A great party game for any gathering, Lie-Detector (LD) is a handheld voice-tension detector that measures degrees of vocal vibration to determine if someone is telling the truth. When a subject changes from a state of calm to one of nervousness, it's reflected in tense vocal chords!

To train the LD, ask your subject three easy "yes" or "no" questions. LD records the answers, establishing a baseline reading. Then, ask serious yes/no questions. If the subject isn't responding honestly, the onscreen face of "Demonio" grows a long nose and horns.

The greater the tension, the longer the appendages!

Purported accuracy is 65 percent.

Works with cell phones!

Measures 3 1/2" x 2" x 1/2".
