U.S. dollar bills are printed with special inks that contain traces of iron and other magnetic material in an effort to prevent counterfeiting. So, the only logical question that follows is, "Can you get the iron out of a dollar bill?" Steve Spangler accepted the challenge with the help of his friend, Bob Becker, who found a most unusual way to extract the iron from a dollar bill. You'll be amazed at how much iron is in a single dollar bill.
