Personal Lie Detector - de-FIB-ulator (CES 2008) (VIDEO)

Have you ever been talking to someone who you were convinced was straight-up lying to you? More than anything, you just wanted them to cut the BS and tell you the truth? While they haven’t come up with pocket-sized truth serum, the de-FIB-ulator was unveiled at CES, a hand-held, personal lie detector.

The handy device, which only costs $39.95, was found at Alexander Innovation Wizard‘s Innovations booth at the Las Vegas expo this week. By measuring the vibration in voices, it detects lies with 65% accuracy.

“Ask your subject three simple yes/no questions and record them (either in person or by connecting the de-FIB-ulator to a cell phone) to establish a baseline,” Gear.ign.com explained. “Now ask the real questions you want to test. A figure displayed on the unit’s LCD screen nicknamed “Demonocchio” will show the tension in the voice. The longer the horns and nose grow, the more likely the answer was a lie.”

With this gadget, you could legitimately drill your boyfriend on whose blonde hair that really was on the front seat of his car. Then again, if he thinks you’re dumb enough to blame the specimen on his buddy’s shedding Golden Retriever, he’s probably worth ditching anyway.
