What It IsWhen you need the truth, the whole truth, and nothing but the truth, grab the new Lie Detector Kit, from Wild Planet's Spy Gear line. The kit contains a sensor that monitors skin moisture, which increases when someone lies. This truth-detection method, modeled after the galvanic skin response system, is similar to the technology used in polygraph tests during real-life investigations. But kids can have this cool technology for well under $20!
Lights on the kit illuminate as more moisture is emitted from a suspect's fingertips. An increase in lights equals an increased likelihood that your subject is altering the truth. Track the spikes and dips in the light levels to surmise if certain topics are consistently met with dishonest replies.
Because a good detective does not rely on technology alone, the Lie Detector Kit also comes with a clue booklet that shares psychological techniques kids can use during "interrogations." If the suspect shifts his gaze to the right, or if he leans away, he could be stretching the truth.
It may not be necessary to say, but this is really a toy and, as they say, "for entertainment purposes only." You will certainly get responses based on the technology, but we have a sneaking suspicion that these results would be inadmissible as evidence. Nonetheless, it's a lot of fun.
