Tesla Coil

When I was at the expo, we went into this one room. It had this big machine called the Tessla coil. It’s an invention that was supposed to transmit electricity in the air, but instead it’s a good way to make lightening. The demonstrator turned off the lights and then turned it on. He said it was going to be a little loud and he was right. Purple lightening came from the machine. It was really cool.
