The manufacturers of the DeFIBulator Lie Detector claim that this hand held unit can measure stress, tension, excitement and variations in a persons voice to separate the truth from the lies.
All you need to do is establish a baseline by asking your subject a few yes or no questions, then you can start the real interrogation. If the device determines that your subject is lying, the “Demonchio” on the screen sprouts devil horns and a longer nose. The DeFIBulator can even be connected to your cellphone so you can conduct covert interrogations.
The DeFIBulator probably doesn’t work, but it would be a fun diversion at parties. The device retails for $39.99.
