Lie Detector Mini Science Kit

This fun to use lie detector kit demonstrates the principles behind the big lie detector machines. By detecting changes in human physiology that occur when someone doesn’t tell the truth, you can tell with a reasonable degree of accuracy how accurate their statements are. Of course, this one may not be ready for the interrogation room, but it’s a fun experiment.
