One of the latest additions to Hammacher Schlemmer’s online catalog is a lie detector that works similar to the professional polygraph but allows you to perform tests at home.
The kit consists of pulse and skin monitors and works while connected to your computer running Windows or Mac, via the USB cable. You need to apply the included sensors to the subject’s fingers so that the system can start reading the pulse rate and skin’s electrical resistance. The system then measures changes in response to questioning and data is displayed in real time through the included software.
The Home Lie Detector Test seems to be a cool kit that you could use for fun and is available for purchase at Hammacher Schlemmer for $399.95.
