Product Quiz

Welcome to the Science Quiz 98

Let's Start Quiz

 

Lie Detector: A lie detector, or polygraph works on the principle that people who are lying tend to sweat more. Sweat is basically salty water, which (unlike pure water) conducts electricity. The subject of a lie detector test places their fingers where they will form part of an electrical circuit. If there is sweat on their fingers, electrical current will flow and cause the needle to be deflected. Best Christmas gifts 2021 kids.
