This palm size lie detector is a perfect party accessory - next time your friend will lie about their last raise or their latest nite adventures - be sure you will know the truth. The DeFIBulator works by measuring voice stress, which tends to increase when someone is playing fast and loose with the truth. When the device detects that someone's lying, watch the LCD screen as "Demonochio's" nose gets longer and he sprouts devil horns! It even works with a cell phone. Just be prepared - the truth is not always plesant.
