This passed week Tom Vales came to our class and talked about electricity and also showed us a tesla coil.  Vales talked about the differences between Nikola Tesla and Thomas Edison. Tesla did a lot of work with just himself and one lab assistant, while Edison did the same amount of work, but had many lab assistants. Vales also told us we have tesla to thank for why we have alternating currents. The tesla coil he showed us consisted of a plastic bucket wrapped in wire and was attached to a motor.

Vales continued to show us neat things about the tesla coil by holding lights near it. Just by holding lights near the tesla coil they would light up.

Overall the whole talk was extremely interesting. I have read somethings on Tesla so it was nice to learn more about him and also see how one of his inventions worked.
