Product details

Lie Detector Kit

• Build your own lie detector
• Catch your family and friends out when you think they’ve been lying
• Powered by a single 9v PP3 battery

How does it detect lies?
This kit demonstrates the basic principles of lie detection. Using small components it detects the change of resistance of the skin in the presence of sweat. By doing this it will illuminate either the green LED for true or the red LED for false allowing you to find out whether someone is lying or not.

How difficult is this to put together?
This kit is for the beginner due to the less complex nature of the components. It is a great tool for teaching children and the less technically advanced the basics of circuitry. It is advised that children are supervised when handling a soldering iron as these can be hot!
