body when they aren't telling the truth. If you
tell a lie, you feel stressed. And if you are
stressed, your heart starts to beat faster. The lie
detector measures your heart rate while you
are answering questions. It also checks your
breathing. You breathe slowly if you are
relaxed, but if you tell a lie, you breathe more
quickly. Finally, it measures the sweat on your
fingers. If you lie, you sweat more!
