Find out who's telling the truth - and who's not - by giving your suspect a lie detector test. Attach the sensor to your suspect's finger. Ask tough questions to really make 'em squirm. The indicator lights light up when your suspect isn't telling the truth. Busted!

When you need the truth, the whole truth, and nothing but the truth - grab your Lie Detector Kit and get to work! 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.

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 comes with a tip booklet that shares psychological techniques you can use during interrogations. Watch to see if your suspect shifts his gaze to the right, or if he leans away from you; both are subtle indicators he could be stretching the truth.
