there is a lightning storm.
