Have you ever heard anything about the history behind the lie detector? In fact it has quite an exciting past! In 1902 an inadequate lie detector test was invented by a man named James McKenzie. Later on in the 20th century, 1921, a medical student named John Larson from the University of California invented the modern polygraph instrument, which was much more accurate in its results than the previous machine. Since then the detector has undergone lots of changes, and today it's perfectly shaped for another hilarious challenge!
