Lie Detector

 

Learn about electricity with the Magnoidz ‘Lie Detector’ science kit for inquisitive minds!

 

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.

 

Ever feel like someone is not being completely honest with you? Get to the truth of the matter with the help of science! This kit has all you need to build your very own this kit, including a sturdy case, circuit board, meter, aluminum plates and detailed booklet with instructions for different experiments. There is no soldering required, so you will be ready to test your first suspect in a matter of minutes! Because the lie detector detects electrical current, it also doubles as a conductivity meter.

 

One 9V battery is required
