The Debunker: Are Power Lines Insulated?

by Ken Jennings

In July 1820, Danish scientist Hans Christian Oersted published a groundbreaking pamphlet on the relationship between electric current and magnetic fields, effectively kicking off our modern electric age. You may think about electromagnetism every July when you look at your power bill and see how it spikes when your air conditioner is on. In honor of everyone getting zapped by the electric company this month, we've asked Jeopardy!'s Ken Jennings to set us straight on some high-voltage misconceptions about electricity, correcting all of our shocking ignorance.

Live From the Internet: Star Spangled Banner Edition

by Kathleen Richards

Well, well, well, friends. 4th of July is soon upon us and it's time for me to share one of my favorite yearly traditions with you: watching internet videos of people butchering the national anthem.

Yes, our national anthem is a patriotic masterpiece. Yes, it's a beautiful poem and a beautiful piece of music. But it's also very hard to sing and very hard to remember the words to.

Which is great news for those of us who can't get enough of these videos where people can't hit any of the notes or remember any of the words. Let's start off with a classic.
