JOPLIN, MO.--- When it comes to new technology, kids often take to it fairly quickly. Many kids can use an iPad before they can even read, but what about when it comes to old technology? KSN's Brad Douglas had a chance to talk to some fourth graders at Mark Twain Elementary School in Carthage. He wanted to quiz them, so he picked out several items that were popular in their day to see if the students knew what they were. The first thing he showed them was a rotary phone.
